Can I pass parameters back and forth between a Windows Service and .NET program? For ex: I want to pass a compressed/encrypted byte paramater to the Windows Service, who then decompress/decrypt it and return back the decompressed/decrypted bytes.
View 1 Repliesim not 100% sure this is the right place for this, but thought I'd give it a shot.I created a windows service, and it accepts startup parameters to set the connection string for my database connection. (-L for live, -D for dev, -S for stage etc.)[code]I installed the service using installutil (I already tried using sc.exe) and I can't specify startup parameters.So if I go into Services and go into my service properties and manually type -D into the Startup Parameters box and hit start, I get -D as my parameter, life is good. But the parameter won't save in the startup parameters box, it just reverts to a blank box whenever I close the properties page.[code]
View 1 RepliesI 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.
It is possible to create windows service using windows form control in vb.net.If yes then please give me the url or links.
View 1 RepliesJust started VB programming this week and have found a wealth of information about what I'm trying to do. Problem is, some of it is more complete than others.Here's what I'm trying to do:In Form1 (my main form), I want to instantiate a class that contains a couple of properties (speed setpoint and position setpoint). When I click a button, I want to pass this data to Form2 and populate two textboxes on Form2 with the properties of this object. I want to manipulate the property values on Form2 and click an OK button which closes the dialog and returns the manipulated data, updating the property values of the object. Here's the algorithm I'm following:1) On Form1, instantiate the class2) On Form1's "Pass Data" button click event handler, instantiate a Form2 object and invoke the ShowDialog method, passing the object as a parameter.
3) On Form2, overload the ShowDialog method to accept the object as a parameter and modify the method so that it returns the manipulated class data.4) On Form2, in the ShowDialog method, populate the textboxes with the class data that was passed in.Here's where I get stuck. If I press the OK button on Form2 (DialogResult.OK), it returns me to Form1, but what hook do I have in Form1 to receive the manipulated class data that the ShowDialog method is returning?Here's an example of what I'm thinking about:
Code:
Public Class Form1
Dim clsController1 As New MotionController

I'm sure it's probably a very elementary question, but every explanation I've found seems to be incomplete.
How do i run program as windows service or by windows service.
For example :
run notpad.exe by windows service and user cant terminate it.
I have a program which i want to invoke from windows service.
[Code]....
The same code works fine if i write in a console application, but from windows service it wont run, i see the psftp is being started in the task manager but it wont do anything.
It works on my own computer where I have visual studio installed. I install the exe file with installutil and the service works fine. But when I install it on another computer where only the framework is present, I still can install it with installutil BUT I can't start it. I get something along this Could not start the Search service on Local computer. Error 1053: The service did not respond to the start or control request in a timely fashion.[code]...
View 2 RepliesI created a new Windows Service and a stand alone set up program for it. To the solution I added a set up program project and included both programs as outlined in [url]... However, when I run the Setup program, I do not see the my new service in the services window after the set up program completes. Is there additional work that needs to be done to have the program install the windows service correctly or do I need to include the [url]... program and a batch file to get it installed?

View 1 Repliesi 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.
What i want to happen is for the dictionary keys and items to be overwritten each time it is executed, as the data needs to be up to date.

View 5 RepliesI'd like to pass a parameter on the startup of an application, and use it in my code.
Such as passing parameters in C# using the (String []args), then referring to them by args[i] for some i.
For example if I have a function call like below
Function callingMe()
Exit Function
And my Function call is like below
SomeObj.callingMe('1','2','3','4','5') // Variable number of arguments
Inside callingMe() function, I want to know arguments passed i.e 1,2,3,4,5 and the Object i.e SomeObj in above case.
I've created an exe that is a ticket management system for in-house debugging, etc... It uses the same database that is accessible via MSAccess. In order to create a seamless work environment, one of the supervisors wants employees to be able to see data from the tables the exe uses without actually opening the exe and looking up the record. That's no problem since it's all the same db, but they also want to be able to open that ticket with the click of a button...instead of opening the exe and doing the search themselves, they want to just *click* and have the appropriate ticket open in front of them. I have no clue where to even start to do this....

View 4 RepliesI have a bunch of methods that do some formatting on data that is contained in a structure. I'm passing the structure to the methods as a parameter. The problem is that the same structure is returned from 2 different webservices depending on the program flow (I did not create these services and cannot change them). So at one point I would be passing WebService1.Service.MyStruct and later I might have to pass WebService2.Service2.MyStruct.
Is there a way I can write only one method to handle both type of parameter? The struct is the same and only differs by namespace. I can overload the methods but I was wondering if there was another way to do this with reflection or something along those lines.
Just kind of curious about something: why does VS (vb and C#) default params to pass-by-value?I almost never need or want to pass anything by value. Maybe this is some reflection on the way I code. I would never manipulate a value type param directly; i would just return the new value from a private variable... and I just don't see the need to do the background work all the time to add copies of everything to the stack. Why wouldn't I just about always want to pass-by-ref?

This code calls a store procedure that takes input parameters. With this code I'm confused as to how the parameters are passed to the stored procedure. The parameters are first stored into 2 string variables (strCategoryName & strOrderYear). They are then copied/moved to an sql parameter prm.value. But the stored is stored in an sqlcommand (cmd ). I can't understand how the stored procedures knows what the parameter values are.
