Re: HELP Nish Nishant23-Nov-01 21:22 Nish Nishant 23-Nov-01 21:22  Iterate through the Recordset and keep writing into a flat file. You may write it as XML or as CSV.

Means you can't query them using SQL-like syntax. You'd need to read the records sequentially or using an index. The advantage with an XML file is that you can use XML parsers like Expat or MSXML parser. The advantage with a csv file is the ability to convert it into excel. I think MS has ODBC drivers for CSV files.

Communication with other apps! Ashman23-Nov-01 20:57 Ashman 23-Nov-01 20:57  Hi, I have a question Ive seen programs where a user has a program open like MSN which has edit controls. Another program that isnt made by the same people as MSN is open and it can be used to fill in edit controls like the text field and send messages etc.... How would I do this? Thanks Ashman Re: Communication with other apps! Nish Nishant23-Nov-01 21:13 Nish Nishant 23-Nov-01 21:13  I am not sure I understand you correctly.

I've created a thread that waits for some input (in this case from a socket) and then tries to add this data to the RichEdit box. I am getting an assert error and I have no idea why. Could anyone help me? The code I'm using is thus: char msg[MAXMSGLEN]; while (fConnected) { sock.Recv(msg, MAXMSGLEN); UpdateData(true); t_Display.Format("%s%s\r\n", (LPCSTR)t_Display, msg); UpdateData(false); } - X 'Reality is the only obstacle to happiness' Re: RichEdit member variable woes Michael Dunn23-Nov-01 20:22 Michael Dunn 23-Nov-01 20:22  I assume the UpdateData() call is asserting. You can't pass or access CWnd objects between threads. You'll need to use API-level code to update the edit control from your secondary thread. --Mike-- http://home.inreach.com/mdunn/ While I can't be correct on all matters, I can make the reassuring claim that where I am inaccurate, I am at least definitively inaccurate. your with and Sonork - 100.10414 AcidHelm Browse Direcrtory meirav23-Nov-01 9:30 meirav 23-Nov-01 9:30  How can i open a dialog for browsing a directory ( not a file) ???

Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Questions about CRichEditCtrl squizz23-Nov-01 7:47 squizz 23-Nov-01 7:47  Hi ! I'm developping a small SDI app with a CRicheditCtrlView. a few questions : 1. How can I know that the embedded CRichEditCtrl is scrolling ? I can handle clicks on scroll bars with VK_VSCROLL, handle page up /page down keys .... Is there a way to detect scrolling without coding a method for each message ? 2. How can I calculate the number of text lines being deisplayed ? Is there an equivalent for GetFirstVisibleLine() to find the last visible line ? If not, does someone know a method to achieve this ? Thx Re: Questions about CRichEditCtrl Bill Wilson23-Nov-01 10:09 Bill Wilson 23-Nov-01 10:09  "1. I can handle clicks on scroll bars with VK_VSCROLL, handle page up /page down keys .... Is there a way to detect scrolling without coding a method for each message ?" Override OnHScroll and OnVScroll, these methods are called whenever horizontal or vertical scrolling happens. "2. How can I calculate the number of text lines being deisplayed ? Is there an equivalent for GetFirstVisibleLine() to find the last visible line ? If not, does someone know a method to achieve this ?" I think you have to use GetFirstVisibleLine and then start adding line heights until you get to the window size and declare that your "last visisble line" Hope this helps, Bill XAudio SDK... Joshua Guy23-Nov-01 6:39 Joshua Guy 23-Nov-01 6:39  A while back I had been working on a mp3 player/organizer that used the XAudio engine for playback. I haven't touched it in a while and just recently I wanted to pick it back up, but the xaudio web site has been saying that they are down updating their site. I have been watching it for over a month and either they are very slow at updating or it may not be available for good. Does anyone know where I can download the XAudio SDK(I hope) or does anyone recommend a different solution. Joshua Sonork ID: 100.9944 ICQ: 519642 Hotmail: JoshuaJGuy@hotmail.com Re: XAudio SDK...

Oz Value of a pointer of function Chen Jiadong23-Nov-01 5:00 Chen Jiadong 23-Nov-01 5:00  Hi, all. Below is a program i wrote for test. it contains a class named CBase. #include <stdio.h> class CBase{ public: virtual void VFunction() { printf("Hello, VFunction.\n"); } int _a; }; int main() { CBase obj; int** ppv; ppv = (int**)&obj; void (*pFunc)(); // Now i want pFunc to be assigned to the value of **ppv, // but it can't be like pFunc = **ppv, right? return 0; } so, what can i do for that? Thanks. Re: Value of a pointer of function Michael Dunn23-Nov-01 8:04 Michael Dunn 23-Nov-01 8:04  What are you trying to test? The code doesn't make any sense. Once you do ppv = (int**)&obj;, nothing involving ppv will work right because &obj is not of type int**. The cast forces the assignment to compile, but trying to dereference ppv will cause all sorts of havoc. --Mike-- http://home.inreach.com/mdunn/ While I can't be correct on all matters, I can make the reassuring claim that where I am inaccurate, I am at least definitively inaccurate. your with and Sonork - 100.10414 AcidHelm Re: Value of a pointer of function Chen Jiadong23-Nov-01 18:34 Chen Jiadong 23-Nov-01 18:34  since ppv=(int**)&obj;, ppv point to the begin of obj object, cos' the obj contains a virtual function, it contains a virtual ptr(__vptr), and i'm using vc6, the microsoft complier set the vptr at the begin of the object, so ppv is pointed to the vptr when finishing the assignment. The memory just like below: ---------- | vptr | ---------- |int _a | ---------- CBase obj; (each column is 4 bytes) Re: Value of a pointer of function Michael Dunn23-Nov-01 20:36 Michael Dunn 23-Nov-01 20:36  I still don't understand what you're trying to test. --Mike-- http://home.inreach.com/mdunn/ While I can't be correct on all matters, I can make the reassuring claim that where I am inaccurate, I am at least definitively inaccurate. your with and Sonork - 100.10414 AcidHelm Re: Value of a pointer of function Nish Nishant23-Nov-01 21:00 Nish Nishant 23-Nov-01 21:00  Michael Dunn wrote: I still don't understand what you're trying to test.

Re: Value of a pointer of function Michael Dunn24-Nov-01 8:59 Michael Dunn 24-Nov-01 8:59  That's not how you call virtual functions. You use a pointer to a C++ object, and call methods thru that pointer. class CBase { public: virtual void VFunction() { printf("Hello, VFunction.\n"); } int _a; }; int main() { CBase obj, *pobj = &obj; pobj->VFunction(); } However none of this makes a difference because without a hierarchy of derived classes, you're not using polymorphism, which is what virtual functions are for. --Mike-- http://home.inreach.com/mdunn/ While I can't be correct on all matters, I can make the reassuring claim that where I am inaccurate, I am at least definitively inaccurate. your with and Sonork - 100.10414 AcidHelm
