Forms :: Multi-line Textbox And KeyPress Event Unusual Behavior?
Aug 13, 2010
I have several multi-line textboxes that I want to lose focus (i.e. when the user presses the right arrow key) but the control wil not relinquish the focus.Simply put, I first verify if the selection start is at the end of the text, if it is, and the user presses the arrow key, it should move to the next textbox. some debug.print code placed in strategic locations indicates that the target textbox gets focus and immediately loses it and the source textbox gains focus once again. Essentially not allowing the textbox to lose focus.
Select Case
Case Keys.Right
tbRight.Focus()
[code]....
After changing the source textbox multi-line property to false, it behaves as expected. Is this a "feature" .. surely I don't have to resort to "SendKeys"
i know this has to be simple but i can find anything anywhere tonight on how to check if while a textbox has focus if the ctrl+v or ctrl+c was pressed i simply need to use it like such:[code]
a user copies multiple lines of text (say, from an email) into the clipboard. Based on my observations, when one tries to paste the text into a single-line textbox, only the first line is actually pasted in. (I am aware that the "obvious" solution would be to set the Multiline property to True, but there are reasons I am looking to avoid this and to put multi-line data into a single line.)
In the TextChanged event handler, I wrote code that parses the clipboard data to successfully convert it to a single-line, comma-delimited format.
Private Sub txtMassTrackingNo_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) _ Handles txtMassTrackingNo.TextChanged
This is a WinForm VB.NET application. Please see the picture below:How to add a line break in a multi line textbox in Visual Studio designer's property section?I tried using abc & Environment.NewLine & def but that was not working.
I have created the following piece of code to try and see if the user pushes the 'f1' key, and if they do.
[Code]...
I am not sure if this code works yet because the keypressed event is not triggered when I push a key. Could someone tell me how I can change my code so that it will test what key is pressed, no matter what control on the form has focus?
anyone know how to invoke the KeyPress event ? This code shows what I would like to do, but it simply calls the eventhandler and does not insert the text into the text box, so is not what I want/need.
Private Sub prices_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles wholeprice_input_new_item.KeyPress, dozenprice_input_new_item.KeyPress, detailprice_input_new_item.KeyPress, costprice_input_new_item.KeyPress
[code]....
I want to validate all the characters. How I can make the event keypress validate all characters in a text box?
I have the below code on the KeyPress event of a textbox howver a need has now come in meaning I have to do myTextbox.Text = "A input string"
Private Sub ChequeAmountKeyPress(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtChequeAmount.KeyPress Dim tb As TextBox = sender If (e.KeyChar = "." AndAlso tb.Text.Length = 0) Then e.Handled = True
[Code]...
This input string could contain a format that I do not want and whilst the keypress event caters for the need when the user is typing I need to handle it in the case of a text assignment.I thought firing the keypress event after I assigned the text property but I dont think that will offer what I want.
i have 3 multi textbox's .. and one button. it should lookup for the strings or numbers that available in the first textbox and not available in the second each string or number in new line.. and put it in the third on button click::

I have a web control in which I have a multiple line text box. I'm updating the contents of the text box using a timer_tick event. I want to display the last line of the text box every time the timer_tick event is fired.
I am writing a little 'macro' functionality into my multi-line textbox. All is ok except i don't know how to move the cursor up, or down, lines to simulate pressing the keyboard arrow keys (left and right are no problem). Obviously lines can wrap so using substring may be out?
I have a multi-line text box with hundreds of lines. I would like to be able to scroll up or down in the list using the mousewheel (much like using the pgup/pgdown keys). I think I need to use the .mousewheel event, but I'm not sure how to implement this. Is that supported out of the box, or do I need to hook the mouse?
So what happens is. I have this JAVA Code which i am making out of a vb form to help me develop quicker in that. So, when i click "Button1" a formula enhances and gives an output "TEXT" Which i want to choose what lines it shows on my "MultiLine Textbox".
Basically, How do i make it so when i click a BUTTON a text is written in a MULTILINE-TEXTBOX which i get to choose which bits of the text goes on which line.
the example is: ("this goes on line 1") ("this goes on line 2") ect.
Is it possible to move the cursor position in a multi line textbox? Here's an example; I have a form with a multi line textbox and a button. The button inserts several lines of [Code] How could I make the cursor go to the blank line between the parenthesis? [Code]
What I am trying to do here is search a multi-line textbox that contains the source of a particular website.what I would like is something like this but i do not know how to right it like i need
Dim MyString, FirstWord, LastWord, MidWords As String MyString = "Mid Function Demo" ' would be the textbox FirstWord = Mid(MyString, 1, 3) ' Returns "Mid". LastWord = Mid(MyString, 14, 4) ' Returns "Demo". MidWords = Mid(MyString, 5) ' Returns "Function Demo".
this function works fine only when you define len.what I need is a function that will do something like this, "note obviously interpreted code"
Dim text, A,B,C as string text = textbox1 A = "<body>" B = "information between A and C being of variable len" C = "</body>" textbox2 = B
I have redirected the results of the command prompt to a multi-line textbox and i want to get the line number of the error. [code] how would i get the line numbers? it should get 90,92,95.

[Code]...
the weird problem im getting is if i run my program and click the add button with the textboxes being empty it correctly changes the bordercolor to red but if i press the tab key it removes all the red bordercolors, why is this?i dont want the tab key to clear the red bordercolors.
how to redirect outputs from console to a window form text box,but the console application I'm using is always running real time, thus my .net application hangs until I close the program that is read real time.The code displays the application to a 2nd form with a textbox multi line. Until I close that my entire program hangs and the console application monitored runs.
How do I code it to:
1. Run real time without hanging the entire program.
2. the console app must run at all times. (figured how to hide/ and no window created for it)
Sub Console() Form2.Show() Dim myCon As New Process myCon.StartInfo.UseShellExecute = False
I have a multiline textbox from which I would like to read each individual line and store it in an array. I don't want to store each carriage return, I want the line itself.I have been using this, but it only records lines followed by carriage returns.
Dim arra() = txtReceipt.Text.Split(Environment.NewLine)
Here is a visual example: [URL]From that top right textbox, I would want arra(0) to be "Type some stuff here (and hit the return and" and arra(1) to be "tab keys...)"
In vb6, making small games came with a curse, if you pressed more than one key at the same time, they would cancel out. I went around it by making a boolean array to determine which keys were up, and which were down. anyways,
