launching Excel via LabWindows

[theoMartin]

Hello,

I want to launch and control Excel via labwindows, I found this example : https://decibel.ni.com/content/docs/DOC-21745#comment-29359 which is perfect for me but when I am trying compiling it, I have thoses errors  :

     Undefined symbol '_ExcelRpt_WorksheetNew@12' referenced in "excelreportdemo.c".

     Undefined symbol '_ExcelRpt_ApplicationNew@8' referenced in "excelreportdemo.c".

     Undefined symbol '_ExcelRpt_WorkbookNew@8' referenced in "excelreportdemo.c".

Did someone have a solution about this problem?

Thank You.

Hello Theo,

Looking in Library Tree, you don't have any instrument loaded. Since you have excelreport.fp in your project, the instrument "Excel Report" (which also loads "Microsoft Excel 9.0 Object Library") should be loaded when opening the project or adding the fp to the project.

Could you check if you have excelreport.fp on your computer (CVI installs it in C:\Program Files\National Instruments\<CVI DIR>\toolslib\activex\excel). If it is, it might be the case that the path in your project is not correct. Right-click on excelreport.fp in workspace three, select Replace File in Project.. and select the right file. Don't you get an error when you open the project?

You can also have a look on the example project C:\Users\Public\Documents\National Instruments\<CVI DIR>\samples\activex\excel\excelreportdemo.prj"
