• Smart Device Development USB Port

  Please suggest me how can I write applications for USB and Irda drivers. How can I open the USB/Irda ports, and read/write to/from the ports. Hi, I don't know what exactly you want to do with IR and bluethooth, but I suppose that OBEX (Object Exchange) API will be sufficient. It is very well described in MSDN (and recomended) . But If you determined to 'open/close USB/Irda ports' you have to deal with Virtual COMs. About Bluethooth you have deal with Bluetooth Protocol Stack. (hint look in MSDN for Bluetooth Protocol Stack and PORTEMUPortParams structure to specify attributes for the virtual COM port).In case of IR Win Ce has IR stack. In both cases you have to deal with a lot of stuff as RFcom ...Show All

• SQL Server Files not creating on Win2003

  I have created a package which extracts data from a table and creates several files. This works fine on my PC (WinXP SP2), but when i deploy it to the server it doesn't work. I have also tried to create the package from scratch on the server as the administrator and it still has the same problem. Anyone have any ideas Sean, The package is deployed on a Windows 2003 Standard server, SQL Server 2005 Standard.

Is there anywhere else i can check for the correct permissions Thanks ...Show All

• Visual C# Closing a form before opening another

• SQL Server OLE DB Destination - Fast Load with Maximum Insert Commit Size

  I'm seeing some strange behavior from the OLE DB Destination when using the "fast load" access mode and setting the "Maximum insert commit size". When I do not set the "Rows per batch" or the "Maximum insert commit size", the package I'm working with inserts 123,070 rows using a single "insert bulk" statement. The data seems to flow through the pipeline until it gets to the OLE DB Destination and then I see a short pause. I'm assuming the pause is from the "insert bulk" statement handling all of the rows at once. When I set the "Rows per batch" option but leave the "Maximum insert commit size" alone, I generally see the same behavior -- a single "ins ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Draw a sprite with an aplha map

  Is it possible to draw sprite using another sprite as an alpha map As far as I've read the only way I can do this is by first using the DirectX Texture Tool to create a DDS file. Is it wise to be talking about sprites in XNA when it's really a Texture2D How do I access more blending options for the source and destination I don't know how to do what you're saying in code. But you don't need expensive software to make a gradient transparency image. You can do that using Gimp . It's a free image creation tool with fairly decent tutorials and support out there. Maybe that will work for you to get this effect you're going for. I'm not an exceptional artist or anything, but it's the imaging tool that I use for everything I do. Hope that ...Show All

• Visual Studio 2008 (Pre-release) Reading and Writing image "Rating" metadata

  I'm looking for a way to read and modify "Rating" metadata that Vista uses to rate image files. I'm able to read the rating although I noticed that the rating is written in several places in metadata... and I'm not sure which Vista is using... it looks like all of them are changed at the same time and are kept in sync... so do I have to modify all of them to keep them in sync /xmp/Rating / xmp/xap:Rating /app1/{uint=0}/{uint=18246} When I'm trying to modify the rating... nothing happens...

• Visual Studio Passing Parameters to Crystal Reports 10 using Visual Studio 2005

  I have been looking all over the place and I am looking for a way to generate a stand alone Crystal Report using a parameter passed from a form in Visual Studio 2005. I don't want the report to be attached to a reportviewer, I just want the report to be opened with the parameters being passed to it. How would I do such a thing I have been looking for the answer and I cannot find it. Hi I figured out what was wrong with my report. In fact I consider this a bug, since in the vs 2003 version I use the same code with no problems at all and it works. The problem is when I use this line of code this .oRpt.Database.Tables[ "spGetAllMaterialForReport;1" ].ApplyLogOnInfo(oTLI); w ...Show All

• Software Development for Windows Vista Huge humbnail backward compatability

  Vista supports huge thumbnails and so I've taken full advantage of it in my latest applications - they look amazing. However, on Windows 2000 they do not display at all. How can you include the old style icon within the new and tell Windows 2000 how to find them in the files Or am I just making the icons incorrectly Thanks, Triple-M I don't really understand. Are you talking about icon files in Explore or are you talking about having large icons show in your applicaction's list view I think you mean the first..... An icon file is an ico and can support multipule views. Use a icon editor and create different image views for your icon. What editor are you using to make your icons If you mean the latter ...Show All
