I put the old solution the copy on the new computer
New VS2019
Then compile no problem, but found no the textbox drop-down box!!!!!

Then my new test program, simple interface is a textbox
Found is also unable to pop-up autocomplete drop-down box

What is
When autocompletesource is digital type of string, can pop-up drop-down box
Chinese characters is not??

AutoCompleteStringCollection. AddRange (new string [] {" 1 ", "2", "3", "4", "5", "6", "7", "eight", "11", "12", "23", "35"});//can pop-up drop-down box
AutoCompleteStringCollection. AddRange (new string [] {" king ", "the king of me", "liu", "liu", "I", "zhang qiu", "three li", "li", "" picture 1", "2"});//can't pop up

AutoCompleteStringCollection. AddRange
The add is for selected list
As for can match, see and you enter prefix are consistent
In other words, even if you have king list, unless you input is wang mou one, if you input is 123, you can't see the drop-down

In a nutshell found problems
Is the Microsoft pinyin input method problem WIN10
When the input method is the default state in English, I copy in a Chinese character in the textbox, is normal down
While it is Microsoft pinyin input method, not

I input to the input method, Chinese can pop-up drop-down box

True when it is without rhyme or reason

Remember, is the traditional Chinese input?
