The following MFC code calls my own OnInitDialog function which in turn sets focus to my dialog window's first control and then returns a boolean value of FALSE. However, the focus is NOT set and tabbing fails when my dialog page appears. WHY?????? Is there a problem with MFC?
The focus setting works when a dialog in initiated via the MFC "DoModal()" command.
Thank you for your assistance.

Showing the MFC code doesn't really help us 
What are you doing in your derived class OnInitDialog? How are you setting focus to a control?

Mark:
Sorry about that.
Here's my app's function that's called by the MFC code. I'm adding my own supplementary comments.
BOOL CSetupDlgMyApp::OnInitDialog()
{
CDialog::OnInitDialog();
UpdateMyNames(); // updates class object parameters
GetDlgItem(IDC_RENAME_ACCOUNT)->SetFocus(); // Here I'm trying to set my dialog page's
// focus to its first control
return FALSE; // return TRUE unless you set the focus to a control
// EXCEPTION: OCX Property Pages should return FALSE
}
Thank you for your assistance.

Maybe try this instead:
//GetDlgItem(IDC_RENAME_ACCOUNT)->SetFocus(); // Here I'm trying to set my dialog page's
GotoDlgCtrl(GetDlgItem(IDC_RENAME_ACCOUNT));

Is IDC_RENAME_ACCOUNT the first non-static control in the dialog's z-order?

Yes, it is.

Then there's no need to call SetFocus() or return FALSE.

Focus is being set to the first control upon dialog activation and initialization; however, tabbing is inoperative until one touches the first control to activate the subdialog. After the subdialog is opened and closed, tabbing works on the dialog controls.
Although tab controls and ordering are set in the MFC resource editor, why is tabbing not working and inoperative upon dialog window initialization and activation?
(Note that the window display occurs on a touch panel screen whereby the touching of a button is handled like a LEFT MOUSE DOWN\UP command.)
Thank you for your assistance.

Hi,
I am trying to use this function
<br />
CWnd::FlashWindowEx()<br />
in my CMainFrm class but it cannot compile returning the error
error C2065: 'FlashWindowEx' : undeclared identifier
However, if I use
<br />
CWnd::FlashWindow()<br />
It is ok. Does anyone know why the call to CWnd::FlashWindow() does not work ?
Thanks.
ps I have ommitted the arguements in this post.

Maybe you have an old version of MFC (for instance, VS6 MFC doesn't have the CWnd::FlashWindowEx method while it has the CWnd::FlashWindow one). As workaround, try to use the Win32 FlashWindowEx function.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

can anyone show me how to read from a text file i have opened and written to using cfile.
eg this is how i opened and wrote to the file.Check1 is a boolean variable.i would like to retrieve the value of that boolean variable.
CFile LoggingObject;
CString txt;
txt.Format("%d", check1);
LoggingObject.Open( "c:\\test.txt", CFile::modeCreate|CFile::modeReadWrite);
LoggingObject.Write (txt,sizeof(txt));
|

Since you knew how to use the Write() method, I'm surprised that you overlooked the Read() method.
sivern wrote: LoggingObject.Write (txt,sizeof(txt));
This should be:
LoggingObject.Write(txt, txt.GetLength()); Or:
LoggingObject.Write(&check1, sizeof(int));

I,m not sure if this is the right place to ask, but...
I use:
<br />
#include <atlbase.h><br />
#include <atlcom.h><br />
in my code , and keep getting err message on building:
"error C2065: '_Module' : undeclared identifier". '_Module' is in ATLCOM.H folder.
Thanks for help in advance!

Have you tried:
#include <atlbase.h>
extern CComModule _Module;
#include <atlcom.h>

hi guys,i am trying a 3-D dynamic array in C.i know how to do it for 2-D but i dont konw what i am missing to do it properly for 3-D
say h*w are the size of a matrix
int **matrix=NULL;
matrix=malloc(h*sizeof(int));
for(i=0;i

ovoundaga wrote: matrix=malloc(h*sizeof(int));
Actually it should be
matrix = malloc(h * sizeof( int * ))
Anyway, the overall process you posted it is correct, hence
int m, n, o;
int h, w, k;
h=3; w=5; k=7;
int *** pppInt ;
pppInt = (int ***) malloc(h*sizeof(int **));
for (m=0; m<h; m++)
{
pppInt[m]= (int**) malloc(w*sizeof(int*));
for (n=0;n<w;n++)
{
pppInt[m][n]=(int*) malloc(k*sizeof(int));
}
}
for (m=0;m<h;m++)
{
for (n=0;n<w; n++)
{
for (o=0;o<k; o++)
{
pppInt[m][n][o]=rand();
}
}
}
