Which is the best way (fast and robust) that .net framework (3.0/3.5) provide for interchange information (for example: dataset packages) between two independent vb.net applications?

Boss assign me a project: Create a vb.net program for EDI (electronic data interchange). I have no any idea how to start.
View 3 RepliesI wanted to know how can two independent .NET application can exchange data. Something like DDE which was there in older versions.My purpose is to have an upgrade application (which is a seperate .net program) and my main application. Now I wanted to know that when my upgrade app runs it should be able to confirm that my main application is not running. How can I achieve this ? I know thru process name I can find out if my main program is running or not but thats risky if there is another program with the same name.Thus I wanted a way whereby my independant .net program (upgrade app) is able to determine if my another application (main app) is running or not.

I have 2 applications which we can call for example Client/Server.
I would like to exchange data between these applications but basically don't know which is the best route.

I have two VB projects in one VS2010 solution. The first program brings in about 60 integers every few seconds from my PC's serial port. The second program, published via Click-Once and running on my customer's PC, needs to see that new data every two to five seconds.
Is there a simple and reliable way to accomplish this, staying with VB? WCF is way over my head.

I would like to know if it was possible to share data between several assemblies using the same DLL.
I'm not looking for a workaround using memory or disk files of some kind of pipes to do the job I just want to know if and how:
1 - I can run an App. referring to a DLL which contains a given shared data structure.
2 - Run another App. referring to the same DLL that will use the already loaded DLL and data instead of creating a new base instance.
I want to build a main application that make the autentication process and store the loged user... Then use X and Y applications to ask the current user and depends of the user will have full access partial or none access to the app. In future a Z application could be created and will ask for the current user also. XYZ apps are lauched from Main app, when Main app is closed the others are closed and User ID data is cleared. Of course the main app will handle the log on/log off process.
- Store User ID in a Database is toooooo much for just do this
- Save the User ID in a local file like XML is a security problem
I tried to do a WCF Service but i think its not possible to send data and store in it.The other point is who to handle the instantation issue... each program will access to the same static data not create independent.
I have started making applications that retrieve data from sql databases.
I write the database with Sql management studio then apply that database to my applicaton.
My question is, how can I make my applications more secure against hackers. Some applications store user names and passwords and personal information / finantial information and so on.
I have 5 websites running on same server and I have some sql tables that I access frequently. that was time consuming and by defining them shared I pumped them in memory. So my application is accessing those static data tables from memory quite efficiently.
But I realized I did a mistake and I occupied my memory unnecessarily while I keep same tables 5 times for each web application. Now I need to find the best way to share that table only 1 time. my options are;
1) using a local database - sql CE. my original sql database is on other server. so it makes the access slower but I can add a sql CE database(to be honest I never used it and dont know if it gives me anything) to access only these tables while they have static rows.
2) I read over forums that making a WCF using tcp binding. not sure if it will give me any advantage.
3) windows service: is it faster than wcf? programming is defiantly faster as i have experience with winservice but nor sure about performance.
When I try adding a new data source to my project I get a prompt saying "The connection you selected uses a local data file that is not part of the current project. Would you like to copy the file to your project and modify the connection?"This sounds rather obscure to me, as I'm new to VB.NET and programming non-script apps in general. The data source in this case is a .sdf SQL CE file.
Question 1: If I say that I want to copy the database to the project, what will happen after I compile the app, where the database will be? (how will I edit it from another app?)
Question 2: If I do not include it, how the data source will still keep linked? Can I link using filesystem enviroiment variables like %ProgramFiles%MyAppDir?
Question 3: Can I just tell it to use a read-only (Just needs to read it) data source on the web, like on an FTP?
I am having issues retrieving a class serialized in another application. If I put the code all in one application the set and get both work. If I separate the code into two applications the retrieval fails. Any thoughts on how to set the object to the clipboard in one app and get it back in a second one? [code]
View 3 RepliesI have some friends who are 'old-school' VB6 database developers and I was telling them about .NET and its features, specifically ADO.NET. In our conversation, they brought up the following reasons why they would rather stick with ADO than move to ADO.NET: The Dataset is disconnected (What if power fails?)
The same amount of code still has to be written The new options of Dataset, BindingSource and TableAdapter seem confusing the same code is written programatically access the Database, all that changes is how that command is laid out. Why ADO.NET is 'better' than ADO with regards to data access when it comes to Windows Forms applications. What does ADO.NET provide that ADO does not? What does it do better than ADO? I'd like examples that do not involve LINQ.
I'm having difficulty figuring out how to run different programs with my VB program. Using Excel and other MS office programs is easy enough since I just add in the relevant COMs, but I can't for the life of me find out how to run other programs. I promise I spent many hours searching before bothering you kind folks here! I'd think this is a common issue so maybe I haven't been searching for the right thing.how to write code that will control and read data from applications.I know you can do "Process.Start" to open any application, and it looks like there are ways to determine the controls available on an open application, but I can't figure out how to do it. Is this possible? Or do I have to import a .dll file for every program I want to control? Or are both possible?
View 12 RepliesI would like to make a web browser for my own use with various customizations. However, in VB6 the various web related control like winsock, inet fetch only html. Using webbrowser control is not the answer because it uses the same settings as windows IE. What I'd like to know is a control somewhat like the webbrowser but independent of windows IE setting. So that the changes made in IE wont effect my web browser. And also the webbrowser control does not have features such as blocking a specific image/CSS according to URL etc.
