I define my class and inherit from Microsoft.PointOfService.BillDispenser.

I'm trying to implement printing functionality into a simple program for my company. It's not necessary, but it would be a nice finishing touch for everyone. And really, in practice, my printing feature works. My problem is that each line is printed on a separate page of paper and I can't find a way to just like, print a page.
It doesn't have to be fancy. I know that I won't need word wrap, nor will anyone ever print more than one page. Here's my ginked & modified code thus far:
Private Sub PrintDocument1_PrintPage(ByVal sender As System.Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage

View 1 RepliesI have written a set of functions in VB 9 that I want to be able to call from several different programs (also VB 9). I compiled the functions into a dll and I am attempting to call the functions but to no avail. Within the dll project, the class is Public as are the Functions.Within the exe project, I have declared the dll functions using Declare statements of the following form:Public Declare Auto Function FunctionName Lib "DllName.dll" ( ) As String.I thought that this was all that is required. It builds fine but when I attempt to call the dll functions, no entry point is found.
View 3 RepliesI am the author of the MAPM arbitrary precision math library. This is a library which allows the user to make any calculation to any desired precision level. The library is written in straight ANSI C.
On many occasions, I get an email on how to use the library from a VB.NET / Visual Basic application. I have very little basic experience, and I don't know what to tell them. I would really like to tell them how to proceed to call MAPM from a basic application.
Let's assume they can compile the library with a C compiler and create a DLL.
