This is not the case; I've seen console applications that use MFC classes, CString for example. You are correct in that most MFC classes are GUI related and will be of little use however.

Thanks Steve.
The OP stated "by getting a rid of any reference to MFC" so I answered accordingly.
CString and the database classes can be useful in a console app 
Cheers!

Thank you Mark and Stephen for your responses . I am still trying and I am getting no where. As of now, I have no knowledge in MFC world.
Ideally, this what I would like to achieve:
When I run the application from a command line (No GUI), the following calls will be executed:
void StartCANoe();
void LoadCfg(string filename);
void StartMeasurement();
void CallCAPLFunc();
void StopMeasurement();
void QuitCANoe();
In other word, I will perform one measurement per execution of the application.
If this is achieved, I know what I need to do next.
I would really appreciate if you one of you is willing to take a look. If you are, please send an e-mail to:
mohamed.douffir@monotypeimaging.com
and I will respond with the zip file ((120k). I wanted to attach the zip file but I don't think codeproject allows attachments. I could be wrong.
Thank you.

hello, i have a problem when i try to load a bitmap to a CToolBar object.
i have a bitmap resource, and it is true color. I want to load it to my Toolbar object. but then, the buttons only display a full-black bitmap on them. When i change this bitmap on 16 colors, the buttons display them.
can anyone how to load a 24-bit bitmap on my toolbar?
this is the code:
m_dialogToolbar.Create(this);
m_dialogToolbar.LoadBitmapW(IDB_BITMAP4);
m_dialogToolbar.SetButtons(toolBarButtons,3);
m_dialogToolbar.SetSizes(CSize(rect.Width(),rect.Height()),CSize(16,15));
RepositionBars(AFX_IDW_CONTROLBAR_FIRST, AFX_IDW_CONTROLBAR_LAST, 0);
m_dialogToolbar.ShowWindow(SW_SHOW);

Maybe try using an image list instead of the CToolBar::LoadBitmap(), something like:
CImageList m_dialogToolbarImageList;
...
CBitmap bitmap;
bitmap.LoadBitmap(IDB_BITMAP4);
m_dialogToolbarImageList.Create(16, 15, ILC_COLOR24|ILC_MASK, 3, 1);
m_dialogToolbarImageList.Add(&bitmap, RGB(0x00,0xFF,0x00));
...
m_dialogToolbar.Create(this);
m_dialogToolbar.GetToolBarCtrl().SetImageList(&m_dialogToolbarImageList);
m_dialogToolbar.SetSizes(CSize(23,21), CSize(16,15));
m_dialogToolbar.SetButtons(toolBarButtons,3);

It still doesn't work. I mean, the method works but the buttons keep displaying the bitmaps only in 16 colors  My bitmap resource is truecolor. 
at least now , even if the bmp is 24 bit, it shows it, but in 16 colors

Sorry I didn't realize you actually wanted to see your 24 bit bitmaps in true color 
Just kidding.
I fixed the code in my previous post (the imagelist construction code).

What is a handle? I see this alot in MFC. Is it some type of pointer or reference to an object or resource (like a window or button)?
Thanks,

Not exactly a pointer but it in fact an identifier of, for instance, windows and files.
E.g. when you ask to the OS to create a window, it will return to you its HANDLE. Then, each time you will need to identify that window with the OS (for example to send a message to it), you will have to pass to the OS that returned handle.
However the handle is not a pointer to the window because the OS cannot return to you a pointer to memory which is relocable; giving you a handle, instead, introduces an indirection layer (a kind of table linking handles to memory addresses), warranting that the handle value will not change on memory relocation.
hope that helps.

A handle is some opaque data structure used to represent some system resource. The term “opaque” means the user should not assume anything about the representation used and the actual representation used could change from OS version to OS version. A handle could be a pointer, an index into a table or something else but it doesn’t matter to the user as all access is via APIs.

Hi,I suggest you to read 《Programming for Microsoft Windows》by Jeffrey Richter，In the chapter 3 of the book，Jeffrey described the handle clearly.

I am making a autoupdater, using a CEdit text box to show a logg during the update progress, however
only static_text and the progress bar updates as the tool runs the performed action, but only updates when the action is complete.
this code is called on each update stage, progress bar in the code bellow updates as it should, but not the SetWindowText, untill the "update button" function is complete.
void CAutoUpdaterDlg::OnBnClickedUpdate()
{
CEdit * s = static_cast<cedit *="">(GetDlgItem(IDC_STATIC_MSG));
s->SetWindowText("Please wait, update in progress.");
CButton *b = static_cast<cbutton *="">(GetDlgItem(IDC_UPDATE));
CButton *b2 = static_cast<cbutton *="">(GetDlgItem(IDCANCEL));
b2->EnableWindow(false);
b->EnableWindow(false);
sprintf(DynamicBuffer,"%s","Looking for updates...\n");OnUpdateScreen();
GetList(); // Downloads, test the list for readability
// Read the file into memory
file_LoadIntoMem("UpdateList.txt");
// Download the files read from the UpdateList
sprintf(DynamicBuffer,"%s","Downloading new content in progress...\n");
OnUpdateScreen();GetTheFiles();
// After reading it into memory, delete it.
CleanUp();
// Finaly enable the buttons again
b->EnableWindow(true);
b2->EnableWindow(true);
s->SetWindowText("");
}
void CAutoUpdaterDlg::OnUpdateScreen()
{
char LocalBuffer[10];
itter++; lineslimit++;
sprintf(LocalBuffer, "%d", itter);
CEdit * p = static_cast<cedit *="">(GetDlgItem(IDC_Window));
// static message for now
strcat(WindowBuffer, LocalBuffer);
strcat(WindowBuffer, ": ");
strcat(WindowBuffer, DynamicBuffer);
int Size = strlen(WindowBuffer);
p->SetMargins(5,5);
p->SetWindowText(Convert_A_To_DA(WindowBuffer));
CProgressCtrl * progress = static_cast<cprogressctrl *="">(GetDlgItem(IDC_PROGRESS));
progress->SetRange(0,MaxRange);Progress++;
progress->SetPos(Progress);
if (lineslimit == 11)
{
int size = strlen(WindowBuffer);
for(int i = 0; i <= size+1; i++ )
{
WindowBuffer[i] = 0x00;
}
lineslimit = 0;
}
int MemSize = sizeof(DynamicBuffer);
for(int i = 0; i<= MemSize+1; i++)
{
DynamicBuffer[i] = 0x00;
}
}

