VB: Update Progressbar On Splashscreen
Apr 1, 2011
Main form loads and displays a table of records. Form1_load goes through each record and looks up external data for updates and this takes noticeable time. I have a splash screen that comes up while the main form is loading and I want the splash screen to display the status in a progress bar named ProgBar. I recall the method used a 'delegate' and my SplashScreen1 uses this code:
Delegate
Sub UpdateBar(ByVal
X As
Long)
[Code]....
The main form already loops through each record and all I want it to do is update the progress bar if the splash screen is open.

I'm having trouble getting a progress bar to update. I'd be okay just with a moving marquee bar. Basically, I'm reading a database routine in a SqliteReader.vb class. I need to use the worker_DoWork routine, but I'm not sure how to expose my variables coming from Form1: graphData, graphComputations, m_debug to the worker_DoWork sub. How is this usually done?

I place some code below to simplify the process.
1) I am trying to use background worker to download a large file and update a progress bar to reflect the changes as the large 5GB file is being downloaded, and also update percentage completed to the label.text(lblInfo).
2) As I was goggling I came across some info that a web client is needed to calculate the maximum size of the file and divide by 100 and you can stream it down with the web client. Reading it is one thing, implementing it is another as I spent week trying to get it to work.

I have a program that runs for some time and I would like to update the user on its progress. The rest of the GUI is updated using Delegates and Invokes and such (Java is Soooo much cleaner in this regard - everything is thread safe!!), but there is no invoke method for the progress bar. How can I use a delegate to update the progress bar when there is no invoke to invoke!!

With my project I have created a small splash screen called splashscreen1.vb
In my project form2-is startup form [MDI-Parent].So where I have to mention this splash screen to load first?
And how many forms can be included with one project?

Simple question but I can't seem to find the answer - can someone tell me which event causes the splash screen to be closed.
I thought it would be either the startupform.Activated or some application level event but I can't find it.
The reason for the question is that I want to control when the splash screen is closed myself - can I do this?

I 'm working on a quite large VB application, and recently I started profiling the memory usage, because there were some issues with objects not being collected.I noticed that the SplashScreen (boilerplate SplashScreen hooked up via Project Properties) never gets collected, because is remains referenced by My.MyProject.MyForms.m_SplashScreen. This is apparantly a private member, and I can't figure out how and where to set it to nothing with reflection code.I looked into my code to make sure i'm not doing anything special; I don't even reference the form anywhere.

this is the error I started getting only when I added a splashscreen to my application. Please note that I haven't added any code there - on the contrary - I removed everything from the Splash class. The issue seems not to occur when debugging - I got it from my Virtual machine - what makes the problem a bit more complicated as I have no idea which line may cause it. The problem shows up between splash_screen_dispose and main_show (when I click continue all is ok).
The details of my err. message:See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

I am using Visual Basic Express Edition 2008. I want my main (and only) form to not be re-sizeable.
FormBorderStyle = FormBorderStyle.FixedDialog
To my main form load function. However, when I add this code, the form loads over my splashscreen. I am trying to have my splash screen displayed for a set amount of time

I have set a splash screen form as the application splash screen in VB.net 2008 I have set a form login as the start object. On load event it executes inital process. It runs fine except when the form login, during executing inital process, must be display a modal form, a messagebox, etc. because these are displayed behind the splash screen. How I can do it to show the msgbox, form dialog at the front?

So I'm developing a game and it's a little heavy on some systems, so here's what I would like to do when the game opens (pseudo code):
Show Splashscreen
Load GameForm
When GameForm Is Completely Loaded
Splashscreen Close
Show GameForm
How is this done in actual VB code?

I defined a procedure in splash screen to check application trial time, but now it is still working after deleting the procedure from splash screen form. I am not able to understand why and from where it is working.

I have a splash screen for my program that I want to have a background image that changes each time the program opens.One way I saw to do this is to load it from a ImageList, but that has an maximum image size of 256x256.The splash screen is 498 x 305, which means that I need to find something besides ImageList but hopefully with a similar ability to organize the images.I did try just putting them into resources, but wasn't able to get it to set the background without erroring, and I'd prefer not to have 30 images cluttering the place up.

Windows 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 have created a project that shows a splash screen first and then shows the main form once the main form has been fully loaded. I only want to show my splash screen once the main form has completely loaded in the background. My main form by itself takes like 3 seconds to load, so I would like to display the splash screen for about 3 seconds and then show the main form because the main form will then be fully loaded, but instead it shows the splash screen for 3 seconds and then the main form still has to load anyway.How can I load the main form in the background and then show it when it is fully loaded?

We have two update panels on our webpage. Now first update panel is having button cancel. While second update panel is having a file upload control.Now if the user uploads a file that is going to upload in about 2 mins, and in between, say after 30 seconds the user clicks the cancel button, the upload taking place in update panel 2 should stop.

I'm making an application with a custom progress bar (picture box) using the formula
pbxProgress.Width = (intValue / intMax) * pbxBar.Width
where pbxBar.Width is the maximum length.Along with that, I'm using another formula to change the RGB color of pbxProgress while it increases. I'm using:
pbxProgress.BackColor = Color.FromArgb(0, 0, (intColor / 255) * 650)
I came to that last number; 650, by guessing and checking. If I use that number, the RGB increases perfectly with the value of the progress bar so that it ends up being at 255 when the bar is completely full. The only trouble is, I'm not sure how I got that number, and I would like to make a more general formula for future use.
