I didn't see this in any of the forums, so I am posting a new message.
I am trying to view a designer (UI) of a form in my project. The UI doesn't open and I get this error "The control System.Windows.Forms.TabControl has thrown an unhandled exception in the designer and has been disabled".
I haven't been able to find much seaching the web, Code Project or dnzone.com.
Anyone experience this problem before?

Many times. Easiest way to fix this is described here[^].

Thanks. I tried that. It says something about a file not being found, but doesn't tell me what its name is. How do I find that out?
|
|
|
|
|
If you did it correctly, the debugger should break when the file is not found. Simply investigate the line it's crashing on - what method call is failing, and what arguments are you passing to it?

Still didn't work as initially planned, but I was able to get some information out of the Visual Studio error message after clicking the Debug button.
FusionLog:

The MPSAPI.DLL is added as a reference so it must be something that DLL depends on.
Thanks for your help Judah.

Ok, the MPSAPI may be the problem. Are you calling into this MPSAPI dll in your constructor anywhere?

The other error I get when trying to open the UI is...
The control System.Windows.Forms.TabControl has thrown an unhandled exception in the designer and has been disabled.
I tried to included the snag-it capture of the message box, but it doesn't look like that can be done on this site.

I got it to work one time so far.
This is where it's failing to find a file....
~VideoWindow()
{
}
No arguments and no code.

Perhaps it's not important, but can I ask why you have an empty destructor in your C# code?
|

Can anyone link me to a good article/resource explaining how to marshall different data types, specifically from C++ to C#. I'm trying to marshall some stuff going to/from a DLL.
|

There are several articles on this site detailing how to do this. Basically, for standard exported C functions, you can use P/Invoke. If you're interesting in interoping with C++ classes things other than standard C exported functions, you'll probably want to write a wrapper for the C++ classes in C++/CLI, which can them be called natively by C#. (Again, check the articles on this site for info on C++/CLI interop with C#)

there seems to be some code to operate the registrykey(add a key in "HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run"),but how can I use these codes or where can I use them in the deployment project. and in the deployment project,there is also registry management in the deployment,can I set the attributes to implement the executing of the application when turning on the computer.

I think you answered your own question there... The Deployment project's registry editor.
|
|
|
|
|
I add a new item in HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\
CurrentVersion\Run,and then I add a key, and set the key value to the path of the application,can it work?
by the way how can I get the path of the application in the registry editor and write it to the keyvale?

Looking at the properties of the Application Folder in File System, the default location is probably something like this...
[ProgramFilesFolder][Manufacturer]\[ProductName]
which is equal to this...
[TARGETDIR]
I don't know of a way to get the EXE's name, but you should know what that is anyway. So add your reg string with a value like this...
[TARGETDIR]myExe.exe
|
|
|
|
|
"[TARGETDIR]" works!
I've been searching on the internet and msdn for a few days to solve the problem.Thank you for your guide!

Sure. I wish I could find a list of all the variables that are available, but those are the only 4 I'm aware of. That may be all of them.

Hi All
I would like to use a DLL written in C, in my .Net 2.0 win application.
I’ve tried using DllImport, but I’ve encountered the following exception:
“Attempted to read or write protected memory. This is often an indication that other memory is corrupt.”
Probably because I didn’t declare the function right.
The DLL function I’m trying to use is:
extern "C" __declspec(dllexport) void EncryptString(char* inString, int strSize, char* ret)
What should be the .Net equivalent?
Thanks in advance

stringbuilders are used to marshal strings that get changed by the unmanaged code..
try
<br />
[DllImport(@"YOUR.DLL")]<br />
public static extern void EncryptString(String inString , int strSize , System.Text.StringBuilder result);<br />
this is assuming the first parameter won't be changed.
