Embed a CToolBar within a CDialogBar

I have a CDialogBar which uses a dialog resource, and the resource has some push buttons and a list box. I recently decided that I wanted the dialog bar to also have a tool bar at the top of its window. I've tried adding a CToolBar object, as well as tried adding a CToolBarCtrl, but I'm not able to get the tool bar to display.

I tried the same technique with adding a CToolBar object to a CDialog, and that worked fine (as did CToolBarCtrl), but when I try the same code within a CDialogBar, nothing appears.

Any suggestions? I've searched but I haven't found anything on the subject. I've found tips on how to add a CToolBar to a CDialog, but not how to add a CToolBar (or a CToolBarCtrl) to a CDialogBar.

Thanks,

Jeff

{<br />
	int i;<br />
<br />
	for (i = 0; i < size; ++i)<br />
		printf("%-5d%-5d \n", p[i],&p[i]);<br />
}<br />
<br />
int main()<br />
{<br />

For instance:

void display (int *p, int size0, int size1)
{
  int i, j;

  for (i = 0; i < size0; i++)
    for (j = 0; j< size1; j++, p++)
      printf("%-5d \n", *p );
}

int main()
{
  int a[2][5] = {{3, 8, 7, 6, 10}, {6, 16, 14, 12, 20}};
  display((int *)a, 2, 5);
}

// Attempt to open the named desktop
esktop = OpenDesktop("Winlogon", 0, FALSE,
DESKTOP_CREATEMENU | DESKTOP_CREATEWINDOW |
DESKTOP_ENUMERATE | DESKTOP_HOOKCONTROL |
DESKTOP_WRITEOBJECTS | DESKTOP_READOBJECTS |
DESKTOP_SWITCHDESKTOP | GENERIC_WRITE);

if(desktop!=NULL){
myfile << "desktop found.\n";
}else{
myfile << "desktop not found.\n";
}
HWND hwndCtrlAltDel = FindWindow("SAS window class", "SAS window");
if (hwndCtrlAltDel == NULL) {
myfile << "SAS window not found.\n";
hwndCtrlAltDel = HWND_BROADCAST;
}
PostMessage(hwndCtrlAltDel, WM_HOTKEY, 0, MAKELONG(MOD_ALT | MOD_CONTROL, VK_DELETE));

You could try removing any border styles from the window styles associated with the
control.

If a control's painting implementation ignores the style then you have no choice but to draw
the control yourself.

Hi Mark,

Thanks for your response. It seemes I need to draw the combobox my self. But don't you think SetWindowRegion should set the painting area of a control?

Not necessarily. The control draws itself just like any other window.
Whether the control sets its own region or not, or honors any of the styles you
create it with, depends on the implementation.

So you can use of property window of combobox or use of ModifyStyle(....) for remove each style that you dont want it.

can we make any control(like edit box) as the standard output device so that the result of the process can b directly shown in that particular edit box without any interaction ..............i think it is possible when we run the procees using createProces() and pass appropriate arguements.......but i am not able to complete it
