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. [code]
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 have an error when im using a function in dll. i declare this( "Private Declare Function SetChannel Lib "StreamReader.dll" (ByVal freq As Long, ByVal smyb As Long, ByVal pol As Long, ByVal fec As Long, ByVal lof1 As Long, ByVal lof2 As Long, ByVal lofsw As Long) As Boolean") [Code]
this is that error"A call to PInvoke function 'skynet!WindowsApplication1.Form1::SetChannel' 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.".
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.
I have created a webcam application in vb2010, when I run the app I get a run time error, please see below PInvokeStackImbalance was detected Message: A call to PInvoke function 'WebCam!WindowsApplication1.WebCamMainForm::SendMessage' 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.

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
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 have just a form in my VB.Net project and even when I try debugging that - there is nothing going on besides the form being loaded - I get the error: No symbols are loaded for any call stack frame. The source code cannot be displayed.
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.
The Form Designer in the IDE is no longer working properly. When I create a new project, the Form Designer will work, but after I save it and close the IDE and reopen the next day the Form Designer no longer shows the form and instead says "To prevent possible data loss before loading the designer, the following errors must be resolved: An Error occurred while parsing EntityName.Line 2, position 62" If I click ignore and continue, then it just displays a blank form with no controls. The problem appears to have started after I unistalled and reinstalled VB2008 Express.
what i need to do is open a txt file, read line by line, decode each line into an array and display. Now all works ok apart from one line.
sTextLine = objReader.ReadLine() <-- Value of string cannot be converted.
full code here ------------- Dim objReader As New System.IO.StreamReader(sOpenFile.Text) Dim sTextLine As New ArrayList() Dim sText As String = "" Dim i As Integer = 0
When a error occur it easy to know at witch line the error occur within the Exception class, but Is there a way to know what is the Code line itself?[code]...
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 need to write a VB.NET code to reverse the given characters using a stack.Input: 'S','T','A','C','K' So far I have input the letters, but I don't know how to get the console to reverse it. I'm a beginner to programming so please excuse my ignorance.

Im having problem downgrading because it will show error from resource file that has 4.0.0.0 in the line .. I try changing it to 2.0.0.0 but now my body form will not show up. I tried removing my resource file and upload it again but still wont work.
I am trying to add a new row into a gridview but for some reason i'm having a problem in the for loop.Directly goes to dtCurrentTable.Rows.Add(drCurrentRow) and of course, have an error "'row' argument cannot be null.Parameter name: row", because the tcurrentTable.NewRow was not executed.
Why is this happening? Private Sub AddNewRowToGrid() Dim rowIndex As Integer = 0
I've got the following error log code which creates an error log and emails it to me, but I can't seem to figure out how to include the line number that the error occured at.[code]....
I wrote a software for auto-generating some lines of code. However when I do a copy and paste of that code in a class after reopening it again I confront an Inconsistent Line Ending Erros.[code]...
In my code I'm using the Try-Catch functionality. All errors are written to the event viewer.I do it now with identifying the lines of code with a number.
How would i go about reading a file Line by Line that within that line The values are delimited by " Example of the data:
"bob" "cat" "1243" "steve" dog" "6789"
I've started this with this code but not sure how to go about the next stage:
Using MyReader As New _ Microsoft.VisualBasic.FileIO.TextFieldParser(My.Application.Info.DirectoryPath & "Records28112011.jd") MyReader.TextFieldType = FileIO.FieldType.Delimited
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.
