Hi. How do you set the path for your source files if they are in a different directory then the project directory in Visual C++.Net. I tried to go to Tools/Options/Projects and added the path to the list of VC++ source file directories but when I compile my code I still get link errors.

Hello!

If you get link errors, maybe include source file in project? Simply add it as a existing file to project.

Outputting binary numbers to the standard output stream

I am trying to output binary numbers to the standard stream. The problem is that I want to display them in the mathematically correct format.
Using 7.5 as a decimal example, to display it as:
111.1

Do I have to write my own function to convert these, or is there a simpler way?

Thanks,
Joe Hoppe

hi,

How can I check if a drive is Zip drive (and not a floppy drive). I know floppy is checked by DRIVE_REMOVABLE == GetDriveType(). What about Zip ?

regards

Try this:
(below code detects dvd)

<br />
<br />
STORAGE_MEDIA_TYPE GetDriveType(TCHAR A_chletter)<br />
{<br />
   DISK_GEOMETRY Geom[20];<br />
   DEVICE_MEDIA_INFO dinfo[20];<br />
   DWORD cb;            <br />
   GET_MEDIA_TYPES gmedia[20];<br />
<br />
   ZeroMemory(Geom, sizeof(Geom));<br />
   ZeroMemory(dinfo, sizeof(dinfo));<br />
   ZeroMemory(gmedia, sizeof(gmedia));<br />
<br />
   HANDLE hVolume = NULL;<br />
   CString drive_argument;<br />
   drive_argument.Format(_T("\\\\.\\%c:"), A_chletter);<br />
   <br />
   //wsprintf(szVolumeName, szVolumeFormat, cDriveLetter);       <br />
   hVolume = CreateFile(   (TCHAR*)(LPCTSTR)drive_argument,<br />
                           GENERIC_READ,<br />
                           FILE_SHARE_READ | FILE_SHARE_WRITE,<br />
                           NULL,<br />
                           OPEN_EXISTING,<br />
                           0,<br />
                           NULL );<br />
<br />
   if(DeviceIoControl (hVolume, IOCTL_STORAGE_GET_MEDIA_TYPES_EX, 0, 0, <br />
                                 gmedia, sizeof(gmedia), &cb, 0))<br />
   {<br />
      UINT MediaCharacteristics = gmedia[0].MediaInfo[0].DeviceSpecific.DiskInfo.MediaCharacteristics;<br />
      MediaCharacteristics = MediaCharacteristics;<br />
       CloseHandle(hVolume);<br />
      if(gmedia[0].DeviceType == FILE_DEVICE_DVD)//FILE_DEVICE_CD_ROM<br />
         AfxMessageBox("found dvd!");  <br />
      return (STORAGE_MEDIA_TYPE)(gmedia[0].MediaInfo[0].DeviceSpecific.DiskInfo.MediaType);<br />
   }<br />
   CloseHandle(hVolume);<br />
   return (STORAGE_MEDIA_TYPE)Unknown;<br />
}<br />
<br />

see _STORAGE_MEDIA_TYPE enumeration type.

I believe the API has a function that allows you to capture a window based on co-ordinates. Then, call GetWindowText. I forget what the API function is called tho.

handle RTF \field instructions in rich edit

Hi,

i have a problem... RTF has this special control word called \field and i'd like to use Microsoft's RichEdit control and handle this \field myself. But i can't seem to find anyway to make the RichEdit control break out to allow me to handle this control word. Currently the RichEdit control does understand this control word but it doesn't process it, it just gives out whatever fldrslt has. I'd like to use the control to have dynamic text.

currently MS Word uses this \field to do processing of time, author, date saved and so on to dyanmically change text on the word file when it is opened.

Example...

I create a dialog called CMyDialog.

Sometimes when I add it to to the project through the classwizard, it says it cant open the files "MyDialog.h" and "MyDialog.cpp". And other times it will say the the above files already contain remnants of that class.

I cant figure out what the problem is!

Thanks,
Daniel

You're adding classes with the same name over and again. If you remove a class from a project, go in and delete the files also.

Thats not the case. I know for a fact that the files dont exist.

Have you got any Anti-Virus software running, Norton Anti-virus used to cause similar problems with VS6 on one of my machines.

Have you got the latest VS6 service pack 5 installed?

windows systray balloon tooltip, need help

haritadala28-Jan-04 14:46

28-Jan-04 14:46

Hello all

I'm programming windows systray and want to put an icon in the sytray which can popup balloon tooltips. I'm using win2000 with visual studio6. The problem is the header file "shellapi.h" which I've seems like it doesn't support balloon tooltips. Here's the NOTIFYICONDATA structure I find in the hearder file

typedef struct _NOTIFYICONDATAA {
DWORD cbSize;
HWND hWnd;
UINT uID;
UINT uFlags;
UINT uCallbackMessage;
HICON hIcon;
CHAR szTip[64];
} NOTIFYICONDATAA, *PNOTIFYICONDATAA;

This structure doesn't have the members like "szInfo" which has to be used to popup balloon tooltip. I refer to microsoft docs where it says version>5 is needed, when I check my shell32.dll version it shows as >5.

Do I need to have new header file? If yes, where can I download from?

Can any one help me?

Many thanks for your help
Hari.

full duplex project

28-Jan-04 13:34

i thought the full duplex project was a voip application and was using it as a reference to build my own voip system, however i have now discovered that it only works over the data link layer and as such is not a voip system. Could you please tell how i could modify it, or how i would be able to implement a system which sends voice traffic over the IP layer using UDP as i have no idea where to start. i probably have to create and bind sockets with datagrams or something like that butim not sure how i would incorporate it into the project.

I would be very grateful for any help.

thanks
