when you develop an SDI Application, you get a default menu. In the File menu there is an option to open the file.

thanks but if i want to modify default menu according to my needs then where can i do it.
|
|
|
|

Document class 
Inside the OnOpenDocument().
|
|
|
|
|
i m using vs 2005 and there is no onopendocument() i think.
|
|
|
|
|
// ClassWizard generated virtual function overrides
//{{AFX_VIRTUAL(CPEWatcherDoc)
public:
virtual BOOL OnOpenDocument(LPCTSTR lpszPathName);
//}}AFX_VIRTUAL
Do u tried to add the code?
I never used vs2005, so i can only guess, they didnt removed it.

HI, i am having problem with converting my c++ class to dll. The problem is the following.
i have a class that i want to export, there are two private variables in the class, one of them is
a struct. the variables are initialized in the constructor. In my ap, i created a object of my class and then delete it. Looks pretty straight forward, however, when deleting the object i get a error message "Debug Error". If i don't initialize the variables, delete is ok. if i memset the struct variable,i get a "scaler deleting destructor" error. Anyone got any idea why the dll behaves like this?
----------------------------------------AP------------------------------------
CIPCamDll *a = new CIPCamDll();
delete a;
---------------------------------------.h--------------------------------------
#ifdef IPCAMDLL_EXPORTS
#define IPCAMDLL_API __declspec(dllexport)
#else
#define IPCAMDLL_API __declspec(dllimport)
#endif
typedef struct s
{
int abcd;
}s;
class IPCAMDLL_API CIPCamDll {
public:
CIPCamDll(void);
CIPCamDll(char* para_address);
~CIPCamDll(void);
private:
int session_id;
s m_t;
};
--------------------------------------------------------------------------------
--------------------------.cpp---------------------------------------------------
CIPCamDll::CIPCamDll()
{
session_id = 13;
return;
}
CIPCamDll::CIPCamDll(char* para_address)
{
return;
}
CIPCamDll::~CIPCamDll()
{
return;
}
------------------------------------------------.cpp-------------------------------

HI, thanks for the reply, i put the memset in the constructor.
i am guessing that it has something do to with different heap memory allocated for
dll, and AP?
--------------------------.cpp---------------------------------------------------
CIPCamDll::CIPCamDll()
{
memset(&m_t,0,sizeof(s));
session_id = 13;
return;
}
------------------------.cpp------------------------------------------

Make sure your exe and dll use the same variant (static/dynamic linking) of the C run-time library.

Are u sure you can compile Windows kernel?
And i dont think you can create the windows GUI directly with a VGA using tc3.0
Windows actually works on wrapper code written on VC++ over the lower layer driver and C++ code.
Yes you can create those but it will take a lot of effort.
i.e you have a write wrapper

What does this message mean in a debug mode?
First-chance exception at 0x5d0c373e in DemoKey.exe: 0xC0000005: Access violation writing location 0x004456ec.
I get this when I am exiting my application which is property sheet based?
 What have I not done before exiting the application or is it Normal?
Thank in advance

Did you use of pointers in your program?
|
|
|
|
|
|
Use of invalid pointer.
Pointer which is deleted most probably
so once you delete a pointer
intialize it to zero.
|
|
|
|
|
I get this when I am exiting my application which is property sheet based?
So why on Exit and not before?
|
|
|
|
|
when exiting, it deleting some pointer which is already deleted.
Check all the pointers.

You are trying to write at an invalid memory location. On of the main cause of this problem is that you are accessing an object which has been released (but there could be other reasons too). If you want to find the cause of the problem and fix it, you'll need to use your debugger to track down the problem.

Hi
I read a Byte array from a file. How can I convert this array to BITMAPFILEHEADER struct?
Best regards,
|
|
|
|
|
Assuming the contents you have read into the byte array will fit into a BITMAPFILEHEADER structure,
BITMAPFILEHEADER* pFileHeader = reinterpret_cast<BITMAPFILEHEADER*>(byteArray);

First you have to make sure that file format confroms to the BITMAPFILEHEADER structure.
If you've, for instance, raw bites of an image, then you've to programatically create an appropriate BITMAPFILEHEADER for the data.
