Two Forms 1. "SplashForm" 2. "MainForm" I want to load "MainForm" AS background Process of "SplashForm" process when "SplashForm" process end i just want to show the "MainForm" which should be already loaded code
[code]...
How do I make a splash screen with a progressbar that value changes base on the MainForm_load event? Example:When the mainform finished executing part of mainform_load, the progress bar in the splash screen changes to X value (eg 50)When mainform_load is executed completely, the progress bar moves to 100%, the splashscreen closes and mainform opens.
View 1 RepliesI have a code which when used, firstly application will run the Splash Screen application. Splash Screen will be active for several second, and then the main of application will show in full screen. Before the user use the application, user must Log in first. This works but the problem is that it loads the splash and login form twice. To worsen the situation, the second login form that appears gives access to the system even when the cancel button is clicked while the first login form just works fine. My codes for the three forms are as listed below:

Is there a way to load the data for my form during the splash screen and simply show the form when the user clicks on the button? I'm using a thread which fills my DataAdapter using Form.DataAdapter.Fill(Form.Dataset.Table), but when I open the form the data isn't shown (I removed the line from my form_load event to prevent a double load). Is there anyway to tell the form that the DataAdapter has been filled already and to look at the information there instead of loading the data everytime the form loads?
My problem is that the form takes a while to load due to the amount of data it is looking for. If I could already have the data ready and then display the form when the user clicks a button it'd be perfect. I apologize if I'm missing something, this is my first time diving into VB.Net with VS2010 after using Access VBA for awhile.
I would like to display my splash screen for a set amount of time (5 seconds). While the splash screen is displayed, I added code to the load function to determine which form to load next. I have the splash screen selected in the Application Properties settings. I also have to select a "Startup form:" in the Application Properties settings.
I'm having a couple of problems. First, the form selected in the "Startup form:" is loaded and displayed along with the splash screen.Next, the form I select in the splash screen load is not started. Only the "Startup form:" is loaded.
Let's say I want to put a 10 second delay on my splash screen before loading the next form or app.I use a timer, but would it be a simple integer value or several different lines of code?
View 3 RepliesI have created a splash screen and would like it to display for 5 seconds and then display the MainMenu form. The book I am following suggested using
Threading.Thread.Sleep(5000)
but it just makes the splash screen APPEAR after 5 seconds of nothing.
I want to build in the Mongoose web server into my application. My program consists of a form and a module. The module contains the Mongoose code copied from here: [URL] If I call the Main() function in the module from my form's Load event then the web server starts correctly and I can connect to it. However, that's as far as the applicaiton goes - my form doesn't load up. I guess this is because my application is only single threaded and the Mongoose code basically puts the thread into sleep mode waiting for a http request.
So, the question is how do I go about getting Mongoose into a separate thread that starts up when my application starts, but then allows my form to load and be operable?
To create splash screen before InitializeComponent, the WithEvents statement for the BackgroundWorker component needs to be moved from the Form's Designer.vb file into the constructor as indicated in the first commented lines of the constructor below.

I know one can select Spash Screen as the application startup as per this illustration. I can't do that however because the application is called by another program which passes in parameters via Process.Start(). Depending on the passed in arguments, I need to either
Go Directly to the MainForm or Go First to a Splash Screen which will then to the the Mainform after 5 seconds.
I definitely need Step 2 above because of the slow startup time of creating an SocketConnection and the population of some Custom Controls only after the Socket connection has been established.
Would I use a startup class or module and then use that as the application startup 'form' which could be establishing the SocketConnection while also launching a Splash Screen?
I have a MainForm which has tab Control and several independent form. I open each Individual From in the tab of the main form. A "Close Tab" button on the MainFrom closes the current tab, its implementation is below.
This closes the current tab but what I also need is to dispose the From whose tab is closed but I am not sure how to get the instance of the form.'[code]...
What is the best way to access a value of a control within a form outside of the form class. I have a lot of functions defined in a module, one of these functions requires a series of values from controls in my main form such as the FolderBrowserDialog.SelectedPath element. I understand that these cannot be accessed in the format form.FolderBrowserDialog1.SelectedPath and that they need to be accessed using a delegate. This is the part I am stuck with.

