I am working with VB6. Here, i have a form with User name and password fields. I do no want the user to be allowed to type in capital letters in these two fields. only small letters should be allowed. how can this be done???
推荐答案
在文本框的KeyDown或KeyPress事件中（我假设它们是文本框）只需检查收到的值。
如果你不喜欢你所看到的，要么阻止它通过，要么将它转换为小写。
In the KeyDown or KeyPress event for the textbox (I''m assuming they''re textboxes) just check what value was received.
If you don''t like what you see, either prevent it going through, or convert it to lowercase.
嗯？两个字段（用户名和密码）仅接受小写？这很不寻常^ ^

Huh? Accepting only lowercase for both fields (username and password)? This is unusual ^ ^
