VS 2008 - Bunch Of Errors - Main Login Box And Then Fail To Show The Main Screen
Jul 28, 2009
My app works fine on the development machine and 3 other machines. However, some machines just show the main login box and then fail to show the main screen. There is no error message. I installed VS 2008 express on on of such machines and when i compile the project, the following errors appear:
Type 'Microsoft.Office.Interop.Access.Application' is not defined.
Type 'dao.DBEngine' is not defined.

I've created a windows form application in vb 2010. I've got all my forms complete and now want to add a Login screen. One the login screen, after the username/password is entered and OK is pressed, I try to open the a connection string. Obviously if the connection fails, the user has entered the incorrect credentials. If the credentials are ok, True is returned and I then open up the Main form that shows the correct items for the logged in user.

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"

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?

Ok i have a login window which connects to a MySQL database and authenticates the user. Works perfect, BUT
If rowsEffected > 0 Then
cnMySQL.Close()
LoginForm1.Close()
MainForm.Show()
Else
cnMySQL.Close()
MsgBox("Login Failed!")
End If
That's supposed to close the login form and open the main form if the query returned a positive match of the login information. The login works, closes the login form, opens the main form, than mysteriously exits the application. I'm guessing its something simple but i don't see it .. the main form has nothing in it besides some inputs and labels no subs at all and if i change the form which the program starts to to the main form it runs as designed.
I know usually if you start your program from a module and use Application.Run() you can keep the thread open, but this is all forms no background work so i didn't want to go that direction.P.S. i just removed LoginForm1.Close() and it logs me in fine and opens the main form fine and keeps the app running but the login form is still open.

I'm a beginner VB.Net programmer using VS 2008.I'm planning a new winform project whose main form should look more or less like this:
[Code]...
The user can either choose from the Main Menu (by clicking an item) or enter the item number in the textbox. For example, if the user clicks DoSomething3 in the Main Menu (or alternatively enters 3 in the textbox), another form will be opened and hide the main form.What would be the best way to implement it?Specifically, I would like to know how I make so that choosing from the menu and entering a number in the textbox fire the same event.

Hello.. 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.

I 'm running a multithreaded VB.NET program. After running a particular task in the environment I'm displaying a MessageBox to indicate that the task is complete. Everything works fine, sending data, receiving data, displaying the data, etc. When I display the MessageBox and I click outside the MessageBox, the MessageBox goes behind my Main Screen.

I am having a difficulty in this login form that I have made. The same as the premade template login in VB 2008 which I am using right now.Here's what happens when I run the program Log in form open > Log in successful > Main window appears *The login form still does not disappear.
I tried hiding it via me.hide() Log in form open > log in successful > Main window appears > log in form disappear.*Now the problem is that I cant close the whole application because the login form is still there only hidden. Again I tried putting in the "EXIT" button the code me.close() login.close()Log in form open > log in successful > Main window appears > log in form disappears > Exit application *Now everything seems to be ok now and then I found another problem.Instead of clicking the exit button I tried clicking the X button on the main window. There I found out that it only closes the main window. Therefore not closing the whole application because the login form is still hidden.

I have a button in Main screen, which calls A.exe when you pressed on it.
Process.Start("A.exe").
If I exit from Main, how can I make sure A.exe is closed too? Application.Exit in Main doesnt seems to work.

Im trying make my application display my splash screen for 5secs before loading my main form. I have read lots of threads on this and they all seem to point to the following:Add the following code to the New() sub of the splashscreen.
My.Application.MinimumSplashScreenDisplayTime = 5000
I have also seen a suggestion to add the following code to the OnInitilalize event in the ApplicationsEvents file.
Me.MinimumSplashScreenDisplayTime = 5000
I've have tried both ways, and although it successfully makes my splashscreen wait 5 seconds before closing, it doesnt prevent the Main form from waiting for the splashscreen to close before loading. The mainform simply loads over the top of the splashscreen.This thread is exactly what im after but i cant seem to get mine to work.

I have application framework enabled. I have my startup form set to my main form, and i have set my splashscreen in the application tab of my project properties. Im using VS2008.I also noticed that when i clicked on the "View Application Events" button in the application tab of my project properties, the file was blank. I have seen that some other people have had problems with this. I just cut and paste the following code into my ApplicationEvents file. Potentially an issue??? Any reason why the code was not auto-generated to begin with?
Namespace My
' The following events are availble for MyApplication:
'
' Startup: Raised when the application starts, before the startup form is created.

I have a project (Written in Visual Basic, using Visual Studio 2005) which has several user controls. I have had no problem setting it up where you click a button and it load a user control, but I cannot get it to remove the control that is currently open. For example The program opens on a starts screen, which has the choices, Control1, Control2, and exit. When you click Control1 button it should open up a screen to display an inventory. It does this just fine, but it does not close the main menu screen.
Here is the code for the initial startup of the project:
Public Class Form4
Public Sub Form4Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim CtrlMain As New ControlMain()
With CtrlMain
.Location = New Point(0, 0

I have a splash screen, the default from Visual studio. It loads up, is shown for a few seconds, then, when it disappears, the main form is loaded. Now here is the problem: the main form appears in the back, behind the windows explorer window I load the application from.
The weird thing is that this only happens on some computers, particularly Windows XP machines.I tried a lot of things like BringToFront() or TopMost = true in the on Load event of the form but nothing seems to change this.

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 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.

I have a solution with more than one project and the main project contains buttons to open forms from different projects that are in the same solution. Say Project1 is the main project and Project2 is the different project that gives the following error when i compile it:
Error 3 'Sub Main' is declared more than once in 'SystemInformation': SystemInformation.Program.Main(), SystemInformation.My.MyApplication.Main(Args() As String) System Information II
I have already seen other threads with this question but it does not work for me because i have more than one project.For Project2: Application Framework is disabled and the startup object is "SubMain".

I have been trying to solve this for 2 days now, every text book I own and google have been well and truely exhausted and I am still no closer to solving my problems.I have a login facility reading in user info from a main user file. This takes all info into a temp array and then splits usernames into a username file, passwords into a password file and a current score in a score file.
I have the login working fine and everything else in my program works as intended but touching up cosmetic aspects I want to add a Message box after login to say hello and display current score. This works great for the first name in the user file i.e - after login User1 welcome to the game. Your current score is 45 As intended.But the problem arises with any other users, my message comes out as
User2 welcome to the game. Your current score is 55 I do not understand where the random new lines are coming from. I have tried assigning the message as a variable and removing new line using

I have made quite a nice and tidy little game. Its based around space invaders and works quite well. however because i have finished my college project almost 2 weeks ahead of the assignments release date, my tutor has asked me to tweak my project and make it better.So far i have added a full main menu to the game and a full splash screen. I would like to add in a section for recorded high scores but have no idea how to attempt this at all.
