Yeah, so the error states why the function failed.
I'll favour the other poster here. Like he asked: is it the same computer or a different one? If it's a different one, is there an audio device and the board has a speaker? (Do you see the volume control icon on the tray area?)

Errr.... I'm really NOT trying to be a wiseass... but does the server have a speaker?

I thought it were the same box which ran XP and the Server OS. I'll be shocked if they were different and one doesn't have a speaker. 
But how funnier can this it were the latter case.

It just sounded like something I'd do. I have a machine here that doesn't have external speakers, and the motherboard doesnt have one either, so it can't give the happy little beep when it boots. (Or any other time.)

from where are you calling that ?

Set the focus at the end of your WM_INITDIALOG handler, then return FALSE to prevent the system from setting focus to the default control.

In Dialog resource,
Tab numbers will be appear when you press Ctrl+D,
then you can set 1 to edit control. after run the application
automatically cursor will be appear on edit control.

In addition to the comments about the OnInitDialog function, use the CDialog::GotoDlgCtrl[^] function to actually set the focus. See here[^] on why SetFocus should not generally be used in dialogs.

hi everybody, the C++ fstream's write operation is Sync or aSync?
|
|
|
|
|
it's buffered, so you might not see the data in the file until the buffer flushes.
|
|
|
|
|
so the fstream's write operation will not be blocked?

I currently program in C# and decided to make a move to C++. I am finding it a little more difficult than I thought. I mean I am having trouble even reading a file. I am using XCode on Mac OS X Snow:
#include <cstdio>
#include <fstream>
#include <istream>
#include <ostream>
#include <iostream>
int main () {
using namespace std;
ifstream in("/Users/Dixon/MyFile.rtf");
if (not in)
perror("/Users/Dixon/MyFile.rtf");
else {
int x(0);
while (in >> x)
{
cout << x << '\n';
}
cout << "Ending....";
in.close();
}
}
Output:
[Switching to process 16406]
Running…
Ending....
Debugger stopped.
Program exited with status value:0.
Ok, now I understand I am not getting any errors when opening this file. The problem is it isn't reading anything from it. I have put 5 lines in there (just one word on each line). Now according to my book (Exploring C++ by Apress), this hsould work. This code is pretty much exactly from their book. Except in their book they used a list1302.in file as I used a RTF file. Maybe that is the problem? I really don't know what an IN file is exactly (coming from Windows world)

Ok im back tracking on my reading.. so the point is to read integers from a file. So I changed the words in my rtf file to just numbers and I still get nothing?
|
|
|
|
|
An rtf file includes formatting - so there is more in the file than just what you typed. Try using a plain text file with several integers typed into it.
|
|
|
|
|
I still can't seem to get it to work. I saved that RTF file as TXT and I also coded this to try to get it to work:
ofstream out("/Users/Dixon/test1.txt");
if (not out)
perror("/Users/Dixon/test1.txt");
else {
out << "1" << "2" << "3" << "4" << "5" << "6";
out.close();
ifstream in("/Users/Dixon/test1.txt");
if (not in)
perror("/Users/Dixon/test1.txt");
else {
int x(0);
while (in >> x)
{
cout << x << '\n';
}
in.close();
}
}
So I made it create a file with the words 123456 in it, close it then open it to read.. but it doesn't read!

I have also tried this: (from: http://www.cplusplus.com/doc/tutorial/files/[^])
#include <iostream>
#include <fstream>
#include <string>
int main () {
using namespace std;
string line;
ifstream myfile("/Users/Dixon/test1.txt");
if (myfile.is_open())
{
while (! myfile.eof())
{
getline(myfile,line);
cout << line << endl;
}
myfile.close();
}
else {
cout << "Unable to open file";
}
return 0;
}
But I seem to get:
[Switching to process 17059]
Running…
Exploration 13(17059) malloc: *** error for object 0x10000a700: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
Program received signal: “SIGABRT”.
sharedlibrary apply-load-rules all
(gdb)
If I change this:
while (! myfile.eof())
to:
while (myfile.eof() != false)
it runs but still does not read anything

Uhm... I tried something... I used NetBeans 6.8 instead of Xcode and the exact code compiled and ran just fine. It actually read the data. What could be the cause of that?
|
|
|
|
|
I don't know - I'm not familiar with either Xcode or NetBeans. Hopefully, someone else will have an idea for you.
|
|
|
|
|
Just being curious, but what do you use? I used Visual Studio for C#, but I wanted to try to find a program that would work on both windows and mac (thats where I found netbeans).
|
|
|
|
|
I've written code for a few different computers, but so far not the mac.
Lately I've been using:
Visual Studio for C++ on the PC,
CodeWarrior/Freescale for C cross compiled from the PC to a microcontroller, and
Visual C++ 1.52 plus some add-ons for C for an 80386EX embedded system.
None of this code is using iostreams & I have to consider myself weak in that area at the moment. I would have just looked at the responses you got to see what I could pick up, but seeing rtf rather than plain text was a glaring issue for me. In the last week I've had to deal with a couple of mismatched formatting issues.

Of these, only fstream and iostream are needed.

I'm wondering if there is something else this book is talking about? It says C++. But the code above is exactly what the book put in. Interesting...
I take it you didn't see my post before this one but it seems it works fine in netbeans, but in xcode it wouldn't work. I got the code that I was having trouble with to work perfect in netbeans. What could cause this?
