newbie: Help, I have problems with this!

hey
asp.net 2.0
visual web developer 2005 express
I have a webpage which contains 1 Repeater control. Into this repeater
control I want to add several rows of data. My problem is that 1 of the data
is an array of bytes (it's a picture saved to the database as bytes) and I
want that picture to be displayed nicely in the repeater list...
Here is two approaches (approach A and approach B) I'm trying:
APPROACH A:
Use the scenario of 2 .aspx files, 1 .aspx (A) convert the bytes of array
into a picture and the other .aspx file (B) has a img tag pointing to the
first .aspx file (A)
But here I get problems with this line "img.Src =
"Thumnail.aspx?ImageID=1";", it looks like it expects a object... Somehow I
need to send over a parameter to this Thumbnail.aspx file about which image
to display... Lets say the resultset has many images, but this row shall
display one particular image
protected void rptInbox_ItemDataBound(object sender, RepeaterItemEventArgs
e)
{
System.Web.UI.HtmlControls.HtmlImage img = null;
if ((e.Item.ItemType == ListItemType.Item) || (e.Item.ItemType ==
ListItemType.AlternatingItem)) {
img =
(System.Web.UI.HtmlControls.HtmlImage)e.Item.FindControl("Photo");
img.Src = "Thumnail.aspx?ImageID=1";
}
}

APPROACH B:
In this approach I tryed to replace the img tag with a Image control in the
repeater.
But the "System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(mstream);"
gives this error:
"Parameter is not valid."
Another thing is that I'm not sure this is a good approach because it uses
bmp.Save() and I'm afraid the server will run out of space if images get
saved on the server each time th page is displayed?
protected void rptInbox_ItemDataBound(object sender, RepeaterItemEventArgs
e)
{
//System.Web.UI.HtmlControls.HtmlImage img = null;
System.Web.UI.WebControls.Image img = null;
if ((e.Item.ItemType == ListItemType.Item) || (e.Item.ItemType ==
ListItemType.AlternatingItem)) {
img =
(System.Web.UI.WebControls.Image)e.Item.FindControl("Photo");
byte[] data = Profile.Picture;
Int32 offset = 78;
System.IO.MemoryStream mstream = new System.IO.MemoryStream();
mstream.Write(data, offset, data.Length - offset);
System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(mstream);
bmp.Save(Server.MapPath("sample.jpeg"),
System.Drawing.Imaging.ImageFormat.Jpeg);
mstream.Close();
img.ImageUrl = Server.MapPath("sample.jpeg");
}
//e.Item.DataItem.ToString();
}
Please help me with this one, I'm stucked in this problem...

Newbie: How do I create Dynamic instrument widgets in ASP.NET

Hello,
I want to create a dynamic web page, which presents various instrument
widgets (Temperatures, pressures, rpm gauges, speeds etc.) in a
browser, with continous data updates from Server side data. Obviously
these instruments need to be constantly refreshed (every 0.5 second or
so) and not just on page load.
With Windows Forms, and GDI I can do this with networked Thick Client
code. I can also do dynamic web instruments with Java Applets, and I
guess DHTML/Javascript. But I really want to do the instruments in C#
and .NET. But I don't think that I can achieve this, because http and
ASP.NET is based upon a page based paradigm. The new ASP.NEt is based
upon Server side controls, that won't refresh my instruments with live
data, once the page is downloaded. (Traditional DHTML/Javascript looks
like a real pain to develop instruments in.)
I am agreat fan of .NET technologies, but I was hoping for better MS
and .NET support for these instrument based web applications. But I
guess my only real choice is Java Applets !
Any suggestions on how I can achieve dynamic web instruments with .NET
technology would be appreciated.
Thanks
JulesThere may well be other ways of acheiving this kind of thing, but you could
just refresh the image (in JS) representing the clock
or you could use the WebBehaviour stuff, this will allow you to connect to a
webservice on the server (using JS again) then you can update your clock or
gauge or whatever in the JS on the client.

I'd say your requirements don't lend themselves to building a browser based
application. Consider building a traditional fat client app using ClickOnce
or NoTouch Deployment. A java applet is really no different.

Newbie: How safe is source code?

Hi

I am a complete newbie and am contemplating moving to asp.net from asp. How
protected is an asp.net web site source code should it be delivered to a
client?

Thanks

RegardsMy opinion:

If your concern is about protecting access to the code itself, then ASP.NET
source is much safer than classic ASP, because the deliverable is actually a
set of compiled .dll's, rather than a set of vbscript files.

However, you should be aware that it is notoriously easy to decompile a .NET
assembly into very clean source code. If this worries you, you should
consider using an obfuscator to "scramble" the dll code so that decompiling
either doesn't work or doesn't work very well.

