Cluster size is very small usually, if NTFS then it can have maximum default value of 4 KB. It will be not problem to keep file size greater than 4KB. In Actual scenario, no application can create a huge amount of file, so we can ignore it as Richard said. If such a design is done then it should have a strong reason else your design is having some big problem.

I think his question was academic and since you can split a file into an infinite number of zero byte files (theoretically), the limit would be the number of clusters of the given partition.

Yes it seems to be, 5* for this guess

I think his question was purely academic, his (her?) responses would indicate that.

I have written application on Visual C++ . It is mainly MFC Application.
I can code .net also(with respect to C++ )
At runtime if .net framework is installed on target machine my MFC application has act as MFC .net application otherwise it act as Simple MFC application.
Is it possible ? ( I don`t want to compile with .net because many of our customers not dependent on .net )
Expecting Suggestions

If you have to work on machines without .NET...
And you are prepared to program in MFC...
And MFC works on machine with .NET...
Then where's your problem?

You need to handle the WM_SETFOCUS message and not call the base class handler to hide the carot.

I have a CTreeCtrl defined in my header with a instance of m_cTree. Here's a brief description of how the Tree looks:
[+] Reports (main Heading)
[+]Construction (child of Reports)
[+] Materials (child of Construction)
Materials Report.txt(the ".txt" is only to show you this is the actual report)
[+]Maintenance (child of Reports)
Maintenance Report.txt(the ".txt" is only to show you this is the actual report)
[+] Cost (child of Maintenance)
[+]Exspenses (child of Reports)
[+] Job Cost (child of Exspenses)
Exspenses Report.txt(the ".txt" is only to show you this is the actual report)
======================= end of example ======================
In OnNM_ClickTreeCtrl()
I cannot get the reports using this:
HTREEITEM hItem= m_cTree.GetSelectedItem();
HTREEITEM hChildItem = m_cTree.GetChildItem(hItem);
CString sSelText= m_cTree.GetItemText( hItem );
What is returns is whatever is selected including the button("[+]", the main heading, each child and finally the report. How do I only receive the click on the Reports themselves, not all the headings?
PLEASE use my example in your explaination, WITH(please) the appropriate code.
Thanks in advance.

Its better to handle this in the selection changed event(TVN_SELCHANGED) other wise, if some one operate the tree control through keyboard, your application wont work.
Larry Mills Sr wrote: How do I only receive the click on the Reports themselves, not all the headings?
You can use the item data corresponding to each item, to identify whether the items is report or not. I mean, while inserting the report, you should set the item data(SetItemData) as some value, say X. When the selection change occurs, retrive the item data correspoding to that item, check whether the item data is X.

|

Could you please provide a workable example for TVN_SELCHANGED?
Here's How I set up the TreeCtrl:
strItems[0]= _T("Reports");
strItems[1]= _T("Construction");
strItems[2]= _T("Materials");
HTREEITEM hReportsItemRoot= m_cTree.InsertItem(strItems[0]);
HTREEITEM hConstItemRoot= m_cTree.InsertItem(strItems[1], hReportsItemRoot);
HTREEITEM hMaterialsItemRoot= m_cTree.InsertItem(strItems[2],hConstItemRoot);
In your explaination, could you please use my example data, Please.

Hi
I have an application written in VB that checks whether a new wav file has been added to a folder by using the following:
MyFile = Dir("C:\MyDirectory\*.wav")
If MyFile contains a string, the file is then moved to another directory to manipulate.
I wish to do the same in VC (6.0) - have you any suggestions?
Thanks for any help that you can give!
Mike

Take a look at the FindFirstFile/FindNextFile[^] functions; they may be what you need.

Excellent - thanks very much - using the example got exactly what I wanted!
Thanks very much

knowing that I have imported the "msado15.dll" in my DLL (in the stdAfx.h file)
So someone know where is the problem and help me please ?

I added
#import <c:\Program Files\Common Files\system\ado\msado15.dll> rename("EOF", "adoEOF")and it compiled fine. What do you have before this statement?

what i did is like below :
i imported the msado15.idl (import "msado15.idl) in the begining of my IDL file (before the def of my Library) to use the ADO connection type as parameter of method.
But it compile with errors like i posted.

Are there any other ado include files in stdafx? if try moving it to after import line.

- No, there is no include ADO in stdAfx.h
- The two line :
#import "C:\Program Files\Fichiers communs\System\ado\msado15.dll" rename_namespace("Internal") rename( "EOF", "EndOfFile" )
#import "C:\Program Files\Fichiers communs\System\ado\msadox.dll"
are imported in most files of my project.
- My problem is related with the IDL file of my DLL and it begin when i try to put ADO connection as parameter of method in the IDL -> So i need to add the line import "msado15.idl"; and here i get about 2000 errors like this :
1>d:\travail\see_user_access\version 2.20\source\sac\see_ac_services\debug\msado15.tlh(1024) : error C2327: 'Internal::_ADO::Properties' : is not a type name, static, or enumerator

1>d:\travail\see_user_access\version 2.20\source\sac\see_ac_services\debug\msadox.tli(927) : error C2065: '_result' : undeclared identifier
So i hope i explained more my situation and you can find where is the problem?

Hi all!
I have a weird problem. I have an application written in c++ and compiled with visual studio.net and connecting to an Oracle with MS ODBC driver. Now the app is built under vs 9 and the ODBC driver is changed to the Oracle's one. (ODBC: Oracle in Orahome92). The connection string had to be changed to the Oracle's one syntax. Unfortunately the SQLDriverConnect crashes with access violation. In the Call stack the last source before asm is the delayhlp.cpp but nothing relevant info can be found. The interresting part is that I build a little sample application using the same Visual studio (9), same ODBC (oracle), same connection string ("Driver={Oracle ODBC Driver};DSN=db;Uid=admin;Pwd=admin;";) and there it works. No error with the function. Can anybody advice? Of course, if I missed some details, let me know.
-mfg-
