I've been trying for well over a month now, to draw something to screen with a render target other than Hwnd, but not having any success.
Can someone help me to get this done.
I will submit my entire code. I hope it's not too confusing, but any corrections will be appreciated.
The file is too large, so you will need to create a Windows Application, and then just drop in the code.
The App_Draw function is where the drawing is to be done.
I appreciate any help with this. Thanks.

Yes. I started from scratch.
I went through the steps carefully, from start to finish, and still nothing. Just the windows background.
I'm using the Device Context Render Target, since Microsoft does not recommend using the Hwnd Render Target , with which I successfully drew things to screen.
Can you look at my code? I refined it.
I updated the file which contained a mistake.
To draw with a Direct2D device context, you can follow MSDN doc at : How to render by using a Direct2D device context
I had posted some samples, like in this thread : https://learn.microsoft.com/en-us/answers/questions/1002167/migrating-from-id2d1hwndrendertarget-direct2d-1-0
I'm following the MSDN guides.
I'll look at your example though.
If you copy/paste the sample with DrawTextLayout, it should work
(it follows all MSDN steps)
I used the exact code from Microsoft. It worked, and I did a comparison with my code.
I notice only two differences.
In their example, 1) bitmap Properties Alpha Mode is set to D2D1_ALPHA_MODE_IGNORE, whereas mine is set to D2D1_ALPHA_MODE_PREMULTIPLIED, and 2) the device context options is set to D2D1_DEVICE_CONTEXT_OPTIONS_NONE, whereas mine is set to D2D1_DEVICE_CONTEXT_OPTIONS_ENABLE_MULTITHREADED_OPTIMIZATIONS.
Maybe that is causing some thread issues, but I have to adjust the code, to be sure.
I'll let you know, once I do a check.
Even by using D2D1_ALPHA_MODE_PREMULTIPLIED and D2D1_DEVICE_CONTEXT_OPTIONS_ENABLE_MULTI_THREADED_OPTIMIZATIONS, it works for me
(D2D1_ALPHA_MODE_PREMULTIPLIED is useless if you never use Alpha (in ARGB colors) and D2D1_DEVICE_CONTEXT_OPTIONS_ENABLE_MULTI_THREADED_OPTIMIZATIONS not necessary for simple drawings)
Even by using D2D1_ALPHA_MODE_PREMULTIPLIED and D2D1_DEVICE_CONTEXT_OPTIONS_ENABLE_MULTI_THREADED_OPTIMIZATIONS, it works for me (D2D1_ALPHA_MODE_PREMULTIPLIED is useless if you never use Alpha (in ARGB colors) and D2D1_DEVICE_CONTEXT_OPTIONS_ENABLE_MULTI_THREADED_OPTIMIZATIONS not necessary for simple drawings)
Yes, they worked fine for me as well.

@JWG, any update?

If it works, mark the answer as right answer to close the thread
(all your threads are left in abandoned state; people will stop trying to help if you ignore answers...)
I'm sorry. Is there a button in the comments area to mark as the answer? Also, what's the answer?
This current answer with MSDN link....
This current answer with MSDN link....
The answer by @Castorix31 ?
The one that told me to follow the guide I was following, and which didn't help me to solve the problem, since my code was no different in any significant way to cause problems, and I had to go look for where the problem really was in my code ?
The problem was not solved with the link, but
The problem was with a little mix-up in my code, but nothing was wrong with the steps I used from the Program Guide.
I'll convert that to the answer.
Sorry about leaving the answer open. I didn't realize it made a difference since I am not allowed to accept my own answer.
Sorry I can't do anything about this one, since the problem hasn't been solved, and I got no working solution.
As for this one, the answer is a comment, so I can't do anything about that.
I can't do anything about this one either, since the answer isn't helpful, and doesn't work. Would you suggest I convert something like this to an answer?
I'm sorry. The fault was my own. only one file was being loaded. I fixed the code, and it works now. Only, the mask is slightly offset. I'll have to look into what may be wrong there.
It seems better to just delete the post, since it's an error on my part, to begin with.
I think that's about all of them.
Please let me know if I missed any. Thanks.
The problem was with a little mix-up in my code, but nothing was wrong with the steps I used from the Program Guide. I can see my drawings now.
