add [icode]openFileDialog1.MultiSelect = true;[/icode] after line 27. And in line 31 you are going to have to pass the file names to your intelhextobin method.

How is the web browser control messing up your application is what I'd like to know :) Have you tried handling the Navigating event and setting the Cancel property to true?

This will do what you want. It's an extension method to the class StreamReader:[code]using System; using System.IO; using System.Text; namespace ExtensionMethods { static class Extensions { public static String ReadLine(this StreamReader sr, char c) { StringBuilder sb = new StringBuilder(); int character; if (sr.EndOfStream == false) { do { character …

Problem is that you are trying to insert a string into a decimal field in the database. Remove the single quote (') marks from your SQL statement or learn to use [URL="http://dev.mysql.com/doc/refman/5.0/es/connector-net-examples-mysqlparameter.html"]Parameters[/URL]

[QUOTE=thines01;1623797]Inside your ChangeCase method, I would convert the string to a CharArray [/QUOTE] There is no need to do this. You can treat a String as if it was already a character array.

Here is an example I wrote using a CheckedListBox, a Label, and a Button: [code]using System; using System.Collections.Generic; using System.Windows.Forms; namespace WindowsFormsApplication1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); List<MyData> data = new List<MyData>(); checkedListBox1.Items.Clear(); for (int i = 0; i < 10; i++) { …

Run it outside of Visual Studio and check if it inserts the record.

[code]foreach (int item in checkedListBox1.CheckedIndices) { checkedListBox1.SetItemCheckState(item, CheckState.Unchecked); }[/code] Selected and Checked are two different states so that is why your code doesn't work. There isn't an easier way.

Try using [icode]reader["someField"].GetInt32()[/icode]. I'm not sure if the MySql connector supports indexed columns this way, so you may have to use [icode]reader.GetInt32(<column number of "someField">)[/icode] i.e. [icode]reader.GetInt32(4)[/icode].

Can you translate the message into English? Does it say something about connection already in use?

It's awkwardly worded. When you call the print method on the p2 object, you technically are calling that classes method. When you call it on the p1 object, you are 'overriding' the base class method with the derived classes method.

By writing code to read the video files and combining them. This is a vague question which leaves a lot out. What type of files? Do you have a codec for the files or do you have to write your own? What do you mean by 'join'? What have you …

We image the drive then restore it when needed. I'm not sure if there is any free drive imaging software out there (well, there is [URL="http://www.runtime.org/driveimage-xml.htm"]here[/URL]. It's best to make the testing partition as small as possible as this will speed up the restore (you only need to image once).

Depends on what you mean by delete and what type of file. For example, I have a text file with lines in it like these: [code]Line 1 Line 2 Line 3 Line 4[/code] I delete "Line 2" do I get:[code]Line 1 Line 3 Line 4[/code]or[code]Line 1 Line 3 Line 4[/code]

I know this is closed already, but it says in the C# standard "Bitwise operators are predefined for int, uint, long, and ulong", and this is why the byte is cast into an Int32.

If you open a connection to the database, .NET actually opens multiple connections to that database (the connection pool). This is done to speed up future connections (in your program) that you might need. Even if you close all your connections, .NET maintains its open connections in case you might …

You do want tables for Team and Card Comp with IDs linking from the main record. ID (a number) is at most 4 bytes. A team name can be much longer and you'll save space. Also, if you tell the database to index on the ID field, searches will be …

[code]byte[] myData = File.ReadAllBytes("Some.exe"); myData[2342] = 0x00; File.WriteAllBytes("Some.exe", myData);[/code]

Ok, the first problem ('a' + i). The compiler sees that i is an Int32 so it casts the character 'a' into an Int32 and does the add. The (char) outside the math converts it back into a character. Second problem. The logic truth table for AND is [CODE]Bit 1 …

Line 5 makes a lot of assumptions (there will be ContentErrs and TestID and Errors and Error). I'd break that up into individual checks [code]IEnumerabel<XElement> contentErrs = doc.Root.Elements("ContentErrs"); if (contentErrs != null) { ...[/code] Something like that.

Of course it only happens one time, you have no loop construct in your code to make it happen more than once (no for, no foreach, no while or no do/while). And that is some really ugly code. Do you know what an array is? Step back a bit, learn …

No, 600 isn't the limit for the size of an array. Without seeing your code I can't tell you why you are exceeding your array size.

We need a lot more information than "it's telling me Error". What error, exactly, is it giving. What line, exactly, is the error occuring. You should catch specific exceptions, not the generic "catch" you are using. You don't even bother to get the exception object so you can see more …

you are trying to assign a string ("Price") to a decimal field. Is Price a variable in your code? If so, remove the quote marks. If not, you need a decimal value to assign to it.

Why do you need to serialize a byte array into a byte array (which is what Binary Formatter really is)? Just transfer the array, don't serialize it.
