64 位模式下的 StrPtr 类型不匹配

Question

我在 Access 2013 中使用了以下代码（从网站获取）。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 ....

为 Access 2013 64 位运行时安装删除 32 位组件后，出现编译器错误。我在Declare之后添加PtrSafe，编译器就OK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，它会出现运行时错误 - StrPtr 中的类型不匹配。不知道怎么解决。

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
