Grid Control in CFormView

markkuk

I'm trying to use the grid control in a CFormView-based class, by inserting a custom control in the dialog. My application fails with "Failed to create empty document" message at startup, the trace information from a debug run is as follows:

WndProc: hwnd=0x4C03D6, msg = WM_GETMINMAXINFO (0x0000, 0x0012F9FC)

Warning: Window creation failed: GetLastError returns 0x00000000

Warning: CDocTemplate couldn't create a frame.
The thread 0x4C4 has exited with code 0 (0x0).
The program 'D:\TEMP\gctest\Debug\gctest.exe' has exited with code 0 (0x0).

The first warning is caused by ::CreateDialogIndirect() failing when the CMainFrame is being created. Then everything else fails because there is no main window.

Any idea why the window creation fails? Is some additional initialization needed?

hi..if u wanna use gridcontrol... use active X.....Add dbgrid control and ado to your project......assign ado topo a recordsource......\ Set SQL in ado... Call the the id of ado from the dbgrid control......Add table and recordset u wanna call in dbgrid..... These thing can be done in resource workshop that is in something.rc file....No need to code anything in the CMainFrm...... Ur problem occurs becoz another program might have running the recorsource at the sametime.... "LIFE IS AN ADVENTURE THAT SHOULD BE LIVED.... LOVE IS A PROBLEM THAT SHOULD SOLVED...LOVE YOUR LIFE!!"

I guess I should have specified that I am trying to use Chris Maunder's MFC Grid Control 2.22, not an ActiveX component. I need a control with checkboxes and date pickers as cells.

Anyway, I solved the first problem myself, I had to include a member variable for the control in the view class (not mentioned in the documentation). But the control still doesn't work, in fact it doesn't appear at all on the dialog. Debugging shows that the control's Create() function isn't called.

Isn't the MFC framework supposed to Create() all the controls defined in the dialog template? If I must Create() the control myself, how do I access the control position and size information defined in the dialog editor?

Try EasyGrid ActiveX as a substitute. It must will be very helpful. Download is available @ http://www.share2.com/easygrid/ :cool:
