Hi
I am trying to add a dialog to an existing project.

I add the resource file .rc then add the dialog and double click on it an the class creator/wizard thing appears so I enter the class name.

Now I try to add a button and test it by adding a show message to it's event handler.

The problem is, it doesn't compile and the error is:
IDD_DIALOG1 = undefined

enum {IDD = IDD_DIALOG1};

Help!

why did you copy the .RC file ???

as far as i know, when you create a dialog, you set its ID. the same when you add a button to the dialog... then, you can associate an event handler to that ID...

I created the .rc file i.e. added it to the project
then the dialog is added as a child of the .rc file

Am I doing this all wrong?

Can you step me through what you would do to add a dialog with a button?

Cheers

Just above class Decalaration add #include"resource.h" and then rebuild your project

#include"resource.h" didn't work
still get the same error
error C2065: 'IDD_SHUTDOWN' : undeclared identifier

Then Check wheather IDD_SHUTDOWN is defined in Resource.h or not!

It wasn't defined! But now I get lots of errors saying that everything is already defined in a .obj file.

Would any one give me a hint?

I am new to C++ and I am trying to write a small program that would backup an access database file from the hard drive to a zip drive.

I would appreciate any help.

Thank you.

Sounds very much like "do my homework for me please".

But I don't care....

Get a library for creating zip files from the internet, and use it.. that is the rough description of what you have to do.

Sorry I have not been in school for a long time....., I have not used C++ for a few years and was trying to relearn it. I have been trying to figure out how to use the ifstream and ofstream with no luck.

Can't you use CopyFile() or SHFileOperation()? If not, then I guess I don't understand the question. Is there something special about a Zip drive (I've never used one)? Don't you just copy files to it like any other drive?

Nothing special about ZIP drive, except you might (more like probably) get error if no disk is in it. Otherwise, pretty much just like a floppy or any other read/rite drive. I also suspect the CopyFile or SHFileOperation will work just fine.

Hi,
I need to write dll for another MFC application.
I've wrote the dll using MFC DLL wizard (regular dll using shared MFC dll).
In my DLL header there is th followung declarations:

#define TCPDLL_API __declspec(dllexport)
TCPDLL_API int WINAPI FLRInitializeIP(IPStruct *Server,int num_of_radars);

and in my "dll.def" there is the next declaration:

FLRInitializeIP	   @1

Also,the implementation of the function is:

TCPDLL_API int WINAPI FLRInitializeIP(IPStruct *Server ,int num_of_radars)
{
	struct hostent *Host;
	SIZE_T t=100;
	char *host_name = new char[100];
	gethostname(host_name,t);	
         Host = gethostbyname(host_name);
	Server->HostIP = inet_ntoa(*((struct in_addr*)Host->h_addr));
	delete []host_name;
	//Server->ClientsArray = new FLR_COMMUNICATION_DEVICE[num_of_radars];	
         //for(int i = 0 ; i < num_of_radars ; i++)
	//{	
         //	Server->ClientsArray[i].socket = INVALID_SOCKET;	
         //	Server->ClientsArray[i].IP_Address.Empty();	
         //}
	Server->Num_Of_Connected_Clients = 0;
         Server->ListeningSocket = INVALID_SOCKET; 
         Server->Num_Of_Radars = num_of_radars;
	if(CreateTCPServerSocket(Server) != LISTEN_SUCCESS)
		return 0;//LISTEN_FAILED;	          
         return 1;//LISTEN_SUCCESS;
}

Finally,I'm using the dll :

typedef int (CALLBACK* FLRInitializeIP_PROCCESS)(IPStruct* ,int);
void CDLLTestDlg::OnListenButton()
{
    HINSTANCE hLib;
    FLRInitializeIP_PROCCESS FLRInitializeIP;
    IPStruct Server; 
    int result;
    hLib = LoadLibrary("TCP_DLL.dll");
    FLRInitializeIP = (FLRInitializeIP_PROCCESS)GetProcAddress(hLib,"FLRInitializeIP");
    //(FLRInitializeIP)(&Server , 1);
    result = FLRInitializeIP(&Server , 1);  
    m_List.AddString(Server.HostIP);
    FreeLibrary(hLib);
}

Well,I don't get compilation errors,but if the return value
of FLRInitializeIP() is anything else but "void"- i get run time error(something about convention error...).
But, if the return value is "void" there is no error.
When i'm debugging my code - the function works fine and the
error accurs after

return 0

return 1

Can anyone help me with this error?
Is there good tutorial about dll programing?
Maybe I've wrote the wrong DLL project?
