Operating systems have a concept called the "executable." An executable file is essentially a program that can run in the operating system. The standard convention in windows is to mark an executable file with the .exe extension.

Items Disappear from collection

So I have run into a serious problem that did not exist when I left work last week. I have items that are dissappearing from a collection as I iterate through it. I have a class called host which has a List<String> in it which has a list of Urls. There is only one way to get and remove urls, a property called NextUrl.

<br />
public string NextUrl<br />
{<br />
 get<br />
 {<br />
  string url;<br />
  lock (_urls)<br />
  {<br />
   url = _urls[0];<br />
   _urls.RemoveAt(0);<br />
   _lastTouched = DateTime.Now;  <br />
  }<br />
  return url;<br />
 }<br />
}

The loop is as follows

<br />
                foreach (Host h in currentList)<br />
                {<br />
                    if (h.Count > 0)<br />
                    {<br />
                        DownloadUrlAsync(h.NextUrl);<br />
                    }<br />
                }   <br />

currentList is a contains a List of hosts.

If I step though the code at both the if statement, the { and DownloadAsynucUrl items dissapear from the collection. I am not sure how this happens. By the time it gets to the NextUrl property there are no Urls left in the collection. When the program first hits the if statement there are 6. Has anyone seen anything like this? Am I crazy?

Thanks,

Steve

Open the project in Visual Studio 2005, and you will be presented with the migration wizard.

Do you mean that no .cs files have been added or modified?

That's right. Migration from VS 2003 to VS 2005 does not modify source code, as VS 2005 supoorts both new and old syntex. The migration is done through adding/changing a couple of project setting flags.

Stricktly speaking, only the VS 2003 project has been migrated and the source code hasn't.

I never encountered that. Confused | :confused:

Could you check what language your .NET 1.1 code was written in and if your VS2005 installation has support for that language?

BTW, I didn't say the following in your quote: Smile | :)

File Downloading - Help Please

Hi,

I have recetly moved from Java to .NET/C#.

I am trying to download a file from my test website and save it to disk on any client machine (this means getting access to each clients hard disk etc).

In java this required the use of applets etc...

I have so far not found the corresponding code in C#/.NET.

I am wanting to

(i) click a button in a web page on my website.
(ii) do some security checks before proceeding
(iii) stream the file(s) from the source directory on the website host machine
(iv) stream the file(s) to the client
(v) save the file(s) to the clients hard disk.
(vi) the original file may need to be zipped so the client side operation may require an automatic unzipping process

I know I could zip all the files and then add a link to my webpage that the user selects to download the file and then they manually unzip the relevant files but in some instances an automatic approach would be better.

Any help greatly appreciated.

I have also posted this to the C# board if this is the wrong discussion board.

I will keep searching.

Regards Andrew Mercer

How to maintain authentification for multiple http requests ? [modified]

Hi all,

Is there a way to maintain authentification if I had to send multiple requests ?

Here my current code:

HttpWebRequest webrequest = (HttpWebRequest)WebRequest.Create("http://.........");<br />
webrequest.Credentials = new NetworkCredential("....", "......");<br />
webresponse = (HttpWebResponse)webrequest.GetResponse();

For example, with MFC, I just create 1 HttpConnection and I can do any number of requests.

m_pHttpConnection = m_InternetSession.GetHttpConnection(strServer, nPort, strUserName, strPassword);

But may be internally, the login password is sent for every request?

I have a vb.net (.net 2.0) app that I installed. I know where the app is on my system, and I can run it from a batch file, but I can't seem to get the damn thing to run from within a non-.Net app. I've tried createprocess, and winexec, but nothing seems to work. I even tried to use createprocess to run cmd.exe with the batch file as a parameter, but that doesn't work either.

Does anyone have any clues?

I have a application built in .NET Framework 1.1. I have to migrate it to .NET framework 2.0.

Can anyone tell me how to go about this migration. I tried to open that application in VS-2005 but some files were not loaded in the IDE as a result of which I was unable to compile the application.
Kindly let me know how to go about the migration from 1.1 to 2.0

Thats a ASP.NET web application with VB as the code-behind. I got a suggestion earlier - to try and compile the application and then work-out the errors. But some files fail to load while the application is started with VS2005.
Can you please provide a workaround to this ?

Depending on how simple your web app. is you could be in for a tough time. Where I work one of my colleagues has been tasked with trying to upgrade our main application from 1.1 to 2.0 and so far it's taken several days and theres's still no light at the end of the tunnel!

However, there are one or two documents floating around which are supposed to give guidance on how to do it. Google on "upgrading asp.net to 2.0" or something like that.

The following code doesn't compile/work..
CNode* pNode;
pDataRow->Item["ptrNode"] = &pNode;
I don't know what this compile error means "error C2102: '&' requires l-value"
Also Access97 has a "number" data type, can it store a pointer???
