In WPF, I have a Uniform Grid and would like to be able to find the row and column based on the index of a child element.
I know there is a mathematical way of doing this and would rather not use a normal Grid.
If it helps, I can get the total number of rows and columns by using:
Math.Sqrt([*uniformgrid*].Children.Count)
i am having trouble putting a value in a textbox. Each time a ticket is sold i put the total price in a textbox, each time a ticket is sold for the same concert it increases by adding its self to the total price. It works at the first sale, but after that it breaks down. here is the code
Private Function DisplayMoneyTaken() As Integer
Dim totalMoney As Integer

I am trying to find a record within a nested Dictionary, so that I can add more records to the sub-Dictionary.
The intention is to be a dynamic configuration, where no matter what I pass into it will group into like item categories that have already been added. If there are no like items it will add a new category.

I have a text file that is automatically generated by an older computer system daily. Unfortunately, the columns in this file are not delimited and they are not exactly fixed width (each day the width of each column could change depending on the amount of chars of the data in each column). The file does have column headings, so I want to find the width of each column using the column headings. Here is an example of the column heading row:
JOB_NO[variable amount of white space chars]FILE_NAME[variable amount of ws chars]PROJECT_CODE[variable amount of ws chars][carriage return]
What I want to do is get the index of of the first char in a column and the index of the last white space of a column (from the column heading). I would want to get the index of the "J" in JOB_NUM and the last white space before the "F" in FILE_NAME for the first column.I guess I should also mention that the columns may not always be in the same order from day to day but they will have the same header names. I know I can use the string.indexOf("JOB_NO") to get the index of the start of the column, but how do I get the index of the last white space in each column? (or last whitespace before the next first non-whitespace that denotes the start of the next column)
How can i get the Column Index and the Row Index when I click on the ListView?The ListView1.FocusedItem.GetSubItemAt(e.X, e.Y).Text function only gets the text of the first column, I can't find the option of getting the Index of the Column and Row upon clicking.

View 2 RepliesI'm an intermediate student taking on a monopoly game for a summative project. I decided to simulate the game monopoly. The rules are the same as the board game, so the idea is that each "property" or board piece is a button. I will have variables for the players position and player totals. To indicate an owned property, I'll change the buttons to flatstyle and use the bordercolor property.
To indicate the player position, I change the text on the button to include "Player: " etc. The trouble I'm having is that each button is named based on position, followed by the name. ie: "btn1Start", "btn2BalticAvenue", so on and so forth. Now, once I roll the two die and gather random integers, I add the total to the player position. Now what I want to do is find the button that the position corresponds to.
Private Sub turn(ByRef playerPosition As Integer)
Dim die1 As Integer = Int(6 * Rnd() + 1)
Dim die2 As Integer = Int(6 * Rnd() + 1)
playerPosition += die1 + die2
Dim button1 As Button = ?
I've tried various methods. Me.Controls.Contains("btn" & Position) is a boolean, so I can't make an object control class equal to that. Me.Controls.Find requires an exact name, so I can't do Me.Controls.Find("btn" & Position) because it needs the full name - each property has something else added on to the name (eg "BalticAvenue"). I want to set the button equal to the specific button based on the turn position, so I can update the text to include the player and allow him/her to initiate the property's effect (buy/pay rent/or chance cards).

First of all, I'm a somewhat-experienced VB3 Developer, and I'm trying to convert a VB3 app to VB.NET.I got the programming guide (http:url....) by searching the web.The problem I'm having is the syntax for .NET is way different than VB3, and that's OK, but finding the correct syntax is very difficult.I'm trying to eliminate duplicates in a ListBox:
When I access the Programing guide, I see that:
ListBox.SelectedIndex Property
Gets or sets the zero-based index of the currently selected item in a ListBox.I also have Murach's and Stephen's manuals, and they say the same thing.Visual Studio converted The old .ListIndex to a VB6 Function:
If VB6.GetItemString(PlayList_ListBox, I) = VB6.GetItemString(PlayList_ListBox, I + 1) Then
This is Try #1. It generates: VB6 is not declared. It may be inaccessible due to its protection level.Then I read that VB6 is only for converting old code.So then I tried SelectedIndex:

I've tried to use the DMAX Function in my VB windows application to find the highest value in a column in one of my tables, however it doesn't seem to work. After doing some research, I think that the function is only relevant to VBA, although I could be wrong.

'Dim HCCNUM As Int32
'HCCNUM = DMAX("[HCCID]", "tblHCC")
How to find the maximum value in a column in one of the tables in my database?
