Api "unbalanced The Stack" Error
Mar 21, 2011
I recall in C++ that there is a function named System that can execute an MS-DOS Batch command (such as echo, pause or title) and have searched for an equivalent in VB.NET
Finally I found the api HERE and tried it
Module Program
Declare Function sys Lib "msvcrt.dll" Alias "system" (ByVal command As String) As Integer
[CODE]...
After "hello world!" outputs to the console I see this error QuoteA call to PInvoke function 'ConsoleApplication1!ConsoleApplication1.Program::sys' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.
Why this error occurs or a better way to declare the api? I am using .NET Framework 4.0.

The following code (calling proc DiskFreeSpace) throws an "unbalanced stack" error message.
Private Declare Function GetDiskFreeSpaceEx Lib "kernel32" Alias "GetDiskFreeSpaceExA" (ByVal lpDirectoryName As String, _
ByVal lpFreeBytesAvailableToCaller As Long, _
ByVal lpTotalNumberOfBytes As Long, _
ByVal lpTotalNumberOfFreeBytes As Long) As Long
[code]....
Additional note: My function does need to work for UNC paths also (local and/or network).

This code worked fine in WinForms under .NET 3.5, but since I've started using WPF and .NET 4.0, it no longer works (although I'm not sure if this is a coincidence or not). The purpose of this is to detect if a mouse button (or multiple mouse buttons) is being pressed outside of the application.[code]...

I'm converting some C# code to VB, but the VB code gives me an 'unbalanced the stack' error.A call to PInvoke function 'Application.WinPcap:: pcap_ findalldevs' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.This works fine. [code] Here I get the 'unbalanced the stack' error on the line: "If pcap_findalldevs(tmpptr, err) = -1 Then".The only difference I see is "ref tmpptr" in the C# code, but I'm not sure how to translate that to VB.

could you tell me, why I get the stack overflow error on this code?
Dim ev As Double = datum.Year * 365 * 24 * 60 * 60
Dim honap As Double = datum.Month * 30 * 24 * 60 * 60
Dim nap As Double = datum.Day * 24 * 60 * 60
Dim masodpercek As Double = ev + honap + nap
The double datatype should be enough.

I have a program that sends out mass emails. My problem is that at the end of the program....I keep getting a "Stack Overflow" error and I cannot figure out where this might be happening. This program is a VB.Net 2005 console application which is ran manually from the command line. The code below that I have posted is what sends the actual email. I don't think it has anything to do with this error but my question is this. Do I need the highlighted line of code? I'm thinking I don't since the mail object is already being disposed...but I'm not positive.
Dim oEmail As New System.Net.Mail.MailMessage()
oEmail.From = New MailAddress(strSender)
oEmail.To.Add(strRecipient)
oEmail.Subject = strSubject

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.

In your actual programming experience, how did this knowledge of STACK and HEAP actually rescue you in real life? Any story from the trenches? Or is this concept good for filling up programming books and good for theory?

What I want to know is that in VB.net is it possible to get a stack overflow, and if so how is it caused. What I mean is, what sort of written code would cause a stack to overflow.

I've started using .Net's stack collection. The basic features I guess are the "pop" and "push", where you add or take off the top element of the stack (if you are referencing other elements in the stack then another collection type is probably better).[URL]..it appears that the Stack collection (like other collections) is basically an array with some window dressing (so you actually can see other elements). As far as I can tell, "popping" and "pushing" is changing the first element of the array. Shouldn't instead the final element be the "top" of the stack and be the one that is changed? Otherwise the program has to reindex all the other elements in the array every time a pop or push is made. This seems very inefficient. But this is what Microsoft's description appears to be saying what is happening.

My problem is that i need log the stack call. I know that i can put a breakpoint in code and choose the debug menu option "call stack", But that is not a solution for me, because i need all the methods called by the application, not only the last until the breakpoint.

