VB的问题。。真的很急。。。

Private Sub Command2_Click()
   Me.Picture = Me.Image
   '保存捕捉的图片

   SavePicture Image, "D:\1.gif"
End Sub
怎么做才不会替换文件，我要每一次按按钮就保存一张图..

自动生成保存的文件名不就可以了么

我是VC迷 发表于 2010-7-16 19:58

Private Sub Command2_Click()
dim ab as integer
Me.Picture = Me.Image
ab=ab+1
SavePicture Image, (ab+".gif")
End Sub

希望可以帮助到你

第5行应该是 SavePicture Image, (ab & ".gif") 不好意思发错了

3L的代码始终把图片保存在当前目录下的1.gif
可以通过dir（）来判断文件是否存在，如果存在，则重新生成文件名，再判断是否存在；直到新文件名不存在为止。
strNewName="新文件名"
while dir$(strNewName) <> ""
strNewName="重新生成文件名"
wend

'savePicture ....

代码过少,使用随机的文件名比较好。

SavePicture Image, "D:\1.bmp" '可以的话，请改成![em16]

路过，个人认为让保存的文件名产生一下变化就不会出现被替换的问题了
