How can I put a text in a string on the Panel?

[Ramles97]

I know this question sounds maybe somewhat basic. I cannot type anything in the string box that I have on the panel.

In the code there is only one line that calls the string box from the panel which is:

GetCtrlVal(sPanels.P_Hauptmenue,P_MAIN_Orderdata,cOrderdata);

Here are the settings of the box:

There is only this string box where we can put text in, but after compiling and starting the program nothing can be written in the box.

Thanks a lot in advance!

I just found the problem. it was this line:

SetCtrlAttribute (sPanels.P_Hauptmenue, P_MAIN_Orderdata, ATTR_MAX_ENTRY_LENGTH, scOrderdata);

  the ATTR_MAX_ENTRY_LENGTH (which is -1) made the typing of text in the string impossible.
