GUI ScreenIO for Windows


Icons are a special type of bitmap which may be linked into your executable.  Icons are always 16x16 or 32x32 bits in size, so they're quite small.

Windows examines your executable module to see if it contains icons when it lists the module in Explorer, or when you create a shortcut to the module.  If an icon is found in the module, Windows will associate that icon with the shortcut to your application.

Creating an icon

We use a Microsoft product called ImagEdit to create the icons used in GUI ScreenIO.  ImagEdit is distributed with Microsoft software development products.

You can also obtain third-party icon editors from a variety of sources; do an Internet search on "icon editor" and you'll find plenty to choose from.

You can also find thousands of icon files on the Internet if you prefer not to create your own.

Icon files have a ".ico" extension.

Displaying an icon in your title bar

If the name of your icon in your resource script matches the name of your executable, GUI ScreenIO will automatically display it at the left side of the title bar when you run your application.

For example, if your executable is named myprog.exe, and your resource definition file contains this statement, the icon myprog.ico will be displayed in your application's title bar.

myprog     ICON    myprog.ICO
