Hi,

I am using CRichCtrl for displaying text. I have data in columns.
It is coming is correct format. But If line is having a space in starting then It is not displaying the space because of that my formatting is not coming correct.

If data is

10
 9

it is displaying like
10
9

I can no not use Right aligned becuase my other data will get spoiled.
Please suggest.

I assume you actually mean CRichEditCtrl[^]. In order to line up columns you need to use a fixed width font for that field; see the difference as follows (I use the character i in order to demonstrate the width clearly:

10
i9 - variable width

10
i9 - fixed width

You are right its CRichEditCtrl.
Please suggest me which fixed width font I need to use?

Use whichever one offers the clearest type for you and your users.

Wouldn't a grid or list control be better suited for this?

Thanks for reply becouse for lots of trial i get first reply

now my problem is strait forward
i have two application on depend on another
like
i have mfc application for user selection to generate some data to create .cpp file
now this .cpp file used by WIN32 API project to create a Win32 api exe my second project.

my concern only with win32 exe not with MFC exe so

i want to execute win32 exe after mfc application selection complete

Yes but again, what is your problem? You want to do something after some other event, so add some code to your MFC app to start the second app at the appropriate time.

So have you tried using ShellExecute() or CreateProcess()?

Your question is not clear, those two should work fine side by side and interchangeably. MFC is based around the Win32 API, although you can't call MFC directly in a pure Win32 application without including the necessary libraries and linking the associated compiled MFC libraries.

Hi,
I would like to convert this function from C to C++.I attempted the conversion below, but not sure if I got it correctly.
- note: debugger would crash at msg[i] = nul in the c-like code.
-I also have the feeling this function can be written in 2 lines with strings!

Thanks

C++

#define NUL 0
char z_buf[4095]

void replace_html_delimiters(char *msg)
{
for(i=0; ; i++)
   {
	   if(msg[i]== NUL)
		   break;
	   if(msg[i]=='<')
	   {
		   msg[i] = NUL;
		   strcpy(z_buf,msg);
		   strcat(z_buf,"<");
		   strcat(z_buf,msg+i+1);//confusing me
		   strcpy(msg,z_buf);
	   }
   }
}

//C++

XML

<pre lang="c++">
#define NUL 0
char z_buf[4095]

void replace_html_delimiters(string msg)
{
for(i=0; ; i++)  //Why no upper limit here?
   {
       if(msg[i]== NUL)
           break;
       if(msg[i]=='<')
       {
           msg[i] = NUL;
           strcpy(z_buf,msg.c_str());
           z_buf += "<";
           strcat(z_buf,msg.rightOf[i]);
           strcpy(msg,z_buf);
       }
   }
}</pre>

You could do it like this:

string replace_html_delimiters(string msg)
{
	for(int i=0;msg[i];i++)
		if(msg[i] == '<')
			msg.replace(i,1,"<",0,4);   // "& l t ;", CodeProject won't display this properly but I'm guessing this is what you want.

	return msg;
}

The msg[i] == NUL has been moved to the for-loop and the replace[^] function is used for replacing '<'-characters with & l t ;.

Note that unlike with a char array, a string will not be modified when passed to a function like this. I solved this by returning the output string, but you could also convert your function to accept a string pointer as argument.

Great, I think this is what I needed. I ma not sure about the for(int i=0;msg[i];i++)
as a terminating condition. Did you mean to put something else instead of msg[i]?

C^hris L^osinger14-Sep-11 9:06

when msg[i] = 0, the loop will stop. ('false' = 0, in C/C++)

Software200714-Sep-11 9:16

14-Sep-11 9:16

for(int i=0;msg[i]=0;i++) crashes.
for(int i=0;msg[i] !=' ';i++) seems to be okay.

msg[i]=0 is an assignment. (sorry, i wasn't speaking C, when i typed it, in my comment above)

'msg[i]' in a conditional is equivalent to 'msg[i]!=0'

Software200714-Sep-11 9:28

14-Sep-11 9:28

Sorry, but I am a bit confused.
I am on C++ compiler now, and both of the following crash.
for(int i=0;msg[i]=0;i++) //I understand this is no good, it's an assignment
for(int i=0;msg[i]!=0;i++)//but shouldn't this work?

yes, it should.
what's the value of i when it crashes ? and how long is the string?

I send in a string "<title>Test";
19 characters long.

The loop crashes at index 25

for(int i=0;msg[i];i++)
{
if(msg[i] == '<')
msg.replace(i,1,"<",0,4);
}

The string actually becomes 25 characters after replacing '<' with //"<", so the very last iteration, it increments i to 25, it tries to check the condition msg[25], I believe it crashes since the string is only 24 chars long ?

How are you calling replace_html_delimiters()?

Software2007 wrote:

Crashing aside, why are you replacing < with the string equivalent? Wouldn't a simple msg[i] = '<'; suffice?

I am trying to replace the C code in my original post. Unfortuantely, CodeProject keeps replacing my "& l t ;" with "<". I had to put spaces just now to display it, but in the code, there is no space between the 4 letters.

C^hris L^osinger14-Sep-11 10:16

14-Sep-11 10:16

this works for me:

XML

#include <string>

void repl(std::string &msg)
{
   for(int i=0;msg[i];i++)
   {
      if(msg[i] == '<')
         msg.replace(i,1,"&lt;",0,4);
   }
}

int _tmain(int argc, _TCHAR* argv[])
{
   std::string f = "<title>blah</title>";

   repl(f);

    return 0;
}
