Ariel28-Feb-01 19:26 Ariel 28-Feb-01 19:26  Hi there All, I'm trying to Retrive the Date in form of COleDateTime from a CMonthCalCtrl and CDateTimeCtrl but not very succesfull at this. I'm trying to Use the BOOL GetCurSel( COleDateTime& refDateTime ) const; function but then i get an invalid Date - i tried to catch different Messages of the Above Controls and none of them do the Job. Can somone please Help me, Just a short Code example to see how its done will be more than enough. Thanks in advance, Ariel. Re: How to Get the Date Value from CMonthCalCtrl and CDateTimeCtrl ? 1-Mar-01 10:01 1-Mar-01 10:01  GetCurSel uses MCM_GETCURSEL which doesn't fill in the time members in the SYSTEMTIME stucture. SYSTEMTIME tSysTime; m_uiCalendar.GetCurSel(&tSysTime); tSysTime.wHour = 0; tSysTime.wMinute = 0; tSysTime.wSecond = 0; tSysTime.wMilliseconds = 0; COleDateTime dtDate(tSysTime); Step through the code or search for _AfxOleDateFromTm in the source to see where the COleDateTime is set to invalid. COM , MFC and Timer 28-Feb-01 18:28 28-Feb-01 18:28  In my COM object with MFC support I want to install a timer: ::SetTimer(NULL, TIMER_ID, 1000, (TIMERPROC)TimerProc); Then I declare MyTimerProc() in COM class as: VOID CALLBACK TimerProc( HWND hwnd, // handle to window for timer messages UINT message, // WM_TIMER message UINT idTimer, // timer identifier DWORD dwTime) ; // current system time and define as: VOID CALLBACK TimerProc( HWND hwnd, // handle to window for timer messages UINT message, // WM_TIMER message UINT idTimer, // timer identifier DWORD dwTime) // current system time { // Do something } But I've got a compiler error: error C2440: 'type cast' : cannot convert from '' to 'void (__stdcall *)(struct HWND__ *,unsigned int,unsigned int,unsigned long)' None of the functions with this name in scope match the target type What am I doing wrong ? Re: COM , MFC and Timer Tim Deveaux1-Mar-01 4:34 Tim Deveaux 1-Mar-01 4:34  typedef VOID (CALLBACK* TIMERPROC)(HWND, UINT, UINT, DWORD); is defined in WINUSER.H. It looks like it depends on whether STRICT is defined - take a look at the WINUSER.H header. If not, TIMERPROC is defined to nothing, which is what the compiler is complaining about. If defining STRICT causes probs, you might try just using the straight cast. Of course, its early in the morning, and I might be missing something... timers in COM objects... hmmm... how to get compressed data length? 28-Feb-01 15:38 28-Feb-01 15:38  I use ICOpen to open a video compress driver, and ICCompressBegin to start to compress data, and ICCompress to encode data; but from ICCompress, I can't get the compressed data length. I think each of the compressed video frame are different size. using ICCompressGetSize? I always get the same value. Some one can help me?

I am using following code in InitDialog for subclassing, but doesn't work . CHeaderCtrl * l_Ctrl = m_List.GetHeaderCtrl(); BOOL l = m_Header.SubclassDlgItem(0,l_Ctrl->FromHandle(l_Ctrl->m_hWnd)); How shld I do it ? Basically, the ida for subclassing is to change the color of Header control of a Report type of ListControl. Thank you , in advance http://sachdevs.tripod.com Re: How to Subclass this control in a Dialog ? 28-Feb-01 23:39 28-Feb-01 23:39  in my code i see this m_BitmapWidth.SubclassDlgItem(IDC_LAYERDLL_LPP_STATIC_BMP_WIDTH, this); where this is dialog and my IDC is not 0 maybe this helps you t! MDI Child Windows, and Docking Toolbars Jamie Nordmeyer28-Feb-01 9:46 Jamie Nordmeyer 28-Feb-01 9:46  Hello all. I have two questions. First, I have an MDI application written without MFC (using strictly Win32 SDK). The children will maximize fine, but once they've been maximized, they won't restore, minimize, or close. Is there a flag that I need to set, or a message that I need to catch to get the child windows to respond appropriately? Second, do any of you know of any good examples of creating a docking control bar using only the Win32 SDK (i.e. no MFC)? Thanks in advance, Jamie. Jamie Nordmeyer Portland, Oregon, USA Re: MDI Child Windows, and Docking Toolbars l a u r e n28-Feb-01 9:53 l a u r e n 28-Feb-01 9:53  the first point ... check how u are maximizing it ... if it wont even close maybe you goofed up some flags second point ... sheesh ... make life hard why dont