Try using the UpdateData(...) function for the dialog before you referesh it's window or ask it to display something. If you call UpdateData(FALSE) it should write whatever you have in the SetWindowText(...) or value variable for that control onto the screen.

UpdateWindow(); this function worked perfect, thanks.

Hi,
I am new to c++ and I will use it in my thesis on image processing.
I wrote a piece of code to read a ppm image file. in order to read the magic number (the number indicating the type of the image file whether it is ppm, bmp, jpeg or etc. this magic number is in the header section of the image) i create a char pointer magicNumber:
char *magicNumber;<br />
magicNumber = new char[2];
and pass it into the function PPMreadHeader. My intent is to fill the pointer inside the function and write the magicnumber in the console outside the function.
i have an array in the PPMreadHeader fuinction in order to read the file line by line. I have a local char pointer "word":
<br />
char line[255];<br />
char * word;
when i read the magicnumber (it is "P6" for ppm files) i assign it to the local pointer word:
word=line;
if i try to write the magic number in the function using the local pointer:
cout<<word<<endl;
there is no problem, it writes p6 to the console. however, if i first copy the word into the magicnumber pointer that i create in the main function:
*magicNumber=*word;<br />
*(magicNumber+1)=*(word+1);
and then try to print out the pointer to the consolelike below:
cout<<"magicNumber: "<<magicNumber<<endl;
then it writes:
magicNumber:P6ııııİİ
which not i want. it writes the p6 which is what i want to write to the console, but it writes more than p6. within the function when i write the local pointer "word" it just writes the P6, nothing more. Could you please help me on this.
You may advise other alternatives to write the magic number on to the console but even you do this, i still want to learn what is wrong with my coding. i spent a lot of time on this and i could not fix it.
Thank you in advance.

char* strings in C/C++ need to have a null character at the end. if you allocate 2 chars for a two-char string, there's no place for that null to go.
so, you should allocate 3 bytes for magicNumber, and set byte #3 to 0. then use a string copy function (like strcpy or even better, strncpy) to copy the strings from buffer to buffer; that will copy the null character along, too.
so, best of all, use a C++ string class, like std::string, to handle your strings. that will eliminate the need for buffer allocation, worrying about nulls, etc..

Modify it to ,
char line[255] = { 0 };
char * word = NULL ;
This should solve your problem.

Hi All,
I'm looking to team with someone who has written an HTML parser (or can write an HTML parser). My scanners\pasrsers are generally LALR (from my Compiler Theory days in college), which is a bit different from HTML.
The requirements are loose - I don't need a DOM. Something similar to below would work well (written in C\C++):
while( EOF != document )
{
Element = GetNextElement( document )
}
Element should look as follows:
struct _E
{
string element
vector<string> attributes
string value
} Element
I'm interested in the html 'primitives': < P > tag, < H# > tags, < TITLE >, < TABLE > (no need to break out the < TD >s and < TR >s. As I said, I am flexible. There is no need to return < HEAD > or < BODY > (hence the request for 'primitive' elements). To summarize, I want the 'leaves' of the tree (leaf nodes) - not the stuff encountered on the way down (branches). For proof of concept, attributes can be empty (they may be required later).
There is no need to convert between entity codes and characters. For example, does not need to be converted to it's corresponding white space (but it may in the future). Same with the C\C++ '\t' - character 0x09 can stay that way (for now).
Additionally, the co-author will be responsible for file rotation. Think of it as a log file for this purpose. Assume there will be at least 8 files to rotate (first in, first out). The data to be read and written will be a vector< string >:
vector< string >: ReadFile( Some sort of Time identifier )
void WriteFile( vector< string >: )
The algorithm does need to be deterministic (duh) - run on the same document, it must produce the same results each time.
So, the co-author should:
* create GetNextElement( )
* file I/O
* file rotation
* well document it - the byte scanner and tokenizer should take at least 3 pages. Aho, Sethi, and Ullman managed to produce 350 pages on this portion of a front end in Compilers - Principles, Techniques, and Tools[^].
I will:
* add the usage code of Element
* remaster screen shots in Photoshop
* coordinate the publication
I'm anal about article write ups. I toss out 5's for three sentence articles with a pretty Screen shot, but that is not what I expect of myself. Please see here[^] for my articles (so you can get a feel for what I expect).
I generally post to two sites: Code Project and Code Guru. It would be nice (but definetly not required) if the co-author had a Code Guru account.
Any takers? If more than one taker, I'll ask that you fight it out amongst yourselves, or take on an additional co-author. I' don't want to have to choose. I'm actually more concerned no one will step up to the plate, so don't be shy.
If successful, I want to move the Project to SourceForge. At that time the co-author can share in the Administrative responsibilities. The project will be called WebGrits. You'll understand later when the poetry is in motion.
BTW, my portion is complete  It is another Crypto++ project based on hashing.
