This does indeed re-enable Visual Styles! And for me this workaround is completely acceptable. JeremyKuhne Have you already loaded the assembly?
Either by Assembly. Load or running code inside that assembly? Do you at least have a valid Assembly object for the target assembly? Can you open a new issue with detailed repro steps?
Note that I am currently:. As much detail as you can put in the new issue would be great. Please try to minimize the repro as well. This will help us reproduce the error. It requires a manifest file or a native resource from a PE image. The fix I'm attempting is to use hModule instead of lpSource.
I'll try and dump the manifest file to the temp folder to see if that works, but that is something I'd rather not do if possible. I've looking into this couple of weeks ago and this will need a different solution. My understanding of the problem:. The core issue here is that in. One possible solution would be to:. What is the the prescribed way to detect that we're in single file mode? Detect single-file - for this case checking typeof Application. Empty should do - the definition is that Location is empty string if the assembly was loaded from memory which is more or less what single-file does , but would also happen for things like loading assembly from a byte[] and so on.
We intentionally don't have a specific API to detect single-file - we kind of hope that people will be able to write code which works in either case. Unfortunately native Win32 resources are The problem will be collisions - but maybe something along those lines.
Or have an item metadata which would tell SDK to do this. Just like we have one to exclude it from the bundle, we could have CopyWin32ResourcesToBundle better name obviously. I think that may be the better choice, we would need to know what the identifier would be in code and I don't know how we would do that if there was auto collision renaming. I wasn't thinking about auto-rename - that's just asking for trouble.
Either it would work, or fail. If you have a lot of owner drawing going on, SystemAware is likely to break you, if you only took 96dpi into account to begin with. So, having control over the HighDPI mode even at runtime is often essential. This approach is cleaner. Dpi handling in winforms happen in the very begining. We may be able to set it programatically in the application but if users want to change it, our dpi related values are cached and may not respond as expected.
ALso, when winforms application launched by a host process for ex: Debugging from VS , All dpi related values are cached much before we get to the starting point of winforms application.
I agree that supporting high dpi is currently very challenging to put it nicely in winforms. I did a quick search in the winforms codebase and there is a lot of code in the individual controls to deal with this issue. I think the best maybe only? This way, most applications will not have to deal with handling different scaling factor at all maybe only provide bitmap images in multiple sizes. The transformation between effective and physical pixels can then be handled by the low level rendering code.
It does not matter if the value is added now or later. I had not tested it. Another point about the enum worth noting here is that if you send Uninitalized to windows, for example, to set the thread context, windows will refuse to do this; so we will have to make sure we're checking for this kind of thing.
I would prefer to live in a world where we track such things with a boolean of some kind instead of part of the enum, but this is not the end of the world. If yes, KlausLoeffelmann could you update the initial description in the very top? Skip to content. Star 3. In case we build for x64 then processorArchitecture should be "amd64" and in case we build with "Any CPU" then it should be defined as "msil".
Important to mention here is that it is always better to build managed for specific architecture, namely x86 or x64, because our COM consumers are probably unmanaged and either x86 or x In case we build our managed COM component with "Any CPU" settings it means it will be at runtime ,depending on operating system architecture, compiled by Just-In-Time Compiler to either x86 or x64 assembly image which can break your 32 bit client running on 64 bit OS.
To sum up, it is better to have 32 and 64 bit manifest for corresponding targets. Next element in our manifest is clrClass. This is where we define types we want to expose as COM Component.
RuntimeVersion is version of. NET framework need for component to run. Only thing we are still missing on client side is also a manifest file which will tell our application where to search for those COM types.
We simple add following app. This time it is quite self explanatory. Dependent assembly simply describes our COM dll. Next and last step is to embed this manifest file into our executable. Under Additional Manifest Files we add name of our manifest file. It is very important to know how Activation context is created and how manifests come into play.
Even though we have embedded manifest into our COM client application, if we start debugging it from Visual Studio or better yet if we let Visual Studio initialize debugging by pressing F5 then our application will be loaded from inside VS hosting process and this way our embedded manifest is completely ignored and our application fails to initialize COM components.
There is option to disable this behavior. To go around this, we need to first start our application and then attach visual studio to it. Important to remember is that when creating Activation Context manifest from Caller, top process holding all other, will be used when searching for reg-free COM components. In case we have WinForms application and it uses manifest as described above to create Activation Context and as we know WinForms comes out of the package with call to Application.
EnableVisualStyles in Main method, it will break creation of "our" activation context. You only need to embed the manifest on the release version, so it only needs to be done once per app.
If you want to see how the app looks with Visual Style during Design you can apply a Manifest to devenv. This discussion thread is closed Start new discussion. Similar topics. NET Framework.
