If you have a pointer to the CListCtrl object, you can simply use CWnd::SetFocus[^] this way:
m_pListCtrl.SetFocus();
If you don't have a pointer to the CListCtrl, you can use CWnd::GetDlgItem [^] on the parent window to obtain one.
CTheControlParent::SetFocusOnListCtrl()
{
CWnd* pWnd = GetDlgItem(THE_ID_OF_THE_LIST_CTRL);
if (pWnd != NULL)
pWnd->SetFocus()
}
Hope that helps,

Hello
I need to make a COM-DLL for use in VB and C# projects in vc6. I don't know how to start the vc project (what kind of new project), how i can see this dll from vb or c#. I need some documentation/sample.
Thanks,
Mihai

VC++ 6.0
NEW PROJECT: ATL COM AppWizard. (And a good book on the subject.)
Once you create/build it, it should be available to select in the commponts dialog in VB (as it is automaticaly register when you build it).
If you want the extension to be ocx instead of dll, then you need to change the output file extension (in the Project->Setting->Link[tab]) to ocx before building it.
For testing puposes, there is Tools->ActiveX Control Test Container.

I tried using
SetupDiGetDeviceRegistryProperty(dev_info,&DeviceInfoData,SPDRP_DEVTYPE,
&prop_datatype,prop_buffer,100,&req_bufsize);
Its gives an error SPDRP_DEVTYPE undeclared identifier. I checked the included "setupapi.h" and could not find SPDRP_DEVTYPE defined. But this is a property given in the msdn.
Is there any other function to access the DeviceType from the regisrty.
Regards,
Nripun

Maybe you need a more recent Platform SDK? I have that define in my setupapi.h file. Here's an extract:
#define SPDRP_ENUMERATOR_NAME (0x00000016) // Enumerator Name (R)
#define SPDRP_SECURITY (0x00000017) // Security (R/W, binary form)
#define SPDRP_SECURITY_SDS (0x00000018) // Security (W, SDS form)
#define SPDRP_DEVTYPE (0x00000019) // Device Type (R/W)
#define SPDRP_EXCLUSIVE (0x0000001A) // Device is exclusive-access (R/W)
#define SPDRP_CHARACTERISTICS (0x0000001B) // Device Characteristics (R/W)
#define SPDRP_ADDRESS (0x0000001C) // Device Address (R)

and in function STDMETHODIMP IMyIEExtention::SetSite(IUnknown *pUnkSite);
i write
<br />
m_pMyWB = (IWebBrowser2*)pUnkSite;<br />
IServiceProviderPtr pServProv(pUnkSite);<br />
pServProv->QueryService(SID_SWebBrowserApp, IID_IWebBrowser2, (void**)&m_pMyWB);<br />
m_pMyWB->QueryInterface(IID_IConnectionPointContainer, (void**)&m_pCPC);<br />
if (m_pCPC)<br />
{<br />
IConnectionPoint *spCP = NULL;<br />
hr = m_pCPC->FindConnectionPoint(DIID_DWebBrowserEvents2, &spCP);<br />
if (spCP)<br />
{<br />
spCP->Advise(reinterpret_cast<IDispatch*>(this), &m_dwCookie);<br />
}<br />
}<br />
{
then i create function Invoce

Other ways.... Hmm.. Import the Dll in your Mfc code using the #import directive, this will provide a COM Runtime wrapper just like VB provides like.
Have a look at this discussion:-

I am currently teaching myself c++ as a sort of hobby. I have no prior programming experience, but will have to program in the future. I have set a short term goal of learning cpp to the point that I am able to write an application that will interface with an instant messaging client and give automatic responses to certain incoming messages. Not necessarily a full blown chatbot, nothing fancy yet, but just for the learning experience of making one running program interact with another running program. I have no idea how this is done. I'm wondering if anybody has any input on what sort of subjects I should read up on? Can anybody describe how something like this is done in general?
Anything is appreciated

Code ia attached in the reply to the reply below
hi, i want to read a file for an ftp application from a remote location. so i used the CInternetFile::Read method to do so. but if i try to read more than 1 byte (say 512 bytes in one read ) then i get the number of bytes read through the return value as only. but the buffer in which i read the contents contains the numbe rof bytes specified and also contains some extra characters. eg:- i have a text file having only 42 characters when i read it by passing 50 as the number of bytes to be read to the Read method then the return value is 1 but the buffer contains the 42 bytes plus some extra characters. how can i solve this problem. Also i want to know the size of the file being copied . is there any function for the filesize. i tried using seekToEnd but it gave me an exception.

hi this is the codewhich i have written for the Download button handler
void CSmartFTP2View::OnDownload()
{
// TODO: Add your control notification handler code here
int i = m_list.GetCurSel( ) ; // get selection from list box
CString srcfile;
m_list.GetText ( i, srcfile ) ;
CString str;
CInternetFile * pfile;
CFile fp;
localtarget = localpath;
localtarget+= srcfile;
srcfile = remotepath + srcfile;
srcfile+='\0';
localtarget+='\0';
try
{
pfile = m_pftp->OpenFile(srcfile.operator LPCTSTR(), GENERIC_READ, FTP_TRANSFER_TYPE_BINARY, 1);
fp.Open(localtarget, CFile::modeCreate |CFile::modeReadWrite);
long size = pfile->Seek(0, CFile::end);
int pos=0, writebytes=0;
while( writebytes = pfile -> Read ( (void *)str.operator LPCTSTR(), 50 )!=0 )
{
fp.Write ( str, writebytes) ;
}
MessageBox("Download Successful");
}
catch ( CInternetException * pex )
{
MessageBox ( "Error in file copy" ) ;
pex -> Delete() ;
}
pfile -> Close( ) ;
fp.Close( ) ;
}
the localtarget will contain the local path and the srcfile has the remote path eg:- ftp://homepc/test.txt
