<DIV style="FONT-SIZE: 12pt; FONT-FAMILY: arial, helvetica, sans-serif">GV, I want to make some minor changes in the Packet code. That is why I want to recompile it. This is an open source project and folks just should be able to try things out right? I have timing/synchronization issues on a high performance system and I am curious about what is going on at this low level. I have put in some callbacks in packet that are made during the spinning to wait between packets sent to let me know what is going on. Basically I am using a Quad core system that has different processes running on different cores. I am trying to see what each core is up to at any one time. These low lever routines are being used by several upper level applications. If one thread (above) is being stalled then I am wondering if another stack of packets could be sent. This is not the whole story but it is what I am exploring. It should be ok to experiment with this project,
right?</DIV>

<DIV style="FONT-SIZE: 12pt; FONT-FAMILY: arial, helvetica, sans-serif"><FONT face="Courier New" size=2>Definitely. I was just asking because compiling WinPcap (actually installing it) is a major pain in the neck, and I thought you were just trying to build a WinPcap based application. To simplify your job, when you are experimenting you can safely keep packet.dll and wpcap.dll in the same folder where you have your application (that's what I do during development).</FONT></DIV>

The ones the installer put there will load and run but exactly named equivalents built on the same system cannot be seen/loaded. Totally strange.

<DIV style="FONT-SIZE: 12pt; FONT-FAMILY: arial, helvetica, sans-serif">
<DIV>Well, if I install the Wdpcap exe, and it installs a Packet.dll in the Windoes\System - or SysWOW64 directory, it can be found and runs. But when I build my own Packet dll in Win32 or 64 bit and put both in Windows System or SysWOW64, the Vista cannot "see" or load them. Whne I rename mine to Packet.dll_mine and rename the one installed by the Wdpcap installer to Packet.dll, everything is fine. By the way, under XP Pro, my Packet dll loads and runs fine. </DIV>
<DIV> </DIV>
<DIV>Something is preventing a debug version to load under Vista. Anyone else having this problem and have a solution?</DIV>
