Excel Addin open RRS feed

  • Question

  • Hello,

    I'm using MS Excel 2010. I developed an addin in VBA as an xlam file. The addin contains more than a hundred of user defined functions (UDFs). In Thisworkbook module of the addin, I wrote a Workbook_AddInstall event procedure in which I register all of my UDFs in a function category named "HidroXL" along with their descriptions and arguments.

    When I install the addin, I can see my functions categorized in my custom "HidroXL" category. It works fine. The problem is that when I cexit Excel and restart it, my custom category "HidroXL" is gone and replaced by another xll addin's name. I tried putting the UDF registration codes in Workbook_open and Auto_open subroutines. No success.

    Do Excel loads the installed addin files each time the application starts? Or do I have to write another code for that, for instance in a template workbook?

    Thank you in advance for your kind help.

    Questions that may help... 
      Are you using the Application.MacroOptions method to assign the category?
      Are the functions to be called from a worksheet using a formula  or   called by other functions/subs?

  • Thanks,

    I found a way around my problem. It's solved. 

    I put my registry codes (Application.Macrooptions method) into a Workbook_Open procedure. And wrote an Application.Workbooks.Add statement before registering the functions. The program works very fine.
