Re: Pop3 9-Feb-01 3:58 9-Feb-01 3:58  Either write you own implementation of the protocol (Search for the RFCs on the web). If you want to interface to Microsoft's mail API's, you need to examine the MAPI interface. Good luck. I found the documentation to be, er, less than helpful when dealing with MAPI. Not as good as the rest of the documentation. I think the platform SDK and MSDN have some sample MAPI code. Stephen Kellett Re: Pop3 Rob Caldecott9-Feb-01 4:26 Rob Caldecott 9-Feb-01 4:26  I have a lot of experience here - and you will save a fortune by investing a few hundred dollars into a library such as the Dundas TCP/IP stuff. However, POP3 is a pretty simple protocol, and once you have the RFC, it is quite easy to work it out. There is sample code on this site for sending messages (SMTP) abnd POP3 isn't much different. Simply connect to a server on TCP port 110 and send a few commands. Avoid MAPI like the plague - in many cases, it assumes an MS only environment and is a waste of time. I have been coding mail apps since 1992 and MAPI sucks. Stick to decent Internet standards (POP3/SMTP) and you can't go wrong. Regards. MFC CString Question.... 8-Feb-01 14:38 8-Feb-01 14:38  A starting programmer needs help I turn here for help. Please help me, I am using CString because I am coding for Windows CE. I run my code through Visual Studio to use the console to make sure its working. the aim is to try and cut up a string into many pieces. but I can't even output a simple string.(this saddens me) Example Code: CString hd ("test"); LPCTSTR h = hd; CString *lk; lk = hd; printf("%s", hd); printf("%s", (LPCTSTR)hd); printf("%s", h); cout << h; cout << lk; cout << *lk; My Problem: For the printf function the only thing I get is always the first character 't'; for the cout, I always get the memory location in all cases, so what I am asking is, CAN SOMEONE TELL ME HOW I CAN PRINT OUT THE FULL STRING....PLEASE!!!! thank you lonod To Code or not to code, that is the question MFC CString Question.... 8-Feb-01 14:35 8-Feb-01 14:35  A starting programmer needs help I turn here for help.

Michael Dunn8-Feb-01 14:57 Michael Dunn 8-Feb-01 14:57  printf("%s", hd); This doesn't work because sending a CString to printf() is meaningless. You must cast it to (LPCTSTR). --Mike-- http://home.inreach.com/mdunn/ This must be Thursday. I never could get the hang of Thursdays... Re: MFC CString Question.... efosa8-Feb-01 15:06 efosa 8-Feb-01 15:06  Thanks for quick reply mike, if you notice I did cast it to LPCTSTR in the next printf function, but all i still got was the first character of the string. To Code or not to code, that is the question Re: MFC CString Question.... Michael Dunn8-Feb-01 15:13 Michael Dunn 8-Feb-01 15:13  Ah, it's probably because you're using printf() when you should be using wprintf(). CE is a Unicode OS, so when you pass a Unicode string to printf(), it views the string as an ANSI string. The first byte is 't' and the second byte is 0. Also, use wcout instead of cout, and add (LPCTSTR) casts to your CStrings to make sure they're being passed as C strings instead of C++ objects. --Mike-- http://home.inreach.com/mdunn/ This must be Thursday.

