• Windows Forms Full-Trust and Internet Zone Workarounds?

  Hi all, My application requires full trust, but it's just a freeware application that I want anyone to be able to install from my web site. At this point the only way to install it from my site is to add the site to your "Trusted Sites" in IE. This, obviously, is less than ideal for Joe User. Is there any way we can get around this Could I, for example, allow them to download a copy of the deployment files and run them from a local folder, then ...Show All

• Visual C# Advice needed please - How to display an image from a file quickly?

  I have a project that displays DPX files (an image file format common in digital film) in a PictureBox on a form.  It works but takes several seconds to display a typical image that is 2048x 1556 pixels.  Not so bad but .NET can display a similarly sized TIFF file in under a second. My display routine is primitive it just reads each 32 bit word from the file, unpacks the three 10 bit RGB values to 8 bits and finally sets the pixel valu ...Show All

• SQL Server File..Save Copy of <package file> As... not available

  According to the help for SSIS, one method of deploying an SSIS package to a SQL Server,  http://msdn2.microsoft.com/en-us/library/ms137565.aspx, is to use the File...Save a Copy of <package file> as... menu option.  I don't have that menu option at all.  And yes, the package is in focus.  My save menu options are simply; Save Selected, Save <package file> As... and Save All.

• Software Development for Windows Vista Statemashine workflow - Set State

  Is it possible for a state mashine workflow to have multiple states at the same time Hey Jon, I'm doing exactly this - with Cancel/OnHold/Pause etc. as being Events part of the parent state. From my understanding and what I've noticed is that in the State machine, there is only one 'Active State' - you can enumerate up the 'control tree' to find 'outer states' When the WF is sitting there waiting for an Event, we would like to kno ...Show All

• .NET Development Activator.GetObject and client-activated object mutually exclusive?

  Hi all, From reading the documentation and articles, it appears that when the remotable type is configured as a client-activated type, Activator.GetObject cannot be used. I tried creating an instance of a client-activated remote object using Activator.GetObject. I started from a working implementation of a Singleton to a client-activated type. I can get a proxy, but every call to a method on the proxy results in a "Requested Service not found" e ...Show All

• SQL Server Missing image in PDF Export version

  I have an ASP.NET application that passes stored procedure params and generates a dynamic report with one or more Image controls. The image paths are created with absolute references to their locations in a separate web directory, the one that the .NET app calls the report from. So the stored proc returns a string similar to http://mysite.com/myimage.jpg , and with an expression I wrote in the report designer, I assign this to the Image contr ...Show All

• Visual Studio 2008 (Pre-release) FindResource is throwing an exception

  The documentation says that FrameworkElement.FindResource will return null if the resource is not found.  But if I search for a style that doesn't exist, I am getting an exception thrown: ResourceReferenceKeyNotFoundException.  This is a huge performance drag in this particular application, where I look for a named style that is usually not present to see if the default style has been overridden. I don't see any "HasResource" or "TryFi ...Show All

• Visual Studio Express Editions Confused about method returns and params

  Howdy folks, Newbie comin' through... I'm confused about when a method is returning a value. I'm also confused about when a method is taking in a parameter or passing out a parameter. I understand that when a method name is preceeded by the "void" key word, it is not returning anything. However, when a method is preceeded by the keywords "string", "int", etc. it is returning a value of that type. my ques ...Show All
