My app is a tray icon which scans the Outlook Inbox periodically. It seems, from testing in my VMWare WinXP machine, that the app stops Windows from shutting down. I press StartShutdown but nothing happens. I have to exit the app first then StartShutdown will shutdown the PC.

Is there a property setting that prevents an empty row from being displayed in a DGV? I have a DGV that is populated manually, the dataset that contains the data has 2 rows in it. The DGV contains those 2 rows of data plus an empty one. The return value of the DataAdapter Fill is also 2.
View 2 RepliesI am using WM_QUERYENDSESSION to detect Windows shutting down in my vb.net app, but the complexity is that I need to quickly load a console application during this code to do some cleanup. It is looking like the console

I am wondering if I can use VB.NET(I am using visual studio 2010 express) to get and set a environment variable.
I want to add path of my application on system environment. I want to preserve what is already there and then I wan to add my string. This can be done by getting value of PATH and then append my string then re writing it.
I have 2 questions here:
How to get/set system variable in vb.net 2010? Will it be on the fly, I mean will it be immediatly avaialble in dos prompt or there will be delay?
As just for experiment i opened a command prompt then updated the PATH variable manually and it was not updated. I am wondering it I do it through programe it will be same.
I have a program with the line process.start("shutdown", "-s -f -t 00") However, when it's executed, everything exits, and the logging off text appears, then the screen blackens out and there's only the mouse pointer. Nothing can be done like opening the task manager, I just have to shut it down using the main button, holding it for 7 sec.

I have a windows forms application that has no form and it runs in the background. It using a webbrowser control to get information off the internet.The program is that when I add the event handler:webbrowser.documentcompleted the program just shuts down. If i put a message box after the event handler then it works just fine because the webrowser has time to load the document. How can I do some like console.readkey that you would do in a console application?

I have a VB.NET form that takes up the whole screen. On Windows XP, the taskbar is not displayed when moving the mouse to the bottom of the screen. I have auto-hide set, and the taskbar is not locked. I tried the same thing on a Vista computer and it works fine. What am I missing on Windows XP? I need the auto-hide feature to work for my app like it does for other Windows apps.
View 1 RepliesI added an splash screen to my app. Then in the project settings I selected it to be used for the splash screen. Now my app won't close when I try to exit my app. I have 'When Last Form Closes' selected for the shutdown mode. So I'm guessing the splash screen is calling Hide() instead of Close(). I can't find a way to get access to the splash screen object so I can try callling Close().
View 6 RepliesI have written an application that sits in the systray and monitors a database for me. The problem is that this application is stopping some of my clients computers from shutting down, I assume because the app is still running when the computer is trying to shut down.
What I need to know is if there is a way that my application can tell when the computer is shutting down, so that I can close my application and therefore allow the computer to shut down.

I was in correspondence with someone using my program and he verified that on his system, XP won't shutdown/restart either if my program is running.
Basically what happens is when XP gets to my program in the shutdown process to terminate it, the whole shutdown/restart just stops. I have to exit my program, then start the shutdown again.
The person sent me an image of some threads that were still running after the shutdown process halted and I was curious if anyone might be able to shed some light on this info and what to do about these threads.
These are the threads that are running and what they do: mscoree.dll - a module containing the .NET Framework functions. mscorwks.dll - Microsoft .NET Runtime Common Language Runtime gdiplus.dll - contains libraries for the GDI graphics interface.

I have created a custom combo that automatically drops when the combo receives focus. When the user uses the mouse to click on another control or the Windows Form the combo list is undropped but the click on the other control is never fired. Is there a way to avoid what appears to the user as a need to double click?
I use the 'TransparencyKey' feature on my form to make a 'Panel' control transparent so i can see a program thats running underneath my form. If i try and do a screen grab (Capture a picture) of my form it only grabs a image of the background of my desktop and the program below and not my form.
If i use the normal Windows 'PrtScrn' key to grab a still image it manages to capture my form and underlying programs fine. This appears to be a limitation of transparencykey because as soon as you disable/remove it the screen grab works fine on the form. how to resolve this problem as removing the 'TransparencyKey' feature is not a option as i require this for my program
see the attached image for a better description of the problem
Image on 'Left' shows the transparent window viewing the desktop and program beneath. Image on the right shows the captured image and it completely missing the form and transparent window from the shot.

View 3 RepliesI wrote a program that is a system tray app that has no user interface. The issue is that when you shutdown, log off, or restart the PC the app does not shutdown and the user has the "End Now" message box pop up.
The only thing running on this app is that it is listening to a port for communication.
I do not have any code in the form closing event as that is what I want just to close.

View 3 RepliesI have a sub that I just discovered does not work for my windows 7 users but works fine for my windows XP users. This is basically a sub for a ping monitor to ping devices on a timer. What happens is that when the windows 7 user tries to ping, it always reports "down" on a windows 7 whether actually up or down. But, windows xp will report correctly with "up". 3 different windows 7 boxes, users say it worked before. Can't quite debug correctly as i'm on xp myself and it works just fine. Also, I haven't changed anything in the code in quite awhile and this is a recent bug that just started.
