Hi experts,

I was wondering how I can use a net send in my program. Not a net send through DOS (shellexecute) but one actually using the net DLL. Thanks.

it seem you dont want to show your app user the dos screen thats simple and also i dont know any free compnent or comercial compnent to do this trik

check this code put it under a button e.g
procedure TForm1.Button1Click(Sender: TObject);

shellexecute(handle,'open',pchar('net'),pchar(' '+'send' +' '+ edit1.text + ' ' + edit2.text),nil,SW_HIDE)


and edit1 will be the host name or the ip number of the computer
edit2 will be the message

once u hit the button the message will apear instantly in his computer
and no one will see the command line screen
also this is better than a component this way save's space

Try This:

function NetSend(dest, source, msg: string): longint;
 TNetMessageBufferSendFunction = function(servername, msgname, fromname: PWideChar; buf:
 PWideChar; buflen: Cardinal): longint; stdcall;
 NetMessageBufferSend: TNetMessageBufferSendFunction;

 SourceWideChar  : PWideChar;
 DestWideChar   : PWideChar;
 MessagetextWideChar: PWideChar;

 Handle      : THandle;

 Handle := LoadLibrary('NETAPI32.DLL');
 if Handle = 0 then
 Result := GetLastError;
 @NetMessageBufferSend := GetProcAddress(Handle, 'NetMessageBufferSend');
 if @NetMessageBufferSend = nil then
 Result := GetLastError;
 MessagetextWideChar := nil;
 GetMem(MessagetextWideChar, Length(msg) * SizeOf(WideChar) + 1);
 GetMem(DestWideChar, 20 * SizeOf(WideChar) + 1);
 StringToWideChar(msg, MessagetextWideChar, Length(msg) * SizeOf(WideChar) + 1);
 StringToWideChar(Dest, DestWideChar, 20 * SizeOf(WideChar) + 1);
 if source = '' then
  result := NetMessageBufferSend(nil, DestWideChar, nil, MessagetextWideChar, Length(msg) * SizeOf(WideChar) + 1)
 end else
  GetMem(SourceWideChar, 20 * SizeOf(WideChar) + 1);
  StringToWideChar(source, SourceWideChar, 20 * SizeOf(WideChar) + 1);
  result := NetMessageBufferSend(nil, DestWideChar, SourceWideChar, MessagetextWideChar,
       Length(msg) * SizeOf(WideChar) + 1);

cqhall - (S)/He uses the API contained on NETAPI.dll on what
the NET SEND is based. It calls the DLL, gets the function
and configure the parameters to finally execute the send.
After it, it unloads the DLL and free all memory.

amjedmsa - S/He uses the shell ShellExecute function available
on shellapi.pas unit on Delphi. It runs the NET.exe executable
like you would make it manually.
