    Return
Else
    dr=dt.find("用户名称='" & user & "'")
    If dr IsNot Nothing Then
        If pows=dr("密码") Then

如果还有问题,就这样:

button1按钮

Dim tx1 As WinForm.ComboBox = e.Form.Controls("ComboBox1")
Dim user As String=tx1.text
vars("sss") = e.Form.Controls("ComboBox2").text
Dim dept As String=e.Form.Controls("ComboBox3").text

Dim tx2 As WinForm.TextBox = e.Form.Controls("TextBox2")
Dim pows As String=tx2.text
Dim dl As WinForm.Button = e.Form.Controls("Button1")
Dim dt As DataTable=DataTables("用户表")
Dim dr As DataRow

If user="" Then
    MessageBox.show("请输入用户名称!","提示",MessageBoxButtons.OK,MessageBoxIcon.Error)
    Return
Else
    dr=dt.find("用户名称='" & user & "'")
    If dr IsNot Nothing Then
        If pows=dr("密码") Then
            PopMessage("登陆成功","提示",PopIconEnum.Infomation,1)
            dr("登陆时间")=Date.Now
            dr("登陆账套")=sss
            dr.Save()
            usna=user
            pwsd = pows
            dpt = dept
            e.Form.close
        Else
            MessageBox.show("密码错误","提示")
        End If
    Else
        MessageBox.show("用户不存在!","提示")
    End If
End If

项目,AfterOpenProject
If OpenFileArgs.count = 0 Then
    Forms("登陆").Open()
    If usna="" Then
        syscmd.project.Exit()
        Return
    End If
    syscmd.project.open(ProjectFile,vars("sss"))
