SO als erstes noch kurz, benutz ich den Befehl richtig ?
  Delphi-Quelltext
1:
2:
3:
4:
5:
6:
7:
8:
| var
zahl:Cardinal;
wahr:boolean;
begin
zahl2:=True;
iphlpapi.GetTcpTable(nil,zahl,wahr);
Label1.Caption:=IntToStr(zahl);
end; |
Was kann man damit machen?
Kann der Befehl in einen Array und es können dann versch. Sachen ausgelesen werden ? _________________ Wer andere beherrscht ist stark,

Wenn ich mir die Deklaration und den dazu gehörigen Eintrag im MSDN anschaue:
C#-Quelltext
1:

5:
| DWORD GetTcpTable(
PMIB_TCPTABLE pTcpTable,
PDWORD pdwSize,
BOOL bOrder
); |
Nein 
Um's vollständig zu machen:
| MSDN Library \ Plattform SDK August 2004: | GetTcpTable
The GetTcpTable function retrieves the TCP connection table.
C#-Quelltext
1:
2:
3:
4:
5:
| DWORD GetTcpTable(
PMIB_TCPTABLE pTcpTable,
PDWORD pdwSize,
BOOL bOrder
); |
Parameters
pTcpTable
[out] Pointer to a buffer that receives the TCP connection table as a MIB_TCPTABLE structure.
pdwSize
[in, out] On input, specifies the size of the buffer pointed to by the pTcpTable parameter.
On output, if the buffer is not large enough to hold the returned connection table, the function sets this parameter equal to the required buffer size.
bOrder
[in] Specifies whether the connection table should be sorted. If this parameter is TRUE, the table is sorted in the order of:
1 = Local IP address
2 = Local port
3 = Remote IP address
4 = Remote port
Return Values
If the function succeeds, the return value is NO_ERROR.
If the function fails, the return value is one of the following error codes.
Return code --> Description
ERROR_INSUFFICIENT_BUFFER --> The buffer pointed to by the pTcpTable parameter is not large enough. The required size is returned in the DWORD variable pointed to by the pdwSize parameter.
ERROR_INVALID_PARAMETER --> The pdwSize parameter is NULL, or GetTcpTable is unable to write to the memory pointed to by the pdwSize parameter.
ERROR_NOT_SUPPORTED --> This function is not supported on the operating system in use on the local system.
Other --> Use FormatMessage to obtain the message string for the returned error.
Example Code
The following example retrieves the TCP connection table and prints the state of each connection.
