I have the following function that combines objects based on their gameScore attribute [code]NOTE the function is in a different class than where I have the lists I'm giving it..I had to set all the game positions blank because it saw an object with the same ID but different position as a different object. I didn't realize that even though I passed in the list ByVal the code deletes the courses on the original list somehow.First I input the origonal list expecting it not to be altered and put the output as a new list.[code]Yet somehow even the last one deletes the gamePosition attribute on listGames BUT *Doesn't* do the sum funtion for them, why is this happening it doesn't make any sense, it shouldn't touch listGames

how to get the DataGridView CellMouseDoubleClick to fire when a user double clicks on a DGV cell.I currently have both DGV.CellMouseClick & DGV.CellMouseDoubleClick implimented in my code.The DGV.CellMouseDoubleClick never fires and the DGV.CellMouseClick always fires. The only exception is when I position the cursor between DGV cells and get the double arrow. If I double click with the double arrow then I get the DGV.CellMouseDoubleClick to fire.I need to take different actions for users RT-Click, RT-Dbl-Click, LT-Click and LT-Dbl-Click.

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?
View 2 RepliesI 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?

I've asked this question before, and so have many before me, i have done extensive research on the topic and stil no help. Maybe this is some kind of secret info. shared only amongst top programmers.

View 2 RepliesI have a large number of MS Access databases that I'm automating to relink tables. However, there is one table that can't be relinked normally as Access says it has too many indexes. A manual work-around is to link to the view in SQL Server (2000/2008) and rename that table.Now, I want to do this programatically (I'm using DAO to relink the tables, which works nicely). I've been looking at CreateTableDef, but I don't know if this is the right way of going about it. I don't want to hardcode 260+ fields that may change (this is the main table from a 3rd party vendor, so I have no control over the fields in this table, or any normalization for that matter, but that's another topic...).Also, 98% of the tables being changed are Access 2000/2003 tables. The other 2% are Access 2007/2010.[code]
View 5 RepliesCurrently I have DataGridView box, clicking generate button fills it with a query from the database.I want the add button to add another row filled using the same query, so far I cannot get it to do it.Current generate button code:
Me.TableAdapter.FillBy1(Me.DataSet.App)
Add button code:
Me.DataSet.App.Rows.Add() - this does add a new empty row
I tried sticking the generate code inside (between add brackets) it but that just did the same thing as the generate code.

General question on linked resources. I just want to clarify what an application does with linked resources. For explanatory purposes lets say that my resources are a bunch of images.

There are 2 ways we can add .vb files.We can add them as a link and choose not to copy. Or we can add them and copy.The way I did it in vb.6 is equivalent with add them as link and choose not to copy.Also what's the point of copying to target folder anyway? I want the original linked file to be updated when I change the file during debuging.

View 3 RepliesOne section of my latest project idea involves linking several form controls to the Google map (distance calculating section), which is area I'm not familiar with.
What I would like to achieve is following: (VB2010) I would like to link two combo boxes on my form to Google map (Start Address and End Address)as well as two labels representing distance & ETA time to Google map (Suggested route, option No.1, highlighted section).
As soon as user select values from combo drop downs on my form, code performs search trough Google web page and return values to my labels on a form. At the same time database would be populated with a same search values (Start Address, End Address, Distance in Km and ETA time)
Link to a web page seems to be a very common request within community members but I did not find anything similar to what I would like to do, so it makes me think that my project idea is going to be" hard bone". I do not need Google web page displayed on my form in a split container or in any other way.
