View 29 RepliesWindows Forms VB Application.. I added a splashScreen to my application. And it was flashing only for a second then going away so I added a sleep timer to my Form Load event... The problem is now the splashScreen stays open even After Application exits, instead of simply closing at the end of the sleeptimer.. The Part of the Form Load event that is causing this is as follows:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Me.Load
Threading.Thread.Sleep(5000)

I am running VS 2010 Professional and have a solution with 3 VB projects in it. I can open the forms in 2 of the projects just fine but if I try to open any of the forms in the 3rd project I get a message saying "There is no editor available for .....Form1.vb. Make sure the application for file type (.vb) is installed". Everything was working fine last month and I could open any of the forms.
Again the problem is limited to just the 1 project in the solution.
just curious if there was a way to make the text in a message box scroll across the message box

View 2 RepliesI 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.
View 1 RepliesI want to allow my user to add urls to a database, much as a user might add file names. I have a form with a label, a textbox, and a browse button. I would like the browse button to load the user's default browser and then have the final url appear in the textbox when the browser closes. I have not been able to do that, but I have come close. I have not found a way to capture the url from an arbitray browser, so I instead load ie.exe and then capture the url with an OnQuit handler. That works (even verified by the debugger) but I am unable to get the url to appear in the textbox without actually clicking in the textbox once ie closes. I would like a suggestion as to how to avoid making my user click in the textbox and, if possible, to load the user's default browser and still capture the url. Here is my code for the Browse button (IE is defined at the class level as Dim WithEvents IE As SHDocVw.InternetExplorer):
theURL = ""
IE = New SHDocVw.InternetExplorer
AddHandler IE.OnQuit, AddressOf HandleIEQuit

Im working on a silverlight application where a user can create, edit, delete objects. The changes they make are placed in a queue which is processed every 4 minutes. When it is processed, the updates are sent over an async web method call to be saved in a sql database, one at a time. When the first update finishes, the next starts.Im having a problem when a user makes a change and then exits the browser app before the 4 minute timer has expired.Currently the changes are getting lost.Ive built on what the guy working on this before me has done, and explored the Dispose and Finalize methods, trying to start the update process when the factory is being shut down, but that isnt working due to the async nature of the web service calls. I get errors saying needed objects have already been disposed of.
View 1 RepliesI had originally saved the project I was working on to my desktop, but now I have moved the folder to another location on my hard drive (didn't want it on my desktop anymore).

I'm running a bunch of automated tasks in a thread I'm creating via the Thread class. So I'm not using a BackgroundWorker.
During parts of the automation, the thread may exit. This is normal. But when the thread completes, I need to finish up some additional tasks. I can anticipate all of the conditions in which the thread closes, but I'd rather not to do the final tasks at each point, as this will create a lot of redundant code.
So instead, I wanted to write an event that is triggered when the thread exits. I looked through the Thread class, but all I could find was the ThreadState property, which has a Stopped property. But, when I try to add a handler to that property, it doesn't allow me.
For some reason, the next code found on MSDN crashes or exits after 30 cycles or, in other words, after processing 30th Property, exits without explanation. As I said, I found it in MSDN

View 2 RepliesI was wondering if it was possible to make custom message box options. What I mean is, I'm going to have a button that pops up a message box. The message box will say, for example, "What is 10 x 10?" and I want there to be three options, instead of a Yes/No type of thing: "1000", "100", and "20". Is there a way of doing that? Or would I have to create my own message box using some software?
