Go ahead and create a new, temporary project with that option checked. Now compare the settings between the two projects.

Hey,
I'm trying to read Integers from a binary data file. I've been using the CArchive Read(char[],int) function, then converting the byte using CString Format("%X",char[i]).
I'm testing all the values against a HEXeditor, and things work well, but when the byte i read has a 1 in the lefternmost position, the value that my char array holds is the 2's complement for that value.
EX. when it reads "B3"(1011 0011) from the file, my value at char[i] == "4D" (0100 1101)
A. why is this happening?
and ...
B. is there someway i can zap it back to the original number?
Thanks a lot,
Mike

just a guess, but could it be a signed/unsigned conflict.

If the values were written to disk as char, they need to be read as char. If they were written to disk as int, they need to be read as int.
Consider the following:
CFile file(..., CFile::modeCreate | CFile::modeWrite);
int nAge = 42;
file.Write(&nAge, sizeof(int));
file.Close(); The file contains 4 bytes that look like 0x2a000000. To read that same value back in, I'd use:
file.Open(..., CFile::modeRead);
file.Read(&nAge, sizeof(int));
file.Close(); The variable nAge contains the value 42. Had I used this instead:
file.Open(..., CFile::modeRead);
char str[4];
file.Read(str, sizeof(char) * 4);
file.Close(); The variable str contains the value 0x0000002a. I think the big/little endian concept might be messing you up. PJ's suggestion is plausible, too.

I'm trying to Navigate a web browser ctrl to a url that uses basic HTTP authentication (username, pwd) without having the user to wait for the IE username/pwd dialog. Is there any way to package this info along with the request? I'm guessing I need to somehow pass this info in the Headers arg.
I'd be grateful for any pointers to code snippets or examples. Thanks!

Wow, I knew that username and password could be specified in a ftp:// link, but I did not realize it could be used with http:// too. Thanks!

My c++ program when run on a different machine asks for MSVCP60.DLL which doesnt seem to be present on that machine. From my initial search I found that I will need this DLL if I use STL. I then removed all the STL references from my program but I still get the error. Does C++ 'string' require this DLL? Any other pointers?
Thanks.

string is STL too

You need this dll if you use Standard Library (anything from the std namespace) AND you link your libraries dinamically.
|
|
|
|

Hint: link statically to all libraries, and you should be OK.

Open the visual studio .NET command prompt (or open a new command propmt and run vcvars32.bat for VC6). Navigate to the directory that your binary is in and run:
dumpbin /DEPENDENTS <your_binary>
Alternatively you could just run dependency walker

any idea why this DLL is not present in a windows OS by default?
is there a way to detect from my EXE if this dll is present and show a meaningful message?
|
|
|
|

Because it's distributed with visual studio.
When you are preparing to distribute applications check the dependencies first. Your development PC should have all the required DLL's on it, which you can put in the same directory as your executable. You will however have to check the licensing conditions of the DLL's if you need to include them in software which will be sold.
For this reason it's important to always test software on a 'clean' machine that doesn't have visual studio installed.
Showing a meaningful message is a little more difficult - AFAIK you would actually have to load the DLL at run time rather than relying upon explicit linking. I would recommend against this, a proper testing procedure should remove the need for this type of message.
Good Luck!

Just one last question in this thread (I have created a new thread for a related question).
Since STL is all templates, it should all be replaced inline in the code(not exactly, but kind of equivalent). So where does the question of having a seperate DLL for STL come into picture?
Thanks.

Don't quote me, but from what I can remember the largest part of of the STL that is in a separate DLL are the IOStream classes. Yes, you're correct the majority of the STL is contained in header files.

Hi every body,
I need some help here. Please help me doing my final year project. 
My question is "How to create bitmaps using createcompatibleBitmap function in VC++ from an array of pixels"
I will pray for eveyone helps.![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)
Thank you in advance .

You need to use CreateDIBitmap() to create from an array of pixels!

This is a loaded question. I didn't seem to find it handled here, so if this is not the right place, let me know.
What would it take to get a VC++ program with MFC to work under a Macintosh computer. I will assume the obvious for one of the tasks in that I have to remove MFC. touching on that fact, how does one go about doing something of this nature? I'm also assuming I would have to recompile the program on a Mac? How does one go about doing that? Is there a VC6 for a Mac?
Is there anything else that I am missing?
Again, I'm very sorry for the loaded question. If there is an article that someone can point me too, great!
Thanks for your patience.

Have a looksee at this:
www.wxwidgets.org[^]
It is a cross-platform GUI toolkit, similar to MFC (and can even co-exist with MFC to an extent). There are sections there about porting MFC applications to wxWidgets.

Microsoft came out with a Mac VC cross-compiler based on VC4.x several years ago. We bought it, but never used it. Not sure if it is still available, though...
onwards and upwards...
