• Software Development for Windows Vista Named Pipe Connection Problems

  I have a service that creates a named pipe for application programs to connect to and read from. Works fine on XP. On Vista, when the client attempts to CreateFile() to the named pipe, if the desired access is GENERIC_READ the CreateFile() returns a valid handle. If the desired access is GENERIC_READ | GENERIC_WRITE, the CreateFile() returns access denied. After CreateFile() I call SetNamedPipeHandleState() to set PIPE_READMODE_MESSAGE. In the case where I have a valid handle from CreateFile(), SetNamedPipeHandleState() returns access denied, presumably because I don't have GENERIC_WRITE set on the handle - the documentation for SetNamedPipeHandleState() says I need GENERIC_WRITE, so this is expected. As an experiment I changed th ...Show All

• SQL Server Overlay of textboxes are not rendering properly

  In the page header I have a rectangle that has 2 textboxes on the same line and both are the full length of the page. One textbox has text centered and the other has text right justified. When I render report in Studio or print it, the text appears on the same line and justified like I want, but when the report is rendered when I call the report by URL, the textboxes wrap, like it's taking the width of each textbox in account. Has anyone seen this Any suggestions on how to overlay text on the same line and the text keep their own individual characteristics I am having this problem too. I have a template with a standard heading including one image and 4 textboxes. The template includes a boolean parameter ...Show All

• SQL Server Date out of range?!

  Greetings! I have a data source that gets generated based on a variable with the following SQL : "select * from result where deletion_ind = 1 and when_deleted >= '" + (dt_str, 50, 1252) @[User::Last_Run_Date] + "'" But when I run my package I get an error message saying: The conversion of CHAR to DATETIME resulted in a DATETIME value out of range The Last_Run_Date variable is set to '2006-06-25 14:35:05.450' When I run the code in a QA session it works, but in the package it complains!

• SQL Server Does "Current time member" on the KPIs designer do anything?

  The "Current time member" on the KPIs designer is poorly documented and that's an understatement. Does it actually do anything or is it unfinished code Has anyone else come to the conclusion that KPIs in SSAS were never "finished" We've found numerous holes in the way KPIs have been implemented. I have moved some KPI:s, for a client, from ProClaritys KPI Builder, to SSAS2005 KPI:s. So far this have worked fine and we are able to show KPI:s in other tools than ProClarity. As an example the coming Excel 2007 release supports SSAS2005 KPI:s. These KPI:s can also be imported in to Business Scorecard manager/server. If you need additional functionality I recommend the Business Scorecard Server inste ...Show All

• Visual Studio 2008 (Pre-release) how to use Claim.CreateRoleClaim for a role with clientCredentialType=windows

  Hi, I'm using wshttpbinding with message clientcredentialType of windows. When I decorate my operation with: [ PrincipalPermission ( SecurityAction .Demand, Role = @"domain\role" )] this works. (although changes in active directory are only picked up after a reboot of my machine ). Now I'm building a more flexible system, which will look at the claims provided and will compare it to a claim of my own (like in com-430): Claim requiredClaim = Claim .CreateRoleClaim( "domain\role" ); However, when using a comparer like this: ClaimComparer comp = ClaimComparer .GetDefaultComparer( requiredClaim.ClaimType); in an iteration of the claims, it will not be found. The claimset provided is mostl ...Show All
