Re: Detecting that an executable is already running (so duplicates don't run) Nick_Kisialiou23-Apr-06 14:03 Nick_Kisialiou 23-Apr-06 14:03  I think any named kernel object will do, it does not have to be a mutex. Re: Detecting that an executable is already running (so duplicates don't run) Stephen Hewitt23-Apr-06 14:22 Stephen Hewitt 23-Apr-06 14:22  Yes, there is no need to use a mutex if you prefer some other option. As I said, there are many ways this can be done. Steve Re: Detecting that an executable is already running (so duplicates don't run) David Crow24-Apr-06 3:07 David Crow 24-Apr-06 3:07  See here.

John R. Shaw22-Apr-06 23:16 John R. Shaw 22-Apr-06 23:16  I do not know the answer, but please do no post every error message. Once they start to repeat them selves it becomes redundant and you are wasting sever storage space. You need to figure out why the first error says the type is a redefinition and go from there. If you solve that problem the rest of them will probably go away.

Trollslayer23-Apr-06 0:07 Trollslayer 23-Apr-06 0:07  Redefinition usually means you have included a header file more than once. Elaine The tigress is here Re: Can anyone tell me why am i getting these errors? Rilhas23-Apr-06 1:45 Rilhas 23-Apr-06 1:45  There is an important nuance to note: I think Elaine's answer is correct for the first errors, where redefinition is the problem, but some other errors point out that the multiple definitions have different linkage. This would mean that the multiple inclusions could have some of the conditions change. For example, if this was in a header file: #ifdef USE_C extern C { #endif typedef struct { int x; int y; int z; } Vector; #ifdef USE_C } #endif Then if one inclusion defines USE_C and the other doesn't then you may get the diferent linkage error, because one will declare the structure as C and the other as C++.

How can i do so ? Imtiaz Re: Property Sheet and Property Pages Michael Dunn22-Apr-06 22:58 Michael Dunn 22-Apr-06 22:58  Handle PSN_KILLACTIVE and do your validation there.

Suprise, suprise. And this program has to wait for a client to connect and then do something with the client. I put the wait for client, etc. stuff into a thread so that my interface is still useable, but since it's a thread my main program continues running. How can I prevent this ? So the Interface of my Main Program should keep useable but it should not continue work till a client connected. Any Ideas or Suggestions ?

I assume you mean you don't want the user to be able to use the UI? If this is the case just disable the main window or bring up a modal "please wait" dialog that is dismissed when the worker thread is done by sending a WM_CLOSE message to it.

All in all just want the UI to be drawn correctly. And the possibility to stop the work (so interaction). Hope this helps, Benedikt Re: Wait for Thread Nick_Kisialiou22-Apr-06 21:59 Nick_Kisialiou 22-Apr-06 21:59  Can you use ::WaitForSingleObjectEx(...) function? Re: Wait for Thread Stephen Hewitt22-Apr-06 22:21 Stephen Hewitt 22-Apr-06 22:21  If he uses this API the UI will not redraw properly while the worker is running. Steve Re: Wait for Thread John R. Shaw22-Apr-06 22:24 John R. Shaw 22-Apr-06 22:24  That is easy just do not return from the thread util a client has reacted. No wait a client may never react and then you end up with an infinite loop. There are multiple ways to provide a solution to this problem, the simpilest is to disable all commands that require the client to communicate with you. That is anything that is not be dependent on an outside source, like close application. The main thread should never be disabled, because you always need the option of shuting down the program.

I now want to create a single DLL with functions which will be forwarded to the several existing DLL's. Very much on the same line as the Windows Kernel.DLL is implemented. Do I have to write code to generate such thing, or, are there settings in the VCPP IDE to achieve this the Microsoft way. I am thinking of something like: _MyFunction=Existing.Dll:?MyFunction@YKKKK@Z LateNightsInNewry Re: Forwarding Functions between DLL's cmk22-Apr-06 14:57 cmk 22-Apr-06 14:57  You've kinda answered your own question: "I now want to create a single DLL" "Do I have to write code to generate such thing" You have to write the dll. However, it sounds like you could write a tool to generate the code from a config file with the mappings the way you want (_MyFunction=Existing.Dll:?MyFunction@YKKKK@Z). ...cmk Save the whales - collect the whole set
