How can i refer a C# dll in MFC dll

Question

Hi For one of the MFC dll application(which creates acrobat plug-in) i want to add a reference to a C# dll. I created the MFC dll application(with /clr option to refer managed C# object) it complied and executed fine before adding C# class reference once i added that C# dll and tried to get a object reference instance(using gcnew) it is not getting it but application raising an exception saying File not found error for that C# dll. Can't we add reference to C# dll in an MFC dll application? if we can how to do what's mistake i am doing? Any help would be highly appreciated. palaksha

Thank you Mike for your quick reply Yes i tried putting my C# dll in main project folder and pointing the reference to that but no use. i added your code and compiled it before that i added using namespace System; using namespace System::Windows; using namespace System::String; and in Add New reference tab i added System WindowsBase UIAutomationTypes References But after compiling am getting rror C2867: 'System::String' : is not a namespace error what's the wrong with my settings Please help me

yes you can because I just did it in my own app. Setting the /clr option should work along with adding a reference like you did. If you are getting a file not found maybe check the properties on the reference and see if it needs to be copied to the current directory. Make sure also that you can write manage code first inside your C++ app. e.g. using namespace System::String; String^ myString = gcnew(Hello World); You should be able to do this without adding the reference. Make sure this works. (I may have forgotten another line )_ -Mike
