As I am receiving "Floating point division by zero" exception when using TWebBrowser and TEmbeddedWB from time to time, I discovered that I need to mask division by zero exceptions Set8087CW or SetMXCSR. Q1: What would be the best approach to do this: to mask such exceptions early in the application startup and never touch them again (the app is multithreaded)? to use OnBeforeNavigate and OnDocumentComplete events to mask / unmask exceptions? (is there a chance that exception could occur after the document is loaded?) Q2: What would be the best "command" to mask only "division by zero" and

Is there any documentation on cross thread communication in Delphi? How can I send message to the thread that doesn't have a window? mghie You can only send (Windows) messages to threads that implement a standard message loop, which will automatically be created once a window handle is realized. It is however not necessary to use messages to communicate with a thread. Just let it wait on an event object (TEvent in VCL), and signal this event when you want the thread to perform a function. But if you are new to multi-threading - don't go into all these details on your own, unless you want to

Delphi 2007 (and newer) supports enabling DEP and ASLR via any of these three techniques: add the command-line switch –dynamicbase when compiling with dcc32 add the preprocessor command {$DYNAMICBASE ON} to the source code manually OR in the bit in the header, with {$SETPEOPTFLAGS $40} in the source code I'd like to be able to do the same thing with Delphi 2006 and C++ Builder 2006 (aka BDS 2006). Does anyone know how to do this? Set PE flags You can use {$SetPEOptFlags $40} to set the DEP flag, and {$SetPEOptFlags $100} to set the ASLR flag. To set both use {$SetPEOptFlags $140} . If you have

Suddenly, out of the blue, I get the LME288 linker error.

I just downloaded VS 2013 Community Edition and I wrote my first app. When I run it it shows in the output section: 'ConsoleApplication1.exe' (Win32): Loaded 'C:\Users\Toshiba\Documents\Visual Studio 2013\Projects\ConsoleApplication1\Debug\ConsoleApplication1.exe'.

I am trying to find the simplest way to rotate and display a TBitmap on its center by any given angle needed. The TBitmap is square and any clipping that might occur is not important so long as the rotated bitmap's center point remains constant. The image is very small, only around 50 x 50 pixels so speed isn't an issue. Here is the code I have so far which rotates a TBitmap to 90 degrees, which is simple, the any angle thing less so. std::auto_ptr<Graphics::TBitmap> bitmap1(new Graphics::TBitmap); std::auto_ptr<Graphics::TBitmap> bitmap2(new Graphics::TBitmap); bitmap1->LoadFromFile("c:
