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:

"Walter (lots of spaces)20"

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.

No, I was referring to <pre> or <code>.

Accessing an edit box from multiple windows????

I actually tested with <code> in the preview in the second post and it didn't work. However <pre> seems to work. Thanks for the tip.

Is it possible to place an Edit Box on a "main window" and access it from a child window without going through all kinds of hoops?????

Thanks in advance

do you mean hope?! Big Grin | :-D

Never heard about Window handles (or CEdit pointers?)?

nope....

I really meant "hoops"

I am fairly new to this and was hoping for an easy way to do this

Thanks

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.

or you could get the book "Learn C++ in 21 days"

I forgot to mention that I have been successfully writing and testing MFC Dialog type applications for quite a few years now, many with child windows. I have never had a reason for a child window to access any controls from any other windows so it never was an issue. Recently, that situation presented itself. To save time exploring how to do this, I posted here. My mother always said "if you can't say something nice, don't say anything at all". So please keep your condescending attitude to yourself Mike Mad | :mad:

Yeah, attitude aside, you don't want to. See the Mode-View-Controller Design Pattern[^] I figured, just because your mad, that's no excuse to develop lousy software.
