If you want to create a commercial application and sell it, what is the correct way to obtain a copyright or trademark to the program and its functionality (if you can even do that) If I wanted to give to a potential client to demo, I want to cover myself in case it gets in the wrong hands (read "another developer") Is it as simple as saying "Copyright so and so" in the App Settings?

However nothing I try in VB.NET works. I'm pretty sure it has to do with the fact that the com functions are returning variant data types and arrays (specifically GetVolumes). I have tried using string arrays, object arrays, and even wrapping the return value in a VariantWrapper and I always get errors such as "not implemented" or "the parameter is incorrect." If anyone is bored and wants to write some code I'll gladly give it a shot and report back.

View 6 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.

is it possible to make one application send a task to another application and recieve the result from that secondary app?i made a text editor program and i added a scan feature and i made another app that has ocr capabilities.The scanner ability is in my text editor program, the ocr program doesnt scan you have to input an image into it and it will give text result a few seconds later.the prob is alot of times the ocr code uses sooo much memory and crashes when its incorporated with my text editor, but individually each application works fine and doesnt take too much memory. Memory wont be even an issue if the ocr program is standalone so that when it is done decoding image the application can be made to exit. now here is the question, how do i make my text editor send the image to the ocr program and how do i make my ocr program send the text back to my text editor? is it possible? i mean the only way i know off is creating temp files in a certain folder and having a timer on each program that keeps waiting for temp files. That just seems like pretty lame coding to me i was wondering if there's a better way?
View 11 RepliesWhich is the best way to store application and user settings of an application running with multiple instances?My problem is that using the vb's "Application Settings" one instance would overwrite the other one.I want to identify each instance with a number passed via command line argument. I could use this number to identify the appropriate settings of the running instance, but I see in a local INI o XML file a better way to handle that.
View 1 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.

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?
i made an application for serial communication. for this application i need to set delay time. during this delay time i m doing some other task.

View 1 RepliesI have created an shareware application using vb.net visual studio 2008 for windows desktop, and packaged it using innosetup 5.3.8. The problem is when i have installed the application in C:Program FilesApplication and it runs successfully(use trial period of the application), Im also able to install the application once again freshly with the same setup by installing in different directory.eg C:Program FilesApplication new . The application in C:Program FilesApplication new does not have any settings of the already installed one.
Where do i went wrong . Do i need to take care of this in my application(vb.net) or innosetup. How to take care of the already installed path in innosetup or carry the settings of already installed application to newly installed path by upgrading the older one.
I dont want to write any thing in registry because the application does not want any administrative permission requirements.If i install the application in same path it gets updated with the older settings being taken over to this new one and it works fine.
I am looking for a VB.net book that strings me through the entire development process of an application (Prefered: WPF ,LINQ ,ADO).

View 1 RepliesI have designed and published my small created app with WINDOWS FORMS using VB 2010 EXP on Windows 7. I can only install the app on the machine that I used to develop the app.I want to install the app on another computer but I cannot. I usually have error reports.
Example:Unable to install or run this application. This application requires Microsoft Common Language Runtime 4.0.3 to be installed on your computer.
what can I do to be able to install the app on a different computer which does not have .Net and does not have visual basic 2010 installed.
I have recently created an application where a lot of data is loaded into objects when the application starts up, and other data as it is required. For example if the user requests the catalogue page then it will load all the top level category data into objects of type Category. This will then stay there to be used by other users (who will therefore not have to load this data into objects) and can be altered by admin if they happen to login during the same application instance. I know this is not the most efficient solution, as pointed out below, but it works and the page load, at the moment, is not too long. It is very quick if most of the required data is already loaded into objects. It is also tailored to the business' needs - unlike other techniques such as Linq-to-SQL.
