use CStdioFile class abudu25-Dec-03 20:54 abudu 25-Dec-03 20:54  hi! u use CStdioFile which is a derived class of CFile. this class has BOOL ReadString(CString str) ; function, which reads one line per call. u can refer them in MSDN. This should certainly help u. Similarly u have WriteString also, which writes one line each time. i think File size was already answered. CString class has so many functions which will be useful for u to find some delimiter and many other operations... when going gets tough the tough gets going Problem How to get All files from a Folder xxtra25-Dec-03 8:53 xxtra 25-Dec-03 8:53  Hi Buddies Please Tell me is there API or any Class which can get all files from a Folder ???.

Progress Bar Slowing Down Program shultas25-Dec-03 5:30 shultas 25-Dec-03 5:30  Hello all. I am just playing around with Visual C++ 6.0 lately. I have simple code right now and all it does is read a 350K text file (with fgets) and looks for certain strings in that file and adds them to a listbox. I noticed that when I run the program (without a progressbar) it takes about ~1 second to complete. However, as soon as I implement the progressbar, it takes about 3 seconds to complete for a non-smooth bar, and about 10 seconds to complete for a smooth bar. I've tried two methods of updating the progressbar. The first was I just use SetPos() so I tried using SetStep() and StepIt(). Both of these methods dramatically slow the program down. If I take comment out the SetPos()/StepIt() methods and run the program again, it is blazing fast. I am wondering if anyone knows how I can somehow speed up this process or maybe I am doing something wrong which is causing it to run slower, or is that just the nature of using a progress bar? I really want to have a progressbar in there for the bigger files that I am going to read, just because it looks cool. But in my program, it will eventually read 100's of files and parse through them, so the 5 seconds here and there will really matter. Any ideas on how to speed this up would be appreciated! Shultas Re: Progress Bar Slowing Down Program PJ Arends25-Dec-03 9:21 PJ Arends 25-Dec-03 9:21  Any drawing that is done on the screen will slow a program down, so I would think the best way to speed the program up is to update the progress bar less often, step it every 100K instead of every 10K so your 350K file would only redraw the progress bar 4 times instead of 36 times.

Re: Progress Bar Slowing Down Program shultas25-Dec-03 12:34 shultas 25-Dec-03 12:34  In all honesty, at first I thought that this method would make the progress bar look somewhat "choppy", but I gave it a try anyways. PERFECT results! I did a check of how many times the While() loop was getting executed. Over 39,000 times. So I guess you could say that 39,000 calls to the SetPos would indeed slow the program down .... I just put a lil helper variable in there and called it every 2,000 passes and it blazes perfectly fast just like it did when there was no progress bar at all. Thanks very much for your help. Just a dumb little thing like that I spent a solid hour trying to figure out what the problem was! I guess if you call SetPos(1000) ... SetPos(1500) ... SetPos(2000), out of 39000 tries, between 1000-1300 is the same bar (meaning the progress bar never gets updated to add another bar to it between those numbers), but when you call SetPos() it appears that it still takes some processor time (even though the bar never physically changes). Thanks again!

SetPos() eventually calls SendMessage() which results in a call to the progress bar's window procedure, which handles the message and undoubtedly calls RedrawWindow(), which results in a WM_PAINT being sent to the progress bar, which again calls the progress bar's window procedure, which then does various GDI calls to do the painting. So yes, all that does take CPU time. --Mike-- Ericahist | CP SearchBar v2.0.2 | Homepage | 1ClickPicGrabber New v2.0! | RightClick-Encrypt Laugh it up, fuzzball. how solve this debug erro？ benben25-Dec-03 3:56 benben 25-Dec-03 3:56  Hi: When I build the dll(created by others),VC says: fatal error C1189: #error : Please use the /MD switch for _AFXDLL builds，where to set this flag?

The program should create at runtime a logfile in its folder. When I run the program as normal user without admin-rights, the program can't save the logfile, cause the normal-user has no rights to this folder. Can I do something in the installation-routine, to give the program the right to save files, anyway which rights the user has, who start the prog? Thanks for help! Merry Christmas & Happy new Year!

I created an UnManaged C++ dll in Visual7 then added the C# assmbly with the #using Keyword. in the UnManaged C++ dll I created some functions, which access the objects exported by the C# assembly. the unmanaged C++ dll can be loaded by a nativ C++ Programm and access the C# Objects through the exported functions from the dll. the only bad thing is, that the C# assembly must be in the App Directory or somewhere Windows searches for a DLL.
