GetWindow() , GetWindowText()..Can I use it inVFP ? 1

[Brezhnev]

Good day everybody!
Can I use c-functions GetWindow() and GetWindowText() in VFP? I am trying it , but return value is always 0 which is indication that something is wrong.Here is my code :
*---------------
LPARAMETERS tnHandle,tcTextString,tnMaxCount

DECLARE INTEGER GetWindowText IN user32.dll;
INTEGER lnHandle,;
STRING @lcTextString,;
INTEGER lnMaxCount

RETURN GetWindowText(tnHandle,tcTextString,tnMaxCount)
*----------------
What i am trying to do is simple : get the title of running window , but lcTextString is always empty...
Any suggestions what am I doing wrong ?

Thanks a lot

Brezhnev,

I have some sample code for you. See:

if you want to know the name of the running window(form) use
?thisform.caption
and the name will be show
or
var=thisform.caption
to store the name in some var.

Brezhnev,

lcTextString is always empty...

You need to create the variable first:

lcTextString = REPLICATE(CHR(0),254)

Do that before you call the function.

BluePanic,

I think (but am not sure) that Brezhnev wants the title of a window from another application. If he wants a VFP window caption, your suggestion is good.
