View 4 RepliesI 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.

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.

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.

View 3 RepliesI 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?

View 4 Replieshow to develop unicode application in vb.net and sql server 2008 ?how to start develop and what are the things i have to consider to develop effective unicode application ?. this application should support japanees and english language based on user selection.i took steps but i don't know it is correct.
1. i created tables in sql server with fields, for strings - NVARCHAR, for integer INT, for datetime DATETIME,for numeric NUMERIC.
2. i created another setting-table to have all screens name,label names ( for labels and grid column headers ) and corresponding japanees display names and another column for english display text.
so i'm just going to fetch Japaness/english display names from setting-table on form load and change the labels.Are these correct ? or anyother way to do unicode application effectively ?
i've developed vb.net window application in english language.. its working fine but it has to support japanees language also.. Displaying text, input text every thing should be japanees... so user can select english or japanees, based on that label, input control language has to change..

I'm about to start a new project and want some advice on how to implement.I need a web application which contains a booking module for reserving timeslots, and a time management module which will enable employees to clock in / clock out.
If I am writing an update to the time managment module, I don't want to disrupt the booking engine availability by releasing a new solution containing both modules.to make things more difficult, there is some shared functionality like common users, roles and security.Here's a suggestion I've gotten, which sounds a bit cruddy, but may be functional.Write a 'container' web application which consists of basically a frame, and authentication / security features. This then has links which, will load the 2 independantly built and released web applications into the frame.I can see that say, if I wanted to update the time management module,

View 4 Repliesi '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...
