        }


UnZip the File

 string srcFile = @"C:\sample.zip";
        string dstFile = @"C:\file_xml1.xml";

        FileStream file_stream_in = null;
        FileStream file_stream_out = null;

Stored procedure for finding number days in month

Finding number of days in a month

alter procedure no_of_days as
Declare @no_of_days int
Declare @prev_month varchar(100)
Declare @current_month varchar(100)
Declare @file_duration varchar(100)
DECLARE @returnDate INT
declare @days int

SET @returnDate = CASE WHEN MONTH(getdate())
IN (1, 3, 5, 7, 8, 10, 12) THEN 31
WHEN MONTH(getdate()) IN (4, 6, 9, 11) THEN 30
ELSE CASE WHEN (YEAR(getdate()) % 4 = 0
AND
YEAR(getdate()) % 100 != 0)
OR
(YEAR(getdate()) % 400 = 0)
THEN 29
ELSE 28 END
END

Get previous month name and current month name

set @no_of_days=@returnDate
set @prev_month=(Select Datename(mm, GetDate()-@no_of_days))
set @current_month=(Select Datename(mm, GetDate()))
set @file_duration=@prev_month+'-'+@current_month

Code for Copying Sql Table data into Excel file

Step 1:

Before run this procedure u have to create a excel template file with the relevant column name of the table.

Step 2:

Create PROCEDURE SP_Sql_Excel @File_Name as varchar(50) = ''
AS
BEGIN
    SET NOCOUNT ON

    DECLARE @Dos_Command varchar(1000)
    DECLARE @reportname varchar(500)
    DECLARE @Oledb_provider varchar(100)
    DECLARE @Excel_String varchar(100)

--    New File Name to be created
    IF @File_Name = ''
        Select @reportname = 'C:\temp\Excel\Template1.xls'
    ELSE
        Select @reportname = 'C:\temp\Excel\' + @File_Name + '.xls'

--    FileCopy command string formation
    SELECT @Dos_Command = 'Copy C:\temp\Excel\Template1.xls ' + @reportname

--    Execute Dos Copy command
    EXEC MASTER..XP_CMDSHELL @Dos_Command, NO_OUTPUT

--    Mentioning the OLEDB povider and excel destination filename
    set @Oledb_provider = 'Microsoft.Jet.OLEDB.4.0'
    set @Excel_String = 'Excel 8.0;Database=' + @reportname

--    Executing the OPENROWSET Command for copying the sql data  contents to Excel sheet.
exec('insert into OPENrowset (''' + @Oledb_provider + ''',''' + @Excel_String + ''',''SELECT username,password FROM [Sheet1$]'') select username,password from login')

SET NOCOUNT OFF
END



Step 3:

Run the Procedure


Exec SP_Sql_Excel 'filename'

Code for Download a file from a folder

string[] filepath = Directory.GetFiles(Server.MapPath("~\\upload files"));
            foreach (string fileName in filepath)
            {
                string filename_read = Path.GetFileNameWithoutExtension(fileName);
                if (hidden_tar_file.Value == filename_read)
                {
                    System.IO.FileInfo file = new System.IO.FileInfo(fileName);
                    if (file.Exists)
                    {
                        Response.Clear();
                        Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name);
                        Response.AddHeader("Content-Length", file.Length.ToString());
                        Response.ContentType = "application/octet-stream";
                        Response.WriteFile(file.FullName);
                        Response.End();

coding for connectoin remote desktop using c#

Process process_conectoin = new Process();
string exe = Environment.ExpandEnvironmentVariables(@"%SystemRoot%\system32\mstsc.exe");
if (exe != null)
{
process_conectoin.StartInfo.FileName = exe;
process_conectoin.StartInfo.Arguments = "/v " + "192.168.1.2"; // ip or name of computer to connect
process_conectoin.Start();
}
