I have this application that fetches huge chunks of data from databases and i would like to have a loading screen, or simple image (gif) appearing on top while the app is working... but what normally happens is the whole application locks up. How can I make a certain part of my application still responsive while the rest loads?
View 1 RepliesI created a heavy application in vb.net 2005. And on start up of main form it doing lot of things like
1. Check New Software Update taking 15sec
2. Check Registration taking 15 Sec
3. Initialize Software also take almost 20 sec
First my application show Splash Screen and do 2 operations like
1. Check Update
2. Registration
So i want to do this First show Splash Screen and
-same time it start 3rd Process and remain Hide Main Form
-Same time it perform 1st and 2nd operation if pass then just show 3rd step without time waist.
I do it with delegates threading but it is not doing both operations same time.
I have combo box being filled with more than 50 thousand records. it is getting sometime to load and bind the data. I am using datatable to bind the data. I tried using data-reader as well but in vain.

View 7 RepliesWhen i try to view MDIParent screen in designer mode I'm getting below exception...
`Could not find endpoint element with name 'NetTcpBinding_IMyService' and contract 'ClientProxy.IMyService' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this name could be found in the client element.'
Little background to understand my question more clearly...
I've a WCF server which I'm trying to consume in my Winform application. So i've created a separate class library in which i added service reference and created a proxy. I've copied the client endpoint info from app.config in class library to UI app.config file.
When i run the application everything is working fine but when i try to open MDIParent screen in designer mode its throwing above exception.
Note: I think i'm getting error because i'm trying to create a proxy object on NEW method (form constractor) if i comment that line - i'm able to view designer screen.

View 6 RepliesI have a few combo boxes that need to be loaded up once and displayed multiple times (whenever the main form is opened) The reason for this is because it's taking about 10 seconds for the form to load each time it's opened due to unnecessary re-querying.

View 1 RepliesIm 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.

what's the best way to stop a form from displaying in its Load event.I initialise a form using the following code:
Dim MyForm as new MyCustomForm
In the Load event of MyCustomForm, I ask the user to select a folder and use that to populate a listbox on the form.folder.If the user presses Cancel instead of selecting a folder, I don't want to display the form. Right now, I just call Me.Close in the Load event, but that still causes the form to briefly appear and disappear in the background. Also do I need to call Me.Dispose?
im making a web browser, but i dont know how to make a progress bar load when im loading a page. Please note that im using TabControl, so you cant use the WebBrowser function.Also i was wondering if you could add that little thing in the bottom left that says "connecting to http://..." and "transfering data from..." etc.

Okay, so I have been developing my own MP3 player recently, and now I thought I would make the player remember what songs were in the playlist when it shut down. It now remembers the playlist file that was used last, but I would still rather make it so that it remembers all the songs without saving the playlist.
I've been using a setting to save the playlist file, but when I try this:
...it doesn't work. The savedSongs is a System.Collections.ListArray. Heres the code at Form_Load I'm using at the moment.
Dim loadSongs As New System.Collections.ArrayList
loadSongs = ExperimentalPlayer.My.Settings.savedSongs
lbl_songname.Text = ""
[Code].....
Should I use some other kind of variable to save the filepaths? Well, the other option is that I use a text file for that, but I'd rather make it like this.
I love to experiment with linqpad, but now my task requires heavy computing power. Trying to do it on my computer is painful. My friend has a much more powerful computer than I -- can I execute some operations from my linqpad on his computer? I don't have RDP access, but I can run any .NET program on his computer.
If it is not possible, then is there any FREE service that provides computing power? Maybe a hosting trial or something. I know that Windows Azure offers a 30-day trial, but it has a very slow CPU module and in my country, MS partners cannot be expected to fix service sites when they go down.
I would like to use C# for an application I'm building, but the application makes heavy use of automation (i.e. Excel, Word).
Is it feasible to use C# for such an application? It used to be a nightmare to use C type languages for things like parameter lists with null arguments etc..?

I'm building a VB.NET 2010 app that tracks battery usage. Run the app, start logging, then let the battery go flat. At the end, you get a nice graph that shows you how long the battery took to run down. Compare it to previous results and you can see how battery life is doing.
But this is supposed to be an unattended app, so it's not feasible for me to sit down and use word, browse the Internet, listen to music, play games etc. for four hours (especially at work!), so I'm looking for a way to artificially increase CPU usage to chew through the battery faster, and simulate how a battery would probably be used throughout a work day.
I've managed to inflate the memory usage using:
Dim a as long
Dim ptr(0 To 20000) As IntPtr
For a = 1 To 20000

I increase CPU usage in VB.NET? I've tried creating new threads with constant loops, but I get the funny feeling that VB.NET optimizes these kind of things to prevent memory and CPU hogging apps from taking over

I'm looking for some advice on a very simple application which should consist of 2 parts:The application should display a splash screen for 5 seconds Before the splash screen displays, the program should execute code which sets some Environment Variables and then starts another EXE after which this application should terminate. As a complete novice to VB.Net I've been reading countless articles & examples on splash screens but they all seem geared towards a solution which will load a further form after the splash screen or contain snippets of code that I have no idea how or where to use. On my app however, I don't want any further form to be visible so can someone please advise the steps to follow that will achieve what I am looking for.
The following code Forum Account kindly converted that sets the environment variables and starts another EXE

View 7 RepliesIs there a way to load the data for my form during the splash screen and simply show the form when the user clicks on the button? I'm using a thread which fills my DataAdapter using Form.DataAdapter.Fill(Form.Dataset.Table), but when I open the form the data isn't shown (I removed the line from my form_load event to prevent a double load). Is there anyway to tell the form that the DataAdapter has been filled already and to look at the information there instead of loading the data everytime the form loads?
My problem is that the form takes a while to load due to the amount of data it is looking for. If I could already have the data ready and then display the form when the user clicks a button it'd be perfect. I apologize if I'm missing something, this is my first time diving into VB.Net with VS2010 after using Access VBA for awhile.
I'm trying to figure out how to resize a form on load to fit to the user's screen. Many of my users are on laptops, or split screens between laptop and monitor..I remember in VB6, it was something like form.height = screen.height (or something of the sort)... but I can't find this functionality in VB.NET 2008. I'm also trying to wrap everything (multiple screens/forms) into one app, so I wanted to know if anyone was aware of any tutorials on form parent/child relationships... I don't want to keep opening and hiding forms individually without having them packaged in one work area....
View 9 RepliesI would like to display my splash screen for a set amount of time (5 seconds). While the splash screen is displayed, I added code to the load function to determine which form to load next. I have the splash screen selected in the Application Properties settings. I also have to select a "Startup form:" in the Application Properties settings.
I'm having a couple of problems. First, the form selected in the "Startup form:" is loaded and displayed along with the splash screen.Next, the form I select in the splash screen load is not started. Only the "Startup form:" is loaded.
