Frankvw5-Apr-02 3:44 Frankvw 5-Apr-02 3:44  I've just written a program with VC++ .Net (My first one with this environment ), and i realise that when I close the window, the process does not close. It makes access to an oracle and a MS access database through MDAC (jet for Access, and ODBC for Oracle) Any clues? Regards, Frank A simple MFC problem 5-Apr-02 3:01 5-Apr-02 3:01  Hi ! I have several databases (in mdb format) for my MFC project. I decided to put them on a server in the network. The path is like this: //netbackup/multimedia/erginasil.mdb The problem is: The server (netbackup)has a password which I have but the users will not have.If I first connect there ,the program runs normally. How can I acces a password protected server in the code. I found in msdn opening a password-protected "file" but I must give the "server password" to connect normally. Thanks in advence.. Re: A simple MFC problem Carlos Antollini5-Apr-02 3:15 Carlos Antollini 5-Apr-02 3:15  You need to connect the resource. See the Network Functions... For example WNetAddConnection Best Regards.

Sonork ID 100.10529 cantollini Character map/Symbol picker Mauritz Bomark5-Apr-02 2:30 Mauritz Bomark 5-Apr-02 2:30  Hi Does anybody know where I can find a symbol/character picker (MFC/C++ source code) where you can choose font and character? I'm looking for something like the character map application (charmap.exe) in Windows. Any suggestion? Thanks in advance. /Mauritz FTP, filetime problem 5-Apr-02 2:06 5-Apr-02 2:06  Hi i'm writing a FTP-client using win32 functions. I need to compare the "ftLastWriteTime" of a file on a ftp server with a file on a local client without downloading the file from the server(s). I can use FtpFindFirstFile and FindFirstFile to retrieve this time. The problem is that FtpFindFirstFile returns the time by the local timezone. How can i convert this time to UTC(zone independent) format?? Thanks Fred CHTMLView and OnNewWindow2 Matt Gullett5-Apr-02 1:51 Matt Gullett 5-Apr-02 1:51  I have written a custom web browser for my company. I wrote it in MFC using the CHtmlView class. Everything is working well except: I handle the OnNewWindow2 method to popup a new window and I have everything working as far as popping up the window, showing/hiding the toolbar, menubar, status bar. The problem is I can't find a way to determine the appropriate size of the new window. The info is not passed in with the call and does not appear to be available through the interface. My best guess (from looking around) is that I need to create an event sink against the WebBrowser object itself and capture the settings there. I am not sure if this is the right approach and I am not quite sure how to go about doing this anyway. Does anyone have any suggestions? Thanks in Advance Matt Gullett Compliter error.... AsnowCn5-Apr-02 1:06 AsnowCn 5-Apr-02 1:06  i create a dialog based program,add some code to add tray icon,popup menu.but when i finished and complite it,1 error occoured. it said the the Dialog ID have been used and can't be overWrite.But where the place is Wizard create code, i never changed it.. so what caused it? Thanks a lot... Re: Compliter error.... Renjith Ramachandran5-Apr-02 8:11 Renjith Ramachandran 5-Apr-02 8:11  sometimes the resource ID wich u created newly is the same as the Dialog Resources ID...jusk look in to the resource file and look up on the Dialods ID..and look on the code u added newly..and change if there any..that will work..try it now..!!!

STL set compare headache _Magnus_5-Apr-02 0:49 _Magnus_ 5-Apr-02 0:49  Im trying to use a set of _bstr_t with a custom compare func. The compare func is defined as this struct _bstr_t_cmp_fn : public std::less<_bstr_t> { bool operator ()(const _bstr_t &r1, const _bstr_t &r2) { return (stricmp(r1, r2) < 0) ? true : false; } }; i then use it like this std::set<_bstr_t, _bstr_t_cmp_fn> oPaths; which works fine, insert seem to work the way it should to, but then i want to use the set::find() function. I defined the iterator like this, no problem std::set<_bstr_t, _bstr_t_cmp_fn>::iterator it; but when i then try this it = oRefs.find(e); // ( e == _bstr_t object ) i get compiler errors error C2662: '()' : cannot convert 'this' pointer from 'const struct _bstr_t_cmp_fn' to 'struct _bstr_t_cmp_fn &' Why is that?? ...it gives me a headache.. /Magnus Re: STL set compare headache Dominik Reichl5-Apr-02 0:58 Dominik Reichl 5-Apr-02 0:58  Hmmm... perhaps it = oRefs.find(&e); works? Re: STL set compare headache _Magnus_5-Apr-02 0:56 _Magnus_ 5-Apr-02 0:56  No does not work, get another error which is what i should get since the set contains _bstr_t and not _bstr_t *. /Magnus Re: STL set compare headache Dominik Reichl5-Apr-02 1:07 Dominik Reichl 5-Apr-02 1:07  And when you simply remove the &s in the bool operator ()(const _bstr_t &r1, const _bstr_t &r2) declaration? Re: STL set compare headache _Magnus_5-Apr-02 1:02 _Magnus_ 5-Apr-02 1:02  nevermind, the () operator have to be bool operator ()(const _bstr_t &r1, const _bstr_t &r2) const Really crappy error msg i think.....but thats STL it seems /Magnus Re: STL set compare headache Michael Dunn5-Apr-02 16:32 Michael Dunn 5-Apr-02 16:32  You have another bug in that stricmp() is the wrong function to use.

Re: STL set compare headache _Magnus_7-Apr-02 22:19 _Magnus_ 7-Apr-02 22:19  I store _bstr_t not BSTR and _bstr_t have a (char *) operator so it should work just fine. (maybe not the most efficient way) /Magnus copying strings in managed code Ignacio Varas4-Apr-02 23:42 Ignacio Varas 4-Apr-02 23:42  hi, My question could be a stupid question, but i don't find the solution. It's simple I have a managed function like that: bool GetValorBinary(LONG lVarId, String & pCadena, int length) - inside code i create a new String, where pcadena2 is a TCHAR. String * prue(pcadena2); - now i want to do something like to back the value in pCadena pCadena=pcadena2; - but at build i recived the next error: error C2582: 'operator =' function is unavailable in 'System::String' Any suggestion? thanks in advance. Salamanca 2002 Capital Cultural Europea, Visitala Re: copying strings in managed code Dominik Reichl5-Apr-02 0:49 Dominik Reichl 5-Apr-02 0:49  Perhaps strcpy(pCadena, pcadena2); helps? Re: copying strings in managed code Ignacio Varas5-Apr-02 2:10 Ignacio Varas 5-Apr-02 2:10  thanks, but not, it doesn't work, i had try yet. anymore ideas?

Re: copying strings in managed code Le centriste5-Apr-02 7:32 Le centriste 5-Apr-02 7:32  First of, are you sure that: String *pru(pcadena2); works? In the System::String class, there is a Copy() function that would do what you want. Michel If I am wrong or said something stupid, I apologize in advance Re: copying strings in managed code Ignacio Varas7-Apr-02 23:18 Ignacio Varas 7-Apr-02 23:18  hi, Yes i'm sure. that's works, but Copy() fuction doesn't works, doesn't generate any errors but not copy the string.

What i'd like to know is why stop there...? Why not make your encryption 134217728bit strength...this would take a millenia on even a cray super computer, which would be pretty hard to beat...Is it because of time required to encrypt/decrypt...? Or is it an actual limitation on the size of data the ciphers can accept...? Just curious... Thanx!
