As someone says, never trust your inputs - that's the first reason, second reason is, that this will hardcode the _MAX_PATH to your buffers forever. And now it might be that these 260 chars is enough, but will it be enough next year? recommended reading andyblack14-Jan-03 13:14 andyblack 14-Jan-03 13:14  Hi, I am currently undertaking a project a requires the development of a Windows based application. I have some experiance in C++ coding but up to now all the programs I have coded have been command prompt run applications. Just wondering if anyone knew of any good books that would get me started in learning how to program Windows applications. I have looked but there seems a vast amount out there. I am thinking I would rather use the MFC libarys rather than making direct calls to the Windows API itself. Good idea?? Any recommendations would be greatly appreciated Thanks in advance Re: recommended reading carrie14-Jan-03 23:25 carrie 14-Jan-03 23:25  Without MFC http://www.amazon.co.uk/exec/obidos/ASIN/157231995X/ref=sr_aps_books_1_1/202-2181440-5510268 With MFC http://www.amazon.co.uk/exec/obidos/ASIN/1572316950/ref=pd_sim_b_dp/202-2181440-5510268 Two of the best programming books for Windows as far as I know.

I'm using Depends but it shows a bunch of DLLs, such as Kernel or GDI and others. Some of them are probably already on the user's system but what I need to know if which one to include and where to install them (directly in the installation path or system32) ???

Also msvcrtXXX.dll. If you have any C++ that touches the Standard Library, then you will probably need msvcpp60.dll (I am assuming you are using VC6, and the STL that comes with it, if you are using STLPort's STL then use their lib) For other stuff, you'll have top track that down. For example if you are using DirectShow in your app, then there are redistribs with that (don't know what they are). Likewise for other stuff like ADO, et al... ¡El diablo está en mis pantalones! ¡Mire, mire! Real Mentats use only 100% pure, unfooled around with Sapho Juice(tm)!

Be warned that I do NOT have VC7 and have not used it, so there could be other issues, different libs, etc. With ATL 3, depending on how you built your project, you also had to distribute the ATL.dll and there was a different version for Win9x OS vs. NT OS. Don't know if this is still the case. ¡El diablo está en mis pantalones! ¡Mire, mire! Real Mentats use only 100% pure, unfooled around with Sapho Juice(tm)!

My article on a reference-counted smart pointer that supports polymorphic objects and raw pointers modified 29-Aug-18 21:01pm. accessing selected text in a fore ground window Gene Yu14-Jan-03 11:10 Gene Yu 14-Jan-03 11:10  Can any one tell me how to get to the selected text in an edit/richedit control (or any control having text that could be highlighted) of a foreground window from my own application? What about accessing a selected text in IE browser? One can see such use in Microsoft Boolshelf -- highlight any word in any window and then click on the QuickShelf icon in the system tray to get the meaning of the word! Tomasz Sowinski in the VC++ message board mentioned earlier using a combination of (1) calling the WIN32 API GETFOREGROUNDWINDOW to get a handle to the window and (2) sending the EM_GETSEL window message to get a pointer to the selected text. But I am not sure if this limits only to the case when the foreground window is itself a edit/richedit control. Would appreciate very much any answers to these questions!

I am not sure whether this will work or not. but i guess it should. cheers..

Chris Losinger14-Jan-03 10:15 Chris Losinger 14-Jan-03 10:15  use GetTextExtent or DrawTextEx with the DT_CALCRECT flag to find the size of the text. then draw a rect of the appropriate size at the appropriate place. that's a rectangular border. if you actually want an outline around the individual characters (like you might find in a graphics package), then you're in for some work. one way is to draw it slightly larger in black, then draw normal size on top - one character at a time. or, you could draw the text, use some kind of filter to detect the border, overlay the images, etc.. -c I'm not the droid you're looking for. ThumbNailer Re: How do I draw a border around text? clintsinger14-Jan-03 11:27 clintsinger 14-Jan-03 11:27  Could I draw the whole string slightly larger than one I overlay or do I have to do the characters one at a time? Cheers, Clint Re: How do I draw a border around text? Chris Losinger14-Jan-03 12:24 Chris Losinger 14-Jan-03 12:24  if you draw the whole string, you could run into alignment problems, since the spacing between characters may be different between the two font sizes. but, it might be worth a shot. -c I'm not the droid you're looking for. ThumbNailer Re: How do I draw a border around text? benjymous14-Jan-03 23:02 benjymous 14-Jan-03 23:02  One fairly easy solution is just to draw your text 4 times in black, offset by one pixel in each direction, then once in your desired colour in the middle i.e. Text( x-1,y, "Hello", BLACK ) Text( x+1,y, "Hello", BLACK ) Text( x,y-1, "Hello", BLACK ) Text( x,y+1, "Hello", BLACK ) Text( x,y, "Hello", WHITE ) or you could just use a for loop if you want a thicker border Obviously this all relies on your text rendering code being nice and fast, but if you're using anything modern then it should be -- Help me!
