FloodFill doesn't works on printer. Are there other solution to colorized a ellipse? I need your help
many thanks

Why not just use CDC::Ellipse()
Just create a CBrush with the characteristics you need for the fill, a CPen for the border (if any), select them into the DC, and then call the CDC::Ellipse function.
How are you drawing the ellipse now that requires the use of CDC::Floodfill?

Because the ellipse is use to graphic chart pie and i have many colors in the ellipse for each part.
I haven't idea how to fill each part inside my ellipse.
Maybe used fillrgn but i don't know how do this?

Can you FloodFill() to an in-memory DC, and than copy that to the printer's DC?

i do this directly on my printer (i print my view)
void myview::OnPrint(CDC *pDC, CPrintInfo *pInfo)
{
if (!pDC || !pInfo) return;
pDC->Ellipse(p1.x-(int)r,p1.y-(int)r,p1.x+(int)r,p2.y+(int)r);
pDC->FloodFill(p3.x,p3.y,0x0);
.....
}
In fact i draw all with my current pen: ellipse, part of pie and i do floddfill to fill each part.
must i used CreateCompatibleDC?

As I'm not much into GDI, I do not know. It wouldn't hurt to try, though.

You can use GetDeviceCaps to see if the device supports your drawing operations.
if (pDC->GetDeviceCaps(RASTERCAPS) & RC_FLOODFILL)
// flood fills are supported
...
if (pDC->GetDeviceCaps(CURVECAPS) & CC_PIE)
// pie wedges are supported
...
etc.
If they aren't supported by the printer device then you may need to do your drawing to a memory
DC and blit it to the printer DC.

I have created an MFC ActiveX Control through the wizard. In the 2nd Step of the wizard I have enabled the checkbox saying “Available in Insert Object Dialog”, so that I can use my control in Microsoft Office Application like MS Word, Excel, PowerPoint etc using Insert Objects.
I am using property sheet to change the text contents of my control. For that I followed the steps mentioned the MSDN Example CIRC.
http://msdn2.microsoft.com/en-us/library/c6hzbzz6(VS.80).aspx
My control features the following characteristics.
• Changing the painting behavior of an ActiveX control
• Adding stock properties
• Adding custom properties
• Responding to mouse events
• Adding custom events
• Using text and fonts
• Implementing ActiveX control property pages
• Using simple data binding for control properties
But at present I am stuck up problems.
1. Using property sheet I can update the text contents in ActiveX test container. But it doesn’t get updated in Word, and other Office Applications. In fact its not even recognizing any of the event fired by the user (like changing the color on mouse click, key press etc) in any of the office application.
2. I am using this control for assigning digital signatures to a document. For that I am using X509 libraries. But these libraries use Common Language Runtime (/CLR) Support. And if I enable CLR from the project settings, the control crashes while loading on the Office application, ultimately crashing the entire document.

Currectly I m working with "Programming Windows by Charles Petzold" and "Programming Windows with MFC second edition by Jeff Prosise" for learning Win32 and MFC . Are these resources will enough? or I'll need some more resources that you programmers would like to suggest.
Thanks a lot,
Regards,
Sumit Mandal

I feel these two are enough to learn MFC. However I prefer you start first with Prosise and after getting feel of MFC start reading Petzold.

Paresh.

Have you some trouble to choose a title for your threads ?
Win32/MFC is too generic to be a valid description of what you're asking for... 
|
|
|
|

I agree with Paresh except I'd learn them in reverse order. Knowing windows programming
fundamentals (Petzold) first will make MFC (which is mostly a C++ wrapper for Windows APIs)
much easier to use effectively.
Just my opinion

Can the icon size of the icon to be displayed on a CButton be set
|
|
|
|
|
|
I believe button icons are displayed centered on the button and if the icon is bigger than the
face of the button it is clipped.
If resizing the button so the icon fits isn't acceptable then you'd need to resize the icon first
before setting it to the button.

What class is your view derived from?

are there cases where we should write our own copy constructor and assignment operator overloading in the class?
Thank you.

Please refer this[^].
When you have atleast a single member varibale as a pointer variable.

If your class have member variables that are pointers and/or allocate memory, you have to write a copy constructor and assignment operator. Probably even a "==" operator.
If you don't, the compiler will create those for you and they won't behave the way you want them to. It creates shallow copies, performs member wise comparison and so forth.
You can assume that you should write a copy constructor for each class you develop.

Yes. The first example that comes to my mind is for smart pointers for example. Another example would be for a string class (you need in fact to copy the contents of the char pointer, not just the char pointer itself).

hi
what ifdef do i need to use to run my application on desktop pc(x86 compiler) in visual studio 2005(VC++)?

thanks.

These two platforms run different versions of Windows and are not binary-compatible. In other words, you need two different .exe files, each compiled and linked for the appropriate OS. They use the same processors but the OS runtime DLLs are different and different APIs are supported.

i know that i'll be getting two different exe's. but i need the #ifdef for compiling under x86 platform. for windows mobile i am using #ifdef POCKETPC2003_UI_MODEL.
