That won't work: some values might have no chances at all to be picked.

You'll need to roll your own. Something like this.

Make sure your ActiveX DLLs are registered. Are these functions graphical or non-graphical components? If they're graphical, you can easily use the dialog editor to put the controls into place, or you could use CWnd::CreateControl to create the controls.
If they're non-graphical components, there are basically two ways to use them. If your components expose interfaces with a vtable (IUnknown-based interface or dual interface), you can use the #import feature of Visual C++. The MSDN docs describe how they are used, and I'm sure you can dig something out about #import here on Codeproject. If not, Google is your friend.
If your component is dispatch only (no vtable), you don't need to #import the ActiveX DLL (unless you've defined structs or typedefs in the typelibrary). Then you can use the COleDispatchDriver class, which helps you to instantiate the component, as well as call methods and manipulate properties. This project could probably benefit you a lot: http://www.codeproject.com/com/xydispdriver.asp[^], as it simplifies the dispatch stuff a great deal.

I have designed the FTP client application using the WinInet classes . In that for storing the file on the FTP server i have used the CFtpConnection: PutFile(), but it is not retuning true and so the local file is not getting stored at the FTP server.The Error it is saying is that dwd =2(i.e ERROR_FILE_NOT_FOUND )Please help me out in this ....
Is there any other to store the file on the FTP server...
Thanks n Regards
Shikha

Why don't you work out why it's returning false, and fix it ?

Thanks for your immediate reply...
its showing ERROR_FILE_NOT_FOUND when i try to fix it using the GetLastError() but i cannot able to find out the reason..
why it need to find the file on the ftp server it should just get store the specified local file on the server side....
Thanks
Shikha

Perhaps it can't find the local file ? Or you don't have permission to create the file, so it's not found when it tries to write to it ?

Why was the local file not found?
Without seeing the relevant code, a helpful answer is going to be a guess at best.

HI Shikha!!! Are u passing the correct path of the file to be uploaded in the CFtpConnection::PutFile() function??? i am new to programming but i had developed a FTP client just a couple of months back.. so, i want u to see if you are passing the correct path in the PutFile() function. and like what Sir David Crow said, without having a look at ur code, we may not be able to give u the correct suggestions.. so, just see if u can post the sample of ur code...
i used the following lines of code to upload a file called as 'test.txt' residing on my 'C' drive.the file will be stored as 'ftptest.txt' on the FTP server.
<br />
CInternetSession sess(_T("MyFtpModule"));<br />
CFtpConnection* pConnect = NULL;<br />
<br />
pConnect = sess.GetFtpConnection(_T());<br />
<br />
BOOL bUploaded = pConnect->PutFile("C:\\test.txt","ftptest.txt",FTP_TRANSFER_TYPE_ASCII,1);
I want others to correct if i am wrong..
Regards, vijay Aroli.

You can ask any question you like regarding Visual C++ / MFC, but like I said If someone doesn't understand the question your asking, make it easier for the person trying to help you by providing sufficient information. And no one said the question you where asking was "silly".

If you'd fix your signature such that it did not run into your posts, people wouldn't get confused into thinking you are directing the comment towards them.

WTF !? 
if you have problem, first learn C/C++... it might solve much of your newbies basics questions.
and about who here is good or bad programmer, i don't think YOU are able to judge anyone about this.
the point here is that anybody can understand what you asked in your 1st question. so why do you react like this ?
when you don't understand a question, don't you ask for more precision to understand and help the guy ? that's what we all 3 did.
but instead of add precision, you're attacking us.

what do you mean by "check" ?
what do you want to do exactly ?
the CRT string functions are the ones like strxxx() but if you're a C++ coder,i suggest you to have a look at the std::string class instead...

|

Do you mean compare ? A char array is how C stores a string ( and what any string class is wrapping ). There are plenty of string classes, are you using std::string, CString, or something else ?
