Windows Form Application

Create a form application using Visual C++ Step 0: //Create a Windows Forms application in Visual Studio 2012 –Create an empty Form1 following “how-to-VS2012” from BBL –do not add stuffs to the empty Form1 –change Form1’s Text to “CS351”: with the “Form1.h[Design]” active, open the “Properties” window, change the existing “Form1” to “CS351” –Add (copy-paste) code from main.cpp to Form1.cpp by first clicking the Form1.cpp from the “Solution Explorer” window to open it; then modifying the namespace to be your project name; –Build and run, make sure it works

Cont’d I There are two approaches to try to work out the rest of the sample code, –Approach 1 is a direct copy-paste, –Approach 2 takes each step in class. Step1, Approach 1: –Copy the sample code to the Form1.h (double click Form1 in the [Design], modify the namespace to your project name. –Or, copy the sample code file Form1.h to the project directory (replace the existing file); modify the namespace to your project name. –Build and run

Step1, Approach 2: // read the sample code to help –Open Form1.h, by double clicking Form1 in the [Design] view –Build each specific items according to the sample code. Examples: –Add label (s), change text, sizes, variable names, etc.; check code many… –Build and run Cont’d I
