I designed a application on vb.net 2005. Some of the forms in this application has databindings controls. Now when such forms loads it takes some time. I want a splash screen containg "Please wait" message to appear till the form loads and the wait splash screen would be shown for every several forms in the application not only before the start up form.

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'm trying to create a program that will look at a website and check it for updates, similar to an RSS feed. It then will show a dialog (Form2) that will inform the user that there is an update.Form1 is used as the configuration form and is able to be shown via a notify icon in the system tray, which is on Form1.Originally I would have Form1 hidden via Me.Hide() and then run a timer which would check for the updates and call Form2.ShowDialog() when there's an update, I found out however, that if Form1 is hidden, the dialog will not show.
Next I tried not Hiding the form, but instead setting its ShowinTaskbar property to False. At this point the program functions correctly, however when I minimize Form1 it sits in a shrunken window near the task bar... Is there any way to completely hide Form1 (when minimized), and allow Form2 to be shown as a dialog?

I'm using a DLL in vb.net 2005, and this dll show a messagebox with OK option. I would like to close this Messagebox by code.
I was investigating to use SetWindowsHookEx, but I can not detect it. Is it possible to don't show any dialog, or detect the dialog using the dll name?

I often use the process of displaying a dialog from a form, with the dialog user input then used to update the main form without any problem. In a new scenerio I launch the main application screen, I then show a login dialog ontop of the main app screen and can launch another dialog from the login if a new user is required. The plan is to update the login dialog (updating a combobox to reflect the addition of a new user) from the new user dialog.
See code below :-
'Update login forms user list as new user added successfully
frmRoomBookingLogin.cboLogin.DataSource = Nothing
frmRoomBookingLogin.txtPassword.Text = "Updating password from dialog"
MessageBox.Show("The password text is " & frmRoomBookingLogin.txtPassword.Text)
[code]....
The messagebox implies the dialog has been updated yet the text does not change. Is it possible to update the dialog when using a setup such as Form -> dialog -> dialog? I'm intrigued as why the dialog does not reflect changes. I have never refreshed/repainted the dialog as never required to in my other examples when updating a form from a dialog and never encountered a problem when using a two tier form setup.

I'm having trouble with MDI child and a dialog form. The problem details are listed below:
1. One MDI Parent form (Form1) with a button on it (Button1).
2. One Child form of Form1 (name = Form2) with a button (Button2) and a textbox (text_box1).
3. Another form in the project (not child of Form1 and not MDI Parent) with name Form3. This form has also a button on it (Button3).
The application behaviour is as follows: the application starts with Form1. Clicking the Button1 will show Form2. Form2 correctly opened as a MDI child. Clicking the Button2 on the Form2 will show Form3 as dialog (Form3.ShowDialog() ). Clicking the Button3 on the Form3 need to do the magical thing - to set/change the text in the Form2's text_box1.
Tried various examples from this forum. Also followed a lot of examples from net. Nothing works. Tried to create a writable property in the Form2 class but calling it from the Form3 does nothing.
I tried to access the MDIchildren(ss) while ss loops in MDIchildrens array but I don't know how to access the label control inside the Form2 using this technique. Successfully changed the Form2 caption but no controls are available in VB intellisense - practically correct because VB don't know which form from array I'm referring to.

I'm developing an application that should run on a 'kind of' mobile device. It's not exactly a mobile device (hence I'm not developing in the mobile framework, just winforms), but I can't use various Forms either.
Right now I am working on a proof of concept, and I simulated the mobile device simply with a UserControl that has a fixed size. Everything needs to happen on that UserControl, and I cannot display any other forms.
However, I now need a 'Dialog Form' to let the user enter some data (mainly text but it doesn't really matter). What I'm doing now is simply showing a Panel with a TextBox, OK button and Cancel button. I bring that panel to the front, hiding the rest of the application, when required. The different Panels (there's also one for a CheckBox, ComboBox, and the main application is also on a Panel) are all on a 'PanelContainer' UserControl I made, and I can switch panels simply by specifying their 'key' (a string such as "TEXT", "CHECK", "COMBO" etc). So I can display the textbox panel by simply doing
panelContainer1.SelectedKey = "TEXT" That brings the textbox panel to the front.
What I want now is that I can 'show' the panel as if it were a Dialog form. That means that the code 'waits' until the user has entered his text and either clicked OK or Cancel. Then I could use it like this
' Show the panel here
Dim result As DialogResult = panelContainer1.Panels("TEXT").ShowDialog()
' and immediately use the result (the code won't come here until the user has selected ok or cancel)

I 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:

After deploying and installing my application I use the app to create and save a file with my own file extension. After the file is created I right-click on the file and select Open With.. so that I can associate this file extension with my application. In the Open With dialog I use the Browse button to find my application and select it. In the Open With dialog the application icon is shown, but the name of the app is blank (looks like an empty string). Can anyone tell me why this might be happening? I've looked at the Registry, which shows the correct app, but every time I open the Open With dialog only the application icon is displayed, no name.

In my gridviews item template for my edit button I have the following to call the function. Which works to show an alert but can't get it to show the dialog? Is it because possibly the postback happening on the grid causing it to close?

I 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.

I have a dual monitor setup on my computer. My program has multiple forms. I've designed the program to check which monitor the main form is currently on and to open the secondary forms on the current monitor. When the main form is on the primary monitor the secondary forms open as FormWindowState.Normal which is the design-time setting for the secondary forms. If the main form is on the secondary monitor and I click to open a secondary form then the secondary form is to be displayed as FormWindowState.Maximised.
[Code]...
So I moved the Form.Show line to after the Form.WindowState line. This works fine when the Form.Show process is very quick. The problem is that one of the secondary forms downloads some information from the internet so it takes about a second to finish the Form_Load process. When I had Form.Show first the form would not appear on screen until the Form_Load process is complete, so the delay was in the form appearing at all which is how I prefer it. With Form.Show last the form appears on screen immediately but appears mostly blank and unresponsive until the Form_Load process completes.
I would prefer that the form not appear at all until the Form_Load process is complete but I would like it to appear in an already Maximised state. Is this achieveable? It doesn't seem that complicated but I just can't figure it out.
