Re: help with self-checking executable (CRC) Neville Franks31-Mar-02 10:25 Neville Franks 31-Mar-02 10:25  I would suggest doing it another a seperate thread if the .exe is large. If you are doing it to check if your program has been hacked then using a separate thread also makes it more difficult to hack. Don't do it the second the app starts, but after a while. I'd also look at using something stronger than a CRC, such as MD5.

The problem is that I want to fire event when mail issent and I want to fire event when all mails are sent. The problem is that one of my worker threads has to fire event by asking main thread to fire event. But this doesnt work that way it gives error in kernel32. What seems to be the problem and how can i solve it. I can only fire event when I dont have any thread working. In my dream, I was dorwning my §orrow§ But my §orrow§, they learned to §wim Re: Firing Events in multithreaded OCX Tim Smith30-Mar-02 4:27 Tim Smith 30-Mar-02 4:27  Did you marshal the interface to the worker thread? Tim Smith I know what you're thinking punk, you're thinking did he spell check this document? Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk? Re: Firing Events in multithreaded OCX Tili30-Mar-02 7:35 Tili 30-Mar-02 7:35  Well here is the deal. I pass pointer to worker thread of Control Class so they can communicate. Everything works fine untill I call the COntrols public Function to call Private Event firing function and there I get Access violation and VS shows me assembler code. I am using MFC not ATL. I just want my each thread to be able to fire event telling the container that it just sent an email. SO in your opinion what should I do to make things go right. Thanks in advance In my dream, I was dorwning my §orrow§ But my §orrow§, they learned to §wim Re: Firing Events in multithreaded OCX Todd Smith30-Mar-02 5:12 Todd Smith 30-Mar-02 5:12  What are you using to fire an event? There are several ways to communicate between worker threads and your main thread. Todd Smith CPUA 0x007 ... shaken not stirred Re: Firing Events in multithreaded OCX Tili30-Mar-02 7:44 Tili 30-Mar-02 7:44  I am simply giving each thread a pointer to my Control class. The point is it works fine every way except when I call Control's Public function to call its private function to fire event. The problem is there. ACCESS VIOLATION. I am using MFC. What do you suggest me to do. THis is the code in ThreadProc pCtl->MailSent(); // and this is thee function MAilSent in Control class void CSMTPControl::MailSent() { FireMailSent(); // This is where it gives access violation } ////////////////////// as it is an OCX so I cant use Timer in it otherwise I'll set a volatile global variable and will set timer in main thread to firevent when volatile vairblae asks. But I want something else to do to solve it. cuz it is an OCX i cant just send messages to it beacause it is invisible at run time.

I'm having touble as well, but from ATL. Call a COM method, start a worker thread, and return. Worker thread fires a connection point event. Thanks, Giles Re: Firing Events in multithreaded OCX Giles30-Mar-02 8:48 Giles 30-Mar-02 8:48  While I don't have an answer, let me know how you get on, as i had the same problem when looking at something similar last week. Mine was with ATL though. I had implemented a connection point in an object, and wanted to be able to start a worker thread from the COM method, so it could return asyncronously. The worker thread would then fire the event before terminating.

But do you mean i should use CoMarshalInterface. But this is a headache isnt there any simple way.Thanx for your help anyway.

TIA. #define MOSTLY_LEAN_AND_MEAN Re: creating a long filename Nish Nishant30-Mar-02 0:43 Nish Nishant 30-Mar-02 0:43  What's stopping you??? You can use any file creation mechanism MFC/SDK/.NET to do this. Nish Has anyone seen my sig? Re: creating a long filename Amit Dey30-Mar-02 6:20 Amit Dey 30-Mar-02 6:20  very silly!!(I know) the thing was that I used CFile and CStdioFile at first and Open(mylongfilename) was not working. Have had better luck with CreateFile using UNC format, the way it's supposed to be....right?. #define MOSTLY_LEAN_AND_MEAN Re: creating a long filename Nish Nishant30-Mar-02 6:44 Nish Nishant 30-Mar-02 6:44  Amit Dey wrote: very silly!!(I know) the thing was that I used CFile and CStdioFile at first and Open(mylongfilename) was not working.
