• SharePoint Products and Technologies Accessing a SQL Server table using sql authentication as opposed to windows authentication

  I have created a pivot table based on a sql server 2005 relational DB connection, with the userid and password stored in the ODC (sql server authentication). The ODC is in the data connection library (DCL) and is approved. I created an Excel sheet with a pivot table based on the ODC. I can refresh this pivot table in Excel 2005, and I have deployed the sheet to the documents library. When accessing the sheet via Excel Services Web access, it displays properly, but refuses to refresh, errorring with : "Unable to retrieve external data for the following connections: xxxxx The data sources may be unreachable, may not be responding, or may have denied you access. Verify that data refresh is enabled for the trusted file location and ...Show All

• Visual Studio 2008 (Pre-release) orcas alpha

  maybe it is not 100% linq related (I personaly think that it is ;p) on friday first public alpha of vs orcas has been relased (or is it vs2k5 on net4 steroids ) http://www.microsoft.com/downloads/details.aspx FamilyID=82243606-d16d-445c-8949-9ee8c10cda2e&DisplayLang=en aviable as vpc image. some info @ dowload page The Orcas CTP's are released with only the features that have migrated into the main source tree after having passed all their quality gates.  So, unlike the LINQ specific preview, you'll only see LINQ features trickling in to the official Orcas CTP's bit by bit.  We do plan to have most of what available in May's LINQ preview in the first beta, refined of course, and much more s ...Show All

• SQL Server Preview has data but no columns returned

  In my SSIS package, I connect to an external SQL server database. This external database supports a stored procedure that I need to execute to "retrieve data". So in my package, I set the DataAccess Mode property of my OLEDB datasource to "SQL Command" and I provide the command EXEC <proc_name> <Param>,<output_param>. (The proc has an output parameter). The preview shows all the columns and data, but somehow no columns are returned....so when I try to link this data source to a copy column task, I get an error saying the source does not have any columns...any idea why this could be happening. Thanks - Manmeet Unfortunately that didnt work too...this is what I did...I now have this variable that st ...Show All

• .NET Development Thread Memory consumption

  It seems that starting a managed Thread in .net 2.0 allocates 1MB of memory. I created a quick and dirty sample to reproduce this behaviour, it creates 100 threads and each thread sleeps for 10 seconds. Memory usage (while all threads are live), 100MB when compiled with the c++/cli or c# .net 2.0 compiler. Same code ported and compiled with VS.NET 2003 allocates just 3 MB. It has to be that I'm doing something wrong, can anybody put some light on this Srdjan // -------------100MB, cli/c++ .net 2.0 using namespace System; using namespace System::Threading; using namespace System::Diagnostics; ref class Work { public: static void DoWork() { ...Show All

• Visual C++ Problem with GetSaveFileName(&ofn)

  GetOpenFileName(&ofn) works great, but no matter what i try to save the file as with GetSaveFileName(&ofn), it takes the name CB. When i run it with the debugger, right before ofn.lpstrFile is used as a parameter in my file out function, it is supposedly the correct file path. Try one more adjustment – the ' & ' character before ofn : void InitOfnStruct(OPENFILENAME & ofn, . . . .) I hope it works now. ...Show All

• Visual C# Shutdown.exe problems

  Process shutdown = new Process(); shutdown.StartInfo.FileName = "C:/WINDOWS/System32/Shutdown.exe"; shutdown.StartInfo.Arguments = "-s -f -t 20 -m \\deruu"; shutdown.Start(); I can get it to log me out using argument -l only, but with that I only get a "Frozen" cmd window titled "Shutdown.exe" and nothing happens. Damn, I suspected it had something to do with that but figured C# would ignore it if it wasn't followed something valid.
