Why the base::fun1() is needed ?

If the fun1(int i) is not there then there is no error.
Once the overload function is declare its giving the error.

Did you even read my answer? To repeat what I said - the error's because fun1 in derive hides the definition of fun1 in base. It (fun1 in derive) is not an overload, because it's defined in a different scope than fun1 in base.

With your fun1(int) in derived class you're hiding the base class fun1. See here [^].

I'm sorry but I don't understand anything of the second part of your sentence. What is a tabla, a talla and a laya ?
Please, when asking a question keep in mind that we don't have any idea of what you are trying to do. So, try to be as clear as possible when asking your question.

Hi Cedric,

Tabla[^] is an Indian musical instrument.

Taala and Laya are related with music. To be precise,

taala: the beat set for a particular composition (a measure of time). taaLas have cycles of a defined number of beats and rarely change within a song.
laya : The term for tempo in Indian music.

Now please answer the guy. Big Grin | :-D

Regards,
Jijo.

CRichEditCtrl::StreamOut property

Hi .. I am using CRichEditCtrl::StreamOut function to get the rtf of richedit control in cstring variable, but its not returning multibyte character(chinese, korean)which i entered as text in richedit control. Is there any flag needs to be set to get this values.
Thanks

This worked for me:

DWORD __stdcall EditStreamCallback(DWORD_PTR dwCookie, LPBYTE pbBuff, LONG cb, LONG *pcb)
{
   LPCWSTR a = LPCWSTR(pbBuff);
   // Manipulate a
   return 0;
}

   // In a message handler
   EDITSTREAM es = { 100, 0, &EditStreamCallback };
   rich_.StreamOut(SF_TEXT|SF_UNICODE, es);

The important bit is specifying the SF_UNICODE flag in conjunction with the SF_TEXT flag.

Hi all,

I am trying to use WM_COPYDATA to implement IPC between my global hook dll and my main application. It works well with almost of applications on Vista except IE7 Protected mode. I successed to call ChangeWindowMessageFilter to allow my main application receive this message from lower integrity processes but my main application still could not receive this message from IE7 if it is running in protected mode. Are there anyone who successed in sending message from IE7 protected mode to higher integrity processes? Please help me!

Thank you and regard.

Hi,
I am using visual studio 2006.I have written one function called GetID in
my code.I have enabled Breakpoint in this function.But it is Disabling while debugging.

char* EnhancedReport::GetId(char *fileName,int flag)
{
	char l_ID1[4];
	int k = 0, cnt = 0;
	size_t  fileNamelen =  strlen(fileName);

	for(int i=0; i< (int)fileNamelen-1; i++)
	{
		if('_' == fileName[i])
		{
			cnt++;
		}
					
		if(flag == cnt)
		{
			l_ID1[k] = fileName[i+1];	
			k++;
		}
	}
	l_ID1[k-1] ='\0';
	return l_ID1;	
}

can any one help me.

2003, 2005 or 2008. I never heard about a Visual Studio 2006 (or are you talking about VC6 ?)

Are you sure that you are debugging the debug configuration and not the release configuration ? Make sure debugging information is enabled in your build.

Well, that explains why you don't have brekpoints. No debug information is generated for release configuration.

hemlat wrote:

Each configuration (release and debug) have their own project properties. Thus, you probably added a link setting in your release configuration and forgot to add it also in your debug configuration. MAke sure that everything you added in the release configuration is also added in the debug configuration.

My project is having Breakpoints and I am able to see all breakpoints while debugging except the function which I mentioned.I think If we did any mistakes in code It happens. If I use l_ID1[i] instead of l_ID1[k] (in second If condition of for loop in my function) break points are coming.But I need to put l_ID1[k] in function.

l_ID1[i] = fileName[i+1];
K++;

One problem you've definitely got is that you're returning a pointer to a local array (l_ID1) - that array will not exist after the function returns - I'm surprised the compiler doesn't warn you about it.. I'd suggest you use a managed string (like CString or std::string) instead.
