why do people still use printf() is cout is available?
1. Some people are still writing in C, not C++
2. It's a legacy program that still uses the C runtime library, so why make it bigger by using STL as well?
3. Some people are too lazy to learn something new

wel, i knew people were still using C, heck, i still use C. but what about in MFC, why do some people use printf?

I dunno. Heck, even MFC uses printf(). Check out CString::Format() - it uses _vstprintf() I think, from memory.
I generally use printf() because I come from a C background, but I do use cout as well. Depends on my mood

Because there are some limitations to cout/cin that printf handles better. You can look up all the hacks to cout/cin to see what I mean. However, printf does have serious limitations. Also, stream usually add around 80k to an application.
If you just want to format a number, use ltoa. It is magnitude times faster than streams (and yes, I have seen many people use streams for simple conversions).
But then again, ltoa is so old school and just for lazy people.

I'm going to patent thought. I have yet to see any prior art.

Yeah I know. I write my own... from scratch... every time

One of the benefits of using cout is that it can display many types without the programmer having to specify any formatting, whereas with printf() you'd have to specifiy all of those % thingies. That said, when I am creating a console application, I use printf() nearly 100% of the time, unless I am showing someone how to do something C++ specific (e.g., if your object provides >> and << operators, it can fit right in with cout and cin).

Hi there
I have a big project written in MFC 4.2 with Visual Studio 6. Since I bought Visual Studio .net, I immediately wanted to convert it to MFC 5 but there is too many bugs 
If someone have a tool or documentation about changes between MFC 4.2 and MFC 5, please send it to me
Thank you !

Hi,
I'm trying to write an MFC application in VS.NET2003,
I've changed nothing in the wizzard wich will be displayed after choosing project name and type etc.
After pressing "finish" in the wizzard I pressed CTRL+SHIFT+B ("build"), expecting everything would be fine. IT WASN'T:

Not sure this gonna help.
Try to include in your header.
#include <atlstr.h> // CString support.
#include <atltypes.h> // CPoint, CRect, CSize support.
there are many good articles in codeproject which demonstrate the porting.

Ok thanks,
But, when I now complete the wizzard, a messagebox is shown with error rc2104: undefined keyword or name: ds_shellfont
what is this?
|
|
|
|
|
I am not sure what is ds_shellfont. But my suggestion is, you should trim your app to smaller chunk to see what is missing.
Although Ms provide IjW to convert your VC6 to VC7 but it is not a magic.
From what I had learned in codeproject. VC7 do conversion by supplying ATL to replace your old MFC classes. The two header I suggested are ATL header.
|
|
|
|
|
I can't trim the application anymore,
It's already a standard app generated by a wizzard, so it has only minimal functionality

Hi,
is it possible to remove all DOS line endings (from a file opened in VC editor)? Possibly a plugin in VC would be very nice. I want to convert all DOS line ending into Unix-style line endings at a press of a button.
Thanks for help, Mark

|

Personally, I just use EditPlus or UltraEdit. It doesn't take too long to load them again, and does the job nicely.
But I haven't found a plugin yet that does this

What VC IDE are you using, .NET or 6.0? Cause if it is .NET you could just write a macro to do that rather easily; it's just VB.NET  Or if need be, I could attempt a hack at it...
-Nathan
---------------------------
Hmmm... what's a signature?

I'm using VC6.
If there is no such plugin, possibly I have to write one. It happens too often that I need a dos2unix conversion. Is a IDE plugin possible, are there any articles or tutorials?
Thanks again, Mark

Hi,
I want to use the MFC Array Classes to store an int and a float (in 2 seperate classes) but when I look at the standard ones available they are :-
CByteArray
CWordArray
CDWordArray
CUintArray
CStringArray
CPtrArray
CObArray
Which 2 should I choose for int and float?
They seem like an odd set or am I missing they point?
If you can shed any light on this I would be very gratefull,
Cheers
Ali

Use the CArray template class: CArray<float,float> myArray;

Which 2 should I choose for int and float?
Best choice would be obviously
std::vector< int >;
and
std::vector< float >;
SCNR to plug the standard. 
My opinions may have changed, but not the fact that I am right.

Hi,
I've got an application that loads driver DLL's. Those driver DLL's have some setup options. Now I want those driver DLL's to display a property page in the application setup dialog that already has a property sheet with pages.
The solution is simple, just let the DLL create a MFC CPropertyPage. But I don't want that, I don't want that the Driver DLL's must be MFC dll's (and compiled with a matching VC++ version/libraries).
I tried creating a CPropertyPage in the DLL and then returning the propertypage HWND to the application. The application then attaches the HWND to a CPropertySheet. That runs into al kind of problems.
Lookign trough the MSDN library a found al sorts of ATL and COM anwsers, but there must be something simpler.
Note: Of course the driver DLL must handle the window messages for its property page.
Thanks,

Why not expose a function from the dll to add the property page(s), given a propsheet handle. Then, in your CPropertySheet::OnInitDialog(), simply call the function prior to calling the base. This may work (have never done it). See PropSheet_AddPage() macro for more info.
onwards and upwards...
