is there any function to make the string lowercase before comparing..say
string a="HI How R U"
if(a.find("hi")) //here I want to convert the string into lowercase n compare with lowercase hi
{
cout<<"found";
}
thanks

You can maybe try this function StrStrI. It's takes two buffers look up MSDN. So when you call this function pass in std::string likewise...
StrStrI( &Myword[0], "TaG" );
If successfull it will return address of the substring, else NULL.
Header to include: Declared in Shlwapi.h.
Import Library: Shlwapi.lib.
Also make sure you don't modify the length of Myword buffer. std::string is not aware of any such updates.

thanks for your reply...
Actually if you dont mind I need little more clearence.
I didnot get how do I use strstrI in the same line
if(myword.find("Tag")!= string::npos)
All we need is to incorporate case insensitive search in the same statement above.
(Or can we pass the lowercase of myword itself so that we can check with "tag" always)...something like
if(lcase(myword).find("Tag")!= string::npos)
myword is of the type string
thanks in advance

Like this...
if( StrStrI( &Myword[0], "Tag" ))
{
MessageBox( "Found \"Tag\" in Myword :)" );
}

Hello everybody,
does exist a handler which indicates the end of the maximization code?
Because if I maximize the MDI-Frame i step 4 times into the OnSize Handler of the Frame and its View.
Each time the View is calculated at new, which provokes a ugly effect (+- flickering)
If I get the OnSize Handler for maximization, i could freeze the View or Screen. And after the last OnSize i release the Screen.
But I don't find a way to detect the end of this maximizing process.
Is there already a technique to work arround?
Big thanks for any help

Hi all,
I am trying to extend a NTFS partition using FSCTL_EXTEND_VOLUME. The code is
HANDLE hVolume = CreateFile(L"\\\\.\\E:", GENERIC_READ | GENERIC_WRITE,FILE_SHARE_READ|FILE_SHARE_WRITE|FILE_SHARE_DELETE,NULL,OPEN_EXISTING,0,NULL);
LONGLONG liBuffer = 20971520; // size in sectors to be increase
DWORD dwReturnedBytes = NULL;
DeviceIoControl(hVolume,FSCTL_EXTEND_VOLUME,&liBuffer,sizeof(liBuffer),NULL,0,dwReturnedBytes,NULL);
But the function fail with #error 87.
Someone please help me out with your suggestions.
Thanks.

FormatMessage()[^] says: "The parameter is incorrect". So, you could check if all the parameters are valid before you pass it to the function.
You could as well use the Error lookup utility which comes with VS to get the error description for an error number.

Thanks for the reply.
Yes all the parameters are correct. Is there some extra job need to do before executing this function?

Hi Madan Chauhan,
Only FSCTL_EXTEND_VOLUME is not sufficient to extend any NTFS volume. You need to first extend its boundry then use this control code.
thanks

Thanks for your guidance.
I dont have any idea which API or function extend the boundary of partition.
Please tell me if you know that one.
thanks.

Hi all,
I'm having an application for Remote control, but there are some problems in its part of network connections.I have tried for weeks, still can't find out the reason for that.
In our program, we don't use thread synchronization in function "TCPSock->Recv"(winsock api recv() is used in it), because this function is only used in single thread. Today, I tried to add thread synchronization to this function.As a result, these network connections problems are fixed(at least it seems to be).
My question is, "Is thread synchronization needed when only using a function in single thread?"
Regards,
HQ

It is actually the other way round. If you are using multiple threads, then you try to synchronize access to the code that must be protected from multiple simultaneous accesses.
Or is that you are referring to an additional worker thread (other than the application's main thread) while saying a "Single thread"?

Thanks for your replay
Yes, I mean "an additional worker thread" when I say "a single thread".
Our program mainly has two parts, server and client.
server accepts connections from client, when a connection is accepted, it creates a "worker thread" to communicate with the client. Only in this thread, "TCPSock->Recv()" will be called, so originally we don't use a "Thread Synchronization". But today, I Added "Thread Synchronization", and the bugs seem to be fixed, so I want to know "Is Thread Synchronization needed in single thread in some conditions?"
Thanks very much

Glad about that.
hanq_38910130 wrote: "Is Thread Synchronization needed in single thread in some conditions?"
But, I still am not able to understand this. If it is just one thread accessing the code that must be 'protected', then it does not matter how many other threads are running simultaneously. But if more than one thread can possibly access the code that must be protected, then you need synchronization. I hope I am clear.
There is a whole lot of information on this topic here[^] if you would like to read up.

 Thanks for your help.
I will look into the linking which you provided to see if there can be any useful information.
Add maybe the reason that causes all these problems exist in some other code, anyway I will check this.

Hello,
class CRICH : CRichEditCtrl
{
afx_msg void OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags);
afx_msg void OnKeyUp(UINT nChar, UINT nRepCnt, UINT nFlags);
afx_msg void OnLButtonDown(UINT nFlags, CPoint point);
};
I have 5 CRICH boxes on CMDIChildWnd which are shown properly with a cursor in the first box . That is it has focus but once if I press a mouse cursor on the box the cursor disappears and none of the boxes has focus.If I click the mouse on the box LButtonDown message handler is not called.
What must be the problem ? thanks
Prithaa
