Installed all in my personal PC, to check if was a permission issue, and yet I got same problem (there I have Win 7)

This is getting odd.... Running out of ideas.

Of course. Had to set up the ODBC data source (placed it in Network unstead of User). There I tested the connection with the DB.

Rechecking the registry, I found this line:

MyApp.exe QueryValue HKLM\SOFTWARE\Microsoft\MSSQLServer\Client\ConnectTo\LocalDB\SQLExpress NOT FOUND

Data base issues perhaps?

Edited: Another thing that got my attention:

MyApp.exe OpenKey HKCC\Software\GeneXus\GXData\Config NOT FOUND

(The troublesome dll access to GxData81.dll)

Checked with Regmon (had to download it appart since it was not on the suite). Same result with the registry modules (handle, inproc, etc.) At least it let me identify whith folder is the one associated with the troublesome DLL

Now I'm more confused. Since I can see the modules in regedit, so why the monitor says is not found? Perhaps lacks of user permissions?

Used the ProcMon. I got a bunch of "NAME NOT FOUND" or "FAST IO DISALLOWED" and "FILE LOCKED WITH ONLY READERS"

Noticed some of the files are related with the registry (InprocServer32, InprocHandler, AppID, etc.) A couple within an OLE folder and even the troublesome dll name, but with a .ini extension.

OK gonna try it. About the regsvr I been using both in my win 10, and of course the xp on the VM only has 1 version.

Been checking the DLL's with the dependency walker. It says some dll's are missing but they're related with Win_CORE and such (and they sugest to not try to get them individually). It's weird.

I'll let yuou know how it goes with the ProcMon

"If it works on one PC but not another then chances are your code relies on a COM object that isn't registered on the machine where it doesn't work, just like the message says." Always though that. A registry missing or something.

"it could even be a secondary one so ClassA but call ClassB internally but ClassB isn't registered but ClassA is fine." Could be. Don't have source code of the dlls, but I know the troublesome one calls another one (gxdata81.dll). Tried to register that one but gave me error because is not a valid COM (regasm neither work)

"Does this app have an installer of some kind?" Nope.

"If the COM objects used by the app have their own prefix or naming scheme you can use the registry to compare what is installed on both machines (under HKEY_CLASSES_ROOT) to see if anything obvious is missing." Not sure about that. How can I check it without the sorce code? I dont have experience with it. And someone suggested me to check registry too, but only found several folderts with weird alphanumerics names.

The point is the client requires specific functions. Sides, vendor just provides a demo software to test the scanner. If there's no needs of programming they wouldn't send the dll

Gonna submit it, but then gonna delete this repply later or tomorrow, for confidenciality

It's a Panini Vision X.

Seems it worked! thank you!

Member 14150748 2-Apr-19 10:01am View

Nevermind. Removed it and got an address.

Let's see if works now.

Member 14150748 2-Apr-19 9:56am View

Without ref the result of the method is false (and should be true). that's why I added it.

just trying many options. I'm not really sure what I'm really doing. Just need something that works

Member 14150748 2-Apr-19 9:46am View

I know there are the differences. But didnt have problems with other methods (as you can see, added the MarshalAs with all bools, the return doesnt mater much, I can change it to int). About the char, I read the equivalent is byte. was thinking to declare it as byte but then use a Convert.To with the symbol.

My main isue is with the struct. Dont have experience with them, let alone the PInvoke (it's my dfirst time using it). I dont know what else to do, been trying for weeks already, I feel frustrated, tired, and almost giving up (and I can't since it's for job purpoises)

Member 14150748 2-Apr-19 9:27am View

Sorry, I had some typos. Fixed question.
