Control Arrays - Fill Array With A Loop
Jun 17, 2009
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 have a series of checkboxes named cbS1 through cbS20 and I set 'Count' as an integer.What I need help doing is taking the value of count and check the checkboxes that are greater than the count.example: count = 7 so checkboxes 8-20 would be checked.Im not sure how to make an array out of the checkboxes to use in a loop.

I am using a select case loop to perform different tasks, one of the tasks the loop is doing is putting 1d arrays together into 3d arrays. But, when i come to print the 3d array only the 3rd "line" in the array is complete. Is there a way to pass variables created in a select case out of the select case?
Here is some code to try and explain better:
Select Case Int()
Case Is = 13

I have a datagridview with 3 columns.
Now I need to fill the datagridview's datasource with 3 arrays.
Example:
(column1) Username- Joe - Mark - Thomas
(column2) Password - Joe - Mark - Thomas
(column3) Activiated - Yes - No - Yes
Then after i split what should I do? Should I add 3 arraylists in a class or should I use structure and how?

I guess I'm the newbie. I've just started trying to learn Visual basic 2008 express edition. I'm an old cobol mainframer and I'm having a hard time understanding this language. My project is to read a log file looking for claim numbers and I need to check that each claim has a start record and an end record. I need to fill up a dynamic array because I don't know how many claims there will be. The array needs to hold a unique claim#, a start claim flag, an end claim flag.

I'm new to this, so sorry if my question has been asked before. I have searched but have not been able to find, or perhaps recognise, an answer. I am using visual studio 2008 and creating an app in vb.net.

I am using a SQL query to fill a datatable from 2 associated tables. The first table has Products and the second has associated addonpackages. When I loop through my Products I am able to get all of the addonpackages for the first product but after that the datatable is only getting populated with the last addonpackage for each product. ie:
product 1 - all 6 packages are added tp the datatable
product 2 - only package 6 is added to the datatable
product 3 - only package 6 is added to the datatable
...and so on
My query follows. Why I am getting all of the info for the first product but just the last item for all others. No matter which product I would query first, I get all of the associated data with it but only the last for all others.
SELECT Products.ProductNumber, Products.Name, Products.Mnemonic, AddOnPackages.PackageNumber,
AddOnPackages.Name AS PackName, AddOnPackages.Mnemonic AS PackMnem
FROM AddOnPackages RIGHT OUTER JOIN
Products ON AddOnPackages.ProductNumber = Products.ProductNumber
WHERE (Products.Name = @ProdName)
ORDER BY Products.ProductNumber, AddOnPackages.PackageNumber

Attached is a visual representation of My Array that was used in my VB6 program the dimensions are:
CODE:
I am using an ACCESS DataBase to populate the array.
Using the For Next Loop I can access any position within the array such as a individual cell or group of cells. Also using the Step Keyword of the For next loop I can select a group of cells to manipulate based on the Step factor. This worked well for me in VB 6. I am now migrating to vb 2010 and cannot fine documentation as to how this would be done on zero based arrays in Vb 2010.
In VB 2010 I see no reference to the Step Keyword nor examples of how it would be used with zero based Arrays.
A example of my use of the step keyword is:
CODE:
Any of the above loop setups works for me using VB6 Any Documentation or code would be use in my vb6 to vb2010 migration?

I have an Access 07 database I'm using to store my data. I have no problem at all filling a worksheet in excel or a table in word from the textboxes currently on the screen and saving it as a pdf. That's basically how I'm reporting my data from my program.
Where I'm stuck is how can I do the same process for each row in my dataset that has a date or value similar to a filter? I can filter the dataset by adding a query in the dataset designer so it only displays the rows I want to build form reports for, but I don't know how to code a loop to make it work for each row.
Basically I'm looking to find a way to print and/or create pdf form from one button click for multiple records and not just the one currently bound on the screen.

I am making this program that has a loop that goes to a website and fills in a form within the loop. But first, here is my code thus far
Dim message As String = TextBox3.Text
Dim loopnumber As Integer = TextBox4.Text 'makes the necessary variables
Dim browser As New WebBrowser
Dim url As String
[Code] .....
But what happens is that the loop runs a few times then it errors on the setattribute line (line 19 above) with
NullRefrenceException was unhandled
And I have a feeling that it is not loading the page fully before it tries to fill in the form.

I have a sub that i wrote only to temporarily fill the database in during run time to be able to test a few other functions that i wrote as well ... weird thing is by the way i wrote it it should only look 100 times... but by the unique ID in the database and the information it pulls back into my list box it loops 700 times before actually stopping the loop ...
Public Sub Fill_LeftOvers()
Dim x As Integer = 0
conn.Open()
[CODE]...
Now i used step debugging and sure enough it only loops 100 times during stepping but in the database it looped like crazy ... i have also tried while x < 100 instead of the do loop but it did the same thing ... i know this may be considered a double post i mistakenly posted originally in the PHP forums earlier today ...

I am wondering if anyone has any idea how to make the controls stack and fill up the available space left by a control if the control is hidden or removed from the UltraGridBagLayoutPanel.
Example:
[Textbox 1]
[Textbox 2]
[Textbox 3]
[Textbox 4]
[Textbox 5]
If I hide [Textbox 3] as of now, it will disperse the space left equally and pad the remaining text boxes with the space. However, I would like it to do this...
[Textbox 1]
[Textbox 2]
[Textbox 4]
[Textbox 5]
Where all the text boxes will move up and [Textbox 4] will completely consume the space left by [Textbox 3].

I've got Visual Studio 2010 and I am looking to clean up my code technique, since I've taught myself and now I'm taking classes.
I'm trying to use a For...Next Loop so that I can fill a text box with sequential numbers. For some reason, all I can get in the text box is the last number and I feel that at this point I'm probably overthinking it...
All I want is on the button push the text box shows:
Here's what I have:
CODE:
Once I grasp this simple concept, I can move on to the actual challenge ahead of me, but I really want to know the proper way to handle this with out going all spaghetti code.
