What's the type of m_bmpCtrl variable? There will be direct functions exposed in the class to clear the attached resources
also the way you released the resources is quite wrong. if you're explicity releasing the resource, it's your responsibility to assign it as NULL. Otherwise the next call this function may crash, as you've released the previously and the m_bmpCtrl.hBitmap still holds an junk(invalid) handle. also why it's necessary to create a temporary variable? the following way is straight forward no?
if (m_bmpCtrl.hBitmap)
{
DeleteObject(m_bmpCtrl.hBitmap);
m_bmpCtrl.hBitmap = NULL;
}

Thank you. That has partly solved it. Yes there was no point creating extra variable.
The m_bmpCtrl is of CBitmapCtrl class.
I am new at this and am learning. Thanks for all your help It's greatly appreciated.

I need logic for finding folders including subfolders within a selected path.

There are no less than a thousand examples of this on the Web. Search for FindFirstFile(), CFileFind, or _findfirst().

I have an client application which as files i need to copy the a selected file into clipboard and paste it on the desktop or any where outside my client application
Within my client application i am able to copy and paste files but not outside my client application.
Here is the code
void SetClipBoardStringData(CString str, int format )
{
EmptyClipboard();
CString text = str;
HANDLE hGlobalMemory = GlobalAlloc(GHND, (DWORD)(text.GetLength()+1));
HANDLE lpGlobalMemory = GlobalLock(hGlobalMemory);
memcpy(lpGlobalMemory,(text),(text.GetLength())+1);
SetClipboardData(format,lpGlobalMemory);
GlobalUnlock(lpGlobalMemory);
GlobalFree(hGlobalMemory);
}
I am calling this function.
SetClipBoardStringData(sStrXML,CF_TEXT);
This copies the sStrXML to the clipboard.This sStrXml contains the file contents.
Now i want this clipboard contents to be availale outside the application so that i can paste it another application like notepad or a file in desktop.
How do i do it?

Try passing hGlobalMemory instead of lpGlobalMemory in SetClipboardData function.

Can we use SetLocaleInfo for non-union code to support unicode strings.
If, so please give me an example not declaration.

Why not?

Ummm - access permissions?
You know, most Windows functions return error codes and set the thread's error status (see GetLastError[^]), just so that you can tell why failure's occurred....

Actually I want to make the Key as shared key, That will be accessible by 32 and 64 bit both application.

KarstenK told you that there are separate 32- and 64-bit registries. That says to me that your desire isn't going to be fulfilled. Get over it and use a file instead - I believe Microsoft kind of recommend using files for configuration information (rather than the registry) these days.

I think we can use symbolic link insted of shared link.

Hello
I am beginner in VOIP.I try to make simple calling and answering application.
Here i face this problem -I can hear only one side(calling).
Please check this following code.
//Calling-Ip Calling Function
gpAddress->CreateCall(bstr,LINEADDRESSTYPE_IPADDRESS,TAPIMEDIATYPE_AUDIO,&gpCall);
hr=SelectTerminalsOnCall(gpCall);
hr=gpCall->Connect(0);
//Answer -I add Answer method in event.
LRESULT CVOIPCallDlg::OnTAPIEvent(WPARAM wParam, LPARAM lParam)
{
CString csName;
switch(wParam)
{
case TE_CALLNOTIFICATION:
{
AddLog("call notification event has occured");
// Get the ITCallNotification interface.
IDispatch* pEvent=(IDispatch *)lParam;
Answer(pEvent);
}
break;
case TE_CALLSTATE:
ITCallStateEvent *a=(ITCallStateEvent *)lParam;
ITCallInfo *b;
if(a->get_Call(&b) != S_OK)
AddLog("get_Call()",hr);
CALL_STATE pCallState;
if(a->get_State(&pCallState)!= S_OK)
AddLog("get_State()",hr);
switch(pCallState)
{
case CS_INPROGRESS:
AddLog("dialing");
break;
case CS_CONNECTED:
AddLog("Connected");
break;
case CS_DISCONNECTED:
AddLog("Disconnected");
break;
case CS_OFFERING:
AddLog("A party wants to communicate with you!");
break;
case CS_IDLE:
AddLog("Call is created!");
break;
}
break;
}
pEvent->Release();
return 0;
}
LRESULT CVOIPCallDlg::Answer(IDispatch* pEvent)
{
HRESULT hr;
ITCallNotificationEvent * pNotify;
pEvent->QueryInterface( IID_ITCallNotificationEvent,(void **)&pNotify);

ITStream * pStream;
hr = pStreamControl->EnumerateStreams(&pEnumStreams);
pEnumStreams->Next(1, &pStream, NULL);
long lMediaType;

hr = pTerminalSupport->GetDefaultStaticTerminal(lMediaType,dir,&pTerminal);
hr = pStream->SelectTerminal(pTerminal);
hr = pBasicCall->Answer();
return hr;
}
Can you help me how it resolve.
Thanks

Hi ,
When i try to do as follows.
CString strString=_T("testing");
int nSize=sizeof(strString);
now nSize gets a value =4;
how the size is getting 4 strString is a pointer..? i guess it is an object...
Please clarify..

Yes... 
If you look into the code of CString you will get the answer.
- ns ami -
|
|
|
|
|
then why the size of CString is 4..?
|
|
|
|
|
The size of a class object is the sum of size of all the non static members. If you check the CString class (as I told before) you can find only one member inside it. ie., LPTSTR m_pchData;

thanks for a convincing explanation.
actually i got carried away by some other false assumption.

No need to guess: CString is a ATL/MFC class [^]. A class instance is an object.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

CString is an object which has some methods as GetLength() which will return the lenght of the incorporated string.
Plaese clarify your question...

We have non-unicode application where it has to support different language strings like korean, chinese etc.
I had installed the required language packages. I have to change the language dynamically through a menu item.
Until unless teh language settings have been done in regional/language settings and reboot the machine the language strings doesn't change. Is there any way to by-pass teh reboot so that I can update the required registry values for changing different language???
Even there's The Microsoft AppLocale Utility for this but I shouldn't use that utility in my application.
Please post your views
