I feel like a complete noob for asking this because I know how to do this in VB6... But in VB.NET 2008, how would you load a new form and unload the current one? I know that in VB6 the code would be:
[code]...
The problem with that code is that it just ends my program completely without showing frmMain.
I'm rewriting a vb6 program in vb.net, and I was wondering what the best alternative is to vb6's "load"/"unload" commands for loading and unloading controls on a form.
e.g. (VB6)
Unload frmContainer.DetailGrid1
Load frmContainer.DetailGrid1
Currently I am adding/removing controls using
[Code].....
Problem
Forms:
1) Splash1
2) frmMain
Purpose:
unloading splash1 and loading frmMain
Code used so far:

Problem:
The Whole project is ended!
Problem2: How to Create and .exe?
Basic Problem: I Have started programming in VB.net today only, I have experience of 2 years in VB6.
I'm planning on a private software, that I wish that have multiple pages, like a installer. It will not be a installer or anything, and I don't want to use tabs on it (it doesn't fit to what I'm thinking.) How can I do it? I've tought on multiple forms, but I don't see how can I load another form while I hide the current 'on-the-fly'.
View 4 RepliesI am learning VB.NET and as a first task I am creating a login form. I've been trying to link it to another form once a correct username and password are entered. However, despite that I still cant be able to hide it or unload it once the next form is loaded.
Here is the Code
Private Sub OK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OK.Click
If UsernameTextBox.Text = "chris" And PasswordTextBox.Text = "chrispass" Then
Me.Hide()
Form2.Show()
End If
Me.Close()
End Sub
The Form2 appears as coded above but the 'Me.Hide()' manages to hide the login form but then it appears again.
I am using VB.NET 2003. I am trying to move an application from VB5 to VB.NET and having some difficulty. Thre is a Main Form, which only consists of a menu bar with one of its commands being "Help" Under "Help" are several choices, including "About". There is also an About form. My question is: How do I get the About form to load when the Help/About command is clicked?

I am currently writing a program that is saving user setting for the program into the registry. The problem is with the 'Administrator Control Panel' that I am writing for that program. To load/edit those settings for users that are not logged in their NTUser.dat must be loaded into the registry. I have based that part off of [url]... using the API functions RegLoadKey and RegUnloadKey. When all that is done is loading and unloading the key it works fine. However, any time that I read from the loaded registry user hive it will not unload that users registry hive. I have tryed using the RegistryKey class[url]...
My assumption is that the RegistryKey is not being closed or released properly, or completely enough for the user hive to unload. I have tried the .Close member in the RegistryKey class as well as tried 'CType(regKey, IDisposable).Dispose()' (regKey is defind as registrykey) to close the registykey. After I close the program (running from Visual Studio) I can manually unload the hive via regedit.
Is there another/better/more complete way to close the registrykey to allow for the RegUnloadKey function to work?

So if anyone has fallowed any of my post, then you will know I'm still in the process of transferring to pure vb.Net, while simultaneously trying to rid any bad habits that stemmed from the good 'ol vb6 days.So having said I have a few question that are in regards to the GarbageCollector. Now I'm not looking to modify or mess with it at all, but rather it's exact functionality and where I should be disposing of and handling my own unloading.For the sake of my coding style I like to run my application differently than most(unless this is the way it should be done) but this only applies to my more large project.[code]
So as you can already guess my startup object is the AppMain sub, and I have the application framework disabled.I'm not sure how the Garbage Collecter functions, so truly I'm not sure if my code there is necessary or unnecessary. What it does is unloads all open forms that may have been left behind, plus it closes the database connection if one is open. Also I'm wondering if its a good idea to clear all my collection as well. My concern with the collections is just I have sooo much information being stored(it's a business management system that handles transactions, appointments, inventory clients employees etc etc) and this keeps growing. So I'm not really sure if all this gets handled automatically by the GarbageCollector or if it's good practice to begin clearing out this data and disposing it before hand.
Im Using VB 2008. I have MsgBox() statements in all Mouse & Form Click events to TEST & NOTHING FIRES during Form Load when I click on Form or Button Controls !!! The Form Load event contains code for Displaying the Label.Text control many times with changes in the Text to simmulate annimation.

I am after some code to load another form when the user closes the current form. I have tried this
[Code]...
When I use
Me.Close()
Form1.Show()
It closes the whole app.
How would I change it so that it only closes the current form while opening a new one? EDIT: I put [Not Resolved] Because I accidently pressed the resolved thing
Is there a way to turn off all visual updates to a .NET form while I am manipulating it? When my program first loads, for example, I set the tab control to the tab that was last open. The user can see the program switching tabs.
I have looked into SuspendLayout and ResumeLayout, but either I don't understand what they are doing, or I am not using them correctly, because they don't seem to have any effect. Someone told me that there used to be a way to turn off paint events in VB 6. Does this still exist in .NET?
I have 2 forms. When a user clicks something on form1, form2 pops up. After user is done with form2 and closes it (where the dataset is updated), I want form1 to "reload" the dataset to reflect changes made in form2.

View 4 RepliesHow 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 itis there any way to make it Movable while it loads?
Does anyone know of anyway that it would be possible to speed up the process of loading forms.With VB6, forms (simple ones) was extremely fast but with VB.net, the initial loading of a form (even the simplest one) takes very long. Although it gets better once it's loaded once and the reloaded the next time (almost instanttaneous), but the first time loading gives a bad impression to any user that .net is actually much slower.
View 7 RepliesI've got 2 forms; form1 and form2.
Button1 is added to form1.
When I click button1, I want to close form1 and open form2.
I tried the following.
me.close
form2.show
Its not working. Form1 gets closed but form2 is not showing up.
When I use the following code
me.hide
form2.show, its working.
But hide will not unload form1 and it will still occupy memory.
In my form3 i have this code
Private Sub Form3_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Is there anyway to prevent this from occuring?

I have done this before with Ajax but its alot of work and my site is not a Ajax enabled site.
Problem: Form hasn't fully initialize but shortcut keys can be usedDetails: Launch an mdi child with database access retrieving data, and user is already using the shortcut keys while the data is still been retrieve which results to error since object hasn't fully initialize yet.
Goal: Hinder user from using shortcut keys by disabling the keys at initialization then enabling it after all objects are good to go.
Another Situation is:A form with a gridview and a button.I got a hotkey that when press, handles a gridview getfocus event.
The problem is that the gridview is still making its instance and when press the hotkey, it activates the getfocus property of that gridview(which is still creating its instance).
