vb3：更改为区域日期格式

Question

我在vb3代码中设置了日期为31/12/2200的错误，并跳转出错，告诉格式不像本地机器。

解决方案是手动设置12/31/2200，但我感兴趣的是让机器的语言环境自动生成。

如何在vb3中更改区域日期？

我不能帮你用VB3。我现在很多年都没有见过。我可以给你一些能在VB5/VB6中工作的东西。我不知道它会转移到VB3有多好。希望如果它需要工作，你可以将它翻译成VB3或找到可以的人。你会想添加适当的错误处理。

Private Declare Function GetLocaleInfo Lib "kernel32" Alias "GetLocaleInfoA" (ByVal Locale As Long, ByVal LCType As Long, ByVal lpLCData As String, ByVal cchData As Long) As Long 
Private Const LOCALE_USER_DEFAULT = &H400 
Private Const LOCALE_SSHORTDATE = &H1F ' short date format string 
Private Const LOCALE_SLONGDATE = &H20 ' long date format string 

Private Sub Form_Load() 
    Dim strMsg As String 

    strMsg = "Short Date Format: " & FormatShortDate(DateTime.Now) 
    strMsg = strMsg & vbCrLf & "Long Date Format: " & FormatLongDate(DateTime.Now) 

    MsgBox strMsg 

End Sub 

Private Function FormatShortDate(ByVal vDate As Date) As String 
    Dim strShortDateFormat As String 
    Dim lngRet As Long 
    Dim strReturn As String 

    'Get short date format 
    strShortDateFormat = Space(255) 
    lngRet = GetLocaleInfo(LOCALE_USER_DEFAULT, LOCALE_SSHORTDATE, strShortDateFormat, Len(strShortDateFormat)) 
    strShortDateFormat = Left(strShortDateFormat, lngRet - 1) 

    strReturn = Format$(vDate, strShortDateFormat) 

    FormatShortDate = strReturn 

End Function 

Private Function FormatLongDate(ByVal vDate As Date) As String 
    Dim strLongDateFormat As String 
    Dim lngRet As Long 
    Dim strReturn As String 

    'Get long date format 
    strLongDateFormat = Space(255) 
    lngRet = GetLocaleInfo(LOCALE_USER_DEFAULT, LOCALE_SLONGDATE, strLongDateFormat, Len(strLongDateFormat)) 
    strLongDateFormat = Left(strLongDateFormat, lngRet - 1) 

    strReturn = Format$(vDate, strLongDateFormat) 

    FormatLongDate = strReturn 

End Function
