help! sunmozhou11-Jul-04 16:28 sunmozhou 11-Jul-04 16:28  I don't know the meaning of the following sentence: the "WinMain" function is the begining of the Windows application ,it create the windows which receive the message and enter the message circulation. Does this function create the main window of the application? Re: help! Ryan Binns11-Jul-04 17:53 Ryan Binns 11-Jul-04 17:53  WinMain() is the function that Windows calls when it starts your program. Typically, this is where you create the main window and implement a message loop so you can process messages.

Does this function create the main window of the application? Yeah if use CreateWindow() function to craete a window. ShowWindow() to Make the Window Visible. and GetMessage() and DispatchMessage() to handle messages. ----------------------------- "I Think It will Work" ----------------------------- Alok Gupta visit me at http://www.thisisalok.tk String = File || Directory? Timothy Grabrian11-Jul-04 16:05 Timothy Grabrian 11-Jul-04 16:05  How can I tell if a string is a file or a directory? Can I do it without searching the string myself looking for a period?

Kuphryn Re: String = File || Directory? Michael Dunn11-Jul-04 19:56 Michael Dunn 11-Jul-04 19:56  PathFileExists() will tell you if a file system object exists with a given name. If that returns true, PathIsDirectory() will tell you if it's a directory. --Mike-- Personal stuff:: Ericahist | Homepage Shareware stuff:: 1ClickPicGrabber | RightClick-Encrypt CP stuff:: CP SearchBar v2.0.2 | C++ Forum FAQ ---- I even hear the Windows "OMG I booted up fine" sound.   -- Paul Watson diagnosing hardware problems. Re: String = File || Directory? Anonymous11-Jul-04 23:42 Anonymous 11-Jul-04 23:42  Use the CRT _stat function, see in MSDN, notice the _stat::st_mode: Bit mask for file-mode information. The _S_IFDIR bit is set if path specifies a directory; the _S_IFREG bit is set if path specifies an ordinary file or a device. User read/write bits are set according to the file's permission mode; user execute bits are set according to the filename extension. Multiline listbox alesha11-Jul-04 14:22 alesha 11-Jul-04 14:22  Guys I would really appreciate if somebody gives me any ideas for the following task: I need to have a control on a dialog to insert text there that would be able to have an image at the beginning of every message and also would be able to associate a data with every message. Also, if a message is too long to fit the entire text within the control's borders, the text must be wrapped. I mean broken into lines. ListBox came to my mind first. You can insert images and accociate a data with each item. But ListBox is not a multiline control. I found some projects on Codeguru and Codeproject for multiline listbox controls but they don't work as they are supposed to be. I need an urgent advice. Thanks a lot! Re: Multiline listbox Ryan Binns11-Jul-04 17:59 Ryan Binns 11-Jul-04 17:59  You could try an owner-draw list box or list view control...

You'll have to use polling. A Knight of Islam wrote: also i want to know if i can stop the interrupt to the Microprocessor while i'm using the parallel Port Only by writing a device driver. But be very careful. As soon as you do disable interrupts, everything in the system will grind to a halt until you reenable them.

I want to detect a clock from another computer, i want to send data from one port to another, when data is there, one of the bits in the status register in the receiving computer will be changed by the sending computer, i want to get the data on the port when this register bit is high I want to send a sequence of data from one computer to another through parallel port as an experiment to apply it on a wireless device (setting registers, clocking, and detect clocking to receive data) I want to detect the change to see if there's new data or no.. About the Interrupt I know that that system will stop doing anything while interrupt, is there some C++ codes or tools used to stop the interrup to the computer by anyother device?! Thank you for Your Help very much Ryan Re: Checking Parallel Port Status Ryan Binns12-Jul-04 18:13 Ryan Binns 12-Jul-04 18:13  A Knight of Islam wrote: one of the bits in the status register in the receiving computer will be changed by the sending computer, i want to get the data on the port when this register bit is high So read the status register repeatedly until the bit is high, and then read the data port. A Knight of Islam wrote: I want to send a sequence of data from one computer to another through parallel port as an experiment to apply it on a wireless device I'm not sure what the problem is here... Send the first byte, then the second, then the third etc... Or am I totally missing the point? A Knight of Islam wrote: is there some C++ codes or tools used to stop the interrup to the computer by anyother device?! To disable a interrupt from a device, you have to disable the CPU's interrupt handling, unless you want to reprogram the interrupt controller chip - not a fun thing to do. I've done this before, but many years ago so I can't remember how and don't have access to my information. Google should help though.
