CTaskDialog::LoadRadioButtons

Adds radio button controls by using data from the string table.

void LoadRadioButtons(
   int nIDRadioButtonsFirst,
   int nIDRadioButtonsLast
);

Parameters

  • [in] nIDRadioButtonsFirst
    The string ID of the first radio button.

  • [in] nIDRadioButtonsLast
    The string ID of the last radio button.

Remarks

This method creates radio buttons 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 radio buttons added by using this method use the string for the radio button's caption and the string ID for the radio button's ID. The range of strings selected is provided by nIDRadioButtonsFirst and nRadioButtonsLast, inclusive. If there is an empty entry in the range, the method does not add a radio button for that entry.

By default, new radio buttons are enabled.

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.AddRadioButton(201, L"First option");
taskDialog.AddRadioButton(202, L"Second option");
taskDialog.AddRadioButton(203, L"Third option");

taskDialog.DoModal();
int selection = taskDialog.GetSelectedRadioButtonID();

switch(selection)
{
case 201:
    // TODO: Place processing here for the first  
    // radio button. 
    break;

case 202:
    // TODO: Place processing here for the second  
    // radio button. 
    break;

case 203:
    // TODO: Place processing here for the third  
    // radio button. 
    break;

default:
    break;
}

// Remove all the radio buttons so that we can use the same task 
// dialog with new radio buttons.
taskDialog.RemoveAllRadioButtons();

taskDialog.AddRadioButton(301, L"New first option");
taskDialog.AddRadioButton(302, L"New second option");
taskDialog.AddRadioButton(303, 
    L"New third option should be disabled");

// Change the default radio button to the second option
taskDialog.SetDefaultRadioButton(302);

// Make sure the third option is disabled. 
if (taskDialog.IsRadioButtonEnabled(303))
{
    taskDialog.SetRadioButtonOptions(303, FALSE);
}

taskDialog.DoModal();
selection = taskDialog.GetSelectedRadioButtonID();

switch(taskDialog.GetSelectedRadioButtonID())
{
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 radio button controls and add new ones from 
// the string table resource.
taskDialog.RemoveAllRadioButtons();
taskDialog.LoadRadioButtons(1001, 1005);
