DllCall

[VicTT]

void yintomid(
    char *in,
    char *mid,
    char *out);

How do I call this function from within AutoIt?This func. is present in a dll..I can't figure out how to define a char ptr with DllStructCreate..And I'm running blind..here..pls help

[VicTT]

The function is supposed to return the result in char *out..

[VicTT]

YESSS!!!I got it to work!!!

Just in case someone is helped by this code, I'm going to post it here

$struct=DllStructCreate("char[128];char[128];char[128];")
DllStructSetData($struct,1,$in)
DllStructSetData($struct,2,$mid)
DllStructSetData($struct,3,$out)
DllCall("dlmid.dll","none","yintomid","ptr",DllStructGetPtr($struct,1),"ptr",DllStructGetPtr($struct,2),"ptr",DllStructGetPtr($struct,3))
Msgbox(0,"",DllStructGetData($struct,3))

Can't cease to amaze myself

Now that you've done it the hard way, look at DllCall()'s "str" type. You're also leaking memory doing it that way.

Yea..I need to Destroy the struct afterwards..I tried it with "str" by default, but I couldn't get a pointer to the data..

PS..Thanx for the Destroy tip..forgot to do that ..I'm pretty sloppy mostly
