Re: Using variable argument lists Bill Wilson4-Dec-01 9:53 Bill Wilson 4-Dec-01 9:53  Here's an example from the MFC CString class. void AFX_CDECL CString::Format(LPCTSTR lpszFormat, ...) { ASSERT(AfxIsValidString(lpszFormat)); va_list argList; va_start(argList, lpszFormat); FormatV(lpszFormat, argList); va_end(argList); } look up va_list and va_arg in MSDN for more info.

When each button click, my computer call IE window. I want to give a indication in saved cookie. The indication is a meaning to come from my computer. how to?--; please give a courage. Re: How to give a indication in cookie's information Bill Wilson4-Dec-01 9:23 Bill Wilson 4-Dec-01 9:23  To send cookies, you need to add them to the header of your http request. I got this from MSDN: Cookie Header The Cookie header is included with any http requests that have a cookie whose domain and path match the request. The Cookie header has the following format: Cookie: <name>=<value> [;<name>=<value>]... One or more string sequences, using the format <name><value>, contain the information that was set in the cookie. You would use it like this: header = "Cookie: Button1:state1;Button:state2"; then include the header in your Navigate call.

Bernhard3-Dec-01 21:00 Bernhard 3-Dec-01 21:00  i have got two scrollviews on my dialog. (used them as two scrollcontrols.. but don't mind that..) the fact is that they are both intended to work together -> the one shows the headlines, the other one shows the data (something like a report generator). My question now was how to link these two scrollviews, that the user can scroll either of them, and the other one would scroll too... another question would be (but this is not really important) how to hide the scrollbar of the upper scrollview.. is there anybody having an approach for this ? thank in advance and have a nice day Bernhard "There are three roads to ruin: women, gambling and technicians.

Explanation ----------- if i fix the property at design time (More Extended Style) "Right to lfet layout" then it works fine, it changes the layout of all controls, even CTreeCtrl, but if i chnage this property at run time by calling CWnd::ModifyStyleEx(0,WS_EX_LAYOUTRTL);then it changes only title bar and no effect on other controls.

I am recording some data in real-time (voice). Now I need to allow the user for searching for some data given a specific time. I was told that I should consider using SQL, or DAO or ODBC. I have no clue what the best thing to use is. So I am looking for some information. Any suggestion will be largely appreciated. Thanks a lot. Where there is a WISH, there is a WILL. Re: ideas please Bill Wilson4-Dec-01 9:31 Bill Wilson 4-Dec-01 9:31  This isn't a complete solution, but should help you get started. 1. First you need establish the database requirements. e.g. exactly what do you need to store, search, retrieve from your DB. How big are the images, how many, etc. 2. With that in hand, select a database engine. There are many, each has its own strengths, weaknesses and costs. Oracle and SQL server are enterprise databases. They are beefy and very capabley (expensive). Access is good for smaller or simpliler applications. May others also exist. 3. Create the actual database schema (you don't need to populate it, just define it). 4. Finally ready to start designing/coding the app. At this point you can select accessing technologies. The main ones available are ODBC, DAO, ADO. ADO is the current favorite. If this is a significant application, you may want to consult a DB expert to help you design your database and select a db engine.

The main ones available are ODBC, DAO, ADO. ADO is the current favorite. I read a little about these technologies. I am more thinking about using ODBC.

I read that ODBC is more efficient in this case. >If this is a significant application, you may want to consult a DB expert to help you design your database and select a db engine.

Re: ideas please Bill Wilson6-Dec-01 5:38 Bill Wilson 6-Dec-01 5:38  "QUESTION: Are these free? or do I have to by something?" No not free. "This really is a significant application. I am used to get things done by reading, asking questions, prototyping, ... Do you think that these are things we can't learn on the fly ?" No, they aren't. You can, with considerable effort, become a novice DB developer. To go beyond that requires education/experience. If this application is commercial or even IT production, you will be doing yourself a favor to get a professional involved. If it turns out to not be very complicated, it won't cost much. Hope this helps, Bill Re: ideas please Djibril6-Dec-01 11:15 Djibril 6-Dec-01 11:15  Ok. You helped me a lot. That's just too bad you don't accept credit cards I thank you again. Actually, I am a software engineer with 5 years experience in programming realtime systems. I also used to be an analyst-programmer (Dbase IV) for 2 years. But things changed since then. Just to say that I have some notions in programming. After reading your suggestions, I think that I'll implement my own database (binary file with my own format). I only have one thread writing informations to the database while another thread have a read-only access to this database. Take care. Where there is a WISH, there is a WILL.

Wait, I think the selection of a database is the least of your worries! Do you really want to store 1 second clips ?? In order to play a 10 second piece, you have to retrieve 10 1-sec clips using SQL SELECT, squish them together (how?), then play the 10 sec clip. It is quite a challenge in compressed formats like MP3. It may be simple in WAV but note that WAV is an uncompressed format. It will eat up your storage in no time. I dont know the background of your project, but it sounds like (no pun intended ) a streaming input with a non-streaming output system. I suggest you store incoming stream in 1-2 hr chunks of compressed format, such as MP3. Then use a player such as Winamp to skip to a location. CMemDC Christopher Lord3-Dec-01 17:40 Christopher Lord 3-Dec-01 17:40  I am having a problem with this class. I've noticed there are a couple, so here is the comment at the top so that we know which one i'm using (edited for space): // CMemDC - memory DC // Author: Keith Rule // Email: keithr@europa.com // Copyright 1996-1999, Keith Rule Now, my problem. I have a program which has its own skin format. I was having some flicker problems when updating some text on top of the skin, and tried various fixes. When I found this class, I thought my problems where solved. Lately, I've been having crashes on screen resolution changes. Specifically an access violation (0x...05). I figured it was my code and have been diffing and whatnot for the past few days. Turns out, its this class! If I use normal drawing calls, the problem goes away completely. Has anyone had similar problems with this class? If so, how did you fix it? Or is there a better version out there? Re: CMemDC Rick York3-Dec-01 18:45 Rick York 3-Dec-01 18:45  I use this class extensively with no problems. Does your CMemDC object exist for the lifetime of the display window ? If so that is not how it is typically used. Usually it exists only while the WM_PAINT message is being handled which is in OnDraw for MFC apps. The demo program that comes with it illustrates this. Re: CMemDC Christopher Lord3-Dec-01 18:49 Christopher Lord 3-Dec-01 18:49  I've managed to manifest my problem without CMemDC so it is my code thats causing it. It seems it's related to my drawing code.
