Re: Resolving NetBIOS name for IP address Alexander M.,15-Jan-04 5:27 Alexander M., 15-Jan-04 5:27  i tried gethostbyname and it first querries a DNS server, if failed it scans for netbios! don't use slogans like this again please! ---Ranger--- wrote: PS Don't tell me about gethostbyaddr() .

Re: Resolving NetBIOS name for IP address ---Ranger---15-Jan-04 17:45 ---Ranger--- 15-Jan-04 17:45  1. gehostbyaddr() too slowly for LAN (resolving timeout is too big) 2. Name rsolved by gethostaddr can be both DNS or NetBIOS. I need ONLY NetBIOS names ---Ranger--- AVI buffers Member 52521914-Jan-04 23:23 Member 525219 14-Jan-04 23:23  Does someone knows how the buffers of an AVI file are written in the file ? I already search the Microsoft and google sites and I just can't find, maybe for incompetence. If some one knows or knows were can I find this information I will be greatfull. Thanks Re: AVI buffers Abhishek Srivastava14-Jan-04 23:38 Abhishek Srivastava 14-Jan-04 23:38  >Does someone knows how the buffers of an AVI file are written in the file ? please make clear , what do u mean by buffers of an AVI file are written in a file r u trying to read an AVI file , writing its data in some other file. or if u mean how to write AVI file? if the case is later the there is a library available Vfw32.lib. using AVI function of this libray you can create ur own AVI file by writing AUDIO/VIDEO data in it. like 0 AVIFileInit // for initializing AVI library 1 AVIFileOpen // for creating AVI File 2 AVIStreamCreate / for creating Audio/ video stream 3 AVIStreamWrite //for writing audio video data 5 AVIFileClose // for closing ur file 4 AVIFileExit / un initializing the library Abhishek Srivastava Software Engineer (VC++) India ,Noida Mobile no 9891492921 Re: AVI buffers Member 52521915-Jan-04 1:00 Member 525219 15-Jan-04 1:00  I have tryed this functions, but I had a problem that is, I am trying to add one audio stream and one or more video streams, when I join one audio with one video this vfw functions works fine, when I try to join one audio with two videos the videos became scramble, it interleaves the video frames Can you help me with that ? Large Text Display in a Dialog Dov Sherman14-Jan-04 22:56 Dov Sherman 14-Jan-04 22:56  I need to display a long block of scrollable text in a dialog. I tried using a read-only CEdit but it doesn't seem to allow more than ~65000 characters. Is there a way to increase the amount of text a CEdit can display? Or is there a different, more appropriate solution? Re: Large Text Display in a Dialog jhwurmbach14-Jan-04 23:11 jhwurmbach 14-Jan-04 23:11  A CRichEdit can handle almost any amount of text. Just remember to call AfxInitRichEdit before trying to display the dialog. Who is 'General Failure'? And why is he reading my harddisk?!? Loading Bitmap Image sweep12314-Jan-04 22:45 sweep123 14-Jan-04 22:45  I am trying to place a high resolution bitmap on a Picture control. I resize the image to fit on the picture control. However I lose some resolution (its quite bad). I did try and load the image as a jpg and gif and wmf but keep getting the error: c:\Task_Emu\Task_Emu.rc(339): error RC2170 : bitmap file res\PrimaryFlight.gif is not in 3.00 format I have looked at the properties of the Picture control and Bitmap (set to True colour). Are they antthing I can do to get the bitmap (or jpg) displayed a bit better. I expect some lose of resolution, but just want it a bit better if possible Regards, Sweep123. Re: Loading Bitmap Image LunaticFringe15-Jan-04 6:14 LunaticFringe 15-Jan-04 6:14  How much are you resizing it? Re: Loading Bitmap Image sweep12315-Jan-04 6:22 sweep123 15-Jan-04 6:22  Quite a bit! The original image was done in CoralDraw and converted to bmp format (size ~2.MB). Other programs, Paint, PaintShopPro display the detail, its just the Picture control seems to break it up a bit. All I want was a bit more detail if possible. Does that help? Re: Loading Bitmap Image LunaticFringe15-Jan-04 11:01 LunaticFringe 15-Jan-04 11:01  I'm not sure this will help, but you could try StretchBlt'ing the image to a DIBSection in RAM and displaying that. Network connection problem Stan the man14-Jan-04 22:43 Stan the man 14-Jan-04 22:43  Hi. My question is how does a server knows if the connection is suddenly gone for example if the hardware connection is broken? Usually a server will send alive messages etc to the client so the client will know. But how does a server know if that side is gone when it is not shutdown "gracefully?" Is there a function call to help with this? Thanks in advance. Re: Network connection problem Alexander M.,15-Jan-04 5:29 Alexander M., 15-Jan-04 5:29  i suppose there will be "ping, pong" packets to ensure the client is still alive! Don't try it, just do it! Re: Network connection problem Anonymous17-Jan-04 15:41 Anonymous 17-Jan-04 15:41  If TCP connection goes down, your implementation will notice you (FD_CLOSE). But the timeouts are very long if e.g. the network cable was just disconnected, you