May 10, 2010I'm trying to find a way to trick the compiler into exposing lines of code where the default "ToString" method of Integers, Longs, Doubles, DateTimes, etc. is being used. These are lines of code that must be reviewd for culture specifics. FxCop does not expose these areas when .ToString is not used explicity in the code.Putting a class in with something like the following freaks it out

Private Declare Function BlockInput Lib "user32" (ByVal FBlock As Long) As Long?
Dec 26, 2009In Visual Studio 2008 I am using :Private Declare Function BlockInput Lib "user32" (ByVal fBlock As Long) As Long To stop input from occuring during a search-replace operation.
BlockInput(True) ' do not allow input during search and destroy
Dim cursorIcon As Cursor
cursorIcon = Cursor
Cursor.Current = Cursors.WaitCursor
Then setting it to false at the end of the operation. It did not work, so I thought maybe it was because I was calling it from a child window, so I created a function in the mainwindow, and ran it like this:
FrmMain.BlockFrmMainInput()With these functions is the Main window:

It did not solve the problem. I thought maybe it was because I was running under the debugger, so I tried compiling and running it debugger-free, but that did not do any better. I am still getting input when I double-click the mouse on either form.

Dataset.clear Method - What Does It Actually Means
May 13, 2009I think I've misused this method and would like to know what it actually does.I 've looked it up on msdn forum and found this
[code...]
What does it mean by removing all the rows in all tables? Is it the datagridview table? When it says "removing", does it mean that it deletes everything?
The reason I misused it is because I thought dataset.clear means it flushes the record held in dataset.
When I click on the add new icon on bindingnavigator, a new form will appear, which allows me to insert data
[code...]
when I close the insert form, the parent form will be activated and datagridview will display the new record I just inserted. I thought the dataset.clear method helped display the new added record but then I realised I could do without the dataset.clear method.
