1.4.1 x64: twain Source and windows messages
Posted: Thu Jan 19, 2023 3:49 pm
XnView: MP 1.4.1 - 64 bit
OS: Windows 64bit
Hello. I am writing own twain Source and have a problem with windows messages transferring from Source -> xnview -> Source.
According to TWAIN-2.4-Specification, page 645, the application must pass all messages to the source (in enabled state).
With XnView MP x64 the source does not receive messages what sent to the app handle.
To reproduce:
1. install my modified sample Source to windows/twain32/
2. enable the Source
3. press PostMSG button
Actual behaviour (bug): nothing happened
Expected behaviour: messagebox will appear (screenshot from XnView MP 32bit)
