This is ridiculous. You use SDL just to display images from a camera ? Why don't you use another technique (don't know which one but this looks like a very bad solution to me).

Did you even bother to follow the links I gave you ? One of the link describes how to render SDL surfaces in a win32 environment.

Help! How to get Windows installation key

I am trying to get the Microsoft Windows installation key (the serial number) in my VC6 C++ program. The key can be found from XP->Control Panel->System->General. For example, the key on my computer is "55276-OEM-0011901-00102". Does anybody know how to get the string in C++ program?

Thanks in advance

~~//how about using GetVolumeInformation() .~~
Viorel is correct.I checked it with MSDN

Somethings seem HARD to do, until we know how to do them.

I think GetVolumeInformation actually returns another kind of information -- the disk's serial number (the same which is shown by the vol command).

If you are familiar with Windows Management Instrumentation (WMI), then you can obtain the Serial Number through the Win32_OperatingSystem WMI class, which has the SerialNumber data member as a string.

See Win32_OperatingSystem class and WMI-related information.

Thanks a lot!

Here is the actual code I figured out to access the ProductID:

UCHAR buf[256];
ULONG size = 256;
ULONG type = REG_SZ;
HKEY hKey;
RegOpenKeyEx(HKEY_LOCAL_MACHINE, L"SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion", 0, KEY_READ, &hKey);
RegQueryValueEx(hKey, L"ProductId", NULL, &type, buf, &size );
RegCloseKey(hKey);

Great. The only change I would suggest is:

ULONG size = sizeof(buf);

That way if you need to change the size of buf, you only have to do it in one spot.

It should be considered that another sibling key path -- "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ProductId" -- seems to be more version-independent.

The General tab of the System Properties dialog does not look at that key.

Hi I am working with dialog based application. Below is the snapshot of first part of dialog class of my project.

class CFileSenderDlg : public CDialog<br />
{<br />
// Construction<br />
public:<br />
	CFileSenderDlg(CWnd* pParent = NULL);	// standard constructor<br />
	void setStatus(CString);				// function to set status string<br />
	// Dialog Data<br />
	//{{AFX_DATA(CFileSenderDlg)<br />
	enum { IDD = IDD_FILESENDER_DIALOG };<br />
	CString	filePath;<br />
	CString	status;<br />
	//}}AFX_DATA<br />
<br />
	// ClassWizard generated virtual function overrides<br />
	//{{AFX_VIRTUAL(CFileSenderDlg)<br />
	protected:<br />
	virtual void DoDataExchange(CDataExchange* pDX);	// DDX/DDV support<br />
	//}}AFX_VIRTUAL

and so on.

But i am recieving an error on
enum { IDD = IDD_FILESENDER_DIALOG };

And that is
error C2065: 'IDD_FILESENDER_DIALOG' : undeclared identifier
error C2057: expected constant expression

Can anyone please tell me why this error occurs.
Thank you

Thanks for responding. I tried it but now it is displaying "Debug Assertion Failed" dialog. and when i try to debug it, it is at following line in afxwin1.inl

_AFXWIN_INLINE HINSTANCE AFXAPI AfxGetResourceHandle()<br />
	{ ASSERT(afxCurrentResourceHandle != NULL);

Can you please tell me why it is.
Thank you

This is just a guess, but are you trying to create the dialog in some other class's constructor? (My guess is the CWinApp-derived one). If that is the case, then put it elsewhere.

this is this.

This may due to incorrect sequence of including of headers Unsure | :~

Include the resource.h into application's class Header...
This may resolve the problem.

I have made my project using MFC AppWizard so resource.h was automatically included.

Didn't you use ClassWizard to create the project, or the CFileSenderDlg class? It would have handled the resource.h file for you. Otherwise, you'll need to look in that file to make sure there are no duplicate IDs.
