GetDlgItem
The GetDlgItem
function retrieves the handle of a control in the specified dialog box.
HWND
GetDlgItem(
|
HWND hDlg, |
// handle of dialog box |
|
int nIDDlgItem |
// identifier of control |
|
); |
|
Parameters
hDlg
Identifies
the dialog box that contains the control.
nIDDlgItem
Specifies the
identifier of the control to be retrieved.
Return Values
If the
function succeeds, the return value is the window handle of the given control.
If the
function fails, the return value is NULL, indicating an invalid dialog box
handle or a nonexistent control.
Remarks
You can use
the GetDlgItem function with any parent-child window pair, not just with
dialog boxes. As long as the hDlg parameter specifies a parent window
and the child window has a unique identifier (as specified by the hMenu
parameter in the CreateWindow or CreateWindowEx function that
created the child window), GetDlgItem returns a valid handle to the
child window.
