vb.net 导出为excel及邮件群发

在一个服装销售软件中,要将每天的销售额通过发邮件的形式提交到老板那里.

于是:1,提取每天销售及退货情况.

2,自动导出为excel文件

3.以导出的excel为附件进行邮件群发

关键代码如下:

导出为excel文件

    Public Sub exportExcel(ByVal dgv As DataGridView)
        Try
            If dgv.RowCount = 0 Then
                MessageBox.Show("列表中无数据，导出数据失败","提示")

发送邮件代码:

操作ini文件:

Private Declare Function GetPrivateProfileString Lib "kernel32" Alias "GetPrivateProfileStringA" (ByVal lpApplicationName As String,ByVal lpKeyName As String,ByVal lpDefault As String,ByVal lpReturnedString As String,ByVal nSize As Int32,ByVal lpFileName As String) As Int32
  '写ini API函数 
  Private Declare Function WritePrivateProfileString Lib "kernel32" Alias "WritePrivateProfileStringA" (ByVal lpApplicationName As String,ByVal lpString As String,ByVal lpFileName As String) As Int32
  '读取ini文件内容 
  Public Function GetINI(ByVal Section As String,ByVal AppName As String,ByVal FileName As String) As String
    Dim Str As String = LSet(Str,256)
    GetPrivateProfileString(Section,AppName,lpDefault,Str,Len(Str),FileName)
    Return Microsoft.VisualBasic.Left(Str,InStr(Str,Chr(0)) - 1)


  End Function


  '写ini文件操作 


  Public Function WriteINI(ByVal Section As String,ByVal FileName As String) As Long
    WriteINI = WritePrivateProfileString(Section,FileName)
  End Function