u ... best thing i could think of is to look thru the mfc source code and see how they did it or fake it using a modeless dialog sorry cant be of more help "every year we invent better idiot proof systems and every year they invent better idiots" Re: MDI Child Windows, and Docking Toolbars Jamie Nordmeyer28-Feb-01 9:58 Jamie Nordmeyer 28-Feb-01 9:58  First, I love your quote. Having been in a customer service position before my present position (I installed and maintained semi-conductor equipment before), this quote exemplifies life pretty well! Second, the reason I'm not using MFC for my app is not to make life harder, but more to understand what's going on behind the scenes. This is a personal project, so there are no time limits (well, I suppose it ought to finished in the next 50 years or so, or I might be dead...). Just more of a curiosity then anything. Thanks. Jamie Nordmeyer Portland, Oregon, USA Re: MDI Child Windows, and Docking Toolbars l a u r e n28-Feb-01 10:05 l a u r e n 28-Feb-01 10:05  hehe .. the quote comes from bitter experience your curiosity about windows is admirable "every year we invent better idiot proof systems and every year they invent better idiots" write into the Registry ? Ariel28-Feb-01 7:12 Ariel 28-Feb-01 7:12  Hi there, Whats the easies and most efficient way to write into the Registry ? I want to write into HKEY_LOCAL_MACHINE and HKEY_CURRENT_USER keys in which i want to open a new SubFolder(key) under "Software" folder (key) (called : MyKey for instance) and under this folder have some properties of kind : int, and CString. I also want a method to retrive this data and alter it if necessary. How can this be done ? Thank you alot, Ariel. Re: write into the Registry ? Chris Losinger28-Feb-01 8:12 Chris Losinger 28-Feb-01 8:12  there are 5 registry classes here: http://www.codeproject.com/system/ -c ------------------------------ Smaller Animals Software, Inc. http://www.smalleranimals.com Re: write into the Registry ? Ariel28-Feb-01 19:46 Ariel 28-Feb-01 19:46  Excellent Reference - Thank you very much for the Answer !!! Re: write into the Registry ? 28-Feb-01 19:10 28-Feb-01 19:10  I wrote a simple class to do with registry. You should contact me. Re: write into the Registry ? Ariel28-Feb-01 19:48 Ariel 28-Feb-01 19:48  Well first i found some wrapper calsses for the Registry handling but i'm always open to new and improved ones. Hope you can show me the headers or all the class code throw a reply or simply by mail. Thank you for the time, Ariel. Some MFC Process Checking ??? Ariel28-Feb-01 7:07 Ariel 28-Feb-01 7:07  Hi there, Some MFC Process Checking : 1. How can i check if a process is running in the same machine already ? (I mean i want to run the same process/App. only once in the machine - how can i check if the process is already running on the machine ?) 2. How can i do the same to check if the process is running in the network ? (I have a Lan Network of Lan and i want to check if the process/App. is already running on one of the machines (pc) is this possible ?) Thank you alot, Ariel. Re: Some MFC Process Checking ??? l a u r e n28-Feb-01 10:01 l a u r e n 28-Feb-01 10:01  use EnumProcesses to get a list of running processes and look for the one you are interested in to detect on a network machine i would build a small messaging system into the app that responds to a ping on a specified port ... as the app starts up try pinging the port on each machine and see if you get response ... if not u night be able to assume it isnt running ... security allowing and all "every year we invent better idiot proof systems and every year they invent better idiots" Re: Some MFC Process Checking ??? Ariel28-Feb-01 19:42 Ariel 28-Feb-01 19:42  Hi there, Firstly, Thank you very much for the answer. I would like 2 ask 2 more favours if you can : 1. Can you show me a small example of the EnumProcesses - how to catch the processes ? 2. On a Network if i'm actually running all the processes on a disk of one machine (which means i access \\AnotherComp\c\APP\MyApp.exe and thats the only place where the source is. Does this change the answer you gave for Network pinging ? Can you explain a bit more about it ? (Code headers will be apritiated here too) Thanks again for your answer, Ariel.
