I haven't tested this, but this is the main program flow for it:

WIN32_FIND_DATA fd;

HANDLE h = FindFirstFile("A:\\*.*", &fd);
if(INVALID_HANDLE_VALUE == h) {
   // Didn't work, there are no diskette in the drive, 
   // or the inserted diskette is broken, not formatted, 
   // or some other error.
   DWORD dw = GetLastError();
   // Check dw for ERROR_NOT_READY or somthing similar.
   // The debugger will show you the exact eror code.
}
else FindClose(h);

Adjust the code for unicode, if you need to.

Then FindFirstFile() will return a valid HANDLE, and the "else" statement will be executed.
I'm not sure of what will happen if there is an empty diskette (without directories/files) inserted. You will have to try it out.

hi kakan.
I got this info.
I think it works.....

int ret =
GetVolumeInformation(_T("A:\\"), NULL,NULL,NULL,NULL,NULL,NULL,NULL);

if (ret == 0)
{
//Returns 21 on GetLastError() which is "Device Not Ready"

}

Hello WeirdAct.

I'm sure it will work. There are a number of ways to find out if there is a floppy inserted or not.

Go for this one, since it's simpler than the solution I suggested.

Have you tried CopyFile or CopyFileEx?

Then you will have to build your own driver that handles the low-level stuff, such as connecting to the pen drive, identify it, communicating with it, handle error conditions, disconnects, e.t.c. That's the hard part.
On top of that driver, you will have to build a file system. I haven't checked, but there must be quite a few source codes for the FAT32 file system on the net. Else, there is plenty of information about FAT32, so that part shouldn't be too hard to implement.
Good luck.

Thanks for your suggestions.

Yes Iam developing my own driver. I have already did some coding for identifying the drive and also communicating for some details.
I got the handle for the device.

Now i want to send folders into it.

If at all if you get any information please inform me.

Hello.

You will have to have some kind of file system on the pen drive. One (standard) way would be to use FAT32. That way, the directories and files on the pen drive will be readable by every machine/OS under the sun.

As I said before, there must be quite a few source codes for the FAT32 file system on the net. Else, there is plenty of information about FAT32, so that part shouldn't be too hard to implement.

Just Google for it. If you can't find a source on the net, its not that hard to implement yourself. Just make sure you handle the FAT table (and eventual copies of it) correct.
I once wrote a diskette file system repair program and that wasn't too hard.

I just wonder why would someone want to do this. Win 2K or above merely detects any USB storage device and assigns it a drive letter automatically. If the OS hasn't detected it, it means the device is not assigned with a drive letter and how pretty are you planning to copy stuff into it? In addition to that if there is a driver installed for a device, then there is no reason for someone not to use it.

I've a MFC Project devoloped using Gamebryo(NetImmerse)Engine. In this Project,
if I change a file for a parent, the clones not automatically updating. The change takes effect only after we save,close and reopen the file. The code for Reload i.e. changing a file is,

void CPerspectiveDoc::OnReload()
{
interactiveload = TRUE;
ChangedLoadedFile = true;

HTREEITEM selectednode = m_StructureView->GetTreeCtrl().GetSelectedItem();
CInsightNode* propkey = (CInsightNode*)m_StructureView->GetTreeCtrl().GetItemData(selectednode);
AddChildSG(propkey,(NiNode *)propkey->GetViewHandle());
}

AddChildSG is defined as,
unsigned int CPerspectiveDoc::AddChildSG(CInsightNode *Insight,NiNode *ParentNode)
{
NiNode *save;
unsigned int retval;

save = m_CurrentNode;
m_CurrentNode = ParentNode;
// get translate and rotate from CInsightNode
placetranslate = Insight->GetPosTrans();
placematrix = Insight->GetPosRotate();
retval = InteractiveAddNodeandSelect(Insight);
placetranslate.x = 0;
placetranslate.y = 0;
placetranslate.z = 0;
placematrix.MakeIdentity();
m_CurrentNode = save;
return retval;
}

Hello All,
I have a application like client can download updated version of my software and I have made that functionality to download my new file from the FTP.

But major problem is my new application takes more than 10 mins. to download to the client's computer and while downloading the new files the TASKMANAGER shows process Not Responding instead of Running.

In the background download process is running so why TASKMANAGER shows me message Not Responding.

Thanks in advance!!!

Use GetWindowPlacement.

WINDOWPLACEMENT wndpl;
AfxGetMainWnd()->GetWindowPlacement(&wndpl);
if ( wndpl.showCmd == SW_SHOWMAXIMIZED )
{
//maximized
}

There are, AFAIK, no limitaions using the runtime libraries in a service.
(Network access might be restricted, however).
So calling time(NULL) is perfectly alright.
