[SOLVED] Application Error, do debug

The font settings I found are:

My code
lblControlTitle.Font = new System.Drawing.Font(“Tahoma”, (float)11.00, System.Drawing.FontStyle.Bold);
lblControlTitle.Font = new System.Drawing.Font(“Tahoma”, (float)11.00, System.Drawing.FontStyle.Regular);

From Designer code
this.lnkSearch.Font = new System.Drawing.Font(“Microsoft Sans Serif”, 9F, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, ((byte)(161)));

It looks like it was related to an unexpected font setting. Could you check your Font = new Font() assignments and maybe send me some samples of the font settings to see what we had missed?

Hi Luca!

Yes! It is fixed! Thank you very much!

And I just saw in my browser part of my Visual WebGui solution converted to Wisej ! I think I have to work on the looks now, cause the “Vista” theme I was using was very Windows-Desktop-application-like and it look way different now! But it is promising!

Thanks again.
Alex

Please try the update just posted.

Best,

Luca

Hi Luca, thanks for your answer.

Please keep in mind that I have not played with Themes/Builder at all. So I don’t know if my exception is related to yours, although you said it is “similar”.

Best regards,
Alex

Yes, thank you. I was just about to write that we have a similar exception in Theme Builder and it’s caused by shared code. Should be fixed shortly. I will post the list of fixes soon.

Hi Luca,

I’m sorry, I can’t send the code, it’s rather complicated depending on other projects etc. However, I made some progress: I had the “Just My Code” enabled, so exceptions coming from outside my code were ignored. Now that I disabled that, I get a NullReferenceException at Wisej.Core.dll, but then the debugger is trying to find the Wisej.Core.pdb file which is not present.  Below, I attach the Call Stack.

Best regards,

Alex

If VS doesn’t break at the exception it probably means it’s not attached to the IIS instance in debug mode. When the “break on throw” option is on you should get a bunch of exception on startup:

A first chance exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll
Additional information: Access to the path 'C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\~AspAccessCheck_643d3c3211712.tmp' is denied.

Enabling the JavaScript break works only if you are debugging using IE and have enabled “Script” in Debug->Attach to Process. However, VS cannot debug both .NET and Script.

Can you send the test case?

Hi Luca,

Thanks for this new (to me) feature of Visual Studio, I had never seen that before!

Unfortunately, checking the CLR exceptions (in fact I also checked the Javascript exceptions later) did not make any difference. I keep getting in the browser  the attached as image. When I click either od the two buttons (the OK and the smaller empty one) I go to a blank browser….

Actually I cannot attach it, I get a “forbidden” error… Oh, well … It looks something like

Application Error                                                                              small Empty button
Object reference not set to an instance of an object.
OK button

Best regards,

Alex

Hi Alex,

To  make VS break when the exception is thrown:

• VS2015 – Debug->Windows->Exception settings. Check the “Common Language Runtime Exceptions”. You will start getting breaks whenever handled and unhandled exceptions occur. You can enable only the NullObjectException if you want to. In a web app all exceptions are handled to be able to give feedback to the browser.
• VS2013 – Debug->Exceptions. Same as VS2015

The settings are saved with the project user settings.

Best,

Luca
