Re: Bitmap in parent overlaps child dialog. aquawicket15-Jun-07 9:57 aquawicket 15-Jun-07 9:57  Good man mark... It was definetly a Z-order issue.. MoveWindow() works it out.. Thank you very very much.. IMPLEMENT_DYNCREATE - passing parameters to constructor Vaclav_14-Jun-07 11:46 Vaclav_ 14-Jun-07 11:46  This IMPLEMENT_DYNCREATE / DECLARE_DYNCREATE pair uses only default, protected and without parameters constructor. The macro uses class name as a paramater. Is there any way to get around this? Thanks for reading Vaclav Re: IMPLEMENT_DYNCREATE - passing parameters to constructor Mark Salsbery14-Jun-07 12:10 Mark Salsbery 14-Jun-07 12:10  Vaclav_Sal wrote: Is there any way to get around this? Yes - implement your own version of the macros There's a few reasons doing this doesn't make sense and/or is impossible: Since the macros help implement a method of creating objects given only a class name, the only possible constructor to use is a default one. If you know enough about the class to know that the constructor takes a parameter then creation by classname wouldn't be necessary. Even if you implemented a different constructor, MFC wouldn't be able to use it. Mark "Posting a VB.NET question in the C++ forum will end in tears." Chris Maunder Question about string in C++ ( simple question i think ) Yanshof14-Jun-07 11:34 Yanshof 14-Jun-07 11:34  Hi, My application gets some information from the command line and need to check if some string include in this command line. I don't know how to check/analyze if some specific string is in this command line - What i mean is if i need to know if the string "abcd" is in the command line - how can i do it ? I can use CString and use the CString method Find(...) - but i don't allow to do so. Is there is other way smart way ? ( some C/C++ method maybe) Thanks. Re: Question about string in C++ ( simple question i think ) Mark Salsbery14-Jun-07 11:58 Mark Salsbery 14-Jun-07 11:58  The strstr()/wcsstr() runtime library function does what CString::Find() does. Is there a specific part you are having trouble with? Mark "Posting a VB.NET question in the C++ forum will end in tears." Chris Maunder Re: Question about string in C++ ( simple question i think ) Rick York14-Jun-07 18:17 Rick York 14-Jun-07 18:17  You can include stdlib.h in your file and then can access __argc and __argv. Alternatively, you can use the MFC way which is CCommandLineInfo. If you look at the implementation of CCommandLineInfo (in appcore.cpp) you will find that it builds up its string using __argc and __targv which is the TCHAR variant of __argv.

CRecordset+ date paulosuckow14-Jun-07 11:24 paulosuckow 14-Jun-07 11:24  Hi Please help me do a query based on date. I have m_pSet (a pointer to CRecordset) and a filter m_strFilter my date is a ColeDateTime in the form of "mm/dd/yyyy" I need to set: m-pSet->m_strFilter to select records with birthday >= 1/1/1970 Any idea.

Both scrollbars are enabled and effective (i.e. there is scrolling amount), working fine. The static control is a subclass of CStatic. I am monitoring the mouse actions in this static control with OnLButtonUp, OnLButtonDown, OnRButtonUp, OnRbuttonDown and OnMouseMove. Additionally, there is an OnMouseMove in the parent window of the static control (which is the dialog). This monitors if the mouse leaves the rectangle of the static control. Everything works fine, EXCEPT when the mouse moves from the static control over the vertical scroll bar rectangle, this will not be reported to the parent's OnMouseMove However, there is no problem with the horizontal scroll bar, and if the vertical scrollbar is disabled, then the mouse move will be reported. What can be the reason to this behaviour? Re: Mouse event pecularity in vertical scrollbar [modified] Mark Salsbery14-Jun-07 10:08 Mark Salsbery 14-Jun-07 10:08  That sounds strange. If the scrollbars are standard scrollbars (not controls) then they are part of the non-client area of the static control. I would expect the wParam of a WM_NCMOUSEMOVE message in the static control then would be HTHSCROLL/HTVSCROLL. *edit* I guess I should clarify - what sounds strange to me is that the parent would get a mousemove message when the cursor is on the scrollbar of a child window... -- modified at 16:15 Thursday 14th June, 2007 "Posting a VB.NET question in the C++ forum will end in tears." Chris Maunder Re: Mouse event pecularity in vertical scrollbar Vancouver14-Jun-07 10:15 Vancouver 14-Jun-07 10:15  The scroll bars are separate controls. I'm sorry, I did not mention this, because I thought the fact that the mouse movement over the horizontal scroll bar will be reported makes this clear. Re: Mouse event pecularity in vertical scrollbar Mark Salsbery14-Jun-07 10:24 Mark Salsbery 14-Jun-07 10:24  In that case, it still sounds strange. I would expect the mousemove messages to go to the scrollbar controls, not the parent Are the scrollbars children of the dialog or the static control? Mark "Posting a VB.NET question in the C++ forum will end in tears." Chris Maunder Re: Mouse event pecularity in vertical scrollbar Vancouver14-Jun-07 11:07 Vancouver 14-Jun-07 11:07  The scrollbars are children of the dialog. Re: Mouse event pecularity in vertical scrollbar Mark Salsbery14-Jun-07 11:23 Mark Salsbery 14-Jun-07 11:23  I can't see where the behavior would be different between the scroll bars. WM_MOUSEMOVE messages go to the window under the cursor. If the cursor is over a scrollbar control then the messages should go to that control.

Chris Maunder Registering COM dll on 64-bit XP rana7414-Jun-07 7:27 rana74 14-Jun-07 7:27  We have a COM dll built on windows 32 bit OS. When this dll is attempted to be registered on a 64 bit platform,we get the following error: INFO: Calling Action w32OcxRegActions10.2.0.1.0 RegisterOCX OcxPath = ..........dll WorkingDir = ...........\bin INFO: Exception thrown from action: RegisterOCX Exception Name: ErrorRegisteringOCXException Exception String: OLE initialization or OCX load error while registering OCX Exception Severity: 0 This dll is registered successfully on a 32 bit platform. Does not a dll built on 32-bit XP(win2k) get registered on a 64-bit XP using regsvr32? two instances of a DLL act_x14-Jun-07 7:06 act_x 14-Jun-07 7:06  I have a DLL which has options to do different tasks based on the options selected during initialization lets call this A.dll so say there is an intialization API AInit( int mode = mode2) // can take mode1 or mode2 Now applications App 1 and App 2 can load this dll but load using different options. I want to prevent this from happenning simultaneously. in other words my requirements is that someone loads A in mode 1 or mode 2 but not simulataneously in mode 1 and mode 2. Additionally i could have multiple users, load A.dll in mode 2 ( multiple readers ) but multiple of Mode 1 or a mix of Mode 1 and Mode 2 should be disallowed. Is there a way I enforce this in code or ideas to do the same ? I was thinking on the lines of a Mutex ! Engineering is the effort ! Re: two instances of a DLL Matthew Faithfull14-Jun-07 8:17 Matthew Faithfull 14-Jun-07 8:17  A Mutex is exactly what you need. Specifically a named Mutex which by being named can therefore be shared between Processes. Nothing is exactly what it seems but everything with seems can be unpicked. Exporting data to mutiple.txt files ciphus2114-Jun-07 6:08 ciphus21 14-Jun-07 6:08  Hello everyone. I currently have a combination program that is spitting out millions of combinations into a single .txt file and i am having issues with the file crashing when it tries to open. I was wondering if there is a way you can set up the program to put like 500k combinations in one file and then create another file untill it runs out of combinations. I am fairly new to C++ and any help would be appricated. I will post my current code later when i get back home from work. Thank you!
