• Game Technologies: DirectX, XNA, XACT, etc. Pixel Manipulation of Textures

  Hi All I have created some 2d textures from bmp files and want to combine them in a new texture. I have been trying the surface getData()/setData() commands unsuccessfully. In fact if I get the data from a surface, modify only one pixel of it, and set the data back to the same surface I get a graduated pattern instead of just a pixel being modified Which is not really what I was expecting. Any help would be great, thanks. RF ayatollah wrote: I found exactly this Code in another Tutorial however the "Surface" method does not seem to exist in the Final XNA Gamestudio Express 1.0 ... Anybody know how the proper method to do this is now What I want to do is create a texture ...Show All

• .NET Development clone DataReader

  Hello all, I need to loop through DataReader two times, but the second time, I can't read it because it has no row. Here is my code Dim dr as DataReader 'Connect to database and retrieve rows of data Do While dr.Read() 'Process some reading rows of data Loop Do While dr.Read() 'This time the DataReader has no row here Loop So my question how can I process DataReader by using Read() again Do I have to clone DataReader If so how Thanks A datareader usually represents a forward only, read only cursor.

• Smart Device Development Web page or Mobile Application For A PDA

  hi there i have been tasked with developing my first application for a mobile device, in this case a PDA. we already have an ASP.NET website out there. however when i tried to access it via the PDA i noticed that the javascript was not working. also the page was scrunched up due to the small resolution. as i see it, i have 2 choices: - develop a subset of ASP.NET web pages for the PDA to cater for the smaller screen resolution. - develop a fully fledged mobile application for the PDA. my boss is keen to explore the web page scenario in order to save development time. however i am keen to find out what the pros and cons are of both methods from a more experienced PDA .NET developer. any advice much appreciated. its important i u ...Show All

• .NET Development How to use dataset designer to relate 2 different datasources and their databases?

  I have 2 databases on my sql server 2005 express. I want to combine both of these databases information within the dataset designer.

• Windows Live Developer Forums Contact list not showing in MSN Live

  Hey there, I have seen a few posts about this, but the fixes listed (in app data, deleting files & dirs) did not work for me. My contact list works fine in the old MSN, however when i install MSN Live it does not show anyone. I can try to add contacts and it shows them as offline (even though I know they are online). My friend has Live installed on his computer and it works fine, and we can sign in my ID on his computer and my list shows up. Since this is only on my computer, there must be something wrong with my settings but I have no idea what. I have no firewall or such thing. -please help I'm also having exactly the same problems.

• Smart Device Development Removing the Title Bar from the Form using Compact Framework

  Hi All, i was wondering if anyone knows of a way that I can remove the Title bar from the UI forms using C#. You used to be able to do this using Win32 dialog boxes, however I can't seem to find out how you can do it using managed code. Anyone know Thanks, Hi Rachad, What version of the compact framework are you using If you are using .NETCF2.0 the Maximized property of the form should work. I have found bugs with this though, as the OS controls the system bar and this sometimes gets in front somehow. I've had to live with this to some extent; I suppose I should check this behavior out with MS <g>. There are a couple of other options though and these are useful if you are not using .NETCF2.0: ...Show All

• Visual Studio Team System Uninstalling Evaluation version of Team Explorer

  Hi, I installed the evaluation edition of Team Explorer on my machine, and when I'd finished, I uninstalled it (through Add/Remove programs) The problem I have now is that although it does not appear inside VS on hte menus, it does appear as an installed element on the splash screen, and I get a blank form displayed when I start VS which appears to be the dialog that used to prompt me for a user name and password. (I had to specify these to connect the the TFS server because if network problems). Any ideas on what might have been left behind that could be causing the problem Cheers, Bill Thanks for the error report. So we can help investigate this further, can you tell us a bit more ...Show All

• Visual Studio Express Editions How to find missing numbers

  I am trying to figure out code to determine which numbers are missing from a column within a datagridview based on a number entered by the user. In other words, if the user enters 10 into a textbox and there are 3 rows of data in a datagridview that contain 2, 5, and 7 in a column named Number, then I need a string result to be "1 Or 3 Or 4 Or 6 Or 8 Or 9 Or 10". Can anyone help me I'm sure it has to involve For, Next statements and possibly some If, Then statements, but I can't follow the logic and put it to code. For an added challenge, The "numbers" in the column are actually strings, with the number 1 displayed as "001", the number 10 as "010", and the number 100 as "100". But, ...Show All

• Visual Studio Tools for Office HTML in Outlook meeting body

  First question: If I use the outlook object model included with VS2005, is it only going to work with clients that have office 2003 installed I'm using my code to create an appointment via a web app, and can't rely on any specific version installed. I found another way to create the file, so that isn't too much of an issue if so. But my second quesiton is: I'd like to create a link in the body, but when I add HTML, it just renders it all as text. Is there a property that i'm missing Here is the code that i'm currently using: Private Sub AddOutlookReminder() Dim icalendar As String = BuildApptItem() Response.ContentType = "html/x-vCalendar" Response.AppendHeader("content-disposition", &quo ...Show All

• SQL Server More details for: SSPI context / [DBNETLIB][ConnectionRead (recv()).] General network error

  Hello together, since over a week I've been looking to find out the reason for two error messages I get from our users and servers, unfortunately without success up to now. I really hope you can help me. We are using Win 2k servers with active directory and SQL Server 2000, clients are all Win XP with SP2. Versions of access are 2002 & 2003. The errors are userspecific and occur in both versions. The SQL-Servers are accessed with an adp-file in 2002-format. We have one usergroup which is member of specially many groups. This affects the size of their windows access token which becomes constantly larger. In order to enable those users to still access their mailboxes on our Exchange servers, the DWORD entry ...Show All

• Visual Basic What To Install From VB Installation CD To Let Users Run My Application And Not Enter VB

  The best way for me to do what I want to do is install on all PCs (using VB installation CD) the minimal requirements to run my application which uses VB 2005, ADO.NET to read/write to an Access database, and Crystal Reports. I ask you what, specifically, should I install on all these PCs from the VB 2005 installation CD After that the next thing I will do is I give each PC user a shortcut file (having a nice icon that says database on it) which runs the exact same executable on a shared drive. My application already has the capability to tell users if someone is already actually using the database via a warning message. The hope is that only one person will use the database at a time. There aren't many users so this sho ...Show All

• SQL Server SQL Native Client automatic failover only works when both servers are plugged in

  I have setup a database mirroring session with witness - MachineA is the principal, MachineB is the mirror, and MachineC is the witness. Each SQL Server instance is hosted on its own machine. The mirroring is working correctly. If I submit data to the database on MachineA, and then unplug the network cable on MachineA, MachineB automatically becomes the principal, and I can see the data that I originally submitted to MachineA on MachineB. All the settings are showing correctly in Management Studio. My issue is with the SQL Native Client and a front-end application that needs to make use of this database. I have setup my front-end application to use the ODBC client and specified the failover server in both the ODBC setup and the connecti ...Show All
