html help in vs7.0?

I converted several projects from vs6.0 to vs7.0.
In vs6 I used html as my default help.
This morning I discovered that none of the solutions in vs7 use html help. Whenever I press on F1 I get a message box saying it can't find the *.hlp file, which is of course true since html uses a compiled help file.
My question is: what do I need to do in order to change all my vs7 solutions to use html help?

Thanks,
Ilan

Just a suggestion: Start the macro recorder in Excel, then do what you want to do and look at the code the macro recorder has recorded.

please example sourec...

qsort+bsearch use

Hi,
Can you please let me know how to use this for the given char array.
char recode[][5]={"bare","barn","bard","Dame","born","dare","BARN","barn","dame","bORn"};
I am trying doing this however it is giving exception in execution
qsort( (char *)recode, sizeof(recode), (strlen(recode[1])+1), (int (*)(const void*, const void*))compare );
and
(char **)bsearch( (char *) &key, (char *)recode, sizeof(recode),
(strlen(recode[1])+1), (int (*)(const void*, const void*))compare )

Thank

sizeof(recode) should be, sizeof(recode)/5

Another way would be:

int  c( const void *e1, const void *e2 )
{
      return( strcmp((const char*)e1, (const char*)e2) );
}
 
// a is an array of char pointers
char*  a[] = {"bare","barn","bard","Dame","born","dare","BARN","barn","dame","bORn"};
 
long  i = -1,
      l =  sizeof(a[0]),  // 4 - size of char*
      n =  sizeof(a)/l;   // 40 / 4 = 10
 
qsort(a, n, l, c);  // sort array a, 10 elem, each 4 bytes in size
 
char  *k = "bard",
     **p = (char**)bsearch(&k, a, n, l, c);  // get pointer to matching key in a
 
if( p ) {
	// find index of match in sorted a (6)
	i = ((char*)p - (char*)a) / l;  // use byte arithmatic
	i = p - a;  // or, take shortcut based on p and a being known sizes
}

Thank for your input however following link error observed

error LNK2001: unresolved external symbol "int __cdecl compare(char * *,char * *)" (?compare@@YAHPAPAD0@Z)

You have to write a compare function for bsearch and qsort.
In my example this is int c( const void *e1, const void *e2 ) ...

Add Member Variable Wizard

Thank's lot done forget to change earlier declaration

We work previously with Visual C++ 6.0 and the Add Member Variable Wizard to create basic control works fine. We bought Visual C++ .net Standard and now it does not work.
When I right click on a dialog ressource (edit control for example) I have a menu to "add a variable". This menu opens a wizard to generate codes for this control ("Welcome to the Add Member Variable Wizard ") that adds only the declaration of the variable but don't create the relation between the ressource and the variable.
DDX_Check(pDX, IDC_TRACE_FILTER1, m_filter1);

Is there a limitation between the standard and the professional version or is there an update to fix that?

On the right side of the Wizard, there should be a Category combo box. Change it to Value.

I have seen that member variable wizard is not available in MFC extension DLL but it is working in an application (.exe).
Is there a workaround?

Thanks

It occurs after I have these codes in my program.

        m_pSocket = new CListenSocket();<br />
<br />
	if (m_pSocket->Create(PORT, SOCK_STREAM) == FALSE)<br />
	{<br />
    	AfxMessageBox("failure!");<br />
		m_pSocket->Close();<br />
<br />
	}<br />
<br />
	if (m_pSocket->Listen(1) == FALSE)<br />
	{<br />
	    if (m_pSocket->GetLastError() == WSAEWOULDBLOCK)<br />

Do you handle any user defined messages in COurProgramDlg or any other class related with it, then check their signature is correct. Or are you calling any function with a different calling conventions ?
