1) u can use ShellExecute(NULL, NULL, "regsvr32.exe", <path to="" ocx="">, NULL, SW_HIDE);

2) you cant keep an ocx in the resourse and use it if you are doing static linking. if u are doing only dynamic lnking then, one thing you can do is to store the binaries from reourse into the harddisk and register from there.

While you can use ShellExecute() or CreateProcess() for this, you could also use LoadLibrary() and GetProcAddress() to call the exported DllRegisterServer() function.

Halo sir,

I went through your article which demonstrates the usage of UpdateResource(). Nice one. But from that I am unable to understand how do I do the same when I have imported it as a Binary resource into my MFC app. Its like I have an activeX DLL imported as a binary resource and it is a part of my executable now. I need to register the control to any machine on which the executable is run. I have understood that I could do it with ShellExecute() But I do not know how to use this resource!! Is copying this data to a file on the machine and registering it the only possible way? Can I not register it from within my program itself without copying this binary and creating a replica of the actual file?

Thanks for your help.
Aljechin.

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.

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...
