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.

I have recently updated a legacy compact framework application to support Windows Mobile 6.5 but after going through my backwards compatability testing I have an issue with the WinCE 5 device.When attempting to run the application from both the EXE and the debugger I get the "An unhandled exception of type 'System.TypeLoadException' occurred in Unknown Module." exception but its not giving me any idea which dll / type it has issue with.The changes do work on the Windows Mobile 6.5 Motorola device and the Pocket PC 2003 Psion Device but not on the WinCE5 Psion device.Does anyone have any ideas how I can find out which reference is causing me the issue. I have tried removing the new references to the Symbol barcoding and imaging libraries but I am still getting the same error.OK, it looks like the .Net Compact Framework installation had corrupted some how. I flattened the device, reinstalled and everything appears to be working.
View 2 RepliesUsing Access 2003 and VB code, I have created a form with a number of labels. The labels will display an employee's names. I have named the labels name1, name2, name3...etc. Using an ADO data set and DCount I have determined the number of names in an Access table (the number of names can vary). What I want to do is for each record in succession to pick the first name and surname from the data set , combine them into a full name (this part has been successful), and then set the full name into the label caption in succession. Example: full name 1 into name1, full name 2 into name2, full name 3 into name3... until all names appear as labels on the form.
I created a counter to and a variable to increment the label number but when I address the caption property of the variable containing the new label (e.g. name1, name2..etc.) it throws an errer at runtime. Here is the code:

I've been programming a game recently and didn't want to make 99 weapons manually. I've tried making a loop do this for me. I've got the loop working, everything is perfect. But when I run the program and list all the Weapon(x).Name [x being any value between 0 & 99] they are all identical... HOWEVER. If I single step through the code it lists all the names from 0 to 99 perfectly fine. Why is it that single stepping through it produces what I want?
Private Sub CreateWeaponList()
Dim StatName(4) As String 'Creating 4 pre-made names for weapons
Dim WeaponName(4), RandomWeaponName As String 'Creating 4 more pre-made names for weapons
For x = 0 To 32
Weapons(x).Type = "Sword"

I'm developing in MVC2 using VB.NET and MySQL and ran into a problem trying to convert a simple SQL query to LINQ. SQL Query:
[Code]...
Looking at that query its easy to spot whats causing the error. Simply, the most inner query only returns 2 columns, while the query right above it is trying to SELECT 3, thus the Unknown Column Error. So why is this happening? What is wrong with my LINQ query?
I am using MySQL ODBC 3.51 Driver to connect odbc to MySQl.But it shows the following error.
[Code]...
I'm currently doing a project that includes access 2010 My question will be what driver can I use for an access 2010 *.accdb type file? For a *.mdb it works perfectly well with
ConnString ="Driver={Microsoft Access Driver (*.mdb)};Dbq=" & Application.StartupPath & "\CITSDB.mdb;Uid=Admin;Pwd=123;"
But, when I changed the mbd to accdb:
ConnString ="Driver={Microsoft Access Driver (*.accdb)};Dbq=" & Application.StartupPath & "\CITSDB.accdb;Uid=Admin;Pwd=123;"
It resulted in errors:
ERROR[HY000][Microsoft][ODBC Microsoft Access Driver]Could not find file '(unknown)'.
ERROR[IM006][Microsoft][ODBC Driver Manager]SQLSetConnetAttr failed
ERROR[HY000][Microsoft][ODBC Microsoft Access Driver]Could not find file '(unknown)'
And then it shows me that my code for
If dsLogin.Tables(0).Rows.Count = 1 Then
IndexOutOfRangeException was unhandled
Cannot find table 0
I knew it must be the driver but I don't know what accdb driver I can use for the connstring.
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.

I 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
application is not even loading, even though I can cause delays in the vb.net code. Is there a way to do this?
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?
View 11 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 am only running my app on Windows O/S e.g. 2000, XP The application is written in VS 2005, .NET 2 and VB.Net language
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've build a vb.net windows service which does nothing but ping a wcf webservice and handles sending a maintenance request to this same webservice at night time.

The windows service thread needs something todo.[code]....
View 2 RepliesI am using VS 2008, Office 2007, and Win7 Home Premium on my system.I have a simple application which should be a breeze to build. All I am attempting to do is pull data from an Access database with four small tables into a data grid on a windows project. Should be simple, set up the data connection, choose a datagrid from the table in the data source view, drag it onto the page and done, right?I can't get it to work. It will all work fine until I attempt to run or debug the project. The data will not show up. The data grid does, but I get this error: A first chance exception of type 'System.InvalidOperationException' occurred in System.Data.dll
As I said, the project seems to build fine, but it will not pull the data. After the initial build I get the message that Windows will show this page in Compatibility View. Is it something with Win7 Home Premium, or a setting somewhere?
I'm trying to use DataView.Rowfilter and I'm getting an exception which says "Cannot perform 'Like' operation on System.Int32 and System.String".
Here's the code...
Dim str2 As Double = CDbl(searchSTR)

It gives me "Cannot perform '=' operation on System.Int32 and System.String" error.
