I already see the transparencekey and other properties , including the background color , but no results . Thank you Tiago After further investigation it would appear that the problem is in some way ...Show All

• SQL Server Matrix grouping/visibility

  I have tried several combinations, but I can't quite figure out the solution to this one. I have a matrix set up that is giving me the results I want, but I need to do a conditional visibility and still have what I need. I have a column that is filled with operation numbers and a row that is filled with item numbers. The detail is for work centers and it shows where each of them fall in the grid. I need to say to show all work centers that apply where the workcenter parameter matches. I was able to filter and say only show me this workcenter, but I want to show just those, but then if this workcenter would show up, show me the rest.

• Gadgets location.reload(true) kills the System object?

  I stuck a reload button in my gadget so I could easily refresh it to see the effects of changing something in the code. The onclick handler for the button is onclick="window.location.reload(true)". This does in fact reload the HTML and JS. But it seems to also kill the System object hierarchy. The code "Display.innerText = System.Gadget.name;" works the first time the gadget is added to the sidebar. Then I click my reload button and I get an error trying to access the System object. If I wrap the call in a try/catch and look at the error, it says "'System' is undefined". If I then close the gadget and re-add it to the sidebar, the System object comes back. I'm running the final version of Vista Ultimate ...Show All

• SQL Server merge replication - how can I synch

  we have a merg replication running in three regions UK,USA and AU my question is in one of our test environment testers managed to get a few tables out of synch while the replication is out. we have re-established the replication since then and it worked fine untill they try to update records from those out of synch tables. as usual we get conflicts. we don't really know how many tables are out of synch either. we have about 500 tables. is there a way to synch tables from with in the merge replication You can use the tablediff.exe tool to diff all 500 tables if that's feasible for you. To help reduce conflicts, you can also partition the data so each region has a subset of the data, e ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Creating and rendering a YV12 Texture

  Hi all, I'm using Direct3d + C# I want to do 2 things: 1) Create a YV12 texture. 2)render a YV12 information on it. choclate for the man who helps me :) If your card supports that texture format as a render target, then it's pretty straightforward. Just create the texture and bind it as a render target, then start rendering over it. However, I've never heard of YUV render-target support on PC before. If you have YUV support but not render-target support for YUV format, then you can use D3DXLoadSurfaceFromSurface() to transfer and convert rendered surfaces to your YUV surface, but it's not gonna be a real-time solution though... ...Show All

• Software Development for Windows Vista ASF writing to memory

  Hello I have a DirectShow app that uses the ASF writer to capture video from a webcam and write it to a file. I was wondering if there is way to write the data to a memory buffer instead of a file. My application will upload the file, so I will be happy not to use the file system. Thanks Ran. Hi and thanks for replying. You are right, I can use a frame grabber but then I will loose the ASF compression. The FS is not my bottleneck from a performance point of view. The reason I was thinking about memory is that I want to deploy my application using ClickOnce. I know that I can ask for FS permissions on a ClickOnce app, but since my videos are short and I want to upload them, it would be be ...Show All
