How can i increasing stack size on my ui thread from within the app?

I 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?

View 4 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.

I wanted to add more functionality to allow user to increase the size of images that have been retrieved in the Picture Box. How to do so?
this is what I want it to do. On the label, I put a little image (a question mark icon). When hovered, a bigger image would appear. But the problem is, some other "labels" is going on top of the bigger image. And also, the bigger image, gets cropped when it reaches the border of "groupbox"

The file size of the attachment is 396KB, upon the recipient receiving the email outlook shows the file size as 543Kb. Strange thing is if I send an email with the same attachment using outlook the file size is 396Kb.I understand that file sizes can increase due to the attachment being base 64 encoded as opposed to just raw binary.What I am failing to see is why outlook send a file which is 396KB in size but in code when sending it, the same file is 543Kb.
I'm trying to code an 'increase' button to prompt a user to input a rate by which to increase select prices in an array.It should request the increased rate, then request a number from one to five, representing which price in the array to increase.Then, if 'increase' button is selected again and another number from one to five is chosen, then that element should be increased.It's working, but all the numbers in the array are changed. And, when I hit the increase button again, the array is repopulated below the first price increases instead of only replacing the designated price.
'declare 5 element array of prices
Dim prices() As Double = {12.2, 8.5, 12, 50, 2.4}
Dim rateIncrease As Decimal
Dim isConverted As Boolean

In one application, I need use 4 simultaneous threads.When the threads finished, I need to update the text of a TextBox.So, I create 4 Textbox, and I wanna the threads change the text to FINISHED.Each thread change one distinct TB.I use this "example"

The problem is, I have an error in the red lines.The error is: INVALIDOPERATIONEXCEPTION "Cross-Thread operation not valid: Control tbPlaca1 Accessed from a thread other than the thread it was created on."I don't use cross threading. Each TB only was accessed for the correspondent thread, and for the "main program".
This is the error message I am getting:
"Cross-thread operation not valid: Control 'Panel1' accessed from a thread other than the thread it was created on." The reason I am getting this error is because I am opening up a new form and then calling these three things:
Panel1.Show()
Label1.Show()
Label2.Show()
why I get this error message because it doesn't occur normally if I open Form2 after closing Form1, it only occurs when I open Form2 after closing Form4.

Would anyone be able to help me here please. I'm fairly new to VB.net and threading so im just trying to figure out what is happening.When I debug this I am getting the error thread operation not valid: Control 'ProgressBar1' accessed from a thread other than the thread it was created on.
I'm a little lost as to why the error is occuring or how to fix it. I've had to put the progress bar in a separate thread otherwise the GUI crashes
