Hello
Everybody ,as always i give thansk to all of you to resolve my last problems.This time my stuck with following problem.
I have to built a mfc aplication in Visual 6 c++ in which i have a combobox,to whom i have to load elements from a .ini o txt files ,like if user want to add more elements in the combobox by just adding elements from ini o txt the corresponding files.
i was thinking to user getprivateprofilestring() but it is very limited ,then i have to use many of these funcions in my application .
Please tell me how should i built this application
Thanks in advance

write a class to wrap some of the function. And by doing this rethink the design of your code.

But i should be need something flexible , i am thinking about the template of Array ,something like
that ,but i dont have any idea to use template and how to load them .

Do you know about different sections in an ini file?
You should have described your problem with some code.
I am still convinced that you have a desing issue proble

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,

[T_FREC]
DES1= 100.001,
DES2= 100.002,
[T_EMPL]
NAME1= JOHN,
NAME2 = SILI,
for(...)
{
sprintf( s, "DES%1", i );
...
}
i guessed it

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?

Sorry for a late response
If i user the GetPrivateProfileString() ,but it doesnot give a flexibility ,as you say ,just i need that user can add ID1 ,ID2.... .what should i do for flexiblilty
Take care

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.

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

I took it that he was reading from the INI file, not writing to it.

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?

So MSDN is wrong? Write a remark to them...
