Re: [Dev-C++] Cp vs. copy

[Alfred P. R. <al...@ya...>]

You can also use the DOS xcopy /k to copy attributes.  However, Per is right, and if you use Mingw and/or Msys then you can use cp via DOS.  Read the help on xcopy as there are quite a few options.

copy will append archive flag

copy will not even find system file
copy will not even find hidden file

In short - copy is inferior to cp.

Simple solution: Download a win32-compatible port of the cp command.

Re: [Dev-C++] Win32 Shell API

[Per W. <pw...@ia...>]

Can we expect you to repeat this question until somehow someone new to
this list and takes the time to write something about it? It takes quite
some time to write the answer you like. You can, on the other hand, find
that information without too much google magic.

This is your - at least - third mail about requests for help with shell
copy. And while discussing shell copy - you haven't even mentioned any
special reason for your desperate need for use of this specific function,
or why the answer must come from this list instead of from google.

If the google links contains wrong information, or wrong type of
information, just say so and specify exactly what makes your requirements
completely different from other peoples.

[Dev-C++] Cp vs. copy

Hi, all!
 I need to translate the system command cp -p to work with Windows.=20
 Does anyone know if dos copy translate exactly what cp -p?
 Syntax are as follows:
 LINUX: system("cp -p $oldname $newname");=20
WINDOWS: system("copy $oldname $newname");=20
 I am not sure if copy can copy from one file to the other with EXACTLY the=

same attribute as -p does.
Thanks in advance!

Order does not matter on friend declarations. Most classes I have seen put
them at the bottom because they do not have much to do with what the class
does as a whole.

Re: [Dev-C++] Friend functions

I don't see how that can possibly work.  What you want in this case is
an accessor function like

int GetData() { return data; }

in the public section of your class.

[Dev-C++] Template Bug - *Bug*

[Scott <fre...@ve...>]

Hi,  (Long time listener, first time poster)

I just tried making a template using a "C" Win32.dll=20
There seems to be a bug in the template file created in the template =
directory...
All the files get marked with a CPP instead of just a C syntax.=20

The template definition file incorrectly links
using the following:

CPPName=3Dstartup.c
CPP=3DDLL_startup.c.txt

This creates an empty useless template.
If i manually edit the definition files in the template directory to =
read:

CName=3Dstartup.c
C=3DDLL_startup.c.txt

The template then works fine.=20

There is another minor bug, which also never keeps the "Make C Default =
language" toggle box,
checked to it's default setting.

Thanks!
Cheers,
Scott.

RE: [Dev-C++] MTA COM+ class

[<Mat...@Ve...>]

First you need to Google it to find out whether there is some kind of
re-entrant mode or re-entrance safe functions.
Sometimes you have to do something like #DEFINE _REENTRANT.
If there is a re-entrant mode, that will solve your problem.
Another option would be fork/exec instead of threads.
Lastly you would have mutexes. Mutual exclusion objects.

Re: [Dev-C++] mysql download

The good news is that there is a MySQL dev-pak but it does not have the 
embedded server. If you just want to connect to an external database 
then the Dev-pak should work for you. You can get it throught the "Check 
for updates/packages" menu item in the tools menu of Dev-C++ or just 
search Google for MysSQL dev-pak.

P.S. Switch to Linux and forget Windows programming is definitely not a 
bad thing... :) Sadly the linux version of Dev-C++ is no longer
