Show A SplashScreen While The Main Form Loads In The Background?
Aug 14, 2011
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?

I have an app that connects to a remote database.The connection to the database is triggered by the form load event of the main start up form which prompts the user for user name and a password.Here is my problem:Sometimes it takes a number of seconds for the database connection to be established after the user has double clicked the desktop icon. this means that during this period it appears that no action is taking place until the startup form becomes visible.Some impatient users assume that nothing is happening and double click the icon again.What I want to do is to have a graphic image or something pop up on the screen immediately when the program starts that displays something like 'Connecting To Database, please be patient"

I was wondering if there was a way to trim the working set when the main form loads in vb. I know in C# you can use
SetProcessWorkingSetSize(GetCurrentProcess, -1, -1) API call
But I am not quite sure how to implement this in vb. Basically I got an application that is showing 11,000K+ mem usage in the task manager when in actuality it is really only utilizing about 1,000K if that and I want to try and trim the working set to show the actual usage in the task manager rather than what the framework is reserving.

I am trying to get a label to show briefly (3 seconds) when the form loads. The following code gives the 3 seconds, but the label doesn't show. The label is set to visible in the Designer properties.
'hide label1 after 3 seconds
Threading.Thread.Sleep(3000)
Label1.Visible = False
Adding 'Label1.Visible = True before the sleep function doesn't help.

The first column in my Data Grid is actually not my first column. It has an arrow pointed to the first row and then the last row has an asterisk by it. Is there anyway to make this column not show every time my form loads?

how i can refresh my main form background image once a user picks a different image as the background.I have 2 forms namely Form1 (main form) and form2 from where the user can select the image he or she would like to set as the background image of form1.But the problem is that after selecting the image file from form2,when form1 is opened the background image doesnt change and remains the same as before.Only when the user ends the program and re-runs it again the image changes.
I tried
Form1.reload()

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.

I am using background worker to report progress on the screen. In the Main.vb I have the following
Public Sub report(ByVal sender As System.Object, ByVal e As System.ComponentModel.ProgressChangedEventArgs) Handles bwlistener.ProgressChanged
Dim message As String = e.UserState
logRTB.AppendText(message & vbCrLf)
End Sub
When I call this from Main.vb I use:
bwlistener.ReportProgress(0, "Some status text goes here")
It works great. The problem is when I try to call it from any other module in my project.
When I call it OtherFile.vb:
Main.bwlistener.ReportProgress(0, "Some status text goes here")
It doesn't work... The program doesn't crash. Debug goes through everything but no output is actually shown to the end user.

Dim PB As ProgressBar
Private Sub main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub

I have a couple of user controls, which I show in my main form.
So let's say here's what i want:
Sub Show_Control1()
UserControl1.Show
'CODE TO HIDE EVERY OTHER DISPLAYED USER CONTROL ON THE MAIN FORM
End sub
Right now I have to hide them one by one with hide, because I don't know what's the current displayed form.

Q1: How can i make it so that my window that i want to show as a drop down does not appear to take the focus off the main form that is calling it?
Q2: The form that is dropping down has the FormBorderStyle Property set to None - thus the window does not have a drop down shadow - how can I make the popup window have a shadow?

Type 'Microsoft.Office.Interop.Access.Application' is not defined.
Type 'dao.DBEngine' is not defined.

What I'm trying to do is show a form while a background process is running. Similar to a progress bar but not a progress bar. We have a form that has an animated gif (customer request) and that's it. no other controls. They want this form to show while the processing in the background is running.

When I press "Show Desktop" button in the taskbar my main form "disappears". The only way to show it again is by pressing an other program which is open in the taskbar (lets say Word) to rise and unrise again.

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?

I have a form that it do some calculations on datas,I create another form (for example progressform) that has a progressbar and a label with text:"Please Wait. I use progressform.SHOW() in first line of my analysis form load event, but when I run the project the progress form loads incompletely and you can not see the label and progressbar in the form! if I add a messagebox.SHOW("anything") after the line progressform.SHOW() the problem will solve and the label and progressbar apear in the form. it seems that before the progressform loads completely the computer starts the analysis...

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 use background worker almost daily and works great. Today I came to an instance though where I needed to put my background worker in a separate project then the one I was running because I needed to use this class in two different projects in my solution. When I tested the coding on a winforms form, it works perfectly, handling my coding on the background thread. When I try to reference this class from an external project, all of my coding seems to run just fine, but it does not appear to be doing anything on a background thread as it should be, causing my main window to lockup.
Is there any way around this / what is the best practice for ASYNC calls in an external class.Note I basically created a class that u call start, and an event fires when data is ready, so it's not like my external project is waiting for the method to complete.
Solution ABC has two projects. Project A and Project B. Project A is my WPF application and B is my DLL doing the work. Inside project A I have
Dim SmartCardData as new Solution.B()
SmartCardData.Start()
Project B has a sub
