Jan 31, 2009I want to disallow changes to two comboboxes unless the user first clicks a LOCK symbol on the screen. I pop a Y or N into the tag of the picture box when they click it...I've got this - combobox is called LanguageTo
Private Sub LanguageTo_Enter(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LanguageTo.Enter
If Me.languageLock.Tag.ToString = "Y" Then
MessageBox.Show("Click LOCK symbol to allow changes to the Language Pair!", "Language is Locked!", MessageBoxButtons.OK, MessageBoxIcon.Exclamation)
[code]....
How do I "cancel" the attempt to change that combobox?I don't want to ENABLE=FALSE the combobox - as I don't want it's image to visually change. I want to allow them to attempt the change and then abort it if they didn't unlock first.
Screen Blanks After 1 Min Of Processing (of Excel File) / Refresh Or Freeze Screen To Avoid Blank Screen?
Jun 29, 2011BTW 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?

Jul 6, 2011Currently 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, 2012Now 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 :

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, 2012I'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:

View 3 RepliesMake A Screen Recorder (not Screen Capture) Program
Aug 20, 2010I 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?

View 1 RepliesVS 2008 Screen.GetWorkingArea And PointToScreen - Dual Screen ?
Mar 28, 2009I 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?

View 3 RepliesScreen Sizing - Max=stuck - Won't Get Off The Max Screen Size
Feb 11, 2011VB.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.
