stub function ole2disp.dll16 VARBSTRFROMI2 / Quanvert SPSS 1.7.3 #529

Hello,

I'm hitting a possibly unimplemented function stub function ole2disp.dll16 VARBSTRFROMI2 and my program exits. It is a Visual Basic 4.0 app, as far as I can see called Quanvert SPSS 1.7.3

version: 1056

stub function ole2disp.dll16 VARBSTRFROMI2

I can provide a trace file, if this can somehow help to fix this function, though there might be new ones after it :) ?

I added that function. You can try the latest build. Click Environment: THIS_BUILD_IS_RECOMMENDED__VCXPROJ_BUILD=1, then click Artifact to download.

@otya128 Fantastic, great news, thanks for the fast response! It did run now, though I'll be able to verify full functionality a bit later. Some err messages are there for C:\WINNT\SYSTEM\stdole.tlb now?

I already have in the settings:

@otya128 When trying to open project now I hit stub function ole2disp.dll16 SAFEARRAYREDIM do you think you can implement also this one at some point? Thanks for your patience.

sotirovlyu commented 5 years ago

Thanks for fixing it, I have downloaded latest build and tested it. I have two more questions, since the software from time to time executes external executables from its directory are they also being executed in the context of otvdm, since the main exe is started by it?

There seems to be one int21 message with registers when filesystem calls are present (like opening a project), and opening the external exe also produced same int21 calls in the console, and an error was produced.

and MsgBox:

Executing 'C:\QVTW\wqvpack.exe demo.pkd' failed Error code 0 System was out of memory, executable file was corrupt, or relocations were invalid

Win16 programs run from other win16 programs run in the same context. Ioctl command 0x73 isn't documented and the only reference I can find to it applies only to pcmcia cards which shouldn't be relevant. We'd probably need a more detailed trace to understand why wqvpack.exe failed to run.

sotirovlyu commented 5 years ago

So, can you recommend WINEDEBUG flags that can be useful here, or what other trace?

For the int21 error, it seems it was coincidence, it appears frequently when I have a filesystem browse dialog in this Visual Basic app. Wheter it would be File/Open or "Browse" button. Also sometimes navigating through the file system hierarchy seems to not work, it doesn't populate/load the dirs, it's a bit random.

cracyc commented 5 years ago

WINEDEBUG=+relay,+int21 is a good start.
