I have a datagrid displayed. I want to be able to show a tool tip on the cells that have info. The info I have the tooltip are the results of a store procedure that I run, and sve the results as a string value. Then pass that value to the tool tip. My strore procedure works properly in SQL. And when I hard code values in my code, it works just fine. I step through the code and the values the SP needs are correct, just the output is Null. My biggest concern is how I'm calling this, under cell formatting.
Private Sub QDGV_CellFormatting(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles QDGV.CellFormatting
If e.Value.ToString.Length = 4 Then

I've created a datagrid and made it read only, I want to double click it and it will open a new form with all the data so I can edit it and press save.
I have a form called New client where you add the name address etc and press save.
I want the fields already on the add client form to fill in the data from the row you double click on the grid.
From what I'm finding, there doesn't appear to be any particular function available to obtain the value from a particular field from a double clicked on row of a datagrid...
So if you wanted to double click on a particular result in a datagrid, then pass one or more of the values of that row, you couldn't?
I was thinking something like this, but of course that doesn't work, any ideas?
Private Sub InventoryDataGridView_CellContentDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles InventoryDataGridView.CellContentDoubleClick Dim invID As String = InventoryDataGridView.CurrentRow(???ParticularField???) End Sub

I don't want any code given I would also post what I have got so far but at the moment I am at work.What I want is to know how to manipultate the datagridview control so when a cell is double clicked a saved html page will load from a database.
Does anyone know if it's possible to skin the tooltip window so it looks like: Attachment 2448.Instead of the yellow box or the balloon like it does now?

I have a situation where I am handling both single & double mouse click events on a form. In both cases something has to be loaded, however when a double click occurs, I do not wish to execute the code attached to the single click event.Is there a way to intercept the mouse click's and check if double or single and then execute the right event appropriately?
I have a htpc project that I am working on. The main program loads dll plugins which are basically other win forms. On each of these forms, including the main program, I use a picturebox (a double buffered picturebox) for the background image and then draw everything on it by hand. Whenever I load the form from the dll and show it, I get a weird flicker. It looks like it is the previously used double buffer. Is there any way to clear the background double buffer before the flicker? Or am I going in the wrong direction?

For greater accuracy I should use a Decimal instead of a Double ( so I've been told ). Why then have Microsoft chosen to use DOUBLE for most of the functions that return a floating point value in the Math Class?
