Normally I know how to set breakpoints and use breakpoints.I got a VC++ sample code from disk.When I set breakpoints and debug it,it show the following messages:One or more breakpoints cannot be set and have been disabled and the application will stop at the beginning of the program.Please tell me how to solve this problem .
Thank you very much for your answer!

Looks like you are running in Release mode. Change the build configuration to Debug mode.

How can i ban a Host or IP address before i do my accept() call ?
Can i pool the connection queue ?
Now im doing this:
accept->check for valid IP->If it's valid(do nothing)else->close the socket.
i belive this can be a bit insecure i dont really know.
I what to call my checking routine before doing the accept() any ideas ?

It would probably be better to do this at the firewall level.

U can go for SSL Socket
Bu buddy you have to make he call for Accept() function before checking is this connection coming from valid ip

Which class are you using? If you’re using CAsyncSocket then have you looked into over riding OnConnect? I dont have any code handy but there is a chapter in Secure Coding about doing this.

[LPCONDITIONPROC lpfnCondition]
Procedure instance address of the optional, application-specified condition function that will make an accept/reject decision based on the caller information passed in as parameters, and optionally create or join a socket group by assigning an appropriate value to the result parameter g of this function.
defines a callback its a verry intresting option but not code samples are supplied by MS any ideas ?

Hi evey1,
I am working on a dll addon for an app1 where i need to retrieve some info from app2. but the app2 sdk allows only to collect data via WM_COPYDATA (it will send you to your window). Now, if I were to make a separate application for this, I would just collect the data from my WindowProc. But here I have to do this from a dll. Also I understand there is no HWND for a dll.
One work around this problem i am thinking of is to create a hidden window from the dll and use its windowproc to handle WM_COPYDATA. But is there any other easier way to do this? I am not using MFC but might consider using MFC if this can be done easily. Thanks in advance ppl.

Your idea of creating a hidden window from the DLL is the right way to do this.

I know it's not VC++ but I'm trying to capture video with my camera and i'm using the vfw.h header file. After I got done adding the functions that were not in the header (Using MSDN Library) i tried to compile the program but i get a link error with undefined references to the functions i added. I looked all over the internet to find out why i would get the link error, but it still won't work even after doing what some pages said. Can anyone help me with this problem?
Thanks in advance,
me...;P

If you have the source, you should add those cpp files to the project, else you'd have to add a lib (or multiple libs as the case might be) to your linker's additional library list.

Hey,
Thank you for you answer, unfortunately it is still not working. I'm going to try one more thing and hopefully it will work.

not really a vc++ question, but I want to know what is the fastest way to convert the unix-style line ends (cr/lf) with the dos style (cr) for a bunch of files?
thanks!

"Unix line ending" is only LF, "Windows line ending" is CR + LF and "Mac OS line ending" is CR.

you are right, thanks for the correction. Any suggestions for a batch conversion?
thanks!

Do you want to program it yourself or do the one-time job? If first, you will have to copy files line by lines, I don't see any special tricks to do it faster. If you just need the job done, get one of converter from internet and make a batch file using "for" command.

I did this conversion years ago, but since I did not have too many files, I just read from the source file and wrote to destination file, character by character, replacing LF (??) with CR LF (??).
The reason for character-by-character rather than line-by-line is that I also converted DOS-style line-drawing characters to 7-bit ASCII ("-", "|", "+", etc.) which Windows was happy with.
I seem to remember that some OS-2 files used LF CR instead of CR LF, which confused Windows (or maybe WinWord 6), so I fixed those as well.
My app was a 16-bit DOS app, using VC1.52!

I need to create a control dynamicly and then get its DC to draw text and so on,just do as the following code:
BOOL bCreate = m_hEdit.Create(WS_CHILD | WS_TABSTOP | WS_VISIBLE |ES_LEFT , rectEdit,this, IDC_COMBOTREE_EDIT);
if (bCreate)
{
CWnd* pParent = GetParent ();
CFont* pFont = pParent->GetFont ();
m_hEdit.SetFont (pFont);
}
CDC *dc=m_hEdit.GetDC();
dc->DrawTextW(_T("ok"),-1,CRect(0,0,30,20),DT_LEFT);
dc->SetBkColor(RGB(0,0,0));
m_hEdit.ReleaseDC(dc);
but it doesn't work,I can never see the "ok" in the edit.
Any help is appricited.
Thanks!

Can you use SetWindowText since its an edit window?

SetWindowText() *can* draw the text in the edit-ctrl.
In fact, its the only way to do it this side from owner-drawing the whole control.
Your way paints the text at the exact place where the Edit-ctrl is located, triggering the edit-ctrls redraw.
Your text gets overwritten.
If what you want to acomplish is putting your Text into the Edit-ctrl, then SetWindowText() is the way to tell the Edit-ctrl what text it has to draw.
If you want something different, you should subclass CEdit and do it yourself, possibly delegating routine tasks to your baseclass CEdit.
