I got a Sub which processes a code, and then it does whatever the code said. Example.
Code = "Black" -> Turns screen black.
Code = "OFF" -> Turns off the PC.
And so on.
If I call that Sub from Immediate console, It works perfectly. But if that Sub is called from an event, It does nothing, and usually throws an Exception. I read somewhere that I can fix this by using Threads, but I don't understand how that can help and make it work.
I have created a form to update an access DB table. My issue is that when the text in the text boxes is changed and the form is submitted, the .text values stay the same as they were when the datareader loaded them on the page load event. How can I submit the values that the user updates, not what is already there from page load.[code]...
I'd like to detect a textbox change but only take an action after it is completed.
The problem is the number which is four digits is changes one number at a time so a normal text changed event will be forever logging a change. Ideally it would detect the change and only display a popup 5 seconds after the change is completed (ie no further changes detected!)
On the KeyDown event of the textbox, i need to capture the character pressed and send it to a function which fires a sql query for this character.To get the character i am using Convert.ToChar(e.keycode).However Convert.Tochar converts the keycode to char according to its ASCII value , thus F4 gets converted to "s" as "s" has ASCII keycode of 115.Is there some other way to convert the keycode to character which won't make these wrong conversions as even if i restrict the functions keys there may be problem with other key conversion also.
I have a form with over 100 textboxes that are set in multiple groupboxes and that number grows as I continue working. I am trying to get an event to fire if there is a keydown on any one of the textboxes. other than individually adding all 100 textboxes to the handler, is there a way for me to create a single event that handles all textbox.keydown events on the form?
I want to run something like the code below every time a textbox on my form changes. The code rules out text boxes within groupboxes that I don't want to fire.
If TypeName(SplitContainer1.ActiveControl) = "TextBox" and InStr(ctrl.Parent.Name, "GroupP1Payoffs") = 0 _ and InStr(ctrl.Parent.Name, "GroupP2Payoffs") = 0 and InStr(ctrl.Parent.Name, "GroupP1LoanDetails") = 0 Then
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]
So I am playing around with the resize event. My form is 500 wide, my button.left is at 100. If I use: Dim int As Double int = button1.Left / Me.Width ' this = 0.2 'resize event 'Button1.Left = (int * Me.Width) TextBox1.Text = (int * Me.Width).ToString The number in the texbox is correct - proportion wise, but it won't set the button1.Left to this number. I'm sure this is because int is a Double where .Left is an integer?
I've got a Windows Forms with some Textbox's and I'm trying to make a one of them which can automaticly (or if you press Enter) change letter D to today's date, to make user life easier.
OK, so my project is like this:The user selects a folder from their computer that holds a list of subfolders. The program then dynamically inserts a check boxes per subfolder within a seperate cell of a Table Layout Panel.I want to and a simple Click event to each checkbox control so that when a control is clicked, it counts all of the check boxes on the form that are checked.How do I go about adding the event handler to the checkboxes when they are created. Here is the code that adds the checkboxes:
Dim iCol As Integer = 1 Dim objFolder As Object = Nothing For j = 0 To rCount - 1 '0 to dynamic number of rows
i want to set Arabic language to some textbox in my form.in Access its a property but its not exist in VB.net 2005 how can i change the Input language when i enter my textbox?
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 want to create a textbox which contents are validated every time the text in it changes. And an image is displayed beside the textbox if it is correct and another image shows up if its not correct. Pretty much like ajax.

I am using Visual Basic 2008 I am trying to capitalize words in a text box. I am using the following code (which, in case you don't recognize it, came from an example which I modified):
Public Sub FuncKeysModule(ByVal value As Keys) 'Check what function key is in a pressed state, and then perform the corresponding action. Select Case value
[code]....
In the application, I select a word in the textbox then hit F2. The text is pulled from the textbox, I manage to change the first letter to a capital letter BUT I cannot change the textbox.I already set the ReadOnly property of the textbox to False when I initialized the textbox. It looks like the Replace function does not work.
