the ending cast you make in the message box is not necessary...

You may want to reflect on that statement a bit.
[EDIT]
toxcct : the ending cast you make in the message box is not necessary...
I don't know why this was voted 1.
I was trying to (politely) point out that this is incorrect.
You do need the cast.

Hi,
I'm using a CDialogBar in my App, but i have a problem using it (CDialogBar) :
when i add a button to my DialogBar Resoure.
When i run my app, buttons on my CDialogBar always apear disabled (I'm sure that i have not change the state Visible or Disable).
when i debug to see if they are disabled or not , i found that they are not disabled
BOOL b = GetDlgItem(IDC_MY_BUTTON)->IsWindowEnabled();
result (b = TRUE) but visualy button is Disabled !!!!!!!!!!!!
this happen just with buttons.
INew.
thanks a lot.

I think "enabled" means it's visible, not that it is interactable with the user. When I want to hide controls, I use their EnableWindow() method to make them invisible.

Hi every one,
I'm a new commer. I'm doing a project about the fingerprint system. I have a sensor ( MBF200 ) to capture the fingerprint image and send it to my PC via COMPort. The data which is sent from sensor is a matrix of 256 rows and 300 columns, in which each elements is one byte ( gray scale value ) with a range from 0 to 255. This sensor only can take a gray image ( not a color Image ).
Now, I want to write a program for receiving that data, save that image in BMP format ( *.bmp ) and show it on the PC screen. I'm using Visual C++ lanuage and the MSCOmm control for accessing to Comport. My operating system is microsoft Windows 98 ( Second edition ). How can I do that ? Please help me !
Thank you.

Use the sensor's SDK in the VC++ app to get and display the image.

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.

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!
