Loop Through Child - Bind Textbox To Field Of Parent Table

Mar 22, 2010

First I have 2 tables, for example Customer and Orders, and in the database there is a foreign key relation between both. For clarity Orders have a foreign key field to the primary key of Customers, thus Customer is the parent and Orders is the child table of the relation. My application is a Windows Form application, and I add a dataset to the project, in which I drop the 2 tables, and the relations between the 2 tables is automatic added. Now I will om a form loop through the Orders table (witch is the Child table) and show in a textbox some fields of the Orders table and also the Name field of the related record of the customers table. Regarding binding a textbox fo a Orders field I do it this way,

Dim myDs As New DataSet1
Dim myAdpCustomer As New DataSet1TableAdapters.CustomerTableAdapter
Dim myAdpOrders As New DataSet1TableAdapters.OrdersTableAdapter
myAdpCustomer.Fill(myDs.Customers)
myAdpOrders.Fill(myDs.Orders)
Dim myBindingSource As New BindingSource
myBindingSource.DataSource = myDs.Orders
myBindingNavigator.BindingSource = myBindingSource
TextBox1.DataBindings.Add("Text", myBindingSource, myDs.Orders.OrderIDColumn.ColumnName)

But now I can't find how to bind a textbox to a field of the Customers table witch is the Parent table of the relation.

Loop Statement - Display A Table Giving The Balance On The Loan At The End Of Each Month

May 17, 2010

I am trying to create a program in vbfor this problem: "A TV set is purchased with a loan of $563 to be paid off with 5 monthly payments of $116. The interest rate is 1 percent month. Display a table giving the balance on the loan at the end of each month". It must have 1 button and a list box that displays successive balances, contains loops to balances, loop code includes output to the list box, List box displays 2 columns (one for month and one for amount owed) and 5 months are displayed and the amount owed for each. The Amount Owed should go down each month from month 1 to month 5 where month 5 will equal to $0.00

Here is my code so far but somehow the 1 percent interest i cannot get to add on each month so I am not getting the write answer.

Code:
Dim rate As Decimal
Dim loan As Double
Dim pay As Double

[CODE]...

I have attached a jpeg of what the end result should look like when code is being run.

Evaluates Loop Condition In Do...Loop Statment To Determine Whether Loop Instructions Should Be Processed

Mar 14, 2011

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

Refresh Table Adapter When I Have A Child Table Attached With Parent Table?

Dec 21, 2011

I have a data table whose one column is related to a column of another table. I have a listbox in a form which shows a column (which is sorted by another column value by ORDER clause) of the parent table and other columns are in textboxes. The child table is represented by a datagrid. When I add a new item in parent table and click save, the newly created item is listed at the bottom of the listbox violating my ORDER clause. When I wrote some codes to fill data again after updating, it shows an error message[code]...

Dim hwnd As IntPtr
Dim prc() As Process = Process.GetProcessesByName("open")

VS 2008 - Writing To XML On Every Loop

Aug 26, 2009

I am very close to finishing this function, what I am trying to do is a for loop which:
1) Grabs the value
2) saves the value in an .xml file for later use
Currently when I use a for loop to feed in my function I overwrite the hiddenFields.xml on every pass, instead of adding to it.

Calling function:
vb.net
For X As Integer = 0 To postingHiddenFields
Dim hiddenFieldsReturned As String = functionDealWithHiddenFields(HTMLResponse, postingHiddenFields, X)
Next
[Code] .....
So basically on every pass of the function I'm overwriting the values instead of adding to them.

VS 2008 For Each Loop (Step Through / Into)

Jul 5, 2009

The following code is executed at an interval of 60000 milliseconds.

[Code]...

I tried doing a step through starting at a break point i put at the For Each line. It will go inside the For Each loop but when it reaches the first if statement and it finds that if statement false it will not go to 'Next' and continue to execute the loop instead it goes to End Sub. I want to be able to view what is going on inside the loop, i think the final upload process works so it does do the loop, though i can't step through to view it.

VS 2008 For Loop With Integers?

Jul 30, 2009

I currently have a grid of 30 buttons, (6 x 5). So I named them btn1_1 - btn6_5

When the board loads up (this is for a jeopardy game) I have this

code
For counter = 0 To 5
Btn1_#.text = counter * 200
Next

Is there ANY possible way to do that (replace # with the number of the counter.) I doubt there is, but it never hurts to ask!

As a side note, where is a good place to post the jeopardy game that I am making in these forums, i tried both the code bank and gaming forums but they are dreadfully inactive.... since it is in VB.NET, i was wondering if i could post it here.

It is still in the making, but I would really like some feedback as i worked hard on it and got stuck for 6 hours on the save/load feature that was getting messed up cuz of a difference from A and a lol.

VS 2008 How To Loop Through Controls

Aug 23, 2011

I can't use the normal method, my controls (picture boxes) names contain numbers such as 00, 01, 02 etc which corrispond to my multidimenional array.

I'm attempting change the picturebox's values in a for loop via the counter in the loop, for example:

For i = 1 To 4
PictureBox(i).enabled = False 'Picturebox1 will be the first one(counter starts at 1)
Next

I basically need to access each one as I would with an array, I can't type the full names out, can only refer to them via their names + counter number because I don't know what control name I would be dealing with at that time in the loop.
