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: I need some tips

IDE vs .NET 2003
OS: XP pro sp2

I need to create a asp.net page which will receive data sent to it via
GET... The data sent into the page is a number, this number should be added
together with the numbers sent into the page by other users...

for example:
user A: http://localhost/test.aspx?value=1
and
user B: http://localhost/test.aspx?value=2

if user C want to retrieve this value, he should get the value 3 (1 +2)

Here som of the code in my Global.asax.cs:
public class Global : System.Web.HttpApplication
{
/// <summary>
/// Required designer variable.
/// </summary>
///
int b;

protected void Application_Start(Object sender, EventArgs e)
{
b ++;
Application.Add("test", b);
}

As you can see from my code above, I'm trying to fix this problem using
HttpApplication... Is that the correct approach? If it isn't, what is the
correct approach then??

JeffUsing Application is fine...but you should be putting it in the
Application_BeginRequest method, or the Page_Load of test.
Application_Start fires once and only once so it'll never add. It's hard to
advise without knowing more in detail. I'd be tempted to scoping this out
to the test.aspx page.

The following code will in no way compile, but should give you a general
idea

page_load
int userInput;
try{
userInput = Int32.Parse(Request.QueryString["value"]);
}catch (Exception ex){
if (!(ex is FormatException) && !(ex is InvalidCastException) && !(ex
is OverflowException))
throw;
}
object o = Application["totalCount"]
if (Application["totalCount"] != null){
((int)Application["totalCount"]) += userInput
}else{
Application["totalCount"] = userInput;
}

newbie: I don't want my .aspx and .cs files to have the source viewable by the client

I'm creating a C# .net project, for a client. However they only have the
right to the binaries, not the source code. Is there a way to compile it so
that I just give them dll's? or do they need the .aspx pages. I read
somewhere that I could probably make assemblies (excuse my bad terminology)
of the source code, but that it is quiet easy to disassemble the assemblies,
so that does not seem to afford read protection.
or am I just all over nothing!
thanksYou need to give them the ASPX pages and the compiled DLLs, but you do not
need to give them the .CS source code files.
If they are unethical they could decombile the DLLs to get a rough
approximation of the source code, but you can thwart them with an
Obfuscator.
Visual Studio 2003 has a basic built in obfuscator, but for 2002 you'll need
a 3rd party solution.
Here's more information on obfuscators:

FYI - Just remember there are Deobfuscator out there. But at least you are
taking some sort of measure to secure the DLLs.

newbie: image problems again

hey

asp.net 2.0

my problem is that on a webpage am I trying to dynamically display the image
a user has uploaded. But the webpage doesn't display the image. The browser
displays the standard image telling that image not found / broken image link
etc...

This is the code which saves the image to hard drive...:
fullsizeImage.Save(Server.MapPath("~/Images/Fullsize/" + Profile.UserName +
".jpeg"));

This is my code for displaying the image, it's in Page_Load event of
webpage:
imgPicture.ImageUrl = Server.MapPath("~/Images/Fullsize/" + Profile.UserName
+ ".jpeg");

The image exist in that folder

Any suggestions to this error?

JeffHi Jeff,

does this variable "Profile.UserName" really exist when you try to load the
image. Did you place an exception-handler around the loading-method?

Bye,

Hey

it looks like Profile.UserName is empty...
But this code doesn't work either:
imgPicture.ImageUrl = Server.MapPath("~/Images/Fullsize/test.jpeg");

I've also tryed this (setting it directly in the source, not the code
behind):
src='<%# Eval("~/Images/Fullsize/test.jpeg") %>'
Without any success...

any suggestions?

Jeff

Hi Jeff,

I am not sure what your problem is, but try one of these two things:
1. If you are using something like VS.Net, then simply try to locate a
test image using the properties grid of the Image Control. And then try
to run your page and see if it works.

2. try printing the path you are trying to assign to the ImageUrl
property by using a Response.Write() from the code behind.
So basically Response.Write(Server.MapPath("~\....

I have a feeling you are doing a bit too much in trying to assign a
path to the ImageUrl property.

The path is
C:\Documents and Settings\Jeff\My Documents\Visual Studio
2005\WebSites\BN\Images\Fullsize\test.jpeg

I've checked and path is correct, but the path contains spaces...

I'm not sure about it but maybe the browser need to know if this is a
picture ("image/thumb")?

It is possible that you may need to grant permission to the asp.net
process on that image directory. It might be a problem with the
security.

I replaced this line:

imgPicture.ImageUrl = Server.MapPath("~/Images/Fullsize/test.jpeg");

with this line

imgPicture.ImageUrl = "~/Images/Fullsize/test.jpeg";

And now it works

Thank you very much for helping me with this. The best thing with this
problem is that I've learned from it -maybe using Server.MapPath isn't
best all the times...

Best Regards!

I am not sure what your problem is, but try one of these two things:
1. If you are using something like VS.Net, then simply try to locate a
test image using the properties grid of the Image Control. And then try
to run your page and see if it works.

2. try printing the path you are trying to assign to the ImageUrl
property by using a Response.Write() from the code behind.
So basically Response.Write(Server.MapPath("~\....

I have a feeling you are doing a bit too much in trying to assign a

Hi Jeff,

does this variable "Profile.UserName" really exist when you try to

the image. Did you place an exception-handler around the

Newbie: Image button aspect ratio

I have some image buttons which I am dynamically adding from a database. No
problems so far...
However, when it loads the image using IMAGEURL=, it doesn't keep the
original aspect ratio.
Is there a way to keep this without resizing the control?
Many thanks,
David Whitchurch-BennettThe aspect ratio is not affected at all by the ImageURL property. Most
likely you have the height or width of the control set to a value. If you
remove those values from the control, the image will come in at its normal
size, if you want it smaller (but wish to preserve the aspect ratio), then
just set a width or a height for the control but not both.

Thanks for that information. What I have in my app is an image button set to
250 x 250, with a thick border which is all part of the visual theme. That i
s
why I have set the size first. What I want to do is load an image dynamicall
y
in the center of the image button, but keep the image button border the same
size, so the visual theme is preserved.
Is this possible, or will the only way be to place the image button into
another container with a border.

I think this is more of an issue of having graphics that will fit into a
250x250 space that VS.NET sizing the images for you. Your best bet is to
use a good graphics tool to create images that will fit into that space,
rather than attempt to have VS.NET fit them for you.

I already have this. I am using a class that I have written to scale down th
e
image first for two reasons.
1. To help the page load faster.
2. To prevent people downloading the full size images (photographic website)
.
Rather than resizing all of my photos, my class takes care of this by
scaling down the image. I pass the maximum width and height, and the image i
s
scaled down to fit and it maintains the aspect ratio.
When I put the scaled down image into the button, it stetches it out to fit
in both dimensions.
I guess I just asumed there would be a way to display the image without
stretching it out. I can pad the extra pixels in the function to return a
square image if that is a better way.
Thanks for your help. ASP.NET is quite different to what I am used to, but I
am getting there!

How about putting the image into an image control (not a button image
control) and overlaying the image control on top of your button control?
