System.IO.FileSystemInfo helps you http://msdn.microsoft.com/en-us/library/system.io.filesysteminfo.aspx

//Global Variables
Form frmChild;

private void button1_Click(....)
{
//show child form
frmChild=new Form();
frmChild.MDIParent=this;
frmChild.Show();
frmChild.FormClosed+=new FormClosedEventHandler(frmChild_FormClosed);
//disable your button
button1.Enabled = false;
}

void frmChild_FormClosed(object sender, EventArgs e)
{
button1.Enabled = true;
}

Please clarify, where the button is? Parent Form or the Child one? and tell me the exact scenario.

So, you have Child Form which opens from the button... you'll implement the event Form Closed of the Child Form to execute this piece of code

yourButton.Enabled = true;

Work with MemoryStream it may help to separate your operations and the physical file.

Reasonable! :) should have typical copy on temp folder and work on it, if your operation successed then you delete the original one.

System.IO.File.Delete(FilePath);

Handle Keypressed event of the textbox

private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
        {
            char lastChar = e.KeyChar;
            //MessageBox.Show(((int)e.KeyChar).ToString());
            if (e.KeyChar != 32 && e.KeyChar !=8) //allows space and backspace
            {
                if (char.IsControl(lastChar) || char.IsDigit(lastChar) || char.IsNumber(lastChar) || char.IsPunctuation(lastChar))
                    e.Handled = true;
                else if (lastChar < 1575)//the start of ascii codes for Arabic chars.
                    e.Handled = true;
            }
        }

Paul... I didn't get where you stuck.. but if you need tutorial guide I recommend this http://functionx.com/adonet/index.htm

What type of database are you using?

Thread name SQL in C# :)

Trust me, it works :) please mark it as solved.

Post what you don't understand...

http://www.c-sharpcorner.com/UploadFile/mahesh/printfile06062007133250PM/printfile.aspx

Copy the code!! or make it reusable control and drag it and drop it wherever.

Because of spaces man...

public void WriteDataToFile(MeetingEntry currentEntry)
        {
            OleDbConnection dbConnection = new OleDbConnection(CONNECTION_STRING);
            
            string commandString =
            "INSERT INTO MeetingEntries (Subject, Location, [Start Date], [End Date], [Enable Alarm], [Repeat Alarm], Reminder, [Repetition Type])" + " VALUES (@Subject, @Location, @StartDate, @EndDate, @EnableAlarm, @RepeatAlarm, @Reminder, @RepetitionType)";
            //"INSERT INTO MEETINGENTRIES (SUBJECT, LOCATION, START DATE, END DATE, ENABLE ALARM, REPEAT ALARM, REMINDER, REPETITION TYPE)" + " VALUES (?, ?, ?, ?, ?, ?, ?, ?)";
            
            OleDbCommand commandStatement = new OleDbCommand(commandString, dbConnection);
           

            commandStatement.Parameters.Add("Subject", OleDbType.VarWChar, 30).Value = currentEntry.Subject;
            commandStatement.Parameters.Add("Location", OleDbType.VarWChar, 50).Value = currentEntry.Location;
            commandStatement.Parameters.Add("StartDate", OleDbType.Date, 40).Value = currentEntry.StartDateTime.Date;
            commandStatement.Parameters.Add("EndDate", OleDbType.Date, 40).Value = currentEntry.EndDateTime.Date;
            commandStatement.Parameters.Add("EnableAlarm", OleDbType.Boolean, 1).Value = currentEntry.IsAlarmEnabled;
            commandStatement.Parameters.Add("RepeatAlarm", OleDbType.Boolean, 1).Value = currentEntry.IsAlarmRepeated;
            commandStatement.Parameters.Add("Reminder", OleDbType.Integer, 2).Value = currentEntry.Reminder;
            commandStatement.Parameters.Add("RepetitionType", OleDbType.VarWChar, 10).Value = currentEntry.Repetition.ToString();
            
            
            dbConnection.Open();
            commandStatement.CommandText = commandString;
            commandStatement.ExecuteNonQuery();
        }

please clarify or tell us the scenario...

From program.cs

/// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new Form1());//the name of the form :)      
}

Application.Run(new Form1());

So please attach here your application with the database, so I can help you better

It means the query run on Access database "INSERT INTO MeetingEntries (Subject, Location, Start Date, End Date, Enable Alarm, Repeat Alarm, Reminder, Repetition Type) VALUES (?, ?, ?, ?, ?, ?, ?, ?)" which is wrong!

foreach(Control c in tableLayoutPanel1.Controls)
{
if( c is TextBox)
c.Text = null;
else if (c is CheckBox)
c.Checked = false;
else
//.....
}

Man! please read what I posted please commandStatement.CommandText in debug mode will show you the command gonna be executed! take it copy and paste in access and run it.

Please before commandStatement.ExecuteNonQuery(); get the commandStatement.CommandText and execute the query into access. see if it runs or not.

