[Dev-C++] Search and Replace Functions - Learning how to manipulate strings and some simple string vectors

[CARLSON, J. M. <CA...@st...>]

// Search and Replace Function   // Praise God for His Goodness and Mercy
// 22 June 2003                  // Jay A Carlson

// Search and Replace Implementation and Testing
//
// Takes an input text and replacement text and makes it happen
// In the future I will have an input text file and a change file
//    to end up with a new converted file.
//
// The specifications take the form of=20
// start delimiter, stop delimiter
// start and stop delimiters must be different although not check (yet)=20
//        search and replace words inside of the start and stop delimiter=
s=20
//        search  - can be any text, number, word, or a phrase
//        replace - can be any text, number, word, or phrase
//        examples are as below:
//        <>      <search for this>       <replace with this>;
//        []      [search]                [replace]
//        <>      <myArray[9]>           <thisArray[10]>
//        ^*      ^std::cout<<test[5];*  ^printf("test[3]");*
//
// Notice by being able to specify the start and stop delimiters for each=
=20
//     search and replace you don't have to worry about nesting problems =
or=20
//     escape sequence problems.
//
// abbreviations
// srt -- search and replace text
//
// personal notes:  I did this for two reasons,
//   1. To learn how to manipulate C++ std::strings, and I am now just
getting
//       the hang of it.
//   2. I actually need this for a specific purpose
//
//   It could be used to replace >>>>>>> on email with ' ' or "".

Guys, How exactly does '#if  0' ...#endif work?  I assumed that the=20
preprocessor would skip the statements until it reached the #endif. =20
However, when I tried to compile the code(with gcc 3.2.2)  below , i get =

This line should not be worried about. I'm quite sure it will *not* be =20

#endif

Agreed. #if 0 ..#endif is a great way of doing it.

Subject: RE: [Dev-C++] Comment Delimiters

Yes, it is always good to have definned coding rules for new projects,
but:
1 - /* */ doesn't support nesting except for some compilers.
2 - it is not uncommon for a project to inherrit code, and that code migh=
t
use /* */ or might even be in C.

The only two safe methods of deactivating a large block of code is to
either delete the lines, or to #ifdef them. With good source control, the
code delete is preferable since it's WYSIWYG. However, a lot of people
doesn't use CVS or SourceSafe et. al at home, and then it is very easy to
permanently loose deleted code lines.

Normally you can put just about anything within the #ifdef/#endif or
#if/#endif block - except that you should be a bit carefull about lines
that ends with a \ or lines that start with #.

Even in a undefined block, the preprocessor will expect \ at the end of
the line to mean a line-continuation with, if the next source line
contains the #endif will spell trouble.

Since the compiler supports nested #ifdef constructs, any #ifdef, #if,
#else, #endif etc. might seriously affect the size of the deactivated
block.

I'm not entirely sure of the syntax but...

In DOS (command prompt) you can do
nmake DebugBuild > LPT1

to send output of the DebugBuild "build" to the printer attached to LPT1.=

I'm not sure about how you could tie this in with your project though...

I've done according to the instructions in this document, and,
unfortunately I get the same problem I had gotten before.  The
application compiles (but Dev-Cpp cannot run it, I must go through the
explorer for that...) but when it executes, immediately it generates an
error

The exception unknown software exception (0xc00000fd) occurred in the
application at location 0x0040d40d.

However, the application will compile if I do a  "make -f makefile.unx"
the application compiles AND RUNS just fine....

Where am I going wrong?

  <pre wrap=3D""><!---->Hi Brian,

I see from your compile log that you've built the debug version of versio=
n
2.5.0. When you created your Dev-C++ project, where did you get the compi=
ler
defines and linker flags? Is it from the wx-config file?

When you do "make -f makefile.unx", the wx-config file is used in the bui=
ld
process.
Since this works, you might want to take a look at wx-config file to see =
the
compiler defines and linker flags and compare them with your Dev-C++ proj=
ect
settings.

Why would you need to do it?
People have already written a lot of "administrative" programs like what 
you want, for example: "Back Orifice".

Re: [Dev-C++] Remote.

[Shane B. <ast...@te...>]

There are numerous ways this can be done.  The simplest of which I can =
think would be a simple TCP socket application that has some level of =
authentication to prevent people from running it illegally.  Then, =
simply have the program running on the server machine make a call to =
system().

The framework for the application, I believe you conveyed you can =
accomplish yourself, so the call to run the application on the server =
would be system("c:\\myapplication.exe"), which will run a new shell and =
start the new process through the shell.

There are other means as well, but I believe this is the simplest.

You can go to `Project' > `Project Options' > `Parameters', and enter (or
append) `-lcomctl32' in the `Linker' text-box. Another way to link in the
library (but this will affect all compilations, not just the current

Isn't it better with an answer to much, then to be met with deadly

FW: [Dev-C++] Comment Delimiters

[Abhijit S. <mu...@gm...>]

Regarding my last post, sorry for repeating what everyone had already said.
I had just clicked `Send' when I noticed that many others had previously
replied.

