You can use interfaces in MSHTML.h

Find the window handle of your browser. and then by using below interfaces you can get whole HTML of the web page which is open.

IHTMLDocument2
IHTMLWindow2
IHTMLElementCollection
IID_IHTMLDocument2
IHTMLElement
etc..

how to hold the console application.

Hi,

I have created a win console application. When I run this application ..it just runs and disappears. If i use getch() before main return, then it waits for a key press. That is only when we press a key application closes.

So now I don’t want to use getch(). Is there any other way to hold the application, so that will not just disappear.

Thanks
Nandu

Several options here.

1. Open a command window first, then run your program from there.
2. Right-click on your executable and look at properties. Click on the Program tab, and clear the checkbox that says "Close on Exit".
3. If you have a shortcut (on the desktop for instance) do step 2 to the shortcut.

Hope that helps.

Hi,

I have tried the above points,

1. but still the window closes.
2. Right clicl on the exe dose not have an program tab or "close on exit" option as well.

So please suggest if there is any other option avilable.

Thanks
Nandu

Since you didn't indicate your operating system, I guess that could be the difference.

I'm using Windows XP (SP3) and I get the Program tab and on that tab there is a Close on exit checkbox.

If I could figure out how to attach an image, I'd put that in this message.

You could try adding system("Pause") at the end of your program.

Hi,

system("Pause") is working fine.

But I have a doubt, using system ("Pause")is similar like using getch(). In what way these two differs and which is the best option.

For the same question, some people suggest to use batch file to run the command line exe. But to use batch file we have a problem. This is because while executing command line exe...user also needs to provide some arguments as he needed. So if we use batch file user will not be able to provide the argument as need...he has to edit the batch each time he need to run the exe with different arguments.
So is there any way where user can give the arguments using batch file (rather than editing the batch file).

For now we have 3 options
1) Using getch() -- this is not the right approach
2) system ("pause") -- is this approach is right one?
3) If batch file is correct option -- how to address the batch file problem

Thanks
Nandu

You can pass command line arguments to batch files. Google about it and you can find lots of tutorial on how to use batch files.

I am not sure what exactly is your confusion and why are you worrying so much on such a simple issue. What do you mean by is system("pause") a correct approach? Can you define correct? Typically, correct is one that meets the requirements. What is the requirement in your case?

The main difference between 1 and 2 is for getch user will have to press a key then press enter to quit the application. system("pause") on the other hand needs just any key press to quit the application.

How to resize control when screen resolution changed?

A single document project, view class inheritance from CFromView. In view from, have many controls, edit control, static control...

When screen resolution changed or project runing from 16 by 10 screen to 4 by 3 screen, controls not printed right what printed right in 16 by 10 screen.

I can use
GetSystemMetrics(SM_CXFULLSCREEN) and GetSystemMetrics(SM_CYFULLSCREEN) to get screen resolution and then make controls size
to fix to current screen,but controls are to many in from. I want to make all controls by simple way.

rect.left = long((rect.left/1.28)*xRatio);
rect.top = long((rect.top/1.28)*yRatio);
rect.bottom = long((rect.bottom/1.28)*yRatio);

It's been a while for me messing around with property sheets, but the easiest way to hide the apply button would be applying the "PSH_NOAPPLYNOW" attribute.

Anyway I think you are using the wrong Control ID. I think it should be IDAPPLY or something like IDC_APPLY.
see http://msdn.microsoft.com/en-us/library/bb774538(VS.85).aspx?info=EXLINK[^]

some code from one of my ctor's for PSH_NOAPPLYNOW

<br />
	m_psh.dwFlags |= PSH_NOAPPLYNOW;			<br />
	m_psh.dwFlags &= ~PSH_HASHELP;				<br />
	m_dlgOptionsUsers.m_psp.dwFlags &= ~PSH_WIZARD;<br />
	m_dlgOptionsSMB.m_psp.dwFlags &= ~PSH_WIZARD;<br />

So long,

See if I got this right:

1. You don't want to create member variables
2. You don't want to use GetDlgItem
3. You want to get a CWnd pointer, or handle, to the control in your message handler
4. You are using MFC

There's no solution that satisfies those requirements.
Find something else to do.

...and you actually have 6 forms with 30(!) edit boxes.... OMG | :OMG:

For what it's worth...
if I ever had to do such a monster I would create a container that would hold all those control variables, e.g. a map that maps the ID of the control to the CEdit instance. I would also use ON_CONTROL_RANGE so I wouldn't have to write a message handler for each control.
