Hi,

Set the WS_EX_TOOLWINDOW style bit.

Where in the code do I add the WS_EX_TOOLWINDOW bit?
And will this always prevent the application appearing on task bar?

Thanks
Neil

When the window is being created (probably be calling Create) include the WS_EX_TOOLWINDOW style and it will always hide the taskbar 'bar'.

It works now.

I done the following:

BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
cs.style |= WS_EX_TOOLWINDOW;
if (!CFrameWnd::PreCreateWindow(cs))
return FALSE;

return TRUE;
}

but still the application appears in the task bar at the bottom of the screen.

Have a look at:

and

Hope they help.

WS_EX_TOOLWINDOW is an extended window style. You need to include it in the dwExStyle field, not the style field.

Hope this helps,

Hello,

how can one detect if file and/or printer sharing is enabled?

I've found a key in the registry but I assume there is also a Windows API function?

Confused | :confused:

-Dominik

_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

Depends. If you have a console application with "main" you can just parse all argc elements in the argv array.

If you write a windows executable you can parse the LPSTR lpCmdLine parameter in WinMain.

If you don't have access to the WinMain function you can use the API function LPTSTR GetCommandLine(VOID) to get a pointer to the parameter string.

Or you can use this class: http://www.codeproject.com/cpp/cmdlineparser.asp[^]

Hope that helps Big Grin | :-D

comma operator

how come the comma operator isnt used more often i was able to write a whole function using 1 semi color at the end so how come people dont use the commas?
is there a performance reason or somethting?

Dave Bryant19-Aug-03 16:44

Mainly because it makes it a lot harder to see what is going if the comma operator is used for anything more complicated than a fairly trivial statement. If you write a complex function in one line using the comma operator, and then come back to it 6 months or a year later, it would be considerably more difficult to understand what is going on, than if it were written clearly in multiple statements.

It is mainly useful in contexts where only a single statement is allowed - for example, in the increment statement of a for loop.

for ( int i = 0, j = 10 ; i < nCount ; ++i, --j ) {
// ...
}

Comma is used heavily in our code... while you declaring functions. For example:

void Foo(int iNumber<font size=7 face="Times New Roman">,</font> bool bFlag);
BOOL Move(HWND hWnd<font size=7 face="Times New Roman">,</font> LONG x<font size=7 face="Times New Roman">,</font> LONG y<font size=7 face="Times New Roman">,</font> ULONG cx<font size=7 face="Times New Roman">,</font> ULONG cy);

im talking about where semi colons are used
like this

void main() {
function(),
function2(),
function3();
}
