context switch deadlock

Posted By:      Posted Date: October 06, 2010    Points: 0   Category :Windows Application

I moved a windows forms app from an xp machine to win7/64

In vs I have the build set to x86

I get this error now.

contextswitch deadlock was detected

The CLR has been unable to transition from COM context 0x525b118 to COM context 0x525b288 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations.


This error occurs while trying to read/write to an access database.

OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\\ServerName\AccessDBS\ERTS\erdata.mdb");

I don't create any threads.

Creating Sites/Lists/List Items under Current User Context in SharePoint By Using SPUserToken

Usually we do this by performing the action under RunWithElevatedPrivileges method and updating the listitem using SPListItem.SystemUpdate() method (see here). but this approach has its own flaws like (RunWithElevatedPrivileges will run under system account, we cannot use SystemUpdate for SPSite,SPWeb,SPList, since it runs under system we will "CreatedBy" by as SystemAccount).

Cutting Edge: Context-Sensitive PictureBox Controls


Great ideas are timeless. A long time ago in Microsoft Systems Journal Paul DiLascia demonstrated a neat trick to display context-sensitive tooltips floating over pictures. As the user moved the mouse over the picture, the tooltip control updated its text to reflect the name of the pointed figure.

Although the context menu is a common element of most desktop applications, it is still fairly uncommon in Web application names because it doesn't map well to a server-based technology like ASP. NET.

How to switch between HTTP and HTTPS in ASP.NET MVC2


ASP.NET MVC2 has the new RequireHttpsAttribute that you can use to decorate any action to force any non-secure request to come through HTTPS (SSL).  It can be used as simply as this:

        public ActionResult LogOn()

Now any request to the LogOn action that is not over HTTPS will automatically be redirected back to itself over HTTPS.  This is very useful and easy to implement.

Unfortunately though, once the scheme is changed to HTTPS, all following requests will also be under HTTPS, which is not necessarily what you want.  In most cases you do not need all requests to your site to be secure but only certain ones such as the logon page or pages that accept credit card information. 

To handle this you can override the Controller.OnAuthorization method.  From within this method, you can check to see if the RequireHttps attribute is set on the Controller Action by searching the Attributes collection of the ActionDescriptor object. If the RequireHttpsAttribute is not set AND the request is under SSL, then return a redirect result to the HTTP (no

Switch views when opening a form depending on submit locations?



I would like to know it was possible to switch views when opening a form depending on where the form has been submitted.

I am submitting my form to library A and library B and want to be able to open it in view 1 in library A and in view 2 in library B.

Is there a way to set some url conditions in the open behavior rules?

Thanks a lot!

Hey guys,

I've got a literal control to display the username of the user logged into our companies intranet system, originally I had a LoginName control but couldn't get strip to remove the domain from the username (as the format is domainname\username) so I'm trying it this way.

    protected void Page_Load(object sender, System.EventArgs e)
        string[] Parts = User.Identity.Name.Split("\\");

        if (Parts.Length == 2)
            loginName.Text = Parts[1];
            loginName.Text = User.Identity.Name;
