Application :: Display A Message To The User Whilst The Application Is Starting Up?
Nov 4, 2010
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.

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

I have an application which uses hotkeys which are to be defined by the user. It is a combination of 2 keys, either CTRL, ALT, SHIFT as one hotkey and the F* Function keys as the other (e.g. CTRL + F1, ALT + F2 or SHIFT + F8) As stated these are then chosen by the user before a global keyhook is put in place to listen for them and trigger an event. In my app I have all my function keys as follows:
Public Const VK_F1 = &H70
Public Const VK_F2 = &H71
Public Const VK_F3 = &H72

I am in need of a small application, that will allways be topmost and will send keystrokes to the last active application (typically notepad or an explorer window). My problem is retrieving the current active form (or application), when my application is started up. Every search seems to return old and rather complex solutions using Win32 library functions, but I was kinda hoping, that .Net allowed for a neater and more simple solution.I need a code example or link on how to retrieve the currently active application window from another application just starting up.

So im trying to allow the user to send a message to an application on a server telling it to do different things. So i build the client and the server side applications and tested them on my computer and another computer here. Everything worked great, just like i wanted it to.
When I moved the server application to the actual server and tried connection via the internet, it did not work. I got the error message: An error has occured : A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond IPADDRESS:PORT
Well then I realized chances are a VPN connection to my server and using my servers name instead of my servers IPADDRESS would fix this problem, which it did.
I dont want to require the user to have to create a VPN connection, i dont really care reather they use the IPaddress or not, although if theres a fix for that too it would be great. Heres my code: (I have marked where the error occured)
''Client

I have recently started playing with sockets, so now i have set up an instant messaging app. it works like it's supposed to however, theres a slight problem. short of arranging for both parties to come online via email or something there's no way for the other person to know that someones waiting for them. So i'm basically looking for a way to send a pop-up message to tell the other dude to get his ass online,is there a way to display a message on a target pc's screen without a client application running and actively listening for an incoming command?

Basically I've written two Apps (A and B) and all I want to do is put a link on the menu of App A which when clicked will fire-up App B.
Normally what I'd do is something along the lines of...
Shell("C:PathAppName.exe")
However, both of my apps are installed on the target machines via a Setup-Kit generated by the Publish Wizard in VB.NET. As far as I know, after you've run the Setup you don't get an EXE file for the actual application - you just get an 'Application Reference' on the Start Menu and/or Desktop.
My problem is that I don't really understand what the Application Reference is and how my application is actually deployed onto the target machine after setup has finished...
Given that I don't seem to have an EXE file after running Setup, I need another way of telling App A to fire App B, because I'm guessing I can't use my Shell command anymore?

I have created a setup project that after the installation, starts the app that is being installed. To do that I have added an Installer class to the app I want to get started and I am using it's commited event to start the app (Process.Start("...myapp.exe").
While this works fine on XP, on Windows Vista the application gets started as a "System" user which makes some parts of the app missbehave i.e. retreiving special folders of the user etc...
This is the question: way to start myapp as the logged in user? Mind you I will not have the credentials of the users.

Which 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.

I have an application that starts one of two external CAD applications depending upon the extension of a file in a ListView. I have been able to start up the application to view the file selected without a problem. I also have a seperate print click event for printing the file that opens the viewer application in the background and prints the file. This works perfectly for one of the CAD viewers but when I select a file that requires the other viewer application to print I get a Win32 exception and an error message stating that the file is not associated with any application and it cannot be opened. This of course is rediculous as it opens fine in the "View File" click event that opens the viewer to check the drawing.
One rather strange observation is that the CAD viewer that does print the associated file will launch the other CAD viewer application (that is associated with the other file extensions) when the "View" click event is handled even though I had not incuded the code to execute the process to start the viewer for that type of file. I realize this rather convoluted and may lie in the ProcessStartInfo arguments that I pass to the application.
Here's a code snippet:
Private Sub PrintFinGoods_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PrintFinGoods.Click
Dim message As String = "No application is associated with file"
Dim source_exception As New Exception

I have created an application where from the starting class a modless dialog box is called. Once the dialog box is called then the program will close instead of waiting on the dialog box to call the appropriate functions.
A couple of notes: This was originally written in VB 2005, and I was successful by manipulating the automatically generated code for the starting and clean up for the class. I cannot find this section of code in my VB 2008 project.
I cannot start the program from inside the dialog box, since there are multiple dialog boxes and which one starts depends on what is currently running on the computer.
The program will run with a modal dialog box, but it does not function properly, so I must use modless.
Please help me to prevent the application from closing when it reaches the end of the code in the main subroutine. I want to have a function to explicitly close the application.

I want to display a message box to inform a user of a requirement. In this case, the requirement is to insert a USB flash drive. This is easy enough:
MessageBox.Show(blah, blah, blah)
This message box will only have an OK button. What I need to happen is this:The OK button should not be available (enabled) until after the flash drive has had a chance to initialize. We will say this takes 2-4 seconds. So how to I keep the OK button disabled during this time and then enable after the time has passed?

If I create a user level application setting and bind it to a text box on a form, then type something in the textbox, the value is automatically saved and when the application is launched again the value appears in the textbox. This doesn't happen when I scope the setting as application.
Why are application scoped settings not saved automatically like user scoped settings are?
If this is by design, how can I manually save these settings and load them at runtime?
