Insight on STL Containers & One Specific Question valikac1-Dec-01 12:53 valikac 1-Dec-01 12:53  Hi, What is your perference when it comes to STL containers? I know many programmers prefer the vector because it random-access. However, deque container is random-access and could be changed from front, middle and back. I prefer the list, but it is hard for me to access specific data inside the list mainly because of my inexperience with STL. Nonetheless, I prefer list because of the innovative way it manages insert and delete (does not need to move all data). I am implementing deque a program. The program reads data from a file line by line. The program saves each line of data from the file into a character array. I want to "push" each character array into a deque. At the end, I use the unique function to delete all clones. For example let say I have a file with the following: ------- 123 231 123 321 ------- First, the program reads one line at a time and copy the line into a character array. Then the program copies the entire character array into the STL container. Once the program has reached the end of the file, then it will delete all clones such as "123" from the above example. How do you push a *character array* into an STL container, specifically a deque? Thanks, Kuphryn Re: Insight on STL Containers & One Specific Question Chris Hafey1-Dec-01 17:08 Chris Hafey 1-Dec-01 17:08  Each container has its place, but I definitely find myself using vector more than anything else. As far as your problem goes, you can use std::string to do what you want, you also might want to consider just using set instead of a deque if you don't care about order (set will automatically remove duplicates). Chris Hafey Re: Insight on STL Containers & One Specific Question Todd Smith2-Dec-01 5:29 Todd Smith 2-Dec-01 5:29  FYI if you reserve() data in a vector it doesn't have to allocate after each new insert until you exceed it's limit. And at that point it usually allocates 2x it's current data size (1000 -> 2000 -> 4000 etc.) std::vector<std::string> data(1000); as for your deque you can use std::deque<std::string> data; ifstream infile("filename); std::string temp; while (!infile.eof()) { infile >> temp; data.push_back(temp); } Todd Smith Re: Insight on STL Containers & One Specific Question valikac3-Dec-01 12:48 valikac 3-Dec-01 12:48  Thanks everyone. I am not familiar with the set container. Can you post a straightforward example of set declaration and insert? Thanks, Kuphryn Finding the keyboard and mouse Winstone1-Dec-01 11:10 Winstone 1-Dec-01 11:10  Using Visual C++ 6, I need to programmatically, discover what type of keyboard (Serial or PS2) is used on a computer, and what type of mouse (serial or PS2) is used. This needs to be done on Windows 95/98/NT/2000 and XP.

Now I find that for Win 2000 the keys are different. For keyboard :- Key - HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\KeyboardClass Query this value - \Device\KeyboardClass0 It will return the registry address to find further info. On my machine I got this - \REGISTRY\MACHINE\SYSTEM\ControlSet001\Services\kbdclass So I opened that key. By the way replace \REGISTRY\MACHINE\ with HKEY_LOCAL_MACHINE Open the Enum subkey Query this value - 0 I got this - ACPI\PNP0303\4&3ec904f&0 So now open this key below :- HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\ACPI\PNP0303\4&3ec904f&0 Now query this value - DeviceDesc That will tell you what your keyboard is. pretty long winded I didnt chk for mouse. But it should be something similar Regards Nish Sonork ID 100.9786 voidmain www.busterboy.org If you don't find me on CP, I'll be at Bob's HungOut Name of Internet Connection ?

I succeeded in compiling an example from the MSDN but the problem is i need to import the dll manually (without a .lib file) but it wont work. Here's the code for the DLL: #include "stdafx.h" extern "C" VOID assimGL() { MessageBox(NULL,"hello world from DLL!","DLL",MB_OK); } here's the code for the test app: #include <stdio.h> #include "stdafx.h" typedef VOID (*MYPROC)(); int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) { // TODO: Place code here. //MessageBox(NULL,"hello","hello",MB_OK); HINSTANCE hinstLib; MYPROC ProcAdd; BOOL fFreeResult, fRunTimeLinkSuccess = FALSE; // Get a handle to the DLL module. hinstLib = LoadLibrary("assimDLL"); // If the handle is valid, try to get the function address. if (hinstLib != NULL) { ProcAdd = (MYPROC) GetProcAddress(hinstLib, "assimGL"); // If the function address is valid, call the function. if (fRunTimeLinkSuccess = (ProcAdd != NULL)) (ProcAdd) (); // Free the DLL module. fFreeResult = FreeLibrary(hinstLib); } if(!fRunTimeLinkSuccess) { MessageBox(NULL,"Link failed!","Failure",MB_OK); } return 0; } Can anyone please tell me whats wrong with it and how it WILL work for sure? Thanks in advance Kuniva Re: dll example problem Rick York1-Dec-01 9:24 Rick York 1-Dec-01 9:24  It appears that assimGL is not exported. It needs to have a __declspec(dllexport) statement in front of it. Have a look at the DLLHUSK sample in MSDN. It illustrates this fairly well. Re: dll example problem Lim Bio Liong3-Dec-01 1:15 Lim Bio Liong 3-Dec-01 1:15  Also take note of the calling convention of the exported DLL function (i.e. __stdcall or __cdecl). This will affect how the function name will appear in the export table of the DLL which will in turn determine whether function GetProcAddress() succeeds. To keep things simple, always add a .DEF file to your DLL project and add a EXPORTS section to it. Then make sure that the function name "assimGL" is listed in this section. For example : LIBRARY assimDLL EXPORTS assimGL Hyperlink on a dialog 1-Dec-01 7:17 1-Dec-01 7:17  I am in need to place a hyperlink on a dialog. In want the user's browser to come up, when the link is clicked (just like a standard hyperlink to a HTM resource). Is there an easy way to do this, or do I have to detect the mouse click, search for the default browser and spawn an instance of it?

Michael Re: Using parameters in a MFC app Simon Walton1-Dec-01 6:52 Simon Walton 1-Dec-01 6:52  You might want to take a look at the CCommandLineInfo structure the appwizard creates for you in InitInstance(). You'll need to override ParseParam() to parse your own paremeters. Then set the necessary flag (perhaps an int) to indicate which form of the program is running. You can then set up your app to behave differently. Simon Hey, it looks like you're writing a letter!
