I have Text Control in the dialog. After I run app the text (or control static) is blinking from time to time. I set the text in the control like below.How can I remove this effect?

What I have tried:

I tried change the properties, perhaps it should be called from another method.

My OnInitDialog():

CBCGPStatic m_path1Name; 
CFileInfo m_substr1; //it is our class The text control has variable m_pathName1

m_pathName1 = APPLICATION->GetRecentFile(0);
m_substr1.Create(m_pathName1);
m_pathName1 = m_substr1.GetFileRoot();
m_path1Name.SetWindowTextW(m_pathName1);
