VS 2008 RichTextBox - Disable Mouse Scaling?
Apr 17, 2011
Finishing off my control, but I now found a nasty problem. When the user holds the 'Ctrl' key and scrolls the mouse scrollwheel, the control is scaled. I do not want that, since it would make the Font size fail.
I previously made it reset the scale on Control up, but that is just not a very elegant way:
Me.ZoomFactor = 1 I do not want the text scaled at any time, not even while the user is scrolling and it resets afterwards. I got to overriding the 'ProcessCmdKey' but no idea how to catch a scroll or zoom event.
Any way of disabling the RichTextBox scaling (or zooming) so it does not even occur? I have a control that inherits from the RichTextBox.

Im currently in the mid of making a drawing project , and part of it is free drawing using Graphicspath object
now drawing is ok,moving or dragging the drawn path is done using System.Drawing.Drawing2D.Matrix but the problem is using System.Drawing.Drawing2D.Matrix object to scale the graphicspath object results into scaling and moving the drawn graphicspath on the same time ..
any resizing method code is listed below
Public Overrides Sub ResizeShape()
Dim Sqrt As RectangleF = GetBounds()
Dim Dx As Integer = MoveResizeEnd.X - MoveResizeBegin.X

I'm using VS 2008 under Windows 7. When I hover the mouse over a variable in debug mode, the value will fade in slowly. Sometimes it is annoyingly slow, I just want the value to show up, no animation or fading. Or is this fading feature a Windows thing and not a VS thing?

Im using Visual Basic 2008 Express..Is there a way to disable mouse click for a while in Visual Basic 2008, I mean if mouse was clicked more than 1 time in very short time to click only once? -- I need it because my mouse became like crazy one.. when I click once it may clicks twice or more.so until I buy another one, I'd like to filter click, to allow only one click and to block another clicks that were made in last second.

I have a WebBrowserControl on my main form and it auto navigates and all that just fine! What I would like to do is not allow the user to click anywhere within the WebBrowserControl while the program is running. Reason for this is that the browser self-navigates to a view of cameras and this shows scrollbars. My program then takes screenshots of specific coordinates on the screen so I do not want the user to use the scrollbars or highlight or do ANYTHING to the page once the program starts. I would like to change the cursor icon to like a red X or something similar to indicate no user functionality.

What I have so far is a program that moves the mouse around my application. I used a bit a maths as well to make the movement smooth. Here's my code for anyone who is interested:
Code:
Public Sub MoveMouseCursor(ByVal DestinationX, ByVal DestinationY)
Dim DifferenceX As Integer = MousePosition.X - DestinationX
Dim DifferenceY As Integer = MousePosition.Y - DestinationY
[Code].....
Now with my problem. When the program is running, the last thing I want is for the user to be moving the mouse because the program would get disrupted. How can I enable and disable the use of the mouse for the users benefits really because if they even knock the mouse slightly it could cause them a few difficulties. Anyway, I am hardly restricting them from using their computer because there is only one mouse. If they want my program to run, then they will have to except the fact that they can't do something else in the mean time. Also, after the program has finished running, I will need to enable the mouse again.

In my home form I have a splitcontainer and few buttons. When the buttons are clicked respective forms are opened in the splitcontainer. The splitcontainer is anchored- top, left, right, bottom so that when the home form is resized the splitcontainer resizes itself automatically. The controls within the other forms are also anchored properly to resize themselves accordingly. But the problem is when i open a form in the splitcontainer, even if I resize the home form, the controls in the form within the splitcontainer aren't resizing. The reason is when the home form is resized the splitcontainer is resizing itself accordingly but the form inside the splitcontainer isn't (as forms don't have anchor or dock properties so I couldn't set them). As a result though the controls in the sub form are anchored to resize themselves yet they aren't.

I have an application in Visual Basic Express 2008 that just has a Windows Media Player control on a blank form. In order to prevent the user from double clicking which would result in the media player full screening, I want to disable both right and left mouse clicks on the form and Windows Media Player control. Any suggestions?

I am kind of amazed that there is no answer to this anywhere and I mean anywhere. I am looking for a way to disable the keyboard (actually all input) on a computer. There are several threads about it but no one has ever posted any serious, working code. I know someone is going to inevitably ask "why would you want to do that"? Actually why I want to do it is immaterial but if you must know... I am playing with a "USB Keylock". When this USB Keylock is not present in the computer I want to disable the keyboard. When it is present I want to enable the keyboard.

I use a .NET richtextbox and I want to have the EnableAutoDragDrop property set to True. This allows user to drag&drop text, rtf and images around etc. However, I need to process files dropped into the richtextbox myself - I do not want them to be embedded as OLE objects when they are dropped.
How can I overcome this? Is there any way to delete embedded files from richtextbox?
(I've found API DragAcceptFiles which doesn't work for some reason.)

Does anyone know of a way to disable the mouse scroll wheel when a control such as a ombobox or listbox has focus? For my purposes, combobox is all I need the answer for.I have a combobox set to trigger a SQL query on SelectedIndexChanged, and accidentally scrolling the wheel while the combobox has focus causes about six SQL queries to fire off simultaneously.

I have scoured the net for help with this problem of temporarily disabling mouse clicks on a VB Net form and have not been able to find a solution that works.
I'd like to prevent users form clicking on a form when i'm doing some background processing. To me it sounds simple in theory but apparently its not.
