I am currently working on an VB.net program that handles an object defined in a COM dll.The problem is that sometimes that object causes a crash: an exception that cannot be handled with a 'Try Catch' is thrown and a dialog asking to debug with Visual Studio appears.
View 1 RepliesI have installed VS2008 in my machine. I made a small program in the VB. When I start debugging, the system responds by indicating that the program is running but I don't see any output. Is their a possibility that VS2008 debuggers woun't work with Windows XP Home Edition which comes with my laptop.
View 7 RepliesWhen you Debug.Print some object types in the Visual Studio 2010 debugger, the output includes a backtick. What does the backtick mean?
Dim myList as List = a List
Debug.Print(myList.GetType().ToString()
Output in Immediate Window debugger: System.Collections.Generic.List`1[System.String]
I was woking on a windows app today when my errors were no longer being displayed as they usually would, instead the debugger just jumps out of the method. It works in other projects, I have put this: 'Dim i as Integer = "A"' in as my first line to try and raise an error but it just exits the sub on that line.
The output window makes a note of the exception but the usual popup trace does not appear, any ideas how I get it back??
I'm currently using VS2008 and VB.NET.When I attempt to populate a Queue that has not been instantiated with objects, the program simply hangs without throwing an error.I have run into this issue multiple times in different parts of the program in the past few days.What could be the cause of this?
Here's the code:
Structure ConsoleBufferLine
Public EntryDate As Date

I'm running VS2010 4.0.30319 SP1. My WPF project runs once in the debugger, then won't run again unless I wait 30-60 seconds. I've found that in Task Manager, there is an associated vshost32.exe process that starts when I first load the project. It remainswhile the project is running, but exits when I close my app. After 30-60 seconds, the vshost32.exe reappears and I'm able to restart my app. But until vshost32.exe reappears, my app will not run.
View 14 RepliesI have a vb.net application that I compiled and all, I took the EXe and all and placed it on another pc that has only visual studio express on it.
When I open my .exe I get a message saying No debugger has been found, no Jit Debugger has been specified I can either select retry to find a debugger or click on cancel to forget about the debugger.
If I press cancel, my application launches correctly without any problem.
It seems like whenever i click my close button the application will close but the debugger is still in active.How to exit this debugger? :)

View 1 RepliesI have to develop an application using MS Visual Studio 2005 or above with the following objective:
* The application should allow users to create as many new forms as they want and each form should behave like a MS Visual Studio WinForm. By saying that it should be a container for drag and drop of controls from the toolbox that I will develop....
* Once the user design's each screen to his taste by placing various controls on the form, he should be able to save the form as a screen. Of course I have to provide functionality for each of the controls such as if he drags a button on to the form, he should be able to specify what action it has to perfom when clicked when the application is put into run mode. Quite similar to regular windows form button.
* My application should have two modes: a DESIGN MODE, where user can drag, drop controls and specify what they should do when put into RUN MODE. This is quite similar to MS Visual Studio designer.
* Last but not least is to be able to access the application via the browser with the same look and feel his desktop version.

View 1 RepliesWhen a custom class overrides the ToString() method, the C# IDE uses this function to display the class in the debug mode(tooltips, watcher etc) Does the VB.NET the same? I have impression that overriding ToString() method does change nothing. I mean, in the watcher I see Name myBusinessObjectInsnace Value {MyNamespace.myBusinessObjectInsnaceType}

View 4 RepliesI am very confused about the database type to be used in my vb.net application. I have been using SSCE database, but for that user has to download and install SSCE, which many of my users do not want. If I use Access, the security issue is very very serious.

It is a database application using SQL and Visual Basic 2005 from visual Studio.
I get an error Value cannot be null. Parameter name: context.When I get this error which accumulate 3 or 4 times in design mode, on an open form. some of the properties disappears for the textboxes like dock, buinding and so on. Does anyone knows what this error means.
I am trying to make a web application in VB.NET using Visual Studio 2008 that will accept login credentials and compare them with an Access database for authentication/validation. I found lots and lots of examples for how to do this with a Windows Form App, but none with a ASP.NET Web App. tried to modify the steps for a web app but I'm not sure how to make it work. The database connection is good and the query seems to work fine. Here's where I'm having trouble. In the tutorial, he says to use:
01 Private Sub But_Validate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles But_Validate.Click
02 Private Sub But_Validate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles But_Validate.Click
03 Dim r = Me.UsersTableAdapter1.ValidateUserNamePassword(Me.Txt_UserName.Text,Me.Txt_Password.Text)
[code]....
No matter what I put in for the username and password (as long as they are valid values) I always get a "success," never a failure. I know my query is working right because I put a gridview on the page and bound it to the result from the query; when I type in a user/pass that is not in the database the gridview is blank, when I type in a correct user/pass the gridview displays that row from the database.
I have put at least 4 hours in to figuring out why i cannot view my results when I run a datagrid in my 2010 visual studio WPF application.Also, it looks like it is only filling one record in the datagrid.

where the VS debugger refuses to show certain field types including dates.My call stack contains FunctionA which calls FunctionB. FunctionB has about 45 parameters and many of them are dates.When I step into functionA,
1. the debugger refuses to show a date variable when you hold the mouse over it. It just shows {Date} instead of a value
2. If you do quick watch on that same variable, it also just shows {Date} instead of a value
3. If I do ?variablename in the immediate window, I get "System Error &H80131c23&"
When I comment out the call to functionB, the date variables all show correctly in all the above methods. I will stress that the code has not yet reached functionB, just its very existence in code screws up the debugger.I'm thinking this is a memory issue and maybe vs debugger can't cope with a huge function stack frame dataspace.devenv is only using 268Meg of ram on a 2Meg box, with not much else running. Thats reasonable for this size of project.
I've been given an old VB.net 1.1, Visual Studio 2003, project.When debugging DateTime shows as #09:34:00 AM#, the date-part is hidden. I would like to see which date the DateTime is.I've tried to modify mcee_cs.dat, but that doesn't seem to do anything.

View 8 RepliesWe are designing a toolbar to be used in PowerShape that was originally written in VB6. We are beginning the conversion to VB.net and for some reason, when we size the new form that is the actual toolbar, we can see the size change in Design Mode but when we run the debugger it does NOT show the newly sized form. We managed to get the Width to update after clearing the Debug and Release directories but not the Height... And even then it only works once then we have to go back in and clear the directories again in order for the width to update.
View 1 RepliesAm experiencing a confusing situation where the debugging seems to skip arbitrary sections of code (including breakpoints) and then breaks on non-breakpointed lines. The call stack reports [External Code] even though its not external code
View 2 RepliesIm developing several applications under Visual Studio, and now have a real nightmare in hands. When i start to debug, VS hangs completely. Windows allows me to start task admin, and close the "devenv" process.I have serious problems here. I need to deliver my projects before the deadline!
Win 7 Pro 32 bits, VS 2010 SP1, running on HP computer based on Intel i5, 4gb ram. everything works as intended, except VS. When debug crashes, the devenv process uses about 25% of CPU and 250~400Mb of ram.
I have a program, I have published it, and I have been actually using it in my PC. Whenever it encounters an error, the JIT debugger comes out. How do I prevent it from popping up using try...catch blocks, or is there any other ways or code on how to do this?
