Yes, if you give your program to a friend they must have the correct DLLs resident on their machine. This is generally not a problem but older machines may have a MFC42.dll that is out of date. ComCtl32.dll is another one to watch out for but machines with recent OSs and service packs should be fine.
Regarding BOOL and bool, BOOL is a type defined as an int in windef.h. bool (lower case) is a built-in variable type having a size of 1 byte and this is from the standard. It is best to leave BOOL as BOOL because they are different types as of MSVC v5.0.

Okay. Thanks.
First, I would really want to multi-thread using DLL (dynamically). I will post the errors as soon as I get access to the source at home.
One more question about MFC syntax. I learn from Deitel & Deitel to using "0" instead of "NULL." However, MFC uses "NULL" consistantly. Should I use "NULL" as Promise implements it?

Okay. I tested two versions of multi-threaded DLL.

I would like to compile MFC using multi-threaded DLL, thus making the program smaller.
Thanks,

Okay. I figured out the problem. The problem was there were mismatch settings in the project. The probject was default to Applicantion(exe) and Standard Windows Libraries. I had to set the project to use "Shared MFC DLL" instead of Standard Windows Libraries.
The executed size shrinks from 1.5mb to 100k in debug mode.

Another question guys. This time it should be REALLY simple but I'm too tired/lazy to look it up. Here goes:
I made a map editor that in the end scans the map you made and saves it in a two-dimentional array. Then it opens a file and writes the array to it.
The problem is that it's saved in one row and I'd like it to show as a matrix when you view the file.
So how do I instruct the FilePointer to drop a line?
By the way I used the WriteFile finction and all that API stuff, not MFC.

It's an Aussie drama, though christian claims it to be a soap oepra. I think it's not because the issues that are quite normal and not "my evil twin stole my mutant baby" and stuff like that.
It's about the lives of the people in the same street.

Of course it's a soap opera. And surely they've run the "my evil twin stole my mutant baby" plot by now? They've done everything else already.

OHHHH! Neighbours...yes I know what show your talking about now...We do get it...
I've never really watched it though...Soap...no way...you don't know Soap's until you've seen some sh*t day time television. Hollywood style...horrible...people fly and have sex with each other's other! and oh my god...all the people are beautiful...enough to make ya sick...Neighbours though...naw! it's more like Britain's Are you being served.

Hey Guys i have a DLL that integrates with explorer and when i add my own functions that i export it causes the DLL to crash and therfore explorer any ideas.
Peter
|
|
|

A possible reason could be the export order of your functions. Explorer may import an extension DLL using ordinal numbers for the functions that it imports. By exporting a function of your own, you may have inadvertantly changed the ordinal numbers of the functions you are exporting.
Try right-clicking your DLL and using QuickView to see the order they have been exported in. If they are incorrect for explorer (assuming it uses this method), you will need to reorder yout export list.

Hey guys
I have a DLL that integrates with explorer which has MFC support. Anyway the program works fine normally but occasionally when one of my dialogs is displayed it comes up either as a the menu bar and then i have to drag it out to see the window or it comes up very small. has anyone got any ideas why this happens. It usually happens on the 2nd time i use the dll or later never on teh first.
This gives me the idea that memory isn't being propally deallocated.
Cheers
Peter

Hey Guys
When you have a pointer and want to get it to point to an array is it better to:-
pointer = new BYTE[ArraySize]
or
pointer = (BYTE*)malloc(ArraySize);
Peter

new, every time. Because you need to remember to delete new and to free malloc, it's better just to always use new. It uses malloc internally anyhow, but you should prefer new because it calls constructors and destructors on delete.

I am looking for a function where I can pass a bianary string to a function that will return that value in Hexidecimal notation. The incoming string could vary in length. The output string will always be double what the input string will be. Here is an example of what I would like:
Input: C++
Output: 43 2B 2B
If possible I would like to eventually convert this to a compiled .dll in C++ that I can access within VB. The usage of this in VB is stricly due to a company restriction. I feel this proccess would be much more efficient in C++.
Thanks again ahead of time.
