hello, how are you all, I need to help me with this I have an application sales works well, but now I'm installing where a client and has readers barcodes symbol STB4278 these readers do not give automatic return after reading the code, I encode something in the InteractiveChange of control, but I have problems because I just read the code of the size you specify will

if isdigit(alltrim(this.value)) and len(alltrim(this.value))>=9 AND setup.lenterfact
	keyboard '{ENTER}'
endif

in this case only reads the code that has 9 digits, if you have more or less does not read correctly
