Hi Wolfgang,

Restarting VS does not change anything and the ToolsVersion is 4.0 in my project also.

However, it works anyway. Thanks for your help.

Kind regards

Thomas

Hi Thomas,

your problem is rather interesting since without the SubsystemVersion element being present in the project file the message boxes are not shown appropriately. I've tested that right now by commenting out the SubsystemVersion element and then the buttons touch the lower border of the message box. This means, that VS2012 seems to be confused about this element but when running it this works correctly. Have you tried to close and reopen VS which helps often when it shows weird warnings or behaviors on my machine?

I don't know what the ToolsVersion attribute in the root element Project is used for but this could maybe be also different? In my project ToolsVersion is 4.0

Regards Wolfgang

Hello Wolfgang,

I have attached an image showing the message in VS2012.

Anyway, it works fine now. I missed to disable host process when debugging as mentioned in an earlier post.

Many thanks,

Thomas

Hi Thomas,

I tried it now with a Playground project of mine, it works fine as a .NET 4.5 project and I'm using VS2012 update 3 as well which doesn't complain about invalid child element SubsystemVersion within element PropertyGroup. I've attached my Playground.csproj-file to this post, you can find the SubsystemVersion element on line 48. With that message boxes using UltraMessageBoxManager are shown correctly.

If needed I could also provide you with the entire project so that you can try to load that on your PC.

Regards, Wolfgang

Hello Hristo,

According to you video I tried to edit the project file with no luck.

VS2012 is telling me that I am using an invalid child element "SubsystemVersion" within the element "PropertyGroup"

I am using VS2012 Update 3 with TargetFramework 4.5

Any ideas?
