My problem is after I created 5 rows of text boxes, I want to add random numbers to all of the text boxes in one time when I click the button.Here are my coding to create text box dynamically:
Private Sub btnAdd5Row_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAddFiveRow.Click
For Me.count = count To 5
[code]....
So as the name states; I am a newer coder.
This is the code i have:
Public Sub RandomNumbers()
Dim s(4) As String
Dim RandomNumber As Byte
I don't know if you can tell what I am trying to do here, so I will try to explain. I what to create for random numbers and place them into for different text boxes. I also would like to do this with combo boxes and their selected indexes. So if the combo box has 10 items in it; the new selected index would be the random number generated above.
I am using VB.NET vb 2008 . I am trying to create text boxes dynammically and remove them here is the code i have written so far
Private Sub setTextBox()
Dim num As Integer
Dim pos As Integer
[Code]....
I am able to create the textboxes but only a few of them are removed. by using For Each ctrl In Panel1.Controls it doesn't retrieve all the controls and some ae duplicated as well.
I have a number of images that I want to select a random number of and populate that number of picture boxes either dynamically or that already exist but can't think of the logic that would do it.
I considered dynamically creating them but don't know of a way to name them uniquely. I tried using pcbx& a variable but it didn't like that. Placing the image inside picture boxes that already exist, I couldn't think of a way to differentiate between them without what seemed excessive repetitive coding.
I am trying to follow the book 'Sams teach yourself VB 2008'. It was going well until the end of hour 4. For exercise 1 I have created the form with a button and two text boxes, but cannot work out the code I need to move text between the two boxes. The Object Browser does not seem to help - am I reading it wrong?
View 14 Repliesi wanted to create a random number generator that iterates through a series of number between an upper and lower bound. say between 1 and 100. Basically I want the number generator to pick the numbers randomly and then display them until all 100 numbers are picked without any duplicates. so thats easy I can code that. But what I don't know is how to show those numbers in the order they are generated on a windows form. So i have basically a variable that I will let be changed 100 times (or however many times I want, I don't want their to be a size constraint just using 100 as an example) and each time the number is generated I want it displayed on screen (in a list or something not sure what. Hopefully some type of scrollable list) and each successive number also to be displayed in same format beneath it so that I can see the list in its entirety. What type of form control do i use for that? I could do messagebox.show for each iteration but then user is required to hit ok after each iteration and that would obviously be a bad idea if user selected a large number to work through. Anyways, code isn't exactly necessary just point me in the right direction, i.e.what control (if any) to use.how to format the change in data?

ive got code like the code below that creates textboxes dynamically. I want to be able to click a button and delete all of these textboxes i make, however im not sure how to do this. When i tell the program to remove the TBIndex control it does not do anything. The only way i get it to work is if i put the command in the same sub as this code. This code runs in a loop by the way.
So if the loop runs one time and creates the TBIndex control and i have a line of code right after to remove the textbox, then it does not show up on my form. But if i put the command in to remove the textboxes somewhere else and run the code the loop runs abunch of times and creates all teh textboxes and the loop is complete, then the remove control part is called and nothing happens. I just need a way to clear all the textboxes off my form with like a button. I also tried painting over the textboxes with a big grey rectangle but that dindt work.
TBIndex.Width = 54
TBIndex.Height = 20
TBIndex.Visible = True

I find myself copying single files to multiple different machines, so would like to create something to help.I would like a numericupdown, which dynamically adds text boxes (which will be destination file paths). I will obviously need it to remove them too when I decrease the number.

I have created a basic query generator which allows a user to select the Select, WHERE and criteria attributes using a number of checkboxes.However i have got stuck. In the results form i have the following code
Private Sub DisplayRecord()
RichTextBox1.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(0)
RichTextBox2.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(1)
RichTextBox3.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(2)
[code]....
The program keeps on crashing if the user does not select the corresponding amount of display records from above for the amount of attributes they want for the SELECT part of the query in the intreface in form 1.
How would i go about making something where the number of SELECT attributes selected which are listed in a string create the correct number of textbox fields in the results form (form2)

I have a form which contains a large number of textboxes covering numerous panels/tab controls and I would like to have the user only have one text box visible at a given time and when the user clicks on the screen to another label with a corresponding text box I would like that to appear and the other currently open to disappear. Currently I have the following loop that goes through and changes the visibility of the appropriate controls unless it is the name of the control I am looking for:
'This is used to iterate through all the controls in the form and ensure the visibility of all other controls
' than the active control is set to false.

View 3 RepliesI've read numerous posts and threads about random number generation, but I havent' run across this.If I generate a bunch of random numbers, the results are radically different if I create a new Random generator for each number than if I use on Random generator for all the numbers. The results are much more consistent and evenly distributed if I use the same Random generator.I would have thought the opposite,because creating a new Random generator each time should reduce the number of random repetitions, if a different time slice is used to create the random number.[code]......
