I'd say MerrionComputing is the man to talk to

Use the API viewer from AllAPI Guide's http://www.allapi.net.

**Leather** · Nov 7th, 2002, 04:05 AM

What do you mean by back convert?

Their is a list of constants they can be compared to...

**Wokawidget** · Nov 7th, 2002, 04:05 AM

Eg: Ok, for a treeview, I want to know what the Msg 4110 is???
ALLAPI does not back convert, you find theconstant then it gives you the value, not the other way round...

[Edit] Took out the constant declarations

Um, just find the hex value for the message passed, and go looksie

**Wokawidget** · Nov 7th, 2002, 04:10 AM

Nope, it's none of them

One of the many I am looking for is 8270 = &H204E...?

Has that solved your problem wokawidget?

**Wokawidget** · Nov 7th, 2002, 04:18 AM

errrrr....no

Ok, you need to convert the value in question into hex...

The easiest way to do this is open the windows calculator, type in the decimal value, open the scientific section and click the hex button..

Take this value and find it in the list of constants that axion supplied...

if you can't tell me and ill try to find it for you.

Basically what I am trying to do is to subclass a treeview, trap when a label edit is started, get the handle to the label edit textbox, find out it's dimensions and replace it with another control...

Woka

**Wokawidget** · Nov 7th, 2002, 04:23 AM

Try doing a google search on &H204E...

Woka

**Leather** · Nov 7th, 2002, 04:24 AM

But the listview has a before label edit event, why dont you just use this..

**Wokawidget** · Nov 7th, 2002, 04:30 AM

I am trying to keep this thread simple as not to confuse anyone, maybe I shouldn't

Trust me, I need to subclass it...I also want to do other things as well...with small animals...Oooops, wrong web site...

Just wondering

Could U not code a quick parser on the Win32API.txt and spit out the corresponding "WM_****" for a given Hex or Long value ?

**Wokawidget** · Nov 7th, 2002, 04:38 AM

Now u're talking

Why didn't I think of that...*YAWN*

Cheers...Will have a go, will let you know how I get on...
Gonna write an app which allows you to work backwards using the API txt file

Cheers,

Christ! I am very slow.........

**Wokawidget** · Nov 7th, 2002, 04:41 AM

Now know why I didn't do it like that

VB's API view is crap and doesn't have much in it, and AllAPI's viewer is saved in it's own format

Woka

**KayJay** · Nov 7th, 2002, 04:43 AM

Ok.......

Do U know how a Type Library is formatted?

**Wokawidget** · Nov 7th, 2002, 04:44 AM

G'buh?

**KayJay** · Nov 7th, 2002, 04:47 AM

U know win32.tlb? It has everything neatly "enum"ed. All functions, subs, constants, etc...

**MerrionComputin** · Nov 7th, 2002, 04:47 AM

Note that messages above WM_USER are application defined messages...so won't have an associated WM_ constant.

Currently WM_USER = &H400

**MerrionComputin** · Nov 7th, 2002, 08:45 AM

Quick and dirty utility attached....
