Developing Messaging Framework For Windows Application That Sends Messages To Java Application

Feb 9, 2009

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.

Developing An Application For Use Over Different Versions Of The .NET Framework

Jan 4, 2011

I am developing an application using VB.Net which is a simple executable which is to be run from a network drive of our company servers. Most users can access this executable without issue - others however can open the executable but have no connection to our database (even though when running the executable off a local drive such as C:, the database works no problem).

From some posts I have seen this might be a CAS issue - however our IT department suggest the issue might be down to different version of the .NET Framework being to blame. Firstly, is this the issue? Secondly, how can I develop my application to work with different versions of the .NET Framework? Surely this doesn't mean developing many different executables?

Choosing The Right Control For Developing Windows Application

Dec 24, 2009

I am looking for a contol either listbox or listview to support my requirements. Basically how my application looks is:

[Code]....

Having said these things. I used to program in VC++6, VB6. But using those version now seems not realistic now as I lost touch. But if I have to use the latest 2008 versions, for which I do not have any experience seems scary. So, If you are reading this , and you have got some experience in these fields or using controls that support my requirement, can you please let me know which programming language or IDE and Control should I use to develop this application. PS: the image is made using mspaint and does not represent actual program.

Programming Login - Developing A Windows Application Using Visual Basic 2008 With A SQL Server Database

Feb 26, 2011

Iam developing a Windows application using Visual Basic 2008 with a SQL Server database. Throughout the program I give the user as many options as possible and have no problem with either the database or the windows forms. The program does not initially require a Login and I want toprovide the User with the opportunity to add a Login to the system. The default Login form is perfectly satisfactory.

The problem is that I can't figure out how to program the change sothat the Login from isopens the program rather then th form designated as the StartUp form. this forum I am able to prgrammatically change the form but I can't figure out how to make the requirement a permanent factor. I tried using a Constant, but if the User wants to change, you can't change the constant. Its an apparantly simple yes/no situation but if I set a varable to yes and then change it to no the next time the program runs, the change will be lost.

IDE :: Windows Application Framework Properties?

Feb 18, 2009

For a reason I cannot explain, I now get compiler errors from the Application Designer whenever I enable the application framework in the VB.net IDE.  I do not find much on this issue, except Scott Hanselman's admonition not to use this feature.  I have mature projects in which this feature was enabled, but now even they will not compile.As this only began a few days ago, I have been trying various approaches to resolving the problem, up to and including removing VS2005 and reinstalling it, along with the framework, SDK, and all updates.  No dice.  The errors are below.This condition will occur even if I enable the feature in a new project.Does anyone have some thoughts and the cause and resolution of this problem?I probably should mention that I was using both VS2005 and VS2008 on this computer.  I had been experimenting with 2008 for several weeks without incident.

TCP Messaging -application Call Center - Team Leaders Can Send A Message To Individuals Whilst They Are On The Phone

Aug 7, 2009

Im currently writing an application for our call center to use and would like it to have messaging functionality so that team leaders can send a message to the individuals whilst they are on the phone.

I have used a couple of tutorials around the web, but they differ to what i actually require. They all seem based around the whole "client must connect first" thing, is this really necessary? I just need each user to be a "server" constanly listening to any message recieve on a specific port, and display it in a popup when one is.

At the moment the code i have sort of works, but its a bit flakey and doesnt handle the initial connection/final disconnect very well.

Client program (team leaders console):

Form:

Imports System.Net
Imports System.Net.Sockets

Application That Has Multiple Front Ends Developed Using Windows Forms / WPF / ASP / Compact Framework Mobile Forms

Apr 9, 2010

I have the requirement to create an application that has multiple front ends developed using Windows Forms, WPF, ASP and Compact Framework Mobile Forms.I would like to be able to create a series of obejct representing the business logic and have this logic accessible from the various front ends available. My first thought was to use remoting as I'd like to be able to pass the business objects back and forth between client and server but the compact framework doesn't support remoting and also transferring a full framework business object to a compact framework business object doesn't seem possible.My next thought was to use web services but again the passing of business objects seems to be very hard to accomplish. Without doing this I would have to create individual web methods for each business operation.

Finally my next option is to use sockets and write the whole client/server logic within some classes and expose them to the UI/Business layer. My only problem with this is it is not scaleable should the number of clients increase dramatically whereas using remoting or web services I can host the solution via ASP.Net.Does anybody have an ideas on the best way forward for this or even have any input on how they would write an application that required a windows form, wpf, asp website and mobile device GUI all of which want to use the same business logic?

I tried running my application again and now the xp visual style has gone and it looks terrible, is there anyway to get the application framework back on again or do I have to start a new project and copy and past all my code into the new project.

PostMessage Interrupts - F12 => Application Unhides And Restores Window - Sends WM_RBUTTONUP (right Mouse Button Release)

Jul 12, 2010

My application watches two buttons:

1. F11 => my application minimizes and hides another window (windowHandle is its handle), then sends there WM_RBUTTONDOWN (right mouse button click&hold).

2. F12 => my application unhides and restores that window, then sends WM_RBUTTONUP (right mouse button release).

The problem is when I press F11, and then click somewhere (so windowHandle loses focus), the right mouse button releases automatically, but I want it could be released only after I press F12. Here is part of my

Public Sub Tick()
Dim windowHandle As IntPtr = FindWindow(vbNullString, "App")
If GetAsyncKeyState(Keys.F11) Then

VS 2008 Language - Developing An Application That Uses A Sql Server Database

Apr 13, 2009

i 'm develloping an application that uses a sql server database, in my computer where i'm programming i installed the sql server in the same language of the OS, in the tests of the application everything worked fine. Biut after migrating the db to the main server, the values went crazy.. After some research and tests, i saw that the language of the sql server was in english and that was the problem.

My language settings says that the decimal separator is "," and the agrupment digit it's ".", and the sql server works in the other way "." is the decimal separator and the "," it's the agrupment digit. In my code i was using the CDEC to pass the values to the DB, to solve this i removed the cdec and send the parameter as a string (So if i send 2,33 to DB with CDEC i get 233 if i send the 2,33 string i get 2.33). This works for now, but i don't know if in the future i'll have problems...
