VS 2008 : Speed Up The Loading Of The Form?
Aug 12, 2009
A button click event on my main form calls:
frmPanelSchedule.Show()
In the frmPanelSchedule form's load event I am loading 84 labels, 84 comboboxes, 420 textboxes, and 84 buttons.
The form takes a long time to load.Is there a way to speed up the loading of the form?
Private Sub frmpanel1Schedule_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
' create pole labels
lblPole(1) = New Label
With lblPole(1)
[code]....

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.

I was currently writting a Cyber Cafe for the client side which start up with a form that maximize and block all the client control like shortcut key and other security. It's fine to work in my pc and it take only about 5 second to startup the application and lock the client. But when i run the application in a pc that installed with games, it took about 40 second to run my apllication. I notice in task manager panel, the process need to read the whole application before it could load my first form. Is there any idea i can speed up my loading time? I have try to set the process priority to "real time" and startup using batch files, but it still need 30 second to load my first form.

It has the ability to recursively grab all .wmv and .mp3 files in any chosen folder, and add them to a playlist.When opening the playlist, my program adds all the songs to an array, then starts adding the songs to a listview, categorizing them by song, artist, album, and genre, using a dll to access the ID3v1 tags on the .mp3 file.It can successfully create playlists of thousands of songs at a somewhat okay speed, the problem is loading that into the categorized listview.It used around 75% of my friend's CPU while loading his 5k+ song playlist into the listview, and it never finished after loading it in for a couple minutes (it auto updates as it loads, because it is done in a new thread.) It never finished because his OS has a bug where, if the CPU usage is over 100% for more then a few mins, it BSOD's, but that's beside the point.
His CPU, by the way, is a quad core 2.33 GHZ processor.The listview loads thousands of songs by using a lot of CPU [low amount of RAM, less then 40MB 99% of the time], and it does it slowly. [code]I've already redone the sub once or twice to speed it up, and at the moment it's 2-3.,

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.

I want to create a form that, when starting, will display in a ListBox the content of a txt file. I know the file is read because I can display the content in a MsgBox. Here's a snippet of what I tried so far:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim filein As String = "MyProjects.txt"
Dim objReader As New System.IO.StreamReader(filein)
ListBox1.Text = objReader.ReadToEnd
objReader.Close()
End Sub
When I debug my app, ListBox1 is empty.

on this program you have a ability to choose items from a list lets say
Apple
Blueberry
Cheese
when you push button1 and have selected an Item from the combo box, it launches That form
Dim times As Integer
Dim name1 As String
name1 = ComboBox1.SelectedItem
[code]....
(it used to be Object instead of string when I dim'd name1)

During Loading a form, I bind a datasource property of the DGV to the bindingsource, and then set the fillweight property of the DGV columns. But, after form being shown, earlier set properties are being reseted to default = 100.
The procedure is like:
1. TestForm.Show()
2. TestForm_Load(...) Hnadles MyBase.Load
DGV.DataSource = bindingsource
DGV.columns(0).fillweight = 80
DGV.columns(1).fillweight = 120
3. Me.close() (Closing the form which called TestForm.Show()
And now I have visible a TestForm with well binded datasouce seeing all the columns, but their fillweith property was beeing reseted...

I have an MDI Form that contains an MDI Child form. On this child form is a flexgrid. When the user double clicks on a row in the flexgrid this loads another MDI Child form. I have set the following properties on the second child form:
FormBorderStyle = FixedDialog
MaximizeBox = False
MinimizeBox = False
StartPosition = CenterScreen
WindowState = Normal
The problem is that if the first MDI child form is in a maximized state and the user double clicks on the flex grid, the second child form loads in a maximized state too! How can I stop this?

Say you press and hold down a letter on your keyboard. The first letter gets added, there is a delay and then it repeats quickly on screen. Is it possible to skip this delay and go straight to the repeating part? I realize this might not be a visual basic question as much as a windows question, but if there is some way of toggleing it through my program, or using a workaround, i would like to hear the alternatives ^^ Setting the windows setting to fastest still has a small delay and others users would still experience it on other computers.

My application works fine.However, I am connecting to 5 DBF files and the queries are very slow.[If I copy the DBF files to the local hard drive everything runs fast enough. 30-40 seconds vs. 1-1.5 minutes]The DBF needs to stay on the network.I am hoping that using the index will speed things up enough.Can anyone tell me how or give me a code example on how to index on DBF files?

i am trying to complete a project. My task is to read large TXT files (300 files, 2.2 GB in total) read the customers inside, perform some data calculation and write each customer data to a separate txt file.
I made a code in VB6, it runs fine, however it takes 8 days to run on a quadcore processor, utilizing 20-30% of the CPU. Now I upgraded the code and am running on VB.NET 2008, the latest version. The speed still remains the same, and the CPU usage is also about the same.
Anyway I can make this process faster. I have a quadcore PC with 8GB of ram, possible to maybe make VB utilize all the CPU say 100%? so it executes atleast 2 to 3 times faster.
