1. Does the form use any custom or usercontrols that possibly have compilation errors ? 2. If the form has DataGridViews, has the binding source or data source changed ?
If you're trying to open the form in design mode, you will often encounter such an error if there is a fatal error while trying to render one of the form components. Trying removing the components one by one from the Designer.(vb/cs) file and then open the code file and check for errors.
