PING by itself is not a Windows API.
It is an executable called PING.EXE.

It internally uses ICMP APIs like IcmpSendEcho[^] or Icmp6SendEcho2[^].

The functions are declared in the header file Icmpapi.h.

Auto build increment with C++?

In the past I've worked on large teams and the build system we had in place would auto-increment the build number. At the moment I'm working on my own shareware project (written in C++, using VS2005) and I'd like to have Visual Studio auto-increment the build number for me (bonus points if it only increments the release version).

I started to do some digging and I've read that Visual Studio has this feature with .NET projects, but I haven't read anywhere about this being available in C++ projects, so my questions are:

* Does this exist for C++ project?
* If so, what are the steps needed?
* If not, are there any suggested tools or add-ins? What do some of the developers here use?

Thanks,

Jeff

If you don't insist on an "index" of builds you could use the __DATE__ and __TIME__ macros which give you the build date-time combined with some pre or maybe post build step that deletes the OBJ file or maybe updates the file time to make sure the file you put the creation of a build number into will get built every time (you can make the post or pre build step only in your release target if that suits you).

Yes, I already had searched but when I found lots of articles where a macro was written, I noticed that each article had lots comments about bugs, and instead of weeding through the umpteen articles I decided to post my question here to this forum.

So, back to original question, what do people here use?
(if you use one of the macros from one of the articles then please recommend it)

And does Visual Studio have an auto-increment feature available to C++ like managed projects do?

Thanks,

Jeff

Nah, I am old fashion and I manually change my build numbers.

No, unfortunately Visual Studio C++ users do not get those überlegen modern features.

This Microsoft Help and Support article has a sample build increment, I have never tried it.

Detecting the state of the Caps Lock key

I know about the win32 function calls to detect the caps lock key, but does anyone know if there is a cross platform way to do it? Is there anything in the standard library for checking that?

No, there is no standard C/C++ function for checking the status of the keyboard LED.

I don't really care about the keyboard LED. I really just want a way to tell when the caps lock button has been pressed.

Is there any way to do that?

Yes, but not cross-platform.

You should take a look at the strtok_s[^] function. There's even a very similar example as yours.

Problem with CComboBox::GetItemDataPtr

Hi,

I am getting a problem with the CComboBox::GetItemDataPtr function

i have the following code

TCHAR *szFilePath = new TCHAR[MAX_PATH + 1];
ZeroMemory(szFilePath ,MAX_PATH);
_tcscpy(szFilePath ,_T("C:\Documents and Settings\user\Desktop\Scrollbar.xml"));

int nIndex = m_Combo.AddString(_T("ScrollBar"));
m_Combo.SetItemDataPtr(n , szFilePath);

using the Above code am setting the ItemDataPtr to a Buffer.

On the Selection change event of ComboBox

i have the following code

void CRegDlg::OnCbnSelchangeCombo()
{
// TODO: Add your control notification handler code here
int nIndex = m_Combo.GetCurSel();
void *szFilePath = m_Combo.GetItemDataPtr(n);
}

but the GetItemDataPtr() in OnCbnSelchangeCombo always returns a Bad
pointer. I don't know what is the actual problem with my code. Is there anything i want to do to get the actual buffer from void*.

thanks

Are you intentionally not using double backslashes?

Shouldn't this be:

m_Combo.SetItemDataPtr(nIndex, szFilePath);

Nitheesh George wrote:

Shouldn't this be:

Hi all,
I have two applications in VC6.
I have to copy only a single dialog box (not the entire RC file) from one application
to other.
I know we can copy the RC file , but I dont want the entire RC file.
I want to copy only one dialog box from the one RC file and paste in other RC file.
Please suggest.
