How to access my usercontrol in other program?

The .Net Customized components is where the controls will actually show up, but you'll have to have a library DLL or Executable to for linkage. When you compile your code for the control a DLL is created in the BIN folder of the control's project file. To get your custom control into the toolbox: 1. Right click on the toolbox and select "Add/Remove controls" 2. Click the browse button. 3. Browse to the BIN folder of your control's project and select the .DLL file there. 4. All the controls located in that DLL will be added to the custom controls tab and the controls will be in your toolbox. If for some reason the control doesn't show up, it could be because you haven't used a namespace convention properly or it may not be keyed to your project.

Hi, Are you sure you create a windows control library? What language did you use to create the windows control library? Cheers.
