I use Visual c++ 6.0, I don't know why,
I can't call this function.
But I already try follow "Rinu_Raj" and "programm3r" by use
CString::Getbuffer()
as..
char Del[]=",";
char *str,*buff;
CString buffer,data[3];
buffer="aaa,bbb,ccc";
str = buffer.GetBuffer (10);
buffer.ReleaseBuffer ( );
buff = strtok(str,Del);
data[0] = buff;
buff = strtok(NULL,Del);
data[1] = buff;
buff= strtok(NULL,Del);
data[2] = buff;
TRACE("backup[0]=%s\n",data[0]);
TRACE("backup[1]=%s\n",data[1]);
TRACE("backup[2]=%s\n",data[2]);
I confuse the input parameter of Getbuffer().
I try to change it to 1,10,100,1000 it still can use no problem.
How much value I should be use
and
What does this parameter mean?

That won't work. Once you use ReleaseBuffer, the pointer isn't valid.
Since you're using a single character delimiter, you could use AfxExtractSubString instead.

try this, if satisfies your need. Use sTemp to assign to array.
int nIndx=0;
CString sTemp;
while(nIndx != -1)
{
int nTemp=s.Find(",",nIndx);
if (nTemp==-1)
{
if (nIndx !=0)
{
sTemp=s.Mid(nIndx,(s.GetLength()-nIndx));
}
break;
}
sTemp=s.Mid(nIndx,(nTemp-nIndx));
nIndx=nTemp+1;
}

Use AfxExtractSubString() instead.

Example below which is helps to make use of strtok
eg.
char *szSep="\";
char *sDest=NULL;
char *szChar=NULL;
CString sString="Hell0\Word";
sprintf(szChar,"%s",sString);
sDest=strtok(szChar,szSep);

don't mix C and C++ 
there are whatever you want in the C++ libraries.
also, read the previous answers...

You don't expect this to work, do you?

You do NOT want to pass in a CString's buffer to strtok. strtok changes the buffer it operates on. Thus, if you pass in the buffer returned from GetBuffer, it will change it and the original CString object will be invalidated (that is, the data will be changed) when you call ReleaseBuffer. Looking through what you want to do, just use something like:
void Split(CString strText, CString strSeparators, CStringArray& strArray)
{
int start = 0;
while (start >=0 && start < strText.GetLength())
{
int stop = strText.Find(strSeparators, start);
if (stop < 0 || stop > strText.GetLength())
stop = strText.GetLength();
strArray.Add(strText.Mid(start, stop - start));
start = stop + 1;
}
}
The strArray parameter will hold the values you are looking for.

I want to remove the Titlebar of a SDI FrameWnd class.
could you please tell me which style should I specify?

Remove the style WS_CAPTION
|
|
|
|
|
BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
if( !CMDIFrameWnd::PreCreateWindow(cs) )
return FALSE;
cs.style = WS_VISIBLE | WS_THICKFRAME;
return TRUE;
}
I specified the above code in the precreate Window function. But it is not working for me.

Use ModifyStyle(WS_CAPTION,0); in OnCreate instead.

Thanks for your reply.
we need add one more tweak to avoid painting problems.
The following code worked fine for me.
ModifyStyle(WS_CAPTION,0);
SetWindowPos(NULL, 0, 0, 0, 0,
SWP_NOZORDER|SWP_NOMOVE|SWP_NOSIZE|SWP_NOACTIVATE|
SWP_DRAWFRAME);
-Sarath.

you can mention this as third parameter of ModifyStyle. You need not call SetWindowPos
|
|
|
|
|
I forgot it  Thanks
Anyway those flags need to be called

Which means what exactly? Does the frame window still have a titlebar?

hi
Application in release version is working fine but crashing in debug version.
I think its because of ASSERT statement.
Does any one has a clue?
TIA
|
|

|

Use your debugger to locate more precisely the problem.
EDIT:
Yes, ASSERT wroks only in debug mode but if something asserts, it means that something is going wrong.
|
|
|
|
|
Where it is crashing ?
Please show the code where it is crashing

Its a switch statement with diff cases:
pseudo code:
switch(text)
{
case1:
Do something...;
case 2:
Do something..;
default:
ASSERT(FALSE);
}
Its going to default case and then assert statement is excuting and it crashes here.
Its giving error
"A breakpoint has been reached.
(0x80000003) ocurred in application at location 0x7c901230"
