View 1 RepliesI would like to create a Windows Service that uses settings that are set from a GUI application, such as a Windows Forms application. I have seen this type of feature in programs that allow you to set options like "Run as service" within a Forms application, surely there must be a way. I have only came up with a rather primitive way of going about it, which is, to have a GUI create a text file with a predefined format that the Windows Service recognizes and at a predefined directory. And then have the Windows Service just read from that predefined directory with a predefined file name. But, this seems rather cumbersome.
View 2 RepliesI've created a windows service application. i've also created a windows forms application that can automatically control the service ie. start, stop, install,uninstall, timer property change...... however all this is only one sided, ie i'm passing information from WinApp to WinService.
What i wanna know are ways to get the service to pass variables values from the service to the Application.....

View 2 RepliesSince I am answering 2 threads about communication between 2 applications and that I talk about memoryMapFile in these posts I am posting this for those that can be interested Even if the MemoryMapFile exist since a long time in the native code world, it is new with the framwork4 in managed code.I would start by saying that if you look at the examples showed in the documentation, the control is done using Mutex ... It is what you DON'T want to do The right way is to use window message to automate The example here is: 2 applications, one with 2 buttons and a label.
Button1 ask the second application to start Notepad and Button2 ask the second application to stop it When the second application has executed the command asked by the first application, it send back a string that the first application show in the label The buttons are only enabled when both application have show that they are ready for the communication

View 2 RepliesI am starting a new project in VB, a card game modelled to be similar to a real card game.
I have the majority of the program planned out and have even started coding parts of it; my problem comes with the networking.This is a real-time card game (not turn-based) and I want to be able to play with real people (family mostly, so over LAN is what I'm after).
I have tried searching for code samples but I everything I have found seems more complicated than I feel is required for the task, introducing a lot of new concepts and not explaining them.
What I'm after is a simple way to exchange the information in real-time, I don't care so much for efficiency (at the moment) just ease of use - though if I need to wade through a heap of documentation I will. A perfect answer would tell me what the names of some of the controls/methods that would be appropriate are, even if it just re-affirms a bit of the complexity, you do not have to detail anything if you don't want to I just feel a bit at loss as to what exactly it is I am looking for!

WRN: Assembly binding logging is turned OFF.To enable assembly bind failure logging, set the registry value [HKLMSoftwareMicrosoftFusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.To turn this feature off, remove the registry value [HKLMSoftwareMicrosoftFusion!EnableLog].
I guess this is a reference issue, but I have added references to WMP libraries (axinterop.wmplib.dll and interop.wmplib.dll). The WMP works on the XP machine, but not when called from my application.I have searched the web now for 5 days and changed references, and reinstalled the media player on the XP machine, but nothing works.

I am in the process of developing a messaging framework for a windows application that sends messages to a java application. To be precise when the win app wants to send a message it simply drops the message in a common database table which will be picked up by the java app. The windows application is deployed across 10 application servers (10 instances) over citrix for load balancing.Each instance of the application is capable of sending a message to the java application and each of these messages should have a unique id. From my end I need to make sure every message generated has to carry a unique id so that they can be identified when necessary. All the messages can be cleared every day or two.i am not quite sure about a best method of achieving this. Initially I wanted to create a static method that serves the next available id (incrementing the last id by 1). But this approach willn't guarantee unique number as the application starts only when at least one user is logged on. For e.g .On one server the app starts when a user logs in, he then sends a message and then the application stops when that user logs off. So when a next request for the app comes to that server a new instance will be started.
View 3 RepliesI currently have a simple crystal reports application which generates a crystal report and in the built in viewer provided by VS2005. There is a drop down where you can select options to change the criteria of the report. I wish to convert this app to a windows executable which will take all those select options and generates pdfs based on the crystal report. the executable will be triggered by windows task scheduler...or maybe command line app?
Obviously this will be somewhat of a re-write. What would be the best way to start this as? a crystal report application or a windows application.
I have a windows forms application written in VB.NET which scrapes information from serveral web pages (who doesn't right)? Anyway, I am having problem with one particular site where partway through the page navigation my application hangs. When I press pause (or break) in the debugger, it stops on a call to System.Windows.Forms.Application.DoEvents.
Resuming execution shows that it really is stuck on this line (it does not reach the next line of code). It also hangs about the same point each time I run it (at least its consistent). Since System.Windows.Forms.Application.DoEvents yields to other threads on the same processor and then resumes execution of the current thread, I think the problem is that some other thread is not behaving well (not returning from some event handling code). I thought Windows 7 was pre-emptive, which makes me
doubt that theory but I really don't know.
[Code]...
The program scrapes somewhere between 12 and 14 pages before it gets stuck on the call to DoEvents. Does anyone have a clue why this would happen? Why would any call to DoEvents hang?
