imgui demo (d3d9) crashes when pressing keyboard button

[ghost]

Hello together,

I copy paste the dx9 example and everything works/looks fine. Except when I press any keyboard button, then I get an error:

Debug Console output:
Assertion failed: ImGui::IsNamedKey(key), file (path)\vcpkg\buildtrees\imgui\src\v1.88-34c93572a3.clean\imgui.cpp, line 1280

Can somebody help me pls?

My imgui version 1.88

Hello,
I cannot seem to repro the issue here.

• Could you open Demo->Tools->About and copy and paste the blurb here?
• What is the value of key in the debugger?
• How are you building "Dear ImGui DirectX9 Example" if your copy of imgui comes from vcpkg? I don't assume vcpkg include the examples. If you are building "Dear ImGui DirectX9 Example" from our repo presumably it should use the version in our repo and not from vcpkg?

Hello ocornut,

thanks for your fast reply.
Your third point reminded me that with the installation with vcpkg I only had the imgui.h and manually downloaded the imgui_impl_dx9 and imgui_impl.win32 and added them to my project. This was not the best idea, since apparently the two manually downloaded parts caused the problem.

For the solution I removed the old imgui_impl_dx9/imgui_impl.win32 files and replaced them with the fresh downloaded realese 1.88. Now the error is fixed.

I'm not using vcpkg for so long, is there a reason why I don't install the backend data with the imgui installation with vcpkg?

If you still want to see the about blurb:
