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

Yes it is true
the value is 2

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.

 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 );

In your dialog's constructor, change the first parameter being sent to CDialog's constructor from IDD to MAKEINTRESOURCE(IDD_DIALOG_TEMPLATE) instead.
* Note that IDD_DIALOG_TEMPLATE is whatever name you have in the dialog's class declaration.

Hey thanks David,
I have seen the MAKEINTRESOURCE macro before. It seems kind of redundant doesn't it. Why bother converting to an INT when you could just use the other constructor.
Could you give an example of the IDD_DIALOG_TEMPLATE name? You said it is whatever name you have in the dialog's class declaration.
I'm still scratching my head. Please provide a snippet. Thanks again for the response. Jay

That macro converts to a string not an int.

Just look in your dialog's .h file for the value assigned to IDD.

Did you modify the dialog's constructor like I described?

Thanks David,
Be patient, this is coming to me.
I did mispeak on MAKEINTRESOURCE macro. It does indeed return a string.
Here is my call as it was
pDlg->Create(IDD_DIALOG1, this);
Here was my constructor
CDialogView::CDialogView(CWnd* pParent /*=NULL*/)
: CDialog(CDialogView::IDD, pParent)
{
//{{AFX_DATA_INIT(CDialogView)
// NOTE: the ClassWizard will add member initialization here
//}}AFX_DATA_INIT
}
From CFileDialog.h file
// Dialog Data
//{{AFX_DATA(CDialogView)
enum { IDD = IDD_DIALOG1 };
// NOTE: the ClassWizard will add data members here
//}}AFX_DATA
Are you saying I need to modify the constructor of my dialog?
Here is what I did for the new constructor
CDialogView::CDialogView(CWnd* pParent /*=NULL*/)
: CDialog(MAKEINTRESOURCE(CDialogView::IDD), pParent)
{
//{{AFX_DATA_INIT(CDialogView)
// NOTE: the ClassWizard will add member initialization here
//}}AFX_DATA_INIT
}}
Now for the call
pDlg->Create("IDD_DIALOG1", this);
I still get an assert. I'm not sure if this is what you meant.
Thanks, Jay

Should be:

Thanks David,
I think I'm making it more difficult and I think you've answered my question
CDialog one("IDD_DIALOG1", this);
CDialog two(IDD_DIALOG1, this);
Both of these work. So the answer is the template resource name is just the string representation of the ID.
If I derive a class from CDialog, I have to make sure that my constructor in the derived class would accomodate the string using the MAKEINTRESOURCE macro.
How did I do?
Thanks again. I learned something.

What is it that you are wanting to do that a CDialog-derived class does not already do? I must say that in 12+ years of using MFC, I've never used CDialog's constructor that takes a string. Maybe you have an example that shows its usefullness.

Compiled resources may be identified numerically (this is the usual case) or with a string. For example, you could have the following in your .RC file:
IDD_DLG1 DIALOG 0, 0, 210, 150
...
"DIALOG2" DIALOG 0, 0, 200, 200
... In the first case, you have a #define in your resource.h file for the value IDD_DLG1.
In the second case, you would use the lpszTemplateName form of the constructor, passing the string "DIALOG2".
The MAKEINTRESOURCE macro converts an integer resource identifier to a form that the resource loading logic recognizes, returning it as a string type.

Perfect! Thanks a bunch. It was a conceptual question. I have no reason to use a string but thought I should at least understand the concept. Thank you.
