• Visual Studio 2008 (Pre-release) Bizarre bahavior concerning identity tracking of entity objects versus query

  I am seeing some behavior that looks odd. It has to do with the identity tracking of entity objects versus querying the same object from the database. What I have found is that if I perform a DLINQ query, an entity's membership in the results set is determined by querying the actual database, but if that entity is already in the DataContext cache, the cached object is returned in the results set. This can be odd because the state of that entity in the database may be inconsistent with the state of the entity in the cache. As an example, I will query a specific customer, LONEP from Northwind. LONEP's region is OR. I can then change his country to United States in the entity object. It is USA in the database. Then, i will query all ...Show All

• .NET Development .NET Uri class - problem with built in unescaping.

  I am having a rather serious problem when trying to create a URI which contains escaped backslash characters. During construction, they are un-escaped and converted to forward slashes. For my application, it is necessary that they remain in their escaped form. The interesting part is that the Uri class only messes with the 'slash' characters, it properly leaves my other characters escaped. Example: literal is : http://192.168.127.33:54845/C:\MJPEG A.jpg It is necessary in my application to send the relative path literally. To accomplish this, I pass in the following escaped sequence to the Uri constructor: uri = new Uri(" http://192.168.127.33:54845/C%3A%5CMJPEG%20A.jpg "); note: %3A = ":" %5C = "\" %20 = " " Howeve ...Show All

• Visual Studio Team System Deploy w/o Compiling

  Okay, After a build and deployment to our assembly environment the build is tested. If it passes the tests in the Assembly env, it is moved up the System test1 env for more testing; from there it would go to System test2 and end-to-end testing ... Production. With each move to a new env I am basically doing a redeployment of the build to a the new env. This is a manual process b/c I cannot rebuild. Is there a way through MSBuild or some other tool to automate this redeployment I'll tell what would be ideal, to have a team build type for each redeployment. Where I would set a couple properties via the cmd-line or rsp file to tell it what build to redeploy. Thanks a million, BJHop Have a look here ht ...Show All

• Visual Studio Express Editions if statement

  Hi, Can you please let me know what is wrong with the following if statement I believe the following values should make the statement to show the messagebox.
