I'm writing a program that solves sudoku puzzles, but it keeps giving me StackOverflowException. I've tried to make it as efficient as possible, and cleaned up my code, but it still does this once it reaches a certain depth of recursion. how I can increase the stack size so that it can handle this recursion?
View 5 Replieshow can i increase the stack size on my ui thread from within my app?my app recursively draws onto a bitmap which is then displayed in a picturebox + only causes an error when i increase the size of the bitmap. i.e. the same drawing operation on a smaller bitmap works ok.

I placed a button on my form that measured 59mm in width (approx 2.25 inches for any Americans).When you run the project as you'd expect it still measures 59mm.However when I set the form as a child to my MDIParent and run the project the button now measures 67mm (well over 2.5 inches) an increase of 13.5%.Is this a bug or do I need to just change some setting somewhere?
View 6 RepliesI'm implementing multi-level undo/redo via a pair of stacks. This works well, but I'd like to limit the number of undo actions (actually objects representing the state of the application) . Once the limit of actions in the stack has been reached, I want to keep adding actions to the stack, but get rid of the oldest (bottom) items as I go.
View 3 RepliesI have a recursive function that causes a stackoverflow for big inputs. So I want to enlarge my stack. I have never worked with threads so maybe I'm doing something wrong but when I try to make a new thread, the description for the second argument (StackSize) says that if I use a stacksize bigger than the default one, this argument will be ignored and the default size will be used. How to increase the stacksize? Or how to create a thread with a bigger size than the default one?

I'm trying to read the lines of a richtextbox into a string array but no matter how hard i try i keep getting a stackoverflow exception. This is what I currently have (Notes is the name of my Richtextbox):
Dim newarr() As String = Notes.Lines Before that I tried:Dim newarr() As String = Notes.Text.Split(Environment.NewLine) And also: Dim newarr() As String = Notes.Text.Split(vbCrlf)Nothing I try is working!! Where am I going wrong??
How do i make the number in a particular column of an MS Access database to add up by 1(one) each time a button is clicked? I have tried the following code but everytime its clicked, it just seems to "replace" the 1 which is already in the database.
If CheckedListBox1.GetItemChecked(i) = True Then
ds.Tables(0).Rows(i).Item(10) = +1
da.Update(ds, "Students")
End If
I'm having an unusual problem that I've never had with WR's before. I have a very user-driven program that interacts with a server of mine through webrequests. Depending on what the user's doing, it could end up sending a dozen requests/minute. This has never been a problem before, but for some reason system memory usage increases and doesn't stop increasing, as if something is cluttering it up for every webrequest that is sent out.
Is there a known problem with WR's like this? Or is it just a random screw up? I can get my system back up and running smoothly.
I have just upgraded(!) to VS2010, and opened my project from VS2008, which worked, and when i try to run i get a Pinvoke error due to stack imbalance. I am completely lost, on this error. What do i need to do to solve it. The error occurs at the If GetAsyncKeyState(8) Then part of the code below. It is detecting for a backspace being pressed. Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Long) As Integer

I've got a dll, written in C++ (which I have the source code for and have compiled it under VS2010)It has a function I want to call in VB
SHARED_FUNCTION int yasdiMasterInitialize(const char * iniFile,DWORD * pDriverNum );
I've declared it as follows:
<DllImport("yasdimaster.dll")> Public Function yasdiMasterInitialize(ByRef IniFile As String, ByRef DriverNum As UInt32) As Integer
End Function
as when I try and use it as follows I get a pInvoke error:
Console.WriteLine("Initialise:" & yasdiMasterInitialize("yasd.ini", Drivers))
From reading around this is something to do with the declaration but I don't know what to change as this is the first time I've tried calling a DLL.
Now I see that VB tells me that label arrays are no longer supported But I also see that VB2010 is providing the relevant logic to update each of the label array fields I was until today using VB2008, because after running this application it crashes with a report of stack overflow, I assume it is related to the label arrays, but have no idea. So I have upgraded to VB2010.
In VB2010, I note that the immediate window is reporting A first chance exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll Now I have used label arrays for showing columns of like data, generated by a for loop. What should I be using it its place, maybe a grid..
I created a class that I use for error logging. I have one method that accepts a parameter as an exception. With that exception, I created the error log and I write the message as well as the stack trace. With this, I'm finding that I'm not always getting detailed information. Usually, the stack trace shows me line number in which the error occurs, which allows me to pinpoint the issue.

I would like to know how to write the code for increasing number.For example. When I type a number in a textbox, after I pressed a button, it will increase from the number I've typed in the textbox with 1.For example : if i type 100 in the textbox,the number will go on.

i'm writing a program that has two forms. i call the second form with this code
If Label2.Font.Bold = True And Label2.Visible = True Then
CollEdit = Coll(2)
Me.Enabled = False

and when the second form exits, it does this:
Private Sub frmCollEdit_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
'get back the collection
Dim retColl As Collection, i, j As Integer, pix(MaxPix) As String
[code]....
my problem is thus:
when the second (child) form is closed, the declaration
pix(MaxPix) As String
throws the stackoverflow error. MaxPix is a constant =200.

I have an app that calls a DLL, and passes a string to it (by reference). The DLL then fills the string and passes it back to the app. Before calling the DLL, the string must be sized correctly to fit the data the DLL is going to pass it. In the past (using VB.NET 2003) I just initialized the string with the correct number of spaces. This always seemed silly to me and I'm wondering if, in VB.NET 2010, there is a way to do this using a number to define the size?
View 2 RepliesNow all went well about from using the structure correctly. The working of the structure was perfect. How ever i missed Two important issues. The structure needed a fixed size of 10 items (9 in programming terms starting from 0) And also out of the 5 items allowed to be chosen as one of the member types for the structure a limit of 5 items of that particular type.

I have a small page, with a button on it. When I click the button I'd like the code to look at a a field (call the field "InvoiceNumber") in a table (call it "InvoiceTable"), take the last number stored, increment it by "1" then store it back in the "InvoiceTable" and display the new invoice number on the page.Currently the button is called "New Invoice", so clicking this button is going to create a new invoice, with a number one newer than the latest one in the table.

View 3 RepliesI am currently running through a loop with 20 threads. These loops contain a series of 3 HTTPWebRequests (relatively CPU intensive). At the beginning, CPU usage never spiked above 10%. After about 7 hours of run time, CPU is spiking up to over 40%. I believe that this will eventually lead to the program crashing (it has before in less time, I modified some things and it seems to be running longer). What kind of intense CPU spikes are associated with threading? More importantly, how can the duration of runtime affect CPU usage by so much?
