.NET Development To regex - or not to regex?
Hi, I have yet another regex query - this time regarding the retieval of a URL from HTML. I have a string called HTML, with a number of links on it. The format for these links is something like: <a href="/index/welcome.php action=one&section=27">one</a> Now, I only want the link which is called one (in the link text - so between the > and the </a>), and from that link I want everything between the " marks. Can anyone help me do this Thanks This pattern should work. \<a[^>]*\>([^<]*)\<\/a\> It is defined as: <a Any character not in ">" zero or more times > Capture Any character not in "<" ...Show All

Game Technologies: DirectX, XNA, XACT, etc. XNA with Windows Forms - Game does not stay active
I programmed my own FormsGraphicsComponent like this: public class FormsGraphicsComponent : IGraphicsDeviceService , IGraphicsDeviceManager , IDisposable { public FormsGraphicsComponent( Game game, IntPtr renderWindowHandle) { ... } ... } Then used a standard windows form as a base, placed a Panel on it, that I exposed as a property of the form. Starting with almost a standard game, I modified the main program to this: MainForm form = new MainForm (); using (MyGame game = new MyGame(form.RenderPanel)) { game.Begin(); form.Game = game; form.Show(); while (form.Created) { Application .DoEvents(); &nb ...Show All

Smart Device Development Deploying Mobile Applications using SMS
I would like to deploy a client application to mobile devices. I have heard its possible to embed a link in an SMS message that will permit the download of a client application.

Smart Device Development Technique to view large jpgs
What's the best way to view a high resolution jpg photo I tried the picturebox control in a form approach, and it won't work for high resolution photos because when the Bitmap class converts the jpg to a bmp, it's too huge for the device. I would like to scale it to the screen size (I scaled it before and so I know it will work), but I have a "chicken or the egg" problem. I have to convert it to a Bitmap first before I can scale it. Bitmap hiResBmp = new Bitmap("hi_res_photo.jpg"); //dies here Bitmap smallBmp = MyScaleImageMethod(hiResBmp) pictureBox.Image = (Image)smallBmp; Or is the only solution to pre-process the jpgs (make them smaller) before loading them on the device Thanks ...Show All

Architecture Efficient Image comparision and sending Image Difference
Scenario: Client Program needs to send Screen shot after every 100 milli seconds. Now i want to compare 1st sent screen shot with the next captured screen shot. I want to calculate the image difference and send only the difference betwwen the two screenshots to the server. and then the 2nd Screenshot will be genrated on the server. Conversion to byte array and then comparision is possible but that is very slow. I need an efficient method. Because speed is the concern overhere. regards I'm not too sure about the code, but it seems ok. Anyway, you can try encode the difference by some algorithm such as run length encoding, since most of the time the screenshot wouldn't have much difference, which ...Show All

Game Technologies: DirectX, XNA, XACT, etc. Math.Abs inner workings?
I'm trying to decide how to structure my code based on Math.Abs function. Does it just flip the signed bit to make the number positive Or does it check for a negative value and if found, multiply the number by -1 Ummm.. If it matters to you that much, why don't you just write your own :) I mean you can't change the function in the Math lib even if you found out. Best thing would be for you to profile your code and find which routine have the best performance. ...Show All

Windows Forms DLU vs Pixels
Hi, I'm reading some reference material I found on the net, they give a suggested distance for placing elements in the forms (example was a Dialog Box) for the apperance to look good and correct, the measurement they talk about is DLU (Dialog Box Units), and Visual Studio as far as I know handles pixels, is there a way to convert the units to DLU's or to be able to convert manually to the closest pixel range Example: 7 DLU = XXX Pixels or a formula to calculate the any given DLU to pixel and viceversa Any help would be appreciated. Thanks DLU's depend on the font used on the form. Quote from MSDN docs: " A DLU is based on the size of the dialog box font, normally 8-point MS Sans S ...Show All
Smart Device Development End Call Event
Hi, Is there a way for an application running on a smartphone (ex: SMT5600) to get a callback when a call ends I would like to write the code in C#, but if I need to I would be happy to use C++. Any advice would be appreciated. thanks, Jake You can do this using the State and Notification Broker APIs in Windows Mobile 5.0, but unfortunately there's no simple way to do this in earlier releases. You can probably find some sort of TAPI call that will do the trick, but you'll have to do it in C++ and it'll be messy. Neil ...Show All
