I'm thinking this is just a random fluke in my code, but I don't know.

Sometimes, when I try to login with 0ms ping I end up with 16ms instead.  This strikes me as odd since I have dial-up.

Public Sub p0x50()
   Form1.sckBNET.SendData Chr(1)
   InsertDWORD 0
   InsertNonNTString "68XI" & varProduct
   InsertDWORD "&H" & GetVerByte()
   InsertDWORD &H0
   InsertDWORD &H0
   InsertDWORD &H0
   InsertDWORD &H0
   InsertDWORD &H0
   InsertNTString "USA"
   InsertNTString "United States"
   sendPacket &H50
   If frmLogin.chk0Ping.Value = vbChecked Then
       InsertDWORD &H0
       sendPacket &H25
   End If
End Sub


This is recieving 0x25
Case &H25
       If frmLogin.chk1Ping.Value = vbChecked Then
       ElseIf frmLogin.chk0Ping.Value = vbChecked Then
       Else
           InsertNonNTString Mid(data, 5, 4)
           sendPacket &H25
       End If

Any ideas why this happens?

Try packet logging it.  If you're sending 0x50 and 0x25 in two seperate clumps, I'm sure it's just your connection being a little slow.

Yeah that happened to me a couple times.

Should disable the Nagel Algorithim when connecting and ew at using an object to determine whether or not to spoof the ping.

This happens to me when using a slow proxy or a slow dial-up connection.

You are sending 0x25 to Battle.net before Battle.net sends it to you to get 0 ms ping time. However, since your connection is so slow, Battle.net actually doesn't get your 0x25 until right after it has sent 0x25 to you.

That is why you are getting 16 ms ping time.

Agreed - ping should never be clumped.

Quoteew at using an object to determine whether or not to spoof the ping.

What's wrong with giving the user a checkbox to ask if they want the ping spoofed?


Also, ping time has nothing to do with what type of connection your on.  You can have a dialup connection and a slow ping, as long as nothing else is plugging up the stream.  Ping is based on the time it takes for a tiny bit of data to be transferred, and has more to do with distance.

Actually, in order to get the 0ms ping,  you may want to have the Nagel enabled...You need the 0x25 packet to be clumped with 0x50.
If they are sent separately, the chances Battle.net will send 0x25 before it recieves your 0x25 will be greater.

If you handle the clumped packets correctly I don't see why they are a problem.

Programming 101: Don't use objects in functions because the object names may need to be changed or removed sometime in the future and in which case you'd have to hunt down the functions that contain the object and change them. Checking objects also takes a much longer time to check than a variable.

That's incorrect. Battle.net won't send 0x25 until it receives your initial logon packet (SID_AUTH_INFO or similar). By disabling Nagle, you ensure that your ping packet is sent immediately, and can then wait an appropriate amount of time before proceeding with your logon as normal.

Where do you suggest reading the checkbox?  Passing it as a parameter would be dirty, and saving it in a global variable temporarely would even worse (having a copy of it that you might forget to update, etc.).  

Lord: VB comes before Programming 101

It doesn't always happen, that is why there is no packet log.

But won't clumping your 0x25 with your SID_AUTH_INFO ensure it recieves 0x25 immediately after SID_AUTH_INFO...

What would happen if you sent 0x25 before 0x50?
