• Audio and Video Development MFCopyImage

  hi all when copying a YUV (nv12) sample from src to dest using MFCopyImage, for some reason it turns out to be greyscale even though though the original image has color. The UV bytes are not being set properly...anyone else have this issue This sounds like it copied only the Y plane. You might have to make separate calls to copy the U and V planes. (You'll need to do some pointer arithmetic.) I'll do some research and follow up. ---------------------------------------------------------------------------- Mike Wasson, SDK Documentation This posting is provided "AS IS" with no warranties, and confers no rights.

• Visual Studio Express Editions Qns on SQL 2005 EE, use with C# 2005 EE.

  Hi, got qns here regarding SQL database. Can my program with SQL database run correctly on another com using win xp home edition, with only C# 2005 EE installed Is it compulsory for every table in a database to have a primary key Can I extract a data from a specific cell in a database table(click button get data) How do I go about doing it (the simplest n straight forward method) Many Thanks in advance. sure :-) ok, the way the SqlDataReader works is, when you do a while (reader.Read()), this means while there is data...meaning, it will go through each row of data until there is no more data left to be read. so what i mean by the current row is the position that the reader is in. Does that make better sen ...Show All

• Visual Basic VB6 get function in VB.net

  Instead of using the get function in VB6, what would i use in VB.NET Perhaps if you state what your trying to do rather than translate the vb 6 code, there'd be a better .Net answer. But to answer your last question, #1 is the "filehandle" to the file you opened. ...Show All

• Visual Basic Hoe to handle multiple pages of graphics in VS2005

  Hi, I'm working on a graphics program which permits the user to select a drawing from a table, add required dimensions and other information, save the data in Sql tables, then produce a PDF file, and/or print out the page. Usually only one page is required with each page having a max of 6 drawings, however, on occasions there may be more than six, so a number of pages would be needed. So far I have reached the point where I am satisfied with the result, if drawings are <= 6, however, I am completely at a loss as to how to handle multiple pages. At present I am using the Paint Event to allow the user to see the result prior to saving or printing. However the print out takes about 15 seconds. Using Print Page Event, I believe ...Show All

I have VS05 Pro and SQL 05 developer, and they wont 'talk' to each other..isnt this stupid I tried to drop a createUserWizard from the toolbar, and just tried to run it, but it errors out when you try to create a user because it doesnt recognize sql 05 developer. the aspnetdb.mdf does not get created. is there a way around this more importantly, how do i get vs 05 to be able to directly create a db on sql 05 developer by adding a new db in the app_data folder VS2005 talks with all versions of SQL.

  Does anyone have an example of how to register an automation server in the ROT (Runtime Object Table) using IRunningObjectTable.Register and how to revoke it using IRunningObjectTable.Revoke Thanks, I've made some progress on this, but I've run into an obstacle I haven't found a solution for.

    Hello. For my application I have created an satellite assembly for a cultural reference, for example "es" or "de". The point is that mentioned assembly it does not have assigned the cultural reference for which was destined.
