Thanks, Bye ! Braulio Re: How can I know the margins for a page... Tim Deveaux4-Jan-02 8:42 Tim Deveaux 4-Jan-02 8:42  There's an MSDN article that might be helpful - "HOWTO: How to Use a Program to Calculate Print Margins" - looks like you need to use GetDeviceCaps with PHYSICALOFFSETX and PHYSICALOFFSETY. There's some other stuff here as well. calling a ocx into vc++ xxx3-Jan-02 22:46 xxx 3-Jan-02 22:46  Can anyone help me please? How to call an ocx control(designed in vb) in a vc++ programme? Re: calling a ocx into vc++ 4-Jan-02 1:13 4-Jan-02 1:13  Make sure that your OCX is registered. In the VC++ IDE, with your project loaded, goto Project->Add to Project->Components and Controls. Select Registered ActiveX Controls. Find your control and click Insert. The IDE will make a class to wrap your control. Use this class to create an instance and then call into the methods.

Re: what syntax is this? hex3-Jan-02 19:46 hex 3-Jan-02 19:46  i dont understand the " throw() ",does it break the definition of the function GetInterfacePtr()? thanks Re: what syntax is this? Michael Dunn3-Jan-02 19:58 Michael Dunn 3-Jan-02 19:58  Ah, ok, that indicates to the compiler that the function never throws any exceptions. --Mike-- My really out-of-date homepage Buffy's on.

Re: what syntax is this? hex3-Jan-02 20:11 hex 3-Jan-02 20:11  then if it is "throw (type)" ,what is the meaning ? would you please tell me where i can find the explanation of the syntax ? thanks Re: what syntax is this? markkuk3-Jan-02 23:36 markkuk 3-Jan-02 23:36  It would mean that the function may throw only exceptions of class "type". Look up "exception specification" in some proper C++ reference. Exception specifications aren't supported by VC++6. Re: what syntax is this? Michael Dunn4-Jan-02 8:03 Michael Dunn 4-Jan-02 8:03  markkuk wrote: Exception specifications aren't supported by VC++6. You sure about that? The first hit in MSDN when searching for "exception specification" shows examples of VC code using exception specifications. --Mike-- My really out-of-date homepage Buffy's on. Gotta go, bye!

I found that in the MSDN under Exception Handling Syntax It's a little confuss butc don't said that VC doesn't support Exception specifications... Reagards... Today is Friday!!! and Party!!!

First up How do I determine where to start to map in memory? I am using NT so how do I know how much it is using. And if you can help , how would you go about mapping large files in the first place? Thanks Re: Memory Mapping Philip Patrick4-Jan-02 2:52 Philip Patrick 4-Jan-02 2:52  The functions will tell you exactly where the mapping starts. Use CreateFileMapping() to create a mapping to file and MapViewOfFile() to load a portion (or all file) into memory. The last function will return you LPBYTE, points to the start of mapping Look for descriptions of the functions in MSDN.
