I am using Flutter to develop a Windows program, Need to disable input method, Find the relevant documentation, you can use the ImmDisableIME(0) method to disable the input method. But when I try to call this method, An exception was reported when running the project.

main.cpp

win32_window.cpp

How to properly disable the input method?

CodePudding user response：

An exception was reported when running the project

No. An exception was not reported when running the project. Rather, your program never ran to begin with because it had a compiler error.

Because you are passing -1 to a function expecting an unsigned integer (DWORD), the compiler is warning you (C4245). And your build environment treats warnings as errors (C2220).

To invoke it with -1 such that it disables for all threads in the current process, then invoke it as follows with a cast. It's as easy as that.

DWORD dwParam = (DWORD)(-1);
ImmDisableIME(dwParam);
