I think one of the projects here on CodeProject uses this library.
I have not used it in a project yet.

Use ShellExecute() instead.

What does your code look like that did not work?
"Ideas are a dime a dozen. People who put them into action are priceless." - Unknown

ShellExecute(NULL,"open","C:\\help\\index.htm",NULL,NULL,SW_SHOWDEFAULT);

I assume a browser window did not open the specified file. What value did ShellExecute() return?

Yes it is true

Look at the link I provided you earlier. 2 = ERROR_FILE_NOT_FOUND. That should be easy enough to diagnose.

Does it work with other .htm files? If you open Windows Explorer and go to the c:\help folder, does double-clicking on the index.htm file open the browser? Are you sure the extension is .htm and not .html? Have you checked the file association in Windows Explorer to make sure that .htm files have an associated application?

What you have should work. Given that it does not, something else is amuck with your machine. This is just a grasp but what if you replace the first parameter with a real window handle instead of NULL? This way if the browser needs to report an error, it can.
Windows Explorer might be compensating for something that is missing. Use FindExecutable() to retrieve the name of the .exe that is associated with the .htm file.

Don't worry it worked apparently it turned out that the file path was correct but the file name of my file is index.html and not index.htm.
Thanks for ur help in debugging and sorry for wasting your time

I suspected that but you did not indicate it was a problem so I pursued other possibilities.

If the net result is that you learned something, how has time been wasted?

 Hi...
My program is recieving data at 9600bytes (with standard settings), in chunks. 40 or more characters at a time. When the Data is displayed straight away on the screen, everything is cool.
But when I do simple calculations, it misses a lot of characters, and from 40 I might only recieve 20! and some characters turn to little squares.
I have tried reducing the amount of Data transfered to 5 characters, but even so it misses a few, without any pattern.
Is it possible to build a buffer quick enough to store all the 40 characters, then do the calculations of them.
Please give me some suggestions...
Here's part of my code.
void CChildView::SortData(LPCTSTR pszData)<br />
{<br />
<br />
TCHAR buffer[10];<br />
_tcsncpy(buffer, pszData, 10);<br />
<br />
char AsciiStr[10];<br />
WideCharToMultiByte (CP_ACP, 0, buffer, -1, AsciiStr, 10, NULL, NULL);<br />
<br />
static char AsciiBuffer[11] = " ";<br />
static int nPass=0; <br />
<br />
AsciiBuffer[nPass++] = AsciiStr[0];<br />
<br />
if (nPass == 10)<br />
{ <br />
ofstream testFile( "test.txt", ios::app );<br />
testFile << AsciiBuffer << " ";<br />
testFile.close();<br />
nPass =0;<br />
} <br />
<br />
DisplayData(pszData);<br />
}
Maybe I should store the characters 1st, then convert into Ascii, But how do I convert an Array of Unicode into Ascii?
Thanks heaps!!!

it'd be a good thing to make a separate thread dedicated to receive data and putting it into a buffer an another (or the main thread) taking this buffer and treat it.

When creating a dialog you have the option of two constructors
CDialog( LPCTSTR lpszTemplateName, CWnd* pParentWnd = NULL );
CDialog( UINT nIDTemplate, CWnd* pParentWnd = NULL );
All the examples I have ever seen use the latter (UINT nIDTemplate). Just for my own edification
could someone tell me how to use the first constructor. I've never seen an example of this. Where do you find the TemplateName? These must be templates created in your code?
The first constructor parameter LPCTSTR lpszTemplateName appears in quite a few constructors, for example:
CFormView( LPCTSTR lpszTemplateName );
CDialogBar::Create
BOOL Create( CWnd* pParentWnd, LPCTSTR lpszTemplateName, UINT nStyle, UINT nID );
CDialog::Create
BOOL Create( LPCTSTR lpszTemplateName, CWnd* pParentWnd = NULL );
CPropertyPage( LPCTSTR lpszTemplateName, UINT nIDCaption = 0 );
COleDBRecordView( LPCTSTR lpszTemplateName );
CRecordView( LPCSTR lpszTemplateName );
