Hi to all!

I have following method with its code:
Qt Code: 
  1. qint16 CApplicationSettings::searchSettingsForIndex(const QString& strHub, const QString& strKey)
  2. {
  3.     if(m_SettingsValues.size()>0)
  4.         for (qint16 iIndex=0; iIndex=m_SettingsValues.size(); iIndex++)
  5.             if(m_SettingsValues.at(iIndex).strHub==strHub)
  6.                 if(m_SettingsValues.at(iIndex).strKey==strKey)
  7.                     return iIndex;    // returns index of found record
  8.  
  9.     return RECORD_NOT_FOUND;    // not found
  10. }
To copy to clipboard, switch view to plain text mode 
Once called, the application crashes with following error:
Qt Code: 
  1. warning: Lowest section in C:\WINDOWS\system32\xpsp2res.dll is .rsrc at 20001000
  2. warning: QLayout: Cannot add null widget to QHBoxLayout/
  3.  
  4. Current language:  auto; currently c++
  5. warning: ASSERT failure in QList<T>::at: "index out of range", file ../../../../Qt/4.3.4/include/QtCore/../../src/corelib/tools/qlist.h, line 391

It is obvious I try to read out of range record, but I simply do not get it why? This code seems perfect to me ... The app crashes in line 5 of method, in the first comparsion.
