The following line generates an ASSERTion:

------------------------------------
> ToolkitPro1010vc71UD.dll!CXTPFontDC::SetFont(CFont * pFont=0x00000000) Zeile 303 + 0x19 C++
  ToolkitPro1010vc71UD.dll!CXTPFontDC::CXTPFontDC( CDC * pDC=0x00127410, CFont * pFont=0x00000000) Zeile 280 C++
  ToolkitPro1010vc71UD.dll!CXTButtonTheme::DrawBut tonText(CDC * pDC=0x00127410, unsigned int nState=0x00000000, CRect & rcItem={...}, CXTButton * pButton=0x05d28a28) Zeile 210 + 0x25 C++
  ToolkitPro1010vc71UD.dll!CXTButtonTheme::DrawIte m(tagDRAWITEMSTRUCT * lpDIS=0x001270dc, CXTButton * pButton=0x05d28a28) Zeile 493 + 0x1d C++
  ToolkitPro1010vc71UD.dll!CXTButton::DrawItem(tag DRAWITEMSTRUCT * lpDIS=0x001270dc) Zeile 156 + 0x29 C++
------------------------------------

It is the first ASSERT in the following function:

-------------------------------------
void CXTPFontDC::SetFont(CFont* pFont)
{
ASSERT(pFont);
ASSERT(m_pDC);
if(m_pDC && pFont)
{
CFont* pFontPrev = m_pDC->SelectObject(pFont);
if(!m_pOldFont && pFontPrev)
{
m_pOldFont = pFontPrev;
}
}
}
-------------------------------------

Could you tell me how to avoid this?

Thanks
Uwe

Hello,

It just mean that CButton::GetFont returns NULL.

Just create some font and apply it to button.

Well, again doing unnecessary modifications .

I really love your library, but I do hate that lots of extra-work that I have to perform after every version-update.

How can I sell this to my customers that I have to spend hours again, just after updating a GUI-library...
