Basically I'm trying to make a picturebox array so to speak and at the momment I'm currently linking each picturebox one by one with the corresponding array row/column. Seen below.
board(1, 1) = Me.Picturebox1
board(1, 2) = Me.Picturebox2
board(1, 3) = Me.Picturebox3
board(1, 4) = Me.Picturebox4

I have a 2d array of data that I have performed the sum of the individual column of the 2d array. I want to send the results to a datagridview and also will like to have the result as a 1d or 2d array.

Array1(0, 0) = 5

I have a loaded DatagridView which contains a row/column with an employee number in it. Outside of the DatagridView at the the top of my form I have a small PictureBox. My goal is for the user to select the employees row (not cell),pull the employee number from that row/column, and then use a LINQ query against another table to display the image stored in that table.
Determine the event needed in the DatagridView?How do I pull the employee number from the selected row?What considerations, if any would the LINQ query need to pull the picture from the table?
i would like to ask if how do i create a column of picturebox.. something like a thumbnail, with a specified number of columns inside a form.. the number of picturebox depends on a variable.. has anyone done this?something likeimage1 image2 image3image4 image5 image6

I am just wondering how i can create a picturebox array like i could when i copied and pasted another picturebox in VB6 and it asked me if i want to add them to an array. Doing so made them code like this:

In the beging of the project I am entering this code.
Dim
pic0 To 30000)

Then in the project I change the images for some pic(i). So now I would like to make a click event so when they click on a pic(turebox) it will change its border. (eg
pic(current).BorderStyle = BorderStyle.FixedSingle
editing a picturebox...i have a class called panelArray and it builds an array of panels based on the number of panels i pass it...each panel has 4 labels and a picturebox added to it when the panel is created. I'm able to edit the labels by using something like:
Me.HostForm.Controls.Item(replaceIndex).Controls.Item(2).Text = ""
Since there are 5 objects total (1 picturebox & 4 labels) i thought i would be able to just use the same strategy for the picturebox, but it doesn't like using Image in the same manner it uses .Text?
I have recently decided to move on from VB6 and upgrade a program I made in it to vb.NET.
I have a form that looks like this

I am required to make a game of concentration, whereby cards are shown for x amount of seconds and then truned over. The user then needs to remember where the cards were and pick two at a time in order to win points - whilst being timed.
Any pointers on where to start, or how to make a 2D control array of pictureboxes that can display the cards into a grid of (10x10) pictureboxes randomly?
I'm filling a FlowLayoutPanel with an array picturebox that depends of the number of files in a selected folder. The problem is that images appear stretched, and I want to keep the aspect ratio. Resizeimage is the resizing rutine and works fine. The clicked image wil be shown in a picturebox with a new sise (bigger).

datagridview column to array
View 8 Replies* I posted this in VB forum at first by accident instead of .Net* I am trying to create a console application that computes the row and column sum and prints the elements with the resulting sums for each row and column.
[Code]....
My column sum code is currently showing the row sums. I need the column sums to display in descending order. So i know it would require a sorted array, but i'm not sure how to go about doing that given i can't get the correct values to show up. So I would need it to display as "Column sums are 12, 20, 13, 24, 51. " and then the next line would be "Column indexes are 1, 3, 2, 4, 5."
if you could possibly point me to the right direction, that would be great. i have tried researching about this but found no solution.i have a 2d array which holds student name and 3 grades (eng, maths, science.)student array (24,3)Now, i would like to use the data which is held within the array to create averages.I need a total class average for: maths column, eng column, and science. I also need an overall average for all subjects.the code i have used, so far, brings some odd results.
studentarray(i,1) / count
studentarray(i,2) / count
studentarray(i,3) / count

I am having some trouble with creating a simple function that converts a column of a datatable to an array (containing all numbers). Upon running it, it says "Index was outside the bounds of the array"; however, I couldn't understand why my function would create this problem.Also since I do not usually program using VB.Net, I am not sure if my function has other errors (like syntax errors).
View 2 RepliesDim array1(9,2) as String
So basically, 10 rows and 3 columns and say I want to sort them by the values in the 3rd column.
Each row is essentially a record of data and must be kept together.
Now I know that you can't use the array.sort method but would I have to use a bubble sort or something for this?
What's a good way to manipulate the records while still keeping each row linked together somehow.
[Code] This is the coding i have used to a datagrid with textbox and combobox column. But for the first column i have to generate a unique name for each item and display in the first column of the data grid. I used array of string and tried to add that array value to the first column. But it is showing the error " Object reference not set to an instance of an object". how to add the unique name column to my datagrid.

I am having issues assinging values to a multi-dimensional array.
I am trying to build a 2 col, unlimited row array and populate with data from a data reader.
Dim tblArry(,) As String = {}

While reader.Read()

When I use a Jagged Array I can get this to work. The Reader portion is workig just fine, but the coding is just not clean for this problem.
I'm working on a piece of software to read a comma separated text files with thousands of lines each line has around 32 word separated with a comma What my code does at the moment it reads the file line by line choose 11 words out of the 32 and outputs them into a new file. This is actually time consuming although i used threads and a progress bar my manager still not happy. So i was thinking if i can read the whole text file into a 2 dimensional array and then choose certain Colums to output on the new file that will make it work much faster. But i don't know how to read a whole colum from a 2 dimensional array. And let's say for example the array is gonna be like array(9500)(32) where the first argument representing the number of lines and the second represents the number of fields in each line. Is there any way to access it like this array(all lines)(15) I'm using vb.net 2008
View 2 RepliesI would like to retrieve a single column of about 800 rows in a table and save these values in an array so as to reference them later on. How can I do it? I tried:

And it didn't work. The col1 is of type Int64 and so is the array prev_ob(). Please let me know how I can save it to an array.
When you have a single dim array, you get number of items in with simple Ubound(array). What is the most efficient way, to get number of items in each "column" in 2 dimensional array? My code (part):
.NET
Public Shared LoopStock()() As LoopStockDef
Public Structure LoopStockDef
Dim EntID As Int32
Dim LoopNo As Int16
Dim LoopType As String
Dim loopStPtX As Int32
[Code] .....
You can't Ubound multidimensional array as you can do with single dimensional array, as the second dimension can have different number of items in each column (DimX in the following table)
DimX | (1) | (2) | (3) | (4) | (5) |
-----------------------------------------------
DimY | | | | | |
(1) | 45 | 41 | 15 | 48 | 49 |
(2) | 35 | 26 | 98 | 15 | 31 |
(3) | 12 | 23 | 36 | 69 | |
(4) | 88 | | 26 | 28 | |
(5) | 74 | | 89 | | |
(6) | 36 | | 25 | | |
If you do
.NET
UBound(LoopStock, 2)
You get size of 2nd dimension, not number of items in the table for particular column. The best solution which comes to my mind is to define another array, a multidimensional counter, like
.NET
LoopStockDims() As Int16
And count every added item for each column. Is this the best way?
