Re: VC++ 6.0 - No Unicode in debug output window

13-Jul-09 2:35

You're welcome, Marcus. Have you tried setting a valid Russian Unicode font as the default font for debugger output window? (I'm assuming that the language is installed on your machine, because you say it appears properly on a message box).

I tried all fonts that I can select in VC6's settings but none did the trick. Is there a way to add new fonts? I never figured out how to do this...

Kind regards

Monitoring Window Creation in another Process

Is it possible to write a program that monitors dialog creation in all processes and auto-fills some edit controls when a particular dialog is detected?

I have an application that prompts the user to login. I also know where the login details are stored so I'd like to be able to auto-fill the username and password controls whenever the login dialog is created. I'm trying to avoid building a back door into the application that could be exploited by end-users.

No, you don't need hooks.

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.

Little things like using KEY_QUERY_VALUE instead of KEY_ALL_ACCESS when applicable.
