Cross Word Application in C#.Net

Purpose of this Application: “A crossword is a word puzzle that normally takes the form of a square or a rectangular grid of white and shaded squares.” Wikipedia I am very much interested in the Cross Words Games [CWG]. So I developed this Application. 

private static bool chkEmpty;
private static bool  IdetifyContNull(System.Windows.Forms.TextBox txt)
{
    if (txt.Text == "")
    {
        chkEmpty = true;
    }
    else
    {
        chkEmpty = false;
    }
    return chkEmpty;
} 

Application Processing:

                   Two Command buttons in the Application. They are Question Button and Answer Button.

 Question Button:

• Clicks “Question” Button.
• Question will display in the RichTextBox.

Answer Button:

• ·         Check Answer.
• ·         Display Message Box.

Now we will go to Coding Section.

 Step by Step Processing

Create a Project in the VS C#.2008.

From name: frmCrossword.cs.

Controls in Application:

    Label, Textboxes, Panel and Buttons.
