Open the dialog template on which the combo box is dropped.
Click on the button with the arrow pointing down.
Now adjust the size of the combo box by dragging with the mouse.

Or

Use CComboBox::SetMinVisibleItems[^]

But its saying like Widechartomultibyte cannot convert 5 parameter from BYTE[128] to LPSTR..

code:
WCHAR szstring[256];
length = lstrlen(szstring);
BYTE pByte[128];
WideCharToMultiByte(CP_ACP, 0, szstring, -1, pByte, length, NULL, NULL);

Can you please guide me where am i going wrong?

Thanks,
Rakesh.

The expected 5th parameter is char* and you're giving it an unsigned char*.
All you need to do is typecast pByte as (LPSTR)pByte.

You might look into the HKCU\Control Panel\Colors key. That's where the Advanced Appearance dialog stores its information.

OnClose function problem

Pryabu10-Aug-09 23:16

10-Aug-09 23:16

I created a exe named as test.exe.I want to put a log whether the exe is closed manually or by some other crash. If the exe gets crashed,will it call onclose function or how that exe will get closed?
How can i put a log during crash?

Thanks,

You cannot log the crash (of course OnClose isn't called when the application crashes). Anyway you may log the normal program execution in order to have hints about the crash.

Thanks. Then how that exe will get closed during crash? Whether it will call OnClose or OnDestroy function?

«_Superman_»10-Aug-09 23:38

You should call SetUnhandledExceptionFilter[^] to set a filter function to be called during a crash.

Suppose if i closed the application using task manager, the control is not coming to SetUnhandledExceptionFilter function.

David Crow11-Aug-09 3:12

Did you read the docs for that function:

After calling this function, if an exception occurs in a process that is not being debugged, and the exception makes it to the unhandled exception filter, that filter will call the exception filter function specified by the lpTopLevelExceptionFilter parameter.

As Task Manager likely uses something akin to TerminateProcess(), it's doubtful that both of the above conditions would evaluate to true, thus making SetUnhandledExceptionFilter() a moot point.
