Doesn't work with a different KeePass version (2.45)

[gjf]

This plugin simply doesn't work with KeePass 2.42. Please update it.

[MircoBabin]

I tested the plugin with KeePass 2.42 and everything functions normally.

Can you describe in more detail what isn't working ?

[gjf]

[MircoBabin]

What language is this message in ? Could provide a translation please ? I can't read this language.

[MircoBabin]

I have some additional questions:

1) What Windows version are you using ? (Windows/7, Windows/10, ...) 2) What .NET frameworks are installed ? (https://docs.microsoft.com/en-us/dotnet/framework/migration-guide/how-to-determine-which-versions-are-installed)

[gjf]

1. Win10 Pro x64 (1809)
2. 4.7.03190

I got the same error, with the debugger I get:

I have been able to temporarily correct the problem by re-adding the reference to keepass and rebuilding, but changing version of keepass still cause the problem.

@ejohnsonbegin, thank you for the detailed report.

It looks like some kind of .NET dll-hell problem. I looked at KeePassHttp plugin and they are targetting .NET v4.

I have recompiled the plugin targetting.NET v4. Could you try this ? TestUsingDotNet4.zip

[ejohnsonbegin]

I think you will need to set Specific Version to false in the reference property and use the oldest supported keepass.exe as the reference hint. By referencing my installed 2.42, I was able to use it with the portable 2.43 the installed 2.42. If I was building by referencing 2.43, it wasn't working with 2.42. None were working with my custom build 2.43 because the PublicKeyToken wasn't matching.

2.44 update - same issue.

[MircoBabin]

I have published Version 2.1 trying to address the problem with a different KeePass Version.

Version 2.1 is compiled against KeePass 2.44, so will work with KeePass 2.44. The question is: will it also work out of the box when KeePass 2.45 is released ?

[gjf]

MicroBabin, the answer is NO.

[MircoBabin]

@gjf

• What errormessage is displayed ?
• Do you use the official KeePass distribution or do you compile KeePass yourself ?
• Do you use the MSI or the portable version from keepass.info ?

[gjf]

It is official portable version running on Windows 10 Pro x64.

[MircoBabin]

Could you translate the following in English please ?

[MircoBabin]

@gjf

• Is KeePassCommander.dll located in the KeePass or the KeePass\Plugins folder ?
• Have you localized KeePass and if so how did you do that, what settings in KeePass and in what language ?

[MircoBabin]

@gjf Can you install https://github.com/awaescher/Fusion ?

• Run the program Fusion++
• Start recording
• Start KeePass
• Stop recording

There should be a failure visible. When you doubleclick the failure line a detailled log will be shown. Can you post this detailled log ?

[gjf]

1. KeePass\Plugins\KeePassCommander
2. Russian.lngx is placed into KeePass\Languages keepass.config.xml contains:

   <Application>
       <LanguageFile>Russian.lngx</LanguageFile>

It was set in GUI but stored in xml like all settings.

[gjf]

Pardon, I have no time to investigate it any further with every new update. Possibly someone else can do. Sorry about that.

[MircoBabin]

If anybody stumbles upon this problem, please run KeePass in debug mode and post the logfiles.

KeePass.exe --debug --KeePassCommanderDebug=c:\temp\KeePassCommander.log

Hi, I did some digging and I think the only real issue is that the example project references the plugin files dynamically. At least it works for me fine using a newer version of KeePass after doing some small adjustments.

With the committed code everything works because there is also a KeePass version copied into the build output folder. So everything is in one place, assembly resolution is simple.

But when changing the location of the KeePassCommandDll.dll to a version installed at the regular KeePass .Net will dynamically load the KeePassCommandDll.dll just fine, BUT there is no override of the assembly resolution paths.

So by default the KeePass version copied to the build output folder is found and not the one located besides the dynamically loaded KeePassCommandDll.dll. This is prone to create issues.

To fix this either the assembly resolution event needs to be overridden or (much simpler) the dynamic loading of KeePassCommandDll.dll can be replaced by a simple project reference.

Then the complete example reduces to a one-liner: KeePassCommandDll.Api.getfirst(title);

Maybe this helps.

[MircoBabin]

@ryivus that's also a solution. But often the place of KeePassCommandDll.dll is not in the same directory as your executable. That's why it's dynamically loaded, to prevent startup errors because a referenced dll was not found.

This issue was about KeePass not starting, reporting errors because of the KeePassCommander.dll conflicting in some way with the KeePass and .NET framework versions.

Because this issue has been stale for a year now. I'm going to close it.
