CTaskDialog::LoadCommandControls
Adds command button controls by using data from the string table.
void LoadCommandControls(
int nIDCommandControlsFirst,
int nIDCommandControlsLast
);
Parameters
[in] nIDCommandControlsFirst
The string ID of the first command.[in] nIDCommandControlsLast
The string ID of the last command.
Remarks
This method creates command button controls by using data from the resource file of your application. The string table in the resource file has several strings with associated string IDs. New command button controls added by using this method use the string for the control's caption and the string ID for the control's ID. The range of strings selected is provided by nIDCommandControlsFirst and nCommandControlsLast, inclusive. If there is an empty entry in the range, the method does not add a command button control for that entry.
By default, new command button controls are enabled and do not require elevation.
Example
// TODO: Replace the strings below with the appropriate message,
// main instruction, and dialog title.
CString message("This is an important message to the user.");
CString mainInstruction("Important!\nPlease read!");
CString title("Alert Dialog");
CTaskDialog taskDialog(message, mainInstruction, title,
TDCBF_YES_BUTTON | TDCBF_NO_BUTTON | TDCBF_CANCEL_BUTTON );
taskDialog.AddCommandControl(201, L"First command button control");
taskDialog.AddCommandControl(202, L"Second command button control");
taskDialog.AddCommandControl(203, L"Third command button control");
// Show the CTaskDialog and remember how the user closed it.
int selection = taskDialog.DoModal();
switch(selection)
{
case 201:
// TODO: Place processing here for the first
// command button control.
break;
case 202:
// TODO: Place processing here for the second
// command button control.
break;
case 203:
// TODO: Place processing here for the third
// command button control.
break;
default:
break;
}
// Remove all the command controls so that we can use the same task
// dialog with new command button controls.
taskDialog.RemoveAllCommandControls();
taskDialog.AddCommandControl(301,
L"New first command button control");
taskDialog.AddCommandControl(302,
L"New second command button control should require elevation",
TRUE, TRUE);
taskDialog.AddCommandControl(303,
L"New third command button control should be disabled");
// Change the default command button control
taskDialog.SetDefaultCommandControl(302);
// Make sure the third option is disabled.
if (taskDialog.IsCommandControlEnabled(303))
{
taskDialog.SetCommandControlOptions(303, FALSE);
}
taskDialog.DoModal();
switch(taskDialog.GetSelectedCommandControlID())
{
case 301:
// TODO: Place processing here for new first
// command button control.
break;
case 302:
// TODO: Place processing here for new second
// command button control.
break;
case 303:
// TODO: Place processing here for the new third
// command button control.
break;
default:
break;
}
// Remove all the command button controls and add new ones from
// the string table resource.
taskDialog.RemoveAllCommandControls();
