Subject: CXTPCommandBarAnimation::RedrawRect
Posted: 08 June 2026 at 4:24pm

Looking at dump files where we crash in AlphaBlendU with a non-null pointer access violation, Claude Code has pointed to CXTPCommandBarAnimation::RedrawRect where lpRect == NULL.

CC thinks RemoveAnimations needs to be called there. I have verified debugging that if I have collapsed groups and click and move over etc. that function is called with a NULL lpRect. It is also called when we programmatically set the popup of a collapsed group with a "find command" tool we have. It is also called when clicking a button on the ribbon.

But still, I never crash. This is "random" in our code base. Can a CJ expert confirm or deny this change is needed:

void CXTPCommandBarAnimation::RedrawRect(LPCRECT lpRect, BOOL bAnimate)
{
    if (lpRect == NULL)
    {
        m_bmpCache.DeleteObject();
        RemoveAnimations();
    }

So far in testing I find nothing bad happening. So, I got that going for me.

One of our most frequently occurring customer crashes has these three CJ apis on the top of the stack with the crash in AlphaBlendU:


>    ToolkitPro2200vc170x64U.dll!CXTPCommandBarAnimation::AlphaBlendU(unsigned char * pDest, unsigned char * pSrcBack, int cx, int cy, unsigned char * pSrc, unsigned char byAlpha) Line 109    C++
     ToolkitPro2200vc170x64U.dll!CXTPCommandBarAnimation::AnimateRect(CClientDC & dc, CXTPCommandBarAnimation::CAnimateInfo * pai) Line 151    C++
     ToolkitPro2200vc170x64U.dll!CXTPCommandBarAnimation::OnAnimate() Line 176    C++


We currently ship the product with V24.2 but V22 is in the customer base. Any chance that is/was part of some crash? The code runs all the time as I move over the ribbon bar so it is difficult to believe there is an issue in CJ itself. But, I ask because I have seen a "crash" fix in the readme file under commandbars but with no details.

Hi Artem,

I wish I knew a way to reproduce the issue. It was random from what I can tell (I just got dump files). We do use skinning and I have been closing the app when we got a deadlock situation as all threads were waiting on objects. I have waited to see if the app would "wake up" and finish but when it is locked that hasn't happened and I just kill it (stop the debugger). I have no ideal if the two are related.

I added the pointer checks too so time will tell if this pops up elsewhere.

Hello,

I've added nullptr check. 
How I can to reproduce your problem?

During shutdown we have experienced crashes in CXTPCommandBarsFrameHook code. The call to GetFramePaintManager has returned a null pointer. In particular, as we shut down the hook's RedrawFrame has been called and the GetFramePaintManager()->DrawFrame line crashed due to the null pointer.

I see that CXTPCommandBarsFrameHook::GetFramePaintManager() can return NULL as can the call to pPaintManager->GetFramePaintManager if it is called.

I also see that many of the calls to GetFramePaintManager in XTPFrameHook.cpp test the returned pointer. Only a few do not and I'm modifying those to do so.

Would be great if a CJ update did the same so I don't have to maintain this change.

Not sure how we get into this as it isn't happening a lot. We do use skinning depending on a user setting for a color theme choice but I run with the skin a lot and haven't crashed. So this change I'm making is a hope so. As in I hope it avoids the crash.

Subject: CSS-Styled SVG Icons Render Black
Posted: 10 December 2025 at 5:37am

Hello,

We are integrating custom SVG icons into our application using Codejock (Xtreme ToolkitPro 24.2) and are encountering an issue:
SVG files that rely on CSS styling (e.g., classes, <style>, and modern SVG structure) are rendered completely black inside Codejock controls. In contrast, the SVGs used in Codejock’s sample projects(Codejock\Xtreme_ToolkitPro\v24.2.0\Samples\Common\svg) render correctly with their intended colors.

Key difference Observed :
Codejock’s SVG uses inline fill attributes and simple path-only SVG 1.1, while our SVG uses CSS styles, classes, <style>, and modern SVG structure. 

I am attaching our SVG files for reference : uploads/9737/Svgs_Rendered_As_Black.zip 

We would appreciate any guidance or help on how to resolve this issue.

Thank you.

Subject: Assertion Occurs When Using SVG Icon with CXTPCont
Posted: 17 November 2025 at 8:04pm

I added a “change font color” button to a CXTPToolBar. The code is as follows:

int PEBookmarkCtrl::OnCreateControl(LPCREATECONTROLSTRUCT lpCreateControl){    switch(lpCreateControl->nID)    {    case ID_BKCTRL_COLOR:        CXTPControlPopupColor* pPopupColor = new CXTPControlPopupColor();        CXTPPopupBar* pColorBar = (CXTPPopupBar*)CXTPPopupToolBar::CreateObject();        pColorBar->GetControls()->Add(new CXTPControlButtonColor(), ID_BKCTRL_COLOR_NONE);        pColorBar->GetControls()->Add(new CXTPControlColorSelector(), ID_BKCTRL_COLORSELECTOR);        pColorBar->GetControls()->Add(new CXTPControlButtonColor(), ID_BKCTRL_COLOR_MORE);        pPopupColor->SetCommandBar(pColorBar);        pColorBar->EnableCustomization(FALSE);        pColorBar->InternalRelease();        lpCreateControl->pControl = pPopupColor;        return TRUE;    }    return FALSE;}

After changing the icon to an SVG, an assertion started occurring.
It happens when CXTPControlPopupColor::SetColor() is called in the ON_UPDATE_COMMAND_UI handler (see attached).
What should I do to fix this?

Hi,

I activated the Frame Theme using m_pRibbonBar->EnableFrameTheme(TRUE), but now my app icon is hidden.

How can I bring it back?

Hi,

Is it possible to remove the section of the ribbon that displays the group names?
