Is the file's type associated with your application?

MFC code:
<br />
CRegKey *r=new CRegKey(HKEY_CLASSES_ROOT);<br />
<br />
r->RecurseDeleteKey(".xyz");<br />
r->RecurseDeleteKey("xyzfile");<br />
<br />
r->Create(HKEY_CLASSES_ROOT,".xyz");<br />
r->SetStringValue("","xyzfile");<br />
r->Close();<br />
<br />
r->Create(HKEY_CLASSES_ROOT,"xyzfile");<br />
r->SetStringValue("","file description");<br />
r->Close();<br />
<br />
r->Create(HKEY_CLASSES_ROOT,"xyzfile\\shell\\open\\command");<br />
r->SetStringValue("","c:\\YourApplication.exe \"%1\"");<br />
r->Close();<br />
<br />
r->Create(HKEY_CLASSES_ROOT,"xyzfile\\DefaultIcon");<br />
r->SetStringValue("","c:\\YourApplication.ico");<br />
r->Close();<br />
<br />
delete r;<br />

that was of course association code.
You can also use .reg files during installation.
Look also at this methods:
CWinApp::EnableShellOpen
CWinApp::ParseCommandLine
CWinApp::ProcessShellCommand

Hi !
Our customers ask to add a dll from one of there partners to our project. (I name their dll 'rasterdll' to prevent misunderstandings). I got the libs, dlls and header files from them and add the necessary code to our application. There are 2 small parts I have to add, call a configuration dialog and a line by line processing (image processing; the rasterdll requests line by line and returns the modified lines). I have to say the rasterdll is called from one of our dll's.
Ok, now the problem. The dialog appears as expected but shows some errors (displays a math-calculated pattern, but the last 2 lines are destroyed (~10000 bytes))(The creator of this piece of software says that the buffer for this pattern is allocated via malloc in the rasterdll). For testing reasons I try the debug version of the rasterdll which displays the calculated pattern without any error. I go on with this debug version to the processing test. There are 2 situations: Sometimes the application crashes when I clear the buffer I got from the rasterdll (where I should store the input line), sometimes the process works as expected and I got a heap crash when I unload OUR dll (which calls rasterdll).
The rasterdll should be stable because it works in the applications that were made by the creator of the rasterdll. I think that the only problem can be an incompatibility. But we have exactly the same versions from visualstudio. I have no idea how to fix this problem. Debugging is nearly impossible and useless in my code. The config-dialog from the rasterdll is called by one line, no chance to make any mistakes. The creator of the rasterdll has no idea too. Hope anybody has some tips.
Many thanX,
Thomas

Hi!
I've made a post similar to this earlier. Due to misunderstanding I've rebuild the Q.
What could possible be wrong when CFtpConnection::GetFile(…) returns 5 (Access is denied). I know the file exists because I've just successfully made a CFtpConnection::PutFile(…). I'm using the same CFtpConnection object.
How could I have right to write to my ftp but no right to read.
Any tips are helpful…

Can you 'get' the file manually (i.e., without using code)?

Yes, and with any (tried two) other FTP-clients with same login. Both of them success.

Ok, let's see the relevant code that uses GetFile().

At first, this Upload function works OK:
<br />
bool CFTP::UploadFileToFolder(const CString &strFile, const CString &strFolder )<br />
{<br />
if( !bConnectionEstablished )<br />
{<br />
AfxMessageBox( "FTP - No server connected." );<br />
return false;<br />
}<br />
<br />
CFileFind Finder;<br />
CString strFileName;
<br />
if( Finder.FindFile( strFile ) )<br />
{<br />
Finder.FindNextFile();<br />
strFileName = Finder.GetFileName();<br />
Finder.Close();<br />
} <br />
<br />
BOOL bUploaded = m_pFtpConnection->PutFile(strFile, strFileName, FTP_TRANSFER_TYPE_BINARY, 1 );<br />
<br />
if( !bUploaded )<br />
Error( "CFTP::UploadFileToFolder(...)" );<br />
<br />
return true;<br />
}<br />
and (using the same CFtpConnection object, m_pFtpConnection)
this funk doesn't work:
<br />
bool CFTP::DownloadFile(const CString &strFromUrl, const CString &strLocalPath)<br />
{<br />
if( !bConnectionEstablished )<br />
{<br />
AfxMessageBox( "FTP - No server connected." );<br />
return false;<br />
}<br />
<br />
return m_pFtpConnection->GetFile( strFromUrl,
strLocalPath,
TRUE,<br />
FILE_ATTRIBUTE_NORMAL, FTP_TRANSFER_TYPE_BINARY, 1);<br />
}<br />

