Hi. Why the clone function doesn't change pixelformat when cloning the whole image?
When I have loaded bitmap that is 256x256 and has 8bpp, the new image that is written in bitmap2 object has still 8 bpp:
Bitmap * bitmap2 ;
bitmap2 = bitmap->Clone(0, 0, 256, 256, PixelFormat16bppRGB555 ) ;
But when I'll try to clone some part of it, lets say 255x256 or 256x255 the new PixelFormat of image saved in bitmap2 is 16bpp.
Why is that ?
How can I change the format of pixels not using Bitmap::ConvertFormat() function which is not included in GDI+ 1.0.

The system automatically creates a message queue for each thread. If the thread creates one or more windows, a message loop must be provided; this message loop retrieves messages from the thread's message queue and dispatches them to the appropriate window procedures
You create a message loop by using the GetMessage and DispatchMessage functions.
// Start the message loop.
while( (bRet = GetMessage( &msg, NULL, 0, 0 )) != 0)
{
if (bRet == -1){
// handle the error and possibly exit
}
else{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
} // Return the exit code to the system.
return msg.wParam;
The DispatchMessage function dispatches a message to a window procedure. It is typically used to dispatch a message retrieved by the GetMessage function

Try this..
HANDLE hStdout;<br />
SMALL_RECT srctReadRect; <br />
CHAR_INFO chiBuffer[160];
COORD coordBufSize; <br />
COORD coordBufCoord;<br />
<br />
<br />
hStdout = GetStdHandle(STD_OUTPUT_HANDLE); <br />
<br />
if (hStdout == INVALID_HANDLE_VALUE )<br />
{<br />
}<br />
<br />
<br />
srctReadRect.Top = 0;
srctReadRect.Left = 0; <br />
srctReadRect.Bottom = 1;
srctReadRect.Right = 79; <br />
<br />
<br />
coordBufSize.Y = 2; <br />
coordBufSize.X = 80; <br />
<br />
<br />
coordBufCoord.X = 0; <br />
coordBufCoord.Y = 0; <br />
<br />
<br />
fSuccess = ReadConsoleOutput( <br />
hStdout,
chiBuffer,
coordBufSize,
coordBufCoord,
&srctReadRect);
if (! fSuccess) <br />
{<br />
printf("ReadConsoleOutput (%d)\n", GetLastError()); <br />
return;<br />
}
Now create a File and write the Buffer into it

Hello people,
In my application I use ShellExecute to start a consoleapplication for certain actions. The problem is that the console-application starts up in the foreground.
My application is full-screen, and I don^t want the user to be bothered with the popping up of the console application. Is there any way to start the console application in the background (behind my application) ?
Thanks for any help,
Davy

The last parameter of the ShellExecute nShowCmd set to SW_HIDE
Knock out 'T' from CAN'T ,

Yes, SheelExecute prototype is:
HINSTANCE ShellExecute(
HWND hwnd,
LPCTSTR lpOperation,
LPCTSTR lpFile,
LPCTSTR lpParameters,
LPCTSTR lpDirectory,
INT nShowCmd
);
and the last aprameter can take following values:
SW_HIDE Hides the window and activates another window.
SW_MAXIMIZE Maximizes the specified window.
SW_MINIMIZE Minimizes the specified window and activates the next top-level window in the z-order.
SW_RESTORE Activates and displays the window. If the window is minimized or maximized, Windows restores it to its original size and position. An application should specify this flag when restoring a minimized window.
SW_SHOW Activates the window and displays it in its current size and position.
SW_SHOWDEFAULT Sets the show state based on the SW_ flag specified in theSTARTUPINFO structure passed to theCreateProcess function by the program that started the application. An application should callShowWindow with this flag to set the initial show state of its main window.
SW_SHOWMAXIMIZED Activates the window and displays it as a maximized window.
SW_SHOWMINIMIZED Activates the window and displays it as a minimized window.
SW_SHOWMINNOACTIVE Displays the window as a minimized window. The active window remains active.
SW_SHOWNA Displays the window in its current state. The active window remains active.
SW_SHOWNOACTIVATE Displays a window in its most recent size and position. The active window remains active.
SW_SHOWNORMAL Activates and displays a window. If the window is minimized or maximized, Windows restores it to its original size and position. An application should specify this flag when displaying the window for the first time
One of these should do the trick.

Thanks for the quick reply.
SW_HIDE doesn`t do the trick unfortunatly, I had allready tried that. But I`ll try with the one of the other options you suggested. one of 'em should get the job done...

Try CreateProcess[^]
Hope it helps
The statement below is true. The statement above is false.

First Tell me Which wrapper class are you using, secondly you can pass the name of doc file itself instead of passing the folder name while creating zip file!
