dll example problem Kuniva1-Dec-01 8:32 Kuniva 1-Dec-01 8:32  I am trying to get the hang of programming dll's. 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? Thank You LP Re: Hyperlink on a dialog Michael Dunn1-Dec-01 7:48 Michael Dunn 1-Dec-01 7:48  There's an MFC hyperlink class here. WTL has its own CHyperLink too. --Mike-- http://home.inreach.com/mdunn/ While I can't be correct on all matters, I can make the reassuring claim that where I am inaccurate, I am at least definitively inaccurate. your with and Sonork - 100.10414 AcidHelm Test out a prerelease build of my Hotfix Checker v2.0!

What's the code neccesary for it? Re: Using parameters in a MFC app Michael P Butler1-Dec-01 6:44 Michael P Butler 1-Dec-01 6:44  Look up CWinApp::ParseCommandLine on MSDN. 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!

Dialog Title text Ashman1-Dec-01 0:47 Ashman 1-Dec-01 0:47  How do I set the title bar text on a dialog application...I used to know, and now I have forgotten something as simple as that. SetTitle doesnt seem to work. I want it so if I click on a button it will set the window text to what I specify! Thanks Ashman Re: Dialog Title text User 66581-Dec-01 1:45 User 6658 1-Dec-01 1:45  What about SetWindowText? regards modified 12-Sep-18 21:01pm. Re: Dialog Title text Tim Smith1-Dec-01 4:31 Tim Smith 1-Dec-01 4:31  Or to be more specific. SetWindowText (hDlg, _T ("Test me now baby")); Or if you are using MFC: dlg .SetWindowText (_T ("X")); or SetWindowText (_T ("X")); if you are invoking SWT from an instance of the class.

You can just select the MDAC merge module in the corresponding option, and install shield takes care of the rest. The downside is your installation increases in size. Cheers Kannan Trying to capture and print the screen. GD30-Nov-01 14:50 GD 30-Nov-01 14:50  Hi Folks, I am trying to print a captured screen. In one of the previous posts, it was suggested that a screen can be captured very easily using the code attached below. The code returns a handle to the screen. Does anyone know if and how we can use this handle to print the screen to the printer. Any help is greatly appreciated. Thanks. Gautam code for capturing screen: - HDC hdcSrc,hdcMem; int cx,cy; HBITMAP hBitMap; HWND hwnd; //Get Desktop Handler hwnd = ::GetDesktopWindow(); hdcSrc = ::GetDCEx(hwnd,NULL,NULL); hdcMem = CreateCompatibleDC(hdcSrc); cx = GetSystemMetrics(SM_CXSCREEN); cy = GetSystemMetrics(SM_CYSCREEN); hBitMap = CreateCompatibleBitmap(hdcSrc,cx,cy); SelectObject(hdcMem,hBitMap); BitBlt(hdcMem,0,0,bitmap->bmWidth,bitmap->bmHeight,hdcSrc,0,0,SRCCOPY); DeleteDC(hdcMem); ::ReleaseDC(hwnd,hdcSrc); Re: Trying to capture and print the screen.

Rick York30-Nov-01 17:56 Rick York 30-Nov-01 17:56  Try to get an HDC to the printer and call StretchBlt passing it the HDC and the handle to the bitmap. The other args will define the size you want to display the image. Richedit2.dll / Richedit32.dll Nnamdi Onyeyiri30-Nov-01 12:42 Nnamdi Onyeyiri 30-Nov-01 12:42  Ive seen some pretty good things, like web addresses automaticall turning into hyperlinks using these classes, but i dont have the slitest idea how to use them, all i know is that i need to derive from CRicheditView. PLEASE PLEASE PLEASE htlp me if you can. Thanks. ================================================== The Eclypse Re: Richedit2.dll / Richedit32.dll Henry Jacobs1-Dec-01 4:54 Henry Jacobs 1-Dec-01 4:54  Use riched20.dll. Send the rich edit control the message EM_AUTOURLDETECT. Whenever the user clicks on a link a WM_NOTIFY message will be sent. The notification is EN_LINK. lParam is a pointer to a ENLINK structure containing information about the link. I'm not familiar with MFC's implimentation (ON_NOTIFY(EN_LINK, OnLinkNotification) or something). I hope that helps though.