I just started programming in VB.NET 2008 with the Express edition and have been having a blast so far. I thought a fun program to try and make would be an infix to postfix program.
I have five text boxes off to the side of my program that shows what is on the stack as you iterate through the equation. I'm wondering if it's possible to make these textboxes set to display what is at a certain index of a stack.
For example, if I pushed a "(" onto the stack, I would like the top box of my textboxes to update and show a "(". When something else is pushed onto the stack, say a "/", I would like the "(" to be displayed in the second box down, and the "/" to be displayed in the top box now.

We have this funky little ObjectDisposedException happening now and again. But only on production machines, of course ... can't recreate the issue on my dev unit. So I trotted on out to the Microsoft site to see what members of this exception I could use to figure out what's going on. Microsoft says that one of the members is StackTrace. I double and triple checked that I'm looking at .Net 1.1 information as I'm pretty sure that's what I'm using (how can I check that?). Here's the page I found - [URL]
So I go back to my program to write something useful to the event log so I can figure out what's going on. And when I look at the members of the ObjectDisposedException available to me I only see the following: GetBaseException, GetType, InnerException, Message, ObjectName, ToString.
what happened to my StackTrace member? I sure could use it if I could figure out how to get to it.

As a learning experience I decided to try and implement the Shunting Yard Algorithm(string calculator) using OOP. It was successful for as far as I took it, but it had one flaw. In order to get the stack to be accessible from the operators I had to declare it as shared, which meant that all versions of the calculator shared one stack. This very short piece of code illustrates what I came up with and the "flaw". [code] How can I maintain the functionality of anOP.add1 without declaring "something" as shared?

I'm writing this program in Visual Basic .NET to organize different fields of data, and I'm using profile slots through application settings to store the data for users. But, I ran into a stack overflow error in my SlotSelect.vb class. My best plausible guess for why this happens is that I'm using the wrong kind of variable container in the below sauce code, but my dilemma is that I don't know what specifically is going wrong.The code that the vshost is saying is the cause for the overflow was written from some code that I looked up on MSDN and other places for referring to objects in other classes, and I tried using other variants of it to see if it was any different. So far, nothing has worked, and it doesn't stop the error while compiling, much less in the code markup--it only catches it when it starts the application in debug after it finishes building

I'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 am trying to add (Push) whatever the user enters in (MyStack) into 5 different labels that should show the (UserResponse). The problem is I don't know how to display each element in a different label. For example:
- The first element that the user enters (UserResponse) should be in Label1
- The second element that the user enters (UserResponse) should be in Label2 etc.... up to label5.
Also, when I press (Pop) the elements should disappear (Last in first out).

In the context of the CLR in .NET how is stack space allocated and what is it typically limited by? For example: Can any given thread continue to add to the stack until memory runs out? If not; how does the CLR decide how much space to allocate and can it change its mind?
PS: Just to put some context on it this all started from a discussion on how to build a method that will calculate the Fibonacci sequence and one of the suggestions was a recursive function.

I am trying to make a calculator to calculate how many sheets of a product of varying thickness to put into a stack and how many stacks are required to make a whole pack, taking into account that some packs have no cover sheets and some have one at the bottom only and some have top and bottom.
As you can see there are a few variables and to make it harder is the way the stacks are made. No stack can be over 180mm and the last two stacks are halved to make the last two an even height (roughly).
I have a For Next loop and this would be okay if it wasn't for the 2 odd stacks at the end and the cover sheets.
This is what I have anyway.
CB = txtBottomCB.Text
lstDisplay.Items.Clear()
MaxBookHeight = (txtBookHeight.Text)

I have created quite a few web chats using VB.NET and ASP.NET and I'm just wondering how Stack Overflow handles messages being sent back to clients. Because web can only make requests and get responses back once, how does Stack Overflow handle messages? In my implementation I have a recursive loop that gets called every 1 second and makes an Ajax request to the server to get the latest messages, but I am thinking of using web services

In VB .NET, I know I can get a stack trace by looking at the value of ex.StackTrace when handling an exception. How can I get the functions on the stack when I am not handling an exception? I am looking to implement a logging system of some sort to record the steps the user takes prior to a crash to assist in debugging.
