Sorry CPallini,
I have not made myself fully understood. My question is (after reorganization),
1. for template function, we can choose to use either implicit mode to let compiler deduce or explicit mode to assign type;
2. for template class, we have to use explicit mode to assign type?
regards,
George

I suppose that you were asking about something like this (in which case your example is very badly chosen because you specify explicitely the type):
template <class T>
void myTemplateFunc(T arg)
{
}
And to use it, you do something like this:
int myValue = 42;
myTemplateFunc(myValue);
But, in fact even in that case there is no matching involved. The compiler will simply 'generate'a new function and replace T by an integer. Now if you call that function and supply a float, then the compiler will generate a second function and replace T by a float. You have to look at templates as code that will be generated by the compiler once you use the template (be it a class or a function). And if you call your function with two different types, then two different functions will be generated.
The only case where a matching is done, is when you use template specialization (if I provide a version of my function specifically for float for example). In that case, the compiler will try to find the best match. But in general, the compiler is quite intelligent to solve the problem on its own.

Thanks Cédric,
You understand my question well. My question is,
1. for template function, we can choose to use either implicit mode to let compiler deduce or explicit mode to assign type;
2. for template class, we have to use explicit mode to assign type?

Ok, it has logic that if the question was not fully understood, you make the question in another way to try to get the answer you look for. But...

If he understood you well, and you got a good answer (IMHO a perfect answer...). WHY DO YOU COPY-PASTE ANOTHER TIME THE SECOND MESSAGE?
And by the way... Why do you never answer to questions (that the people that answer your messages) make to you?
Honestly, I start thinking this user is a BOT.

Hi All,
This is the first time i am writing to this forum.
So let me staight come to the point .
I am a newbie to MFC , but i understand C,C++.
My urgent need of the hour is that i want to provide a text box on my GUI along with a button , and when this button is clicked the data which is shown/typed in the text box is transferred to any kind of USB device viz a viz USB Pen drive's (or any other USB 2.0 compliant class device).
So has any one done similar kind of work and if yes could you'll provide me some good links wherein i will be able to make a GUI which will allow me to talk to the USB device .
Basically the USB API 's which allows us on a click of a control button to send data to a USB device like a USB Pen drive .
Any help in this regards will be highly appreciated.
Regards
A.G

What does it mean? A TEXT to be transferred to the USB device?

A USB port is not similar to a serial port. You cannot just get a handle to the bus and send data on it. What you need to do, is get a handle to a specific device driver (using CreateFile) and then you'll be able to exchange data with this specific device (using WriteFile and ReadFile). The string you need to supply to CreateFile is something that is specific for the driver. You should check in the documentation that is supplied with the USB device (if it comes with a SDK).

Hi Friends,

While creating the CFileDialog object, you have to pass the OFN_ALLOWMULTISELECT also( 4th parameter )
|

|

OFN_ALLOWMULTISELECT is not my problem.
While opening the CFileDialog all the files should be selected.
How to do that?.
Thanks and Regards.

derive a class from the CFileDialog and overide the OnFolderChange function. Inside that function take the handle of list control and select all items in it.

Programmatically, or using the keyboard/mouse?

Programmatically.
or else
With out the CFileDialog, I have to take all the files in the particular folder in an array. If you know this, let me know.

From MSDN:
"If the user selects more than one file, the lpstrFile buffer returns the path to the current directory followed by the file names of the selected files. The nFileOffset member is the offset, in bytes or characters, to the first file name, and the nFileExtension member is not used. For Explorer-style dialog boxes, the directory and file name strings are NULL separated, with an extra NULL character after the last file name."

Hi all,
Last time I try to write an application to read a RTF format file and get the text on it. But actually it is not much easy. So I've search on the MSDN and found using CRichViewEdit and its members, it can be easy than my first application.
I've searching some articles on code project forum. But not found such things. If you have any link with you please put it here. Or give some clues to me start work on CRichViewEdit.
Thanks.
I appreciate your help all the time...
