use killFocus()as many no of times as SetFocus()
never say die

|

can you show the code, how you have used setfocus.

Actually I am using the PropertySheets.In one of the propertyPage I have some edit controls.For each edit control there is some validation.I have handled these validations in the respective editcontrol's EN_KILLFOCUS event.
For one of the edit boxes the code is as follows:
void CMyFile::OnKillfocusEditRange()
{
CWnd *cwnd=GetFocus();
if(cwnd->GetDlgCtrlID() == IDCANCEL)
return;
else
CheckRanges(IDC_EDIT_RANGE);
}
void CMyFile::CheckRanges(int intID)
{
CString str;
double d1;
GetDlgItemText(intID,str);
d1=_tcstod(str,NULL);
if(d1 > 5 || d1< -5)
{
AfxMessageBox(_T("Range should be in 5 and -5");
pEdit = (CEdit *)GetDlgItem(intID);
pEdit->SetFocus();
}
}
I am doing the same checking even in the OnApply() .(After setfocus I return FALSE otherwise I return "return CPropertyPage::OnApply(); "
After running the application and when the message "Range should be in 5 and -5" is raised ,after clicking the Ok button of the AfxMessageBox ,if I move the cursor to open some other application there is a crash as "the memory cannot be read"

I doubt _tcstod is corrupting some memory.
Try commenting that line and just run through same flow i.e. use this code
void CMyFile::CheckRanges(int intID)
{
CString str;
double d1;
GetDlgItemText(intID,str);
if(1)
{
AfxMessageBox(_T("Range should be in 5 and -5");
pEdit = (CEdit *)GetDlgItem(intID);
pEdit->SetFocus();
}

What kind of crash? Where was the crash? Is there a call stack to the faulting code? Please be more specific and provide at least the answers to the above questions.

Which line has error?and did you use from breakpoint?
|
|
|
|
|
Maybe you are trying to set the focus to a control that exist no longer

What is it and wheres error?
|
|
|
|
|
this function having the problem.
m_arielapi.RequestQuote(sessionid,marketno,amount,tradetype,exchange,account,clientref);
the error is it it is showing "Invalid Market no." etc...
seems some problems with the comparison routine.
|
|
|
|
|
Its not sufficient for answer,right?he needs to say detaily

hi Priyanka,
we dont know what's the implementation of the RequestQuote function. then how we could predict the output.
check comparison statements inside the function.
can't you debug the code?
|
|
|
|

hello sorry may be my explanation is not very clear...
I am able to debug there is no error while run time,ihave button to connect to remote server and when it connect to server it gives me session id .
And when i click requestqoute button it should give me the qoute.But here it comes a msgbox that "invalid market no","invalid amount"
THIS IS FUNCTION DECLARATION
<br />
CString CArielAPI::RequestQuote(LPCTSTR SessionId, long MarketNo, LPCTSTR Amount, short TradeType, LPCTSTR Exchange, LPCTSTR Account, LPCTSTR ClientRef)<br />
{<br />
CString result;<br />
static BYTE parms[] =<br />
VTS_BSTR VTS_I4 VTS_BSTR VTS_I2 VTS_BSTR VTS_BSTR VTS_BSTR;<br />
InvokeHelper(0x5, DISPATCH_METHOD, VT_BSTR, (void*)&result, parms,<br />
SessionId, MarketNo, Amount, TradeType, Exchange, Account, ClientRef);<br />
return result;<br />
}<br />
THANKS

ok.
but the problem is all the decisions are taking inside the function which you are invoking... it's just passing the values after converting to BSTR.
so how could I make a raw assumption?
is the same code working witht some other modules? i.e the interface call?
