I have a struct under CDoc

struct MyStruct {
float x;
float y;
};

I use it for CArray<mystruct,mystruct>. I dont know how to define a public variable with struct.

Thanks

You need to put the struct in a .h file by itself. Then each of the .cpp or .h files that need it can simply #include it.

mystruct.h:
 
struct MyStruct
{
    float x;
    float y;
};
 
typedef CArray<MyStruct*, MyStruct*> MyStructArray;

Now the view and the dialog can each have a MyStructArray member variable.

There are quite a number of errors:

typedef CArray<codata*, codata*=""> MyStructArray;

error C2143: syntax error : missing ';' before '<'

So, after I construct mystruct.h, I can add Add Member Variable (public) for Variable Type (MyStructArray)?

Besides, I always get error on CDoc* GetDocument(); in my CView.h.

CArray requires afxtempl.h to be included. I would suggest doing so in the project's stdafx.h file.

Hi
The CDoc* GetDocument(); error is not solved yet. It only happens when I included my CView.h into the cpp.

Thanks

What file are you including CView.h in? I would hazard a guess that you also need to include the CDoc.h file right above that statement.

as i don't really understand your question, my answer is probably off-topic... if so, please reformulate better.

did you try sscanf() with %X in the format ?

CString str = <font color=#808080>"5F6A"</font>;
<font color=#0000FF>int</font> i = 0;
sscanf((LPCTSTR)str, <font color=#808080>"%X"</font>, &i);
 
ASSERT(i == 0x5F6A);

SDK stands for Software Development Kit. Any manufacturer can provide SDKs for its products. They consist of libraries of functions that perform particular tasks. You can use them in your own applications.

Hi,
Am a systems programmer.
I just wanted to know a sample code in c/c++ which can be compiled in vc++ environment.
The code sould be able to accept just the DSN username and password and should be able to connect to the database.
And the possible APIs that can be used for result sets,
using and executing queries.

First create a working DSN using the ODBC applet in Control Panel. Then use AppWizard to create a new SDI (or MDI) project. When asked for database support, select the DSN that you just created. All the right files and classes will be created for you.
