While you can use GetPrivateProfileString() to read INI files, it won't do much good when a given section has non-unique keys. Consider the following:
char szBuffer[64];
GetPrivateProfileString("T_FREC", "ID", "", szBuffer, sizeof(szBuffer), "myfile.ini");Would you expect this to read the "ID" key whose value was 1 or 2?

First answer the question here. Until we (and you) know what you are doing, all else is meaningless.

Why?
Have you considered XML?

No in XML ,because in my job ,we have only visual 6 c++.

Nothing prevents you from using XML with Visual Studio 6. For instance you may use MSXML library.

Hereby i give you a sample of my ini.file ,it has section and sub-sections.
In my application i have three comboboxes.Every section will have his respective combobox.
please give a some idea or source code to deal this type of problems
[T_RUTA_ALT]
[T_FREC]
ID= 1,
DES= 100.001,
ID= 2,
DES= 100.002,
[T_EMPL]
ID= 1,
NAME= JOHN,
ID= 2,
NAME = SILI,
please tell me or give me example of source code to upload this files and use it ,may it will be easy for u but i dont have any idea .please help me

This is not a valid ini file. You can't have multiple keys with the same name inside a same section. You are trying to use the wrong tool for the job. As suggested before, you should use something like XML. Here[^] is a simple and lightweight XML library that you could use.

As Cédric said, you should use unique keys. A workaround may be appending the item number to the name, for instance:
[T_FREC]
ID0= 1
DES0= 100.001
ID1= 2
DES1= 100.002

Someone already mentioned that you may need to rethink your design. It would appear that you are using the .ini file as a simple database, and this is not its purpose. You would be better to use a simple text file or XML to store these records.

I have made a Word Add-in. I use the clipboard to put an icon in my Add-in button. The code is:
HBITMAP hFace =(HBITMAP)::LoadImage(g_hInst,
MAKEINTRESOURCE(IDB_OPEN_PDF),IMAGE_BITMAP,0,0,LR_LOADMAP3DCOLORS);
// put bitmap into Clipboard
::OpenClipboard(NULL);
::EmptyClipboard();
::SetClipboardData(CF_BITMAP, (HANDLE)hFace);
::CloseClipboard();
::DeleteObject(hFace);
// set style before setting bitmap
spButton->PutStyle(Office2000::msoButtonIconAndCaption);
spButton->PasteFace();
return S_OK;
OpenClipboard opens the clipboard successfully as it returns 1 every time. The problem is that EmptyClipboard returns 0 every time. It seems that there is a problem with the clipboard. EmptyClipboard gives an error 1418 - Thread does not have a clipboard open. That is strange because I've just opened the clipboard successfully.
Has anyone run into such problem?

From MSDN [^]:
If an application calls OpenClipboard with hwnd set to NULL, EmptyClipboard sets the clipboard owner to NULL; this causes SetClipboardData to fail.
Are you sure is what you want?

Actually this is not quite right . The definition of the hwnd parameter of OpenClipboard is:
Handle to the window to be associated with the open clipboard. If this parameter is NULL, the open clipboard is associated with the current task.
However I tried to pass the hwnd of the program my Add-in is associated with (that is MS Word in my case) but I could not get the Active Window because it is probably not initialized when I ask for it.
The problem is that the program crashes sometimes because of my add-in. The reason is something about using the clipboard. I also noticed that EmptyClipboard clears the clipboard but still returns 0. My icon is usually added but it is unexceptable for me sometimes to crash.
Do you have any idea what can be the reason of the strange behavior of the EmptyClipboard function and the reason that cause the crashes?

This is wrong; you are pointing the clipboard to some data in your app and then destroying that data. You must copy the data to global memory first. Check the documentation on MSDN for the clipboard functions.

There is something strange going on. I found that not only the EmptyClipboard function gives an error 1418(Thread does not have a clipboard open) but also all the functions after that:
SetClipboardData, CloseClipboard, DeleteObject.
It seems like I have forgotten to open the clipboard but I open it successfully as the OpenClipboard(NULL) returns 1. In spite of the fact that all the functions mentioned above give an error, the icon is usually added to my button.
Why can't I open the clipboard as it should be? Could there be another reason for my problem with the Add-in crashes (they appear sometimes) except the clipboard issues?

There may be some extra rules to follow when doing this via an Add-in. I have not used this feature so cannot offer any suggestion.

It seems that I found the problem. It is definitely about the clipboard. So first I figured out how to overfill the clipboard. I just open the MS Word and make a huge file containing about 4-5 thousand pages of witch 30% pictures and 70% text. Then Select All and Copy. When i try to close the MS Word application it asks me if I want to save the clipboard to other applications. I click Yes. Now there is a overfilled clipboard! The MS Word is usually not responding but leave it that way. Don't hurry up shutting it down.
Now when I try to open another MS Word - it crashes because of the add-in. When I debug the add-in it turned out that when the clipboard is overfilled the PasteFace() function throws an unhandled exception. Now the only thing I have to do is to deal with the exception.
