Connecting people. *** Hook COM Dll called from VBScript tony_cork26-Sep-02 0:20 tony_cork 26-Sep-02 0:20  Hey, I have written an executable to capture mouse/keyboard events and play these back after. The function basically writes the message data to a text file, and reads it back in for playback. I now need to put this into a COM DLL so that I can call it from a VBScript to get a playback. The problem i have is with the ::SetWindowsHookEx function. I call it as follows g_hHoohPlayBack = SetWindowsHookEx(WH_JOURNALPLAYBACK, JournalPlaybackFunc, LoadLibrary((LPCTSTR) "TRShell"), 0); and in the callback JournalPlaybackFunc function, i use this to recreate the mouse/keyboard event PostMessage(HWND_BROADCAST, WM_SERVICE_INFO, SI_S_PB_WAIT, lReturnValue); It seems to be going into the callback function ok, but there is a problem with the Postmessage parameters. This code worked fine for the executable, but not when i use it in a dll and call from VB. Nothing happens. Thanks for any help tony Linker Error ??

Now when i include this file in more than one file including Application.cpp , it gives a linking error for all the functions and structurs -->> function <myfunction> already defined in Application.obj Re: Linker Error ?? Tomasz Sowinski26-Sep-02 0:24 Tomasz Sowinski 26-Sep-02 0:24  You shouldn't add function definitions in .h, only functions declarations (prototypes) and structure types. Split wioctl.h into wioctl.h and wioctl.cpp. Tomasz Sowinski -- http://www.shooltz.com *** Vodka. Connecting people. *** Re: Linker Error ??

Hello World!!! from Raphaël Multiple view in SDI nadra26-Sep-02 0:05 nadra 26-Sep-02 0:05  hi, I have an SDI application. I have a splitter with left and rigth view . I have added a list in left view. Now i want that whenever any of the nodes in left view is clicked, the view in the right change and show some data, if other is clicked some other data is shown And every right view should retain its data . how can i do it ?? thnx, Re: Multiple view in SDI Tomasz Sowinski26-Sep-02 0:22 Tomasz Sowinski 26-Sep-02 0:22  Handle LVN_ITEMCHANGED in left view and change the right view accordingly. What kind of window is the right view? Tomasz Sowinski -- http://www.shooltz.com *** Vodka. Connecting people. *** Re: Multiple view in SDI Roman Fadeyev26-Sep-02 1:41 Roman Fadeyev 26-Sep-02 1:41  You might notify your CDocument about view changing and then inform all views by means of UpdateAllViews (see MSDN). Create some flags in CYourDocument, which describe document state at that moment, when you update views. Each view will look at this flags and will decide whether must it make update of itself or not. Or you can manage updating of views from CYourDocument class and decide here which view needs update. Also you may find specified view by means of GetFirstViewPosition/GetNextView but I do not recommend to link views directly. It is better to use technique described above. ere FTP question Renjith Ramachandran25-Sep-02 23:49 Renjith Ramachandran 25-Sep-02 23:49  friends, i wrote an application to download the files from an FTP server by using the CFtpConnection,CInternetSession and CFtpFileFind... my application will check the ftp server in a time interval,and if there is any files then simply download them..i used this program to collect files in which other users upload to that ftp server i used the GetFile() method to download the file...but my problem is that...if there is any files they are not completley Transfered(transfering in progress),they are also downloads.ie i get some incomplete /damaged files Is there is any way to identify the Files in which they are in the Status of Transfering(copying to server),ie not completely uploaded to the server.... hav any idea..?? A Programmer Never Dies..*** Re: _DEBUG question Tomasz Sowinski26-Sep-02 2:21 Tomasz Sowinski 26-Sep-02 2:21  In the release build, _DEBUG isn't defined. #ifndef _DEBUG evaluates to true at compile time and code is included. ns wrote: Or is there something like _RUN or something that makes code run at runtime thats within #ifdef _RUN execute?

Re: Listbox Steve S25-Sep-02 22:56 Steve S 25-Sep-02 22:56  GetTopIndex() will tell you which is the top visible item. After that, it's not rocket science to figure it out. Steve S [This signature space available for rent] Re: Listbox Steve S26-Sep-02 23:46 Steve S 26-Sep-02 23:46  Just for the rocket scientists out there;P If you know the height of one item (htItem), (LB_GETITEMHEIGHT) and you know the client height of the list (htClient), you can, by dividing htClient by htItem, determine the number of visible items. If you then know the top index, you can also work out the bottom index. To make items become visible programmatically, you can scroll the list by calling SetTopIndex (in MFC, message is LB_SETTOPINDEX) appropriately. If you resize the list box, you have to recalculate, of course Steve S [This signature space available for rent] Create Dialog Anonymous25-Sep-02 22:44 Anonymous 25-Sep-02 22:44  I'm migrating from VC++ 6.0 to VS.net.

Raphael Kindt25-Sep-02 21:51 Raphael Kindt 25-Sep-02 21:51  Hello world. Can anybody tell me what's the difference between those MACRO in MFC: ASSERT( booleanExpression ) and: VERIFY( booleanExpression ) I know what they mean but I don't see any difference... Thanks in advance... Hello World!!! from Raphaël Re: The difference between VERIFIY() and ASSERT()... Steve S25-Sep-02 21:58 Steve S 25-Sep-02 21:58  Unless AdamUK beats me to it again... ASSERT disappears in a release build, while VERIFY doesn't. For example, ASSERT( ( p = somefunction() ) != 0) VERIFY( ( p = somefunction() ) != 0) In the first case, the code is =eliminated= and will more than likely cause some hapless (or should that be witless) developer to tear out their hair trying to figure what's gone wrong. In the second case, the code is retained, but no test is actually performed. At least, that's how they used to work...

Mazdak25-Sep-02 21:29 Mazdak 25-Sep-02 21:29  if (remaining & pAccess->dwValue) { remaining &= ~pAccess->dwValue; // DoSomething(pAccess->szName); } remaining is a typedef DWORD structure and pAccess is a structure and dwValue is DWORD type. What does one & mean?And what does its next line means?:remaining &= ~pAccess->dwValue; Mazy "If I go crazy then will you still Call me Superman If I’m alive and well, will you be There holding my hand I’ll keep you by my side with My superhuman might Kryptonite"Kryptonite-3 Doors Down Re: Can somebody explain these lines for me? adamUK25-Sep-02 21:45 adamUK 25-Sep-02 21:45  Mazy, The & operator is the bitwise 'AND' operator. Your code takes dwValue and performs a bitwise and operation with remaining. Eg if remaining = 0000101011 and dwValue = 0100011001 then the result is 0000001001 (in binary) If the if statement is nonzero, it executes the remaining code. x&=y is equivalent to x=x & y (the bitwise operator again) ~ is the bitwise ones complement (or NOT operator) i.e. 010101 becomes 101010 in binary. So, remaining &=~pAccess->dwValue is equivalent to remaining=remaining & ~pAccess->dwValue Hence the bits in dwValue are complemented (ie. all the 1s turn to 0s and the 0s turn to 1s) it is then 'AND'ed with remaining and the result stored in remaining.
