Please, take a deep breath and then try to elaborate your question (if is it a question...) a bit.

If I change style of Combobox to Drop List, its backcolor is changing to grey.

I want Drop List (readonly) with white background same as the one in VC++ for selecting Release/Debug configuration.

Also I would like to have border around it.

How to do this? Any suggestion would be greatly appreciable..

Create a class that derives from CComboBox.
Override the OnCtlColor virtual function.
Check for CTLCOLOR_LISTBOX in the 3rd parameter.
Return the required brush.

In addition to Superman's reply...

1/ There's a reason the colour has changed - the behaviour has changed. By overriding the colour back to white, you are now lying to your users. They will go "ahah, ah enabled box we can type it. Look, it's white!". And then they will get very frustrated. Only override this if you are REALLY sure you can cope with the potential confusion - and people issuing bug reports against you. Or worse - not giving you money.

2/ Don't just go for RGB(255,255,255). What if your customer is stuck in the 70s and likes a green on pink colour scheme? Who are you to say it's ugly? Please pick one of the system colours. That helps you - you can use GetSysColorBrush and be lazy!

Try something like this:

CFont fnt;
LOGFONT lf;
::ZeroMemory(&lf, sizeof(lf));
lf.lfHeight = 14;
lf.lfWeight = FW_BOLD;
::lstrcpy(lf.lfFaceName, "Tahoma");
fnt.CreateFontIndirect(&lf);
GetDlgItem(IDC_STATIC_CTRL)->SetFont(&fnt);
fnt.Detach();

Modifiy lf.lfHeight and lf.lfFaceName to your liking. There are other properties in the LOGFONT structure you might want to modifiy - look it up in the documentation.

The wizard does not like static controls with the ID IDC_STATIC. Sigh | :sigh:

That's reasonable however, since many controls may share the IDC_STATIC identifier.

Wonder why these controls were not given IDC_STATIC1, IDC_STATIC2 etc. like all the other controls.
Unsure | :~

I suppose they (Visual Studio Development team) assume that you usually don't need to identify them (after all they're static...). Probably most users don't care about.

THEY could've avoided a lot of confusion especially with beginners.

Hello Pradeep,

Take properties and change combo type to "Drop List".

Retriving Data from Map

I want to retrive the data from the end in a map.
Generally for retriving we write below code for getting data from begining.

so please suggest how can we get the data from the end in a map???

map<int,cstring>::iterator itera;
for(itera = m_mapFinalSortVirusData.begin();itera != m_mapFinalSortVirusData.end();itera++)
{
int nCount= itera->;first;
CString strvirname = itera->;second;

CString str = "";
str.Format("%d %s",nCount,strvirname);
AfxMessageBox(str);
}

Not exactly correct: when iterating in reverse mode, you should replace the usual begin() by rbegin() and the usual end() by rend(). Thus rend doesn't return you the last element in your map but point before the first element.

Use a reverse iterator: it is the same principle as an iterator, except that it starts from the end of the container. You have to use the rbegin function (which returns the begining of the reverted map, aka the end of your original map).

What about something like:

itera = m_mapFinalSortVirusData.end();
itera--;
int nCount= itera->first;
CString strvirname = itera->second;
