The warning does not apply in my case, I was dealing with an executable (tray icon app) that receives the data.
I'll remember the warning for DLLs

Thanks

did you notice the spams here?

Anything you can do about it before its overwhelms us?

BTW If you notice a spammer from the Netherlands, I'm willing to go visit him with a baseball club.

Does the exe/dll that receives/handles communication have to create the IPC channnel, or could the sending app do that as well?

I will now be investigating Layered Service Providers, that goed one level deeper, I believe.

I currently do 'the usual' hooking process (see code outline below). Doing it this way means that the incoming/outgoing data is processsed immediately, per packet. I now have the situation where I need more than one consecutive block of incoming data to base decisions on (how to modify the data). [I...

Hi, my Delphi 2007 refuses to compile because of this error. My code: with List do begin for i := 0 to Items.Count-1 do begin if CompareText(Items .Caption, SomeStr) = 0 then so there's not much I can do there. The help says: Based on the current overload list for the specified function, and the pro...

I already tried 0 - it seems to do 'unlimited'.

You mighty want to update your docs, because it specifies a default parameter of 16.

And thanks for all the feedback!
Jan

Please let em ask my question more precisely:
In those cases <> 1: Unlimited or 16?

Bye

According to the online help: // if the order of the messages is crucial for you, set "maxThreadCount" to "1" // in its current implementation "maxThreadCount" only supports "1" or unlimited // the parameter "maxQueueLen" is not yet implemented at al...

Hi all

I used the ASMSamplingProfiler
http://code.google.com/p/asmprofiler/
to try and find out what is making my service slow.
I notice 99% samples falling in madCodeHook/PipedIPCThread1
(madCodeHook/handlePipedIPCMessage takes only 0.5%)

What does this mean?

Thanks
Jan

The name of the executable that your DLL is hooked into can still be retrieved with ParamStr(0) The location where your DLL was loaded from can be retrievd with function GetModulePath: string; // Returns the path where the DLL is loaded from var Buf : PChar; i : Integer; begin Result := ''; GetMem(B...

Hi Matthias

(1) But is the FALSE result of UninjectLibrary reliable?
(2) Any ideas how I could find out what is going on if it fails?

Thanks
Jan

I found out that different IPC handlers can run concurrently, as long as I make sure they 'have' their 'own' data. This does not answer if they are threaded though ;-) Also I have not seen 'nested calls' i.e. an IPC handler getting called while it is processing (and one of them is called *frequently...

Hi all

1)
Is there a way to detect that the timeout happened?

2)
I assume that the 'responding' process (which is handling the IPC message) has no idea that the sender gave up after the timeout. What happens if the responder stuffs data into the AnswerBuf after the timeout.

TIA
Jan

This code returns an error message with GetLastError 0 That is not much info :? Is there a way to get more info on what failed? procedure UnInjectCoreDll; var Res: Boolean; begin Res := UninjectLibrary((ALL_SESSIONS{ or SYSTEM_PROCESSES}) and (not CURRENT_PROCESS), 'CORE.DLL'); if not Res then LogEr...
