问题 I have this function button_Search1_Click to search for comments that match keywords, then display these flagged comments in dataGridView_flaggedComments . Next, if there's any changes on the comboBox_stockIndex , I want the filter to take place i.e. filter the flagged comments in dataGridView_flaggedComments with the Tickers_Ticker_ID of 1 .

Value in the Comments_Date column's cell shows dates in the format of 31/12/2014 12:01 PM , if I choose a date (which is without time portion) from comboBox_stockDates (e.g. 31/12/2014), I want it to filter (and display) all the rows that have 31/12/2014 xx:xx xx . The below code would yield zero result even when the selected date (e.g. 31/12/2014) matches the rows which contain 31/12/2014 xx:xx xx . Any idea what has gone wrong here?

问题 this code below works for filtering JTable until I use english alphabet. It is also not case-sensitive. My goal is to filter white spaces and foreign characters.
