The problem with this is that it is illegal to distribute the dlls you listed. Those are DEBUG builds, and per the Microsoft License Agreement, you may not re-distribute them.

You must build a release build of your program, and then you are permitted to redistribute the release build of the dlls (using the vcredist as mentioned by others).

With Visual studio there is a tool called error look. You can enter the error code and it will show you the error string.

To take error lookup from visual studio take "tools menu->Error Lookup"

WSACreateEvent() creates a manual reset event, but I don't see anywhere
that you reset the event after waiting on it. Without resetting it,
you end up in a busy loop in between received datagrams.

*edit* Your WSAEnumNetworkEvents() call resets the event, but only every <br />
other time through the loop.  You'll probably want to fix the logic there :)<br />
Either use an auto-rest event or always call WSAEnumNetworkEvents() after the event<br />
is signaled, not just if there's a WSAEWOULDBLOCK error.

RegOpenKeyEx returning strange error

vipin_nvk22-Apr-08 20:43

I have been trying to open particular registry key to know the version of Outlook currently installed on the PC. Here is the piece of code

HKEY hKey;
CString strKey = _T("Outlook.Application\\CurVer");

if (::RegOpenKeyEx(HKEY_CLASSES_ROOT, strKey, 0, KEY_READ, &hKey) == ERROR_SUCCESS)
{
// do something
}
else
{
DWORD dwError = GetLastError();
}

The above piece of code fails to open the registry key and the GetLastError() returns error no. 122 which says "The data area passed to the system call is too small"

I have administrative privilege on the PC, but this piece of code fails to open the key, what could be the reason, and how do I interpret the error returned?

Thanx.

Change the parameter value instead of "KEY_READ" give "KEY_ALL_ACCESS"...

I'm not sure,whther this will work ..but try...

This piece of code works fine at my place but fails with the above mentioned error at the client's place, so I wanted to know as to what could lead to the ERROR_INSUFFICIENT_BUFFER error so that it can be fixed and then sent across to the client. Do you think changing access to KEY_ALL_ACCESS will really work?

As a matter of fact, that is a very bad suggestion. You should open a registry key only with the privileges that you may actually need.

Have you tried:

HKEY hKey;
 
LONG lResult = ::RegOpenKeyEx(HKEY_CLASSES_ROOT, _T("Outlook.Application\\CurVer"), 0, KEY_READ, &hKey);
if (lResult == ERROR_SUCCESS)
{
    // do something
}
else
{
    LPVOID lpMsgBuf;
 
    FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM,
                  NULL,
                  lResult,
                  MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),
                  (LPTSTR) &lpMsgBuf,
                  0,
                  NULL);
    ...
    LocalFree(lpMsgBuf);

Hello,

I have a class derived from CRichEditCtrl.
class CRICH : public CRichEditCtrl

In The above class I have a function
CRICH::GetCharPos()
{
SendMessage(EM_CHARFROMPOS,WPARAM ,LPARAM (5));
}

The above gives me Unhandled Exception but if I derive from CEdit I get the answer

What should I do to get the character position index from CPoint in CRichEditCtrl

Thanks
