Hi all, I need to create a child dialog for my mfc dialog-based application but I don't want to use a resource template, so I decided to create a CWnd derived class and create there my window and controls.
I can't find on the entire web one good example, can you be so kind to link me some guide or explain me how to create a dialog using CWnd derived class and how to manage its events (paint, lmouseclick, etc..) please?
Thanks for any help, a newbie

The derived class you want to use is CDialog. 
What features of a dialog are you looking for if you're not using a dialog template?
With MFC and Visual Studio, you can create a CWnd-derived class and add message handlers all with a few clicks of the mouse
(and a little typing to give your class a name).

I need to create a simple child window (a frame in the right of my parent's area) and I need to add some combo boxes and label (these controls change by user's preferences so they are not a fixed number)
I thought creating the child window dynamically without res template, adding dynamically controls based on user's preferences was a good idea
Otherwise i should implement almost 12 child template windows ._.!!
If you need clarifies, I could try to give more info
Thanks

You can create the controls at runtime, but you have to do the positioning yourself.
Another method (if it applies to this) would be to use a dialog resource with all the controls
you need, but the controls are hidden. At runtime you can make the appropriate controls visible
and reposition them easier because the layout is already partially done for you.

I definitely prefer placing controls by myself, but how to get Onclick event handler for a CStatic control for example?
Have I to use a derived class?

With MFC, a CStatic-derived class is simpler. Just add a WM_LBUTTONDOWN handler.

Yes, and change the size of the window / dialog to adapt it to the shown controls as well. I mean, 5 controls = one size, 10 controls = another size and so on.
It is the easiest way.

Hello. I'm engaged in some data scraping off a web page and need to set some list box items. I'm having no trouble setting some integers but setting character values is a pain in the butt. Here is a snippet of my code:
if ( strTag == "tradeYear" )
{
CString strYear = m_strSystemDate.Mid(0,4);
strTag = "value";
bstr = strTag.AllocSysString();
VariantInit( &vVariant2 );
vVariant2.vt = VT_UINT;
vVariant2.intVal = atoi( strYear );
pElem->setAttribute(bstr, vVariant2);
SysFreeString( bstr );
nCheckInputs++;
}
if ( strTag == "venueChoice" )
{
if ( bFuturesData == true )
{
strTag = "value";
bstr = strTag.AllocSysString();
VariantInit( &vVariant2 );
CString strVenue = "Electronic";
BSTR bstrVenue = strVenue.AllocSysString();
vVariant2.vt = VT_BSTR;
vVariant2.bstrVal = bstrVenue;
pElem->setAttribute(bstr, vVariant2);
SysFreeString( bstr );
SysFreeString( bstrVenue );
nCheckInputs++;
}
}
The first block, tradeYear, works just fine and sets the desired value but the second doesn't cahnge the value of the box? If anybody could tell me what I'm doing wrong that would be great. Thank you.

You can't write a C++ program using VB 5. VB is for creating Visual Basic applications, not C++ programs.

While this is obviously impossible, a bigger question would be, why on earth would anyone use VB5 at all ? I mean, even VB6 is a dead language.

Try something like this in C/C++...
int main (int argc, char *argv[])
{
int vb = *system("VB5");
echo(vb->convert(150, "binary", "hexadecimal"));
}
