my function f_my() receive identifier
of control, for example
IDC_DATETIMEPICKER1
How do set type of argument?
And how this function to call for execution?
As show - unproperly:
error C2660: 'GetDlgItem' : function does not take 1 arguments

void CADO_MDIApp:: f_my (long identifier)
{
COleDateTime* p1 = (COleDateTime*) GetDlgItem(identifier);
}

You are trying to call GetDlgItem() which resides in the global namespace (since CADO_MDIApp is not derived from CWnd). That version requires 2 arguments.

Why are you wanting to do this? The application object should not need to know about controls on a dialog.

Maybe an int.

GetDlgItem function takes actually 2 parameters [^]. Possibly you want to call CWnd::GetDlgItem method.

In addition to what the other said and to remind you what I told some hours ago, GetDlgItem returns a pointer to a CWnd derived object. COleDateTime doesn't inherit from CWnd, so it is a completely different object. So, you can't cast your control to a COleDateTime object and expect everything to work.
And as I said David, why are you delegating that stuff to your application class ? Your dialog class should be responsible to manipulate its control, the application class has nothing to do with that.

WTSVirtualChannelWrite fails, GetLastError returns ERROR_INVALID_FUNCTION

I've been trying to figure this one out for the past couple of days with no success Mad | :mad:

Here's the relevant code: http://pastebin.ca/1419150

I'm testing this on a Windows XP SP3 virtual machine. I connect to it using mstsc from a Windows Vista Ultimate x64 machine (which is also the host for the XP virtual machine). The program running on the RDP host (the XP machine) also opens two other virtual channels in much the same way and they work fine.

Any help is much appreciated Smile | :)

Sorry to wake this thread after 4 years, but did you find a solution to this problem?

I have a static virtual channel plugin, It works fine between Windows 7 machines, but when I run use an XP client, the server fails at WTSVirtualChannelWrite with "Incorrect function"

Please tell me if you found any clue!

Check whether you have permission(access rights) to move the files to remote machine...

Why not? Have you called GetLastError()?

Without seeing any of your code, I can only suggest one thing that will solve this - remove the errors from your code.

Oh - and work out what bit of your code is being executed when this error occurs (hint - look at the call-stack to determine that).

Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

I'm having the exact same problem.

I created a test program in Visual C++, and wrapped it with a licensing tool from Softkey.com, but when I run the executable, I get the error

dwwin.exe – Application Error
The exception Breakpoint
A breakpoint has been reached.
(0x80000003) occurred in the application at location 0x7c90120e.

Click on OK to terminate the program
Click on CANCEL to debug the program

The folks at Softwarekey.com don't know the answer. Microsoft suggested i disable Dr. Watson (http://support.microsoft.com/kb/188296/en-us), but that doesn't work.

Hi,

I want to list all applications that can be used to open a file based on the file extension.ie "Open With" list when we right click on a file in Windows Explorer. How windows manages this.

thanks

Well, what would you expect? Just provide it with a valid handle.

FYI - the doc page[^] contains an example as well.

HKEY hKey = GetRegistryKey(CString ("Connections") );

this has been successful as i have called RegEnumValue and thats working fine.

but problem is with RegQueryValueEx

int t= RegQueryValueEx( hKey, strValue, NULL, &Type,(LPBYTE)rgValue,&size1);
