I have a application which is need windows media player control to play video file.

For that I inserted a Windows Media Player control through Insert ActiveX control in my application. And I Create a variable m_WMPlayer for that media player by Add variable option. Now the system adds a Class called CWMPlayer and adds line of code in DoDataExchange() as

DDX_Control(pDX, IDC_GUI_GAM_TRAILER, m_WMPlayer); // Query1

And I use this m_WMPlayer variable for set URL and uiMode.

m_WMPlayer.put_URL(strTrailerPath);
m_WMPlayer.put_uiMode(_T("mini"));

Here my query is, When I execute the code, The above line (Query1) doesn't create window handle for m_WMPlayer object. CWnd handle still null.

I think you'll find that the media player control is windowless (i.e. it's not contained within its own window). If you use Spy++, I think you'll see there's no window associated with teh control.

The problem is video is playing well but the controls (Play, Stop and volume) doesn't visible. when I move the cursor in Media player control the tooltip text show "Play", "Stop", ...

Can't duplicate that - I get the controls on an instance of the Windows Media Player that I've added to a sample dialog app.

I even tried setting the control's uiMode property to 'none' in the designer and 'mini' in the dialog's OnInitDialog, to see if that caused issues, but it worked as expected, with the player's controls being displayed.

Hi , i have developed a program to read registry from local machine,now when i run the exe in a machine which is logged in as admin then my exe gives correct value but when i run in a machine that do not logged in as a user which is not part of admin group then i cannot access to registry why it so.

If i use wmi to read registry then will the above problem get solved ???

This is a Vista related issue, I suppose. A program having 'standard' user privileges can only access the HKEY_CURRENT_USER tree, as far as I know.

No i am running in windows xp network and i am reading this key

HKEY_CURRENT_USER\\Software\\Policies\\Microsoft\\Windows\\Control Panel\\Desktop\\ScreenSaveTimeOut

This key is set through group policy by the system admin for a particular domain but i am unable to read this key in non admin rights , but in admin rights i can read this key.

Why it is soooooooooo ??

Below is my code

void GetScreenSaverTimeOutInfo()
	{
		try
		{
			HKEY hKey;
			strCategory=SysAllocString(L"ScreenSaverInfo");
			strItemName=SysAllocString(L"ScreenSaveTimeOut");
			strInstallDate=SysAllocString(L"-NA-");
			strVersion=SysAllocString(L"-NA-");
			strValue1=SysAllocString(L"-NA-");
			strValue2=SysAllocString(L"-NA-");
			strValue3=SysAllocString(L"-NA-");

			if (RegOpenKeyEx(HKEY_CURRENT_USER, TEXT("Software\\Policies\\Microsoft\\Windows\\Control Panel\\Desktop"), 0, KEY_ALL_ACCESS, &hKey)!=ERROR_SUCCESS)
			{
				WriteToFile(GetNewRow());
			}
			else
			{
				DWORD dwType = REG_SZ;
				TCHAR buf[10] ;
				DWORD dwBufSize = 10;
				
				if( RegQueryValueEx(hKey,TEXT("ScreenSaveTimeOut"),0, &dwType, (LPBYTE)&buf, &dwBufSize) == ERROR_SUCCESS)
				{
					strValue1=SysAllocString(buf);
					WriteToFile(GetNewRow());

					SysFreeString(strValue1);
					SysFreeString(buf);
				}
				else
				{
					WriteToFile(GetNewRow());
				}
				RegCloseKey(hKey);
			}


			SysFreeString(strCategory);
			SysFreeString(strItemName);
			SysFreeString(strInstallDate);
			SysFreeString(strVersion);
			SysFreeString(strValue1);
			SysFreeString(strValue2);
			SysFreeString(strValue3);
		}
		catch(char *error)
		{
			//Release();
			error="Error occurred in function GetScreenSaverSecureInfo()";
			throw error;
		}
	}

It's because that key is protected from user access - registry keys can have permissions and ACLs just like files can. You can see and manipulate those using regedit.

The group policy stuff does a lot of this sort of thing - you'll find even if you change the values under the key, they'll get reset again when you next login.

Of course, open it with KEY_QUERY_VALUE or KEY_READ access rights instead of KEY_ALL_ACCESS.

It's amazing to see how people cannot take care of little things like that. They just throw anything at it and expect it to work. Not to mention they'll blame UAC then. Smile | :)

How to get file record from file name?

I think registry write access will be only available to privileged users. If you want your application to read/write settings under any account then perhaps you should make use of app configuration file to keep track of settings.

Hello everyone:
Disk format is NTFS.How can I get file record like using DeviceIoControl function with the control code FSCTL_GET_NTFS_FILE_RECORD to retrieve the file record?
Any information is appreciated,thanks in advance.

do you mean to say,
you need to pass FSCTL_GET_NTFS_FILE_RECORD to DeviceIoControl to get a record in file?
if so, i remember, there are some in and out parameters in DeviceIOControl,
so you can retrieve the record from a file in your despatch handler code and then pass the structure out to the user layer.
but still, some clarity is required on your post.
