Mirek,

I found the problem:
From the main thread and the second thread run refresh ctrl. If resfresh take some time(log ctrl is bigger) than it conflicts!

I have this situation:
From main thread i start a thread for processing file. Like this:

	
	AtomicWrite(converting, 1);
	stop_process = false;
	//SetTimeCallback(-200, THISBACK(UpdateProgress), TIMEID_PROGRESS);
	Thread().Run(THISBACK1(ConvertXmlWorksheetToOracleXslXML, THISBACK(CheckCancel)));
	
	while(AtomicRead(converting)) {
		ProcessEvents();
		GuiSleep(300);
	}
	return stop_process;
}

methods convert file and check cancel like this:

void OracleXmlToXslConverter::ConvertXmlWorksheetToOracleXslXML(Gate3<int64, int64, String>& p_progress){
	String v_error;
	ConvertXmlToXsl(source_file_address, v_error, p_progress);
	AtomicWrite(converting, 0);
}

void OracleXmlToXslConverter::ConvertXmlWorksheetToOracleXslXML(Gate3<int64, int64, String>& p_progress){
	String v_error;
	ConvertXmlToXsl(source_file_address, v_error, p_progress);
	AtomicWrite(converting, 0);
==>>HERE	CtrlLogText.Refresh();
}

function "ConvertXmlToXsl" process file and return log!

If I comment "CtrlLogText.Refresh();" then all works fine!
I can upload this package if is need!

My function converts MS XML Spreadsheet intro XSL-XML layout template for Oracle E-Business Suite XML publisher.

Best Regards, Ion Lupascu (tojocky)

Mirek,

Thank you for reply!

I used RichTextCtrl for show log. If RichTextCtrl data (text) increase more than x bytes size then program prompt error!
Is any limitation for String or RichTextCtrl data?

2GB for String. Hard to say what is RichText limit... but I think at least 200M of characters (depends on formatting).

I think RichTextCtrl (and String) are quite tested by time. But I can fix your problem if I get a testcase:)
