You can add the contrast and brightness matrices, I guess, or you can apply one, then the other.

Hi,

I think you want a non-linear transformation, ideally something that maps all colors to either black or white. Maybe ImageAttributes.SetThreshold could help you out, provided you give it a good value, at best it would depend on the average brightness of your image,

you are asking a database ? in the C# forum.

In management studio, open the object explorer, right click on your database and there should be a Tasks menu item. Under here lies you tools.

Difference between commandtype.storedprocedure and commandtype.text in terms of speed.

I am writing a large data to MS access via reader.

I needed to change query from storedprocedure to text since I needed to create the database I was going to write. And I do not know to create a query in MS access via C#.

Now I recognized that the writing process slowed down significantly. Is it true that Stored Procedure works faster compared to commandtype.text.

Moreover do you know how to create query in MS Access via C#.

Thanks in advace

Not sure about Access Dead | X|

but there are lots of discussions regarding SQL Server[^] that have been going on for what seems like centuries.

IIRC there is not longer a dramatic difference between then (in SQL). In Access you are screwed before you start so it probably does not matter.

Passing SQL Statement --- What am I doing Wrong? ---

All I want the procedure to do is execute the sql statement that I pass it. I do not want or need any result to be passed back as the stored procedures will update or or insert to the tables.

private void SQLExecution(string WhatismyConnectionString, string MySQLStatement)
{
//This is the command I am passing in the SQL Statement...
//It is a stored procedure that simply does a deletion to the table.
//WhatismyConnectionString = "sp_vc_NoLongerExist + @MachineName + @UserName + @AppName"

SqlConnection conn = new SqlConnection(WhatismyConnectionString);
SqlCommand command = conn.CreateCommand();
command.CommandText = MySQLStatement;

command.CommandType = CommandType.Text;

// execute the command that returns a SqlDataReader
object returnvalue = command.ExecuteScalar();

MessageBox.Show("YEA?");
}

Open your connection

Commandtype should be command.StoredProcedure

Create parameter object and then define all your parameter and then add your parameter in command object as

command.Parametyer.Add(put your parameter object here)

And execute as ExecuteNonQuery command.ExecuteNonQuery

Thanks,
Atin

<DownloadedForms>
  <row>
    <CommunityCode>28-2801-0001</CommunityCode>
    <FormName>Form6</FormName>
    <FormPage>1</FormPage>
    <FormPath>c:\PDF Files\BAMYAN\Bamyan\28-2801-0001\Form6\28-2801-0001-F6.pdf</FormPath>

and the code to read the xml file is

XmlTextReader read=new XmlTextReader("xmltopic.xml");
			while (read.Read()) {
				
			}
			DataTable dt=new DataTable();
			dt.ReadXml(read);
			MessageBox.Show(dt.Rows.Count.ToString()); //returns 0 rows

Creating DataTable from XML DataTable

DataTable mytab = new DataTable();
mytab.ReadXml("c:\\myfile.xml");

To Read your XML file U have read it to a Dataset.
like
Dataset myds = new Dataset ();
myds.ReadXml("c:\\tt.xml");
Get your table from
myds.Tables[0].Rows.Count
