This updater gets called by the other application called someapp.exe. Updater receives three arguments 1. calling application (full path of someapp.exe) 2. location of the installer file 3. installing destination folder So when someapp.exe calls updater.exe it immediately exits (it will get overwritten). Because this exiting process isn't instant, updater should check if it's still "alive". How can I do this? Can I get some handle from 1st argument and check if application is still running?

Make sure this HANDLE is inheritable and then when you call CreateProcess to create the callee ensure the bInheritHandles argument is set to TRUE. The callee can then call WaitForSingleObject passing in this HANDLE to wait until the caller has exited. Steve convert char* to double and back Andy H12-Aug-07 22:11 Andy H 12-Aug-07 22:11  I have a char* that holds a numeric value of for example: 172,500 and I want to multiply this by another number and write the contents back to a new char*. Could someone give some example code on how to easily achieve this? Re: convert char* to double and back sw@thi12-Aug-07 22:34 sw@thi 12-Aug-07 22:34  You can use atoi and itoa functions to achieve this. atoi - converts string to int. itoa - converts int to string.

What I think I will do is write a class that can cater for all eventualities, as there is also a possibility of the number being in scientific notation, just to make matters worse! Re: convert char* to double and back Nishad S13-Aug-07 1:21 Nishad S 13-Aug-07 1:21  You can do it simple... first filter out the comma. If you are using the CString, use str.Remove(',') so that the comma will be filtered. Then you can convert it to integer using atol, atoi, etc., or _ttol, _ttoi, etc. - NS - how do you package an MFC program king'ori12-Aug-07 20:28 king'ori 12-Aug-07 20:28  hi i am new to MFC and i have a small (my first ) program-sort of schedular program .I want to package it and deploy it to my friends so that they can run 'setup' and install it in their PCs. is it much work to do that and how is it done? thanks in advance Re: how do you package an MFC program Peter Weyzen12-Aug-07 21:02 Peter Weyzen 12-Aug-07 21:02  You want to make an installer.

See my post in CP[^] - NS - Re: DeleteObject Hans Dietrich12-Aug-07 21:57 Hans Dietrich 12-Aug-07 21:57  If you have the GDI object selected into a DC at the time of the DeleteObject(), the object will not be deleted. You must first use SelectObject() to restore the original object, before using DeleteObject(). Best wishes, Hans [CodeProject Forum Guidelines] [How To Ask A Question] [My Articles] Re: DeleteObject Nishad S12-Aug-07 23:13 Nishad S 12-Aug-07 23:13  But this issue is not due to that. Even if we just create a brush and delete it very next, this issue exists. - NS - Re: DeleteObject Mark Salsbery13-Aug-07 4:17 Mark Salsbery 13-Aug-07 4:17  The task manager isn't a debugger. This issue has been around since Windows began.  I still have never seen documentation about what really goes on behind the scenes.  Maybe a certain number of handles are cached. If you find the true answer, please let us all know By the way, if you repeatedly do this and the number of handles keeps increasing then you probably have a leak. You can wrap handles in a class to track leaks or use 3rd-party leak-detection tools if you're worried about it.  Otherwise, make sure you select GDI objects out of DCs and destroy them when you're done Mark Mark Salsbery Microsoft MVP - Visual C++ ;how do you haddle OnAplly() for many property sheets [modified] king'ori12-Aug-07 19:47 king'ori 12-Aug-07 19:47  hi since when Apply is clicked in a property sheet, its OnAplly() calls updateData() for the active page and initializes an ELLPROP structure with the settings, then sends a message to the main window containing the structures address.The main Window forwads the massage to the view (so far so good),the view copies the property values to its own data members (comes the problem) -suppopse i have many property sheets,each one will have an OnApply() that will fill the ELLPROP Structure with its own values, the mainframe will handle OnApply Once like this LRESULT CMainFrame::OnAplly(WPARAM wParam,LPARAM lParam) { m_wndView.SendMessage(WM_USER_APPLY,wParam,lParam); return 0; } then the view also will handle it once ..view::OnAplly(WPARAM wParam,LPARAM lParam) { ELLPROP* pep = (ELLPROP*)lParam; // my question what do i do here (if am supposed to do it only here) if i have multiple property sheets // lemmi give an example i may think of using proprty sheets insead of very many dialog boxes to write a simple school management program. so one property sheet be for registration (first page studets reg, 2nd page staff reg,3rd page, members reg ..), another property sheet will be for finance (1st page setting the fees charges,2nd page payment of fees, 3rd page payment os salaries and wages to workers, 4th page payment of bills ..) know i want each to update a database using ADO so each property page will have to open an appropriate recordset and do that(i havent tried the database part and know whether it will bring problems too),what i have tried is to have all the input values sent to the view so that i can display them in the client area and i dont know how the view's member variables will copy all these values that are coming from different property sheets and each sending an ELLPROP structure..(should i have some kind of control to know that this structure is from the finance sheet so just copy the finance deatils and leave the registration details- and if so how do i control that) ....... ..... } am new to MFC (4 mths know) so please if you can give me more deatils i'll rilly appreciate,thanks. i h -- modified at 2:28 Monday 13th August, 2007 Re: ;how do you haddle OnAplly() for many property sheets prasad_som12-Aug-07 19:56 prasad_som 12-Aug-07 19:56  Can you reword the question, to others understanding ?

This holds true even if your application does not use MFC Doc/View. This paradigma is called model/view/controller and is independent of the toolkit used. You just might have to code more yourself.
