XLL+ Class Library (7.0)

Find/Replace

Our next example of a macro function makes use of the CXllFinder class.

Note: the full code for this example can be found in the project FindReplace in the Samples sub-directory.

Create the function

Create a new function FindReplace() as shown below.

Name: FindReplace

Amend the code

Add the following line near the top of tutorial1.cpp:

CopyC++
#include <XllFinder.h>

Amend the generated code as shown below, and build the project.

CopyC++
CXlOper* FindReplace_Impl(CXlOper& xloResult)
{
    // End of generated code 
//}}XLP_SRC 
    const TCHAR* apszPairs[] = {
        _T("Fred"), _T("Freda"),
        _T("George"), _T("Georgina"),
        0
    };

    // Iterate through each find/replace task 
    for (int i = 0; apszPairs[i]; i += 2) {
        // Create a finder
        CXllFinder finder(apszPairs[i], FALSE, TRUE);

        // Alternatively - create a finder for a specific sheet 
        //CXllFinder finder(apszPairs[i], FALSE, TRUE, _T("FindReplace.xls"), _T("Sheet2")); 
 
        // Look for each match
        CXlRef xlrFind;
        while (finder.FindNext(xlrFind)) {
            // Inspect the current value
            CXlOper xloValue;
            finder.GetCurrentValue(xloValue);
            TRACE(_T("%s\n"), (LPCTSTR)xloValue.ToString());
            // Change the value in the matched cell
            finder.SetCurrentValue(apszPairs[i + 1]);
        }
    }
    return xloResult.Ret();
}

Run the macro

Build the project, and start Excel.

Type the values "George" and "Fred" into several cells.

Using the Alt-F8 key (or with one of the other methods described in the last topic), run the FindReplace macro. Note that each of the Georges and Freds turn to their feminine equivalents.
