Thank you! I did solve the problem as Tony said. But could you tell me why this happen? Why I have to assign QByteArray to another variable? And why only the content is wrong?

Hi Cheng, You didn't show how the html variable was used? Are you sure that the html pointer is valid? I suggest: QByteArray ba = webView->page()->mainFrame()->toHtml().toUtf8(); const char *html = ba.constData();... In your original code, the temporary string and byte array were being destroyed after that statement, causing a dangling pointer in html. Even if it looked valid immediately after, subsequent allocations would have made the area appear corrupt. By keeping a reference to the temporary, you ensure that it will be valid for the whole block. Tony.
