ftp and gopher have related finder classes of CFtpFileFind and CGopherFileFind respectively.
but how to find files with http protocol?
is it impossible?
|
|
|
|
|
I might be talking complete rubbish, but I don't think HTTP servers support searching. I've certainly never come across a program that lets you do it, and I've come across plenty of FTP ones.
|
|
|
|
|
The HTTP protocol does not offer this. Perhaps the web server provides a search or directory service you can use.
Cheers, M

But since it is includeh10 we will never know. Hope I could help anyway, see you next time.

after some time using of application its becomes so slow,even if i restore it from minimize state its take some time to display the controls of dialog box.
and the memory usage of application increase and increase.
please tell me how can i reduce the memory usage of application,and make it stable wheather its use or long time,
please tell me how can i resolve the problem of slow responding or not responding.
thanks in advance.

| Try Googling "memory leaks". Steve

As Steve suggested, your application probably doesn't perform well the necessary cleanup, i.e. keeps allocating new objects without calling delete on the 'dead' ones.
Correct handling of dynamic memory is one of the major duties of the C/C++ developer.
 If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Build a debug version, start its debugging (F5),
then close the app and observe the output window in VS.
Usually you can even jump to the source, like ... = new ...,
just by a double click at a "memory leak" line there Check your definition of Irrationality[ ^]

OK Was it an output of the Debug vesrsion (configuration) of your application ?
When yes - there are no direct references to the classical memory leaks (by new).
However it would be possible (for example),
that you do not release other kinds of the resources,
such as HPEN, HFILE, HXXX... ,
or you initialize something twice without releasing...
You could try to analyze the code (subject: symmetry of allocation/deallocation),
or use the special tools (when your code is to big for you to analyze)... Check your definition of Irrationality[ ^]

From 'View' Menu Choose to see Resource 'View Panel' in your IDE
In the Resource View Panel Expand Items and right click the Dialog Branch and Choose 'Add Resource' and press New Button of add Resource Dialog.
After your dialog has created you can see it in Resource Designer when ever you want by Double Clicking on it in Resource View Panel.
After You do all these Right Click on your Dialog in Resource Designed and choose 'Add Class'
fill the class field with a name (e.g. "CTemp1Dlg")and before Finishing the wizard attention the names of .Cpp File and .h file which is created for you through wizard (here : Temp1Dlg.h and Temp1Dlg.cpp)
now include the Temp1Dlg.h File created in previous step in your Code which you want to Modal your Dialog.
in the method you want to Modal your Dialog write the below code:
CTemp1Dlg dlgMyDialog(this);
dlgMyDialog.DoModal();

Ok Please Don't hesitate to ask any question ,But I could not promise if I could answer them all.
Here is a list of update books you may like to use, How ever mostl of MFC guide books found in the net are old ones but they could be useful too because the bases are the same:

By the way for those who are new to MFC, How Do I? Video Series[^] would be interesting.
