Not familiar with Win32, If you can, add something like the following: BOOL MyDialog::PreTranslateMessage(MSG* pMsg) { // catch any WM_USER messages if (pMsg->message == WM_USER) { // see if it's your message if (pMsg->wParam == LB_ADDSTRING) { ... process the message .... .....

check the video driver settings on both machines. my guess is that one is using 16 bit color. Cleek | Image Toolkits | Thumbnail maker

That was the problem. Thanks.

CreateURLMoniker returns S_OK. The only reason I know that it is failing at the specific line is that the HRESULT returned by ShowHTMLDialog != S_OK (I have tested all other return values). I guess the most important question from here is to find what error code exactly the function returns. That is what I can't find documentation on. Thanks for the help.

So, you should set a breakpoint and step through the offending code. Or check the stack trace to see where the call has come from. Christian I have several lifelong friends that are New Yorkers but I have always gravitated toward the weirdo's. - Richard Stringer

Yep, I was overwriting...thanks for pointing out my stupid mistakes ;P

Thanks for the replies...yes the file is being opened as text...there shouldn't be a premature EOF character in there...but in general, what are my options while keeping this file open as text?

The calls to SetCurrentDirectory() are unnecessary. If the usage of this function is low, it probably makes no difference, but if it is an oft-used function, changing directories so many times is not efficient.

Yep, that's exactly what I did, just making sure it's the fastest way. Thanks for the help.

I use the extern in each header file for each global class object (all defined in another header file and included in only one cpp file) I am going to play around with the extern declarations to try and come up w/ a solution.

Thanks for the continued help...I seem to be a bit confused though...the spelling is correct (I always use a lowercase c for classes) Here is my file structure/layout: Header1.h --------- class cDataFile { ... }; ---------- Header2.h --------- #include "Header1.h" class cSomeClass { public: void SaveSomeFile(cDataFile*); <---- This is were I get the error }; ---------- Could you please explain what you said before in this semi-diagramatical way? Thanks.

I generally find it problematic to put variable declarations (as opposed to definitions) into header files. The tricks suggested about using #ifdef... are really just to trick the compiler into accepting a generally ill-advised way of writing code. My suggestion is to declare your global variables in the source file where they are originally created, not in a header file, and then every other source file that needs access to the global variables needs to use extern. For these other source files, they can #include a GlobalVars.h file that simply contains all of the necessary extern statements for the global variables. The main source file does not #include GlobalVars.h, as it is the file that is declaring them. The advantage to this approach is that variables (and the access to them) is not hidden through a set of #include, #define, and #ifdef statements. You are writing exactly what you want in a straightforward way that will be less prone to error and easier to understand. While it makes no difference to the compiler, it will be more understandable to anyone reading the code. Dave "You can say that again." -- Dept. of Redundancy Dept.

Thanks to everyone for their replies. Although I don't think that books can help me out any more because I am stubborn and never learn until I make the mistake. John's comment about creating another member function to get the details from the private members sounds the best way (don't know why I didn't think of it myself...been at it for 10 hours today, probably that's why!) Thanks, again.

Right!!!! I forgot about the "call by" rules!!! Thanks.

Thanks