hi.
i wuould like to ask if anybody knows that pattern infermation of a cif video file (header, data etc).
also, is it possible to "divide" the cif video file into a series of still images (preferably bitmaps). if it is possible, how am i be able to do it. Our instructor required us to use Visual C++.
thanks in advance...

Hi,
I am writing an app which requires some CSocket derived objects to be created and processed in seperate threads. All was going well until I made the release build, when I started getting the SOCKET NOTIFICATION SINK errors (I was using CSocket within the CWinThread object).
OK, so after looking for a reason, I discover that it is to do with the CSocket not having an owner window to handle the messages (or some such - still a bit vague about it) and that it's a bit of a bug.
My workaround at the moment is to create a hidden dialog from the thread and put the CSocket derived class in here. This works great, except I get the pesky dialog appearing in the task manager. Since I plan to have several threads running, this is all a bit tacky.
Anyone got any better ideas? or failing that, anyone knwo how I can hide these dialogs without hiding the main window?
BTW using VC++ 6.0
Many Thanks

I don't think the problem lies within CSocket, because there is absolutely no connection between a CSocket and a window.
It must be something you are doing in your derived class.

I don't know if this is your problem, but I was having a problem yesterday with using a thread and CSocket. Microsoft has a confirmed bug in which certain members of CAsyncSocket don't get initialized correctly in a second thread (or something like that). The resolution was to put a call to the function I'm going to include below. This function can be a member of your class as long as you also make this static. Also this must be called before EVERY creation of a CSocket object in the second thread if you're doing it like I was in a loop.
void [YourClassName]::SocketThreadInit(void)
{
#ifndef _AFXDLL
#define _AFX_SOCK_THREAD_STATE AFX_MODULE_THREAD_STATE
#define _afxSockThreadState AfxGetModuleThreadState()
_AFX_SOCK_THREAD_STATE* pState = _afxSockThreadState;
if (pState->m_pmapSocketHandle == NULL)
pState->m_pmapSocketHandle = new CMapPtrToPtr;
if (pState->m_pmapDeadSockets == NULL)
pState->m_pmapDeadSockets = new CMapPtrToPtr;
if (pState->m_plistSocketNotifications == NULL)
pState->m_plistSocketNotifications = new CPtrList;
#endif
}

Thanks, this looks very helpful.
Any idea whether I call this before /after /instead of AfxSocketInit()?
Also, is it OK to declare a CSocket (derivative) as a member and then call it's Create() after running this, or should I just create it on the heap?
Thanks

In my app, it's called after AfxSocketInit(). I don't think it matters how you declare your CSocket object, as long as you call it before each Create in your new thread. In my app I allocate a CSocket object on the stack because it's only useful for the duration of the function.

I cant even get the fuction to run, it barfs at
#ifndef _AFXDLL
So I am at a real loss here. I tried removing this from my preprocessor defs and then I was in real trouble!
Are you actually creating /using your socket from the WinThread? or are you creating a CWnd for it?
Any chnace you can post some code up?
thanks,

If it is required under XP only, you may check ASPI interface. Otherwise quickest solution will be using 3rd party libraries, like that of binarymagics.com

Thanks other then VC++ which other plateform may be best

I don't know - I'm VC developer myself. But it should not matter - any Win32 development platform will have same limitation - well, maybe you will find free Delphi library for this. Another choice could be .Net - but it will limit your target platform anyway.

Maybe. I have written to CDs, and my programs work under windows 2000.
If you can limit yourself to windows XP, there is a cd burning interface that will be easy to use. Check out the limits of that, it might meet your needs.
You can get third party libraries to do the hard work. A little costly, but it might be worth it.
The hardest is what I did: write pure scsi commands to the device, handeling everything manually.
I've been meaning to write a CP artical about what I did (no code as my boss won't approve it, but I can give a lot of hints on what your design needs to account for). Let me know if this would be useful, I've been trying to find some motivation.
