That code is C++ code. Are you trying to convert that to C#? That code is opening a file each time a key is pressed. That seems innefficient. Since this is only a small part of the program I probably misunderstand but based on what I see the file should not be opened at that time. I do not understand execute exe of this sdk code through c#. Do you mean that you are executing the unmanaged C++ program from C# but the C++ program is not working? How are you executing the C++ program?

Hi If you write some content into the file then (include System.IO namespace) string str = Hi! How are you?; //Write the data into file. FileStream fileStream = new FileStream(@c:	ype.txt FileMode.Append FileAccess.Write); StreamWriter streamWriter = new StreamWriter(fileStream); streamWriter.Write(str); streamWriter.Close(); fileStream.Close(); If you want to open the same file after this content written into file then System.Diagnostics.Process.Start(@c:\Test.txt);
