Hello,

From where can I get the parameters which are required for
CHttpConnection class.
I basiacally want to get data from a remote computer .I have the IP address of the computer .Both the computers have internet access.
I have been through all the MFC iternet classes.But I do't understand from where these parameters be available.

CHttpConnection* GetHttpConnection( LPCTSTR pstrServer, INTERNET_PORT nPort = INTERNET_INVALID_PORT_NUMBER, LPCTSTR pstrUserName = NULL, LPCTSTR pstrPassword = NULL );

Is this related to your ip address question below?

To get a file from a remote computer, the remote computer needs some kind of server to serve
you the file.

To use CHttpConnection there needs to be an HTTP server running on the remote computer.
To use CFtpConnection there needs to be an FTP server running on the remote computer.
etc.

Hello
Yes my problem is related to the ip address problem.
My remote computer is having an internet connection.
It does not have any server.

I thought ip address should be enough to recognize the PC on the Net.

If I am using a CDatabase class to access a remote computer's database then what kind of connection string should I provide.

Can you give me a link for the same.
I think there are many people on this site asking the same question.You can link me to that question if possible.

Without some kind of "server" running on the remote machine (HTTP,FTP,SQL Server, etc.) then
an IP address isn't useful. There needs to be some application waiting for connections at the
given address (IP/Port).

Connection strings vary between databases - what database are you connecting to?

Hello,

Right now I am connecting to access database but soon I will have to connect to SQl server.

I have created an ODBC driver for my PC for access database but if I have the database on a remote computer then I will have add something in the network connections option of ODBC driver and provide a proper connection string in my CDatabase class isn't it?

But I don't know how to do the changes?

I recommend using the SQL Native Client to connect.

Also download the SQL Server Books Online (BOL).

In that documentation is the following article - Using Connection String Keywords with SQL Native Client[^]

Maybe the following excerpt from MSDN will be helpful:

Remarks
It is only necessary to call DestroyIcon for icons and cursors created
with the CreateIconIndirect function.
Do not use this function to destroy a shared icon.
A shared icon is valid as long as the module from which it was loaded remains in memory.
The following functions obtain a shared icon: 

LoadIcon 
LoadImage (if you use the LR_SHARED flag) 
CopyImage (if you use the LR_COPYRETURNORG flag and the hImage parameter is a shared icon)

If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

U have to download Micrsoft Platform SDK that is applicable for windows 2000 Family i me from 2000 onwards if i am correct. Download the sdk. Then you can
develop the programs by Using the Interfaces otherwise its difficult (Not possible) so do it first.

Hello,

If I want to get a flat file or a database table from a remote computer then only the information about the remote computer's IP address is enough for me.Or there is something else I will have to ask for from the remote PC.

How will a password fit into accessing data?

I have gone through many MFC classes about internet programming but which class will help getting a flat file or database table from a remote computer.

Thanks

Hello,

Ya ,I have been through a couple of Classes available with VC++ but the the parameters required for the handshake is what I have not understood.

My remote computer is not a server but has an internet connection.I know its IP address

Can I make some changes in my ODBC connection string and access the database or should write a program to use the remote table.

Use ShellExecute function in your menu handler.
e.g

ShellExecute(NULL,_T("open"),_T("calc.exe"),NULL,NULL,SW_SHOW);

Since the tree view is a window, you can set its size calling SetWindowPos, see MSDN for details. Of course you have first to resize the tree view's parent window.

Hope that helps
