Can we change the Volume Name Programatically?
For example we have NEW VOLUME( F: ) I want change this as KIRAN( F: ) Programatically?
Is it possible ,if then how we change?
|
|

I think you can try this:
SetVolumeLabel(_T("F:\\"), _T("KIRAN"));
I hope this works.

Can anybody tell me why some VC 6.0 pgms are failing in windows vista?
|
|
|
|
|
What type of failure you are talking about? There are changes/restriction in registry related API's.
There are few other changes. If you take care of this while porting, there should not be any problem.

It is better to use Windows Pipeline ( for stdioIn and stdioOut ) with the tellnet application. You can read the output ( or write to the input ) of console application to ( or from ) a win32 application through pipelining the stdio file of the console application.
|

|
Thank you so much for the solution.
Will you please give some more information related to Pipeline?
(Like, Which Class in Win32? What is stdio file?)
|
|
|
|
|
As per my knowledge there are no class in MFC for handling pipelineing you have to use windows API like CreatePipe. CreateProcess etc. For extra reference over them please look at allapi.net and search in http://msdn.microsoft.com/library/default.asp

I am trying to sand mail using my smtp server to yahoo or gmail its giving these errors.
554 error :smtp server not ready for data
554 error :Relay denied
i suppose my server requires authentication...
can anybody plss tell me how to do so
or can give me any sample code to do so
thans in advance

You didin't specified at which section you got the error.
If your server need an authentication then you just have to setup an smtp server in your PC and use zoneedit.com for setting up the MX Records.

Actually i m not getting ur point
The error comes when i send the DATA command
sTemp = "DATA\r\n";
m_wsSMTPServer.Send( (LPCTSTR)sTemp, sTemp.GetLength() );
if( !get_response( DATA_SUCCESS ) )
{
return FALSE;
}
it returns this error
554:No valid recipients access denied

Did you send MAIL FROM: and RCPT TO: commands succesfully? The error looks like your previous RCPT TO: failed.

I think that a clean solution implies the following steps:
(1) in your Dialog, you add a public method returning the check state (say CDialogA::GetCheck()).
(2) in the menu handler of the CMainFrame Window (or whatever...) you check the return value of the DoModal call:
(2.1) if it is IDOK, then you call CheckMenuItem, with MF_CHECKED or MF_UNCHECKED according to the return value of CDialogA::GetCheck.
(2.2) else you do nothing.
something such the following:
CDialogA dlgA(this);
if (dlgA.DoModal() == IDOK)
{
CMenu * pMenu = GetMenu();
UINT nCheck = dlgA.GetCheckA() == TRUE ? MF_CHECKED : MF_UNCHECKED;
pMenu->CheckMenuItem(IDM_A, MF_BYCOMMAND | nCheck);
}
hope that helps...

I create a member function with a CStringArray type variable in the argument list. I got the following error message
" no no copy constructor available for the class 'CStringArray'
Is there are any solutions or workarounds.
Thank you
|
|

You can not use pass an object of a CStringArray since it has no CopyContructor or assignment operator. One thing you can do is to pass a reference to the string array.
eg:
// use
void function( CStringArray& csStringArray_i )
{
}
// instead of
void function ( CStringArray csStringArray_i )
{
}
// One thing is to be noted down is not to pass any local variable of CStringArray to the function it may not work properly, especially playing with multiple threads.

CStringArray does not have a copy constructor. Use a reference instead...
bool PassingCStringArray( CStringArray<code>&</code> csaArray );

i am using this dll function to insert data in database but it give me following error...how to slove this can anybody there help me
setQuoteToDB(Timestamp,a,Market,Bid,Ask,d);
Error:cannot convert parameter 1 from 'const char *' to 'unsigned short ** '
|
|
|
|

It would be nice to explain your problem a litle bit better (and also to post some code to show how you are using the function).
To me the error is clear: you pass a pointer to a char array and the function needs an unsigned short** instead.

this is my code....can you just tell me how to convert it....this is dll function...
<br />
m_MainEdit=m_MainEdit + "<Price Change>" +" " + SessionId + "\t" + RequestId +"\t"+ a ; <br />
m_MainEdit=m_MainEdit + "\t"+ Market + "\t " + Bid + "\t " + b + " \t"+ Ask + "\t" +c +"\t "+ High + "\t";<br />
m_MainEdit=m_MainEdit + Low + "\t" + d + " "+ "\t" + Timestamp + "\r\n";<br />
<br />
UpdateData(FALSE);<br />
iLineCount=m_EditCtrl.GetLineCount();<br />
m_EditCtrl.LineScroll(iLineCount);<br />
<br />
<br />
<br />
_DBAccess db;<br />
db.setQuoteToDB(Timestamp,a,Market,Bid,Ask,d);<br />
