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

Accelerator doesnt work

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

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.

And where can I get a free compiler?

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 Smile | :)

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

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 Smile | :)

have fun.

No hurries, no worries.

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

2-May-05 1:54

hiho@ll

i'm using the outport source to export contact and appointments

my problem is i need to know a unique ID for a contact or appointment, to know if a contact or appointment has changed

outport uses InvokeHelper(0xf051, DISPATCH_METHOD, VT_EMPTY, NULL, parms, (LPCTSTR)fullname, &type);
to tell outlook to save the contacts or appointments in seperate files
(it's the same as if you do File->Save as) in outlook

the problem is it doesn't save a ID
so anybody knows how to determine the ID for a appointment and/or contact?

thx@ll

Receiving text strings over Bluetooth using a C-program and Visual C++

Hi, I am trying to use a C-program to read a virtual com port. Attached to this com port it is a Bluetooth Adapter(D-Link DBT 120). I am sending text strings from a bluetooth-unit and over to the Bluetooth adapter. I do manage to read the text strings with HyperTerminal, but I don't manage to read the text strings with C. I am using CreateFile to open the com-port, DCB to set the preferences(BaudRate, parity etc.) and ReadFile to read the Com-port. Anyone got an ide of what I can do? Thanks in advance!

. Plz tell where is my mistake.
Code is:

#include <conio.h>
#include <iostream.h>
#include <fstream.h>

void main()
{
struct computerspec
{
int ram;
int hdisk;
}compuspec;

cout<<"Enter the RAM capacity"<<endl;
cin>>compuspec.ram;

cout<<endl;
cout<<"enter the="" hard="" disk="" capacity"<<endl;
cin="">>compuspec.hdisk;

cout<

i dont see any problem in your code.
It must be working fine and must crate the file.

Check the file
1) if you are directly running the .exe, at the location of the exe file.
2) if you are executing from the vc projecy, then the file will be created at the location of workspace and project files i.e. where .dsw/.dsp exists.
