I used this code in SDK wndProc.It executes successfully but when I execute exe of this sdk code through c# it wont write data into file.Can you please help me?

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");
