I've downloaded a custom control (a nullable datetimepicker) and it comes packaged as a VB project. I've added the project to my solution, but I don't know where to go from there. I've never used custom controls before, so how would I go about getting this custom control in my toolbox?

you need to compile the datetimepicker project to a dll. then on your toolbar add a new item and point to the compiled dll.

It turns out that after I built the datetimepicker project, I checked the bin folder of the project and there was an exe in there. I added that to my toolbox (instead of a dll) and I was able to add the control to my form.

It looks like it works so far, so thanks for the reply!
