Hello,
I have made a dll and for each of the classes included in the dll I have used the macro AFX_EXT_CLASS in the declaration of the class.
But if I have a .h file which has only consts then which macro should I use to indicate that this file is in the dll.

Nothing, just include the header file.

You want to export those consts through dll.

Since the constants are declared in the header file it self, you don't need to export it. Just include the header file.

if you just want to include the const, you just have to include the Header file, you don't have to anything or macro for including const, as contants defination would be available in the header file, I believe, this information would not be exported by DLL.

How to know whether the value is changed?
I've tried to override CMFCPropertyGridProperty::OnUpdateValue, but got a problem.
class MyProp : public CMFCPropertyGridProperty
{
...
};
BOOL CMyProp::OnUpdateValue()
{
if (!CMFCPropertyGridProperty::OnUpdateValue())
return FALSE;
if (IsValueChanged()) {
MessageBeep(MB_OK);
}
*m_pValue=GetValue().fltVal;
return TRUE;
}

I think even if same value is typed.It will return true.Because you tried to change the value .

i have a coding were i have to display the strings in the list box and if i select a particular string in the listbox a specific operation is done,i have put all these codings in a button click, but the listing of string in listbox takes place finally after all the operation inside the button click gets over,but i need the listing to be done first,where lies the problem???
for(j=0;j<n;j++)>
{
getlist(j,name); ->function call which fetches name
printf("\n%s\n",name);->this printing takes place
list.AddString((CString)name);
}
</n;j++)>
the below operation is done after the selection but listing doesn't happen
currentindx=list.GetCurSel();
SelectService(currentindx,&callback);

Sorry I didn't understand your problem. What do you want?.. as you have said you have put the code for adding string in List box on button click, than it going to happen at button click.
See programming always happen in sequence, so you have to decide sequence of your programming steps!

Why are you populating list box in button click. Can you populate the list box in OnInitDialog?

The cast is unnecessary.

But where are you asking for the text of the selected item? You need to call list.GetText(currentindx, ...) at some point.

How about tokenizing the string based on ',' delimiter and then extracting the characters after the '.' to get the extensions. You can tokenize the strings using strtok. There could be better ways of tokenizing the strings using Regular Expressions.
Somethings seem HARD to do, until we know how to do them.

You can also use string streams.
#include "string"
#include "vector"
#include "sstream"
...
string sResult(_T("Hello,can,you,split,me?"));
istringstream ResultParser( sResult );
string sToken;
vector vResults;
while ( getline( ResultParser, sToken, ',' ))
{
vResults.push_back( sToken );
}

Jijo.
