View 1 RepliesQuestion: I created an ASP.NET web application. Now it originally was meant for deployment on a webserver.That is working, so, so far so good.My question now is: Is it possible to deploy it as a desktop-application, too? That is to say the installer installs some kind of server, plus the web application, configures the server to run this application on a localhost URL, and then creates a link in the start menu/desktop, where it opens that url (website, the application) on localhost in a web browser?
I think it should be possible, though the server wouldn't be IIS, because this is a windows component which can't be separately installed. Is there anything like this already out there The nonplusultra would be that it only starts the server when you click on the shortcut.
when i m instal my application to other computer its Require Dotnefx3.5 and Windows instaler its require internet to download missing componant to install Before running my application so how to install my application with these other component (who need my application)
View 24 RepliesI am working on some custom components that I would like to sell with a form of licensing,
Is there a way to make a component exit a application?
Meaning, if the license key is no good, i want it to pop up a msg box, then throw a quit.
I figure I can always run a 'Throw New Exception("Invalid Key")', but that won't cause the program to stop since it's behind the scenes.
I realize that if i add checks, then i can say 'If CodeIsInvalid then don't process the process'.

I have this code and I hope that this is correct. I build a dll component from the class file that contains this code and I am trying to use it as a reference in windows forms application. I have allready made this forms application and added the ddl to the reference but I do not know how to use it in there. I would like to activate (insert value 1) inputA & inputB using checkbox and that the outputQ is displayed in textbox (1 or 0). Do I have to use a vb interface to do this? And how can I use this code as dll component in the forms application?
I'm working on a VB.NET application for disabled people which uses the WebBrowser control to capture the HTML content from an webpage (just to present, after some code treatment, in a textbox) and trying to solve the following three problems:
1) I'm using the WebBrowser control just to load a web page, but some pages provide a refresh after some minutes. Is it possible to avoid/disable the WebBrowser refresh (important: I need to keep the WebBrowser instance alive, so I can simply dispose it) or I'll have to rewrite my application to use WebClient control instead? (solution that will be provide much more work in my case).
2) The DocumentCompleted event, that takes the HTML content and shows in the textbox, is called several times for some pages (like www.uol.com.br) and obviously beginning to execute the code on my sub method several times too. A friends of mine tell me that maybe it can be solved "setting the WebBrowser for HTTP 1.0 to avoid the load from Ajax content". Is there anyone who knows how to do it or simply knows a way/event more precise?
3) Is it possible to take the HTML content and convert the charset "on the fly"? If not, anyone knows an URL with a sample code?
I have created a small multithreaded application using VB.NET. There is no problem when the user manually runs this application. A problem exists when I added this application on startup. It hangs after I rebooted the system. The application is still running its thread but I can't see its GUI because its frozen. If I kill it on task manager and started again, the application works fine. What could be the possible reason/s why this application hangs when added on startup?
Imports System.Threading
Public Class USBLock
Public Event Lock()
[Code]....
or just a thought on this subject: the reason why the program hangs on startup is because the application is loaded while the .net framework service has not yet started.
come years ago I bought an activex component to read some basic smartcard data. I created a simple form application and it has worked fine ever since. However, instate of a form application I now want to create a console application for the same purpose (the forms are unrequired and it just takes too long with multiple smartcards).
But I have been working on this for days now and somehow can't seem to get my events working. When I use 1 event, everything works fine, but as soon as I add my second event I get this error:
Unhandled Exception: System.Runtime.InteropServices.COMException (0x80040202): E
xception from HRESULT: 0x80040202
at System.Runtime.InteropServices.ComTypes.IConnectionPoint.Advise(Object pUn
kSink, Int32& pdwCookie)

I fixed it, I the Event Handler got deleted somehow and that was causing the problem.

I am creating a windows application setup project using Visual studio 2008 setup project. This setup will have following steps[code]...
View 1 RepliesI'm running into this one very specific issue:
- I have a VB.Net 2005 Project for which I've created a Setup Project.
- In my Setup Project, I've added a shortcut on my Start Menu, that points to my Application.
- After deploying it, all works great.
- One of my users chooses to *copy* the shortcut from the Start Menu into their Desktop.
- I then create an upgrade for this Application. Again, the deployment works great. They can start my application from the Start menu.
- They double-click on their icon in the Desktop and they get a popup: Title of the message box: Problem with Shortcut Description of the message box: (X) The parameter is incorrect.
The shortcut's Target, is blank ( which I believe is the problem ).I'd love to be able to specify an actual [TARGETDIR]myApp.exe type of string as the shortcut's target in my Setup Project, but I can't do this.Instead I have to point it via UI, to my Target Application ( which I'm assuming is resolved at install-time ). The problem with this is that it appears that the shortcuts get re-evaluated every time you re-install / upgrade the application. Since my previous version is technically not installed anymore, my shortcut gets invalidaded, even though the target path is still the same and I haven't changed my executable's file name.

View 1 RepliesI am using a 3rd party dll in an application and the installer does not register the component irrespective of any settings in the install package.It will register manually though using regsrv32 after installation.My question is how can I use the System.

I have a program that adds controls on the fly to an auto-scroll panel. When the panel is scrolled (viewing the bottom of the panel for example) and a control is added, it looks like it is added assuming the top left corner of the panel is still at 0,0 when in fact it may be 0,500.

View 11 RepliesI am working on a realtime application where the data is addded to a List(of T) all the time. MB per minute
Elements older than X minutes shall be removed from the beginning of the list to free memory.
As far as i can understand will there be an internal (slow) redim when i add each element after i have reach the number defined with the Capasity metod. (I set that quite big from the start, but the data speed is unpredictable so it can be exceed)
What happens each time i remove and element from the beginning of the list , seems like it takes a lot of time, ? new redim ?
What is the most CPU fficient way of removing 1 or many elements from the beginning of such a list?
