I have a small service which right now I just want to test by printing some string that is passed in and stored in a class.
Problem is everything works fine, service even starts fine as long as I don't call PrintDocument's Print function.
The moment I do that, the service never starts and I get Error 1053:Service didn't respond, etc error.
Since the coming of Windows7 at our office we have sometimes the issue that the print spool is crashing.Users don't have admin rights to restart the service so that leaves them only at restarting their computer as solution.Which costs alot of time... As we cannot find a final solution to this problem I've begin to write a small tool so they can restart it..I've only hard code a local admin account in the source for this operate for them..

View 3 RepliesWe have service developed in Visul Basic .NET. This service utilizes some COM objects provided by SAP to access SAP database. This has been working fine till yesterday. On this Sunday, we upgraded the SAP system, and subsequently all other programs were also re-builded using the new DLL files (for the COM object). We tried doing the same for the service also. But it is not starting now. When started, it shows a message saying service terminated unexpectedly. This is probably due to the fact that it is not able to load the requisite DLL file.

View 12 RepliesAm trying the following to start a windows service
Try
Dim myController As New ServiceController("FCR GEFU Server 1", "10.1.1.208")
myController.Start()
TextBox1.Text = "Service Started"
Catch ex As Exception
TextBox1.Text = ex.Message

Am getting the following error:Cannot open Service Control Manager on computer '10.1.1.208'. This operation might require other privileges.How should I provide the log in credentials for the remote PC !?
My app (which runs ok as a standard user) requires updates to be installed, but I don't want to have to input the administrator username/password each time nor do I want to increase user privileges to administrator.
I have a windows service which handles the downloading of updates etc (running as Local System) but the start command needs to come from the main app (running as a standard user). This is not permitted and I get Access Denied.
I understand why this is happening but is there an alternative way to achieve this? I want to handle program updates as the standard user without using ClickOnce or installing to a non Program Files folder.
I've created a Windows Service and installed it via InstallUtil so I can test it out.The installation goes seamlessly, but it will not start from some reason. When I attempt to start it, I get an "Access Denied" error and that's it.
I haven't been able to find any information via the normal channels.I first thought to give the service admin rights, but that didn't work either.
I am trying to create a windows service that sits in the background waiting for programs to be started. When the programs start I want to be able to check a unique bit of information for each program (I believe GUIDs may provide this) to see what the program is. If the program is not allowed, I aim to provide a warning to the user and possibly close the program. The aim of the application is to identify when users are attempting to install additional software on to the computer so simply monitoring for a certain executable wouldn't work as msiexec is called for all MSI's and as I only want to stop blacklisted programs...this wouldn't work.
View 4 RepliesI am developing a Windows Service in VB2008 and am in the testing stage. What I have noticed is that if I Pause it while it is busy doing something and then resume it, the process generates an error. While I am debugging this I wanted to determine exactly what the difference is between Pausing/Resuming and Stopping/Starting a service.I searched, but most results simply told me how to Stop/Start/Pause and Resume a service, a hurdle that I jumped over many years ago. Does any one know of any resources that go into detail what happens when a service is stopped vs when it is paused?From some experimentation, it seems that if I do not place any code in the OnPause and OnContinue events the Pause/Resume commands have no effect.
View 1 RepliesI have a VB2008 application which can control a windows service i.e. start, stop, pause etc. This runs ok on a Windows XP machine but not on a Win 7 machine (message is - Service error cannot open <service name> service on computer '.') ( if I stop the UAC then it runs ok ). It seems to be a rights issue,
View 3 RepliesThis is a bit of unusual problem that I'm experiencing, but recently one of the users of a production application started reporting errors in the system. These were traced to a 503 Service Unavailable error when making a call to a web service used by the application.
Now here's the odd part, only the one user is affected by this issue. Other users of the application have not reported any errors. When the user logged on to a different machine that worked for another user, they still received the error.
I have a service that receives commands over the network and interacts with the database. At the time that I add a transaction I would like to print some sort of receipt ticket out to an epson tmt88iv. I would like the service to do this rather than have to maintain the printer on several tablets....Is this possible?

View 14 Repliesit was regarding in vb.net text operations, i want to replace the text by finding some particular text.but the problem arises when the starting and the at the end delimiter of the string is something same every-time but middle thing keeps on changing so how can i work out with that?? str = Replace(str, "abcdparameter = xyz123;", "abcdarameter = my defined parameter;")
i tried to learn some regular expressions but i am not able to get that.the xyz 123 is same every-time....and also there is one delimiter at the end of the parameter string so anyhow you can select the whole line and replace it.
I have a simple text file containing a list of names that I wish to sort. I was hoping for something simple like:
System.IO.File.ReadAllText("MyFile.txt")
System.IO.File.Sort("MyFile.txt")
System.IO.File.WriteAllText("MyFile.txt")
or something like that. Didn't want to actually write a bubblesort/quicksort routine myself.
I would imagine the routine would just rewrite the final file or would I have to make a new file and copy the contents back to the original?
How do I start writing a program that has 6 text boxes. A person would enter a member number if they have one, number of movies rented at $1.80 a piece. A Text box should then display Total Rental Price, and if a member number was entered, a 10% discount is given (the total of the discount shows up in another text box) and after there discount is applied the Amount Due is displayed in yet another Text Box.
My boxes are named:
memberNumberBox
moviesRentedBox
rentalPriceBox = $1.80
totalPriceBox
discountBox
amountDueBox
This is all supposed to happed when the customer clicks on a calculation button named: Button1
This is what I have so far, but I don't even know if this is correct, as I am getting 1 error relating to a name not being declared. Please help and clue me in to where to start!
