64位模式下StrPtr类型不匹配

Question

我在Access 2013中使用了下面的代码（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 ....

在删除Access 2013 64位运行时安装的32位组件后，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。

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
