I know i can't create an array of objectsVB but i can make a collection of them. I have 15 textboxes and I want to create a sub that will handle all 15 textboxe's keydown event. I don't want to create a sub and call it from each textboxe's keydown event. Is this possible in anyway? can I handle the keydown event in one sub for all objects in the same collection?
View 8 RepliesI have multiple textboxes which I want them to perform the same thing upon clicking them. By default I can use the handles textbox1.click for 1 single textbox as shown below but I am not sure how to do handle multiples of them. Of course I can write a handler for every single textbox but I have about 50 of them. I am sure there must be a more efficient way. [Code]

I have an array, and I want to split the contence into textboxes. I have written some code to do so, but it won't work and I can't figure out what's wrong with it.

7 textboxes, 7 values, well not always as the textboxe might contain nothing
What im trying to do is add up the textboxes and return the value(total) in the array where am i going wrong??

Can anyone tell me how I would declare an array for data that will come from textboxes? Every example I find seems to be data that comes from an input box, and the array name would just be strInputbox, for example. However, in my case the user will input data into several textboxes (each named txtBox1, txtBox2, txtBox3, etc.) and I'm not sure how to write this.
Thank you.
When my form loads i create an array of richtextboxes. Since they're created dynamically i don't know how to do events like, textchanged or click, for each richtextbox. I'm pretty new to vb and to the forum. I'm not sure if i've posted this in the correct place on the forum if not apologies.

Dim str As String = "str1,str2"

i have 5 textboxes. i want to fill just textbox1 and textbox2 with array value. because no i have to word.but when i run the code "str1" repetition on textbox1,textbox2 and textbox3.
I so far have created a randomizer in Virtual Basic 2010 that:Takes people's names that the user imputed in form2 into an array (split by spaces).Randomizes the array Displays the array with a consecutive number and period behind it for each name that was imputed.
Here is the source code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim names() As String
Dim i As Integer

Pay attention to the last bit. I want to take the variable txt and split it. Then I want to take the first 10 names and display them in RichTextBox1, take the next 10 names and display them in RichTextBox2, and display the last 10 names in RichTextBox3.
I'm creating an array of textboxes using this code, (x number of textboxes)

I need to sum the values of each textbox, but only if there is a value in it. I have error checking elsewhere so that isn't the issue. It keeps giving me an error saying "Object reference not set to an instance of an object."
this is how I set up my data object for a file parser. (
Dim mytable As New List(Of String(,))()
mytable.Add(New String(4, 16) {})
and it loads mytable like this:
mytable(x)(y, i) = sToken(i)
Let me explain the indices, I have a form with a tab control. In mytable,x is the tab number. Each tab has up to 5 groups which is y. Each group has 17 text boxes, i.Each group also has 17 labels.I started looking at Me.controls, and looking at control properties like tabindex for some way to iterate through the textboxes and mytable to load the textboxes.
so I started with:
for x = 0 to 31
msgbox(group1.control(x).text
next x
and I saw how all my objects are not in sequence as it descending halfway through my label controls, then switched to my textboxes, and then seemingly finished randomly. I am at a total loss without the old index property and what I want to do is something like (forgive my syntax)
Form(0).Tab(x).group(y).textbox(i).text = mytable(x)(y, i)
I was thinking of manually setting the tabindex of all textboxes in group1 to sequential order to try something like:
group1.component.tabindex(i).text = mytable(x)(y, i)
To me this is fun and challenging, but also very frustrating and makes me miss coding in assembly As I can't seem to find any reference to the tree structure of accessing components indirectly, if that makes sense.
I've tried following the Microsoft instructions to add multiple Textboxes to my form, but just cannot get it to work.Thus, I've deleted everything I wrote, so I don't have code to post. Is there a very simple way to add multiple TextBoxes to a form and be able to index them? If it's too lengthy, Is there a workaround?

"Indexing" an array of textboxes - Control Arrays in VB2008
View 4 RepliesOn my form, i've got some textboxes and some richtextboxes. I'm using the following code, to search through the text properties of each of the two types of control. see below:-
For Each ctl As Control In Me.Controls
If ctl.Text = "7777" Then
ctl.Text = "found the sevens"
End If
Next
What i'd like to do is isolate the textboxes only, is there a way to do that? I tried this but i got an error:-
For Each box As TextBox In Me.Controls
If box.Text = "7777" Then
box.Text = "Found"

How do I read to or populate the Textboxes using StreamReader or StringReader or other means?
Basically, for my first VB project, I am creating a virtual keyboard where a sound is played from the resources on KeyDown. So far, the program seems to work except for the fact that each key needs to be clicked by the mouse before the sound is played by pressing each key (hence put the object in focus), where I need the key to play the sound without clicking the keyboard key (put the object in focus on KeyDown). Below is an example of my code:
Private Sub C_KeyDown(ByVal sender As System.Object, ByVal e As PreviewKeyDownEventArgs) Handles C.PreviewKeyDown ' C is the label attached to the first 'Rectangle' (Key)
If (e.KeyCode = Keys.A) Then 'The A key should activate the C key on the keyboard
[code]....
I have KeyPreview set to 'True' under the form's properties.
Ok here's my dilemma. here's this code I have:
If e.KeyCode = Keys.A Then
TextBox1.AppendText("C, ")
PictureBox2.Visible = True
[code].....
this code works
Private Sub TxtLname_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TxtLname.KeyDown
If e.KeyCode = Keys.Enter Then
If IsNumeric(TxtLname.Text) Then[code]....
when I replace the keys.enter with "keys.tab" it won't work..
Private Sub TxtLname_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TxtLname.KeyDown
If e.KeyCode = Keys.tab Then
If IsNumeric(TxtLname.Text) Then[code].....
I'm building a slot machine, and I'm having some trouble.re's the

When I debug and click space down, my picture box of the knob slides on down to 175, pauses, and shoots back up. The problem I'm running into, is that it doesn't do anything if I try to pull the knob down again. It doesn't bug out or anything, but it just doesn't do it again
my child form is a game that allows user to move using keydown event (arrow key left and right). But when i import it to MDI, keydown event doesn't work anymore. Am i missing something here?
