Requirements for this Issue

The source code in this issue is designed for all versions of Visual Basic.

In this Issue

In this issue we are going to introduce a function to replace characters in a string. You can use this code to provide a simple search/replace feature in your applications.

ReplaceChars function

To use this function, just add it to any project or module you are working on and call ReplaceChars as described in the Sample Usage section.

Parameters

• sItemData - The string you want to search and replace into.
• sSrc - The character or string you want to search for.
• sDest - The character or string you want to replace sSrc with.

Return Value

The new string will be returned. The new string will have replaced all occurences of sSrc with sDest.

Sample Usage

sNewString = ReplaceChars("C:/APPS/DATA/NEW", "/", "\")

This call will replace all occurences of the word "test" with the word "Test" and return the new string in sNewString. The new string will be "This is a Test"

Source Code

To see the source code for this issue you must be a subscriber to Code of the Week. If you are a subscriber the source code is available at the following address: http://www.codeoftheweek.com/membersonly/bi/0009.html

Comments on the Source Code

There are a several enhancements that can be made to this function. This will be left as an exercise for the programmer. Some ideas we came up with were:

• Provide a case-insensitive search
• Ability to work directly with a text box or a list box
• Verification step to ask if the user really wants to replace a particular occurence or all occurences
• Search using pattern matching.

Some of these features might be implemented in future COTW issues. If you enhance this function, please let us know and we will pass it along to our members.

If you have any questions that you can not seem to figure out, drop us a email at info@codeoftheweek.com and we will do our best to help you out.
