• Game Technologies: DirectX, XNA, XACT, etc. About formats and multisampling

  I'm checking currently supported DXGI format, what exactly is the difference between: - D3D10_FORMAT_SUPPORT_MULTISAMPLE_RENDERTARGET - D3D10_FORMAT_SUPPORT_MULTISAMPLE_RESOLVE What is the meaning of the following formats: - G8R8_G8B8_UNORM and R8G8_B8G8_UNORM How are coded the following formats: - R9G9B9E5_SHAREDEXP - R8G8B8A8_UNORM_SRGB - R11G11B10_FLOAT (number of bits of mantissa and exponent for 11 bits and 10 bits float).

• SQL Server Table Locking in Partitioning

  Hi, I have the following doubt about table locking\blocking in case of partitioning:- Say we have 5 partition on the table Employee on the key Joining_Date and when we run 5 select queries on each of the parition in parallel will there be locking on the table when the 1st query is running or all the 5 queries can run in parallel. Basically, I am trying to see if parallelism and partitioning can work in sync or there will be locking at the table level if I don't specify any query hints Any help in this regard is highly appreciated. Thanks, Ritesh SQL Server uses a dynamic locking strategy. So the locking might use rows or pages to begin with and get escalated to table locks depending ...Show All

• SQL Server DR: Replication vs. log shipping vs. clustering vs. database mirroring........

  Up to now we have gotten by without having any local DR copies of servers (if a sql server goes down we are usually able to get it back in less than 3 hours). But I want more now. I want to trim the "down" window to no more than 5 or 10 minutes. (Immedate failover would be nice but is not an essential requirement. The essential requirement is to loose no data!) I have a spec of knowledge in these areas: SQL 2005 Clustering (requires approved hardware, quorum disk, etc. involved) SQL 2005 Replicaiton SQL 2005 Log Shipping. SQL 2005 Database mirroring. ( needs three servers) Which approach do you think is the most straightforward, sparing of hardware, yet reliable way to get us back up and running after a sq ...Show All

• Visual Studio Tools for Office Installing VSTO - Service Pack 1 required

  I cannot install VSTO (full boxed version, not downloaded) as it says I must have Service Pack 1 for office installed. My office installation has SP2 applied. I cannot install SP1 as it recognises SP2 is installed, but VSTO still won't install. SP2 is not available in my add remove programs list, as I would temporarily uninstall it to get around the problem. Any suggestions please Thanks, Laura. Hello, This error message often means that you have an unsupported version of Office installed, such as Office 2003 Standard. VSTO 2005 requires that you have Office Professional installed, or a standalone version of Word or Excel. The reason for this requirement is that VSTO 2005 takes advantage of f ...Show All
