VB NET 2010 CONSOLE APPLICATION CHECK INPUT IS LIKE STRING CODE
The button code reads the data it needs from the controls and does something with it. In a form, you enter data into all the controls necessary, then press a button. Data entry isn't sequential like it is on the console. Normally, if you want two different things, you will add two different textboxes. Instead of reading the console, you will read the test from textbox.Text (with whatever your textbox name is, of course).

If you will be writing a whole series of things, you might also consider adding a Listbox, and adding strings to that listbox to display your text.Īny place where you use Console.ReadLine, you want to replace that with the textbox.Text property. Whether you use one label and keep replacing the text (you won't like that in practice), or one line and keep appending text (busy and hard to format), or use a different label for each item to write, is up to you. Let them enter whatever they want and perform all action in the Search_Button_Click event handler.Īny place you have Console.WriteLine you want to be writing to the. There is no chance that they will have a valid site after they type the first character, nor the second, and so on. That would mean checking something for every character the user typed including a backspace.
I wouldn't do anything in the TextChanged event. When I then format it into yyyyMMdd to feed into SQL, an exception is thrown. The user may input 1-1-201 and it will be accepted as a valid date (IsDate also accepts this). If you are going to continue down that road, you probably ought to PM a moderator and ask them to move this to the C# forum. In lots of places, I have a check like: If Date.TryParse(MyDateTextBo x.Text, New Date) Then This, however, wont work properly. Well, for one thing, you are clearly writing C#, not VB. If (MessageBox.Show("Do you really want to quit?", "Quit the program?", MessageBoxButtons.OKCancel) = DialogResult.OK) Private void finish_button_Click(object sender, EventArgs e) Private void returnIP_TextChanged(object sender, EventArgs e)įor (int i = 0 i < address.Length i++) // output list of IP address IPAddress address = IPHost.AddressList // get list of IP addressĬonsole.WriteLine("List IP :", IPHost.HostName) IPHostEntry IPHost = Dns.Resolve(strHost) // though Dns to get IP hostĬonsole.WriteLine(IPHost.HostName) // Output name of web host Private void search_button_Click(object sender, EventArgs e)
Private void iphere_TextChanged(object sender, EventArgs e)Ĭonsole.Write("Input host : ") //Iput web host name as string After all, if they don't enter anything, then press the button, it would be just an invalid site anyways, so you would handle it like any other. There is a small amount of additional code that you might want, which would make sure that the user actually entered something in the textbox, but it probably doesn't matter. In the first button, which you can give whatever caption you want, you put pretty nearly all the other code, except that you probably want another label on the form to hold the output. The label should probably be added so that it looks like a caption to the textbox, so either put it at the same level and to the left, or above and on the left side, of the textbox. Where you have Console.Write you would have a label. The first button is where the bulk of that code goes, and the second button is just a FINISHED button with the code: Me.Close. Add a textbox for the user to enter the website, and two buttons. That should give you one default form, which is all you need.