prolly want to test on your own. How to get a https file FerrariDMan14-Jan-04 22:22 FerrariDMan 14-Jan-04 22:22  Hi Can anybody help me? I have a https-file on a server in the internet and want to get the file. The adress look like: https://ss004.ak.se/http://ss005.ak...productLogo.gif This is not the right adress is only a example. I managed to get a CInternetSession pointer and with that I made a GetHttpConnection to get a pointer to CHttpConnection. With that pointer I know I need to make a OpenRequest() but from that point on I have no clue what to write next. What do I have to do for that??? Thanks D Re: How to get a https file Abhishek Srivastava14-Jan-04 22:37 Abhishek Srivastava 14-Jan-04 22:37  Hi , i have also done the same thing once but using Wininet APIS i can guide u how to use them. To use the HTTP WinInet functions Call the InternetOpen function to initialize an Internet handle. InternetOpen creates the root HINTERNET handle used to establish the HTTP session. The HINTERNET is used by all subsequent functions. Call InternetConnect using the HINTERNET returned by InternetOpen to create an HTTP session. When calling InternetConnect, specify INTERNET_DEFAULT_HTTP for the nServerPort parameter and INTERNET_SERVICE_HTTP for the dwService parameter. InternetConnect uses the handle returned by InternetOpen to create a specific HTTP session. InternetConnect initializes an HTTP session for the specified site, using the arguments passed to it and creates HINTERNET that is a branch off the root handle. InternetConnect does not attempt to access or establish a connection to the specified site. Call HttpOpenRequest to open an HTTP request handle. HttpOpenRequest uses the handle created by InternetConnect to establish a connection to the specified site. Call HttpSendRequest using the handle created by the HttpOpenRequest to send an HTTP request to the HTTP server. Call InternetReadFile to download data. –Or– Call InternetQueryDataAvailable to query how much data is available to be read by a subsequent call to InternetReadFile. Call InternetCloseHandle to close the handle created by HttpOpenRequest. Call InternetCloseHandle to close the HTTP session created by InternetConnect. Call InternetCloseHandle to close the handle created by InternetOpen. in this way u can download ur file Abhishek Srivastava Software Engineer (VC++) India ,Noida Mobile no 9891492921 Re: How to get a https file Marcello16-Jan-04 8:29 Marcello 16-Jan-04 8:29  I did that too but it works only with http files if I am not wrong. It doesn't work with https web pages ! The problem is how to handle the SSL. How can that be done in C++ ? Especially if it is a page that need a login Thank you very much for any answer ! Marcello Re: How to get a https file alex.barylski14-Jan-04 22:49 alex.barylski 14-Jan-04 22:49  You could maybe use URLDownloadToCacheFile.

I have a control derived from CWnd and I create an instance of it on a dialog. The problem is that the control does not get the keyboard focus when I click on it. What am I missing ? Thanks. PS:I work with VC 5. Re: Focus problem alex.barylski14-Jan-04 21:49 alex.barylski 14-Jan-04 21:49  I dunno, theres alot you could have done if your control is derived from CWnd. Maybe make sure that your control inside your dialog resource has tab stop checked? The word of the day is legs, let's go back to my house and spread the word Re: Focus problem Prakash Nadar14-Jan-04 23:14 Prakash Nadar 14-Jan-04 23:14  did you create the control with enabled bit set. I Touched Osama Bin Ladens Bushy Beard CListBox with Checkboxes Cedric Moonen14-Jan-04 21:28 Cedric Moonen 14-Jan-04 21:28  Hello ! I want to have a check box in front of each data in the list box that enable the user to select the datas he wants. Is this functionnality in the CListBox or do I need to subclass the control ? Thanks Re: CListBox with Checkboxes kliviu14-Jan-04 21:39 kliviu 14-Jan-04 21:39  Try to use CListCtrl instead. In Report View it can handle check box-es on the first column automatically. Set extented style to LVS_EX_CHECKBOXES. Re: CListBox with Checkboxes Cedric Moonen14-Jan-04 21:51 Cedric Moonen 14-Jan-04 21:51  Ok, thanks I'll try this Re: CListBox with Checkboxes Antti Keskinen14-Jan-04 21:47 Antti Keskinen 14-Jan-04 21:47  A CListBox is a list of string items. That having said, if you want to have check box buttons instead of string items, then the best way would be to derive a new class from the CListBox and override the DrawItem member function. This function is safe to use: by selecting a certain type of return value, you can tell Windows what type of drawing you did. For example, if draw it completely yourself, then windows doesn't need to draw it anymore. If you don't want to draw a particular cell, you can let Windows do it. Here is a CodeProject link to help you get started: Michael Dunn's article[^] -Antti Keskinen ---------------------------------------------- The definition of impossible is strictly dependant on what we think is possible.
