• Windows Forms Custom Control can't be used

  Hi, I've developed a simple control by inheriting from ComboBox. eg public class CatKeyword : ComboBox {} There's hardly any extra code to it. I've done it such that the new Custom Control appears on the 'My App Components' list on the toolbox - just like a real comboBox! It worked when I first created it.

• Visual C++ int CString::find() ignores newline character?

  I have a text file that is of this format: abc def ghi I read this file into a character array and then passed it into a CString.

A temp table #A contains some number of rows (in this case, about 45k rows). 1. Create temp table #B and insert a subset of the rows in #A (in this case, the subset happens to be 100% of #A) 2.
