du kannst ShowWindow verwenden. Hier haste nochmal ein Auszug aus der PSDK:

Zitat:
The ShowWindow function sets the specified window's show state.

Syntax

BOOL ShowWindow( HWND hWnd,
int nCmdShow
);

Parameters

hWnd
[in] Handle to the window.
nCmdShow
[in] Specifies how the window is to be shown. This parameter is ignored the first time an application calls ShowWindow, if the program that launched the application provides a STARTUPINFO structure. Otherwise, the first time ShowWindow is called, the value should be the value obtained by the WinMain function in its nCmdShow parameter. In subsequent calls, this parameter can be one of the following values.
SW_FORCEMINIMIZE
Windows 2000/XP: Minimizes a window, even if the thread that owns the window is hung. This flag should only be used when minimizing windows from a different thread.
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, the system 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_ value specified in the STARTUPINFO structure passed to the CreateProcess function by the program that started the application.
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. This value is similar to SW_SHOWMINIMIZED, except the window is not activated.
SW_SHOWNA
Displays the window in its current size and position. This value is similar to SW_SHOW, except the window is not activated.
SW_SHOWNOACTIVATE
Displays a window in its most recent size and position. This value is similar to SW_SHOWNORMAL, except the window is not actived.
SW_SHOWNORMAL
Activates and displays a window. If the window is minimized or maximized, the system restores it to its original size and position. An application should specify this flag when displaying the window for the first time.

Return Value

If the window was previously visible, the return value is nonzero.

If the window was previously hidden, the return value is zero.

Aber dank DeCodeGuru haben wir das vollständige PSDK (inkl. aller Definitionen und Beschreibungen) auch bald in AUQ.de. :wink:

du meinst, weil ich zu sämtlichen Funktionen einen Auszug aus der PSDK poste? Ist doch nicht schlecht. Dann haben andere User wenigstens Zugriff auf die Infos aus der PSDK, wenn sie sie nicht runtergeladen haben. :mrgreen:

Auf der anderen Seite postet Microsoft die Erklärungen ja auch online im MSDN. Ausreichend wäre also bereits:

ja schon, aber ich finde es besser, wenn man möglichst viele Infos direkt im Forum findet.

@DeCodeGuru:
Ich hoffe du aktualisierts deine Zitate aus dem MSDN/PSDK auch regelmäßig. :wink:
