Par2: How to select a printer device with ABC's EIP
2012-05-10 -- Russ Eggen
 
its actually pretty easy. Here is how its done: 1) For the column that stores the device name, Use any dialog lookup from the drop list. Font, Color, File, etc. Does not really matter which. I used File. 2) You will need to override the TakeEvent method in the parent class, but not by editing it. Two embeds in this method: A) Declare local variable (DATA embed): Str CSTRING(FILE:MaxFilePath+1),AUTO B) The code, before parent call: CASE Event OF EVENT:DroppingDown IF ~SELF.ReadOnly IF NOT SELF.Title SELF.Title = SELF.ListBoxFeq{PROPLIST:Header,SELF.FieldNo} END UPDATE(SELF.FEQ) Str = SELF.UseVar IF PrinterDialog(SELF.Title) !Key code Str = PRINTER{PROPPRINT:device} !Key code SELF.UseVar = Str !Key code DISPLAY(SELF.Feq) END RETURN EditAction:Ignore END END If any of the above looks familiar, it should be, I stole it from one of the ABEIP methods . 3) Critical last step, add at the *module* embed level the INCLUDE('PRNPROP.CLW'),ONCE code or it won't compile. That's it. Compile and test and you'll find you can select any printer device installed on the system. This is useful if you ever need to change printer devices on the fly like you might do with point of sale systems (flip between a receipt printer and normal printer for example).
