The file is not the same for all the user of the application, it is different for each user. So i cann't add it to resource.

In that case why use XML at all? Just create a binary file that encodes the information you require, and add code to your application or installation program to read and process the contents.

I imagine the changed requirement is to prevent your customers from seeing the details of the configuration file?
If so, I'd suggest simply obfuscating the XML by running it through some encoder/decoder. This way, you still have the benefits of an extensible and flexible format, at the cost of an extra step when reading/writing the file.
Of course, how complicated this would be depends on what XML parser you are using, as I don't think there's one in MFC.
If your parser can parse from and export to a string - and if the string isn't excessively large - you can simply read your encoded binary data from file, decode it to a string, and parse that. Similarly, when saving the config, you'd export to a string, encode that, and save it to file. If your parser needs to work with files, you can use the %TEMP% area for the conversion.
There are plenty of encoders you could use, from base64 to libzip to various crypto algorithms, so just pick one that is quick, and simple to integrate.

That doesn't really sound like a 'configuration' file to me.
What are your real requirements?
Why exactly does it need to be binary?

Hi.
I want to develop in an embedded system. It's OS dos not support any graphic API and functions except SetPixel for developer.
I need to use some standard font for text drawing.
If you have any idea to do that, please share with me.
Thanks very much.

You'll have to write your own routines for drawing text.
The way this was done back in the day was to create a fixed-size font (usually consisting of 8x8 monochrome pixels, so each character would take 8 bytes to describe), and a simple look-up algorithm (in this case something like "base address of font + character code * 8).
If you have to work pixel by pixel, I'd start with writing a routine to draw a row of 8 pixels, and use that to draw the whole character.
There are some classic old fonts to look at here: http://damieng.com/blog/2011/02/20/typography-in-8-bits-system-fonts[^]
You'd have to convert them to your own format, but that's reasonably trivial. If you take the first (PET), resize it so that there's one real pixel per used pixel, and save the image as a monochrome (2-bit) bitmap, you can read it out from there.

I want to insert into a listview an item with an image :
BOOL CTestListImageView::PreCreateWindow(CREATESTRUCT& cs)
{
cs.style |= LVS_REPORT;
return CListView::PreCreateWindow(cs);
}
and
void CTestListImageView::OnInitialUpdate()
{
CListView::OnInitialUpdate();
CListCtrl& ListCtrl = GetListCtrl();
m_TraceImageList.Create(IDB_BITMAP_TRACEIL,16,1,ILC_MASK);
ListCtrl.SetImageList(&m_TraceImageList,TVSIL_NORMAL);
ListCtrl.InsertColumn(0, _T("Machine model"),LVCFMT_LEFT, 200);
ListCtrl.InsertColumn(1, _T("Description"), LVCFMT_LEFT, 250);
int nIndex = ListCtrl.InsertItem(0, _T("Test"),2);
ListCtrl.SetItemText(0,1, _T("aaaaaaaaaa"));
}
CTestListImageView class is derived from CLIstView, the m_TraceImageList data member is type of CImageList class, and have 10 images ...
still, the listview have not any image ( icon ) ... why ?
Why ? What I have do wrong ?
One mention : I prefer to insert an item with image with follow prototype :
int InsertItem( int nItem, LPCTSTR lpszItem, int nImage );
not with
int InsertItem( const LVITEM* pItem );
Thank you.

Have you tried different values for the cx and nFlags parameters?

I have try in follow ways :

m_TraceImageList.Create(IDB_BITMAP_TRACEIL,16,1,ILC_MASK);
m_TraceImageList.Create(IDB_BITMAP_TRACEIL,16,1,ILC_COLOR | ILC_MASK);

m_TraceImageList.Create(IDB_BITMAP_TRACEIL,16,1,ILC_COLOR8 | ILC_MASK);
but un vain ...

these iages are into an bitmap resource, IDB_BITMAP_TRACEIL

Have you tried using LVSIL_SMALL when setting the image list?
If you vote me down, my score will only get lower
|
|
|
|
|
Also TVSIL_NORMAL is a tree control image list style flag, you would need LVSIL_NORMAL. the values may be different.
If you vote me down, my score will only get lower

Now it goes with TVSIL_SMALL .. thank you all.

