• Visual C++ command line arguments problem

  I'm having problems simply reading command line arguments into my program. Here is my simple program: #include "stdafx" #include <iostream> #include <fstream> #include <string> using namespace std; int _tmain(int argc, _TCHAR* argv[]) { cout << argv[0] << endl; cout << argv[1] << endl; cin.get(); return 0; } Despite giving the program a text file as a command line parameter all the program out puts is nonsense like: 003B6058 003E7234 Why is it not outputing the name of the program or the name of the file Can anyone tell me what is wrong Read http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=849851&SiteID=1 and see the linked pages. ...Show All

• Software Development for Windows Vista External Events, ThreadPool and WaitForIdle

  Hi, Given: stateMachineWorkfow, which waits for some external events that are being sent to it via ExternalDataExchangeService. The service code contains something like: public event EventHandler<ServiceEventArgs> FireEvent; void TestFireEvent { ThreadPool.QueueUserWorkItem(delegate { if (FireEvent != null) { FireEvent(this, args); } }); } where ServiceEventArgs have 'WaitForIdle' property set to 'true'. Such a code makes the workflow runtime to wait till the workflow becomes idle, before delivering the event. Therefore the thread in the thread pool may be waiting for quite a long time, because we can not be sure if the workflow will become idle fast enough. This leads to potential problems because t ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Xbox 360 Guides in XNA

  Hi there, I've been playing around with the framework and I have a little question for any MSFTies who can answer. On the Windows side of things, if we want to call up any useful built in functions of Windows like say the common dialog box colour picker (for say, a player's car paint job) or a MessageBox (you've reached the end of the demo!), we can still do so by calling in to the Windows.Forms namespace. On the Xbox 360 side though, any such UI we would have to recoded manually. However, as we all know, there are certain built in elements of UI on the 360 too in the form of the various Xbox Guide slide out panels. Currently, access to one of these does exist in XNA (The save Location guide for letting the user choose a Memor ...Show All

• .NET Development Problem with Windows service and C#.Net code

  Hi, I am facing one critical problem.I have created one Windows service. I am calling a function of C#.Net class file by using remoting , say ProcessRequest(); from that windows service. Now, while executing the function ProcessRequest() if exception occurs, it is handled in the function. After this I do not want to proceed further and control is returned back to the calling component, i.e. Windows service code. After returning back to windows service, control is going in to the catch block of windows service . To remove this problem, I used ‘Delegate’ to call function of C#.Net class file i.e.ProcessRequest(). When I tested this modified code on Windows XP, it is working fine, i.e. control is not going in to the catch block ...Show All

• Visual C# ( ), { } and [ ]??

  Hi, Can someone please provide a detailed explanation of ( ),  { } and [ ]  and when each one should be used I have some knowledge of what they mean as I see them used quite often in different parts of the code. Sometimes I see them used in a rather confusing way but because the compilers never complained I had to assume that they were used correctly. Is there a standard for using them   Thanks in advance Hi, yes, there are specific rules when to use which. () are used for conditionals (if, for, foreach), to specify the order of calculations and for casts. More info to be found here . [] are used for indexed objects (ArrayList[0] == first item in the arraylis ...Show All

• Visual Studio Visual Studio SP1 run successfully but it not installed

  Help... I'm running on Window 2000 SP4 my Visual Studio 2005 Professional Edition. I need to develop a Web Application and a week ago I installed th Web Application plug-in.

• .NET Development Puzzled about Linq

  Hi, I'm quite puzzled... In the last few months i've learned to use TableAdapters, DataTables and all the fancy stuff that's in .NET to "abstract" the database. However, it's still not perfect - as there is no total abstraction between the data structure and presentation layer - it does make creating DAL and BLL easier. Now I keep coming across (D)Linq which uses a totally different, in my opinion, way of accessing the database. Using DLinq, i think i will end up writing queries in the presentation/BLL layer again, instead of using the DAL tools such as TableAdapters. Of course, you can write the queries only in the DAL, but i wonder what's the use of the TableAdapters then The question is all the more urgent because i n ...Show All
