for loop
{
ImageButton img = new ImageButton();
img.ImageUrl = "a.gif";
img.Attributes.Add("onmouseover", "this.src='" + imgMouseOverURL + "'");
}
Hello, I have an imagebutton instance dynamically generated. The code works fine except the mouse over effect
on the button becomes a big red X everytime my mouse hovers over the image. Does this have something to do with the dynamic generation of my imageButton? On the contrary, if I have an imagebutton available in markup with similar attribute, everything works fine.
Please help.
Thank you.

try doing a "View source" on the generated page to see what is actually sent down to the browser, and how it differs from the markup code that works
I'm not quite sure about your for...loop ? However you're looping, you can't create more than one control with the same ID...

ImageButton accepts 'ImageUrl' attribute rather than 'Src' attribute which is an attribute for HTML Image.
Try modifying your last line of code to---
img.Attributes.Add("onmouseover", "this.ImageUrl='" + imgMouseOverURL + "'");
Hope this works

No, that's not right. The Attribute that that line adds is to the control as it is rendered client-side, and therefore you must use the client-side properties. The original code is right, in that respect.

Hi,
I am trying to create a setup program to deploy a .net 2 web app. When I right-click on the setup project and then go Add -> Project Output, I only see "Content Files" in the Add Project Output Group dialog box. Why do I not see the other options like "Primary output", "Localized resources", "Debug Symbols", etc.?
Any help would be greatly appreciated. Thanks in advance.
Regards,

Hello, I'm working on an internal e-mail utility to send messages to different groups from a database. One feature i'm implementing is the ability to add e-mail attachments. I have every thing working the way it should but it seems if a user tries to attach an Exe file, the page breaks.
for instance, if you had the file "breakit.exe" and tried to attach it, it would give me a "page cannot be displayed error" after I hit the "upload" button. if you try this with a .jpg, .txt, or anything it works, but the page breaks even if I try to change the name of "breakit.exe" to "breakit.notanexe".
Does any one know how to detect this problem before the page breaks?
thanks,
-Ian.M
if ((File1.PostedFile != null) && (File1.PostedFile.ContentLength > 0))
{
string fn = System.IO.Path.GetFileName(File1.PostedFile.FileName);
string SaveLocation = Server.MapPath("Data\\" + ParentSessionID.Value);
if (!System.IO.Directory.Exists(SaveLocation))
{
System.IO.Directory.CreateDirectory(SaveLocation);
}
try
{
File1.PostedFile.SaveAs(SaveLocation + "\\" + fn);
}
catch (Exception ex)
{
}
}

What do you mean by "the page breaks"? Where is the code sample you provided being run? Is this part of the code that handles the upload button?
If you don't want to allow executable files at all, you could probably use the System.IO.Path.GetExtension method to get the file extension. If the extension is ".exe", don't upload the file. Of course, this doesn't really prevent someone from uploading an executable, it just prevents them from using certain extensions.

Have you tried setting a breakpoint and stepping threough to determine what the real error is? Its just that "Page cannot be displayed" is the generic error that is shown in the browser and provides no information for somebody trying to help you with this issue.

ya i got VS2005 here and I'm in debug mode but it's not stopping anywhere, I have break points at the top of Submit1_ServerClick which is what the upload button calls when it is pressed. This issue is only happening on exe files and exe files that have been renamed to other extentions. I'm guessing that something is looking at the file properties or file headers?
The strange thing is that it happens with all exe's, but not all exe's that have had their file extention changed.
so like:
iata76_enu.exe breaks page
iata76_enu.cheese breaks page
Silverlight.1.0.exe uploads fine
Silverlight.1.0.cheese uploads fine
NOTEPAD.EXE uploads fine
NOTEPAD.CHEESE uploads fine
Only reason I have that iata76_enu.exe is cause I was helping my coworker, otherwise I would never have run into this issue while testing the page.

Ah then its obvious...nothing to do with exe and everything to do with filesize.
I'm willing to bet that iata76_enu.exe is substantially larger in filesize than notepad.exe

we have a winner, the thing dies if you try to upload a file greater than 5mb, but the strange thing is that this is not caught by the VS2005 debugger. I'll fiddle with it and see if I can check the file size once the openfile dialog is closed and before the user hit's the upload button :P
thanks again guys

If I use the external utility to encrypt the connection string in web.config, will .net automatically know how to decrypt it when I build table adapters and such?

No
You will have to programaticly decrypt connection string before opening database.
Why do you want to encrypt it?
If ISS is normaly configured, you cant get Web.config.
PS: You cant decrypt one way encriptions (Hash) like md5.

It means that unothorized persons can't get web.config via browsers.

If so, then stay away from one way encryptions.

Evidently, that doesn't matter if IIS can be hacked and a remote user can gain access to the server.
