Question

vb中报错 要求对象是怎么回事？

我想做个图片翻转的程序，单击按钮1或按钮3可以实现图像的翻转。请高手帮忙看下程序。多谢。

Answer 1

1、把(object.)去掉
2、stretchbit之后需要插入1个空格

您的方法无法解决。出现新错误：子程序或函数未定义。

追答

声明过stretchbit吗，没有在通用部分添加下面的声明：
Private Declare Function StretchBlt Lib "gdi32" Alias "StretchBlt" (ByVal hdc As Long, ByVal x As Long, ByVal y As Long, ByVal nWidth As Long, ByVal nHeight As Long, ByVal hSrcDC As Long, ByVal xSrc As Long, ByVal ySrc As Long, ByVal nSrcWidth As Long, ByVal nSrcHeight As Long, ByVal dwRop As Long) As Long
