How do you make UDF's?


Recommended Posts

I'm new to scripting and Autoit, but i've already found some things that I would like to create. Where do you start when creating a UDF?

For instance, if I wanted to make a UDF for Excel(I know one exists) Where would I start? What would I need to start researching?

Any input would be appreciated

Do you want to make an UDF just for yourself or should it be useful for the community as well?

i doubt that's a beneficial segregation. if you train yourself to write a fully-qualified UDF, following all formal standards, then it will also be very much easier for yourself to use, develop and troubleshoot, even if you never share it. also it is much easier for the community to help you with your UDF when written by the standards.

@orbs ,

I think water's comment is the result of his curiosity. Because, he is the master mind behind current excel udf. So he want to know what is lacking in the current excel udf.

@kcvinu

indeed, but the OP does not know that, and water's hint may well lead him astray.

@orbs , Yeah, that's true. 

@TheDcoder , What ?  Does that word means like that ?. Oh my poor English. I just meant that, that udf is water's brain child.

Not just curiosity.
If I would have to write an UDF just for myself I'm sure I would try to adhere to the standards when writing (naming of variables etc.). But I'm sure I wouldn't invest as much time into writing the help file and examples. As I have written the UDF I'm very familiar with the subject and do not need as much explanation and examples as a newbie.
That's why I asked.

No, my question was of general nature. Not related to my Excel/ExcelChart/Word/Outlook/PowerPoint UDF ;)
But I'm always open for suggestions on how to improve the "official" UDFs.
