I want to write a program to do Markov chain, but my states are quite large. First of all I calculate all the transition probabilities and revenues for all states(1381860 total states), and store in a multidimensional array. Public RevArr(0 To 9, 0 To 750, 0 To 282) As Long
After that the iteration of markov chain should use these as inputs to calculate the steady-state probabilities. But when I try to run the main code I got this error.Exception of type 'System.OutOfMemoryException' was thrown.
The following is the declaration of second array I add just another dimension for storing all the iterations, but I get this error. Dim stateprob(IT + 1, 0 To 9, 0 To 750, 0 To 282) As single

I am using Visual Studio 2010. I have a Splash Screen which starts first (Everything is running smoothly there). Then it Opens Dialog1. My user is required to check 5 boxes (2,3,4,5,6) (1 has been deleted). I used this Code :
If
CheckBox2.Checked
And
CheckBox3.Checked And

I've been experimenting for an 1 hour. The code didn't show errors. I tested it and it didn't work. Then I found out that I was working on Dialog 2 in Dialog 1 code. So I tried another thing and that didn't work because I can't put Dialog2 code in Dialog1 code.
I have two machines, on the first of which I have developed my application to a point of satisfactory stability. Now I want to move everything to my second machine.Both computers have the same level of XP and NET Framework code, and both have Visual Studio 2010 at the same level.I copied my application's project folder onto the second machine, but the second machine's VS 10 can't load the project because it can't find a couple of Interop files (e.g., AxMSComCtl2). All of files are present in the project folder and also in its.bin subfolder. The only observable difference between the two machines is the presence, on the first machine, of some Assemblies stored under my user name there. Copying the Assemblies to the second machine didn't help (I hadn't thought it would).Is my application permanently "imprinted" on my first computer, or is there a simple way of resusitating its clone?

View 3 RepliesI always get an exception when I try to switch between different forms in my program. Here is the exception message:
Control.Invoke must be used to interact with controls created on a separate thread
I have attached the forms to very nice variables and this problem occurs when I try to use command like MyForm.Show().
It does not happen when the forms are not attached to variables, but then I have collosal problems with refreshing the textboxes and stuff.
edit;
I have 4 different forms. When I load the main module and main form, in the Sub (...) Handles MyBase.Load I execute the following code:
In module:
Public StartupForm As frmStartup
Public RegularForm As frmRegularUse
Public LoginForm As frmLogin
[Code]....
This is the aproach I worked out to get the full control over refreshing the forms. It is a program for Motorola Scanner with Windows CE. Now, for example, when I enter the correct password in LoginForm, I want to switch to the RegularForm. When I try to use RegularForm.Show() or RegularForm.ShowDialog or RegularForm.BringToFront(), I get an exception. When I try to call the form with the frmRegularUse.Show() I can call the form, but it is being created in a different thread, I believe, so I loose control over it (when I try to put something from the keyboard, there is no response).
I'm creating a wizard kind of Windows Application. I've to show up the next window on click on "Next >" of every window.
FYI, I cannot use MDI architecture.
What is the best way to achive that?
Right now, I've put the following code on Next Click of every Window.
FormNext.Show()
Me.Hide()

VB.NET is good for me, because it is simple and its not complicated and you don't need to be so strict with syntax. I want to switch to C# but I just don't feel up to it because of the syntax and C# being so strict. What are some good reasons to switch to C# and what will make the transition easier?
View 7 RepliesI have a .NET application that was written in C# and VB.NET using WinForms. We want to slowly migrate this to something new, in many iterations. The new code will be entirely C# and WPF. We would like to utilize Prism.
As far as I know, we can't integrate the old WinForm app in Prism.
I am considering making my old app show the new app in certain instances. For example, when you press a tab in the old app, the new app opens on top of the old app, with the same tabs. Over time, only the new app would be necessary.

How to switch between form in runtime

View 2 RepliesIn my program I want to have two different 'modes', each has its own form. My main form in the program is 'Normal Mode', but there is also a mode called 'Basic Mode' which has a smaller form. How can I switch between the two forms (using buttons) by closing the other without my program closing on me?
View 6 RepliesHow can I monitor how many times a switch open and close? I am planning to add a label13 to my form and use the LPT port so every time the switch goes high (1) it will add 1 to my label13.text. The Printer Adaptor address in the target PC is 0x378. using pin 10 (ACK) or pin 2 (D0).

View 3 RepliesI want to have a DataGridView that has two columns.The first column will always be of type DataGridViewComboBoxColumn. Based on the selection in that column, I'd like to be able to change the corresponding cell in the second column to either a DataGridViewComboBoxCell or a DataGridViewTextBoxCell.I'm thinking I just need to make the second column of type DataGridViewColumn, but don't understand the mechanics of how to change the cell type on the fly.I'm working with VB.NET in Visual Studio 2005.
Update: One way around it, I suppose, is to make the second column as a DataGridViewComboBoxColumn, and change the attributes of the cell so that it either behaves like a drop-down list, or as an (editable) drop-down with no elements. The latter looks enough like a text box that I could live with it, and it wouldn't involve changing the type of the cell.
Is there a way to change the language of an ASP.NET project from Visual Basic to C# easily? I would even be willing to re-write the code as it's still fairly simple at this point.

I have been learning VB.NET since the summer and I was wondering if it makes sense for me to skip learning the things in VB.NET that I do not know and move on to C#.
I think I may be more comfy in C# because I have been using Actionscript 3 for over two years and have toyed with Java and C.
On the other hand, I've never done anything serious with C or Java.
So, finish VB.NET or learn C#?

View 7 Repliesvbc.exe has something called /optimize switch right. If I enable that what are the optimizations the compiler can do for me? The MSDN documentation just curtly says 'does various compiler optimizations'. Where can I find the complete quantified view of the different optimizations that actually goes into.Here is the thing I am pursuing this route. One of the code blocks in a module I am leading has a lot of delimited array manipulations. I believe this is going to be a heck costly in terms of string memory handling. I am looking to see if I can retire them by way of simple properties or methods so that the compiler can internally do something like our c++ inline functions making a best win-win offer in terms of both memory and processing time. I admit when the compiler translates them as inline function, the JITed code might be big in size right?
