Unable To Execute SQL Command In Windows Service
Jun 30, 2011
I'm working on creating a windows service that will send emails to a customer when they are within a month of having their submission expire. I'm using vb.net in Visual Studios 2008
Because it's a windows service it's very difficult to debug. Trying to narrow down my error I created a "sendDebugEmail" method that sends me an email if it gets to a certain line. The emails never make it past "dr = cmd.ExecuteReader()"
I'm wondering what I am doing wrong. My SQL statement should work fine. I've tested it in my SQL server database.
I've created a dummy_database that I just made in sql server as well. I added an INSERT sql statement for the dummy table i have in there just to see if i could actually access a database. All the table takes in is the line number and time it was sent. When I run my windows service that database updates just fine.[code]...

I've been trying off and on for a week now to get this to work but no luck. I have completely stripped down my vb.net 2008 windows service to just create a vbs file and launch it using a process.I'm dying here. The vbs file creates and is valid. I can execute it manually, the windows service just won't run it!! I'm on a windows 7 machine and the process is compiled and installed as a 32 bit process. It is also installed as local system.
After the process tries to execute, I created a text file and it did so successfully. So, I know that the service isn't crashing out.[code]....

I have a .net Windows Service developed in VB.net. I have a settings file in the root directory called Connections.XML and I am setting the basedirectory [code]...
When I schedule the service this is working absolutely fine in my Windows XP machine. But when I installed the same service in our development server (Windows 2003 64 bit Server) for some reason it is not able to locate this file.

I cannot run Windows Services , I am getting error message "Cannot start Service from the command line or a debugger. A Windows Services must first be installed (using Installutil.exe) and then started with the ServerExplorer, Windows Services administrative tool or the NET START Command."
I have run the InstalluTil.exe and open the Visual Studio 2005 command prompt and run below command but still not working.
InstallUtil " D:\Khwathie\MyNewService\MyServ\MyServ\bin\Debug\MyService.exe".

I have a simple question that I can not figure out.I have a service (service.exe) that is running as SYSTEM.I want to be able to send this service command line arguments. How would I do this? I am not able to just service.exe /arg because the service is running as SYSTEM and I am logged in as an admin. Is there way?

I have a Windows Service that needs to start other processes under a user context other than that used by the service. I've seen other posts related to this but have seen no resolutionI've tried many things and have been unsuccessful in starting the process from a Windows Service when a username, password is supplied. orking as it's a requirement of our system to do this and it worked fine until recently and only fails on Vista and Windows 7 (works on XP).
The following code is used to start the process.
Dim P As New Process
P.StartInfo.Domain = Domain

I wrote a VB.NET Windows Service, which works fine. I have only one issue with it. I want the service to execute on the half hour and top of the hour marks (e.g. 9:00, 9:30, 10:00, 10:30, 11:00, etc etc etc). I am using the following code:
Protected Overrides Sub OnStart(ByVal args() As String)
' Add code here to start your service. This method should set things
' in motion so your service can do its work.
[CODE]...
This code works, however, if the service starts at, say, 10:15, then it executes at 10:15, 10:45, 11:15, 11:45. How do I make it so it always executes on the 30 minute and top of the hour marks?

i have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:
Warning: Type library exporter encountered a type that derives from a
generic class and is not marked as
[ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be
exposed for such types. Consider marking the type with
[ClassInterface(ClassInterfaceType.None)] and exposing an explicit
interface as the default interface to COM using the
ComDefaultInterface attribute.
It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.

Its something in the syntax for the command.
They provide this example in VB:
Dim MtbApp As New mtb.Application
Dim MtbProj As mtb.Project
Dim MtbCom As mtb.Command
[Code]....
what I'm expecting should happen is Minitab should open, and the command should execute. However, whats happening is that two instances of Minitab are being opened and neither are showing user interface, I have to find them in processes.

I have an executable that I normally execute from cmd window. Now I want to write a vb program that does it, captures the output that the program would normally show on commandwindow and does some further stuff with it. Shell would be the starting point, I guess.

I am trying to execute a shell command with vb.net that includes variable from the vb.net code.I have experience with batch, and Unix scripting. I had to modify the contents of the code as it is confidential to me at the moment.Example of my problem:
Dim Variable1 As String = "Location_to_.exe"
Dim Location As String = "UNC_Path_Goes_Here"
Dim Options As String = "/Options go here"
Shell("cmd.exe", /C Variable1, Location, Options) This is something that must be run from CMD.exe and I am trying to do it this way to make it as dynamic as possible.

Lets just say we have this as Command1 Dim Command1 = "whoami.exe >> C:Hello.Txt" The program will read a list of users from a text file and then perform the action on each of them. If the user does not exist, or they are part of a password protected computer, I would like to see that in my printout. I have this but am Unsure how to write the If Then Statement (If that is the ebst route to take)
