Limitations with Graphics & Sound Functions (Windows CE, Touch Panel Module )
The Sound VIs are supported only for targets with a sound device or sound card. NI-TPC hardware does not currently contain a sound device.
You can use events with picture controls.
The Beep VI ignores all input parameters because the VI calls the Windows CE MessageBeep function, which takes no parameters.
Pen Width and Style
If you set the width element of the pen input in the Picture Functions VIs to anything greater than 1, the pen style is solid regardless of the value of the Style element.
Showing Ampersands (&) Using the Draw Text VIs
You must include two & symbols in a string to display a single & in a picture control if you are using the Draw Text at Point or Draw Text in Rect VI.
