The following styles generate buttons containing images or icons:

• BS_ICON

• BS_MINIICON

• BS_BITMAP

Where text is to be combined with an image, BS_TEXT is selected. To display an icon (#define ICON_ID 300) with the words "My button", the button text string is set to "#300\tMy button". Notice that "\t" is used to separate text from the image ID.

The following code example creates a customized button with text.

// presparm.c  -- demonstrates presentation parameters//                creates a button as a child window
//                and sets its text color
