When I would like to know how much time it takes to execute a particulary piece of code and this piece of code is very short I read the CPU time stamp twice. (Assuming that you are running a pentium class processor) The CPU time stamp is a 64 bits counter that runs on the same frequency as your CPU does. So with this you ll be able to measure very short times very accurate.
Oke this function is written in asm for the Borland compiler.
Hi all, i want to lock a region of a file over the 32bits limit 2GB. With _locking i can't, because it only supports 32bits filesize. Does anyone know how to lock a file in a position greater than 4gb?
Is your file already open? If not, you can open the file with a exclusive lock for the entire file using OF_SHARE_DENY_NONE. See the <a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/fs/openfile.asp" rel="nofollow">OpenFile</a>[<a target=_blank title='New Window' rel='nofollow' href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fileio/fs/openfile.asp">^</a>] API.
Hope this helps.

Am new to VC++, and am developing a simple software with a dll, and an .exe accessing the functions of this dll.
Am statically loading the DLL into my application,and the log shows the library being loaded successfully. However when I try to execute(debug) the application(.exe), it crashes out by flashing a Developer Studio error message saying: "Could not execute:Path not found(win32 error 3)".
I M WORKING ON AN MDI APPLICATION IN WHICH A TOOLBAR HAVING COMBOBOX ON THE SELECTION OF THE ITEM OF COMBOBOX I WANT TO UPDATE DATA OF THE CHILDVIEW .
I TRIED TO CREATE THE OBJECT OF CHILDFRAME INTO CHILDDOC AND IN VIEW GETDOCUMENT FUNCTION CALLED BUT ITS GIVING ASSERTION ERROR.
I TRIED TO MAKE FIEND FUNCTION INTO CHILDFRANE IT DOESNT WORK.
I TRIED TO USE GETDLGITEMID ITS GIVING ASSERTION ERROR .
I tried this code for Line1 too: m_RptReportInfo->Database->Tables->GetItem( 1 )->SetDataSource( _variant_t( (IDispatch *)m_pRec, true ) );
the problem is the program shows ALL records ... and NOT the filtered recs !!
1- Can u tell me what's wrong with my code ?!
2- ( ADO Question ):
say i have two _RecordsetPtr objects ..
for example: _Rec1, _Rec2 ..
_Recs1 fills by some records (by Open() mehod)
Is there anyway to copy some records from _Rec1 to _Rec2 ?!
for example i want to copy Record (pos) number 3, 10, 16 to _Rec2
I have a dialog box with id IDD_AGREE_FRAME_ABSTRACTION . This class's all cotrols are populated from the view class using one LoadDetails() function which is implemented inside the dialog class. I have added an edit box to this dialog. But when ever i am creating any variable of type:
1. CString and attaching it to the editbox through class wizard/manually. It's giving me a message "An unsupported operation was attempted". When i click that msg box the application is getting crashed.
2. CEdit then i am getting the message and the application is crashing.
When i am debugging the application the message box is coming in the DoDataExchange i for that particular entry for that editbox control.
I deleted the entry in the DoDataExchange for the control and just tried to set a its text by using GetDldItem(IDC_EDIT_BLDG_AGE)->SetWindowText("biswa") but again the application is crashing.
For all the cases when its crashing it's giving the error as "Unhandled exception in the app.exe(MFC42D.DLL):0x0000005: Access Violation."
I am really surprised why this is happening for this dialog where as for other dialog there is no problem when i do the same. Also when i am removing the the DDX_Text entry for the control causing the problem the whole application is running fine.
Please help me on this. This is really important for me. If you need any more information then just tell me i can give you the detail history for this.
When the dialog is created in the view class it calls the DoDataExchange function and when it excutes the line
DDX_Text(pDX,IDC_EDIT_BUILDING_AGE,m_BuildingAge) it crashes and when i remove the entry it works fine. Also as i said when directly try to access by it using GetDlgItem then also it crashes.
One more thing i want to say this class was not visible when opened the class wizard. So i deleted the .clw file and agained opened it. That class was then visible but when i selected that i got parsing error for one of entries of DoDataExchange function that is DDX_Dollar(.....). That is why i added entry for this control manually.
