AutoItXdll and BCX

[BGM]

Hello! I am using a language called BCX, which is written like BASIC, but is converted to C for compiling. I want to use the AutoItX dll. I have the old AutoItDLL and the new AutoItX. The first function below, from AutoItDLL works fine, but the second function from AutoItX returns 0. What am I missing? I don't understand dlls and pointers as well as I should, but I am learning. If anyone can shed me some light (even though I know not many people use BCX) I would be appreciative. These functions are written in BCX code.

'this function returns the active window's title, as it should

Function GetTitle$()

dim ActWin$ as string * 16384

DECLARE FUNCTION AUTOIT_WinGetActiveTitle LIB "AutoItDLL.dll" ALIAS "AUTOIT_WinGetActiveTitle" (ActWin$)

AUTOIT_WinGetActiveTitle(ActWin$)

Function = ActWin$

End Function

'this function returns 0, using AutoItX

Function GetTitle2$()

dim raw ActWin$ as string * 1000

Declare Function AU3_WinGetTitle LIB "AutoItX3.dll" alias "AU3_WinGetTitle" (szTitle$, szText$, ActWin$, nBufSize)

AU3_WinGetTitle("", "", ActWin$, len(ActWin$)+1)

Function = ActWin$

End Function

Thanks y'all. - BGM

First of all, a problem I see is that you are declaring the AutoItX function inside another function. Those DECLARE statements should not be inside your other functions.

Thank you very much, Mr. Robertson. I moved those function declarations out of the functions as you suggested, but the AutoItX3DLL still returns the 0 for no window found. I understand that the third variable in the function call is a pointer to a string variable to hold it - that is, the function will fill that variable with the retrieved window title. Could it be a problem with trying to match the active window (which is what I want) by sending the first parameter as "" ?

It might be a problem of "". Try using "[ACTIVE]" instead.

Well, I tried that, and to no avail. Now, one thing I did see was when I try to use AU3_Send, instead of sending the string I specify, it sends this: ??????????????????????????? So I think maybe there is a problem due to unicode. I don't understand unicode problems very well, but I notice that I don't have the same problem using the AutoItDLL.dll, which doesn't use any unicode - the problem is only with the AutoIt3X.dll.

[Richard Robertson]

Ah yes. Unicode could be the problem.

I don't know anything about BCX, but try using _T("[ACTIVE]"). A page I found shows that as converting to unicode strings.

[BGM]

Well, I figured out another way to capture the active window. I can send characters to it using AUTOITDLL.dll, but not with AutoIt3X. So, I guess I will go with what works. Thanks for your help, Mr. Robertson.

AutoItDLL is ancient... What version of AutoIt is that from?

[BGM]

Oh, gosh, I don't know what version. I found it somewhere. It does work! I'd rather use the newer one, but it doesn't work. I do notice, however, in the old one, that it doesn't even have the parameter in the send method for specifying whether keys are sent raw or not raw!
