In VB, you can use built-in functions to determine the size of letters. Here are two common methods:<\/p>\n

    \n
  1. The Asc function can convert characters into their corresponding ASCII codes. In ASCII, the range for uppercase letters is 65-90 and for lowercase letters it is 97-122, allowing for comparison of ASCII codes to determine letter size. Sample code is provided below.<\/li>\n<\/ol>\n
    Dim<\/span> letter As<\/span> String<\/span>\r\nletter = \"A\"<\/span>\r\n\r\nIf<\/span> Asc(letter) >= 65<\/span> And<\/span> Asc(letter) <= 90<\/span> Then<\/span>\r\n    ' \u5927\u5199\u5b57\u6bcd<\/span>\r\nElseIf<\/span> Asc(letter) >= 97<\/span> And<\/span> Asc(letter) <= 122<\/span> Then<\/span>\r\n    ' \u5c0f\u5199\u5b57\u6bcd<\/span>\r\nEnd<\/span> If<\/span>\r\n<\/code><\/pre>\n
      \n
    1. VB also provides the IsUpper and IsLower functions for determining if a character is an uppercase or lowercase letter. The example code is shown below:<\/li>\n<\/ol>\n
      Dim<\/span> letter As<\/span> String<\/span>\r\nletter = \"A\"<\/span>\r\n\r\nIf<\/span> Char<\/span>.IsUpper(letter) Then<\/span>\r\n    ' \u5927\u5199\u5b57\u6bcd<\/span>\r\nElseIf<\/span> Char<\/span>.IsLower(letter) Then<\/span>\r\n    ' \u5c0f\u5199\u5b57\u6bcd<\/span>\r\nEnd<\/span> If<\/span>\r\n<\/code><\/pre>\n
      It is important to note that the second method requires importing the System namespace, which means adding the Imports System statement at the beginning of the code.<\/p>\n","protected":false},"excerpt":{"rendered":"
