I did an example code which populates dgv from a dataSet, and then gets the selected row`s data, and passed them to form2`s textBoxes. In my example I only have 2 column in the dataSet (as in dgv of course) and 2 textBoxes to populate on form2. Take a look, …

Try doing a loop through foreach control of the form: [CODE] private void Insert() { foreach (Control c in this.Controls) { if (c is TextBox && c != null) { string valueOfTextBox = c.Text; } } } [/CODE]

This should do it: [CODE] public partial class Form1 : Form { private int wordIdFunc; public int propWordId { get { return wordIdFunc; } set { wordIdFunc = value; } } public Form1() { InitializeComponent(); } public string Word() { string[] words = new string[4]; words[0] = "The"; words[1] = …

For having images in the listView (on in some other control), best way is to use an ImageList. You put images inside, and from there show images in listView. For example, how to get images form a disc, send then to imageList and then to listView: [CODE] //for better accurecy …

Sure, you cannot show an array in a messageBox (its like putting a string array into stirng - cant do). You have to get all values from an array into a string, then show it in messageBox: [CODE] string[] myname = new string[2]; myname[0] = "Shahid"; myname[1] = "Hussain"; string …

Foreach is a loop. So you cannot assign it to read for one string. You did like: [CODE] string a = "a"; foreach(string b in a){} //this is an error! [/CODE] You have to do it like: [CODE] string[] array = {"a", "b"}; foreach(string b in array) { //get each …

Try using SelecredIndices collection: [CODE] public Form1() { InitializeComponent(); //my test population: char[] array = "abcdef".ToCharArray(); for (int i = 0; i < array.Length; i++) listBox1.Items.Add(array[i]); listBox1.SelectionMode = SelectionMode.MultiExtended; } private void button1_Click(object sender, EventArgs e) { while (listBox1.SelectedIndices.Count > 0) listBox1.Items.RemoveAt(listBox1.SelectedIndices[0]); } [/CODE]

How will dataSet show some value from it, if its empty. YOu have to retrieve the value from dataSet to textBox, after its being populated. So put the code from 4th line, bellow the line where you do the filling ("Fill()" method). If this is not it, tell more about …

Tabular? Whats is this? Does the dataGridView control satisify your expectations? So, back to your issue. Get wanted values from database( use DataTable to fill it up), then open Form2 (new pop-up window) and pass dataTable parameter to it (it can be passed in the constructor of form2). Then bind …

As darkagn said. Heres an example: [CODE] private void PopulatingTextBoxes() { int id = GetNewId(); textBox1.Text = id.ToString(); } private int GetNewId() { int id = 0; using (SqlConnection sqlConn = new SqlConnection("ConnectionString")) { string query = "SELECT (MAX)ID FROM STU"; SqlCommand cmd = new SqlCommand(query, sqlConn); using (SqlDataReader reader …

Something lke that? [CODE] private void method() { const int value = 5; string tag = "_"; string item = ""; for (int i = 0; i < value; i++) item += tag; MessageBox.Show("You have chosen " + value.ToString() + " underscores.\nThe result is: \"" + item + "\""); } …

I have changed the code a bit, with using virtual and override. And did some small changes also. Take a look: [CODE] class Program { static void Main(string[] args) { Student s = new Student("Dave", 1234); s.Birthday(); s.Print(); Console.ReadLine(); } } class Person { protected string name; protected int age; …

Momerath already showed you how to use properites. This how you have to do: [CODE] public partial class Form1 : Form { private int n; public int N { get { return n; } } public Form1() { InitializeComponent(); this.StartPosition = FormStartPosition.CenterScreen; } public void Increment() { n = n …

Hi, go to form designer, click on form, so the form`s border will have the focus. Now go to Properties window. There you will see a property called Icon. Select it, and click on button on the right. The "OpenFileDialog" will open and simpy look for your icon, and click …

You can hind Form1, and open form2. [CODE]//on button click: Form2 f2 = new Form2(); this.Hide(); f2.Show();[/CODE] If you will close or dispose Form1, the whole application will close, thats because in Program class you called "Application.Run(new Form1());" so this holds up everything.

No where. You can simply use an usual method, instead of cnstructor. Something like: [CODE] //on class1: Class2 c2 = new Class2(); c2.DoOnBeginning(); //on Class2: class Class2 { pubic Class2() { //constructor of class2 (its empty - but in use now) } public void DoOnBeginning() { //do some code! } …

My this code: [CODE] while (reader.Read()) { if(reader.GetValue(0) != DBNull.Value) listAtt.Items.Add(reader.GetValue(0).ToString()); //or better coding to get value: //listAtt.Items.Add((string)reader[0]); } [/CODE] This should do it. Mitja

Look at this code how it should be done: [CODE] public partial class Form1 : Form { List<string> list; BindingList<string> bindingList; public Form1() { InitializeComponent(); string[] array = new string[] { "A", "B", "C" }; list = new List<string>(array); bindingList = new BindingList<string>(list); listBox1.DataSource = bindingList; listBox1.SelectedIndex = -1; } …

You have to get the x,y location point of the control above.Then add to the "y" the height of this control and + 20. In my example, your new Control is my label, and my listBox is your BerichtInput: [CODE] int x = listBox1.Location.X; int y = listBox1.Location.Y; y = …

I will show some other way of using Threads and using boolean variable to stop it! Using thread.Abort() method is not a graceful way of stoping the thread. Not that its not correct (it does what its meant for), but there is a better any more appropriate way, as said, …

btw, why do you need a timer in the code? I did what I thought you want. Tell me if this is it.
