VS 2010 - Making Arrays Into Panel Or DataGridView
Mar 15, 2012
I am making a array (unknown value) into a grid for a game of pairs (where you must get both of the cards). So far I have specified the array to a specific size of either 6, 6 10,10 or 16, 16. using a button. The selection is defined from the button as specified before
Dim NumberOfCards(Selection) As Integer
Dim NumberOfCards(Selection) As Integer
Now I have a panel box which I want to add the number of rows / columns as the array sizes which I cannot do. But also add a image specific to all of them.

I have an application that has a grid of rich text boxes on a panel. I would like to access and modify the text in the various rich text boxes during run time. I know this has been brought up a bazillon times over the years, but I would have done this as a series of control arrays in VB 6. Below is a simplified representation of how the textboxes would appear in a panel if control arrays were availble:
rtbA(1) rtbB(1) rtbC(1)
rtbA(2) rtbB(2) rtbC(2)
rtbA(3) rtbB(3) rtbC(3)
I find that I can access the properties of the rich text boxes via panel1.controls.item(x).text, for example, where x is the control index assigned by the panel when I dropped the controls on it.
Since I created the rich text boxes at design time and dropped them on the panel, it has arbitrarily assigned the index values, and they are not in the index order that I would desire.
How does one re-assign a control's index at design time for a controls collection on a panel? And if one has 24 text boxes on one panel, is there a way to break them into subgroups, such as rtbA(), rtbB(), rtbC() with their own index values?

not to use ArrayList for making my arrays in VB.NET. I would like to hear opinions about that, why shouldn't I? What is the best method for creating and manipulating array contents, dimensions etc?

I am using vb.net by the way. From what I understand, Xna is not usable in visual Basic. Therefore, in order to create my characters, I defined a sprite class. Now my question is.... (I am drawing everything using a timer on the form btw by the process of invalidation.)... how do I use time to cycle through the images in an image array while the instance has no focus, and whilst the class inherits the "Control" class? Basically, how do i get these instances to act without user input? I want a character to eventually respond to user input, but I also need npcs that do not need any input in order to move themselves. Also, I need this in such a way that each instance's processes do NOT interfere with the processes of others. So that whatever timing I use does not also stall the whole window/form.

I would like to add an effect where a panel sweeps out of the way to make room for another panel. This is sort of like a sliding effect, and I think at one point in time this could be seen on Apple's website under their product pages. I came up with some code, but it isn't working.

I have looked around quite a bit, and nothing seems to answer my question in particular. I have DataGridView in which I add rows and columns dependent on a certain record count of geospatial data that is held in ArcGIS. The data is then passed through to the gridview for editing. So I do not use any databinding methods, rather it is a very manual process. I store data into a two-dimensional arrays, which indexes are based off of those certain data record counts. After the loops are complete, the data should be stored in each cell dependent on index. The very last row that was populated is populated perfectly, yet the other 72 (or so) rows are blank. Here is the code as follows:

I have an unbound datagridview, the datagridviews columns count may very depending on how many are needed like so
For i = 1 To myColumn
Dim RP As DataGridViewColumn = New DataGridViewCheckBoxColumn
RP.AutoSizeMode = DataGridViewAutoSizeColumnMode.None
[Code]...
The problem with this is that it puts everything in the first column instead of each column.
What I was trying was to have it place each value into its own column.

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'm trying to add a DataGridView to a Split Container Panel. I am able to add the control, but it just places it on top of the old one.
What I want is to add it below the existing one.

I have a DataGridView control in a form, and as of a day ago, when I click on the control, I get *no* properties listed in the Properties pane of the IDE. The properties pane is totally blank. Neither properties nor events are visible. I have tried everything. Prior to this, the properties and events displayed normally.Other controls' properties are displayed when I click on them, but not the DataGridView control. If, after clicking on my DataGridView control, I use the combo-box on the Properties pane to look at any other control's properties, they come right up. If I then select my control's name (DataGridView1) in the Properties pane combo-box, the IDE crashes completely and I have to restart.

Im having a problem with a datagridview which is saved on a UserControl which is then loaded into a SplitContainer. The problem is that the forms load fine but the datagridview doesn't populate on load. It will populate however when I search for results using the toolstrip.

I have the following code, which reads data from xml file and displays it in the datagridview. It all works fine:
[Code]...
Instead of showing read data in datagridview, i'd want to read the data from xml file into one dimensional array: X(Impedances) Or is there a way to read value from this datatable into string variable without getting data from datagridview? The point is: i'd want to scan through all "Impedance" values (which are read from xml file) and compare with value y to catch the nearest value to y. How to do that?

