the for construct can be looked at like a while construct. Maybe this will help you understand it x=2; num = 100; while ( x < num ) { // do something with x x = x + 1; } Hope that helps. The modulus returns the remainder of the …

Funny, Just use == instead of =

Barefoot Unfortunately, you are dealing with fileIO and things will get slow. What you can try IMO is saving the information into an xml file, or SQL database. Then the next time you run the program it will load from the data store. Another thing to try is parcing the …

Try changing your code to this: [code] OleDbCommand myOleDbCommand_MemCount = myOleDbConnection.CreateCommand(); myOleDbCommand_MemCount.CommandText = "Select COUNT(emp) [B]as empCount[/B] FROM temp_table)"; OleDbDataReader myOleDbDataReader_MemCount = myOleDbCommand_MemCount.ExecuteReader(); if ( myOleDbDataReader_MemCount.Read() ) { Console.WriteLine("Number of Members: " + myOleDbDataReader_MemCount["empCount"].ToString() ); int Count = (int)myOleDbDataReader_MemCountl["empCount"]; Console.WriteLine(Count); myOleDbDataReader_MemCount.Close(); } [/code] You can also just use the 0 …

There are a few things for you to look at. Where the databases created using the "sa" administrator account ? IOW, who is the owner of the database, and was the Login account you are using to log in to the server have permission to use the new DB. The …

I have attached a project that does what you want. Parameters are passed on the command line. So if you set a File Association with your application, and double click it in the explorer, it will launch you application and pass the filename as a parameter. The example project determines …

I am also a convert from Delphi (started with D1, ended with D2005). There are many ideas out there on how to centralize your data. The idea of a Data Module is not as foreign to C# as you might think. After all, a TDataModule is nothing more than a …

Once the DataReader is closed, it is a null object. You need to reinitialize it as a new DataReader. stat = new SqlDataReader();

You need to convert the Hex back into an int then convert the into to a char. [code] string sHex = "41"; // same as 'A' [COLOR=green]byte[/COLOR][COLOR=green] newByte = [/COLOR][COLOR=green]byte[/COLOR][COLOR=green].Parse(sHex, System.Globalization.[/COLOR][COLOR=green]NumberStyles[/COLOR][COLOR=green].HexNumber);[/COLOR] [COLOR=green]// newByte now = "65"[/COLOR] [COLOR=green]int i = Convert.ToInt32(newByte.ToString()); // i now = 65[/COLOR] [COLOR=green]Char schar = [COLOR=green]Convert[/COLOR][COLOR=green].ToChar(i);[/COLOR][/COLOR] [COLOR=green][COLOR=green]// …

Sounds like another student homework assignment. We get lots of those up here. Anyway, study the modulus operator, and you will discover the answer.

I assume what you want to do is trap the Page Down key and use it for navigating the datagridview. The problem in your code is that you are not telling the datagridview that you have aleady handle the key press. Let it know that you have taken care of …

If I understand you right, you have some text controls on the form, and you want to iterate through each to look at their text value. Since all of them are already in the controls array, you can just iterate through them. You can rely on the name, or set …

Namespace declarations do not impact the resulting application. They are used by the pre compiler to locate code addressing during the compile phase. You could preface every object and type in your source code with its namespace, and all you are doing is beating up yourself. The c# compiler examines …

There seems to be a lot of gaps in your question, but I will take a stab at it. You have a load Game button and you need player 1 and Player 2 to login. I assume both login on the same form while it is open. Once both players …

Simply place a WebBrowser component on your form then pass it the URL WebBrowser.Url = TextBox1.text;

covertx, The str value you are passing to the delegate needs to be done a little differently. Invoke is an eventhandler type. That means it takes Sender and Params as the second argument. just like all other event handlers in c#. Params is an object array (like args). In your …

Another way of trapping the Enter key is by using the form's KeyPreview property set to true.

If you used the Min and Max methods from Java, then you can use the System.Math.Max and System.Math.Min methods in C# Otherwise create a sortable array, get the first and last elements. Hope that helps, Jerry

I think he means parameter not items. Parameters are pased to static methds in the same way that parametes are passed to private , public, etc methods. No special parameter syntax required.
