Hi,
You can use custom build step for copying the DLL to destination folder.
Go to "Project | Properties | Custom Build Step | Command Line".
Enter Copy command.
Hope this will help you.
Regards,
Paresh.

Hello everyone, i finished with yesterdays work and got a fully functional crytography class that builds perfectly and today im starting to write my dialog based aplication.
i created a few dialogs and im trying to link them but i havent found how.
i know its an easy question but still i would like a recomendation.
in dialog A theres a button, when i press it i want to make dialog B appear on the screen, i've tryed the ->Create(); command but i think im using it wrong
ps: the aplication is in C++ for visual studio 2005

So dialogA is showing when you run the application? If so then you have code that does shows a dialog, it's the same for DialogB, yes?
Abandon hope all ye who answer here.

yes, dialog A runs when the App starts the code is the following:
CZEUSv2008Dlg(CWnd* pParent = NULL); <br />
CEncriptacion * dialogo_encriptar;
but i dont know how to use it since im copying from a thing done like 10 years ago.
i tried
dialogo_encriptar->DestroyWindow();<br />
dialogo_encriptar->Create();
but it gives me
error c2027 for using an undefined class
and a c2227 for the left part of the "->" must point to a class struct union or generic type
im just plain confused with this

Where you tried it? I mean, does the posted code belong to a single source file?
Which line is the error c2027 for?
Maybe you need to post more code.

i asked my dad about it and he said it was from an old stupid class called "MyDlg" so he told me to find a new way to call dialogs.
now that code and way of doing it its obsolet so if i acomplish solving this issue i solved the issue for all the dialogs that need to be called.
already tryed to use the .DoModal(); thing but it didnt work

That all depends on if you want a modal or modeless dialog. If the former, use DoModal(), much like you are already doing in your app's InitInstance() method to bring up dialog A.

It wasn't his verbiage that bothered me (I'm from Oklahoma so I get accused of talking funny all the time). It was that he talked about modal while linking to a modeless article.

That reminds me of an incident in the elevator yesterday. The elevators in the lobby of our building can go up (to floors 2-15), or down (to floors B and SB). Above the elevator doors are red arrows pointing down. They are lit when the elevator is going down (and unlit otherwise) to let those getting on know where they are headed to. I got on yesterday with a guy that was apparently new to the building. We were both going up. Because I had gotten on so quickly, he asked me how I knew that the elevator was indeed going up. I told him it was because the red arrows did not tell me it was going down. Sort of a reverse logic thing.

They are already somewhat unreliable (built in the 50s). Worst case, and has happened, I go to the 7th floor via the sub-basement.

Can be used SetupComm() after port initialization and reading of some data to change buffer sizes?

No, after you have read data...you will need to close the handle, reopen it and call SetupComm() before reading/writing.

Hello,
can I somehow find out how many thread are waiting
for an event on WaitForSingleObject (or how many Threads
have been released when setting it?
Alex

WaitForSingleObject waits for only one object. And to know the state of a thread, use getExitCodeThread.
OK,. what country just started work for the day ? The ASP.NET forum is flooded with retarded questions. -Christian Graus

Thank you for your answer.

But multiple threads can wait for one object - and I would like to know how many. The problem is:
when I use a (synchronized) counter before the WaitForSingleObject,
how do I know if the Thread has already reached it and is waiting
or was interrupted before - I can not unlock the counter atomically
with the WaitForSingleObject call...

There's no way reliably. What thread would be examining this thread to see where it's at?
What are you trying to do and how is this counter involved? There may be a simpler solution

I wanted to implement a multiple reader/single writer lock.
The counter counts the number of waiting readers (which
then wait until the event is set).
If a writer unlocks, it sets (or pulses if there are writers
waiting) the event so that all waiting readers can resume -
but only if they already wait.

The lack of an atomic lock/counter-adjust API makes it tricky.
There's a ton of solutions on the web (e.g. search "reader writer lock") that vary in performance and whether
they favor the reader thread(s) or the writer thread(s).
Even if you're looking to design your own, they're worth looking at IMO.
Here's an interesting article: Implementing a Reader-Writer lock[^]
along with its companion article: Analysis of Reader-Writer lock[^]
Here's a simple example - straight forward, if performance isn't a major concern: Reader/Writer Lock[^]
Hope that helps a bit,
Mark
