Oh my God! Is it related to this[^]? If yes, you're doing a terrible thing. Please follow the guidance given to you by Cedric.

Hi,

Thanks & Regards,

Does this GetEnvironmentVariable(/*parameters*/) help

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

Hi,

I am not sure about data type of environment variable, but if you know the data type, you can use CString variable and format it.

Refer here:CString::Format[^]

What compiler are you using?

Suman

I have an application which need to start the audio/video settings on a button click. I have written code for that:
************start of code**********************************************
HRESULT hr = CoInitialize(0);
if (FAILED(hr))//CoInitialize failed
return hr;

//Obtain a pointer to the IUccPlatform interface
//by way of the cocreatable UccPlatform class.
CComPtr <IUccPlatform> pIUccPlatform;

hr = CoCreateInstance
(
__uuidof(UccPlatform),
NULL,
CLSCTX_INPROC_SERVER,
__uuidof(IUccPlatform),
(LPVOID *)&pIUccPlatform
);

if (FAILED(hr))
{
AfxMessageBox(IDS_STR_ERROR_COCREATE_INSTANCE);
return hr;
}

CComBSTR bstrAppName = _T("application");
hr = pIUccPlatform->Initialize( bstrAppName);

if (FAILED(hr))
{
AfxMessageBox (IDS_STR_ERROR_INITIALIZE);
return false;
//device settings
}

CComPtr<IUccMediaDeviceSettings> spMediaDeviceSettingsPtr;
pIUccPlatform->QueryInterface( &spMediaDeviceSettingsPtr );

spMediaDeviceSettingsPtr->InvokeTuningWizard((OAHWND)theApp.m_pMainWnd->m_hWnd, UCCTWP_AUDIO | UCCTWP_AUDIO_NONPRIVATE | UCCTWP_AUDIO_NOTIFICATION);
//AfxMessageBox(IDS_STR_ERROR_INVOKE_TUNING_WIZARD);
pIUccPlatform->Shutdown();

*****************End of Code************************

and as I know we have to add the three dlls(UCCAPIRES.dll,UccApi.dll,RTMPLTFM.dll) in application project, I have done that and I also got success in that. But when I run my application on other system after clicking button to start the audio/video settings I got an error message "Error CoCreateInstance ".
If any idea then please share.

Configuration for apllication is

I'm writing a App to scroll the window which is not foreground with the mouse wheel, And Use the Mouse hook In my code, first i reDirect the message like this:

POINT pt;
::GetCursorPos(&pt);
pMHSEX->MOUSEHOOKSTRUCT.hwnd=::WindowFromPoint(pt); //reDirect

but this do not take effert so i change the code :

POINT pt;
::GetCursorPos(&amp;pt);
pMHSEX->MOUSEHOOKSTRUCT.hwnd=::WindowFromPoint(pt); 
::SendMessage(pMHSEX->MOUSEHOOKSTRUCT.hwnd,WM_MOUSEWHEEL,pMHSEX->mouseData,0);
return TRUE:

this works in many windows (foreground or not foreground with scrollbar inside) when the mouse move on it with the wheel scrolled, these window were all act,but when the mouse move to the IE window with Scrollbar then scroll the mouse wheel it does work Frown | :(

I have searched some article, and some about the window whose class name is "Internet Explorer_Server", and i try to test:

#define ID_IE_ID_ADDFAV 2384
::SendMessage( pMHSEX->MOUSEHOOKSTRUCT.hwnd, WM_COMMAND,MAKEWPARAM(LOWORD(ID_IE_ID_ADDFAV),0x00), 0);

it appear a IE add favorite window, but how do i send a Scroll meesage to this window ?

Can someone help me? Thanks Smile | :)

I have to get the total count of the files present in a folder.I have to do a file transfer from that folder to another on a button click.Any help?Im using vc++

Naveen23-Jun-08 18:50

try FindFirstFile() and FindNextFile() or its MFC wrapper CFileFind to find the number of files in a folder

If you want to copy the entire contents of folder at once use SHFileOperation or if you want to copy one by one, use CopyFile().

Please check my code...

void CMydlgtestDlg::Oncount() 
{
int count=0;
CFileFind f;
CString file="D:\\mframes";
if(f.FindFile(LPCTSTR(file)))
{
	count++;
	f.FindNextFile();
}
AfxMessageBox(count);

Naveen23-Jun-08 19:42

23-Jun-08 19:42

Like this..

int count=0;
   CFileFind f;
   CString file="D:\\mframes\\*.*";
   BOOL bFound = f.FindFile(file);
   while( bFound )
   {
	   bFound = f.FindNextFile();
	   if( !f.IsDirectory())
	   {
		   count++;	
	   }	   
	   
   }

Press the Retry button while debugging and check the call stack to find the assertion location.
