API-Guide and toolshed

[bit6411]

Is there a way to see the constants for a specific function in API-Guide and toolshed?

[Matthew Gates]

Load the API-ToolShed, click File, Open ATS File, find and click on a file called kpdapi.ats, every constant known should be located in there.

[bit6411]

I know. But what I want to know is which constants refer to what functions

[Megatron]

Usually, the prefix of the message will help you, e.g:

WM = General Window messages
EM = Edit window messages
BM = Button Messages
LB = ListBox messages
ES = Edit control styes
LVM = ListView messages
PBM = progress bar messages
LBS = listbox style
BX = button style
SPI = system parameters info

[JoshT]

You can usually find the constants in the VC++ headers.

[bit6411]

VC++ headers?

[Megatron]

Windows.h or windowsx.h

Look in the "include" directroy of VC++

[JoshT]

When you look up the API calls in MSDN, they'll they you what .h file to include (for C++). Or if you know the name of the constant but not the value, use can use Windows "search for files containing text" with the name on the include dir to find the right one.

[Megatron]

Usually, the API's will be found in windows.h, but there are the odd exceptions e.g: mci, SAPI, DirectX

[JoshT]

Yeah, but windows.h doesn't actually define any constants. It just includes a bunch of other .h files.

[Megatron]

It defines some constants of it's own, as well as includes other ones.

[JoshT]

Hmm, the version on my computer doesn't really have anything useful in it (for VB)...

I have put a great deal of work into providing this kind of functionality in VB5 - you can download the latest iteration from Merrion Computing Dowloads (http://www.merrioncomputing.com/Download/index.htm) called EventVB.dll.

The idea is that related constants are grouped together as an enumerated type which is exported from that dll. Thus, the windows messages are enumerated thus:
