I believe you can use GDI to render the text to a window or a memory context and then save its contents as an image.

These are the function for drawing using GDI Font and Text Functions[^].

You can try to look up for memory DC and how to save it to a image.

Hi all,

How can I convert an UINT into wstring.

Initially I convert it into CStringW, using Format(). But wstring there is no such thing. I want to avoid MFC here.

Any idea?

Thanks

I appreciate your help all the time...

#include <sstream>

UINT i = 100;
std::wstringstream str;
str << i;
wstring s = str.str();

Thanks,

How about this way?

		<br />
wchar_t buf[8];<br />
wstring str(L"");<br />
_itow(12, buf, 10);<br />
str.append(buf);

Actually I want to do this for values from 0 to 31 only. So I think my buffer size is enough.

I appreciate your help all the time...

How to Uniquely identify a Windows OS installation

5-Nov-08 19:38

Sure you can do this way but I will recommend using wstringstream. It is more general, you don't have to worry about buffer size.

I'm writing a software application which I intend to sell and I'm implementing a number of security features for licensing purpose.

I was wondering if there is a way to identify a Windows OS installation. Example is it possible to get Windows Serials?

your thought is not realism ,because maybe many people use the same SN of windows ,i think you can get some hardware information to deal with that ,such as net card physics address

I agree with your criticism, but you should point it at the original poster (JackWack).

Hi I wanna know how to change all of controls of a MFC exe, like skin programs(SkinCrafter for example)
I have wrote some function to subclass all of a controls of a dialog, it enumarates all child windows and subclass all buttons for example, I created a class derived from CDialog, and call that function on it OnInitDialog() method, and I derive all my dialog's class from this one, so all of it's buttons will be replaced, this works great for me, but want to know how these skin programs can change all of controls of an exe file, a piece of code or a good guidline will help me much
Please answer if you know something about this
Thank you all

Hi,
I'm having problems converting some compiled code in VC++ 6.0 under my new Studio 2005 environment.

VC++6.0:

<br />
   ON_MESSAGE( MY_MESSAGE, OnUmMyMessage)

the .H declaration for above...

<br />
   afx_msg void OnUmMyMessage(EGS_CONSTATE conState, CMyMsg *msg);<br />
<br />
   typedef enum { STATE1, STATE2, STATE3, } EGS_CONSTATE;<br />
<br />
   class CMyMsg : public CMyOtherClass<br />
   {<br />
      public:<br />
         char  data[MAX_MSG_SIZE];<br />
   };

The compiler error I get is:

error C2440: 'static_cast' : cannot convert from 'void (__thiscall CMyVisDlg::* )(EGS_CONSTATE,CMyMsg *)' to 'LRESULT (__thiscall CWnd::* )(WPARAM,LPARAM)'

How can I make my arguments or message map look like a (WPARAM,LPARAM) ?

Thanks!

What about a cast? Wink | ;)

I tried casting inside the message map function as:

<br />
<br />
ON_MESSAGE( (WPARAM) MY_MESSAGE, (LPARAM) OnUmMyMessage)<br />
<br />

but that only gave me errors

CPallini5-Nov-08 9:57

CPallini

5-Nov-08 9:57

You made the casts in the wrong places, change

afx_msg void OnUmMyMessage(EGS_CONSTATE conState, CMyMsg *msg);

afx_msg void OnUmMyMessage(WPARAM wConState, LPARAM lMsg);

and then, in the function definition

afx_msg void OnUmMyMessage(WPARAM wConState, LPARAM lMsg)
{
  EGS_CONSTATE conState = (EGS_CONSTATE) wConState;
  CMyMsg * msg = (CMyMsg *) lMsg;
  //...
}

more insight,

there may be compiler settings that are not allowing this. In other projects that i've worked with, there is no problem with what appears above (in 6.0 or Studio 2005).

The prototype changed between VC6 and VS2005

LRESULT CMyWnd::OnMyMessage( WPARAM wParam, LPARAM lParam ) <br />

In addition to the other comments, I happen to think this is a GOOD change. I've had to fly from India to Northern Ireland to fix a bug I made my using the wrong prototype for a message handler. The casts in the MFC macros hid my mistake during compilation, and it took me ages to track down the stack corruption.

I took the hint as was paranoid from then on - but anything a compiler can do to stop me making dumb mistakes and fine by me.
