Calling GetBuffer and ReleaseBuffer is completely unnecessary. The following will work:
CString FName = "10";
int n = atoi(FName);
It works because CString has an operator LPCTSTR.

Ohh...
GetBuffer and ReleaseBuffer is mostly used where you want to modify data of the CString instead of Format.

Use _ttoi() function

Try this way.
CString strInteger(_T("302"));<br />
int iValue = _ttoi(strInteger);
i value will be 302

You have recieved several answers to your question and they all show you how to convert a string to integer. Take note that this is not type casting, it is conversion from one form to another. This is important because you could type cast a string to an integer value but the value would not be the value entered in the string. It would take the individule byes and assume they are parts of the final number you are seeking.
char str = "AB"; // 'A' = 0x41, 'B' = 0x42
short n = (short*)(str); // n = 0x4241 = 16961
If you are wondering about the reversal of the numbers durring the type casting, then you need to go look up big endian and little endian on the Web.

Hi guys !
In windows service code
I have following code in function void CServiceModule::Run()
CDatabase DB;
try
{
if( !DB.IsOpen() )
DB.Open("PrinterDB");
}
catch( CDBException* e )
{
char Buffer[256]="";
AfxMessageBox(e->m_strError);
}
DB.Close();
here PrinterDB is the name of my DSN pointing to an MDB file.
Now when I run it as normal executable it works properly.
but When I run it as service (from MMC start service) connect to DB fails.
Please help me...

actually i wanted to know how we can setup flex and bison with visual c++
because when i tried to compile lex.yy.c file with visual c++ it shows many errors not recognizing c operators 'exit','malloc','realloc','free'

It doesn't show how to use Bison with VC++, which is what the OP requested.

I am using word automation to get the text in a word document however, i face problems when the document is already open. Is there a way (coding) to check if that document is open and if open, close it?
|
|
|
|

Try below code.
Word::_ApplicationPtr wdPtr;<br />
Word::_Application::get_Application( &wdPtr); <br />
if ( NULL == wdPtr ) wdPtr.CreateInstance(__uuidof(Word::Application)); <br />
<br />
for (int i=0; i<wdPtr->Documents->Count; i++) {<br />
Word::_DocumentPtr dPtr = wdPtr->Documents->Item(i);<br />
if ( dPtr->Name == "whatever you are looking for" )<br />
dPtr->Close(); <br />
}

Once you close the socket the port is automatically freed...So take care of closing of socket.
shuchigo_jane wrote: is there a command u can use in the command prompt?
you can check it while tring to bind to the specific port(i mean 2000) is free or not if it is free you can able to bind it.
shuchigo_jane wrote: if it is still bound can u free it from there?
You just can't because the port is available only if it is free and is free after closing the socket binded to that port or killing the application which uses that port.

Create the pointer of sencond dialog in the first first dialog so that all the member varbales of seocnd dialog can be initialised from first dialog.
Now when you show get the string pass it to the member varibale of Second Dialog CString varibale and with the same object you can display the dialog.
For eg.
You have two dialogs
CFirstDialog and CSecondDialog and you are having CString varibale in Second Dialog class as m_frstDlgString
In first dialog IMplementation file write:
CSecondDialog *m_sDlg;
<br />
m_sDlg = new CSecondDialog();<br />
m_sDlg->m_frstDlgString = temp1;<br />
m_sDlg->DoModal();<br />
<br />
<br />

You will have to declare a pointer of the first class in the header file of the second dialog(assuming you have a class associated to the dlg's).
Now when you are calling the second dialog do this :
CMySecondDlg *mySec=new CMySecondDlg();
mySec->oldPtr=this;
mysec->DoModal();
(Do not forget to include the header files)
Now if your string is defined as CString myString in the first class:
AfxMessageBox(oldPtr->myString);
