The source code in this issue is designed for all versions of Visual Basic.
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.
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.
The new string will be returned. The new string will have replaced all occurences of sSrc with sDest.
sNewString = ReplaceChars("C:/APPS/DATA/NEW", "/", "\")
This call will replace all the / characters with the \ character and return the new string in sNewString. The new string will be "C:\APPS\DATA\NEW"
sNewString = ReplaceChars("C:/APPS/DATA/NEW", "/", "\\")
This call will replace all the / characters with the \\ string and return the new string in sNewString. The new string will be "C:\\APPS\\DATA\\NEW"
sNewString = ReplaceChars("This is a test", "test", "Test")
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"

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:
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.
