• .NET Development Extracting data from TCP/IP and UDP network packets

  I am working a personal project that involves sending numerical data from one computer to another. The UDPClient and IPEndPoint working together can only receive an array of bytes. Converting from bytes to integers is a pain, to say nothing of what I imagine for converting to floats. Some details are discussed in a C# thread found here: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=1062358&SiteID=1 It seems to me that with all the communications going on, there are standard methods of extracting various types of data from network packets. I have been unable to find them. Question: How do I extract 16, 32, and 64 bit integers and various floating point values from network packets For stream based sockets (ie. TCP) ...Show All

• .NET Development Problem with calculated column - does not refresh automatically

  Hi I have three tables tbl_customer_visit (master), tbl_customer_visit_parts (detail) and tbl_customer_visit_services (detail). That have 1-many relations using customer_visit_id column in each table. I am using calculated columns in both the tables as following: tbl_customer_visit_parts and tbl_customer_visit_services have calculated columns for calculating the total cost for each part sold and service given for a given visit. then I have aggregate calculated columns in those tables to calculate the total costs for each table for a given visit. Then I have calculated column in tbl_customer_visit to take the totals from the detail tables (respective calculated columns) and give me the total amount due for that customer visit. NOW, the prob ...Show All

• Windows Forms How to have no image for some nodes in a TreeView with an ImageList?

  Is it possible to set some nodes within a treeview to have no image My treeview is bound to an underlying imagelist. I know that you can hack this by adding some sort of blank space image, but the imagelist constrains this to a certain size so you're left with a big space -- not ideal. I don't believe this is possible. The TreeNode inherit their imageList from the underlying TreeView so there is no way to decide on a node by node basis whether or not and images should be attempted to be drawn. You can set the ImageKey to null and there won't be an image drawn, but as you pointed out there will be the extra space inserted. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. The XNA Framework and DirectX

  Hi! Do I need to at any time learn DirectX when working with the XNA Framework In other words does the XNA Framework provide everything that DirectX provides, but without writing a single line of DirectX code Thanks, O. It depends on how deeply you are diving in the programming. All of us are really happy without writing any line of the DirectX code (except MS boys). The MS DirectX supplies a set of high-level APIs to access a hardware things. Writing an  application used native DirectX in full strength is not a trivial task. The managed DirectX for managed languages (like C#) is a step toward the less painful coding and the XNA framework is just the next step. Because managed languages are relativel ...Show All

• Visual C# Expedite the Build Process

  I have a solution with a large number of projects (including a client app, server app, some utility DLLs, some custom development tools, and some DLLs that act as plug-ins for the main applications).  All of them are C#.  The time it takes to rebuild even after making a small change in one code file is significant.  Even though it only compiles one of the projects, it lists each project in the output pane and spends several seconds 'building' it (which doesn't seem to do anything).  My best guess is that its scanning the files of that project to determine if anything has changed and needs to be rebuilt. If it helps, the project has 32 projects with 507 code files in total (although the distribution is very uneve ...Show All

• Visual Studio 2008 (Pre-release) Will WPF *EVER* work under W2K?

  I am keen to develop my next wave of development using the WPF. Thankfully it's a small project for internal use so it will be a good chance to try WPF out. The issue is there are two machines that run Windows 2000 AS. In the long term they will need this app on these machines, but in the short term (next 9-12 months) it's not an issue. Will there ever be a SP/FW release for W2K that will at least all WPF apps to run even if none of the WPF visuals are viewable by the user If not, does this mean that I'll have to develop two UI's for the app If so it's a big thumbs down and I doubt my company will even move from .NET 2.0/WinForms I wouldn't count on WPF for Windows 2000 ever becoming available - the OS is already in extended s ...Show All

• Visual C++ Different behaviour of MainFrame with classic and XP styles!

  In my windows profile Windows Classic style is set. My application has no scroll control here. But when it is run on computers with XP style windows, it gets a big vertical scroll to move my View up/down. I really don't want no scrollbar on my application. First thing I did was to set FALSE parameter in View's InitInstance here:  GetParentFrame()->RecalcLayout(FALSE);  ResizeParentToFit(); ... but, it did nothing to remove my unwanted scroll! Then I tried this piece of code:  CRect r;  GetClientRect(r);  SetScaleToFitSize(CSize(r.right, r.bottom));   .. and that removes the scroll, but now left side of the mainframe is empty, and there is just about enough space left ...Show All
