Question

I am unable to read the text file in windows form . i am getting the following error

 

An unhandled exception of type 'System.NotSupportedException' occurred in mscorlib.dll

I had written like this:

 

String^ strfilename = openFileDialog1->InitialDirectory + openFileDialog1 + filename;

String^ readfile = File::ReadAllText(strfilename);

 

can anyone tell me what I could do

make the IFrame runat="server" and you will be able to access it in the codebehind
