It seems I need some sort of ratio conversion between logical and physical pixel inside OnPrepareDC. I just can't figure out how to do this. Can anyone help me please?

You can ownerdraw the header control. But before that you must subclass the header control.
First get the header control and subclass it. Use CListCtrl::GetHeaderCtrl() for this purpose.
Read this[^] for more info.

Create customized HeaderCtrl class Say MyHeaderCtrl then create a member variable of this is in class of Listcontrol ,Then override the InsertColumn(...) there do the following code
InsertColumn(...)
{
CListCtrl::InsertColumn(...)
CHeaderCtrl *pHeaderCtrl = GetHeaderCtrl();
if(( 0 != pHeaderCtrl ) && ( FALSE != IsWindow( pHeaderCtrl->GetSafeHwnd())))
{
HeaderCtrl.SubclassWindow( pHeaderCtrl->GetSafeHwnd()); // HeaderCtrl is the member variable of type MyHeaderCtrl
}
........
}

I'm working on a project where the settings will be stored to and loaded from a file on disk. The registry is unsuitable since I want these settings to be distributable and easy to be modified by a user.
I have worked with INI files many times and found them to be suitable for very simple data (like the registry), also they are easy to read (by eye) and edit. However I have noticed that quite a few apps these days are using XML files. I have never used them in an app before but it looks simple enough. So I was wondering what other coders would prefer to use, especially for the type of app as described above.

INI files are arguably more human readable, but an XML file is able to describe things better and is less prone to typos. If someone makes a mistake with an XML config, odds are it just won't load.

Wow, "... and the medal for fastest response..."
The files I am going to create will be a set of rules for a game. Since the game would eventualy be Multiplayer, it is important to quickly be able to share the same set of rules. I'm tempted to go with XML simply because I didn't do it before.

The same holds true for .ini files.

What he means is that it will fail to parse. An INI file will still load, but you will get invalid data back when calling GetProfileString/Int/etc at some point.

Typically, I would use XML. I used INI before but in some case it is quite limited.
I use a nice library, it's called tinyXML[^]

Thanks for the link. I was tempted to go with one those here on CP, but since this one comes recommended, and it's on SourceForge (always a good sign) I will use this one.

I agree with Cedric XML is better

INI is old and outdated, but is useful for simple data (strings, integers).
XML is expensive to parse, but does offer the ability to do preliminary type-checking during the parse, as well as schema validation. This is very useful for complex data types.

1)Read the string from CEdit using the GetWindowText.
2) Read the entries from the database.
3) Compare both these values.
if these values match do something...
Somethings seem HARD to do, until we know how to do them.

i have try this :
CString sEdit1,sEdit2;
m_edit1.GetWindowText(sEdit1);

if(sEdit1 == pName->m_name)
{
m_edit2.SetWindowText(pName->m_city);
}
yes it works but i have 260.000 records and i have to wait about 6 min. to have an answer !!!!!!

See what just Christian Graus said. You can search for the string in the database that is in the edit box, Create a database query and then fire it...
Thanks...Christian. I just missed that point...

This would require reading all rows from the table.  Yuck!

yeah , I very well know that. I replied back with some changes and I guess you didn't read it before posting this one...

Do not read the database and compare values in code, write a select statement for the DB that uses the string from CEdit1, so it only returns the match.
