Hi there, I have a little problem with a combobox and I don't get it ^^ There's a combobox which is filled with a list of some printers, not SESSION:GET-PRINTERS(), just a comma-separated string, e.g. "printer01,printer02,printer03,printer04,printer05,printer06,printer07,printer08,printer09,\\server\printer01,\\server\printer02,\\server\printer03,\\server\printer04,\\server\printer05,\\server\printer06,\\server\printer07,\\server\printer08,\\server\printer09" All I want to do is to remove the network-printers. Code (progress): DO iCntr = 1 TO NUM-ENTRIES(cbPrinterList:LIST-ITEMS, ',':U): IF SUBSTRING(ENTRY(iCntr,cbPrinterList:LIST-ITEMS,',':U),1,2) = '~\\':U THEN cbPrinterList:DELETE(ENTRY(iCntr,cbPrinterList:LIST-ITEMS,',':U)). END. This works only for each second (?) network-printer in this list. If I run this a second time, each network-printer is removed. But I don't want to run this twice. I'm pretty sure that it must be something with the backslashs (also tried with CHR(92)). Thx in advance..... PS: Progress 11.3.3 and Windows environment.
