API functions for FoxPro 5

[ShyFox]

Hy
I found out that VFP 7.0 can use a API functions. Who can tell me where can I find a program that could give me the Fox syntax to call API functions (there's a program that I encountered for Visual Basic, I forgot it's name). I know about

http://www.news2news.com

but I do not have the net full time at work.
Thank you.
Regards.

I found out that VFP 7.0 can use a API functions.

API calls in VFP go back to at least FoxPro 2.6 as far as I can remember.

As far as I know there is no such program, you either know both VB and VFP and you understand how to translate between the two, or some one else does. Mike Gagnon

ShyFox,

Lok at DECLARE in the Help.

You use that to declare an API function within VFP. Once you have done that, you can just call the function, just like a native VFP function.

Shyfox,

If you look at the solutions example that came with VFP, you will find some examples. For example, if you want to read/write an ini file, you can use:

declare integer GetPrivateProfileString in Win32API ; string cSection, string cKey, string cDefault,; string @cBuffer, ;
integer nBufferSize, string cINIFile

and

declare integer WritePrivateProfileString in Win32API ;
string cSection, string cKey, string cValue,; string cINIFile

Then use use this in your code as you would any function.

The only trick is learning what data types to use when defining them since often, the data type information you get uses the C variable types.

Take care,

Fletcher

There is a fully documented comprehensive list of WIN32API functions at

http://www.news2news.com/vfp/?group=-1&=0,

if that helps. Mike Krausnick

Also check out the UT's (

API section.

I've had a copy of Dan Appleman's "Visual Basic Programmer's Guide to the Win32 API" around for a long time. It covers many of the "important" API calls and has lots of sample code. It's not that tough to convert most of them to VFP.

"API calls in VFP go back to at least FoxPro 2.6 as far as I can remember."

I use FoxPro for 2 years, my language is C++, so I didn't know to much of it. But thank you for telling me that. It's a think that it's good to know.
Thak you all for your help !
Regards.

For a comprehensive list of API functions, see the MSDN Library program. The syntax isn't VFP, but it is complete, and learning to translate to VFP is very useful knowledge.

Just a note:
"API calls in VFP go back to at least FoxPro 2.6 as far as I can remember."

I am using them with Fox Win 2.5......

Then obviously my memory does not go that far back. ;-)
