i know there are no "control arrays" in vb.net. i do come from vb6, and im trying my way now within bv.net, so please be gentel...
if someone could please post a simple code to do the following, it would be great:
i have 3 textboxes called txtBet1, txtBet2 and txtBet3.
i have another 3 texboxes called txtResult1, txtResult2, txtResult3.
so i want to have one loop code, to get the value in txtBet1, calculate somethings, and put it into txtResult1.text.
i know it's basic, but i tried using this sample here as a reference, but its not really understandable for me, because its not really choosing the exact control i want to address...
this is from Microsoft website - a comparison between vb6 and vb.net:
"' Visual Basic 6.0
Private Sub ClearText()
For i = 0 To Text1().UBound

On 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"
End If
Next

Trying to write my program in vb.net 2010. I have read my 2 books and have been playing with the code a bit. Got streamreader and writer and My Namespace understood as far as text files go. Now I'm trying to get all my textboxes in tabcontrol tabpage1 to be cleared of text thru the For Each loop.
I've tried various ways and keep getting invalidcastexception error. I even changed the tabcontrol and tabpage modifiers to public. That did not work either.
[CODE]:....................
I thought the code would not only clear all textboxes on tabpage1 but on all the tabpages. The help tells me that "When casting from a number, the value must be a number less than infinity and to make sure the source type is convertible to the destination type. I have three tabpages and that is definitly less than infinity. The source type and destination type puzzle me a bit.
Here is what I got using intellisense, however it not only clears the textboxes of text on tabpage1, but it clears the labels and buttons of text too so it is not a perfect solution.

I have 12 textboxes named TextBox1 to TextBox12. How can I loop through these textboxes to assign and read the values? I.e.:
Dim strTextboxName As String
For i As Integer = 1 To 12
strTextboxName = "TextBox" & i
TextBox{i}.Text = ...... ?????

I have 4 radio buttons in a group box that I populate with answers from a database.
1.) The way the program works is I first populate one of the buttons randomly with the correct answer.
2.) I then proceed to populate the remaining buttons with False answers, by starting at the first button to see if it has a value or not. If not, it is then populated, if so then its skipped and I move on to the next button. This continues until I populate the remaining three buttons with false answers.what is the best way to prevent the three false buttons from having the same value? And where can I find an example.

I'm writing a little program for class that determines what your Chinese Animal Sign is based on the birth year you input. My test expression for the structure is a boolean. If it is true, the case is entered.
The value entered must be at >= 1924. If not, the first case should display an error message. If it IS >= 1924, it passes to the next case to see if you were born under the first animal sign and so on.
I set a breakpoint to find out why it was displaying the error even though I input 1924. The boolean for "< 1924 = True" comes up false, so that case should be skipped, I thought. But the code enters that case anyway and displays the error.I'm new to case structure, but I understand if statements very well. What am I missing?

Nice simple one (I Hope) to start of the day. I have got a load of calculations going on and then a set of rules being checked after the calculations. I then have 9 booleans which check against the varibles. Basically I would like an easy way to check how many Booleans are False and how many are True.

I just been working with datetimepicker and I can't get it working if it is unchecked. When it is unchecked looks like it is not taking anything in. I can't load the value in it if it is unchecked which I need to have unchecked until the user ticks it by selecting the date.even if I am trying to trick it by doing this:
dtpCallback.Checked = True
If (Convert.IsDBNull(dsOrders.Tables(0).Rows(0)("callbackDate"))) Then
Else

I have a couple of textboxes whose databinding's text is set and also readonly is true and visible is false. but when I try to read their values they are all null unless I turn their visibilty to true. The same method is also needed to add a new row to the table (when using bindingsource1.addnew()).

I have a control which validates the data entered and it is working. I created a Close Button and set the Cause Validation property to False. The validation keeps on running even though the property is set to false. As a matter of fact, it happens to all the controls as if there is a bug in VB.Net.

I got a couple of issues with my windows application VB.Net. I seem to cannot set the form to be invisible before it shows up for a second, there is no option in the properties of a form and also if I set the form to visible = false before the form is loaded it doesn't work.
So this does not work:
Browser.Visible = False
Browser.Show()
and this does work but the form shows up for a second which I am still not very happy with
Browser.Show()
Browser.Visible = False

I have a form which won't open properly under certain circumstances if a particular Button is set to visible = false. Under the same circumstances if the Button is set to visiblbe = true the form does open properly or if the line of code at a certain place where it is set to either visible = true or visible = false is commented out or not there then the form opens properly. If any one of the 5 phases on my form are turned on then the problem doesn't ever occur but if none of the phases are on then the problem does occur. I just found a fix for the situation but I still am not clear about what exactly is going on.

I have a graphics application that uses graphics paths. Code seen below. You can use keyboard characters to display information. When a label is set to visible = false after being turned on for a number of seconds a stray image is generated. The stray images are also sometimes generated when the label is first made visible.
' points p10b, p2b etc are defined elsewhere
Dim GrpPoints As PointF() = {p10b, p2b, p3b, p11b, p5b, p6b, p12b}
GrPath = New GraphicsPath ' 7 path points
GrPath.AddBeziers(GrpPoints)
[code]....
I tried stopping the code from running when the label is set to visible = false but the stray image is still generated but just later. If you want more information let me know.The white arrows points to the stray image that is created just after a label that displayed information was set to visible = false

Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.

Option Strict On
