Problems and questions for legacy controls

[John Olbert]

I am trying to understand how legacy controls (for example, those created
with Visual Studio C++ 6.0) work in Vs2005.

I have run into some problems.

The legacy control is MfcAxc1.ocx.

After the control is imported into Vs2005 Toolbox and then added to a
Windows Form, two files are generated--
AxInterop.MFCAXC1Lib.dll
Interop.MFCAXC1Lib.dll

The file does load fine into a Form and the App runs fine as well, the
control operates as expected.

But when I tried to get type information using GetType() (please see code
below) it returns a "null"--

string assemblyName ="AxInterop.MFCAXC1Lib, Version=1.0.0.0,
Culture=neutral, PublicKeyToken=null";
string typeName = "AxMFCAXC1Lib.AxMfcAxc1";
Type type = Type.GetType(typeName + ", " + assemblyName);
if (type != null)
{toolList.Add(type);
}

Could you tell me why two files are generated and why the Type.GetType()
returns a "null".

Any help or pointers to articles would be appreciated.

Thanks.
