WM_NOTIFY - Invalid variable

5 posts in this topic

I have run into an issue when using the WM_NOTIFY function for editing the text in a listview. The problem is not on my machine, but on a coworkers box. When he tries to run the AU3 file on his box, he gets an error message saying that there are undefined variables ($LVN_BEGINLABELEDIT/$LVN_BEGINLABELEDITW)...

D:\Documents and Settings\guidpaug\Desktop\New Folder (2)\Daily E-mail.au3 (1244) : ==> Variable used without being declared.:

Case $LVN_BEGINLABELEDIT, $LVN_BEGINLABELEDITW

All of the #includes are in the code, so that is not the issue. The only difference that I can see is that he is running Scite version 1.79 and I am running Scite version 1.78, but ??.

Has anyone seen this before or know what is going on with this?

Thanks,

James

Why does the version of SciTe matter?

Unless you're hiding something from us then you should be more worried about that you have the same version of AutoIt.

MsgBox(262208, "AutoIt version is:", @AutoItVersion)

jbrady21,

The constants you are missing are in ListViewConstants.au3 for v3.3.2.0. I can only imagine that in an earlier version they were in another include which is why you do not have the problem. Are you both running the same version of Autoit?

Edit: See I was beaten to it - that is what comes when i am trying to follow the Test match at the same time!

We are not both running the same versions of AutoIt (3.3.0.0 for me / 3.3.2.0 for him).

I will test out the suggestion from KaFu out (Replace $LVN_BEGINLABELEDIT with $LVN_BEGINLABELEDITA) and see where this gets me.

Thanks for the quick responses,

James
