starting help 18-Sep-01 3:01 18-Sep-01 3:01  I have created a help file external to vc++, but i can not figure out how to run it. I have created a message map ON_COMMAND(ID_HELP,OnHelp) I have created a OnHelp function What do i need to put in the OnHelp function to startup the help file? Or am I looking at this from the wrong direction thank you ? Re: starting help Anders Molin18-Sep-01 6:33 Anders Molin 18-Sep-01 6:33  From MSDN: WinHelp Starts Microsoft® Windows® Help (Winhelp.exe) and passes additional data that indicates the nature of the help requested by the application. BOOL WinHelp( HWND hWndMain, LPCTSTR lpszHelp, UINT uCommand, DWORD dwData ); - Anders Money talks, but all mine ever says is "Goodbye!" how to get the method's address in the class? ac952_z_cn18-Sep-01 2:59 ac952_z_cn 18-Sep-01 2:59  In a class,I want to put the method's address to a DWORD value.

Basically I want the Tab Control to fill the entire window at all times. My Code is as follows CRect size; GetClientRect(&size); int iWndWidth = size.right; int iWndHeight = size.bottom; ::SetWindowPos(m_tabs,0,0,0,iWndWidth-15,iWndHeight-15,SWP_NOMOVE | SWP_NOZORDER); Can anyone tell me why i needed to subtract 15. By the way It's a CFormview i am working with. Thanks In Advance Rich Re: Resizing Controls Tomasz Sowinski18-Sep-01 2:28 Tomasz Sowinski 18-Sep-01 2:28  Why are you subtracting 15?

WHAT?" Re: Resizing Controls Tomasz Sowinski18-Sep-01 3:10 Tomasz Sowinski 18-Sep-01 3:10  OK - I will re-phrase my question. What happens when you don't subtract 15? Tomasz Sowinski -- http://www.shooltz.com Re: Resizing Controls Rashid Thadha18-Sep-01 3:43 Rashid Thadha 18-Sep-01 3:43  use void CFormViewEx::OnSize(UINT nType, int cx, int cy) { CFormView::OnSize(nType, cx, cy); if (m_pTabCtrl.m_hWnd != NULL) m_pTabCtrl.MoveWindow(0, 0, cx, cy); } Then you don't have to subtract 15 Re: Resizing Controls AJ12318-Sep-01 23:25 AJ123 18-Sep-01 23:25  That piece of code with the 'movewindow' does the job well. Cheers When i didn't subtract 15, the Tab Control was not drawn in the top left and was therefore too big for the screen. Still curious why that happened, anyone know why? IE arguments sleater18-Sep-01 1:49 sleater 18-Sep-01 1:49  I have several problems with my code you can see here . . . void CProjectSoftwareDlg::OnStart() { if(WinExec("iexplore -k index.html",SW_SHOWNOACTIVATE)>31) { OnOK(); } else { MessageBox("Damn..."); } } . . . . 1. Problem: The ie doesn't even run. I always get "damn" back... 2. Problem: I am not able to set index.html to "index.html" because of those "'s 3. Problem: I have to get a local pathfile into the IE is this possible or do i have to get the filesystem. At all i get no warning or error back while compiling. I hope you are able to help me sleater Re: IE arguments Anders Molin18-Sep-01 2:02 Anders Molin 18-Sep-01 2:02  Use ShellExecute() instead of WinExec() Like ShellExecute(handle, "open", "http://www.codeproject.com/", NULL, NULL, SW_SHOWNORMAL); if you want to open a webpage, or ShellExecute(handle, "open", file:///c:\test.htm, NULL, NULL, SW_SHOWNORMAL); to open a local file... And yes, there are 3 "/" in file:///, it's not a typo Hope it helps... - Anders Money talks, but all mine ever says is "Goodbye!"

Convert centimeter to pixel 18-Sep-01 1:13 18-Sep-01 1:13  Can somebody tell me how I can convert centimeters into pixels? e.g. I have given the value 25cm (centimeters, an european, or at least german unit of measurement ) and want to know the value in pixels. I nee to draw some object very accurate onto the screen. Any code is greatly appreciated regards Re: Convert centimeter to pixel Christian Graus18-Sep-01 1:20 Christian Graus 18-Sep-01 1:20  I'm sorry to inform you that an answer will only be possible if every monitor in the world is the same size and runs the same resolution. You can find out the resolution from Windows, I know of no way to find out the size of the monitor with accuracy, let alone the fact that you can control from the front panel how much of the screen is used.

Re: Convert centimeter to pixel 18-Sep-01 1:26 18-Sep-01 1:26  You probably didn't unerstand my question I.e I just found out that 100 pixel are equal to 3,571 centimeters. Now I need to convert Pixels into Centimeters an vice versa. How can I do this using c++? Re: Convert centimeter to pixel Steen Krogsgaard18-Sep-01 2:18 Steen Krogsgaard 18-Sep-01 2:18  What Chris was trying to make clear was that 100 pixels may equal 3.571 centimeters on your monitor, but on mine it could be 4.672 cm (just an example). How is c++ supposed to know the size of your monitor? And even if it knew it was a 17'' monitor, how is it supposed to know how big the screen's display area has been set to by means of the buttons on the front of the monitor? There are som DC functions you can use to get an *estimate*. Set your mapping mode to one of the fixed-size ones (MM_TWIPS, MM_LOENGLISH, MM_HIENGLISH etc) an use the LPToDP and DPToLP functions. But there's no satisfaction guarantee! Cheers Steen. "To claim that computer games influence children is rediculous.

These calls will return the number of logical pixels per inch. Having this, calculating centimeters into pixels should be easy - just remember that one inch is 2.54 centimeters. Tomasz Sowinski -- http://www.shooltz.com Re: Convert centimeter to pixel 18-Sep-01 7:31 18-Sep-01 7:31  Thanks! I will try this. Erm...I need to get the DeviceContext (DC) from my monitor fist, right? How do I do this?
