Hello, I've developed a forms application using Visuall C++ .NET The users will enter data into the TextBox1 Edit box amed txtInputFile and then click on the PROCESS Button. Here is my complete code. I added the code to the btnProcess. But I cannot seem to get it to compile clean and run. At the bottom I listed the errors I'm getting. Can Someone help me please? Thank You...
Here is the complete code