Richard Cheng8-Feb-01 9:18 Richard Cheng 8-Feb-01 9:18  I'm developing a program required to use Synchronization function WaitForSingleObject(). It may take several seconds or longer to run this function, therefore, I want to add a Progress Bar control to let the user knows how long do they need to wait. However, I cannot find the source code of this WaitForSingleObject() function, so I cannot put the progress bar SetPos() in that function. I've tried to set the progress bar move by timer...but when the program run WaitForSingleObject(), the progress bar stopped and start move again after WaitForSingleObject(). Can I do it in this way???:: If originally the timeout value is 16000....(WaitForSingleObject(xxxx, 16000)), then I split it into ... let say....5 ......e.g.: WaitForSingleObject(xxxx, 3200); Call ProgressBarControl; WaitForSingleObject(xxxx, 3200); Call ProgressBarControl; WaitForSingleObject(xxxx, 3200); Call ProgressBarControl; WaitForSingleObject(xxxx, 3200); Call ProgressBarControl; WaitForSingleObject(xxxx, 3200); Call ProgressBarControl; So that the progress bar can update every 3200 time interval?..... Or do anyone have another suggestion on using WaitForSingleObject with Progress Bar?? I must use this WaitForSingleObject function...... Sorry...I just a beginner in MFC programming;P Re: WaitForSingleObject() Question Again!!!! JoeBloggs10-Feb-01 23:37 JoeBloggs 10-Feb-01 23:37  Instead of WaitForSingleObject could you not use MsgWaitForMultipleObject just before the thread is about to do it's stuff create a Timer that fires every second. when MsgWaitForMultipleObjects returns determine what's happened has the thread finished or do you have a windows msg i.e. WM_TIMER. if this is appropriate you could have a class variable that indicates what step the thread is up to - wrapped by a CriticalSection so you can update your UI accordingly. Visual C++ style build log window 8-Feb-01 9:05 8-Feb-01 9:05  How can I create a Microsoft Visual C++ style build log window? Thanks Re: Visual C++ style build log window Michael Dunn8-Feb-01 20:08 Michael Dunn 8-Feb-01 20:08  Check out the BCGControlBar library at BCGSoft (it used to be housed here at CP, but it's been taken down.) --Mike-- http://home.inreach.com/mdunn/ This must be Thursday.

Re: Visual C++ style build log window 9-Feb-01 13:55 9-Feb-01 13:55  I visited the site, and the library seems very good, but what I need is not an EXACT copy of the visual c++ build window. I only need to know how to create a window with an edit control in it, that moves, docks and behaves similar to the one in visual c++. CString to char array[40] Johnny Starr8-Feb-01 8:18 Johnny Starr 8-Feb-01 8:18  I'm kind of new to MFC. I used to using Borland. How can I convert a CString to a char array[40]. To be used as a filename I will open using old style ansi C fopen. Additionally I noticed that in Microsoft VC++ you can not write a int long or double using fstream or iostream. This is pretty Lame. In Borlands compiler you write a double somefile lessthan operator somedouble lessthan operator endl Is there an easier way than using the old ansi style C fprintf to get your double written to a file.

Re: CString to char array[40] Anders Molin8-Feb-01 8:46 Anders Molin 8-Feb-01 8:46  How about: char *s = strdup(LPCTSTR(MyCString)); (don't forget to free s later...) As far as I remember it should work... - Anders Re: CString to char array[40] Michael Dunn8-Feb-01 9:13 Michael Dunn 8-Feb-01 9:13  char array[40]; CString str = "whatever"; lstrcpy ( array, str ); But, if you're just passing the filename to a function - that is, the argument is a const char* - you can just pass the plain CString, since CString has a conversion operator to LPCTSTR. --Mike-- http://home.inreach.com/mdunn/ This must be Thursday.

Re: CString to char array[40] Erik Funkenbusch12-Feb-01 13:26 Erik Funkenbusch 12-Feb-01 13:26  I don't understand your problem. fstreams with ints, doubles, and longs work fine. It sounds like you're using the wrong operators. Please, don't make condescending comments when you don't even understand what you're doing. #include <fstream> int main(void) { std::ofstream s("myfile.txt"); int i = 1; double d = 2.0; long l = 3; s << i << " " << d << " " << l << std::endl; return 0; } CString to char array[40] Johnny Starr8-Feb-01 8:16 Johnny Starr 8-Feb-01 8:16  I'm kind of new to MFC.

Microsoft does not provide a copy constructor for CList. Is there any way or alternatives that i can use beside than CList. I have tried to return a CList from a function but the compiler told me that there is no constructor to copy the list. I dont want to develop my own list because i dont have time for that. STL list is tedious to use and compatibility errors often pop up. So please help. thank you. leonwoo Re: Problem with CList, Carray,.... Daniel Ferguson8-Feb-01 3:48 Daniel Ferguson 8-Feb-01 3:48  Create a CList in the fn that calls this fn, then pass the CList by ref or by a pointer to the fn, then fill the list in the fn. You can return the number of items added to the list as a success/ failure check. Regards, Daniel Re: Problem with CList, Carray,.... leonwoo8-Feb-01 10:55 leonwoo 8-Feb-01 10:55  hi, Thanks for your solution Daniel but i don't understand what it means by fn. Can you please give me an example code so that i can get the whole picture. Thank you leonwoo
