• Windows Search Technologies Do I need to create a new store?

  I'm working on an app that stores files in "docs & settings\...\app data" in a profile. I want to add search functionality to my app. I've added the path to the indexable paths in WDS (2.6.5) and the docs I'm interested in get indexed, but I don't really want the to be returned normally by desktop search so I'm not happy with that approach. I thought I may settle for using 'in:myfolder mykeyword' but as far as I can tell I cannot use a full path for 'in' and it doesn't search recursive subfolders (is that right ). so I'm thinking I'll have to create a store so I can do something like "WindowsSearch.exe /url search:store=myapp mykeyword". If that seems to be the thing to do, then I need to create a pro ...Show All

• Visual Studio Team System Setup cannot access Reporting Server

  Hi there, i'm trying to install the Team Foundation Server. When setup asked me to enter a user for the Report Server. I created a user TFSReport and added him to Administrator-group and all the sql-groups. I opened the Report-Server Configuration and configured it so that the TFSReport-User controls the service (works without any errors). Near to the end of the setup, i get the following error, that setup cannot access the SQL Report server. I should ensure that it is installed, that it runs and that i can access it. Any idea Thanks in advance, David I don't remember exactly which log it is, but you'll want to look in the usual places (c:\windows\, c:\windows\system32, and your profile's temp directory ...Show All

• Software Development for Windows Vista weird exception

  I am new to WWF and just trying to create a 'hello world' application in WWF, I am loosely following 'presenting Windows WorkFlow Foundation' beta edition.

• .NET Development Maximum UPD message size - WSAEMSGSIZE

  I am using multicast (i.e. UDP) to distribute very high volume market data around a network. For my particular architecture, it turns out that larger packet sizes are more efficient (yes, I know this is not usually the case). However, when I dial up the packet size, I start running into WSAEMSGSIZE errors (socket error code 10040). I am unable to find any documentation on how to determine what is the allowed packet size. It would be useful to know this in advance rather than trying to tweak the numbers until my app breaks. Can anyone provide any guidance on determining what value will trigger WSAEMSGSIZE and whether it can be configured directly. I've tried SET_SENDBUF and SET_RECVBUF, but these didn't seem to work very well. I think there ...Show All

• SQL Server Relationships and constraints across databases

  (I wasn't sure which forum to pos this in. Let me know if you think there is a better one.) I have an application that breaks down into two sets of data, Set A and Set B, for our purposes. Both Sets currently reside in the same database. Set A is a fairly static set of data, changing maybe once a week, if not less often. Set B is empty at first but it has a lot of dependencies to Set A. Items are chosen from Set A to fill Set B but never the otherway around. Here is the problem. We continue to copy the "master" database whenever a new customer signs up. The problem is, anytime we have to update data on Set A we have to do it across multiple databases. Set B is never copied as its customer owned. What I would like to do is c ...Show All

• Visual C# Best practice for an interruptable Worker Thread in C# 2.0

  I'm writing a DLL (no GUI involved) that exposes a couple of functions that control the execution of a long process. There will only ever be one client of the DLL at a time, and only one worker thread. For brevity's sake the two functions are: Start() - Starts the long process. Stop() - Stops the long process. Long process preforms resource cleanup. The long process does not have a completion point - it is expected to run until stopped. After the worker thread is spawned by the Start method, I want it to report back to the main thread that everything is up and running OK, or report any error that may have occurred. The Start method will return this status to the user. I'm sure I have a few options as to h ...Show All

To keep this "simple" let's assume the following: Common Library projects - each contain a number of projects that are intendeded to be used by multiple "Products" CommonProjectA CommonProjectB "Products" - These are the end products, and each use either A/B or A&B - Each can release together or at different times ProductA ProductB ProductC - "C" agregates and depends on Product A & B of a consistent release Each Product A , B and C each have their own solution file that includes the relavent projects from CommonProject ...Show All
