VC7 MDE SHTML Syntax Coloring Jason Hooper24-Apr-02 4:06 Jason Hooper 24-Apr-02 4:06  In the VC6 IDE it was simply Alt-Enter, Down arrow to HTML. I haven't been able to figure out yet how to ask the VC7 MDE to color .shtml files.

Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk? How to express empty? Feng Qin24-Apr-02 3:29 Feng Qin 24-Apr-02 3:29  In BNF statement, there is a symbol can express "empty" meaning. But I don't know how to express "empty" meaning in YACC decription file? I'm amumu, and you? Re: How to express empty? Joaquín M López Muñoz24-Apr-02 4:13 Joaquín M López Muñoz 24-Apr-02 4:13  I'd say it is more or less like this: emptyrule : ; but I could be totally wrong Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Using CProgressCtrl (an idiot asks...) 24-Apr-02 3:24 24-Apr-02 3:24  Hi, I am pretty new to VC++, I mainly use it to create small dialog-based apps using the Windows API. However, at the moment I am trying to create a progress bar using the CProgressCtrl with a window created using CreateWindowEX() (I don't want to use the normal CreateWindow...PROGRESS_CLASS method for the bar as I want to use an extended class that can create a progress bar with gradient colours). This sounds stupid, but I am completely stumped on how to create a progress bar this way. My problem seems to lie with the difference between CWnd and HWND. The parent window that I want to use for the control is not a dialog, but has been created using CreateWindowEx(), and I can't find any examples on the net of how to do this properly (all the examples I can find relate to dialog-based apps). This is the code I am trying to use: CProgressCtrl MyProgressBar; CWnd *parentwindow = CWnd::FromHandlePermanent(hwnd); //hwnd = windows window created using CreateWindowEx()... MyProgressBar.Create(WS_VISIBLE|WS_CHILD|PBS_SMOOTH,CRect(10,10,200,30),parentwindow,1); This is all in WinMain(). Everything compiles okay, but when I run the executable I get an assertion error (line 19 of afxwin1.inl, or some such) and of course, there is no sign of the progress bar. If anyone could tell me what I am doing wrong (and I know it's something really stupid owing to the fact that I'm a novice programmer), I would be very grateful. Many thanks, Keith Re: Using CProgressCtrl (an idiot asks...) Joaquín M López Muñoz24-Apr-02 3:31 Joaquín M López Muñoz 24-Apr-02 3:31  This is all in WinMain() I guess this is where the problem lies. If you're dong raw Win32 apps (which provide of a WinMain) you've got no MFC support. CProgressCtrl is an MFC class, so it's on wonder nothing works. Create a new project and select the "MFC app" type (or something like that.) The way of writing programs changes from what you're used to, but it doesn't take long to get a passing idea of how it works. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: Using CProgressCtrl (an idiot asks...) 24-Apr-02 11:03 24-Apr-02 11:03  Hi, thanks for your reply. I've got my program set up so that it's using "MFC in a shared DLL", and there I no errors when I compile. Is it the case that you can't use MFC and WinAPI together? Sorry for the dumb question, but I've never used MFC before. If that's the case I guess I'll have to get learning MFC, unless there is some way of using a gradient coloured control bar in WinAPI (it's the only feature I need to add to my program...). Again, thanks for your help. Cheers, Keith Re: Using CProgressCtrl (an idiot asks...) Ravi Bhavnani24-Apr-02 3:35 Ravi Bhavnani 24-Apr-02 3:35  Keith, imho you're much better off using MFC (as Joaquín suggested). You could then just use this class. /ravi "There is always one more bug..." http://www.ravib.com ravib@ravib.com Re: Using CProgressCtrl (an idiot asks...) 24-Apr-02 11:00 24-Apr-02 11:00  Thanks for your reply. That's actually one of the classes I was looking at using. Looks like I'll have to go away and learn MFC... Thanks again, Keith Drag'n Drop, between applications, to get HWND ?

