• Game Technologies: DirectX, XNA, XACT, etc. my first game - how?

  I'm VERY VERY new to directX. So I apologise for asking this question I have used directX once, managed directX, within my C# app but this was for audio related stuff and it was very cool. Firstly, hats off to the top jocks at MS DirectX team for providing us with all these technologies - thanks. Now, I am wanting to know how can I go about writing a VERY simple basic game - this game would be like a shoot 'em up style. Example: 1 spaceship shooting other incoming objects. That's all. I am wondering what is the best place/area to look at to get me started What do I do How do I create graphics (basic) how do I make the spaceship move from left to right using the arrow keys These types of questions I would like to know and w ...Show All

• Visual Studio Tools for Office Content control events are not hooked in.

  Hi everyone I created a word add-in project using vsto2 SE beta and add some code into the ThisAddIn.ThisAddIn_Startup method  for sinking and hooking content control events. I expected this program to work welll but it didn't. Actually running this add-in,  ContentControl events were hooked into properly but at the uncertain moment events weren't  hooked in at all.

• SQL Server DTS & .NET

  I have a simple DTS package that is being executed within a .Net application using the MS DTSPackage Object Library. Since I have the SQL Server 2000 desktop tools installed, the package executes with no problems, however, when another user tries to execute it, the following exception is thrown: Retrieving the COM class factory for component with CLSID {10020200-EB1C-11CF-AE6E-00AA004A34D5} failed due to the following error: 80040154 I've tried including all the DTS references, rather than just the Package object reference, and that didn't help. Thanks in advance for your help. THis is really frustrating. 0x80040154 is 'class not registered', i.e. DTS is not installed on this machine. Solut ...Show All

• Visual Studio Team System Access "Start Date" and "Finish Date" via TFS API

  Hi, I'm integrating access to TFS in one of our internal development tools. So far I have successfully connected to the TFS, retrieved a WorkItem etc. I was also able to modify the "Completed Work" field programmatically. How could I access "Start Date" and "Finish Date" Those fields seem not to be part of the Fields collection. I haven't found any samples. Any help would be appreciated. Regards Uwe I have done some additional testing: In CMMI it seems that only the "Task" WorkItem conntains the fields "Start Date" and "Finish Date". Project and Excel seem to be able to add those fields but I was unable to verify that. It didn't ...Show All

• Windows Forms Datagridview text

  Hi, I've got a datagridview with records that contain date and time values. When the user selects a specific row and clicks on the edit button, s/he must be able to edit only the record that s/he selected in another form. My problem is, time values do not display in textboxes, as they do in a datagridview. For e.g. time in datagridview displays as 09:00 AM but as 1899/12/30 09:00:00 AM in a textbox. The format in the datagridview is successful because it's databound and I don't want to bind the textboxes (because these values are meant for display only). See my code below: frmEditBooking.txtID.Text = dgvBooking.CurrentRow.DataBoundItem( "bookingID" ).ToString frmEditBooking.txtUserID.Text = dgvBooking.CurrentRow.DataBoun ...Show All

  Hi everybody, We were developed some Web-Services that run against SQL Server 2000 with SQLDataReader that executing Stored Procedures in the DB. Most of time (95%) everything is running well, but sometimes (when exactly, we don't know) the same WebService that worked 200 times, fail.

    I am working on cropping a part of the existing Bitmap image and test whether the cropped part is present  in another image or not.

Can anyone help me out of this Thanks I am working on mobile Phones applications. VSTO doesn't really come into picture here.

• Visual Studio Forcing order of swimlanes

  I have the following situation: A neural network consists of multiple layers (modelled using swimlanes.) There are three types of layers: Input, Hidden and Output layers. I'm basically done with the modelling, but want to restrict the order of these layers in the diagram: The order should always be fixed: Input, 0..n Hidden, Output. E.g. if the user adds more hidden layers, these should be inserted between the last hidden and the output layer. I've managed to arrange NestedChildShapes this way and have looked at the Anchoring, which are both the way I'd like the diagram to appear. However: On screen the newly added hidden layers always appear after the output layer. Any hints what I need to do to change this ordering scheme Thank ...Show All

• SQL Server Authentication across internet

  From what I have understood, Reporting Services could be configured to use Basic Authentication. In this way, a user can access a RS-server across the internet and he/she will be prompted for a valid username/password when trying to access. However, from what I can understand this username and password will be sent uncrypted over the Internet (from the client machine to the RS-server), right My problem is, I need to give access to users acress the internet to a RS-server. The users uses all kind of operating systems (Windows, Linux, MacOS tec). And the communication needs to be encrypted. How would you recommend me to implement security for this solution I guess some kind of "Forms authentication" will have to be used Bu ...Show All

It also shows up in the view "dbo.viewExecView". It does not appear in the new view that joins to "dbo.viewExecView".