I've made an app with vb 2010, which holds a mainform. On it is a menutoolstrip with button, when I click on that button a second form is opened on a second monitor and the button is being checked (different color).
When I click the button again, it is unchecked, but the form on the second monitor is still open, while it should be closed.
Here is the code I use:
CODE:
Imports System.Data
Imports System.Data.OleDb
Public Class Form1
Dim con As OleDbConnection
Dim cmd As OleDbCommand
[CODE]...............
The insertion part of the form works great. But my problem is in the form load part......If i leave a field blank(Null),then perform Save operation,close the form after successful insertion and then reopen the form,then it retains the previous values during the form load......This is only in case where i leave a field blank in the previous data entry in the database.......But if i enter values in all fields then form load is working great.
How can I load a form and allow it to run it's code in the form load but keep it not visible. I want it to do what it needs to but but not display.
View 3 RepliesI have a few forms that have a lot of really intensive updating along with a great deal of user interface (text boxes, button clicking etc) Is it possible to open a separate form as a separate UI thread from the start up form that called it to "show" or open or whatever the new method might be?
View 6 RepliesI have a code in vb.net 2010 which when executed,should load the splash screen for a few seconds,then load the main form,but this main form will only be active after a user logs in with the correct password.I have implemented the code but its giving me an error of two splash screens and two login forms.The 1st splash appears which gives way to the login form.When i enter the correct password and click OK,it again displays another splash screen which again gives way to a second login form.The second login form even has a bigger problem.It logs me into the system even when i click the cancel button.

While my program loading, I have a splash screen. After the program is done loading my Splash-screen closes and the main form (form1) shows (all good up to that point). But the problem is after the Splash-screen I cannot close form 1, nor can I move it. here is what have.
[Code]...
I'm writing a small app which I want to display a splash screen. The problem is my form 1 is appearing before the splash screen disappears. In fact is appears on startup blocking the splash screen. I have some code in form_load and have managed to figure out which line is causing the error, but I cant figure out why or how to prevent it.
The line reads
LoadSettings()
If I comment out this line everything runs fine and there's nothing in that sub that should affect form1. I'm doing this in vb express 2010.
Here's the code for my form_load:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
LoadSettings() ' this line is causing the problem
My.Application.MinimumSplashScreenDisplayTime = intSSDelay * 1000
'resolution check

was trying to make a splash screen using a form (so that it fades in and out) however i cant get it to stop for the person to read it (at least for 5 seconds) this is the code

I am experiencing an annoying problem with my second for when it opens. Here is the code :
If
My.Settings.NoSplash Then
Me.Hide()
[Code].....
None of these makes any difference. If issue a Close() on form1, the entire program closes and not just form1. Is there a property I need to tweak or set on either of the forms to stop/fix this?
What I am trying to do is show a splash screen then the next form. I have given them the option to "skip" the splash screen if they don't want to see it any longer and this is where I am having the problem.
I have a splash form that opens in the following Sub of the main form of the app[code]...
The Splash Form opens and closes fine, but no controls (a text box and a graphic, on a panel) appear on the form. I knew I was probably missing something (this was far easier than anything I found searching), but at least the form opens and closes. The app actually starts with a SubMain, which is only used to control how it opens with it's registered file type.
I have a settings form and a main form the main for collects information from the settings for and stores it into variables (public XXXX as string) but on my Save button it is supposed to save the information in the main form and show the main form. But it get an error on the first line containing: "MainForm.VARIABLE", The innerMessage says it cant create the form or something, but here is the code from my save button:
(I know that this isn't the right block of code because this doesn't really show anything, but if anyother code is required then just tell me and ill post it. The error actually occurs on "MainForm" itself, how do i fix this?)
Error is: An error occurred creating the form. See Exception.InnerException for details. The error is: Object reference not set to an instance of an object.

MainBot.Max = txt_Max.Text

How do i load the Main form of a WPF so that a seperate thread goes and gets data from the database while the form is in an apartmentstate? (drag-able / movable) I Know this is possible with opening a new window from your main form like this :
Private Sub openOrderWindow()
Dim OrderWindow As Orders = New Orders
OrderWindow.ShowDialog()
End Sub
[code]....
I've tried putting MyBase.ShowDialog() and .Show() and .9000+ other things The only benefit I've got out of using a seperate thread to load from the databse is i can see the screen right away (as oppose to it being a transparent box until it loads) but i cannot move it around or minimize it?is there any way to make it Movable while it loads?
i am asking about using the progress bar into the status bar to move when i load any child form inside the MDIParent form.
View 1 RepliesWe created a vb.net desktop application in Microsoft visual studio 2005, in deployment phase we found that the application are vary slow in startup (Splash screen), we try many solution (ngen, remove unused name space, code, references) to speed the load but we could not solve it.
View 5 RepliesHello.. I'm using a splash screen for the first time in an exercise. I have it set up to display the splash screen before going to the main form. I made changes to the splash screen title and copyright information. When I execute the program, the splash screen comes up but it's not displaying the information I changed. When I view the splash screen the changes are saved. It displays the project name where the application name should be.
