Applications run, class libraries don't. You can create an "exe" that will load your class-library and then shows your Form1.
Is there a particular reason why your project needs to be a class-library? If not, you can simply change the project type by changing the properties of the project. (Right click on your projectname in the solution-explorer, click properties, open the tabpage "Application" and change the "Output type" to "Windows Application")
Create a new application, reference your class-library and start your form from there.
1. Start Visual Studio
2. Open your project (Ctrl-Shift-O)
3. Go to the solution-explorer (Ctrl-Alt-L)
4. Right-click with your mouse on the node called "References".
5. From the popupmenu, select "Add Reference"
6. Go to the tabpage called "Browse", and locate your "assembly.dll" file.
Now you got the reference to the assembly, and you're set up to use any Forms defined in that library in your application.
You can "use" libraries in your project, you just can't "start" them like you would start, say, Microsoft Word.

I never used barcodes in crystal reports. I have found there are several barcode generators for crystal reports, but they are not freeware. Should I build my own implementation for barcodes generation for this purpose? Maybe someone has some experience in this area. Thanks in advance!
