Programatically creating a DataGrid Control on SDI? Possible?

MS Excel can be automated using COM and be made to do lots of things. If you want to control MS Exccel a lot, good idea would be to use COM. How much control do you want?

MFC is a C++ framework that wraps the Win32 API and makes it easier for you to code GUI apps. Actually non-GUI apps too, but it's advantages are more obvious when doing GUI apps.

Without having to spend countless hours developing my own "view", I'm looking to integrate any one of the "activeX" type controls as the main view in my SDI application. The Microsoft DataGrid looks nice, but i'm not really understanding how one could create it programatically.

Can someone point me in the right direction? It would be nice if I could just call Create() on it, but I can't seem to even declair and instance of "CDataGrid" or whatever they might be calling it. Any suggestions? Websites?

Thanks,

ON_CONTROL_REFLECT?

I have a button control that captures the BM_CLICKED event with ON_CONTROL_REFLECT; however, I also want the parent dialog to also handle the click event for the button. Basically, I want the button to have it's own event, but I want to see when the user clicks it. Anyone, I'm stumped on how to do this. I try GetParent()->SendMessage(WM_NOTIFY) in the button's function and I have the control having notify set, but it doesn't work. What am I doing wrong?

Thanks for any help!

Use ON_CONTROL_REFLECT_EX() - see MFC technical note TN062 for a description.

Which message is used in CEDit to draw the text in the edit box?
I wish to draw my own text instead of the one used in CEdit.

Anyone?
Thanxs in advance

You should use WM_PAINT i.e OnPaint. Is there any special reason you are subclassing the window instead of writing a custom CWnd class?

i'm subclassing CEdit instead of CWnd class because i need to make an edit box, but don't it to be displayed the way CEdit does it. So i was thinking that subclassing CEdit would be easier then subclassing CWnd. I need to make some fanciful edit box. Not sure whether i'm correct on that.

OnPaint for CEdit does not seem to be "painting" the text.

I'm just a newbie.

Thanxs for the help.

If you only need to change the text font, size or color then you don't need to do any drawing.

Hi All,

what seems to be the problem of this code:

#include <string>
#include <iostream.h>
int main()
{
std::string str1="Hello World";
std::str2=str1.substr(6,5);
return 0;
}

I get an error "error C2039: 'str2' : is not a member of 'std'"

Thansk/Regards
Sidney

Thanks/Regards

One more quick question...

why is it I can's directly output the str2 using cout ??

std::string str1="Hello World";
std::string str2=str1.substr(6,5);
cout << str2;

I get this error: "error C2679: binary '<<' : no operator defined which takes a right-hand operand of type 'class std::basic_string<char,struct std::char_traits<char="">,class std::allocator<char> >' (or there is no acc

You should use iostream not isotream.h

#include <iostream>

not

#include <iostream.h>

Then you need to prefix cout with std::

std::cout << str2;
