AutoItX3_x64.dll in java

[mremillard]

Hello.

I searched for previous information on my problem and found nothing so here goes...

I am running junits in eclipse (Indigo Service Release 2) under Windows 7.

When I make use of a 32 bit JVM and the DLL "AutoItX3.dll" all works fine. But when I try to run the same test with "AutoItX3_x64.dll" and a 64 bit JVM nothing seems to work.

In the 64 bit environment calling, say, AU3_WinGetHandle() will cause my JVM to crash. Method AU3_WinExists() never finds any windows. These both work fine when calling them with a 32 bit JVM and the 32 bit DLL.

The instance of the DLL is accessed via:

AutoItX INSTANCE = (AutoItX) Native.loadLibrary(Context.getAutoItxPath(), AutoItX.class);

What should I be changing?

Thanks.

Michael.

Sorry, my code guesser doesn't work for Java. You'll have to post your failing code. Maybe you are using wrong datatypes.

Well, let's see...

I have:

public interface AutoItX extends com.sun.jna.Library, Serializable

{

AutoItX INSTANCE = (AutoItX) Native.loadLibrary("[The path to the DLL. Either the AutoItX3.dll or AutoItX3_x64.dll]", AutoItX.class);

public int AU3_WinExists(String szTitle, String szText);

public void AU3_WinGetHandle(String szTitle, String szText, byte[] szRetText, int nBufSize);

etc...

}

Then in a junit I'll have:

static AutoItX lib = AutoItX.INSTANCE;

etc...

lib.AU3_WinGetHandle("", "", buf, buf.length);

etc...

if (lib.AU3_WinExists(pTitle, "") == 1)

{

...

}

else

{

...

}

and so on. This very same code works when in a 32bit JVM using the AutoItX.dll but fails when in a 64bit JVM using the AutoItX_x64.dll.

Note: Loading the AutoItX.dll in a 64bit JVM doesn't work.

Could you rephrase the last two sentences so that it's clear what works and what doesn't.

When I make use of a 32 bit JVM and the DLL "AutoItX3.dll" all works fine. But when I try to run the same tests with "AutoItX3_x64.dll" and a 64 bit JVM nothing seems to work.

In the 64 bit environment calling AU3_WinGetHandle() will cause my JVM to crash.

In the 64 bit environment calling AU3_WinExists() will never find any windows.

These two methods work fine when called with a 32 bit JVM and the 32 bit DLL.

That can't be that much clearer...
