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.
