Forms :: Close Form - App With Vb 2010 Which Holds A Mainform
Oct 24, 2010I'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:

View 1 RepliesMake My Mainform Invisible?
Mar 10, 2010I made a birthdaylist. You can store birthdays in it, and it will alert you on the day a person has his birthday. To do that the program has to startup when the computer starts up, and give the alert if neccesary and then close itself again. This all works, but the mainform is visible in that period.

Jan 15, 2010I'm trying to go to a different form my main form and while I'm using the selected form I want the MainForm to hide. I've put the code MainForm.Hide() at the top of the code of the JobInformationForm where I'm directing the program. I thought this would cause the MainForm window to hide. However, I'm getting an error saying Declaration is Expected. How do I use this MainForm.Hide() feature?

Position A Messagebox In The Center Of MainForm ?
Nov 12, 2009Is it possible to position a messagebox in the center of your MainForm instead of the center of the computer screen? This is really confusing for beginner computer users, if your mainform will be in the top left corner and the message box in the middle of the screen, it won't be very clear that the messagebox belongs to your application. (well to us it is, but not to old people).
View 3 RepliesSharing Data Between Classes And Mainform?
Apr 13, 2011I have done programs in the past with VB6 using the winsock control to receive data to be processed. I would like to do the same thing in vb.net but I am having problems. I have done numerous searches and consulted numerous books and articles, but haven't found the best approach for accomplishing the following.
I would like from 1 to 20 clients to be able to send a string to the server to be processed. It would be nice to if the clients could connect to same port and use async processes to open/accept more connections. One of the books (Visual Basic 2008 Recipes) has a recipe for creating "Multithreaded TCP Server that supports Asynchronous Communications".
I am trying to base my program off of that example and modify it for my application. The problem I am having is how to share data with the Main form and the classes that handle the communications. The TCP class has two classes contained in it. One class for listening for connection, beginning the accept client and the other class (clienthandler) for completing the connection and getting the data. I would to be able to get the data from the clienthandler class and post on the main form. I have trying to have a public property for the data but I think my confusion comes in because the clienthandler would be created new for every new client. The mainform would not know how many of the new clienthandlers were created etc.how get the data to the main form and clear the data when done. I have even considered putting data into MSMQ and having main form pull data out.
Windows Forms: LoginForm And MainForm?
Jun 14, 2010Currently, I have a LoginForm that authenticates a user and it works fine. I have a MainForm, which is displayed if a valid username and password is entered. I have done this by using the following code in my LoginForm:Private Sub OK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles
[Code]...
Now this does exactly what I want except I fear it's a work around and it's not the best approach. Also, note that I am using Me.Hide() to hide the LoginForm, is there a way to show the MainForm and then close the LoginForm instead of hiding it? Doesn't Me.Hide() call creates an overhead?

Aug 13, 2011I'm creating an app, with a splashscreen, loginform (just enter a name) and a mainform.With I use my.settings.

Programmatically Set Either A Splash Screen OR The MainForm When The Application Starts Up?
Jan 27, 2011I 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?
Accomplish Is For The User To Select A Menu Item(New Tester) From The MainForm?
Oct 9, 2010What I'm trying to accomplish is for the user to select a menu item(New Tester) from the MainForm(only used for menu)to open the NewTesterForm and enter a rating from 1 to 10( 10 being the best) for two different drinks. When the user clicks the ok button on the NewTesterForm it adds the new rating to the totals. It keeps adding the rating totals until a user clicks the cancel button which returns to the MainForm. When the user clicks on the MainForm menu item Summary, The SummaryForm opens and displays:
-average rating for each drink which drink had a higher rating(the name of the drink)the total number of testers
