Okay, so with the DuplicateToken, do you need to close the returned token handle from it as well?

Seems so. Here's some sample code from MS (is written for .NET but using the Win32 API), in which CloseHandle is used on a handle returned by DuplicateToken...

Thanks for the quick response.

Also thanks for the sample which validates the answer.

Some in-house testing has showed the handle counts increasing, so we were coming to the same conclusion.

A couple of weeks back some guys helped me to create a dictionary file. Now I am looking to find a program that would remove duplcate words. I have not found one yet. Would anyone be willing to help me create a program that removes duplicate words? If, yes please have the code in console app format.

Many thanks

You would at least have to supply enough information to know what the dictionary file's data format is. We cna not remove anything if we don't knwo how to look it up, resport, save, etc. your existing data.

It is in the format of one word per line. The program takes a text document and scans the file for a space. Every time it finds a space it replaces it with a line return.

If you feed all your words into a ternary search tree, then enumerate the items in the tree when you are done, you will end up with a sorted list of words with no duplicates.
You can enumerate the tree items and the words can come out in aphabetically ascending order.

Do you think the ternary search tree will still work if there are 30+ of the same word?

Re: Remove duplicates

Blake Miller15-Jul-05 7:34

The ternary search tree will NOT accept duplicates.
It would hold all your words (less running out of memory, but you could also work around that) and there would only be a single copy of each word in the tree.
If you wanted to, you could associate a count with each word, so you would know how many were encountered in each document, but there would only be one copy of each unique word in
the tree itself. That is why I suggested it, you wanted to remove duplicates.

That's what uniq in Unix systems does. It requires the input file to be sorted, but you can of course pipe sort and uniq.

If command line utilies are acceptable, just download one of the many free kits of Unix tools for DOS/Windows. Then you can do, for example, something like:

C:\somewhere>type yourfile.txt | sort | uniq > output.txt

}
print join ("\n", sort keys %words);

I am trying to use a DLL in my Application . So i have been provided with the following

MyDll.dll
MyDll.h
MyDll.lib

I placed all these under a folder inside my Project called MyDll Files

I added the Library by going into Project-->Settings--> Link Tab and adding
DBusFiles/DBusDrv.lib

Now I am writing a Wrapper classes for the DLL functionality called CMyDllInterface

CMyDllInterface ::CMyDllInterface
{

// Some call to DLL
}

I get a message box with a message (with n different path names ) saying that it couldnt find the DLL . I know that if i put the dll inside WINNT\System32 it will work , but is there a way I can do it the other way ?

Engineering is the effort !

The DLL should go in the same directory as your EXE.

searches dll in the following sequence:

The directory from which the application loaded.
The current directory.
Windows 95 and Windows 98: The Windows system directory. Use theGetSystemDirectory function to get the path of this directory.
Windows NT: The 32-bit Windows system directory. Use the GetSystemDirectory function to get the path of this directory. The name of this directory is SYSTEM32.

Windows NT: The 16-bit Windows system directory. There is no function that obtains the path of this directory, but it is searched. The name of this directory is SYSTEM.
The Windows directory. Use theGetWindowsDirectory function to get the path of this directory.
The directories that are listed in the PATH environment variable.

string in .mc file or as IDS_ resource

To have string in my application, i can put it inside a .mc file or add it as a string resource(IDS_). So can anyone tell me the difference in these two approach.

Thanks for your time.

AFAIK message tables are only useful if you're going to be writing to the NT event log. Otherwise, the string table is far easier to use.

I think we can have support for multiple language with the same file, have not seen any sample code (multi langs in .mc file) doing that till now.

combobox event in propertypage

15-Jul-05 4:08

I've got a CFormView-derived class. It contains a CPropertySheet member, that is, it is not a CPropertySheet-derived class. On one page of the property sheet there is a combobox.
So how can I treat a CBN_SELCHANGE event from that combobox within the View class?

Pseudocode:

<br />
public CMyView : CFormView<br />
{<br />
   CPropertySheet* m_sheet;<br />
   CPropertyPage* m_page;   // this page contains a combobox<br />
}<br />
...<br />
   m_sheet->AddPage(m_page);<br />
...<br />
void CMyView::ComboBoxHandlerFcn<br />
{<br />
   DoSomething();<br />
}<br />

Right, so I would have to handle the event in my CPropertySheet.
Since I do not have a derived CPropertySheet class, I wish to handle it within the view class!
