Hi,
thanks for very good works.
BoundsCheck report that an error at the
SelectClipRgn((HDC)GetDC(), hClipRgn);
which the HDC is not valid.
I change the (HDC)GetDC() to GetDC()->m_hDC
this time the SelectClipRgn just return an
ERROR if you change it to:
if(SelectClipRgn(GetDC()->m_hDC, hClipRgn)==ERROR)
AfxMessageBox("ERROR");
it seems that some thing is wrong with the
hClipRgn.
Anyone can help me?
Thanks

Dear All,
I well appreciated your program (CxSkinButton) and I like it a lot espacially the interaction between the mouse and the check box (eyes with different color ; blue eye, red eye and gray eye). In your code, you are using for each check box different bitmap with the same size. I would like kindly ask you 2 questions :
1- How can I use a bitmap bigger than that used in your code ( I want to use a bitmap that has a size bigger than IDB_EYERED, IDB_EYEBLU or IDB_EYEGRAY.....) ?
2- When running the executable file of your code, How can I switch blue eye with red eye by clicking somewhere and without clicking on the check box ?
Thanks a lot for your help

Hi,
first, thank you for the class.
Second, Visual Studio reported a memory leak to me at line 227 and 237 in function DrawBitmap, when you delete the previously created compatible DC. I changed the code to call the CDC member function DeleteDC and everything is fine now
< DeleteDC(dcMask);
> dcMask.DeleteDC();
< DeleteDC(dcBmp);
> dcBmp.DeleteDC();

pleas help me
I'm quite new to vc++ 6.0, i can see the CxSkinButton class, but it dosent shows ...
I kan do work with classes and objects, but that Class Wizard is complicated
"Create (or edit) a member variable for each button you want to customize as CxSkinButton. If the Class Wizard doesn't show the CxSkinButton type, select CButton and then edit the code manually."
please help me, thx

Maybe you are here:
cxskinwzd.jpg (32.8 Kb)
Use CButton as variable type and click Ok, then open the header where the button
has been declared and replace CButton m_button1; with
CxSkinButton <br />
m_button1;
|
|
|
|
|
thanks man, that was the problem, i couldnt find the object definition m_button in the header files ... now is solved
you are so kind, I have an another question to you, why all these Control IDs no longer in use (IDC_...) cant be removed directly from the Class Wizard, what is the meaning that doing that manually and deleting them from the Resource.h ?
thx allot Davide

|
|

and with the View\Resource Symbols... menu?
|

thanks again, i made a foll of my self hahaha

I am using this class as the child of a CFrameWnd derived class and the ON_UPDATE_COMMAND_UI() handlers that I have set are not getting called.
Does anyone know why?
Thanks.

void CxSkinButton::FillWithBitmap(CDC* dc, HBITMAP hbmp, RECT r)
{
if(!hbmp) return;
CDC memdc;
memdc.CreateCompatibleDC(dc);
memdc.SelectObject(hbmp);//parameter should be a pointer?
int w = r.right - r.left;
int h = r.bottom - r.top;
int x,y,z; //what does x,y,z mean?
int bx=GetBitmapWidth(hbmp);
int by=GetBitmapHeight(hbmp);

DeleteDC(memdc);
}

//I can not understand deffernce between return 1 and return 0.
sorry I am poor in English ,and quite new to vc++

I was about to use your class when this class be problem.
I'd like to change whole screen area and buttons in the area over scaned image.
but, whole screen area images are not scaned well.
I added derivative buttons to CxSkinButton, loadbitmap of #2 be performed but getbitmap of #3 be not.
1: CBitmap tempBmp;
2: BOOL bRet = tempBmp.LoadBitmap(IDB_MAIN_BACK);
3: int nRet = tempBmp.GetBitmap(&m_backBM);

I can't see the problem
|
|
|
|
|
In SetSkin() I have found on my machine that this call fails:
SelectClipRgn((HDC)GetDC(),hClipRgn);
but can be fixed by substituting:
SelectClipRgn(GetDC()->m_hDC,hClipRgn);
|
|
|
|
|
LRESULT CxSkinButton::OnBMSetCheck(WPARAM wparam, LPARAM)
function should be changed -
instead of ::PostMessage(hwnd2, WM_CXSHADE_RADIO, 0, 0);
better too use ::SendMessage(hwnd2, WM_CXSHADE_RADIO, 0, 0);,
otherwise, messages may get lost, for instance if you want to
set radiobuttons states from OnRadioButton() functions.

Thank you!

I forgot to delete an object in the file xSkinButton.cpp at Line 363:
HRGN hr=CreateRectRgn(pRects[i].left, pRects[i].top, pRects[i].right, pRects[i].bottom);
VERIFY(CombineRgn(hRgn, hRgn, hr, RGN_OR)!=ERROR);
if (hr) DeleteObject(hr);

Cheers for great class, although I have one minor suggestion...
I recently had to write software for all flavours of Win32 where there was a danger of being run under Win95 pre IE3 (albeit a very minor chance).
I was willing to sacrifice the mouse tracking under this particular OS (95 w/o IE3) so I altered the code to use GetProcAddress() to test for existance of TrackMouseEvent().
This will at least allow the software to run on 95 w/o IE3.
I was wondering why this hadn't been done, are there some subtleties that I'm missing?
Thanks,
Neil

Skipping the call to TrackMouseEvent( ) simply kills the hover feature.
Calling GetProcAddress() it's safe, anyway there is a chance for win95
without IE3: the class calls _TrackMouseEvent() , not TrackMouseEvent() .
_TrackMouseEvent() was inserted into common controls dll, "comctl32.dll",
so if you ship your program with a setup that incudes the updated version of
Mfc42.dll and Comctl32.dll (and maybe Advapi32.dll and Oleaut32.dll ),
the button can use the hover feature.

Unfortunatly I have to distribute as a single executeable to be ran directly (from login scripts) and I don't want to start messing with peoples dll's.
The number of people with classic 95 is tiny (possibly non-existance) so I decided that they would simply have to live without the mouse over.
I was just wondering if there was a subtle reason why you had not worked around it youself if it is the only piece of functionality that fails under classic 95?
Its not a major concern, I was just curious if I was missing something.
Thanks for the reply,
Neil

There are other ways to capture the mouse movement, take a look at the button st code you'll see how to do this and it works in all platforms wiht out any modifications;)

CButtonST uses _TrackMouseEvent too, what's the difference?
|
|
|

If you don't want to use a masked bitmap for transparent bitmap, you can load it with:
::LoadImage(AfxGetInstanceHandle(),szID,IMAGE_BITMAP,0,0,LR_LOADMAP3DCOLORS|LR_LOADTRANSPARENT);
This will use the top-left pixel color as the transparent color and map the button color to it.
