CommonDialog1.FileName的值作怪,如果在保存的选择框中有选择到文件,那么文件那一栏就会不为空,而当然CommonDialog1.FileName肯定不会为空的,因为它是读那个文件名栏的。这时候只能够在CommonDialog1.CancelError = True上面一行加上错误陷阱。如下: CommonDialog1.ShowSave On Error Resume Next Err.number=0 CommonDialog1.CancelError = True if Err.number=32755 then CommonDialog1.FileName="" lpath= CommonDialog1.FileName If lpath <> "" Then SavePicture Image1.Picture, lpath Else Exit Sub End If Else lpath= "" End If这样一个应该就可以了~~~~~^_^
lpath = CommonDialog1.FileName SavePicture Image1.Picture, lpath Exit Sub err_control: If Err.Number = 32755 Then Exit Sub Else ' another error control End If
把CommonDialog1的属性CancelError设定为true. 再代码前加入: on error goto errorhandle ret = MsgBox("要保存图形吗?", vbYesNo, "") If ret = 6 then ...... ...... CommonDialog1.Filter = "图片(*.bmp)|*.bmp|所有文件(*.*)|*.*" CommonDialog1.Flags = cdlOFNPathMustExist Or cdlOFNOverwritePrompt CommonDialog1.ShowSave
lpath= CommonDialog1.FileName If lpath <> "" Then SavePicture Image1.Picture, lpath Else Exit Sub End If
Else lpath= "" End If exit sub errorhandle: exit sub
CommonDialog1.ShowSave
On Error Resume Next
Err.number=0
CommonDialog1.CancelError = True
if Err.number=32755 then CommonDialog1.FileName="" lpath= CommonDialog1.FileName
If lpath <> "" Then
SavePicture Image1.Picture, lpath
Else
Exit Sub
End If
Else
lpath= ""
End If这样一个应该就可以了~~~~~^_^
CommonDialog1.Filter = "片(*.bmp)|*.bmp|所有文件(*.*)|*.*"
CommonDialog1.Flags = cdlOFNPathMustExist Or cdlOFNOverwritePrompt
CommonDialog1.CancelError = True
CommonDialog1.ShowSave
lpath = CommonDialog1.FileName
SavePicture Image1.Picture, lpath
Exit Sub
err_control:
If Err.Number = 32755 Then
Exit Sub
Else
' another error control
End If
再代码前加入:
on error goto errorhandle
ret = MsgBox("要保存图形吗?", vbYesNo, "")
If ret = 6 then
......
......
CommonDialog1.Filter = "图片(*.bmp)|*.bmp|所有文件(*.*)|*.*"
CommonDialog1.Flags = cdlOFNPathMustExist Or cdlOFNOverwritePrompt
CommonDialog1.ShowSave
lpath= CommonDialog1.FileName
If lpath <> "" Then
SavePicture Image1.Picture, lpath
Else
Exit Sub
End If
Else
lpath= ""
End If
exit sub
errorhandle:
exit sub
