ames tile1 to tile 100Array is loaded from a textfile of 10,10 (not stored as a 10,10 just parsed from line to line, which I feel needs to be changed asap)Each tile is then given a corresponding graphic (e.g. grass, water, lava) and soon hopefully I will add interaction with certain tiles

In my application i need to move rows and columns in tablelayout panel at runtime.like how to we are doing at designtime.
View 3 RepliesSo I am writing a program that uses ArrayA(10) and ArrayB(10) and uses Do loops to output the sum of ArrayA(1) + ArrayB(1) in one column then the difference in the next column, then the product in the next column, then the quotient in column 4 of a Matrix(10, 4) in a listbox. And continues doing this until there are 10 rows of 4 columns. I was wondering for tips on how I can get this done.
View 6 RepliesI have Dataset ds filled up with values Until now I was displaying values in GridView. Now I want that all the rows should be columns and columns should be rows.I have 2 options: Either 1 I can directly convert grid to columns and display it, or 2 I can convert the GridView to html and then write loops to convert. I was trying the 2nd option but I cant figure out how I should do that.[code]With this code I am still getting same as GridView. Please help me for converting rows to columns and vice versa.
View 1 RepliesAt design time in the IDE, you can ctrl-click or drag a box around multiple controls on a form and move them all at once. How do you do that at runtime. I need to be able to create image maps based on textual copies of medical claim forms that are generated from different systems and the ability to create dynamic label controls and move a single or multiple controls and resize is required. How does MS do this in the IDE?

View 1 Replieshow i can get the grid to select a row by clicking on any cell in the row?
The only way i can do this at the moment is by setting the AutoGenerateSelectButton property to True, but this adds a column to the grid with a crude "select" hyperlink and only selects the row if the word "Select" is cliked on.
Whenever a row is selected in my GridView, I want to take the ID field of my gridview's dataset and form a unique URL with it (use a ?id=1234 parameter). In the Page_Load event I have the following code:
TextBox1.Text = Request.Url.AbsoluteUri.ToString & "?id=" & _
GridView1.SelectedIndex.ToString & Environment.NewLine
I have a DataTable with about 64 columns, including "UserAnswer", "CorrectAnswer", and "QID_Lookup". I am building a LINQ that will select all the rows that have a correct answer (user answer matches correct answer), but I only want to select rows that have distinct "QID_Lookup".
[Code]...
The problem is that the result set includes duplicate QID_Lookup values. How can I include only distinct QID_Lookup values? keep in mind that there are 64 columns, so if I can avoid it, I wouldn't want to list each column individually for selection.
I have created a bound DataGridView and then added an unbound checkbox (name=select) for selecting multiple rows. The problem I'm having is the row doesn't actually get selected when I set .selected to true which I'm doing in the CellValueChanged event. When I trace it the code is properly executed but the row is not highlighted when the checkbox is checked and consequently not selected in the grid.There is no mouse or keyboard and the input device is a USB button panel which we built.

I am stuck on how I go about using the nested for loops.Add code in the Draw button�s Click event to create the number of rows and columns selected, using the character selected Use nested For loops to create the rectangle of characters based on the user selections. The outer loop will control the number of rows. Use the value selected in the Rows combo to determine the stopping value of the outer loop. Use the value selected in the Columns combo to determine the stopping value of the inner loop, which controls the number of characters per line.