Hi John,

You should obfuscate your ASP.NET with Dotfuscator (a .NET
obfuscator).
A lite version is included inside VS.NET 2003 under the tools menu.
This will make reverse engineered code harder to understand.

If you want more protection that significantly hinders reverse
engineering by crashing or stopping decompilers and support look at
Dotfuscator Professional Edition.

For more info: www.preemptive.com/dotfuscator

Dotfuscator Team

I agree. But what about 'Whidbey' (new VS 2004)? I think we going
back to no code-behind'.

Even with 'no code behind' isn't the result still .NET code which can be decompiled?

Newbie: How to display search results?

I am new to ASP.NET, so probably my question is very basic:

I have a web page (page1) where I allow the user to make a search, text box
plus a botton (botton1).
When he click the botton (button1), the server obtain (from memory) an array
of Products Id.
I want to open a second web page (page 2) with the results (obtained from a
database using the Products Id), the results will be shown in a datagrid.

My question:
- If Once I clicked botton1 I retrieve from de database the Products (using
the array of ProductsId and a datareader) how I bound this datareader to the
datagrid in page2?.
- I think there is a second option: I pass the array (memory array) of
products Id to Page2 (how i do it?) and the Onload event of Page2 read the
data from the database and show it in the datagrid. How I pass the memory
array to Onload event of Page2?.

I am pretty new to ASP.NET so I suspect there is an standard way of doing
this, I welcome any suggestion.

Thanks,

JaimeI am new to ASP.NET, so probably my question is very basic:

By "open a second page", do you mean "open in a new window", or just
"replace the current page"? If new window, then see if there is a
"target" attribute on that button (button1). If current page, then
nothing special needs to be done.

To pass data from one page to another, there are several options:
- querystring, like "page2.aspx?searchtext=bla". Best for a small list
of short values, that can be represented by a string.
- Session data. In page1 you store "it" in the session
(Session["productids"] = list) and in page2 you read it, casting as
required ( int[] list = (int[])Session["productids"] )

You can perform the search in page1, passing the results (via Session)
to page2. Or you can pass the searchtext to page2 (session or
querystring), where the complete search is performed. I like the second
option better, as you concentrate the "search functionality" in that
page.

Newbie: How to upload and save images using ASP.NET web forms (C#)

Hello -

I need to upload images in my web application using ASP.NET web forms
(written in C#). Since i have never done this before, i am unsure what is the
best method.

I assume there are two options:

1). Upload the images and save the files directory to the windows file
system. However, i assume this poses a security risk, as the file directory
will require write permissions.

2). Save the images (as objects?) in the SQL SERVER database.

Can anyone suggest the best way to do this? And, if possible, point me to
some sample code or artciles which explain how to do this.

Thanks!Charlie,

check out the following article:

http://www.codeproject.com/aspnet/fileupload.asp

I prefer to save files in the database but it depends on your needs.

If you need to save hundred thousands of files and decide that you want to
save them on your hard disk make sure to distribute them on different
directories. What you could do is that you assign a guid to each file and
create your directory structure accordingly.

Example:

You have five files with the following guids

0A59E8D6-0AE5-475B-8698-814C2C712029

F16CE1B1-56D0-42E6-9463-A58D553CC289

D90C27C7 -8BD9-4F47-8CFE-DE9D240AD136

370B6080-DF06-4DDE-BB5E-85264B8AE48B

861DC387-FDC7-4A4F-B0C3-9EA6734A562A

You could now create a directory like the following:

0A59E8D6\0AE5\475B\8698\814C2C712029

F16CE1B1\56D0\42E6\9463\A58D553CC289

D90C27C7 \8BD9\4F47\8CFE\DE9D240AD136

370B6080\DF06\4DDE\BB5E\85264B8AE48B

861DC387\FDC7\4A4F\B0C3\9EA6734A562A

newbie: HTML controls vs Web controls

The System.Web.UI.HtmlControls namespace is for HTML controls, in the
sense that they are declared on the page using standard HTML tags, for
example "input", "select", "textarea", etc...
The System.Web.UI.WebControls namespace is for ASP.NET controls, which
are declared on the page with an "asp:" prefix, for example "asp:Checkbox".
The different is that in the first case, they're client-side controls.
You use them on the server in order to set attributes, scripts, etc...
which are executed on the client. In the second case, however, (and
while you can also influence the way they will be rendered on the
client), the events you wire them to are executed on the server
(involving a postback).

