Good point. 
I know that you believe that you understand what you think I said, but I am not sure you realize that what you heard is not what I meant. Anon.

There seems to have been a change in behaviour between VC6 and VS2005 builds when calling SetSel / EM_EXSETSEL in a rich edit control. I have code which emboldens certain lines of text, which used to work in VC6, but since moving to VS2005 has come up with the wrong results. The code is something like:
CString sText;
pEdit->GetWindowText(sText);
CString sSection = "SectionHeading";
int nPos = sText.Find(sSection);
int nPosEnd = nPos + sSection.GetLength();
pEdit->SetSel(nPos, nPosEnd);
If the heading is at the start of the text, then it's ok, else the selection is offset by the number of lines, which makes we think that the old code counted line breaks as two characters, but the new code counts a line break as one character. In the sText, the line breaks are definately two characters in both VC6 and VS8 builds.
Any ideas anyone?

While working with rich edit I found out that setting the selection back to begining is often necessary.
Since I work with VC6 I cannot comment on the "rest of the story".

Thanks for your reply. It's not that - I've found it:
VC6 used RichEdit 1.0 controls by default, whereas VS8 uses RichEdit 2.0 controls by default, so that is where the difference lies.
Version 1.0 seems to count line breaks as 2 chars, whereas 2.0 counts them as 1 char. I was getting my positions from my CString, which contains CR+LFs so counts line breaks as 2 chars.
I have changed my code to use the Find facility (EM_FINDTEXT/EM_FINDTEXTEX) in the RichEdit control, and all is now OK. (Not really sure why I didn't just use that in the first place!)

Paul,
After I posted my reply I realized that I was responding incorrectly.
Anyway, I observed same "problem" - I was searching for string and not counting the space after the string. Consequently my display was off few characters. ( I was changing the text color)
By accident - and I am sure you are aware of that - if you search rich text control for string using substring search it will give you the first match and it may not be what you are looking for.
Cheers

Have you tried using EM_FINDTEXT to find the text position instead
of copying the text to a CString?

Hi there, i have written a dialog based aplication in vc++, my dialog contains some edit box and checkbox controlls that a user can write strings into or check the box's.
I am looking for a way to save the value of whether a box was checked or not so that if the program shutdown or the computer rebooted the program would remember settings when it was next restarted.
any suggestions would be much apriciated.

Then you have to save relevant (status) data to disk.
There are many ways to do the above, for instance, you can use the registry or (if there is a big amount of data) build your own files.
If you're using MFC, then have a look at serialization topic http://msdn2.microsoft.com/en-us/library/6bz744w8(VS.80).aspx[^].
BTW if you're already dealing with a database, then store data inside it!.

A simple solution would be to use a .inf file or the registry to store your information. If you choose to use .inf file, look into functions like GetPrivateProfileSection(), etc in Windows SDK. If you choose to use the registry, look into registry functions like RegSaveKeyEx() or look into the class CRegKey in ATL.
Do the sync stuff in InitDialog().

You can use of registry for save datas or xml files.

But I thought it was the other one. Man, no wonder I'm confused!

There can only be one.

Maybe look in to overriding CStatusBar::CalcFixedLayout()
(see the MFC source for details) or use the SB_SETMINHEIGHT
message.

Thank you
Now it is working fine

how to create a Windows Console Applications.
and does it mean.
|
|
|
|
|
Consoles Applications are character mode ones (like the command prompt), see
http://msdn2.microsoft.com/en-us/library/ms682055.aspx[^]
BTW often the standard C (or C++) Run-Time I/O library is used (instead of Console Functions) to provide I/O to such applications.

dear all
#include <iostream>
using std::cout;
using std::endl;
void printArray(double [][4]);
int main()
{
double a[3][4] = {{0.3,0.4,0.5,0.6},{0.1,0.7,0.8,0.9},{0.11,0.12,0.13,0.14}};
printArray(a);
return 0;
}
void printArray(double a[][4])
{
for (int i = 1; i<=3; i++)
{
for (int j = 1; j j<=4; j++)
cout << a[i][j] << " ";
cout << endl;
}
}
why the result is changed in the end of one row?
thanks

Hey man, C++ arrays (like C ones) are 0-based, for instance
int a[3];
a[0] = 5;
a[1] = 2;
a[2] = 4;
a[3] = 12
hence check your iteration limits.
