Hallo,
thanks for all the work. I wanted to let everyone know of a problem I had with the display of a 25i barcode in barcode_test.au3.
It happened on a specific barcode i needed - the barcode in the label was incorrectly displayed - while printing etc all was OK. Finally I found that my barcode started with a "&" (ampersand). The complete barcode is 05185160121072706 (control character 0 not included). The string for the label is É&3T]-+ig]Ê but the barcode displayed was É3T]-+ig]Ê the ampersand dissapeared.
The solution was by defining the stile of the label with $SS_NOPREFIX. The hepltext for Label Styles says:
Prevents interpretation of any ampersand (&) characters in the control's text as accelerator prefix characters.
I added the style to the label definition and now the barcode was displayed correctly
$barcode = GUICtrlCreateLabel("", 10, 39, 580, 130,$SS_NOPREFIX)
I hope someone finds this useful
