   lpcs->style |= WS_HSCROLL|ES_AUTOHSCROLL;

Unicode problem in richedit

Hi all,
I have a richedit control in my program (which is unicode compiled). This richedit control refuses to display the ALT+nnn codes. Instead some sort of random junk (boxes) appear after I let go of the alt key and press any other key. I load the "RICHED20.DLL" library. Another fact is that i can paste unicode characters in the control. It is only with the typing, that the control seems to have a problem. Any help will be appreciated. Thanks in advance.

Setting System Clock in Vista (&7) - UAC problem

I have written a program (C++/MFC) to obtain the correct time from a time server and set the system clock. Unfortunately, Vista & Win 7 with UAC enabled block this operation. How can I elevate the program's security privledge level so that I can set the clock? Is that the right approach? If not, how else might I go about it? I wouldn't have thought the system time would be that protected, but it obviously is. I am using a Code Project solution CSNTPClient class and the class function CSNTPClient::SetClientTime(CTime newTime) The solution on my own machine is to turn UAC off, but that's not practical or reasonable on other people's computers.

Thanks.
Ron

Do you intend to learn recursions?
You forgot to mention the condition, when would this end!

You need to google first, if you have "It's urgent please" mentioned in your question.

string::find() function for case insensitive search

Hi to All,

I have used the find() function of string lib in my program.
Now my problem is I need to search for case insensitive sub string.
Please help me to convert my code .

My code sample is.........
string::size_type loc=Myword.find("TaG"); //searching if tag/Tag/tAg...is present in the string
if(loc!= string::npos)
{
//tag is present
}
else
{
//"tag absent";
}

thanks in advance

You have two options

Override your own string type that's case insensitive:
Clicky[^]

Or just make lower case copies of the string and substring, and use find with those.

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...

{
   MessageBox( "Found \"Tag\" in Myword :)" );
}

end of maximization of frame

baerten17-May-09 23:28

17-May-09 23:28

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 Smile | :)

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.

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.

About Thread Synchronization

17-May-09 23:16

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?"
