As in the subject line I want to make an EditBox that divides the input in multiple lines (like MSWord does when reaches the end of line).

Is it possible in VC++6?

Yes. Use the ES_MULTILINE style.

A question about the sleep() function

While the sleep() function is executed, can another method in the same program run?

If not, how can I make 1 method run while the other is delayed?

You can use Timer for the function where you have used sleep() function.
It is more easier than using thread.

Append String to character buffer

Hi all,

I'm struggling to add a string to a certain portion of a buffer. The buffer size is 300. I'm using a ini file where I keep the coordinates (From Position - To Position). So now I want to take the string and using the coordinates put data into certain positions into the buffer. For example:
[DATA]
NAME=(1 13)
AGE=(14 17)

Lets say the string has a value of: "Hallo There Walter 20"

So I perform a substring on the string using a dirrerent structure, where I get hold of the NAME and the AGE (this step is working thus is not relevent - this is only a test string)

Now I want to use the above ini format for NAME and AGE to put it into the buffer. So from position 1 to 13 I want to put 'Walter ' (filling with spaces) and then from position 14 to 17 I want to put '20 '.

An I making sense ??

Thanks in advance

Basically, yes.

You want a string class (std::string or CString) and its substr() or Mid() functions.

Failure is not an option - it's built right in.

What about

void copyat(char * strBuffer, char * strSource, int iStart, int iEnd)
{
  int iLen = strlen(strSource)
  for ( i=0; i< iEnd - iStart + 1; i++)
  {
      strBuffer[iStart+i] = i < iLen ? strSource[i] : ' ';
  }
}

?

of course, same preconditions must be satisfied (for instance, strlen(strBuffer)>iEnd, ...).

Thanks CPallini. But when I try the function, during the for loop, strBuffer value stays empty ... why is that ?

Thanks again Smile | :)

maybe strBuffer is not properly initialised (for instance, if strBuufer[0]='\0' you see an empty string). The code snippet simply writes the requested, blank-padded, string at choosen position. Anyway, I will perform a little test.

char buff[300];<br />
sprintf(buff,_T("%-16s %d"),"Walter",20);<br />
printf(buff);<br />

Will output:

"Name 20"

Looks like the forum removes spaces too!

It will output:

Are you referring to the HTML non breaking space? '&nbsp'?

If so, I considered that on the second post, but took the lazy route since I did not feel like pasting 20 of them.

It's not difficult: Have a look at GetDlgItem, either the MFC flavour or the WINAPI one, depending upon your tastes.

Well the "easy" way is to hire an experienced skilled software developer. You know... someone that has spent years of their life studying the vast expanse of the software development world and therefore knows and understands the fundamental, complex and detailed aspects of it.
