cexcel源码
Ⅰ 别人用excel表格做的管理系统怎么查看此管理系统的源码
新建excel文件，alt+F11进入VBA编辑器，插入模块，输入以下代码：
Sub MoveProtect()
Dim FileName As String
FileName = Application.GetOpenFilename("Excel文件（*.xls & *.xla）,*.xls;*.xla", , "VBA破解")
If FileName = CStr(False) Then
Exit Sub
Else
VBAPassword FileName, False ' 引用下面的自定义函数
End If
End Sub
Private Function VBAPassword(FileName As String, Optional Protect As Boolean = False)
If Dir(FileName) = "" Then
Exit Function
Else
FileCopy FileName, FileName & ".bak"
End If
Dim GetData As String * 5
Open FileName For Binary As #1
Dim CMGs As Long
Dim DPBo As Long
For i = 1 To LOF(1)
Get #1, i, GetData
If GetData = "CMG=""" Then CMGs = i
If GetData = "[Host" Then DPBo = i - 2: Exit For
Next
If CMGs = 0 Then
MsgBox "请先对VBA编码设置一个保护密码...", 32, "提示"
Exit Function
End If
If Protect = False Then
Dim St As String * 2
Dim s20 As String * 1 '取得一个0D0A十六进制字串
Get #1, CMGs - 2, St '取得一个20十六制字串
Get #1, DPBo + 16, s20 '替换加密部份机码
For i = CMGs To DPBo Step 2
Put #1, i, St
Next '加入不配对符号
If (DPBo - CMGs) Mod 2 <> 0 Then
Put #1, DPBo + 1, s20
End If
MsgBox "文件解密成功......", 32, "提示"
Else
Dim MMs As String * 5
MMs = "DPB="""
Put #1, CMGs, MMs
MsgBox "对文件特殊加密成功......", 32, "提示"
End If
Close #1
End Function
2. 运行上面的代码，选择你的文件，移除密码成功后打开文件，按alt+F11查看源码：
Ⅱ excel函数公式=源码!$F4是什么意思
sheet!a1 这个是引用其它工作表单元格的一般格式，sheet是工作表的名字，就是你问题中的"源码",F4就是名为"源码"的工作表里的F4单元格,=源码!$F4的意思就是公式所在单元格等于源码工作表的F4单元格的内容
Ⅲ 求一个C# Excel导入数据库的源码
环境：c#.2005+Access+ Sql
一、把DataTable插入数据库
public static void DataTableToDB()
{
string _strExcelFileName = @"D:\example.xls";
DataTable dtExcel = ExcelToDataTable(_strExcelFileName,"Sheet1");
for (int i = 0; i < dtExcel.Rows.Count; i++)
{
InsertDataToAccess(dtExcel.Rows[i][0].ToString(), float.Parse(dtExcel.Rows[i][1].ToString()));
}
}
二、把Excel数据读入DataTable
public static DataTable ExcelToDataTable(string strExcelFileName, string strSheetName)
{
string strConn = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + strExcelFileName + ";" +"Extended Properties=Excel 5.0;";
string strExcel = string.Format("select * from [{0}$]", strSheetName);
DataSet ds = new DataSet();
using (OleDbConnection conn = new OleDbConnection(strConn))
{
conn.Open();
OleDbDataAdapter adapter = new OleDbDataAdapter(strExcel, strConn);
adapter.Fill(ds, strSheetName);
conn.Close();
}
return ds.Tables[strSheetName];
}
三、向Access数据库表插入数据
public static void InsertDataToAccess(string _strPara,float _fPara)
{
OleDbConnection oleDbConn = new OleDbConnection();
oleDbConn.ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\ExcelData.mdb;User Id=admin;Password=;";
oleDbConn.Open();
string strInsertString = "INSERT INTO tb_excelData (strCollumn1,fCollumn2) VALUES (@strCollumn1,@fCollumn2)";
OleDbCommand oComm = new OleDbCommand(strInsertString, oleDbConn);
oComm.Parameters.Add("@strCollumn1", OleDbType.Char , 50);
oComm.Parameters["@strCollumn1"].Value = _strPara;
oComm.Parameters.Add("@fCollumn2", OleDbType.Double);
oComm.Parameters["@fCollumn2"].Value = _fPara;
ocomm.ExecuteNonQuery();
oleDbConn.Close();
}
