Hello,
I have a problem with my code that follows, everything works aye okay until I´m shutting the application down. My desktop resolution is then being set back to 1024x768x16 60Hz, and I have no idea why.
I´m aware that it´s quite alot of text to go through, but I would highly appreciate any suggestions on what might be wrong.
Edit:
The problem does not occur when I erase my ProcessIdle() function.
How come?
Thanks!

Feels good to answer myself 
well, the problem is solved, all I had to do was to put DestroyWindow(hWnd) UnregisterClass(CLASS_NAME, hInstance) in the end of WinMain().

How to execute a EXE remotely from machine

there would be a security problem 
you can install a server on machine1 which starts exe1 while running exe2 on machine2. in this case you have to connect to machine1, receive the request and then start exe2

having trouble reading what i have written in binary. i do beleive it is writing correctly (because there is a binary value in the text file it creates) but having trouble getting the binary value back into an array of 0's and 1's that i can look at.
well, the code i has seems to give me back all 1's no matter what.
please, if anyone knows about binary i/o!
thank you
#include <iostream>
#include <string>
#include <fstream>
using namespace std;
void main()
{
char textbit[8];
ifstream textfile;
textfile.open("bin.txt");
ofstream binaryfile ("realbin.bin", ios::out|ios::binary|ios::ate);
for (int i = 0; i < 8; i++) //get the 8 bytes from the plain text file
textbit[i] = textfile.get();
textfile.close();
for (int i = 0; i < 8; i++) //output them to screen
cout<

ok well i guess i got the i/o working
but now im kind of stuck
where i have
for (int x =0; x <2; x++)
that runs the loop 2 times and loads 2 8bit values into the binary file.
but i want this loop to run for the length of the input file.
whats the easy way to do that?
#include <iostream>
#include <string>
#include <fstream>
using namespace std;
void main()
{
char rtextbit[8];
char binarybyte =0; //chars are 8 bits 0 means 00000000
char textbit[8];
ifstream textfile;
textfile.open("bin.txt");
ofstream binaryfile ("realbin.txt", ios::out|ios::binary);
for (int x =0; x <2; x++)
{
for (int i = 0; i < 8; i++) //get the 8 bytes from the plain text file
textbit[i] = textfile.get();
cout<

Hi Group
Can anybody help me in rgds to Writing a code for Remote Shutdown using Pipes in VC++
Thanks in Advance

Hello,
I am using Windows 2000 Professional and VC++ 6.0 (MFC).
I have created a simple dialog based application.
I want to run this application when I click "Shut Down" from start menu.
How to achieve this?
TIA,
Regards,
Jahfer V P

You would need a separate application running that handles the WM_QUERYENDSESSION message. When that message is received, return 0, start the "dialog based application."

But, would the os allow launching a process when its in the process of shutdown? I think you have to abort the shutdown first, launch your application and call ExitWindows(...) again.

HI,
I am using ActiveX ( formula 1 Control grid .. same as Excel) , as i enter value ( 1/1/2004 etc in the cell. the ActiveX grid take it as a date and convert it in a numeric value ( i think ) , but when i get beck the Value from that cell it returns me the Interger( numeric) value.
How can i get that values back same as in 1/1/2004 format
Because i want to print it in same format.
other then this date format all integer and String values are working fine
thanks
Regards.

Hi,
I use a none MFC based Dialogbox, and I dont get an accelerator to run.
Here are my codesnippets:
int APIENTRY _tWinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPTSTR lpCmdLine,
int nCmdShow)
{
MSG msg;
HACCEL hAccelTable;
// Perform application initialization:
if (!InitInstance (hInstance, nCmdShow)) return FALSE;
if((hAccelTable = LoadAccelerators(hInstance, (LPCTSTR)IDC_STEALTHDIALOG)) == 0)
error(0, "Cant load Accelereators!");
// Main message loop:
while (GetMessage(&msg, NULL, 0, 0))
{
if (!TranslateAccelerator(msg.hwnd, hAccelTable, &msg)||
!IsDialogMessage(msg.hwnd,&msg) )
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}
return (int) msg.wParam;
}
Now: I created a new Accelerator, with the same ID as a button, cause they should do the same.
IDC_STEALTHDIALOG ACCELERATORS MOVEABLE PURE
BEGIN
"S", BTN_CONNECT, VIRTKEY, ALT, NOINVERT
END
I see that something happens to the button, it gets the focus, and theres no peep like when I press another combination than Alt+s.
But nothing happens. No action for the button. I also changed the ID of the accelerator, and put some code to its WM message, same result.
Whats wrong?

Hi
I am a 13 year old newbie to C++ and I really want to learn it. I already know HTML, XHTML, CSS and the basics of PHP. I already have a set of video tutorials but I need to know some stuff about c++ first.
1) What can you do with it (e.g. create programs, create webpages, etc)?
2) What is an IDE?
3) Are there any free C++ compilers out there (like Microsoft Visual C++)?
Thanks a lot
Rob

Also, is there anything else I need to know before learning it?
Thanks a lot guys.

A better question might be "What can you not do with it?"
Rob_BCFC wrote:

Integrated Development Environment. It's the editor, compiler, and linker all rolled into one.

Yes.

Ok thanks. So as you said, What can you not do with it?
And where can I get a free compiler?

Rob_BCFC wrote:

For example it cannot cook for you, or cut the grass or...
Ok just kidding 
No in fact it is used for developping applications. You can developp a large variety of aplpications from notepad to very complex programs or games... It depends a lot also of the knowledge of the programmer .
Rob_BCFC wrote:

Search on google for Dev-C++. It is a free IDE (so the graphical interface with the compiler and linker).

Thanks a lot mate. I really want to get into the computing industry and I think by learning C++ by the time I am 13 would be good.
|
|
|
|

If you learn it by yourself, I have one advice: don't try to make things that are too complicated at the begining. For example, if you want to make a very complicated programm at the begining, you will be disgusted... There are a lot of examples and tutorials on the web. But be patient, this won't come in one month of time...

hey,
C++ is one of the most powerful languages around in my opinion.
This means that you can do almost anything with C++, but it also means you have to be careful how to program. It's easier to mess up your code into "spaghetti" with C++ then eg. with C#.
Read up about descent O-O programming (Object Oriented). It's not that something is allowed in a language that it's ok to do it so.
For the rest good luck with your quest in learning C++, if you get stuck you can always ask here on codeproject and don't let me see your code on the daily wtf 
have fun.
No hurries, no worries.

I personally do not know of anything. Some languages are better suited for certain types of problems, however.

Thanks guys. Do you think I am too young to learn it though? Will it be to tough for me?
