• Visual C# How to open a web browser from a Windows App?

  Could someone please tell me how to open a web browser by pressing a button on a Windows App that goes to a specific website Many thanks Peter Ritchie wrote: Ken, there's all sorts of reasons why you may want to simply open IE (or the default browser) for a URL. For example, you may want to maintain a global history, or want to use global cookies, you want to use an IE toolbar, or you may be deploying to an environment where most applications are blocked from accessing the Internet. Actually, I'm wrong with the global history, it turns out if you visit a site in a WebBrowser control that site appears in the history list in IE... But, cookies are not shared between IE and a WebBrowser control. I ...Show All

• SQL Server T-SQL to Find Differences Between Two Tables

  Hello, I have got two tables 05FS and 06FS. I came up with a pretty straightforward query that is going to look at two tables and figure out which students changed their academic programs in 06FS semester. A query looks like something like that: SELECT * FROM 06FS a INNER JOIN 05FS b ON a.Studentid = b.Studentid WHERE a.AcadProgram <> b.AcadProgram . The problem with this query is that I also get students who have more than one academic program such as studentid: 1, and 3 and didn't change their academic program(s). Is there a way to weed out those students whose academic program didn't change and they have more than one academic program Any ideas are greatly appreciated! Data: Table 06FS ...Show All

• Visual Studio Express Editions how do we update our program?

• Game Technologies: DirectX, XNA, XACT, etc. Heightmap-line intersection

  I am making a little FPS game in directx. I am using a heightmap with clipmap DLOD (i think), and perlin noise-based heightmap generating. So. this is an FPS, and I need to determine, if I shoot, where does the bullet hit the ground. The gun is a machinegun, so 10 shoots per seconds and the shoot have to be evaluated in 1 frame. Now, I dont really know how to program this, because I cant test the bullet height 1000 times, because perlin is really slow. I have some generated heightmaps, updating on-the fly, so I could use them but I dont know how. Make the same triangles, and do a ray-test, or there is a better solution Mi heightmap is kind of like this: (maybe image is not visible) I can extract the data, but the density you ...Show All

• Visual C++ This application has failed to start because the application configuration is incorrect

  Re: This application has failed to start because the application configuration is incorrect I have built a small console application (the .exe is 17k) that I created in Visual C++ 2005 Express. I want to share it with 10-20 users working on XP platforms. It processes data using file i/o, thats all. However, I have found that on some machines it does not execute. I get the error message in the subject above. I figured out using Dependency Walker ( www.dependencywalker.com ) that my application requires the following: KERNEL32.DLL MSVCP80.DLL MSVCR80.DLL MSVCRT.DLL NTDLL.DLL The machine that my application did not execute on was missing MSVCP80.DLL and MSVCR ...Show All

  hey all i am using visual studio express and i was wondering if it was possible to creat dll files. i am putting a hook procedure in it. if it is please tell me thanx. Yes it is.

• Visual C++ WinApp() issue.

  Hello! The issue is: As we know, only one instance of 'WinApp() ' can be created in a project. for eg , name of my project is 'Universal Loader', and hence the class 'CUniversalLoaderApp' is created by default. An instance of this class is also created. This instance used in program to access the dialog class' members. I have created a reference of the 'CUniversalLoaderDlg' class , so that the Dialog class can be accessed by other classes.

• Windows Live Developer Forums map.GetRoute flags and numbers

  Hello everyone, I found map.DeleteAllPushpins(); removes the flags and numbers on the route path, is there any way I can prevent it Yuki Thanks John , I call map.DeleteAllPushpins(); on the attach event onendzoom, as map.GetRoute zoom to the route, the pins on the route are deleted when map is zooming to the route. And I have a lot of other pins, I cant keeptrack of each of them and delete them one by one .. because it'll slow down a lot. And I also found that with map.DeleteAllPushpins(); onendzoom, if the view needs to zoom to show the route .. then the turning points are removed .. but if the view is good to show route .. then the pins are looking good .. but when you do map.DeleteRoute();, the turnin ...Show All
