Heya i want to use ShowWindow(hWnd, SW_HIDE); to hide some application,
The problem is that the code i wrote works perfectly for any application except the one i need it for
heres the code
it does execute the line "ShowWindow(hWnd, SW_HIDE);" but it has no affect on the application, while if i put "SW_MAXIMIZE" , "SW_MINIMIZE" or any other "SW_***" it works perfectly and does manipulation on the application window,
Any idea why SW_HIDE does not work while all other SW_*** works?
Thanks Ahead....

Try calling ShowWindow twice, according to MSDN the second parameter to ShowWindow() might get ignored the first time it is called. I don't know if it will work, but its worth a try.
HWND hWnd = FindWindow(NULL, sName);
if(hWnd)
{
ShowWindow(hWnd, SW_HIDE);
ShowWindow(hWnd, SW_HIDE);

Does it happens with all the Windows or with any specefic Window ?
Are you trying to hide any window which you have created or any other applciaiton's Window ?

The WM_SHOWWINDOW message is sent to a window when the window is about to be hidden or shown.
I suspect the window you are trying to hide processes this message and prevents itself from hiding.
You might use Spy++ to see wheather or not this notification is send to the target Window.

No. Did you read the link I posted? MSDN says the first time ShowWindow is called SW_HIDE might be ignored. After that SW_HIDE parameter is honored.

Hi again... I found the solution...
1)This phenomenon happens with only one specific window...
2)To force this window to hide I do need call the "ShowWindow(hWnd, SW_HIDE);" Twice in the following way:
I could call twice the myClass::FocusP(str); twice, but i prefered to split it... looks better IMO
Thx 4 the help Ancient Dragon and others...

ShowWindow(hWnd, SW_MINIMIZE);
