you can basically generate the outer framework like views, dialogs etc using mfc wizard and then incrementally transplant the code.

if you know WTL I think you this process should be easily and pretty straight forward and you should be able to understand the MFC stuff!!! ... I don't think there is any such tool to do this for you!

btw, welcome to MFC you made the smart choice Laugh | :laugh:

... ok this is an inside joke someone else who loves WTL and hate MFC...I am sure he will find his way to this page and be horrified!!! Poke tongue | ;-P

VC++ application is Multitasking?

Is the VC++ application multitasking?
If some message comes from outside to application while any function is running, what will happen?
The message processed first or it processed after completion of current function?

A newly created application is single threaded. It means that if you call a lenghty function, no windows messages will be processed (which means that your GUI will not respond until the function finishes). You need to start a new thread yourself to handle that situation.

SHFILEOPSTRUCT s = { 0 };
s.hwnd = m_hWnd;
s.wFunc = FO_COPY;
s.pTo = "C:\\destinationn\0";
s.pFrom = "C:\\source\\*\0";
s.fFlags = FOF_SILENT;
SHFileOperation( &s );

The key to this api is that the source and destination strings need to be double null terminated.

Run Oracle procedure using ADO connection in VC++

Karismatic24-Jul-07 19:15

24-Jul-07 19:15

I created a procedure:
procedure MyProc1(v_Ref_Comp_Id out abc.REF_COMP_ID%type)
is
begin
select ref_comp_id into v_Ref_Comp_Id from abc where ATTRIBUTE_ID = 1;
DBMS_OUTPUT.PUT_LINE('The value is::'||to_char(v_Ref_Comp_Id));
end myproc1;

Now i want to execute this procedure using ADO connection in VC++.I am trying like this-

::CoInitialize(NULL);
HRESULT hRes = pConn.CreateInstance((__uuidof(ADODB::Connection)));
HRESULT hResult;
try
{
if( TRUE != pConn->State == ADODB::adStateOpen )
{
strConn = "Provider=OraOLEDB.Oracle;User ID=ct;Password=matakali;Data Source=rcctrl;";
hResult = pConn->Open(strConn.AllocSysString (),"","",ADODB::adConnectUnspecified);
if(hResult != 0)
return false;
pComm.CreateInstance((__uuidof(ADODB::Command)));
pComm->ActiveConnection=pConn;

ADODB::_RecordsetPtr pRs;
pRs.CreateInstance((__uuidof(ADODB::Recordset)));

int nVal;
pComm->CommandText = "EXECUTE MYPROC1(nVal)";

pComm->Execute();//How can i retrive value in nVal

}
}
catch(_com_error &e)
{
_bstr_t bstrSource(e.Source());
_bstr_t bstrDescription(e.Description());
_bstr_t bstrError(e.Error());

CString err_msg;
err_msg.Format("Error : %ld\nDescription : %s\nSource : %s",
(LPCSTR)bstrError,(LPCSTR)bstrDescription,(LPCSTR)bstrSource );

AfxMessageBox(err_msg);

if(hResult != 0)
return false;
}
catch(CMemoryException *e)
{
e->ReportError(MB_OK);
e->Delete();
return false;
}

use mfc most of the time as in always Poke tongue | ;-P

... it's pointless to use wtl because of the lack of documentation and support.. you will find a lot more developers who will know mfc vs a few who know wtl

you can walk into any book store and find books on mfc

you can spend all your time developing in wtl only to find out you wasted time and effort when you need to bring new developer up to speed on wtl

this is my personal opinion there is nothing to stop you from using wtl for your own personal projects, but if there are going to be others working on a project pick mfc and forget about it!

the only virtues of wtl is your binary will be smaller...big deal with todays mass storage PCs and mega ram and faster CPUs!

How does web pages use the ActiveX's function?

how does script language to use my function exposed by IDispatch?for Example:there is a function declare as: long add(long n1,long n2),the script how to call this function?

Later buggers harm more.

simply create your automation object and call the function!

Your methods defined in IDispatch are exposed by default, if this is not working then you're doing something wrong with your COM object, check your idl, make sure your object has been registered and that you can see the interface using the oleview tool of your registered COM object!

GetFileAttributes for folders ?

Maximilien24-Jul-07 8:42

Maximilien

24-Jul-07 8:42

I'm trying to use GetFileAttributes to check if a folder is read-only ( for example, when a user right-click on a folder and select Properties and change the read-only attribute )

this is what I do :

DWORD dwAttr = GetFileAttributes(sPath);
if (dwAttr==INVALID_FILE_ATTRIBUTES)
{
  ASSERT( 0 );
}

if ( (dwAttr & FILE_ATTRIBUTE_DIRECTORY) )
{
  if(dwAttr & FILE_ATTRIBUTE_READONLY)
  {
    // Directory is read-only
    ASSERT( 0 );
  }
}

if I try on a file and it works :

CString sFileName( sPath);
sFileName+="tata.txt";

dwAttr = GetFileAttributes( sFileName );
if(dwAttr & FILE_ATTRIBUTE_READONLY)
{
    ASSERT( 0 );
    // Directory is read-only
}

I assume I'm doing something really stupid, but I cannot see it.

Thanks.

Max.

I'm guessing folders are controlled by an ACL, not the read-only attribute.

So what's the problem? What value does dwAttr have? If there is an error, have you called GetLastError()?

Re: GetFileAttributes for folders ?

Maximilien25-Jul-07 2:53

Maximilien

25-Jul-07 2:53

GetLastError() returns ERROR_SUCCESS

dwAttr is 0x00000010 ( FILE_ATTRIBUTE_DIRECTORY ), I would have expected the value to be 0x00000011 ( FILE_ATTRIBUTE_DIRECTORY and FILE_ATTRIBUTE_READONLY ).

Anyway, it's not an urgent issue for me or our product.

Thanks.
