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.

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?

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.

Re: OnClose function problem

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.

One simple solution (I think) would be

1. Write the status as STARTED to a status file when the application starts
2. Update it to CLOSED when application exits

You can check this status file to ensure whether the application closed normally or not.

One thing is that, when an application crashes no OnClose() like functions are called. Actually the OS is terminating the process.

You cannot do this for a single window.
Title bar size is a global setting which will effect all windows.

For your requirement you will have to do some skinning like custom drawing on the dialog and handle the WM_NCHITTEST message.

What I meant is all Windows on the system.
SystemParametersInfo is also used for system-wide settings.

ya i tried like this..

NONCLIENTMETRICS n;
n.cbSize = sizeof( NONCLIENTMETRICS );
::SystemParametersInfo( SPI_GETNONCLIENTMETRICS, sizeof(NONCLIENTMETRICS) , &n , 0);
n.iCaptionHeight = 28;//where as default value is 25...
::SystemParametersInfo( SPI_SETNONCLIENTMETRICS, sizeof(NONCLIENTMETRICS) , &n , SPIF_SENDCHANGE);

it was increasing but when i revert iCaptionHeight to 25...im able to see the change titlebar but captions in the registry were looking weired...so pls let me know if there is any possibility to change the titlebar only in my application
