//Free resources and disconnect

SQLFreeHandle frees resources associated with a specific environment, connection, statement, or descriptor handle.

SQLFreeStmt stops processing associated with a specific hstmt, closes any open cursors associated with the hstmt, discards pending results and, optionally, frees all resources associated with a statement handle.

throw new InvalidOperationException(Resources.FTPClient_NoFTPSiteSpecified);

throw new InvalidOperationException(Resources.FTPClient_HDSourceFileDoesNotExist);

To close the handle returned from InternetConnect, the application should call InternetCloseHandle. This function disconnects the client from the server and frees all resources associated with the connection.

The hbmColor and hbmMask are pointers to unmanaged data and must be deleted after use. The following code will grab the icon info for a cursor handle and dispose of the unmanaged resources, if needed:

' For loading icon-resource identified as integer ID

C++/CLI: This solution allows you to load an image from an unmanaged resource in the assembly. In my case I added a .cur file to my .rc. The cursor had an ID of 101. After loading the cursor I assigned it to the Forms::Cursor.

To use integer resource ID instead of string, and avoid using MAKEINTRESOURCE, prepend the integer with '#'. For example, to use resource ID 32512, enter "#32512" for lpszName.

Summary

The WNetGetUniversalName function takes a drive-based path for a network resource and returns an information structure that contains a more universal form of the name. What this means is that you can take a file name from a network drive can be converted to a UNC version that may be used from other computers on the network that do not have the same drive mappings.

WM_FONTCHANGE

0x1D

An application sends the WM_FONTCHANGE message to all top-level windows in the system after changing the pool of font resources.

Summary

Releases resources associated with a buffer allocated previously as the result of a function call by a fax client application.

Summary

The RasHangUp function terminates a remote access connection. The connection is specified with a RAS connection handle. The function releases all RASAPI32.DLL resources associated with the handle

Summary

Cleans up the Windows Sockets resources. Ensure this method is called after every successful call to WSAStartup().

if (!LookupAccountName(this.ResourceName, this.UserName, Sid, ref cbSid, referencedDomainName, ref cchReferencedDomainName, out sidUse))

aSystemName.SetTo(this.ResourceName);

If MsgBox("Are you sure you want to disconnect this resource?", MsgBoxStyle.YesNo) = MsgBoxResult.Yes Then

/// Unable to contact resource. Connection timed out.

The NetShareGetInfo function retrieves information about a particular shared resource on a server.

const int NERR_NetNameNotFound = 2310; // This shared resource does not exist.

You can also use the WNetAddConnection2 and WNetAddConnection3 functions to redirect a local device to a network resource. Connections added by NetUseAdd are not shown in the Explorer. You should use one of the WNetAddConnection methods to make the networkdrive visible in the explorer.

Summary

The NetUseDel function ends a connection to a shared resource.

Summary

NetUseEnum - The NetUseEnum function lists all current connections between the local computer and resources on remote servers.

Summary

The MultinetGetConnectionPerformance function returns information about the expected performance of a connection used to access a network resource.

Summary

The WNetAddConnection2 function makes a connection to a network resource. The function can redirect a local device to the network resource.

The WNetAddConnection2 function supersedes the WNetAddConnection function. If you can pass a handle to a window that the provider of network resources can use as an owner window for dialog boxes, call the WNetAddConnection3 function instead.

Summary

The SCardConnect function establishes a connection (using a specific resource manager context) between the calling application and a smart card contained by a specific reader. If no card exists in the specified reader, an error is returned.

Summary

The SCardEstablishContext function establishes the resource manager context (the scope) within which database operations are performed.

Summary

The SCardFreeMemory function releases memory that has been returned from the resource manager using the SCARD_AUTOALLOCATE length designator.
