IDE :: Dfsvc.exe Causes ClickOnce Win App Crash?
Feb 19, 2007
We have one user who has run into problem on this CilickOnce win app today.When she clicked the Install button on the publish.htm hosted on the network, a message said:dfsvc.exe has encountered a problem and needs to close. However the app still launched when she clicks any button on the pop up message box, then later crashes in a crystal report viewer with system.reflection.target invocation exception if she enter that particular area.I googled dfsvc.exe. Some posts said it is a virus while others said it is ClickOnce engine. I have many other users who are on the same version and are running the same OS settings without any of the above mentioned trouble.I am not sure if the dfsvc.exe error is related to the reflection eception or not.

I have written a very small windows console application that got uploaded to an internal company portal. Basically this thing only looks for a registry key and if it doesn't find it, then it creates it. After that it populates a String value and exits. My issue is that when I provide this tool to our L2 support group they put it on an intranet portal.

I have a long running (kiosk display application) WPF vb.NET App which is crashing after about 15 hours.
I've tested it twice, it's crashed almost at the exact same time.
I have no idea where to start.

I have recently implemented to following code on a good deal of my forms.
Public Overrides Function InitializeLifetimeService() As Object
Return Nothing
End Function
It has worked great to solve some of my odd application hangs when the application has been running > 1 week.However, when the user closes the program I now get an Application Crash screen.how to stop this? how to put it back to "normal" with a global variable?
Public Overrides Function InitializeLifetimeService() As Object
if readytoExit then
' Return... not nothing?[code]......

Maybe a strange question, but I need to test the stability and error procedures of the host process (caller) that accesses COM objects. Therefore I need some easy/short methods to let the COM object(s) crash itself.
Addition 1: With crash I mean the type of crash that can take the caller down also.
Addition 2: I own both the code of the caller as the COM server.

I'm currently trying to send the SB_GETTEXT message to a status bar, but it always crash and I don't why (the SB_GETTEXTLENGTH works fine, but not the SB_GETTEXT). Below is a VBA code I tried to use in Excel to read the status bar text of Worpad. The first code using WM_GETTEXT works well, but the second code that uses SB_GETTEXT always crashes.

I've made a client beta software in VB and use ClickOnce to install/upgrade clients. Everything works OK until I upgraded to .NET 3.5 SP1 and implemented SQL Server Compact 3.5.All clients got an upgrading error. The solution was a reinstall from the download page. All clients works OK exept one; The client crash on startup on a Vista 64-bit PC. I cant' find the error?Tool/platform:VB / Visual Studio 2008 SP1.NET Framework 3.5 SP1The following prerequisites are required: * Windows Installer 3.1 * .NET Framework 3.5 SP1 * Microsoft Visual Studio 2008 Report Viewer * SQL Server Compact 3.5 Morten Dahl

Basically, I have a Web Browser object on a Visual Basic form. However, about 5 seconds after it finishes loading ANY webpage, the entire program stops responding. I figured the issue was related to internet explorer, so I updated to Internet Explorer 9 Beta and the issue is fixed (this is a very strange fix)!!! However, Internet Explorer 9 is not available for Windows XP. what might be causing this and a possible solution for computers that are running XP?

The scenario is this: VB.net 2003 connecting to access 2003 using Jet 4.0 SP8 and MDAC 2.7 SP1.On a particular client machine with XP SP2, while trying to fill a dataset it crashes fantastically without ANY error message. the exe just disappears from the task manager.I use a Module to launch the MainApp form, if I try to connect within the Module BEFORE calling the:
Code:
dim MainApp as new MainApp
application.run(MainApp)
...the datasets work normally, but if I do it inside the Form_Load (or anywhere inside the form) it presents the previously mentioned fatal crash.I have updated the clients machine with the SP1 for .NET 1.1 with no luck.Now, in a desperate attempt, I have installed VB.NET 03 in the client machine and with the dev env it works fine, but if I try to run the executable from outside, it crashes again. No error message from the exception handling inside the app, no unhandled errors from the framework or the OS, it just vanishes from the task manager.I tried to reinstall MDAC and Jet but the installers find the previous files and won't update with the new ones. Tried also reinstalling .NET framework and the error persists.

I have an Access 2007 database that runs constantly, the form on the database basically runs a timer every 10 seconds and runs a Macro. The problem I have is that when the backups run at night the network connection the database is on disconnects for the backup, so the database crashes with the error.
"Your Network Access was interrupted. To continue, close this database, and then open it again."
What I would like to do is create a small VB Application that runs on the machine that the database runs on, detects when the database has a problem, closes down the database process then restarts the database.

There is a bug report [URL] on serious problems that can occur if you are using a USB to serial port converter and the user pulls the USB while the serial port is in use. Apparently the bug is still present in VB2010, and Microsoft still has the bug closed.

