How are you using these CString variables?

CString strVarName;
CString strLine = <sometext>;

strVarName = strLine.Mid();

Aside from this, I see nothing strange. Have you compiled the project in Debug mode and started it via F5? If you have memory-related issues, they will show up in the debug output window.

taskbar title for MFC application

Hello!
I have a dialog based MFC application with "Style: Popup" and "Border: None". So the system menu, title bar, minimize box, maximize box are not displayed. Also the "Caption" edit is disabled. I want to set a title for the application to be displayed in the taskbar since with the above mentioned settings it only displays the icon.

How can I set the title?

Thanks,
Mircea

Multiple Views with Activex Controls

Hi,

I have to display a window with top pane displaying a richtext edit control and bottom one displaying msflexgrid.

I added two controls(rich text edit control and msflexigrid).
Created two views.
Added a variable(rich text) for the first view.
Added a variable(msflexigrid) for the second view.
In mainframe.cpp in oncreateclient
i created a static splitter and createdviews with the two views.

But none of the splitter window(view?) is displaying activex control.

What should i do.

Regards,

Take care of the z-order of the windows. The farther is "less" visible.

Thank you. It worked. But a small problem.
The top pane/view contains richtext edit control. on CSize of View function i added code to adjust richtext edit control position. This is working fine.

But the bottom pane/view contains msflexgrid. on CSize of View function i added code to adjust msflexigrid control position. This is not working i mean it is in the initial position of (0,0,0,0). What property of msflexigrid control should be set or is it the intended behaviour of msflexigrid control.

Regards

Try setting the AllowUserResizing property to flexResizeBoth.

Hi,

I don't now the number of columns in advance for a msflexigrid. How to compute the columns dynamically and pass to the function setcols.

GetCols() gives you the number of columns
SetCols() allows you to set the new number of columns
SetColPosition() is used to change the position of a column.

More about using the control you can get by reading this article here at CP:

windows CE, change display contrast

18-Oct-05 2:00

Hello!
i'm trying to change the contrast of my windows CE 4.2 device.
After some search on the net i found some methods to change the contrast,
all based on ExtEscape() function. Unfortunately ExtEscape always returns 0
on my device, no matter what escape code i pass to it.
This is a snapshot of my code:

bool SetContrast(int nParam)
{
ContrastCmdInputParm ContrastParm;
int rc, fQueryEsc;

fQueryEsc = CONTRASTCOMMAND;
HDC hdc= GetDC(NULL);
rc = ExtEscape (hdc, QUERYESCSUPPORT, sizeof (fQueryEsc),
(LPSTR)&fQueryEsc, 0, 0);
if (rc == 0) {
// No support, fail.
ReleaseDC (NULL, hdc);
return false;
}
ContrastParm.command = CONTRAST_CMD_SET;
ContrastParm.parm = nParam;
int nCode= ExtEscape(hdc, CONTRASTCOMMAND, sizeof(ContrastCmdInputParm),
(LPCSTR)&ContrastParm, 0, NULL);
ReleaseDC(NULL, hdc);
return (nCode > 0);
}

This function always fail with no support.

Can anyone help me?

Did you try WinDbg[^]? It's not very easy to use, it's a command line debugger, but it might offer you valuable clues to debug the problem.

How to change color of push button

You can handle the CWnd::OnCtlColor / WM_CTLCOLOR message in your dialog class, and return a brush of your choice.

Windows will then use that brush to paint the background of a control.

Do a search for OnCtlColor in msdn, and it will even give sample functions.

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vcmfc98/html/_mfc_cwnd.3a3a.onctlcolor.asp[^]

Good luck,

Iain.

You have to Create Owner Drawn Button PLUS Handle CButton::DrawItem(...)
