Thread: Dialog LB output problems.

I am trying to get output to a list box in my dialog working.

Here is an example of the function I am using.
SendMessage(GetDlgItem( hChildHandle, IDC_SESSIONS ),LB_ADDSTRING,0,(LPARAM)szText);

hChildHandle is equal to my main window handle
do I need a seperate handle for my dialog, if so how do I get it.

Little confused about handles.

That didn't work.
Here is the code for my output function.
note I am sending main_window_handl,szstring to the function

Code:

void vShowText(HWND	hChildHandle, char *szText)
{
	int Line;
	

	// add string to the listbox
	SendMessage(GetDlgItem( hChildHandle, IDC_SESSIONS ),LB_ADDSTRING,(WPARAM)strlen(szText),(LPARAM)szText);
	
	// determine number of items in listbox
	Line = SendMessage(GetDlgItem( hChildHandle, IDC_SESSIONS ),LB_GETCOUNT,0,0);
	
	// flag last item as the selected item, to scroll listbox down
	SendMessage(GetDlgItem( hChildHandle, IDC_SESSIONS ),LB_SETCURSEL,Line-1,0);
	
	// unflag all items to eliminate negative highlite
	SendMessage(GetDlgItem( hChildHandle, IDC_SESSIONS ),LB_SETCURSEL,-1,0);
	EnableWindow(GetDlgItem(hChildHandle, IDC_SESSIONS ), FALSE );

}

it was the handle that was the main problem
I set up a global variable for hDlg then initialized it in the init section of the dialog call back procedure
then I changed all the function calls to reflect the new handle

presto it works (except for my send message button lol but I'll work on that)
