Re: Restrict user from accessing drives David Crow18-Apr-03 5:01 David Crow 18-Apr-03 5:01  Are you wanting to prevent a user from opening up their own D: drive?

Suppose I have a istream and I want to read an integer from a istream. If the length is 0 and I think the stream is correpted and I won't like any other operations on the stream later. So I think I can set the state of the stream. The following is my sample code. I want to know whether my solution is correct? Are there some other things to consider? Source codes: -------- int data; /** return value is used to indicate whether the return value is correct. */ bool A::Read (std::istream& is) { is.exceptions(ios::failbit|ios::eofbit); try { is.read ((char*)&data, sizeof (data)); if (!data) { is.setstate (ios::failbit); return false; } } catch (ios::failure e) { return false; } return true; } -------- Thanks in advance, George Two programs - Same file Instantaneous write and read. Pecan20417-Apr-03 16:52 Pecan204 17-Apr-03 16:52  Can someone suggest a method to accomplish writing to a file and at that moment another program would read that same data for its use. The program is writing a line of floats to just generate data while the other program needs to read and process it. Using two seperate executables and an ascii file led to apparent file locking issues. Thanks for any suggestions. Ken Re: Two programs - Same file Instantaneous write and read.

John M. Drescher17-Apr-03 18:09 John M. Drescher 17-Apr-03 18:09  You can do this with a memory mapped file and a named event. Create a named event and open it in both applications. Set it in one thread to signal that the other can read the data. When the data is read reset the event. http://www.codeproject.com/win32/cmemmap.asp[^] John Re: Two programs - Same file Instantaneous write and read.

David Crow18-Apr-03 5:08 David Crow 18-Apr-03 5:08  Use an “event” — a synchronization object that allows one thread to notify another that an event has occurred. Events are useful when a thread needs to know when to perform its task. For example, a thread that copies data to a data archive would need to be notified when new data is available. Look for CreateEvent(), SetEvent(), WaitForSingleObject(), etc. Can't write to registry when I use CRegKey... IrishSonic17-Apr-03 14:56 IrishSonic 17-Apr-03 14:56  Hiya when I use these Win32 functions for the registry: #define REGKEY_SOFTWARE "Pass1" #define REGKEY_DIRECTORY_PATH "Software\\Projects\\Password" rc = RegOpenKeyEx( HKEY_LOCAL_MACHINE, REGKEY_DIRECTORY_PATH, 0, KEY_QUERY_VALUE | KEY_SET_VALUE, &hKeyParent ); and then this: rc = RegSetValueEx( hKeyParent, _T("Project Password"), 0, REG_SZ, (const unsigned char *)(REGKEY_SOFTWARE), sizeof( REGKEY_SOFTWARE) ); it is fine. It inserts my key into the registry no problem. But when I swop RegOpenKeyEx for: CRegKey *pRegKey; pRegKey = new CRegKey; rc = pRegKey->Open( hKeyParent, REGKEY_DIRECTORY_PATH, KEY_READ | KEY_WRITE ); it doesn't put my key in. What am I doing wrong with this function?? I have error checking on Open and it returns no errors.. Thanks, grahamoj. Re: Can't write to registry when I use CRegKey... David Crow18-Apr-03 4:35 David Crow 18-Apr-03 4:35  You must follow the pRegKey->Open() call with a call to either pRegKey->SetKeyValue() or pRegKey->SetValue(). Why are you using a CRegKey pointer? Just declare it on the stack. Allocating little bits of memory like this is unnecessarily wasteful. Use new only when you have a compelling reason to do so. MFC: How to make CView appear outside CFrame? vawksel17-Apr-03 14:26 vawksel 17-Apr-03 14:26  How can you make a CView window appear OUTSIDE the CFrame (CMainFrame?). The goal is to create a CMainFrame with multiple different CView classes that appear floating on the desktop that all attach to the same CDoc. - Jeff Sidlosky jsidlosky@yahoo.com Re: MFC: How to make CView appear outside CFrame? valikac17-Apr-03 16:19 valikac 17-Apr-03 16:19  So you basically want a whole separate window. One solution is to call the view class Create(). Try with the different window properties.

Here's a pretty simple program: void main(void) { HRESULT hr = URLDownloadToFile(NULL, "http://www.google.com", "c:\\output.htm", 0, NULL) ; if (SUCCEEDED(hr)) { printf("success\n") ; } else { printf("failed\n") ; } } For some reason the URLDownloadToFile call fails. If I put any of a host of other urls in the call the download works perfectly, however, for www.google.com and several other pages (www.yahoo.es for one) the function just refuses to work. I'm completely baffled by this. I can't find any commonality between the pages that fail and I know that www.google.com does indeed exist on the internet. Has anyone else had problems using the URLDownloadToFile function? Thanks Re: URLDownloadToFile is making me mad Michael Dunn17-Apr-03 11:48 Michael Dunn 17-Apr-03 11:48  It would help to know the error returned by URLDownloadToFile(). One possibility is that the server doesn't allow downloads without a proper HTTP_REFERER header, which is not present when using that API. --Mike--    THERE IS NO     THERE IS NO    BUT THERE IS MAGIC PIXIE DUST  BUSINESS GENIE  CODE PROJECT Homepage | RightClick-Encrypt | 1ClickPicGrabber "You have Erica on the brain" - Jon Sagara to me Re: URLDownloadToFile is making me mad Big Art17-Apr-03 12:18 Big Art 17-Apr-03 12:18  I experimented with this method and got the same problem for google and a few other sites. The error code is 0x800401e4 which translates to "Invalid syntax"???? Art Re: URLDownloadToFile is making me mad MattyBee18-Apr-03 4:00 MattyBee 18-Apr-03 4:00  That's right, 0x800401e4 is MK_E_SYNTAX. MSDN describes this error for a different URL Moniker function (they don't even list it as a return value for URLDownloadToFile) and it says: A moniker could not be created because szURL does not correspond to valid URL syntax for a full or partial URL. This is uncommon, because most parsing of the URL occurs during binding and because the syntax for URLs is extremely flexible. So what's going on? I can't believe that I just can't use URLDownloadToFile at all in my application because it just doesn't download certain pages... Also I don't think the problem has to do with a bad header to www.google.com because I can get a response from the google server via telnet by just sending a request line and a "Host" header... They don't seem strangely picky about requiring headers. Re: URLDownloadToFile is making me mad Big Art18-Apr-03 5:55 Big Art 18-Apr-03 5:55  I don't know what is wrong but I tried to get the data using the Internet API functions: InternetOpen(..)

Re: Link Errors Chris Losinger17-Apr-03 9:40 Chris Losinger 17-Apr-03 9:40  looks like the lib and the app are using different C runtime libraries. look at Project / Settings / General / Microsoft Foundation Classes for both projects - make sure they are the same. -c Chris Losinger Smaller Animals Software File open dialog - ansi vs unicode Richard O.17-Apr-03 9:25 Richard O. 17-Apr-03 9:25  File and directory names are Unicode strings and many (most) non-MS apps don't handle them properly. The Unicode version of openfile dialog can handle 32K characters for a path name while the ANSI version does ~260. This is a good reason alone to always use the Unicode version. Another is if someone uses a non-European language for a directory name. My question is how can this be done and still have the app work on Win98/ME ? If an MFC app is built with the Unicode setting on, does one need to install the "Unicode layer" dll's onto a Win98/ME machine? I thought that I checked and MFC, even when set to Unicode, still limits paths to MAX_PATH. Is there a standard solution? Is there any advantage in making just the file handling portion of the code wide character?
