Mouse scrolling works while debugging through IDE, but not when running my application separately...

Posted By:      Posted Date: October 12, 2010    Points: 0   Category :WPF
I have an application with a WindowsFormsHost that is hosting a COM component.  When I run my application through the IDE, my mouse scroll events are handled correctly and the control scrolls as it should.  However, when I run the application by itself, my mouse scroll events don't do anything.  I've tried both Debug and Release builds and they both act the same way....as long as I'm running the app through the IDE, Debug or Release, my mouse scrolls act as they should.  Has anybody run into this type of issue?

HttpHandler works with Visual Studio Development Server debugging, but not otherwise


Hi all,

I'm new to HttpHandlers.  I am writing an HttpHandler that reads uploaded files directly from the request stream to provide progress that can be queried using an AJAX request.  For large files, this seems to be faster than having ASP.NET load the file contents into Request.Files and then streaming the file from there to wherever it goes (Linq to SQL into a VARBINARY column in an SQL Server database.)

My HttpHandler works perfectly when I'm debugging using the Visual Studio Development Server, but doesn't work otherwise.  The application pool for this application in IIS 7 is set to run in Classic Mode, and the Handler Mappings screen in IIS says that I must manage managed handlers in system.web/httpHandlers. 

I set up in my applications Web.config file.

<add verb="GET,POST" path="*.upload" type="Namespace.For.UploadHandler, AssemblyForUploadHandler"/>

It works great, so long as I don't debug with the "Use Local IIS Web server" option.

What else do I need to do to get this to work?

Long running WPF application - Garbage Collection

Hi All, I have a long running WPF application; users start the application and keep it open for at least 6 hours straight. I spend a couple days with a Memory Profiler, solving a couple of memory leaks. According to the Memory Profiler, all is good now. However, when I run the application, and monitor the Memory in the Windows Task Manager, it only seems to grow. When I create a button to force the garbage collection (GC.Collect()), a lot of memory is freed from the app. My questions: 1. I don't feel like it's a good idea to call GC.Collect() explicitly; is there any case where it is advised to do so? 2. Is it normal that it takes WPF that long to start garbage collecting automatically? Thanks, Koen

Why is the scrolling with a scroll wheel on a mouse so choppy in VS.NET 2010?

I have a Microsoft Mouse that contains a scroll wheel used for scrolling the vertical scroll bars in applications. IE, Word, Outlook, Safari, you name it have smooth consistent scrolling when using the wheel.  However in VS.NET 2010 it is real choppy, like the scroll bar moves in steps or increments. Is there a configuration specific to VS.NET 2010 for configuring this?

Print control works on reporting server, but not in embedded in application

Application hangs (100% cpu) outside debugger, but when debugging it runs ok.

Be prepared, this is a tricky one. One of my customers he is building a proof of concept using my software components. When running outside the debugger, the application will hang, using 100% CPU in the main thread. At this point attaching the debugger is unsuccessful. When running inside the debugger, the application runs fine. (.NET framework 3.5, Windows 7 Ultimate x86, running in VirtualBox (virtual environment)). Using Process Explorer I've tried to find some hints as to what's going on. Showing a callstack in PE at some arbitrary point when the app hangs is shown at the bottom of this post. The one line that caught my eye was this: halacpi.dll!HalClearSoftwareInterrupt+0x355 I googled around a bit, looks like a number of people ran into this, but nobody had found the true cause of/solution to this problem. One that came close was mentioning a patch for .NET framework 1.1, but there seems no information on later framework versions: http://support.microsoft.com/kb/904705 Some more details from my customer seem to point in the direction of GraphicsPath, which is used quite intensively and I know this class does a fair bit of switching to native land and back (PInvoke, also mentioned in the patch above). We really need to get this one solved, so let me know what to do to get some developer support on this one. Thanks, - Wout ntkrnlpa.exe!KeSetEvent+0x2a1 ntkrnlpa.e

How to get message from Windows to actually running application in WPF?


I spend around few hours to find something about my issue on Internet. But I have no idea what to write in Google... :/
So I thought maybe it will be better to write here.
  I wrote an application which can save and open it own files. Then I added special registry key and now when I double-click on a file associated with my application, Windows (OS) opens my application and load the file. Most application work like this and thats OK.
But what I want to do?
I want my application to be opened just once. So when I double-click on a file the application will start running and load the first file. But when I double-click on second file (during my application is already running) windows will open second application. And I want to load this second file to already running application. What should I do??

PS - I am writing WPF application in Visual 2010 with .Net4.

ManagementEventWatcher stops raising EventArrived after running application several times


To monitor some application, I am using ManagementEventWatcher class and I have registered EventArrived event.

When I run application from .NET IDE it works fine. As I have not finished coding of other area on the same form, I have to run and close application serveral times. The problem is when I run application multiple times; for first few times EventArrived gets fired very well. but After some executions it doesnot get fired.

When I restart machine, again it starts working fine. Does any one have any idea?

SSRS 2008 - Fixed headers while scrolling - works fine for Matrix - but not for Table??!!


I have this feature working fine for matrix, but it does not work as expected for Table (Tablix).

I tried all over, and setting both check boxes in the 'Tablix Properties' dialog page 'Repeat header rows on each page' and 'Header should remain visible while scrolling' for both row header and column header, but none of it is working. Am I missing something?

In the properties table (F4) for text box of tablix, under 'Other' there is 'RepeatWith' - none / tablix: what is this used for? I tried this property also but I cannot get the headers fixed / visible while scrolling. I cannot get the 'column headers' repeat on each page of the report. Very frustrating...

Does anyone face similar issue? Can anyone help please? Do I need any update / download any fix? For now I have the following version installed for Visual Studio 2k8:
