VS 2008 Form Crashes If A Database Object Is On It?
May 27, 2010
I have an access database that I have imported into VB2008 through the data sources and have placed a table onto a form via drag and drop.Now whenever the form is displayed it crashes VS. I have tried deleting everything off the form, only leaving the database dataset, table binding source, table adapter and adapter manager on the form, even then it still crashes.I am running Windows 7 64bit, 2 of my peers are running Win 7 as well and are having this same issue, however the computers at our college are running Windows XP and have no problem at all with it.

I have a vb.net 2005 application that connects to an access database. I use Access Database Engine 2007 to connect to to this database.
Everything worked fine until i install MS Office 2010. After this, the application started to crash, returning the error 'application has stopped working'.
I've a Windows Seven Enterprise SP1 32bits.
When i debug the application, visual studio also crashes. I get the following error, closing an OleDbConnection: 'vshost.exe stopped working'.
I decided to run some tests. I installed my application on 2 virtual machines: a windows xp sp3 and a windows 7. When i installed ACE 2007 everything worked fine, but when i installed ACE 2010, thats when the problems began. This behavior ocurred on both machines.

I have a VB application in .NET Framework 2.0 and I'm using VS 2008 Professional for development. The application is running without any problem on some PCs and it's not running on one of the PCs. To make sure that nothing is wrong with the that specific PC, I tried to reproduce the issue on my machine. So I formatted my PC and reinstalled everything. After installing .NET Framework and required drivers, the ran the application i got the same error. Then I installed VS 2008 and open the project to debug my code and then I realized that the exception is being thrown on this line:
********************************
Private Sub btnEnterRecords_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnEnterRecords.Click

I've created a form that has a timer control. When this form loads it counts down before running a procedure. Simple.
Now I want to subclass this form in a new VB.NET project to so that another form inherits this form (an it's timer functionality) and runs a different procedure on this new form.My problem is that when I create the form in my new project the timer from the parent form seems to be running and when it's time is up it runs and code and crashes the VS environment.
I've searched high and low but have only found references to making sure the timer is disabled at design time. I've done this on the parent form but in this parent form's Load event the timer is enabled.... the purpose of the form. So when the child form loads it is enabling the timer. How can I work around this? Can I enable the timer from the child form? Timer is not visible when the child form loads so how do I manipulate it?

I have 2 modules and 2 forms. In the module1, I initiated the form classes and also here I have my public appexit() method.In module2, I have another class(in the form of a keyboard done by code). Form2 use this class as its control.I have:
form1_closing()
mybase.close()

I've been writing an application that gathers various details from a PC and writes the info to an SQL database. It works fine on my PC and on several others that I have been testing on, but I just ran it from one other machine and the app instantly crashes with a "testipm.exe has encountered a problem and needs to close" message. This is logged in the event log every time the user tries to run the program:
Event Type:Error
Event Source:.NET Runtime 2.0 Error Reporting
Event Category:None
Event ID:5000

We have an application that works well on XP/Pro, Vista, Windows 7, Windows 2003 Server, Windows 2008 Server (32 bit) but is problematic on Windows 2008 Server (64 bit). The application uses an unsigned activeX control which may or may not be related to the problem. To install we need to add the program name and regsvr32 as DEP exceptions. Once that is done the application installs correctly and operates normally except when the application closes.
If a user clicks the 'exit' button our code basically says 'unload me' (where me = the main form of the application) and there is no code in the form_unload section of the program.
Everything works well on every Windows platform except Win 2008 64 bit where we get
APPCRASH
Application Name: PDFPrint.exe
Application Version: 10.10.0.18
Application Timestamp: 4d238253
[Code].....
After we continue to close the program we see a message box with run time error 216 at 00002B24 message.

I have an ExtendedDateTimePicker control on my form. When I attempt to change the "ShowCheckBox" property to true, VS2008 stops responding and eventually exits the application; losing any unsaved changes.
I then tried to changed the property in code and the same result.
I want the control's value to be blank when it initializes.

But I'm running into a problem: whenever I open the project on my new laptop, it crashes!I can open other projects on my new laptop, including some copied from my old laptop. I can also open the project in question on my old laptop. So the problem must be some combination of things in the project, and the fact that it was moved

whenever my program crashes at college, an error message pops up in a window which tells me why the program crashed and points to the line of code which made the program crash. I have recently taken the program home to finish on my own computer but now whenever it crashes nothing pops up to tell me why it has just crashed.

the error code points to a Stack-Overflow I can not pin the offending code down because the software works faultlessly on some computers after deployment but on others the crash occurs when a Gantt chart gets redrawn after changing activity dates. All the computers are situated on the same LAN and connect to the same SQL server 2008 database.The application has been developed with Visual Studio 2008.
I used the same install disk on all the computers and they are all using the same date/time format. The crashes occur on both 32 - and 64 bit machines.
The error message:
Stopped working
Problem signature:
Problem Event Name: APPCRASH
Application Name: Pfisterer Project Manager.exe

I'm having this problem with my code and cannot seem to get past it although it was working fine before. The error is "An error occurred creating the form. See Exception.InnerException for details. The error is: Object reference not set to an instance of an object." The code is:
CODE:
I am trying to get information to be pulled out of a database and show in text boxes on another form (frmviewsdets). The error occurs when it gets to the line frmviewsdets.txtsnumber.Text = rdr("StudentNumber") and even when a breakpoint is applied there it just moves on to the next and so on.
I have tried to show frmviewsdets before I pull the data out of the database beut I get the same message.

I have a solution with several Projects in it. There is a Windows App project (called ImportClient), and a Class Library (Import.Library). The Import.Library has functions to perform data imports (I have other applications in the solution that also need to call it). But the interactive application, I want to be able to pass in some form controls, and have it update the GUI. No problem. But, I also want to execute a DoEvents() so that the loop execution doesn't hang other interaction to the app.
So, ImportClient has a reference to Import.Library. But I can't add a reference to ImportClient to the Import.Library, because the compiler complains about circular reference, etc. I don't know how else to define the My.Application object of ImportClient as a parameter to the data function in ImportLibrary.
(I realize this is a dumb question - problem is, for this project I have a tight timeline, and haven't learned how to do the BackgroundWorker process. If you think I could pick it up quickly, I'm open to some hints about how to update the progress bar on the GUI, and how to pause / cancel the background task.)

I've got 3 forms that have exactly the same functions, so I decided to create an interface.
public Interface IExample
public sub Add()
Public sub Edit()
[code]....
At this point, objfrmExample is now instantiated, even though I've not done a "objfrmExpample = new [what-goes-here?] " and I'm curious as to why.I could possibly guess that because you cannot instantiate an interface variable, then vb.net automatically creates an instance. But thats just a guess. The question is , what is meant by declaring a variable of type Interface, and how does it work?
