C++ - Unhandled AccessViolationException Error Calling A DLL?
Oct 6, 2011I'm trying to call a C++-compiled DLL from VB.net and I'm running into some problems. Seems like there's an obvious solution, but I can't figure it out.Here is the function declaration in C++:
MyFunction(int trailingaveragesize, double sigmasize, int myflag, int sizeSeries, double *Xdata, double *Ydata, int sizeinputparameter, int *averagePairs, double *PositionsSize, double *PnLSize)
Here is how I'm calling it in VB.Net:

Calling A DLL From .NET - Error Occurs On Windows 7?
Feb 8, 2012I have a VB6 DLL that wraps a call to a 3rd party component. When I call my DLL from VB6, everything works fine, but when I call it from vb.net (2.0 framework targeted - VS2010) I get this error:
AccessViolationException occurred
Attempted to read or write protected memory. This is often an indication that other memory is corrupt.This error only occurs on Windows 7 (Windows XP clients work fine).I've looked this up and all the articles I found talked about the declaration not being correct.I am not declaring any APIs calls though, the 3rd party component is early bound in my VB6 DLL.I can run the DLL, set a breakpoint,and it goes into my VB6 function, but errors calling a function in the 3rd party component.My VB6 DLL takes 3 string and one 32bit numeric (long in VB6) parameters. The 3rd party's DLL function that I am calling is taking a string (bstrDNSID as string is what Intellisense shows in VB6). This is where it errors.
Update: None of the marshalling has helped, so I tried creating a test sub in my VB6 DLL. I hardcoded all the values within the DLL's test sub. It works fine when called from VB6, but gives the same error as above when running from .NET. Also of interest, when I have the VB6 DLL running from the VB6 IDE, I do not get the error when calling the DLL from .NET.
Calling GetProductInfo Gets An PInvokeStackImbalance Error
Aug 24, 2011I am testing this on Win 7 Ultimate and it generates an error: PInvokeStackImbalance was detected Message: A call to PInvoke function'WindowsApplication1!WindowsApplication1.Form1::GetProductInfo' 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.

.net - Generic Error In GDI+ When Calling Bitmap.getHBitmap()?
Feb 18, 2010I'm writing an application which as part of it draws an image on a Logitech G15v2 keyboard's LCD. For the most part the function works fine, but after a while of running, one of the lines throws a "Generic Error in GDI+" The problem, according to a stack trace, is in Bitmap.GetHbitmap():
at System.Drawing.Bitmap.GetHbitmap(Color background)
at System.Drawing.Bitmap.GetHbitmap()
at CSCI171_TermProject.G15.Tick(Single Interval) in C:UsersSukasaCSCI171Term ProjectCSCI171-TermProjectG15.vb:line 45"
I've read a few threads mentioning this error, but that was in the context of saving a file, not getting its associated HBitmap. Would anyone with more experience with GDI+?For better reference, here's the full code module:
Public Module G15
Private G15 As New G15Lib.G15Interface
Private G15BaseImage As New Bitmap("GFXG15-BGImg.png")

View 2 RepliesFunction Calling Itself, Can't Dodge StackOverflow Error
Oct 7, 2011I understand that this is bad programming practice and redundant coding but I am curios.
I am simply counting a number up to 9999999 in a while loop. The Add() function simply increases that number and prints it out.
Inside the Add() Function I call the Add() function.
My program successfully prints out 12000ish numbers before I get a StackOverflow Exception.
So my question = Is there any way to ignore this error and keep counting?
I have tried On Error Resume, Try/Catch, and throw
My code is as follows.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
While number1 < 9999999

Sql - Calling Stored Procedure From .net Timeout Error?
Apr 23, 2010When calling a stored procedure from vb.net is there a default SQL timeout time if no timeout is specified in the connection string?I am unsure if there is a CommandTimeout specified in the connection string but am going through all the possibilites.
Example if no results after 30 seconds (or more) throw:
`System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.`SQL Profiler says that the script runs and ends in 30 seconds when the program timesout..Tthe script runs without error in about 1 minute 45 seconds by itself in SQL server.

Calling A Class - Get An Error When Trying To Call The Sub/function The Normal Way?
Sep 1, 2009I have a Windows form Application that I am creating, could also be a Windows Service that I need to run.There are basically 2 Classes that were converted from java to vb.net and 1 xml file to this. for testing purposes I would like to use the Button.click event to manually run the code.However i get an error when trying to call the sub/function the normal way.I even tried to put this classes information in the Public Class Form1 but it keeps on giving me errors.This is the Sub:
Shared Sub Main(ByVal args() As String)
so how do I call it from a Button.click event?
normally i would just do a "call main()" and it works however this time it is not because of the (byVal args() as string)

Calling A Web Service That Requires Credentials: Error: A Security Token Is Required?

Runtime '429' ActiveX Cannon Create Object Error, Calling .NET From MSO On Vista
Oct 9, 2009Our VB.NET application has a .NET dll, with a registered TLB file; so that VBA in Microsoft Word and Microsoft Excel can call into the application. The application functions correctly except when it is called into via MSO on Vista. This functions correctly on Windows XP machines but on Windows Vista and Windows 7 machines it is returning a 429 error. A reference to the TLB file can be assigned in the VBA References dialog box, on Vista.It doesn't appear to be a problem in our application as a simple Test libary does the same thing. Microsoft Applications have been 'Run As' Adminstrator, and Vista UAC is turned off, but I am thinking there is perhaps a security issue?

.NET Application Receiving 503 Service Unavailable Error When Calling Web Service?
Apr 28, 2009This is a bit of unusual problem that I'm experiencing, but recently one of the users of a production application started reporting errors in the system. These were traced to a 503 Service Unavailable error when making a call to a web service used by the application.
Now here's the odd part, only the one user is affected by this issue. Other users of the application have not reported any errors. When the user logged on to a different machine that worked for another user, they still received the error.

Asp.net - Server Error Asks For Error Specific Page Instead Of Error Details?
Mar 6, 2012When I deployed my project on a server, in certain circumstances, I get an error page that indicates I should create a custom error page. I was wondering how exactly I would implement this custom error page the server asks for to give me a precise and helpful message or preferably, how I would get the error to just display on the main page?This is the error message I got below
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
<!-- Web.Config Configuration File -->
<configuration>
<system.web>

Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

Calling .NET Dll From C++?
Aug 3, 2010I have a C++ application exe that uses a C++ dll. I don't have the source of this C++ application and cannot rebuild it. But I know that it uses the traditional LoadLibrary and GetProcAddress to access individual functions in the dll.For some reasons, I want to replace the C++ dll with a VB.NET dll. The dll is not and ActiveX and is therefore not registered.I think I cannot use a class but a module since the C++ exe application does not expect any class in the dll. In all my attempts, I could not have the inner functions of the VB.NET to be called by the C++ exe.How should I write the VB.NET dll?
