Multithreading/Loading Screen?
Jul 30, 2010
I have an application, when the user clicks on a button it will open the 'view form', which loads data from a database into a listview.This takes a while if there is alot of data in the database table.How do i create a loading screen (asuming i need to make a new form as the loading screen) which appears while the application is loading the data into the listview. And once the process is finish, the loading screen will close and the 'view form' opens.

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?

When 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.

I 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. Here is an example of what I have as a combobox source and what I've done. I've put the query, connection, etc... in a module and call it on the login form - I don't get any errors but the data does not load into the combos.
'In Module
sql = "SELECT DIR_ID, DIR_NM FROM LTC_FBS_DIR ORDER BY DIR_NM ASC"
RConStr = String.Format(RConStrFormat, LoginForm.txtUser.Text, LoginForm.txtPass.Text)
'using instead of dim connemp
Dim connemp4 As System.Data.OleDb.OleDbConnection = New System.Data.OleDb.OleDbConnection(RConStr)

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.

BTW this issue occurs in any MS office program when the VB.Net (or even VBA) is processing information.Example: In Excel, a worksheet is displayed on the screen. I start either, a VB.Net or VBA procedure and within 30 seconds the Excel worksheet (previously displayed) blanks out. In both VB.Net and VBA,ScreenUpdating = False. My expectation is that the previously displayed screen would stay static as if I left my desk to get a cup of coffee; came back and the same ole Excel worksheet was still there?Of course, setting VBA Screen Updating = False accomplishes two goals: 1) speeds up processing and 2) saves the user from seeing unnecessary "garbage-processing" steps.Why does VBA or VB.Net ScreenUpdating = False not freeze the screen at the time of its invoking?

I have a window application develpoed in vs 2008, framework 3.5, in which i have put a button.. Now where i click that button the other text boxes are filled up with the data from database thru web service.. what i want is while all text boxes are being filled i want to show an animated loading gif image till data loading is completed in all the text boxes.. i have tried to use image picture box but while data is loading gif image is displyes but in static mode.. cant see animation... i think this is because data loading and animation both are done thru one UI thread..

Currently I have the following VB.NET code to make a screenshot of my desktop, but it only takes a picture of the active screen:
Public Function SaveScreen(ByVal theFile As String) As Boolean
Try
SendKeys.Send("%{PRTSC}")[code].....
The following code is how I execute the above function, if it makes any difference, which I don't think it does:
SaveScreen("C:Lexer_tracescreen.png")
Now, I need to be able to take a picture of the entire screen, not just the focused window.

Now I'm creating at app in VB (Microsoft's, Visual Basic 2010) which will be in full screen but I want to know if I can put all my content in the centre of the screen. At the moment it's at the far top, left of the screen. When the screen size varies I want it will stay in the middle for all shapes and sizes. Like :
<div style="margin: 0 auto; width: 500px;"></div>
But this is for web pages using HTML and CSS.

I'm trying to get coordinates on my screen by holding down my mouse and placing it over different parts of the screen. I'm using the mouse_up and down events in a button to kinda simulate the mouse being held down. The problem I'm running into is that anytime I go past the button's bounds, the coordinates I want stop. This is what I have so far:

I have created a GUI and have set my 'Form1' window to match that of my PC monitor ( 1280x1024 ). However when i move the project to work on my netbook, the screen on my netbook is only 1024x600 and half my GUI is missing. Is there any way i can adjust my settings so that my 'Form1' GUI will auto adjust and display in full on both screen when i move the project back and forth?

I send a message a while ago and no one answerd, how can I draw directly on the screen (not on a specific window) just on the screen, neither if it's on the desktop or anything else.Is there is any option to bring up the switch between applications window (Alt + Tab), I don't want to use sendkeys because the user need to keep the key down and I just want the user to select the application with his mouse.

I am making a program that will put a black mask over an application (like a full screened game). This black mask will fade in and out, depending on certain criteria. Is there a way I can do that with VB? It's to help me dim my monitor without having to push anything.

I wanted to make a screen recorder (not screen capture) program, but I am not entirely sure how to get it started. I have seen many videos and things on how to make one, but all of these just take multiple pictures and then don't compile them into a movie file, and I don't want to take many pictures (unless that is the only way possible.) I am using Visual Basic 2010 Express and I have looked at the Windows Media Encoder, but I can't seem to figure out how to use/implement it (yes, I have downloaded and installed it.) Maybe I can use some kind of ActiveX control?

In my project is a form called "Secondary". It is suppose to appear on any and all screens (if any) other than the primary screen. The following code seems pretty logical to me, but Secondary is not appearing on any screen.

I have a button btnRegEx that when pressed shows a ContextMenuStrip, similar to the '>' button in the Find/Replace dialog in Visual Studio when you are using Regular Expressions. I have a ContextMenuStrip cms which I show using its Show(x,y) method.
At first I was simply setting x and y (the location of the ContextMenuStrip) to some point next to the button, but I noticed that when the button is close to the edge of the screen it goes off screen. I wanted to prevent that so I built some logic into the x-y calculation. When the ContextMenuStrip width is larger than the 'remaining space left' I simply show it more to the left. Same for its Height of course. I am using the Screen.GetWorkingArea(point) method to determine the 'remaining space left'. As I understand it, it returns the working area closest to the point you specify (to which I pass the button's location).
As long as I stay on my first monitor, it is all working perfectly fine. The problem occurs when I move the form to my second monitor. The contextmenustrip is still showing on the first monitor for some reason...
Here is the code I am using:
vb.net Private Sub btnRegEx_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRegEx.Click
Dim p As Point = PointToScreen(New Point(btnRegEx.Left, btnRegEx.Top))
Dim x, y As Integer
[CODE]...
I have noticed that when I click the button when the form is on the second monitor, the buttons location (p) is calculated with the first monitor's top-left corner as (0,0), even though it is on the second monitor. This way, the GetWorkingArea function returns something like 1280, while the buttons x-location is something like 1700... So, how do I get the buttons coordinate relative to the actual screen it is on, rather than the entire dual monitor screens as a whole?

I am in a dual monitor environment. I have developed an application using VB.NET 2005.When I start my application, the splash screen always displays on the monitor where the mouse cursor is at, even if it is not the same monitor that the login and primary form open on.

VB.net / VisualStudio8 I have an application I've written that's been very stable. I had it set to exactly 1024x768 resolution, and to windowsstate=maximize (I think that's what it's always been).
I recently started coding to give the user the option to use the 1024x768 or to have the program detect the max size of the screen and use it.
That part works great... I'm using:
Dim MonitorWidth = Screen.PrimaryScreen.Bounds.Width
Dim MonitorHeight = Screen.PrimaryScreen.Bounds.Height
Me.Height = MonitorHeight
Me.Width = MonitorWidth
What I'm baffled by is that the application now won't get off the max screen size. It's using the max of the screen, even when I do not call the screen resizing code above. I'm trying to give the user the option of the application only taking up 1024x768 (and placed up to the top left) or maximizing the application using the full extents of the screen.
