i have a problem with de Cursor.Current Handle.
in a Drag & Drop event i have to check if the Cursor is the Double Arrow Icon to resize the Cell now i use
if Cursor.Current.Handle = 65553 Or Cursor.Current.Handle = 65555 Then
in Vista it works well.. but in XP the Handle for the same Icon is not the same..
sure, i can add the other 2 Handles.. but thats not really a proper solution.
In my VB.net Winforms application I'm using the ITaskbarList3::SetOverlayIcon interface to set status overlays on the application's taskbar button (under Windows 7). This all seems to work fine for me, with the icons being shown and removed correctly.From the form load event, one of my functions makes the callSetOverlayIcon(parentForm.Handle, IntPtr.Zero, String.Empty)(where parentForm is the form which the load event has fired for) which very occasionally (on other people's machines) throws the following exception:
System.Runtime.InteropServices.COMException (0x8007057A): Invalid cursor handle. (Exception from HRESULT: 0x8007057A)
at MyNamespace.TaskbarNotify.ITaskbarList3.SetOverlayIcon(IntPtr hwnd, IntPtr hIcon,
[code].....
Why does SetOverlayIcon throw an 'Invalid cursor handle' COMException occasionally
View 1 Replieshow can i get the current position of the cursor in real time inside a picturebox?
View 2 RepliesI'm trying to create a hook to monitor the current position of the mouse cursor. Nothing important, I just need to count some pixels during interface design and wanted to learn how to create a hook, so I decided to go for a hard way instead of a sane way.
I've found example code which declares the following function:
<DllImport("User32.dll", CharSet:=CharSet.Auto, _
CallingConvention:=CallingConvention.StdCall)> _
Public Overloads Shared Function SetWindowsHookEx _
[Code].....
But Appdomain.GetCurrentThreadID generates the warning: "'Public Shared Function GetCurrentThreadId() As Integer' is obsolete: 'AppDomain.GetCurrentThreadId has been deprecated because it does not provide a stable Id when managed threads are running on fibers (aka lightweight threads). To get a stable identifier for a managed thread, use the ManagedThreadId property on Thread."
I've tried using ManagedThreadID, but that doesn't work. The thread ID returned seems to be the logical thread ID of the thread, as it runs in the .net runtime, rather than the Win32 thread identifier.
Calling the function ith AppDomain.GetCurrentThreadID works, but I really would like to have a "stable identifier" for my thread.
Can someone explain to me whether it is possible to use ManagedThreadID in this context (I assume not) and, if not, the things I need to avoid in order to stop the AppDomain.CurrentThreadID from becoming "unstable"?
how can I get the current cursor state (Hand or IBeam or ...etc) .. at any active window not only at my form

View 1 RepliesI am been working on an a small app that has a Forms.Webbrowser control that navigates to a Adobe Flash program. I have developed the app on Vista 32bit platform and have had no problems. I have sent the app to a couple of people to test out and one is using Vista 64bit and is running into a problem. I know the webbrowser control just uses the underlying base framework of IE. The problem on the 64 bit machine is when the site is navigated to it says that it needs to have Flash installed. When the user goes to Adobe's site it says they need to use a 32bit browser.
As stated on Adobe site here:[URL] the Flash player need to be in a 32 bit browser. What options do I have to be able fix this problem? Is there another control that I can use that would be the same in a 32bit platform and 64bit platform? Besides navigating to the Flash program, the browser also goes to standard web pages.

View 3 RepliesThis VS010 solution is not providing my intended outcome as a custom override of a 'crosshair' or 'reticle' cursor e.Graphics.DrawPath() is the function that isn't working. This

I have a user control, and want to be able to update its cursor while it is disabled. For example, say that I have a user control whose cursor is Default. The below code works ONLY when the user control is already enabled; if it is disabled the below code doesn't work and the cursor remains Default: Me.MY_USER_CONTROL.Cursor = System.Windows.Forms.Cursors.WaitCursor

View 5 RepliesI have a custom cursor that I have as a ico file as cur files are only mono coloured and 32x32.
The only problem in using a ico file is that I can't set where the hot spot is and at the moment it is set in the middle of the icon which is no help
I was looking on the msdn website and it said to set the hotspot like this
Dim instance As Cursor
Dim value As Point
value = instance.HotSpot But I don't know how to set the point value to (0,54) which is where I want the hotspot to be located.

View 1 RepliesI wrote an application to handle a joystick with directinput. It works fine if it uses the handle of the main window but it doesnt happen the same if the handle is the one of the component that contains the joystick's operation.
I mean:
main form handle: 15
component handle (which is inside the window and the joystick needs the focus of this component to work): 25
It always work if the handle i initilizate the device is the main form (15).How can i use only the handle of the component?

I have a datagridview having 3 columns (qty,scraft factor,actuall qty). What I want is if the user encode 50 in qty and 2 in scraf factor, actuall qty will automatically computed based on qty multiply by 2. I was using keyup event. Now I am using endedit to get the current value of the current row and column, now the problem is if the amount to be encoded is more than one digit it will not accept because of endedit. What event do I have to used? or any solution with this scenario.
