Microsoft's WAV file format is well documented.
A quick GOOGLEY search found this one

By the way, FCC() is just somebody's function for dealing with FOURCC codes - four characters
which need to be written in order in a big-endian/little-endian integer world.

Is there any problem in reading line by line or character by character,
while (input.good())
{
input.getline(tmp ,255);
cout<<tmp <<end;
}
|

Hi,
In case of >> operator, string is extracted up to the first whitespace character, and that's why you can't read entire string.
Use getline instead.
working example:
const int slen = 256;
char tmp[slen] = "Sit on my face...";
ofstream ofile("c:\\test.txt", ios::out);
ofile << tmp << endl; ofile.flush();
ofile.close();
char tmp2[slen];
ifstream ifile("c:\\test.txt", ios::in);
ifile.getline(tmp2, 256);
cout << tmp2 << endl;
ifile.close();
Regards

I was trying to change the font of some labels on a dialog, I used the following code:
HBRUSH CTabOne::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)<br />
{<br />
<br />
<br />
HBRUSH hbr = NULL;<br />
CFont LabelFont;<br />
if(nCtlColor == CTLCOLOR_DLG || nCtlColor == CTLCOLOR_STATIC)<br />
{<br />
if(pWnd->GetDlgCtrlID() == IDC_STATIC_COMMAND)<br />
{<br />
LabelFont.CreateFont (14,14,0,0,FW_BOLD, FALSE, FALSE, 0, DEFAULT_CHARSET,<br />
OUT_CHARACTER_PRECIS, CLIP_CHARACTER_PRECIS, DEFAULT_QUALITY,<br />
DEFAULT_PITCH, NULL);<br />
pWnd->SetFont (&LabelFont, TRUE);<br />
}<br />
}<br />
return hbr;<br />
}
And included
ON_WM_CTLCOLOR()
in the message map.
But looking at the processing that is being done ~ 50%, I have got something wrong! Also the labels 'flicker'.
As these are static labels, just need the Font set during dialog initialsation.
A bit confused as to how to set up the OnCtlColor parameters if thats the way to do it.
Any suggestions please.
Andy.

Why dont you use CWnd::SetFont() for this purpose? Instead of above code.
|
|
|
|
|
Hi,
instead: pWnd->SetFont (&LabelFont, TRUE);
use: pDC->SelectObject( LabelFont );
and don't forget about delete font object
LabelFont->DeleteObject();
Works pretty good

Why?
SetFont can be called from OnInitDialog. As it needs to be set once. Why you want to set it again and again.(it will be called each time window is painted).
|
|
|
|
|
OK, that sounds good just setting it once.
But how do I select the control I want to change the Font in OnInitDialog?
I was selecting the ones in the OnCtlColor procedure.
Andy.

Hi,
GetDlgItem( IDC_STATIC_COMMAND )->SetFont( &LabelFont, TRUE );

CWnd *pWnd=GetDlgItem(IDC_STATIC);
pWnd->SetFont();

Thanks Prasad, all working as required.
Using this I can make my Dialogs a bit more interesting.
est wishes,
Andy.

Hi,
Yes you're right, it can be used with CWnd::SetFont.
I wrote only a little correction to Andy202s code

If you have a variable for their you can use of m_Static.SetFont(GetFont());

 The situation is :
-launch of release application using my COm object => memory leaks when I use Function to get data with an SafeArray.
- launch of release application in VC++ 6.0 with debug => no memory leak.
What is the difference, what are dll that are used? Have someone an explication?
Thank you for a response and help

Hi,
For some odd reason, I am not able to Register the COleDropTarget.
I have been working with my project for a while, so I suspect it is
something within my project.
I do have the member variable COleDropTarget m_dropTarget in the header.
Then, in the OnInitialUpdate, I call m_dropTarget.Register(this).
// register drop target
BOOL b = m_dropTarget.Register(this);
It keeps failing at the if(CoLockObjectExternal()) shown below.
Does anybody know what CoLockObjectExternal means?
BOOL COleDropTarget::Register(CWnd* pWnd)
{
ASSERT_VALID(this);
ASSERT(m_hWnd == NULL);
ASSERT_VALID(pWnd);
LPUNKNOWN lpUnknown = (LPUNKNOWN)GetInterface(&IID_IUnknown);
ASSERT(lpUnknown != NULL);
if (CoLockObjectExternal(lpUnknown, TRUE, FALSE) != S_OK)
return FALSE;
