使用VB读取EXCEL数据的小程序

程序界面

VB生成EXE工程时可能由于系统原因会导致按钮文字显示不全，缺字少字的情况，网上搜了好多帖子，有说DLL文件缺失，有说框体不够大等等，我全都尝试了一遍都没有解决，最后本人使用了一个比较LOW的办法：在按钮Caption属性中输入文字时多加了些空格，终于解决了

部分代码

代码片如下：.

    Set excel_Book = excel_App.Workbooks.Open(App.Path + "\MD5.xls")
    Set excel_sheet1 = excel_Book.Worksheets("sheet1")
    Set excel_sheet2 = excel_Book.Worksheets("sheet2")

End Sub
