Winan,

Your project needs to have either a reference to the other project/DLL or the .DLL name needs to be fully qualified as to where the file is located. Your code that you've shown below, looks a bit different than the sample I posted, but I assume that your Activator object is created elsewhere and that is supposed to be the loaded .DLL, correct?

In other words, when I have Form2 in the same project, all I need is this:

string DLLName = "ClassLibrary1.dll";
string ClassName = "ClassLibrary1.Form2";

But, if it's in a different project and I don't want to add a reference to that project, then I can fully qualify the .DLL name to get the same results:

string DLLName = "C:\\DotNetApps\\TestIt\\ClassLibrary1\\bin\\Debug\\ClassLibrary1.dll";
string ClassName = "ClassLibrary1.Form2";
