Nearly all of Boost is in headers and it does not add lots of code to your app. The fact that it is large is irrelevant IMO. MFC and STL are also large.
I would definitely recommend using STL and Boost wherever possible instead of the MFC Containers (which I used to use heavilly).
Boost.MultiIndex will do what you want and it looks quite elegant. Of course you can use two CMap's or two STL map's but why would you want to.
Make the move to STL and Boost and you'll never regret it.;)

Well, I've only comparatively recently moved from dial-up to broadband. With dial-up it just wasn't worth it. Now I've got broadband it's more psychological.

Recently I've been more focused on .NET,so I've not had much incentive to look into Boost. When I do get to do C++ it's invariably maintenance work on code that's barely heard of STL, yet alone Boost! (For that nmatter it's often barely heard of MFC's data structures!) I just don't think it would go down too well if I downloaded Boost just to do maintenance work.
However, for new work or new extensions to MFC apps. I tend to go for STL containers nowadays. Still, I do intend to give Boost a try at some point.

You probably can insert only the relevant classes into your project.
Boost is all source code.
I am doing so with the smart-pointer classes from boost.
You will want to stay well clear of the MFC-containers, as the STL containers are better in all respects, and are well documented and portable.

If you're working on an MFC app. it's generally going to be non-portable anyway, so why is it important to use portable STL? I agree that the STL containers are better and I use them for that reason, not because they're portable.

If you don't expect the number of keys to be very large, you could just write a simple function to do the latter (i.e. return the collection of keys that map to the value).

Thank you very much. I also found that article, after I posted my request. I already programmed my own CMap extension class, because I use MFC in my project (and therefore don't use STL, because I don't want to mix them). I will write an article about my extension class for codeproject when I have some free time.
Regards
Konrad

Hi all,
I am about to become a crazy man because of the following:
I want to use a structure and some functions in winuser.h file, I #include it and link user32.lib with my project, but the compiler always tells me that they are undefined, I tried this on many projects and always the same:
I write :
INPUT i;
and the compiler writes:
error C2065: 'INPUT' : undeclared identifier
Please try it.
I feel like I have not ever done anykind of programming.
Regards,
Mohammad

Hi Mike,
Thanx for replying my message, but I have another question:
the FAQ question you refered includes a link to micrososft windows sdk updates, but when I got into the page I found that these updates are for Windows Server 2003, should I install these on Windows 2000/XP/98?
Do they work well for these platforms?
If no, Where Can I find other SDK updates for other versions of Windows?
Regards,
Mohammad

Hi,
Are you sure that th compiler is familiar with these files?
Go to Tools->Options,choose the "directories" tab,and search in the list box those directories(Full path name).
If it's not in the list box,you should add this(add the directory of winuser.h to the "include files listbox" and the directory of the user32.lib to the "library files list box").
this sould solve your problem.
Good luck,
Eli

Questions:
how to delete some installed files (i.e. COMs) which are used by Windows system by inno uninstall (in section or script)?
those files were installed by inno setup.
normal uninstall does not work for these files because they are used by system and can not be deleted - even can not be deleted manaully.
thx

Hello There!
Let Consider the m_strEditBox of type CString which is the variable associated with the EditBox from which you want to get text input by User.
now! For Getting Text in to your Variable i.e. m_strEditBox
Call UpdateData(...); with TRUE as Argument
this->UpdateData(TRUE);
this will fill your m_strEditBox with the data entered by user
.................
Now do anything with the m_streditBox variable i.e. broke in token etc etc.
..................
now if you want to update the data back to Edit Box
just again Call UpdateData(...); with FALSE as argument
i.e. UpdateData(FALSE);

Thanks.
how do I display my output in some other edit box now .
|
|
|
|
|
Now let the m_strEditBox1 of type CString is associated with some other edit box where you want to put data.
//now give value to m_strEditBox1
m_strEditBox1="Codeproject is great";
//Update the data back to edit box call UpdateData
this->UpdateData(FALSE);

CEdit m_MyEditControl;
CString m_csEditControlText;
// fill in edit field immediately, bypassing dialog's UpdateData call...
m_MyEditControl.SetWindowText(m_csEditControlText);

check msdn for GetWindowText().

Just curious to know, Where you got the information that the GetWindowText() function will return the edit text ?

void CWnd::GetWindowTest( CString& s );
well duh ( sorry, it's 3:00 am, and I'm not asleep ), you pass a reference to a CString to GetWindowText...
CString myString;
MyEditBox.GetWindowText( myString );

As Maximilien said, you give the GetWindowText() a String, and it will fill it for you.
As for getting the right variable to call GetWindowText() on, you can use the ClassWizard to make a so called Control Variable for you. Thats a variable of the Type of your control (probably CEdit) and you can use it without resorting to the complicated and confused UpdateWindow()-stuff.
You just need to set one hook in the Class Wizard.

I have the following code adding to a CListCtl on a dialog box named m_cList, but for some reason the first element I add doesn't show up:
<br />
LRESULT CRTFParseTest1Dlg::OnCreateListGroup(WPARAM wParam, LPARAM lParam)<br />
{<br />
CStringArray sa,<br />
sa1;<br />
CString sFormat;<br />
<br />
for(int a(0); a < 3; a++) {<br />
sFormat.Format("Column %d", a);<br />
sa.Add(sFormat);<br />
}<br />
InsertColumns(sa);<br />
sa.RemoveAll();<br />
<br />
sa.Add("Item");<br />
for(int b(0); b < 5; b++) {<br />
sFormat.Format("Group %d", b);<br />
AddListGroup(b, sFormat);<br />
<br />
for(int b_0(0); b_0 < 2; b_0++) {<br />
sa[0].Format("%d:%d", b,b_0);<br />
AddItemToGroup(b_0, sa, b);<br />
}<br />
}<br />
<br />
return 0;<br />
}<br />
<br />
<br />

<br />

if(m_cList.EnableGroupView(TRUE) == -1 || !m_cList.IsGroupViewEnabled()) {<br />
TRACE("==>CParseTest1Dlg::AddListGroup { Could not enable list grouping }\n");<br />
return -1;<br />
}<br />
}<br />
<br />
LVGROUP lvg;<br />

<br />
lvg.cbSize = sizeof(LVGROUP);<br />

<br />
return m_cList.InsertGroup(-1, &lvg);<br />
}<br />
<br />

{<br />

<br />

<br />

}<br />
}<br />
return iRes;<br />
}<br />
<br />
bool CRTFParseTest1Dlg::InsertColumns(CStringArray &sColumnTitles)<br />
{<br />
int iRes(0);<br />
for(int i(0); i < sColumnTitles.GetSize() && iRes!=-1; i++) {<br />
iRes = m_cList.InsertColumn(i, sColumnTitles[i], LVCFMT_LEFT, 100);<br />
}<br />
return (iRes != -1);<br />
}<br />
Any idea how to make it work?

your code displays 10 elements and is working. starting from 0.0 to 4.1 . Which is the exact string you feel is missing as per the code.
