Screen Blanks After 1 Min Of Processing (of Excel File) / Refresh Or Freeze Screen To Avoid Blank Screen?

Jun 29, 2011

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?

.net - Taking Photo Of Screen - Take A Picture Of The Entire Screen, Not Just The Focused Window?

Jul 6, 2011

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.

Putting VB Content In The Center Of A Full Screen With Variant Screen Size?

Feb 2, 2012

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.

Get Coordinates On Screen By Holding Down Mouse And Placing It Over Different Parts Of The Screen

Feb 29, 2012

I'm trying to get coordinates on my screen by holding down my mouse and placing it over different parts of the screen.

Make A Screen Recorder (not Screen Capture) Program

Aug 20, 2010

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?

VS 2008 Screen.GetWorkingArea And PointToScreen - Dual Screen ?

Mar 28, 2009

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?

Screen Sizing - Max=stuck - Won't Get Off The Max Screen Size

Feb 11, 2011

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.

IDE :: 64 Bit Browser - Completely Blank Screen ?

Limiting FPS To Screen Refresh?

Apr 19, 2009

I have made a game (real time strategy) and it is running rather fast on my 3 GHz quad 8800 GTX, namely, it runs around 200 FPS usually when there are like 80 units and tanks in a forest fighting.

I would like to limit the FPS. So far my limitation code is pretty buggy... it does limit, but wrongly:

Private Sub LoopGame()
Do While GameIsNotPaused
FPS += 1

[Code]....

Also, after I solve this weird issue, should I set the value to monitor's refresh value which is usually 60 Hz on LCDs? Or should I set it to 30 or what ?

Use Of Progress Bar During Screen Refresh?

Jun 16, 2011

I have a Windows Form application that allows the user to delete several rows of textbox data at a time (i.e., using checkboxes).  It takes a few seconds for this to occur and I was thinking about using a progress bar w/in the "delete rows" subroutine.  It's also kind of "choppy" while the windows form refreshes.  I'm new to this aspect of VB (2010) and how to make the screen refresh appear more professional.  Apart from possibly using the progress bar, maybe there is also a way to dim the window until the refresh finishes?

Avoid Screen Flickering When Painting Graphics On A Windows Form?

GDI+: Update Or Refresh Only Certain Parts Of The Screen ?

Jan 30, 2010

I'm making a game using vb.net and GDI+. I've been encountering frame rate problems and one solution that was suggested to me was to only refresh certain parts of the screen. I was also told one way to make this happen was to use rectangle or region structures and since I already have these as hitboxes it seems like a perfect way to efficiently reduce the drop in frame rate.

The only problem is that I have no idea how this would work and so far my google searches have been fruitless. Yet again I turn to this very helpful forum, can anyone help me? By the way I've set doublebuffered to true on my form to get rid of the annoying flicker.

Questions. How do I update or refresh only certain parts of the screen?

I'm using a timer set to tick every millisecond to run everything and it refreshes the screen every 2 milliseconds simply using me.invalidate; each time it ticks things move a little bit and stuff happens that triggers other events etc. The problem is that when the framerate supposedly "drops" things start to change. "Bullets" and projectiles appear to travel many times faster and much less smoothly than they do when there a less objects moving on the screen, it's almost as if the timer runs faster... What's the reason for this? Is there a way I can change this? I remember hearing about a "stopwatch" or something that someone used in their game that was more consistent or something.

Also I'm aware that vb.net with GDI+ isn't exactly the best language to make a video game in but it's for a school project and I have no choice in the matter.

Screen Refresh Speed Is Not Fast Enough?

Jul 3, 2008

I am looking for help on how to speed up VB.NET (or C#) screen refresh speed. Specifically I need to update many controls and then refresh them on the screen all at once.I am in charge of writing a .NET interface for an older legacy program. Because this needs to run on slow legacy machines I did a performance test and discovered the screen refresh speeds of VB6 is faster then .NET. In VB6 there is barely a flicker as controls change across the entire form all at once. In VB.NET you can see controls change moving across the form like a wave. I must be doing something wrong...

To do a head to head comparison I put together equivalent VB6 and VB.NET programs, each with a maximized form and 48 labels. Clicking on any label changes the background color of all the labels on the form. To really see the problem it is best to try the following code on a slower machine (1GHz etc.)

In VB6 create a project MyProject and add a form MyForm with the following properties

Caption = "Screen Refresh test VB6"
BackColor = Black
WindowState = Maximized

On that form add a label MyLabel with the following properties:

Index = 0
Caption = "Hello World"
BackColor = Cyan

In the form add the following code:

Invalidating Splash Screen - Picture Box Doesn't Refresh With Image

Jun 21, 2010

I have a splash screen and want to test the loading bar. The % of loading are in 11 stages (0-100% in 10% intervals) and I have 11 different images. What i'm trying to do is set my picturebox.image = to the resource image and then wait 1 second then set picturebox.image to the next resource image. What i was doing is on the SplashScreen.Show method [Code]. What happens is that the picture box doesn't refresh with the image until the last image has been loaded from the procedure and the end of making the thread sleep completes. (this worked fine in VS2005). How can I make it load up the image, redraw the picturebox and then make the thread sleep for 1 second in VS2008.

Print Screen Paste To PictureBox And Save To File?

I am new to VB and having an issue with Print Screen.  I'm trying to take a screen shot, show it in a picBox and then save the image to a file.  Eventually, I want to add a timer and have the webcam open on screen so that I can take a set of pictures and save them to the hard drive (a very simple "security" cam).What's happening is when I click on my "Start" button the screen shot always seems capture the last screen event (ie: if I move the dialog from left to right and click "Start" the dialog is still showing on left side of screen shot).  Not sure what's going on with this.  I tried variations to update (picBox.Refresh(), .Update(), and .Show()) without any change.  It's as if two clicks are required to make a capture.Also, I'm trying to save the image that's been captured and can't seem to get that working.

Option Explicit On
Option Strict On
Public Class Form1