It depends on what you are more comfortable with. If you come from Windows
application background, you will find that web controls are more friendly
and they are a less dramatic change from your previous experience.. If you
come from html background you will like html controls. As you master your
asp.net skills, you will likely lean more towards html controls as they give
you better control over client-side functionality.

and when to use HTML controls?

newbie: I wonder if this is possible in asp.net 2.0

Hey

asp.net 2.0

As far as I know it's possible to search the users registrered at a asp.net
2.0 web portal using either username or e-mail.

But what about the custom profile properties which can be configured in
web.config? Can they be searched too? I guess it can by using foreach loop
and test the contents on every user object.. but I thought maybe there was a
cleaner and faster way to do it...

Lets say for example these are custom profile settings in web.config. any
suggestion on how to search them? Lets say the search should return all
users containing the phrase "Lets" in lastname? or all users of a specific
gender?
<profile enabled="true">
<properties>
<add name="FirstName" type="string"/>
<add name="LastName" type="string"/>
<add name="Gender" type="string"/>
<add name="BirthDate" type="DateTime"/>
</properties>
</profile>

Best RegardsThis article should help, and even fleshes out some of the sample code
provided by one of the MS people for it:

newbie: inserting data into sql form writes only null values

Hi,

using VStudio 2005/sql server 2005

Have a simple web form that inserts the results in a table. It seems to
write to the table, but not the values from the asp forms fields. It adds a
new record and increments the id field by one -- but in all the other
fields, it merely writes Null to the fields. He are some other points:

I am not inserting data into every field -- for test purposes I am only
using 4 fields.
The id field is NOT one of the fields on the asp form -- although it is the
only field that actually writes a correct value

here's the code:using VStudio 2005/sql server 2005

here's the code:

<asp:TextBox ID="FirstName" runat="server"></asp:TextBox> 
Last name:
<asp:TextBox ID="LastName" runat="server"></asp:TextBox> 
Address:
<asp:TextBox ID="Address" runat="server"></asp:TextBox>

Hi there,

Use

ControlParameter instead of FormParameter. The difference is that
FormParameter takes its value directly from Request.Form collection using the
name given by FormField. The problem with your vode is that, textbox does not
post its value in Request.Form[textBox.ID] but in
Request.Form[textBox.UniqueID] which reflects IDs of the parent controls.
Change you insertparameters declaration to:

Thanks Milosz, it worked.

I'm confused why the book had me use the FormParameter and FormFieldID --
but thanks for getting me past this point.

Take care.

newbie: installing visual web developer express 2005

Hey
When installing visual web developer 2005, the installation suggest
installing on C: But I want to install it on D:, because I only got 1.6 GB
available on C: and D has 30 GB available...
So I change installation location from C:\Program Files\Microsoft Visual
Studio 8\ -> D:\Program Files\Microsoft Visual Studio 8\...
But even if I change to D: the installation says it will install 1.8 GB on
C: and 78 MB on D: (When C: is selected, it install everything on C:, all
the 1.8GB)
Is it possible to install everything on D: or do have to delete files from
my C: to make space for visual web developer 2005 express? This is on a
winxp pro system. I want to have atleast 1GB free space on C: for swap files
etc (maybe I should change the swap file to d:)
any suggestions?
JeffHi Jeff,
The .NET Framework, on which VWDE relies, wants to be installed on the
system drive, which is probably C:.
You could move your swap file to D: and might even see a performance gain.

Hi, Jeff.
VS 2005 requires a lot of available space in the system drive,
although there's a lot of it you can install on a data drive.
The choice is available at setup time.
If you have 30GB free on D: and only 1.6 GB free on C:, what I'd suggest
is that you install WinXP Pro on D: and make D: your system drive.
You can then not have to worry about free system drive space, and you can ea
sily
install VWD Express and SQL Server 2005 Express on your new system drive ( D
: ).
You will breathe a lot easier after you do that.
Then, you could wipe clean your C: drive and place your swap file in it.
Sometimes, a clean break is a much better choice.

Use
ControlParameter instead of FormParameter. The difference is that
FormParameter takes its value directly from Request.Form collection using th
e
name given by FormField. The problem with your vode is that, textbox does no
t
post its value in Request.Form[textBox.ID] but in
Request.Form[textBox.UniqueID] which reflects IDs of the parent controls.
Change you insertparameters declaration to:
<InsertParameters>
<asp:ControlParameter Name="lastName" Type="String" ControlID="LastName"
PropertyName="Text"/>
<asp:ControlParameter Name="firstName" ControlID="FirstName" Type="String"
PropertyName="Text"/>
<asp:ControlParameter Name="address" Type="String" ControlID="Address"
PropertyName="Text"/>
<asp:ControlParameter Name="city" Type="String" ControlID="City"
PropertyName="Text"/>
</InsertParameters>

Thanks Milosz, it worked.
I'm

why the book had me use the FormParameter and FormFieldID --
but thanks for getting me past this point.
Take care.

newbie: Master pages... dynamic content...

