You might want to try searching for a Linux programming site. The Code Project is almost exclusively oriented towards Windows.
|
|
|
|
|
try the system() API.
int system(
const char *command
);
I believe thats a standard call available on Windows and Linux.

Of course this is the wrong forum for your question. Anyway, Linux provides fork and execv functions. Have fun with man to find out their usage.

You are creating object of the Interface IFileIO
rowdy_vc++ wrote: EDCService::IFileIO fio;
Do this:
EDCService fio;
Is this you want??

Do you realy need for IFileIO interface?
If you don't need it then remove it.
What declarations you made inside it?

I tried this::
IFileIO.h
<br />
#pragma once<br />
<br />
interface IFileIO<br />
{<br />
void setData(int xi);<br />
};
EDCService.h
#pragma once
#include "IFileIO.h"
<br />
class EDCService:public IFileIO<br />
{<br />
public:<br />
EDCService(){};<br />
int x;<br />
<br />
void setData(int xi)<br />
{<br />
x = xi;<br />
}<br />
};
Its works fine for me.
I can create instance like this
EDCService serviceObj;
Try it and let me know how it works

First Get Text from Control and then append your text to this text and then set this combined text to edit control
Got it?

At first I thought this was a joke but now I think you are serious. I hope programming is just a hobby for you.

I think you need to save previous data of your program on the registry or a file for read again.

I dont think my replay is funny?

manish is right, but there is a more efficient way:
send EM_SETSEL, -1, -1 to move the cursor to the end of the text
send EM_REPLACESEL, (TRUE/FALSE), (LPARAM) "your text" to insert the text at the cursor location (i.e. the end)

Hello all
I want to identify multiple monitors as we can do it by this way:
In Display Settings, by pressing Identify button.
Is there anyway to do this??
I am running on WinXP sp2
Thanks in advance.

use GetSystemMetrics(SM_CMONITORS) to detect if there is more than one monitor.
You can also use:
EnumDisplayMonitors() to enumarate monitors and retrieving the rect on screen.
GetMonitorInfo() to get information about a special monitor.
MonitorFromPoint() to get a handle to a monitor when you have a point.
You can use GDI to draw on screen or display a window to identify monitors

karle, Thanks for your kind reply
I want to Draw monitor number on top of all window and only number should be visible as system shows when we click on identify button of system settings property.
Any idea?

you could make a separate window for each number display and show one on each monitor.
make each window a "stay on top" window (see SetWindowPos, z-order argument) so it shows above all other windows.
and if all you want is the number, then make the window without any border or title bar and use color key transparency (see the WS_EX_LAYERED extended style, and the SetLayeredWindowAttributes() API using the LWA_COLORKEY flag).
