Thanks in advance, CPallini!

I hope I will grasp basic skills and begin to ask questions in 2 monthes. I will read through the C# Programming Language, it is good it is not written by Bjarne again, which is hard to read. Smile | :)

regards,
George

Hi faradgi,

What kind of help are you expecting? Are you expecting the people over here to write a compiler for you? Sorry, that won't happen. You must do your own assignment and you may ask questions here, if you run into trouble.

Cut Assistant[^] does that, and is open source. (This one is on delphi, but do a little search there for something similar).

hi everyone,
good morning to all, i am savitri here. i am facing one problem in printing/reading the values from the card. please help me out.i used like this:
dStr="";
for(Ctr=0;Ctr<15;Ctr++)
{
dStr=dStr + CHAR(dataRead[Ctr]);
}
m_MemId=dStr;
in this m_MemId is a CString type and it is text box variable so the value of dStr is to print in that text box.
please help me out.

thanku,
savitri.

Call UpdateData(false); after m_MemId=dStr;. And then, there are real good reasons for you to Avoid UpdateData[^].

Why every object should contain hidden VPtr which points to VTable( which is static)?

Kishore JP7-Mar-08 18:37

Hello All,

I have a question.
Why every object of a class which contains virtual functions, should have a hidden VPtr in it? This VPtr will increase the size of object by 4 bytes. That VPtr will only point to the base address of VTable. Why an object requires this VPtr in it? Instead it can be put at class level like VTable.

Regards
Kishore

class level VTable, object level VPtr which points to VTable.

And why VPtr in objects, if not how the binding to the function happens if the object is typecasted to different Class types in its inheritance hierarchy.

Any way to always show horizontal scroll bar in CListCtrl?

I've tried:
1. ShowScrollBar(SB_HORZ)
It works, but when a item is added or removed, the scrollbar is automatically adjust (hide when not necessary).
There is another problem with this solution, though I've used xptheme.xml, it'll show non-xp style when first called.

2. WS_HSCROLL
Not work.

Getting handle of hidden window from another process

I have an EXE that has a hidden window.

Is it possible to obtain a handle to this window and post a WM_QUIT message.

The basic requirement that I have is that I need to un-install an application and before the process of un-install , I need to kill the process .

Something like this would work.

VOID YourClass::EnumerateWindows()
{
	EnumWindows(EnumWindowsProc,0);
}
BOOL CALLBACK EnumWindowsProc(HWND hWnd, LPARAM lParam)
{
	DWORD dwPID = 0;
	GetWindowThreadProcessId(hWnd,&dwPID);
	
	if(dwTargetPID == dwPID)
	{
		if (!(GetWindowLong(hWnd,GWL_STYLE) & WS_VISIBLE))
		{
			::PostMessage(hWnd,WM_CLOSE,0,0);
		}
	}

	return(TRUE);
}