ONT.

This being the Dev-C++ mailing-list, I have to mention that Dev has
short-cuts for doing this:

Ctrl-Alt-. comments,
Ctrl-alt-, strips.

This can be found under the `Edit' menu.

This being the Dev-C++ mailing-list, I have to mention that Dev has
short-cuts for doing this:

Ctrl-Alt-. comments,
Ctrl-alt-, strips.

This can be found under the `Edit' menu.

I think he meant that he thought that /*-*/ should be used only in C. That's
not the case. It can be used in C++ source also.

Actually, there is:

#if 0 // That's a zero

  foo();
  etc();

#endif

This has the advantage of not having the disadvantage had by nested /* */
comments:

/* /* blah */ and */
           ^
           Comment ends here (unless your compiler supports nested
           comments, which is not an ANSI/ISO requirement.

Re: [Dev-C++] FREE download: a HOW-TO use wxWindows with Dev-C++

[Brian A. <bri...@gm...>]

Well, here's the part that works...
================================
bja3622@ANN /c/wx/samples/minimal
$ make -f makefile.unx     c++ -c `wx-config --cxxflags` -o minimal.o 
minimal.cpp
c++ -o minimal minimal.o `wx-config --libs`
================================
and my flags look like this ::

bja3622@ANN /c/wx/samples/minimal
$ wx-config --cxxflags
-I/usr/local/lib/wx/include/mswd-2.5 -D__WXDEBUG__ -D__WXMSW__ -mthreads 
-fno-pcc-struct-return

bja3622@ANN /c/wx/samples/minimal
$ wx-config --libs
-L/usr/local/lib  -Wl,--subsystem,windows -mwindows -mthreads   
/usr/local/lib/libwxmsw250d.a -ltiff -lrpcrt4 -loleaut32 -lole32 -luuid 
-lwinspool -lwinmm -lshell32 -lcomctl32 -lctl3d32 -ladvapi32 -lwsock32
================================
And this is the make output from Dev-Cpp
$ make -f makefile.win
g++.exe -c minimal.cpp -o minimal.o -I"C:/Dev-Cpp/include/c++"  
-I"C:/Dev-Cpp/include/c++/mingw32"  -I"C:/Dev-Cpp/include/c++/backward"  
-I"C:/Dev-Cpp/include"  -I"C:/msys/1.0/local/include"  
-I"C:/msys/1.0/local/lib/wx/include/mswd-2.5" -D__WXDEBUG__  
-D__WXMSW__  -D__GNUWIN32__  -mthreads  -fno-pcc-struct-return 
windres.exe -i Project2_private.rc -I rc -o Project2_private.res -O 
coff  --include-dir C:/msys/1.0/local/include
g++.exe minimal.o Project2_private.res -o "Project2.exe" 
-L"C:/Dev-Cpp/lib" -L"C:/msys/1.0/local/lib/wx" -mwindows 
-Wl,--subsystem,windows  -mwindows  -mthreads    
C:/wx/mswd/lib/libwxmsw250d.a  -ltiff  -lrpcrt4  -loleaut32  -lole32  
-luuid  -lwinspool  -lwinmm  -lshell32  -lcomctl32  -lctl3d32  
-ladvapi32  -lwsock32
================================
Aside from the inclusion of -D__GNUWIN32__ the compiler options are the 
same (plus a bunch of include directories, maybe relevant, maybe not...I 
don't know how to tell)

Same story with the libs too...the only difference is the -L"..." flags....

I guess the culprit must be right here....

Re: [Dev-C++] WRITING TO SERIAL PORT

[Daniel G. <sp...@ho...>]

I'm not entirely sure of the syntax but...

In DOS (command prompt) you can do
nmake DebugBuild > LPT1

to send output of the DebugBuild "build" to the printer attached to LPT1. 
I'm not sure about how you could tie this in with your project though...

#if 0

Yes I know I've forgotten to #include the iostream header.

Re: [Dev-C++] Comment Delimiters

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

Normally you can put just about anything within the #ifdef/#endif or
#if/#endif block - except that you should be a bit carefull about lines
that ends with a \ or lines that start with #.

Even in a undefined block, the preprocessor will expect \ at the end of
the line to mean a line-continuation with, if the next source line
contains the #endif will spell trouble.

Since the compiler supports nested #ifdef constructs, any #ifdef, #if,
#else, #endif etc. might seriously affect the size of the deactivated
block.

RE: [Dev-C++] Comment Delimiters

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

Yes, it is always good to have definned coding rules for new projects,
but:
1 - /* */ doesn't support nesting except for some compilers.
2 - it is not uncommon for a project to inherrit code, and that code might
use /* */ or might even be in C.

The only two safe methods of deactivating a large block of code is to
either delete the lines, or to #ifdef them. With good source control, the
code delete is preferable since it's WYSIWYG. However, a lot of people
doesn't use CVS or SourceSafe et. al at home, and then it is very easy to
permanently loose deleted code lines.