Recently one of my clients started experiencing a very unusual problem. When they try to print from the program I developed their whole system crashes without any error messages or warnings. This problem started recently (they have been using this software for over 2 years).
I used VB.NET 2003 (.NET Framework 1.1) to develop the software, my clients have Windows XP Pro. At first I thought that the problem was in their printer driver. I contacted their IT department and after several weeks of testing they conlcluded that the problem is somehow related to my software (this issue never happened when the client is printing from any other program). To print, I have created a group of classes that create and print reports. The main class subclasses PrintDocument then I use PrintPreviewDialog to display the preview and give the client the option to setup page settings, etc. The code runs without problem on my development machines and up until recently without problem on the client system as well. I did intall an upgrade recently that was related to printing, but all I did was to modify the print output, the upgrade did not modified any of the printing functions.
I tried to find information on the Internet, but coudln't find anything. I wonder if migrating the solution to .NET Framework 2.0 will solve this problem?

whenever I save anything in it, VS crashes it doesn't seem to matter what file I save in any of the projects within.It also seems to actually save all the files; just crashes when it's done is my guess...

I have a backup program that is currently running in our Corporate Environment on about 70 machines. A mixture of Laptops, Desktops and Windows (xp-32, vista-32, vista-64, 7-32-7-64) with no problems.
There is one exception, and it's the reason I'm posting here for assistance.On one machine that is a Dell Latitude running Windows 7 64 bit with .Net 4 Framework installed the console application will crash immediately before it starts Sub Main. It simply give the generic windows error "A problem caused the program to stop working correctly." with no option to see debug info.

I've got quite a big application and I've just started noticing that not all runtime errors cause an error.
for example if I call a function that executes an SQL query and the query string uses invalid syntax or refers to a field that doesn't exist then that would normally cause an error at runtime. But it doesn't - as soon as it hits the error the function simply returns to the caller.
If I enclose the code in a try/catch then the error is trapped but, while developing, I just want a good old runtime error but not getting one.

Our automatic crash-report system has started sending in more and more reports of this kind of crash[code]...
I was under the impression that Arial is supposed to be available everywhere on Windows, and, when a Font cannot be found windows would revert to another font+style that does exist.
What is the correct way to handle this? My app needs to define a number of standard fonts for different display elements. So far I've hardcoded Arial, Courier New, Comic Sans Serif and Times New Roman and I've been getting crash report for all of them.

I'm working on a VB2008 project that references two Access databases using Provider=Microsoft.Jet.OLEDB.4.0; It would seem if the user does not have MSOffice on their machine, the program crashes with a "XXX stopped working" on startup on Vista and Win7.I thought that Windows had XP and above had Jet functionality built in?

I have just suffered a crash after trying to assign an image file to a button on a toolstrip on my applications main form. The ToolStrip was in a ToolStripContainer and already had some images assigned. Initially I was trying to insert a bitmap image which proved to be unsuitable (cosmetically) so I assigned a .Png file instead (using Project Resources file import) which caused the problem.The crash wiped out the toolstrip and also blanked out the MenuStrip on the form whilst still leaving references to them in the "Form".designer.vb file. Any attempt to resurrect either just led to more errors. I'm not attempting to detail all the error messages here (too many) and I have worked round the problem by resorting to an earlier backup.I'm really wondering if anybody had experienced similar problems and/or had any advice on the best way to add images (and what type of image files are OK and which might cause problems).

I am running into problems with my compiled .exe on other machines. On some computers it works, on others it doesn't (all using Windows XP with the .NET framework installed). When I run the .exe on some computers it crashes right away and hits the 'Send error report' dialog. On others it runs just fine. I'm pretty sure this has to do with missing components, but how can I fix it so it works for all computers? How do I find out which components are missing?

Whenever I have an error, the program doesn't crash. It just stop executing code. The error message goes to the debug window (which I can't see until I end the program). If I have a button for example I can still click this and execute the code inside it.
I never thought I'd be asking this, but how do I make my programs crash again?

my system crashed and I lost all of my VB.net projects. IT says the hard drive is shot and they cannot recover the files. However, I have all of the project's debug files on a network drive that was not impacted because the info is stored on a shared sever.What I have are the following files: (These were pulled from the DEBUG folder)
Executible
Program Debug Database
XML Document
[code].....
Can I recover the project using just these files?

I am trying to write an alarm clock and I am working on the input check. now the way I am doing it is first checking to make sure that the input is 0-9 and a : . but when i run the code it crashes at the substring saying
Index and length must refer to a location within the string. Parameter name: length
I don't get why its giving me this error when I replaced it with a static number it worked fine. I don't know why the variable makes it crash.
Dim temp, temp1 As String
temp = TXTinput.Text
For x As Integer = 0 To 4

I realize the program as of now has no output, and that's fine. I have an ofdOpenDialog that I didn't include in this post as it seems kind of irrelevant, that part works fine, browse button to a path, outputs the path in a textbox for the users reference. I have the only user-entered text box set to on change: [code]But when I do this, the program just instantly stops responding. Is that a problem with my code or is the text file it's reading too big? ( Roughly 3-4000 lines.) I read somethign about a buffer once, should I set that larger somehow?
