hi,

VB can not handle the parallel port by itself and u need a dll file as yourself mentioned. you just need to add a module in your project and call the API functions exists in dll and thats it. You can use the function in VB then. The parallel port is &H378. So you define the port and write the data.

hmm...i m noob in vb,so is it i need to write a module myself or can download from some website?
and what is the API function?
i go find some module sample.but still have no idea about it. is it the module is the program that link the vb with the port together so that vb can access the port?
