主题：[求助]备份退出进度条不执行，求教？

Dim Count As Integer
Dim cmd As New SQLCommand
cmd.CommandText = "Select Count(BH) From {SFMX}"
Count = cmd.ExecuteScalar
Dim pb As WinForm.ProgressBar = e.Form.Controls("ProgressBar1")
For i As Integer = 1 To Count
    Count = i / 3
    If i Mod 100 = 0 Then
        pb.Value = i / Count * 100   ’改为Count后失去作用。
        Application.DoEvents
    End If
Next

Dim zip As New zipFile
Dim NewName As String
NewName = "门诊收费数据备份" & Date.Today.Year & "." & Date.Today.Month & "." & Date.Today.Day & ".Table"
Dim zFile As String = "D:\MZSF.Backup\"& NewName & ".zip"
If FileSys.FileExists(zfile) Then
    zip.Open(zFile)
Else
    zip.Create(zFile)
End If
zip.AddFile(ProjectFile, NewName)
zip.Close()
Syscmd.Project.Compact(False)
Syscmd.Project.Exit(True)
e.Form.Close()

问题1，加入Count后进度条失去作用。

问题2，如何将两段合并？第二段没有在进度中体现。

我的意思是备份完毕后，进度也完毕。
