StrPtr类型在64位模式下不匹配

Question

我在Access 2013中使用了以下代码（从网站上获取了它）。它没有任何问题。

Private Declare Function GdipCreateBitmapFromFile Lib "gdiplus.dll" (ByVal FileName As Long, bitmap As Long) As Long

If GdipCreateBitmapFromFile(StrPtr(sFileName), hPic) = 0 Then ....

在为Access 2013 64位运行时安装删除32位组件之后，出现编译器错误。我在声明后添加PtrSafe，编译器就可以了。

Private Declare PtrSafe Function GdipCreateBitmapFromFile Lib "gdiplus.dll" (ByVal FileName As Long, bitmap As Long) As Long

If GdipCreateBitmapFromFile(StrPtr(sFileName), hPic) = 0 Then ....

但是，它将出现运行时错误-StrPtr中的类型不匹配。不知道如何解决。

Answer 1

将LongPtr用于64位而不是Long。

Private Declare PtrSafe Function GdipCreateBitmapFromFile Lib "gdiplus.dll" (ByVal FileName As LongPtr, bitmap As Long) As Long

Answer 2

我将如何解决这个问题？

公共函数ToUTF8（ByRef inString作为字符串）作为字符串昏暗的BufLen只要

BufLen = WideCharToMultiByte(CP_UTF8, 0&, ByVal StrPtr(inString), _
    Len(inString), vbNullString, 0&, vbNullString, ByVal 0&)
If (BufLen > 0) Then
    ToUTF8 = Space$(BufLen)
    Call WideCharToMultiByte(CP_UTF8, 0&, ByVal StrPtr(inString), _
        Len(inString), ToUTF8, BufLen, vbNullString, ByVal 0&)
End If
