VB6 Impersonation in Windows 7

Hi,

I have a legacy application that contains some VB6 impersonation code on startup.

I am trying to make the application function on Windows 7.  I've tried creating a SHIM and also used the Standard User Analyzer to 'mitigate' issues, with no success.

To be clear, I am right-clicking the application and selecting 'run as administrator'.  There is a chance the application is calling another application, but I'm sure if the first app is run as 'admin' then the rest would follow?

The error message:

ImpersonationVB6:
CreateProcessWithLogonW() failed with error 740

I don't require the application to process the impersonation seqment and simply want the error to go away!

Any ideas?

What about Right-click, run in XP Compatibility Mode?

Try creating a manifest file for your application.

Here's a sample that I think should work:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
    <assemblyIdentity version="1.1.0.24" processorArchitecture="X86" name="MyApplication" type="win32"/>
    <description>This is my VB6 application</description>
    <dependency>
        <dependentAssembly>
            <assemblyIdentity type="win32" name="Microsoft.Windows.Common-Controls" 
             version="6.0.0.0" processorArchitecture="X86" 
             publicKeyToken="6595b64144ccf1df" language="*"/>
        </dependentAssembly>
    </dependency>
    <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
        <security>
            <requestedPrivileges>
                 <requestedExecutionLevel  level="requireAdministrator" uiAccess="false" />
            </requestedPrivileges>
        </security>
    </trustInfo>
</assembly>

Open in new window


Copy the above into a text file, adjust the "name" and "description" tags to fit your application, call the file like your application and add a '.manifest', i.e. "myapp.exe.manifest". Copy that manifest file into the application's installation folder next to the executable. Then try launching the program again.

That didn't work, thanks anyway :)  I'm thinking I need to 'fool' the OS into thinking the VB6 impersonation code is working... any more ideas anyone?

Just came across this one application virtualizer: http://www.evalaze.de/en/Evalaze-Softwarevirtualisierung-Evalazer/

It promises to be able to run "old applications" (even 16-bit ones) under modern operating systems.
Maybe that will also apply to your problem program.

Hi torimar, thanks but virtualising the app isn't an option...

I'd still really like some help with this. It's to the point of the vendor reengineering the app, a very expensive project..

My apologies for responding with a totally non-helpful comment..
But I think you - like us - are out of luck. Microsoft is determined to close all VB6 functionality within a few years and are refusing to "fix" any aspect of VB6 that has already ceased to work.
Our company is facing the expense of re-writing millions of lines of VB6 code (maybe $100,000?)
Every other software language on the planet has had major upgrades - but always in backwards compatible steps that involved an expense of just a few percent of project value.
The approx 30% impost of converting VB6 to DotNet is worthy of a class action by the 10s of thousands of programmers affected. I saw (and joined) a link to such a class action at www vs2020.com - see article on "Microsoft Issues"

Yep, figured as much.  I guess the only plus side is the amount of work it'll generate in the industry (I'm clutching at straws here...).  Thanks the information, interesting site.