Using VS2005, VB codebehind,
I'm porting a windows app to the web - My main page is very simple and
will look something like this:
----
| Title |
----
| | button navigation bar |
| | ---|
| | |
| Menu| |
| | Content |
| | |
| | |
| | |
---
Menu is a treeview control that is (potientially) different for each
user that visits the site. (nodes are dynamically populated in the
treeview via code behind based on user's role and auth. level)
The Content can be any object renderable by a browser (HTM, flash, pdf,
office document, etc).
The question is can i display different web forms in the content part
when the menu is clicked?
I've looked at master pages but from what I understand they would only
be able to display HTM in the "Content" area. Does anyone have any
ideas on how to allow the content area to display other types of
objects?
Can anyone help a web rookie ?You have some incorrect notions.
Master pages can have dynamic content. The isue is they are a little harder
to ahve the page update master page content, but it is not impossible. And,
if you have the master page render dynamically, there is no issue. I see no
reason why a user driven menu cannot be placed in a master page.
If you use master pages, the different content is fairly easy. If not, you
will need another option. DotNet Nuke is an option and would be easier than
rolling your own.
Third choice, way out in left field, is to create your own engine to render
the pages. I would inherit from page to do this, as you can have your class
handle most of the lifting. User controls are also an option for content, if
you wish to use a model-view-controller type of set up. I would shy away
from any of these choices, esp. as a rookie, unless the master pages and
DotNet Nuke fail to work.
NOTE: Check out the starter kits under downloads at www.asp.net. They will
give you a good framework to start from.

I have a treeview in a master page, and I display pdf files(EKGs and X-Rays)
in the content pages using an <embed> tag. The 'src' attribute of the embed
tag is assigned when the content page loads based on the query string used
to open the content page when a treeview node is clicked.

Gregory,
Thanks for the reply. I'm excited at the possibility of making this
work.
I've got hundreds (if not a thousand) content pages that I need to be
target for the "child page". Problem is I don't want to modify all
the pages - in fact, the majority of the pages are on remote servers
that I have no access to - so I really just need to be able to point
to a URL and have it load in the child page. Can I still use master
pages to make this work?
I've reviewed ASP.NET downloads haven't found anything that suits my
situation - any other pointer or code snippets would be greatly
appreciated! Please Let me know what you think either way.
celoftis
Thanks... I'll keep that in mind.
The content inside a 'child page' needs to be inside a ContentPlaceHolderID
control. Also - the page needs to have the .aspx extension and have a
reference at the top of that content page, to the master page.

David,
Thanks for the reply...
So, for my specifc situation (not being able to access all the content
pages), it looks like master pages are not going to work - do you
agree?
But if I could modify the content of all the child pages, then I could
use a script to wrap the existing page(s) with
ContentPlaceHolderID(s)... seems real messy.

JeffThere are instances where you need to strip out the garbage from a site,
esp. if you publish instead of just copy all source (the latter being a bad
thing in a production site). Open the web config and remove the assemblies
add lines for the dlls in question (under <compilation>). If you have
already compiled (published), they are not needed anyway. That is what I
would try first. If it does not work, follow up and the issue can be dug
into deeper.

Well, the obvious answer is to change the hyperlink to point to Login.aspx
instead of home.aspx, but I guess that's not what you really mean...

Can you explain in a bit more detail what you're trying to do...

newbie: Problem getting the querystring!

hey

asp.net 2.0

in the page_load event of a web page I place this code:
NameValueCollection parameters = Request.QueryString;
string username = parameters[0].ToString();

The URL has a querystring, for example like this: Default.aspx?user=newbie

But this code don't get the querystring, the parameters collection gets no
entries from this line "NameValueCollection parameters =
Request.QueryString;"

What am I doing wrong here?

string username = Request.QueryString["user"];
Best bet is to access the querystring collection directly. I'm not sure if
it's something that can do like this, as normally a lot of collections are
copied using the CopyTo method, but this is usually done for arrays not
specialized collections.

Your best bet though is to access it directly from the querystring. Also,
don't use positional identifiers to determine a parameter, it's too easy to
change the order that things will appear in so it's best to use the keyname
instead. Also, don't forget to test for null first or else it'll bomb out
when you run into a case where it's an empty value, that's the most common
gatcha when using the querystring.

to get the whole collection you can use

Dim coll As NameValueCollection
