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 want to download thousands of files from the web and save them locally. What is the most efficient way? It is important the failures timeout within 10 seconds.
Is there a better way to stream one stream into another? Maybe a smaller buffer, like 1024 bytes at a time, is more efficient for large files?

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).

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?
View 1 RepliesThe 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.
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.

View 1 RepliesRecently 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?

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.
I made a application in VB.Net. But some users face crash upon startup. That is "A problem caused this program from working correctly" with just one button "Close the program". Since there are lot of things happening when the app loads

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?
