Re: link with one of the multithreaded C run-time libraries. jmkhael10-Dec-03 2:06 jmkhael 10-Dec-03 2:06  Check CreateThread and link with kernel32.lib Papa while (TRUE) Papa.WillLove ( Bebe ) ; Re: link with one of the multithreaded C run-time libraries. Mike Dimmick10-Dec-03 2:38 Mike Dimmick 10-Dec-03 2:38  CreateThread should largely be avoided on the desktop, because it doesn't allow the C/C++ run-time libraries to set themselves up for the new thread correctly. Better to use _beginthreadex and one of the the multi-threaded CRT versions. Note that the single-threaded versions of the CRT aren't thread-safe anyway; you can do your program a fair amount of damage if you try to use the single-threaded version from multiple threads. On Windows CE devices, use CreateThread, because the system entry points and the C run-time are all in coredll.dll - the system is C run-time aware. You can't use _beginthread or _beginthreadex anyway, because they're not there.

Three of them decide to fly off. How many are left? Re: Undo/Redo help required... David Crow10-Dec-03 3:30 David Crow 10-Dec-03 3:30  One way that I've seen it done is to keep a list of each changed document. In other words, each time the document is changed, a copy is kept in a list. When an undo is requested, the latest document in the list is "copied" over the current document, and the view is notified to do a redraw. This is very simplistic but I think you get the general idea. Five birds are sitting on a fence. Three of them decide to fly off. How many are left? Re: Undo/Redo help required... Anonymous10-Dec-03 18:54 Anonymous 10-Dec-03 18:54  step 1. firstly identify the type of operations for which you like to have undo facility. step 2. create a CUndo class and add to it all the necessary variables for each type of opeations. step 3. create a vector of CUndo pointers . step 4 .save all the CUndo object pointers in this particular vector. always save the previous state of the image when the user performs certain action. for example if the image is changed from state1 to state2 then create an undo object storing all necessary information of state1 and add to vector. if the user clicks undo menu then again create an undo object of state 2. then read the last object in the vector, refresh the image with the information retrieved from vector, delete this state1 undo object from the vector, and add the state 2 undo object information. any one used CxImage???? satadru10-Dec-03 0:47 satadru 10-Dec-03 0:47  hi people if anyone has implemented Davide Pizzolato's CxImage class to load images of different formats ...kindly reply to me ... Thanking you Satadru Re: any one used CxImage???? gri10-Dec-03 3:37 gri 10-Dec-03 3:37  is it worth answering this?

CreateRemoteThread under 98 ktvije9-Dec-03 22:39 ktvije 9-Dec-03 22:39  I have a cmd.exe which is executing a .bat file under 98/Me.

All these Example are using create process method for console Application which is created by their own program(output) not interacting with external application. But in my case batch file process(cmd.exe) is created by some one else. Now I know only the ProcessID and ThreadID. From this information I need to go inside the process and get the command line arguments.

Property page trouble pranavamhari9-Dec-03 21:37 pranavamhari 9-Dec-03 21:37  hi, I perform a lengthy operation in a property page when users clicks a button. For example, like this ////////////// m_bUserAbort = FALSE; while(1) { MSG msg; while (::PeekMessage(&msg, NULL, 0, 0, PM_NOREMOVE)) AfxGetThread()->PumpMessage(); if(m_bUserAbort) break; } /////////// However, the dialog is not responding to user's cancel button click, which sets m_bUserAbort to true. what is wrong ? the page is not even responding to move operation by mouse. regards hari Hari Krishnan
