• Software Development for Windows Vista Manual Frame Capture using DirectShow

  In Vfw there there are three operations that one can use to capture frames one by one and store them to a single capture avi file. These operations are: WM_CAP_SINGLE_FRAME_OPEN WM_CAP_SINGLE_FRAME WM_CAP_SINGLE_FRAME_CLOSE So, between open and close operations we can issue WM_CAP_SINGLE_FRAME to capture multiple frames. Is there a way do do the same using DirectShow As far as i understand IMediaDet specs it doesn't help me because I want to store only choosen frames in a single avi file during a capture session. Any sugestions for my problem ...Show All

• Software Development for Windows Vista StateHistory is Null

  I'm looking at a StateMachineWorkflowInstance. I can see my currentstate and everything else except for the StateHistory. I've got both tracking and persistence turned on. Why would this property be null Is there something I'm missing I can reverse engineer the workflow history by looking at the activitytrackingrecords in the sqltrackingworkflowinstance but I'd prefer not to have to do that! I'm using a custom trackingservice, btw, if that helps. Thanks, John Have you loaded a tracking profile Did you check the tracking database to see if any events were logged It seems like you may have a profile issue. Take a look at the following tracking sample to get an idea about how to l ...Show All

• Visual C# "The parameter 'sectionGroupName' is invalid"

  I'm trying to create a dataset. I have my database connection set up correctly, but when I try to pull the table into the dataset designer, I get the following error message: Failed to merger object(s). The parameter 'sectionGroupName' is invalid. Parameter name: sectionGroupName. Also, when I try to open the dataset designer for an existing dataset (.xsd file) a blank box appears where the table should be. If I click on the blank box, I get the error message: Mouse click operation failed. Exception has been thrown by the target of an invocation. I've tried searching the KB for these errors but I can't find anything. Does anyone know what could be causing this and how I can fix it Thanks! -Dell I'm just taking a wil ...Show All

• SQL Server Scripting dependent objects

  Am I the only one to notice that SYSDEPENDS in SQL2000 is flakey in the extreme. Dependent objects created out of sequence generate omissions in the update of the sysdepends table. Come along later and create scripts to recreate the database structure via enterprise manager and the the dependent objects (udf's, views and Stored procs) and they are scripted in an order that generates errors. If you take the errors and trace the parent objects requesting the objects and create a ALTER script in Query Analyzer it fixes the SYSDEPENDS on one odject but screws other bits. I have experienced significant time input sorting out these dependencies scripting multiple databases in a multiclient enterprise development environment, where, for ...Show All

• Windows Forms Disabling small trangular glyphs in the row header

  Hello All How can I disable showing the small trangular glyphs in the row header which appears in the current row selected in the DataGridView control. Thanks in Advance Prash In Columns collection you can specify each columns SortMode to none, so no sorting and no glyph. If you want sorting and only disable glypth, i think you have to write your own class (but i dont know how) or may paint header in cell_painting like if (e.RowIndex < 0) { string headerText = ( string )e.Value; e.Graphics.DrawString(headerText, this .Font, Brushes .Black, e.CellBounds.X + 5, e.CellBounds.Y + 2); e.Handled = true ; return ; } ...Show All

  Hi, I'm trying to make my own content loader for a custom font file. I've got the custom file to compile using an importer that I wrote, and I can see the XNB file is generated as expected, but the content manager can't seem to find my ContentTypeReader.

• Windows Forms AxWebBrowser: Method 'Navigate' cannot be invoked at this time.

  I have a somewhat complicated problem, but it boils down to this: When calling Navigate() on an AxWebBrowser control, I get this error: "Method 'Navigate' cannot be invoked at this time." What exactly does this mean and how can I fix it [Note: I am using Visual C# - and I'm relatively new to it] Details: I have a custom tab control ( Magic TabControl ). At runtime, I add new tabs with an AxWebBrowser control in each one. The first one added works fine and I can call Navigate() successfully. The second one produces the error when calling Navigate(). If I use the same setup, except with the basic tab control (System.Windows.Forms.TabControl) I get no errors whatsoever. I conclude that it has something to do with the custom tab control an ...Show All

• SQL Server Is it recommendable?

  Dear folks, we've got old tables with triggers which reading data from systables and some stuff... I know that it's stupid way to gather info but.. So that, now, using Sql25k is recommendable to use INFORMATION_SCHEMA tables or betther, take data from sys views Thanks in advance and regards, Hi, For my information system tables in SQL 2005 are hidden and they are not accessible, even they cannot be queried, actually it's not a matter of rights, even you're a DBA with full rights you will not be able to utilize the system tables, so it's strongly recommended to use the INFORMATION_SCHEMA views ( over 230 views ) they offer a great deal of metadata, also it will be more efficent as they provided by MS itself, for SQL 2k I ...Show All

• SQL Server Error managing

  Hi everyone, When an error occured in a transaction and we can also create a message for this error ourself too by using @@error in order to print a message . However, I wonder that is it possible to really catch and handle the error For example, when error occured it makes the transaction terminated. So how can we prevent transaction from terminating Meanwhile, I also examine RAISERROR statement but it also does not prevent a transaction from terminating instead t only provide an additional message for the error. In other words, I mean that; In the following procedure, when the error occured we determine it and then write a message abour this error by using RAISER ...Show All

  Quick question about membership in the Creators Club. I have 3 profiles registered on my Xbox 360. If I enroll my profile (GamerTag) in the Creators Club and upload a game will all rest of the local profiles be able to play the game as well All three profiles are Gold level profiles. Thanks, Mike This seems a bit restrictive don't you think If I created a game for my kids to play, well..., basically they can't play it. Unless I log them in under my account or I purchase another Creators Club membership for each profile. What do others think about this Am I being a bit short sided here Don’t get me wrong, the Creators Club (in my opinion) is one of the biggest steps forward seen in the ind ...Show All
