View 4 RepliesMakes 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.

i want to loop through the form control RectangleShape but they show me a ereur when i write the type of the controle ((RectangleShape))
For Each cnt As Control In Me.Controls
If TypeOf cnt Is RectangleShape Then
End If
Next
they show me this ereeur : "type 'RectangleShape' is not defined."
it works as well whene i use the control type TextBox or any other controls in the VS FORM like this :
For Each cnt As Control In Me.Controls
If TypeOf cnt Is TextBox Then
End If
Next
What type can i assign a for loop control variable? I want the for loop to be the output file of a calculation, but i can not define it as anything, and i do not know how to write it so that the output is actually what the code spits out once the code has finished running.

I Have a VB.net form with lots of controls to save as config: textbox, radio button, check box... but these a Scatered inside tabs, panels, groups..
View 4 RepliesUsing ASP.NET and VB.NET code behind, I have the following code:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim I As Integer = 0
For I = 0 To 10
ListBox1.Items.Add(I)
ListBox1.DataBind()
System.Threading.Thread.Sleep(300)
Next
End Sub
The intended output of the code is to update the listbox1 control at each iteration, but what really happens is it updates the listbox1 control after the entire loop finishes..Is there a way to update the listbox1 control as its intended by the code logic?
I have an array of labels on my form which are all named "lblLabel1" thru "lblLabel9", but I want to be able to take a users numeric input (lets say 3), and display the 3 on lblLabel1, then I need it to increment by one all the way to lblLabel9. How can I do this? I was thinking a loop so this is what I came up with, but it didn't work:
For b As Integer = 0 To 8
lblLabel(b).Text = String.Concat(intSomething, "+", intAnother, "=")
Next
'Where b = the label number (I know it's zero based, I would change it later)
I am trying to port a program I wrote with old VB 1 and I have many control arrays in the program, and it was so easy to do this in older versions of VB, now I am trying to find how to do this and all the answers I have found are a major productions, to replace something that was so easy to do? I would think that microsoft would make programming easer with each new incarnation. instead they are making it harder. doing away with the DATA and READ statement, now it is much harder to fill an array with a loop, now you have to enter each item in an array ONE by ONE. they did away with the ON statement, I had several ON statements, I had to make complex Select case constructs. to replace a simple one word statement?
To make an array of controls in OldVB all you had to do is Name a Second control the Same as the First, and a dialog pops up and ask if you want to make an array, you click Yes, and that's it, what could be easier than this?
I am fairly new to VB but really enjoying programming. I'm looking to create a counter that counts to 25 and loops back around again with a button control and another button control to stop it. So I press a button to start and another to stop and I want it to display the number it stopped on. Is this possible? and how do I do it if it is? I can figure out how to display the label and create a simple counter(that doesn't loop), but I'm unsure on the rest.
View 2 RepliesI am trying to implement a progress bar which increments based on a For Next Loop. The idea being that the increment should occur prior to the next go around of the loop. I have a user control form called "Progress" with a progress control on it called "Bar". The Min Value will be 0, Max 20, and Increment 1.
For X = 1 to 20

I am trying to use a scrollbar to move forward and back through records in a datatable and to populat an entry in a field to indicate that individual records are selected.In short i want to represent a the sum of a specific field of those records selected. Of course being a scrollbar it has to work in reverse and unselect records when the user moves it backward.
The purpsoe of the scrollbars is that there will be five of them and they will represent years. The records on the other hand represent projects which have an output (say money saving). The idea being projects selected in year one then cant be selected in year two. I am planning to do this by assigning a value that indicates they are already allocated to the previous or other years scroll bar. I can set up a loop to go through the whole data set and do this for a year (and have), but i want to use scrollbars and make it interactive.

I am trying to build a function that returns a chart. I want to have a parameter to account for times where i may need more than one series. How does one loop through to create multiple series? I would think you would need a variable for each series. The function is below. I would think that if there were 5 series that each of the "Dataseries" variables should have their own name. Do I then refer to them by index only?

I'm trying to lern VS 2010 from VB 6 and one of the things i'm hawing a problem whid is control array.In vb 6 if you create a text box it's named "Text1" and if you yust copy it and paste it it renames to "Text1(0)" and the new one's name is "Text1(0)" and the code would lock like this
[code]...
then it would print for each loop the random result in one of the text boxes corresponding to i.
How do i do this in VS 2010?
I cant figure why the VB JIT Debugger control transfers the error to the program when I run in Debug mode and goes on in an infinited loop... I am using VB.NET 2008 and MS Access as the database backend.What I am trying to do here is that whenever I catch an exception (I have some C# code dll added to this main program and it should catch the unhandled exception and the addhandler routine will follow suit. So the moment any unhandled exception is caught MyHandler method is invoked and I need to take the backup of the database (Delete if the original file exists, copy the *.bak file as the original file name(was created during new file development) ,name it as *.mdb ) show a customized messagebox warning the user to abort (custom crash dialog instead of the standard default one)Somehow Myhandler goes in an infinite loop stop at line Globals.startBackup inside Private Sub MyHandler..Any idea on this weird AppDomain.Unhandled exception and how to prevent this from happening?

I am constructing a program, i am new to Visual Basic, but i have past programming experience.

So I made a simple patform game where the player has to jump quickly while the platforms move to the bottom of the screen, as to not touch the bottom of the screen. But, I need to know how to create a loop to loop the locations of the platform. This means that after twenty or so platforms, the same platforms come up again, so that the player will have an "endless" game.
