I'm not entirely sure, but I believe your problem may not be the PtSetArg, but instead the PtMultiTextModifyText. You 
provide the values start=-1, end=12, and insert=-1. Since start!=end, insert would be ignored and the text from position
 (start) to position (end) be replaced by the given text. In that operation, start==-1 could cause a failure.

What exactly are you trying to achieve with these argument values? Do you want to delete the MultiBox's first twelve 
characters and append your text to the end? That will take two calls, one for deleting and one for insertion.

You could also try to printf() the value of (text) and see if PtSetArg / PtGetResource really didn't work...

Cheers,
Thomas

Betreff: getting data from textbox

i i was trying to retrieve data from the textbox using the following code.
PtArg_t arg[1];
		char *text;
		PtSetArg ( &arg[0], Pt_ARG_TEXT_STRING, &text, 0);
		PtGetResources (ABW_PtText1,1,arg);

		PtMultiTextModifyText(ABW_PtMultiText1,-1,12,-1,text,12,NULL,NULL);

but the PtSetArg() function doesnt seem to work.

Are you sure you are targeting the correct text box in your application?
