Yes. NEVER ship an app that doesn't contain a framework to catch all exceptions and log their details, preferably with a custom dialog that sends the details to your office, so that you're able to do more than say 'it works here..... "

How to check if the DLL is Unicode or Ansi?

Given a dll, is there any Windows API or any utility, that can determine, if the DLL supports unicode strings or Ansi strings.

Thanks!

No.
Unicode/ANSI support is defined per function (via argument/return types, or by API doc's that state the function uses Unicode/ANSI internally) not per dll.

Can you specify your need little more in detail.

If the Dialog is showed using DoModal() then use EndDialog() to close the dialog and you can specify the return value...

As far as I perceive your query, you are trying to automatically close a dialog after some task is done and for this you want to fire a IDOK message.
Am I right?

if you want to let the user login automatically why do you need a login dialog.Just let the user access the application's functionality

CListCtrl :: FindItem()

Anu_Bala21-Aug-06 21:35

21-Aug-06 21:35

Hi,
Im searching for a calue in a listcontrol by using this
LVFINDINFO info;
int nIndex;
LPCTSTR lpszmyString ="LogFile";
info.flags = LVFI_PARTIAL|LVFI_STRING;
info.psz = lpszmyString;
if ((nIndex=pCtrl->FindItem(&info)) != -1)
{
Index = pCtrl->InsertItem(nIndex,Sno);
}
But here nIndex always returns -1, i want to serach for "LogFile" in listcontrol.Whats wrong with this?

Anu

prasad_som21-Aug-06 22:28

Are you sure , thers is an item, having label "LogFile" or which starts with "LogFile".
Otherwise there is no reason, it shouldn't work

MSDN description of flag
LVFI_PARTIAL :-Matches if the item text begins with the string pointed to by the psz member. This value implies use of LVFI_STRING.

In your case Item text begins with 1. Thats the problem.

See if its good for you(without create editbox because you dont need to it, find in list)

<br />
USES_CONVERSION;<br />
CEdit m_Edit;<br />
CString str22;<br />
TCHAR buffer[100];<br />
LVFINDINFO find1={0};<br />
<br />
m_Ctrl1.InsertItem(0,"test");<br />
m_Ctrl1.InsertItem(1,"test1");<br />
m_Ctrl1.InsertItem(0,"a"); <br />
m_Ctrl1.InsertItem(0,"b"); <br />
m_Ctrl1.InsertItem(0,"test"); <br />
m_Ctrl1.InsertItem(0,"a1"); <br />
m_Ctrl1.InsertItem(0,"b1"); <br />
m_Ctrl1.InsertItem(0,"test"); <br />
<br />
m_Edit.Create(WS_CHILD|WS_VISIBLE,CRect(0,0,100,23),this,1);<br />
m_Edit.SetWindowText("test");<br />
m_Edit.GetWindowText(str22);<br />
int index=-1;<br />
<br />
<br />
find1.psz = str22;<br />
find1.flags = LVFI_STRING;<br />
do<br />
{<br />
index=m_Ctrl1.FindItem(&find1,index);<br />
MessageBox(itoa(index,buffer,10));<br />
<br />
//m_Edit2.SetWindowText(buffer);//location from item in listctrl<br />
}while(index!=-1);<br />

int nIndex ;
int nstart = -1;

info.flags = LVFI_STRING;

pCtrl->SetItemText(Index,5,Model);
// pCtrl->SetItemText(Index,5,Modeltwo);