How to use DLLs Aoife24-Apr-02 1:55 Aoife 24-Apr-02 1:55  Hello, I need to use a dll file (that I downloaded from the net) in my MFC VC++ application, but I am new to dll's and VC++ and don't know where to start. I was hoping that someone knew of a document that I could read that would show me how to do this. Thanks, Aoife Re: How to use DLLs Sameer Maggon24-Apr-02 1:59 Sameer Maggon 24-Apr-02 1:59  What kind of a DLL you have downloaded, and how do you intend to use that.. Re: How to use DLLs Tom Archer24-Apr-02 2:29 Tom Archer 24-Apr-02 2:29  Typically, the DLL is going to come with a header file and an import library. 1) Simply include the header file where you need to - either in the file that will be references any of the DLL's exported types or functions) or in the stdafx.h file 2) Add the import library to the project. 3) Place the DLL in one of the following folders (This is the order windows searches for DLLs) The current folder The Windows folder The Windows system folder The folder where the main application is being run from The folders listed in the PATH environment variable A mapped network folders Let me know if you need any more help.

Re: How to use DLLs Ravi Bhavnani24-Apr-02 7:32 Ravi Bhavnani 24-Apr-02 7:32  If the DLL doesn't come with an import lib, you can get at an exported function by using GetProcAddress(). However, you'll still need a .h file that describes the function's prototype. /ravi "There is always one more bug..." http://www.ravib.com ravib@ravib.com SetSockOpt, NO_DELAY and buffering pmarki24-Apr-02 1:43 pmarki 24-Apr-02 1:43  Hello. I have a problem sending packets at the right time. My app sends a packet (16-100kbytes) each 10 seconds... but they are paired up and received as 2 packets each 20 seconds. I used setsockopt with no_delay set to 1 and it didn't help. My send buffer is 8192 bytes, I use win98 and winsock 1.1 How can I force winsock to send each packet separately ? Any help would be appreciated... Re: SetSockOpt, NO_DELAY and buffering Sameer Maggon24-Apr-02 1:58 Sameer Maggon 24-Apr-02 1:58  Hi, Actually, it might be that the packets are buffered and sent when buffer is full (normal behavior).. So you have to flush the data from the buffer so that it writes the data. Sameer Re: SetSockOpt, NO_DELAY and buffering pmarki24-Apr-02 2:04 pmarki 24-Apr-02 2:04  Yes, that's what I am trying to do... Do you know how to flush the data using windows sockets 1.1 ? I think I should switch to winsock version 2.2, there is a SIO_FLUSH command in WSAIoctl()... anyone used that with positive outcome ? Re: SetSockOpt, NO_DELAY and buffering Joaquín M López Muñoz24-Apr-02 2:21 Joaquín M López Muñoz 24-Apr-02 2:21  Winsock buffers data, but does not wait as long as 10 seconds (by default, it's buffering time, i.e. the time it waits for more data before flushing to the net, is 100 ms.) So I'd say the problem is somewhere else. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: SetSockOpt, NO_DELAY and buffering pmarki24-Apr-02 3:31 pmarki 24-Apr-02 3:31  Yeah, you were right... the problem was one else statement which somehow got commented out and I don't know why... Thanks m8 I was almost ready to switch to w2k ... Application HOOK Sameer Maggon24-Apr-02 1:35 Sameer Maggon 24-Apr-02 1:35  Hi, I've created a DLL and exposed two functions InstallHook and DeleteHook Actually one of my application hooks this dll for getting the application which have started on my computer The problem is that, i am writing all that in a log file (a simple .txt file), but the filename is Hard Coded. How can i make this filename such that, my dialog based application which is actually initiating this DLL pick up this filename. Re: Application HOOK Joaquín M López Muñoz24-Apr-02 2:36 Joaquín M López Muñoz 24-Apr-02 2:36  Pass the filename along as a command line parameter. Read this parameter in your InitInstance using CCommandLineInfo (for example.) Joaquín M López Muñoz Telefónica, Investigación y Desarrollo
