Sometimes you need to have a C# windows form application run in full screen mode.  Like you see on a kiosk at a mall or some stand alone machine.  It's fairly easy you just need to set some of the properties on the Form either in it's OnLoad method or directly in the designer. In the OnLoad method of the main Form set these values, or again set them directly in the designer. this.MaximizeBox = false; this.TopMost = true; this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None; this.WindowState = System.Windows.Forms.FormWindowState.Maximized;

In C# I have read a lot of debate over which way is the best way to do String Concatenation.  I have often read never ever use String1 + String2 due to the memory allocations and time constraints.  I decided to run some tests on the various way of doing String manipulation.  The table below shows the iterations, total times, and average times for some common way of doing string addition.  This was just a test of time, there was no memory consumption test.  All tests were doing adding 7 strings together that were stored in variable names.  There was no string a = "a" + "b";  It was all string a  = var1 + var2;  These were creating a single string for the listed iterations using the method(s) below. I was surprised to see the + method came out ahead in all the tests.  String builder came in a close second.  String.Format was extremely slow but allows for localization which is another story. iterations String + average ...

When you fill a DataSet/Table in C# you use a SQL Data Adapter. The code for this is geared towards a SQL SELECT statement. However I'm not a big fan of raw SQL in my code so I found a way to use a stored procedure instead. public static DataTable GetTable() { DataTable dt = null; try { using( SqlConnection connection = new SqlConnection( "your connection string" ) ) { using( SqlDataAdapter sda = new SqlDataAdapter() ) { using( SqlCommand command = new SqlCommand( "your stored procedure", connection ) ) { command.CommandType = CommandType.StoredProcedure; // this line needs to be added for every parameter the SP expects command.Parameters.AddWithValue( "parametere value", paramValue ); sda.SelectCommand = command; dt = new Da...

Below we have some code that opens a connection to a database using a connection string then executes a stored procedure. This obviously needs to be placed in some method or class. You will need to add your own connection string and parameter values. try { using( SqlConnection connection = new SqlConnection("some connection string" ) ) { using( SqlCommand command = new SqlCommand( "stored procedure name", connection ) ) { command.CommandType = CommandType.StoredProcedure; // this line needs to be added for every parameter the SP expects command.Parameters.AddWithValue( "parametere value", paramValue ); connection.Open(); // based on the what the SP does, call the execute non query, execute scalar, or execute reader method command.ExecuteNonQuery(); } } } cat...
