Express Edition 2005 and VC++6

Hi every body,

Do you know if I want to keep both Express Edition 2005 and VC++6

then mybe the best way would be:

--name VC++6.0 cpp files with notepad

-- and then, ? does the VC++ Express Edition 2005 gives a different extension for cpp files?

==> then both plateforms can be used separately with no problems?

Thanks for any feedback!

Regards

The project files are different: VC6 uses dsw and dsp files and VC Express uses vcproj files (I think). So, you can use two different projects with the same source files.

well in fact no,

I tried yesterday but all the cpp files from VC6 projects where automatically renamed with Expres Edition logo and no way to recover my projects in VC++ 6....Until I unintalled Express edition 2005.

But..... if you mangage *.cpp files, how to keep them? in notepad? wordpad?
or just used developper VC++6.0?

Same question with Express Edition 2005?

thanks a lot.

.cpp and .h files are just plain text files (only the extension changes). So, you can still use them in VC6 even you install VC Express. What can happen is that you change things in the file and these changes are not supported by the VC6 compiler.

Don't convert your project. Instead create a new project and add the files manually. This way you will keep your VC6 project intact and you can still work on it.

tss, you are confusing between extension and explorer registered program to use this type of file. simply right click on the workspace file, ,select "open with..." and choose "developer studio" (visual studio 6).

to change the icons, open an explorer, select Tools > Folder Options... > File types tab...
there, reach the type you waznt to modify and click "Advanced" button.

yes, so you suggest that:

1) Vc ++ 6.0 I change properties for txt files ?

2) and for VC express edition 2005, I leave as it comes?

However, *.h files remain unchanged in the original format of creation,

Thanks a lot for your kindness,

Hello !
I need to find a library that implement the "probability error function" of a gaussian distribution. Basically, I need to retrieve the probability for a certain value of X (integration under the curve until a certain X value).

Does anybody knows where I can find that ?
Thanks

I recently read about QuantLib. It has some statistics library functions. I have not tried it yet, so I can't say for sure if it has what you need.

If you have access to Matlab type edit erf, or edit erfcore
and you will get the right code to implement the needed function(s) by yourself.
It looks quite easy.

Hope this helps

There are a few ways to do that.
1- Keep the main window hidden until the time to show. Using the Timer.
2- Keep another small application running (hidden) to run the main program. (using timer, or thread, etc).
3- Install a service that runs a thread, which checks the system time after certain Sleep() intervals. (Could create problems, while reading the registry etc).
4- Use some form of the task scheduler.
5- Some other way.

this is this.

Help with Client Socket Reconnect

NYTSX14-Mar-06 1:10

14-Mar-06 1:10

I have a client application that works fine provided that the user hits the connect/disconnect button. If the connection gets severed, my application will detect this and notify the user and allow them to reconnect by hitting the connect/disconnect button.

I have a requirement to have my application reconnect automatically, which will be used on an un-manned test later on.

I have one class that inherits from CAsyncSocket and a class for the dialog that contains the GUI/data that needs to be sent to the server. I have been trying to use this code:

int error = pSocket->Send( (char*)&CServerMsg, sizeof( CServerMsg));

// Check to see if the data was sent out OK
// If it wasn't, check to see the error
if(error == SOCKET_ERROR )
{
   // Reconnect to the server
      m_pMainApp = ::AfxGetApp();
      CMainDlg* dlg;
      dlg = (CMainDlg *) m_pMainApp->GetMainWnd();
		
      dlg->m_ConnectButton.SetCheck(TRUE);
      dlg->OnConnectButton();
}

but I keep getting an error that causes my app to die. I stepped through and it dies on the socket Create() method in my OnConnectButton, which is the same method I call when the user hits the connect button. It then throws me to the method
void* CMapPtrToPtr::GetValueAt(void* key) const

When I do a GetLastError(), I get the error code 10038 which says I am performing a socket operation on a non-socket.

The strange thing is that the send works perfectly fine if the server doesn't go down and I am connected to the server the entire time.

Please help, this has been driving me crazy for 3 days! WTF | :WTF:

Thanks!

I think the error would come depending on how you are calling the Send method. Do you use a thread, or a timer etc?
My suggestion would be to call the function using PostMessage(...). Like:
PostMessage(WM_COMMAND,MAKEWPARAM(IDC_BUTTON1,0),0);
(If it is sent from the dialog's thread.)
Where the code for Send is written in the Button1's press event.

this is this.

Two suggestions:

- create a socket only once and call Close();Connect() in your OnConnectButton() method. I am using my own network class, but I think to remember that am instance of CAsyncSocket needs to be closed before it can be reopened again.

- consider making your reconnect logic timer driven, e.g. allow only delayed reconnects and set a top limit for number of reconnects per hour. Best is to work out a reconnect policy, something like reconnect only if the server was at least identified once in current session, etc. This will prevent harming the network with reconnects going berzerk.
