How to Implement CTRL+G Functionality to "Find Again"

• Microsoft Visual FoxPro for Windows, version 3.0

SUMMARY

This article shows by example how to find another occurrence of a string in a file (Find Again) when the CTRL+G key combination is pressed.

MORE INFORMATION

In FoxPro version 2.x, the Find dialog is activated by pressing CTRL+F. To find another occurrence of a string in a text file, you can press CTRL+G key, and a new search is performed.

Visual FoxPro uses a Find dialog common to Windows-based applications on a specific platform. With this dialog, pressing CTRL+G no longer performs a "Find Again" operation. You can, however, program this functionality by explicitly calling the Find window when CTRL+G is pressed.

Step-by-Step Example

The following example code illustrates this method. To execute the sample code, follow these steps:

1. Copy and paste the code into a program (.PRG) file named FINDAGN.

2. Run the program by typing DO FINDAGN in the Command window.

3. Open a text file, and press CTRL+F. The Find dialog is activated. Type a string that reoccurs in the text file.

4. Press CTRL+G to find the string again.
