Help Files In a MFC Application

I just tried to add some text into the MyProg.Cnt file using the HTML/XML Editor with Encoding editor.

Nothing is displayed when I call up (from the Help memu option other than the following text:-

<<YourApp>> Help Index<br />
<br />
<br />
<< Write a topic here that discusses your application's main dialog.>>

Are they an example project that show the format you should use.

I was told by someone to use a Freeware program Cheetah.

But as its the first time I have tried to use help, I thought that Visual Studio .Net 2002 would have all I needed, just need to know how to use it.

Any articles/wed sites out there, please as not used HTML or XML, but I think could use it with a little effort.

I did not work on this type of application till now. Can anyone please help me or give me some directions.

Thanks

i know what you means. But i want to know other tech. Because if we set the file's attribute is "hide", user can easily unhide if they choose folder option/and choose unhide in windows.
I mean that i will hide all time even user set view unhide file. And just my program can set unhide attribute to the file only.

strtok, Find the next token in a string

Hi

I wan't to run my exe program and pass some arguments with the exe file. example:
MyProgram.exe "nr1,nr2,nr3,nr4,nr5"

This is some of the code:

int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
char *token;
char seps[] = ",";
token = strtok( lpCmdLine, seps );

This works ok in Visual C++, but i would like to do this in Emededd C++. There i get an error: error C2664: 'strtok' : cannot convert parameter 1 from 'unsigned short *' to 'char *'

How can I do this right?

Thanks!

try casting your lpCmdLine var to char*
strtok( (char*)lpCmdLine, seps );

It seems strange, cuz LPSTR is an ANSI string...

Hope this helps you,

Not if you are compiling for unicode, then LPSTR is unsigned short *.

Nono,
LPTSTR is a Unicode format (wide char) in UNICODE and ANSI when not compiling for UNICODE
LPSTR is always ANSI string (8bit)
LPWSTR is always wide char string(16 bit)

But I used to be confused by these too..

You're so right.
But regardless, it seems that something makes his compiler believe that LPSTR is defined as unsigned short *.

It seems like you've defined UNICODE (or _UNICODE, I can't remember the definition for compiling for unicode precisely). If thats the case, then LPSTR translates to unsigned short * instead of char *.
strtok requires char * parameters, if you intended to use unicode strings, you should use wcstok instead.

[EDIT]A GDavy has corrected me, LPSTR should be defined as CHAR * and CHAR should again be defined as char. But if the code you've given us is the same you're using for your embedded version, then somehow LPSTR must be defined as unsigned short *[/EDIT]

Hi,
In a Win32 Application I would like to check if command line parameters
/b /a is provided. The Messagebox show me the parametters like
/b /a but the if condition do not met it alwasy the else statment
that apply.

if ("/b" == szCmdLine || szCmdLine == "/a")
{
MessageBox (NULL, szCmdLine,"met",0);
}
else
{
MessageBox (NULL, szCmdLine,"Not met",0);
}

I did also chcked "//b" == szCmdLine. What I am missing?
Regards.

if szCmdLine contains other parameters besides /a or /b, you will need to do this.

if (szCmdLine.Find("/b") >= 0 || szCmdLine.Find("/a") >= 0) 
{
    MessageBox (NULL, szCmdLine,"met",0);
}
else
{
    MessageBox (NULL, szCmdLine,"Not met",0);
}