Can you please show us the exception?

or try currentEntry.EndDateTime.Date.ToShortDateString();

What do you mean by Clear the table layout? to reset all controls value i.e all textboxs Text property = null or to set the visibility = false
You can access all TableLayoutPanel controls by tableLayoutPanel1.Controls

To solve it and I assume taxableIncome is TextBox or Label

taxableIncome.Text = Convert.ToDouble(userValueTB.Text).ToString();

What's taxableIncome? please use code tags!
To solve second error

taxLBL.Text = Convert.ToDouble(taxLBL.Text).ToString();

Use AddRange method instead

ListBox2.Items.AddRange(ListBox1.Items);

If you're newbie.. please read in generics, arrays, and files
Generics http://msdn.microsoft.com/en-us/library/512aeb7t(VS.80).aspx
Arrays http://msdn.microsoft.com/en-us/library/aa288453(VS.71).aspx
File http://msdn.microsoft.com/en-us/library/system.io.file(VS.80).aspx

http://bytes.com/topic/c-sharp/answers/722688-codedomprovider-createcompiler-obsolete-fix

use generics...

List<string> personsData = new List<string>();
string personData = "name,phone,number,postcode";
personsData.Add(personData);
//use System.IO.File class to store personsData content...

Zizi, please take a look on the examples above the code...
First Parameter the string, second one the set, and third you tell the method select to not show first\second\etc.. string from the set..

That's great :) I develop small method do that work you may use Regular Expression but I prefered to write my code...

MessageBox.Show(Zizi("aABD", new string[]{"A", "B"}, 0)); // No A
MessageBox.Show(Zizi("aABD", new string[] { "A", "B" }, 1)); // No B
MessageBox.Show(Zizi("aABD", new string[] { "A", "B" }, 0,1)); //No A nor B
MessageBox.Show(Zizi("aABD", new string[] { "A", "B" }, 2)); //A and B

 private string Zizi(string str, string[] set, params int[] whatToNotCome)
        {
            string output = str;
            for (int i = 0; i < set.Length; i++)
            {
                if (whatToNotCome.Contains(i))
                    output = output.Replace(set[i], null); 
            }
            return output;
        }

Got the idea or I should explain my code...?

I don't get your rule! can you please guide me with more examples to recognize its pattern

To be aligned I'll illustrate what I got you mean you want to get distinct characters from string into array
Ex.
Input: RAMY MAHROUS
Output: {R A M Y H O U S}
correct?

Let's start it over...

string fileData = File.ReadAllText(@"file path");
checkedListBox1.Items.AddRange(fileData.Split(new string[] { "\r\n" }, StringSplitOptions.RemoveEmptyEntries));

Debug, because I'm pretty sure it don't enter "if" block //no condition
because DialogResult.No should be DialogResult.Cancel
Please try it..

Then you neeed to download LINQ SDK for VS 2005 http://www.microsoft.com/downloads/details.aspx?familyid=1e902c21-340c-4d13-9f04-70eb5e3dceea&displaylang=en

Something I begun to note is most of askers ignore my reply... and even don't comment, what does it mean????!!!
@papanyquiL didn't you see my reply?? or I should clarify?? or you aren't satisfied with the code??

This piece of code enumerate on the local drives then gets it root path then search for every exe on you can use SystemFileInfo to handle nested directories...

foreach (System.IO.DriveInfo dirveInfo in System.IO.DriveInfo.GetDrives())
            {
                foreach(System.IO.FileInfo fileInfo in dirveInfo.RootDirectory.GetFiles("*.exe"))
                    ///add the exe in list or handle it as you like
            }

I learnt a lot from this threadm thanks thanks thanks

File | You may use Move method in System.IO like that

System.IO.File.Move(@"C:\old.txt", @"C:\new.txt"); //it renames the file old to new.txt

Folder | the same

System.IO.Directory.Move(@"C:\oldfolder", @"C:\newfolder");

So please send your class code you want to group and order it; the class has this struct to play with this problem.

Why ArrayList?! Are you fond of casting??
Use generics List<Photo> photos = new List<Photo>(); and in Photo class you may have list of photos and indexer to get them by index or name anything is unique..

On the ComboBox double click, VS created a handler for index changed event copy and paste your code, and solve any error if exists..

var col = from le in mylist
group le by le.X into g         
orderby g.Key descending
select g;

On two phases

var colGrouped = from le in mylist
group le by le.X select le;

var colOrdered = from colGrouped ..... orderby...

LOL! did you read my reply??!!

There's events detect that
TextBox | TextChanged
ComboBox | SelectedIndexChanged

I see it's very simple in design and this is good, if it does its functionality well so you don't over care about its design.

Nice work, Diamonddrake

You just need to close the code tag.
You should have another property holding image file path

public string ImageFilePath
{
get...
set....
}
public Image Imge
{
get
{
try
{
return _Imge;
}
catch
{
Bitmap bm = new Bitmap(100, 100);
Graphics g = Graphics.FromImage(bm);
g.Clear(Color.WhiteSmoke);
Pen p = new Pen(Color.Red, 5);
g.DrawLine(p, 0, 0, 100, 100);
g.DrawLine(p, 100, 0, 0, 100);
return bm;
}
}
set {
using (Image _Imge = Image.FromFile(ImageFilePath))
Imge = value;
}
}

Set the ImageFilePath first...

Try to group first then order second

There's events detect that
TextBox | TextChanged
ComboBox | SelectedIndexChanged
