Project Line Counter[^] is a powerful open source visual studio add-in.

it's main advantage is that it doesn't count the written code line but the generated code lines...

for instance

printf("Hello World");

and

printf(
    "Hello "
    "World");

produces the same number of code lines...

they also provide they sources[^] on codeproject...

//TestInherit.c<br />
<br />
#include<stdio.h><br />
<br />
typedef struct A<br />
{<br />
	int a;<br />
	char c;<br />
}A;<br />
<br />
typedef struct B:A<br />
{<br />
	int bb;<br />
}B;<br />
<br />
int main()<br />
{<br />
	printf("%d",sizeof(A),sizeof(B));<br />
}

Hi frends, I tried the above program.

Can any of u tell me the reason y it is not working??

It is simply a C program..

How can v support Inheritance in C??

Appu..

and the output as:

Somethings seem HARD to do, until we know how to do them.

this is certainly not C !!!

you tested this with a C++ compiler, in a .cpp file, didn't you ?!

How true.... Roll eyes | :rolleyes:

It's supposed to be hard, otherwise anybody could do it!

Because C doesn't have inheritance.

Why so ??

did you ever see in stroustrup's works a struct (or a union - it's exactly the same problem here) inheriting something else (struct, union or class) ????

Hi!

I am new to this group. I have started working on windows mobile 5.0 for Pocket PC recently. For my application on it I have been using Visual C++ (Not Embedded VC++). While creating the project I was in a confusion of which template I need to select under "File"----> "New"----->"Project------->""Visual C++"---------> "Smart Device"-------------->- ----------->ATL smart device project,
------------>MFC Smart Device application
------------>WIN32 Smart device project
------------->MFC smart device active x control
-------------->MFC smart device DLL

I am completely new to this environment. I wanted to know how to create this project and how to start working on it. Are there any good sites from where I can get the complete information? Please revert if any one have information about all these things. Waiting for your responses.

Regards,
Ravi

Wrapping text in CToolTipCtrl

There was a question from a reader in this forum, regarding wrapping the text in teh tooltip control. All you need to do is to set the tip width using SetMaxTipWidth function. CToolTipCtrl will wrap remaining text to next line bu automatically adjusting its height.

see the sample snippet

m_ToolTip.Create(this,0x40);
TOOLINFO ti;
ti.cbSize = sizeof(TOOLINFO);
ti.lpszText = "1. This is Item1\r\n2. This is Item1\r\n3. This is Item1";
ti.hinst = AfxGetInstanceHandle();
ti.hwnd = pWnd->GetSafeHwnd();
ti.uFlags = TTF_SUBCLASS | TTF_IDISHWND | TTF_TRANSPARENT ;
ti.uId = (UINT) pWnd->m_hWnd;
m_ToolTip.SendMessage(TTM_ADDTOOL, 0, (LPARAM) &ti);
m_ToolTip.SetDelayTime(2000,200);
m_ToolTip.SetTipBkColor(RGB(0xFF,0,0));
m_ToolTip.SetTipTextColor(RGB(0xFF,0xFF,0xFF));

// just for more accuracy Smile | :)

CDC* pDC = GetDC();
m_ToolTip.SetMaxTipWidth(pDC->GetTextExtent("1. This is Item1").cx);

Activex hWnd on CFormView

Hi,

I'm trying to add resizing to a CFormView in an MDI app, using the ResizableLib from the articles here on CodeProject. Everything works fine, except for ActiveX controls - I can't get a hWnd for an activex control when it's on a CFormView. Everything works fine with the same control(s) on a CDialog.

Can anyone tell me how to obtain the hWnd for an ActiveX control on a CFormView?

(It's an MDI app in VS .NET 2003)

Thanks,

Geoff.