Hi
I want to show a modeless dialog (in a SDI project) that I can use it when any other modal dialog of project is open.
I set the always on top style so I can see it when any other project's modal dialog is open, but I can't use it. I must close the modal dialog first and after that I can use my first dialog(modeless).
I set the parent window to CMainFrame and then NULL, but both ways did not work fine.
Also I tested some other styles, but found nothing.
Is there any way to do this?

<blockquote class="FQ"><div class="FQA">Hadi Dayvary wrote:</div>...but I can't use it.</blockquote>
Why? What's the problem? Does it show but can't be interacted with? Does it show but stays in the background? Does it fail to show? How, and when, are you displaying it?
<blockquote class="FQ"><div class="FQA">Hadi Dayvary wrote:</div>I must close the modal dialog first and after that I can use my first dialog(modeless).<BR></blockquote>
This sounds like normal behavior of a modal dialog.

it's shown but can't be interacted with.
I have created it in CMainFrame::OnCreate()
like this :
m_dlgCalling.Create(IDD_CALLING, NULL);
m_dlgCalling.ShowWindow(SW_SHOW);
or this:
m_dlgCalling.Create(IDD_CALLING, this);
m_dlgCalling.ShowWindow(SW_SHOW);

So you are creating and showing the modeless dialog during the creation of the main frame, correct? Where does the modal dialog play into this?

modal dialogs come when user selects an item from the menu.

And by definition, modal dialogs must be dismissed before you can interact with any windows behind them.

I know, but I must do this for our project,
There must be a way to do something like this.

You can always create the modeless dialog via it's own UI thread. The issue is the modal dialog is preventing pumping of your messages.
onwards and upwards...

thanks.
Do you mean that I must create create a thread and then craeting the modeless dialog from that?

Hi There ,
I am stuck with this problem since weeks. Apparently I am new to Visual Studio. I have a client dll which exposes some APIs . I am supposed to create a C++ Unit Test project in Visual Studio 2005 and test the methods in the dll. Unfortunately I am not able to invoke the methods , I often get linking errors such as
"error lnk2031: unable to generate p/invoke for"
The .h file has some function exports .I am pasting part of the .h file here
//.h file starts
#ifdef ITMENTITLEMENTWRAPPER_EXPORTS
#define ITMENTITLEMENTWRAPPER_API __declspec(dllexport)
#else
#define ITMENTITLEMENTWRAPPER_API __declspec(dllimport)
#endif
// This class is exported from the itmEntitlementWrapper.dll
class ITMENTITLEMENTWRAPPER_API CitmEntitlementWrapper {
public:
CitmEntitlementWrapper(void);
// TODO: add your methods here.
};
extern ITMENTITLEMENTWRAPPER_API int nitmEntitlementWrapper;
ITMENTITLEMENTWRAPPER_API EINSTALLTYPE fnGetInstallType(const wchar_t * InstallType);
ITMENTITLEMENTWRAPPER_API int vm_wstrcmp(const wchar_t* s1, const wchar_t* s2);
extern "C"
{
/**
* fnitmEntitlementWrapper_ENTITLE_INST_FIRST - The purpose of this method is to load the caEntitlement.dll*/
ITMENTITLEMENTWRAPPER_API BOOL fnitmEntitlementWrapper_ENTITLE_INST_FIRST(const wchar_t *eProductID = L"eProductNone",
const wchar_t *ePackageID = L"ePackageNone", HWND hWndParent = NULL);
//.h file ends
How am I supposed to call these methods in UnitTest.cpp. I am adding a dll reference to the Testing project and also tried to use DLLimport . Can anyone please help.
Thanks
Diya

I first saw this technique in the stl where collections return
std::pair<iterator, bool> from their insert method. The bool indicating if the item was inserted or already existed.
Personally I dislike this, I find the names first and second which identify the pair's elements very misleading and find I'm constantly having to look at doco to see what something is. The worst case I've seen was along the lines of
pair<bool, pair<bool, bool> . How could anyone be expected to remember what result.second.first is?
I prefer to pass in a reference to a variable
eg
iterator map::insert(iterator position, const value_type& x, bool& wasAdded)
This has the disadvantage that the caller has to allocate a bool and pass it in even if they're not interested in the result (this can be overcome by using a pointer with default value of NULL but that's also ugly)
I blame python and its tuples for this outrage. What do others think?