While dragging a table which has a primary key from the dataset in my project onto a form to create a datagridview I get an error. The tableadapter for the table has an Update command in it. This is the error:
An error occurred while performing the drop:Code generation for property 'UpdateOrder' failed.Error was: 'Type'Action.Action2DataSet TableAdapters.TableAdapterManager +UpdateOrderOption' is not available in the target framework.'
Given that the tableadapter has an update command in it (which I did not change) .

does your IDE ever get amnesia?in the line before it is clearly defined.in the following line it is not.Maybe it's a faulty translation from Tangible Software.the C example i'm looking at:
IAnimatedMeshSceneNode* newNode = (IAnimatedMeshSceneNode*) oldNode->clone();
translated as:
Dim newNode As IAnimatedMeshSceneNode = CType(oldNode.clone(), IAnimatedMeshSceneNode)
had to make a dummy for it because i can't use arrays with CType.

I need to load a CSV file into a set of arrays, and show the output into a listbox, which are associated with other textboxes(labels). earlier i had the names all loading into the listbox, but the values in the label were only correct for the last line in the csv file, not corresponding correctly to the listbox values.
Here's my current
Option Explicit On
Option Strict On
Imports System.IO
Public Class frmMain
Private Sub frmMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

And here are the contents of my csv file:

I want to put the matches from a regular expression into an array or something that i can use to compare it with another array, it being the lines from a txt file names "users.txt". Code A:
[Code]...
And the second code will do the exact same thing. What i want to do is compare each line in the Txt file (Code B) to the reg expression matches (Code A) and for it to alert me if any is missing. So it needs to compare Code B to Code A. (PS. Order is irrelevant, it can be in different places as long as its there) In my other thread i got a little confused and couldn't clearly communicate what i was trying to do.

In VB6 I load a recordset containg all of the records (6 fields per record)in a table into an XArray and then manipulate the records in the array and then write them back to the original table. The array issorted by the first field (1 to maybe 8000 or more) I need to find records in the array by an ID field and then move them (because of some external criteria that happens many times) from say number 400 to number 375. Then all of the other records between 375 and 399 were renumbered up 1 to fill the gaps left by the move.
The XArray worked well as it could find and also move to a next record easily to facilitate the revisions to each record quickly. Everything is done in VB6 in code and nothing visual needs to be shown to the user until say 2000 of these external changes are complete. What is the best, most efficient way to do this in the .Net framework in VB2010. Datasets, Dataviews. tableadapters, arrays. enums ?

I have a DataGridView object to which I've bound a list of objects (of type Asset) returned from a database query.I'm programming in VB using Visual Studio 2005.I want to grab two copies of the bound object (calling them oldAsset and newAsset) from the selected row in the DataGridView, update newAsset based on input from other controls on the form, and pass both oldAsset and newAsset to a function that will update the appropriate record in the DB.I try to grab the two copies like this:
Dim currentRow As DataGridViewRow = Me.AssetDataGridView.CurrentRow
Dim newAsset As Asset
newAsset = currentRow.DataBoundItem
[code]....
Opening a watch window on oldAsset and newAsset indicates that the appropriate values are pulled at this point. But when I try to change a property of just newAsset, like
newAsset.CurrentLocationID = cboLocations.SelectedValue
I see that the corresponding value in oldAsset is also changed. This is not what I want, but it's obviously what I'm telling the computer to do.

I have a VB.net console app and I am opening a function in a dll written in fortran. I am passing 3 arrays through the function by reference. When they come back out the otherside they ahve all tunred to arrays of only one element And that element is 0.I read on the internet somewhere that when doing this kind of thing it is a good idea to only pass the first element of the array into the function.I tried changing my function declaration to accepting single elements rather than single dimensional arrays, and now the arrays are the same length before and after the function call, but they don't seem to be changing at all, so i'm not sure that this is working

I am moving a project from 2005 to 2010 and I wanted to make some changes. Currently I have a customer form that has a 3rd party tab control in it. A few of the tabs are Customer Information, Invoices, Orders, Quotes. Each tab has a ton of controls and the form has a ton of code. What I would like to do is have individual forms that show up on each tab. So, I would have a Customer Form, Invoice Form, Order Form, and Quote Form. This way I can also use each from individually as I have the need to. Can this be done though inheritance or something like that?

I just started using Visual Basic and I'm trying to make a mapping application.
Background: I'm basically trying to make something similar, but on a very small scale, to Google Maps. A user loads an image in to an picture box which is put inside a panel(so i can scroll the image). When the user has uploaded an image(a map) i want to allow him to add Labels on where he clicks. I've already done this part except the i get the wrong coordinates when i scroll through the rest of the image. If i don't scroll, the labels get placed spot-on.
I use e.X and e.Y on an event of a mousedown on the picture box. I get the correct coordinates in relation to the picture box. But when i use these coordinates to create the labels after i have scrolled, it places them in the wrong spots. I dont know how to compensate for the scrolling.
