• Visual C++ How can I do asynchronous socket proramming in console application?

  I was trying with using WSAAsyncSelect , but it requires handle parameter of the window to which the message will be sent when an event occurs. So how can I get handle of a console application Or there is some other way to do asynchronous socket programming in console application. Thanks. The wait function returns WSA_WAIT_EVENT_0 if one of network events occurred during 1 second interval, i.e. the host is ready for reading or writing, or closed the socket. Otherwise it returns WSA_WAIT_TIMEOUT after 1 second. In order to determine which of events occurred, try WSAEnumNetworkEvents . If you need just to check the readiness without waiting, then specify zero timeout. Probably you can obtain more p ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Is it realistic to create one's own engine?

  I'm not new to programming, but I'm new to game programming and C#. I'm wondering to what extent it's realistic for someone to make their own 3D (or for that matter 2D) game engine. The two projects I have in mind for myself are a turn-based 2D war/strategy game, and a 3D adventure game in the manner of "Dreamfall". On the 2D side, I feel confident I could come up with a 2D interface on my own. I haven't done a lot here yet, but I did manage to whip up a little 2D hockey game without peeking at Bill Reiss's excellent 3D airhockey tutorial at http://xna101.spaces.live.com/ . I've even given my computer hockey opponent a very primitive AI. OK, my collision detection and physics aren't great, but I'm not sure how much I'll need either of ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. RenderTarget2D rendered with garbage all over it

  Hi I've got a 2D project where the world is rendered to a 1024x1024 RenderTarget2D texture, then that texture is drawn to the backbuffer. It works fine on my laptop. On my desktop, however, the RenderTarget2D texture is drawn with an overlay of garbage consisting partly of a frame of a DVD I was watching on the other display. I'm clearing the RenderTarget2D texture properly, and everything is drawn properly, but when this texture is drawn to the backbuffer it receives a nicely alpha blended amount of garbage that covers the entire texture. So I can see everything rendered perfectly on the RenderTarget2D texture, it's just covered with translucent garbage. Sorry, I can't get any shots now. When I get home from work I'll get right on that, a ...Show All

• Software Development for Windows Vista Replace text in XPS documents

  I'm trying to replace text in XPS documents and I've got nowhere. What we're trying to do is replace our old word templates that have bookmarks as placeholders; we use vb6 to replace the text where the bookmarks are. This is so users can create generic documents and merge them with our data from our database. We want to replace this as honestly the current solution isn't that good, but does work, so it's not all bad. I've created an XPS document with bookmarks, can't seem to figure out what makes a bookmark a bookmark in XPS. But really all we would need would be a placeholder like <Address> or <Name> or something and then replace that text with data. Can anyone help or at least point me in the right directi ...Show All

• Visual C++ wininet

  Hi I am trying to develop an internet app using wininet to download pages and then scan the data. The functions I am using are :- GetHttpConnection OpenRequest SendRequest It all works fine but I want to add a longer URL. For example at the moment my server is set to www.cnn.com . But I may want to go to a page like http://www.cnn.com/TECH/ or even something like http://money.cnn.com/ . So can anyone tell me how to do this. Thanks Jon Hi, if I understand the documentation you just pass the part after the server name as second parameter to OpenRequest. So pass e.g. "TECH/" as parameter. I think http:// is implicitly used, so I guess https:// is not possible. -- Sve ...Show All

• SQL Server Finding the Month with only Week and Year

  I'm having trouble figuring out how to do this, but I'm sure there must be a way. I have a table with a column for week number and another for year. I need to find out what month this particular week fell into. I realize that some weeks will cross over two months, so I'm fine with using either the first or last day of the week which could be turned to the day of the year. Any ideas how to get the month when you only have a week number and year to work with Also, I'm not the one who decided to save just a week and a year. I'm just one stuck trying to figure out how to use the data. :) You should do something like below instead which doesn't depend on the language settings or rely on specific date format ...Show All

• SQL Server Won't select rows with null field values

  I cannot in the life of me understand what goes wrong here... In a webapplication (C#.NET) I traced an inability to retrieve existing records to SQL Server, where I cannot do the same either. The problem is that in the parameterized query, some fields can be null, and thus when the corresponding fields in the database record are null also, they should be selected. But this won't happen for some reason. I wrote a test SQL statement that gives me the same bogus: DECLARE @institution int, @collection int, @serialnr int, @subnr nvarchar(50) SET @institution = 1 SET @collection = 1 SET @serialnr = 240 SET @subnr = NULL SELECT ID, Institution, Collection, SerialNumber, SubNumber, AccessionYear, Sagsnummer, DanekraeNr, TaxonIdentified, ...Show All

• .NET Development COM Interop w/ UrlMon interfaces

  Hello, I'm trying to create a temporary pluggable MIME filter in managed code. I've managed to convert the necessary interfaces into C# (with the various attributes, etc.) working from the idl (there's no tlb, and being inexperienced with COM, I couldn't figure out why midl wouldn't generate a tlb from the idl). I also implemented a few classes in C# implementing the proper interfaces for the MIME filter. I was able to register this filter for my process as a temporary filter as well. Now, all of this works - the functionality of my rudimentary filter is actually being performed and the WebBrowser control in my process has its input being filtered. Now, the problem: after a few passes through the filter (I think its when a GC collect pass ...Show All
