Hello LiYS.
Your second question is already answered, so I will try to answer yor first question.
To be honest, I'm not 100% sure, but my guess is that it isn't possible to open a CDROM-drive in GENEREIC_WRITE-mode.
In my own code, I first try to open the drive in GENERIC_READ | GENERIC_WRITE-mode. If it doesnt work, I try again, in GENERIC_READ-mode.
It seems to work at all times. But of course, if it's possible only to open the drive in GENERIC_READ-mode, then it's obviously read-only.
A comment: You should check your handle for INVALID_HANDLE_VALUE before calling DeviceIoControl.

Use NM_CUSTOMDRAW. Sample for this code will be like this
void MyDlg::OnCustomdrawList ( NMHDR* pNMHDR, LRESULT* pResult )
{
NMLVCUSTOMDRAW* pLVCD = reinterpret_cast<NMLVCUSTOMDRAW*>( pNMHDR );
*pResult = 0;
if ( CDDS_PREPAINT == pLVCD->nmcd.dwDrawStage )
{
*pResult = CDRF_NOTIFYITEMDRAW;
}
else if ( CDDS_ITEMPREPAINT == pLVCD->nmcd.dwDrawStage )
{
*pResult = CDRF_NOTIFYSUBITEMDRAW;
}
else if ( (CDDS_ITEMPREPAINT | CDDS_SUBITEM) == pLVCD->nmcd.dwDrawStage )
{
COLORREF crText, crBkgnd;
crText = RGB(0,255,100);
crBkgnd = RGB(255,32,11);
pLVCD->clrText = crText;
pLVCD->clrTextBk = crBkgnd;
*pResult = CDRF_DODEFAULT;
}
}

whats the best way to read ini files and store the input configuration for a program in a class that will be used throughout the program. I want to have a STL map for each section, and read the name/value pairs in each section into the map. Is this a good way to keep the configuration? What are the other general approaches people follow in keeping the config in memory?
What is the way to enumerate the name/value pairs in a given section?
Does each call to GetPrivateProfile* parse the INI file again? Is this why they take the INI file name as a parameter?
thanks!

Yeah thats the good way! till you ini file info doesn't change between execution of program!

Yeap, you are thinking in right way! it reparse the ini file every time it call it!

With GetPrivateProfileString() and GetPrivateProfileInt().
Lambu Jindu wrote: Is this a good way to keep the configuration?
How often do you need the values? Do you want the values to be able to be changed while your program is running, or must your program be restarted?
Lambu Jindu wrote: What is the way to enumerate the name/value pairs in a given section?
Using GetPrivateProfileSection().

Yes.

Ahh! I am suprisized you did not mention that those functions are only supplied for 16 bit compatabilty and he should be using the registry. (All thou I hope they stick around as I have found them useful for other purposes in the past)
If I remeber correctly, they designed those functions right. When you make a call to one of them, the information is actualy cached so that the second time you call for the same information it is read from the cache, unless the file has been modified between calls (need to be recached).
In other words, they can use the functions you specified directly without having to store the values internaly, as they have already been stored in a cache some where.

How to get the same intensity after stretching an image
eg:
Let intensity of a square of 1 unit = 1 x I1
If I stretch the square to 2 units then the intensity = 2 x I2
Both these intensities should be equal
1xI1 = 2xI2 = k(constant)
It should work ways (ie) the intensity should decrease while stretching and increase while shrinking.
I am using bilinear interpolation for stretching but the intensities aren;t equal.
Is there any algorithm or filter to alter the intensity of an image.
Pls Help
