View 2 RepliesI have recently taken a liking to programming, and have programmed a few games in C#,my friend has asked me to program an application for him to use in his shop. But I have no idea of what language is best suitable?
View 8 RepliesI avidly create games in VB.net. Being a hobby programmer I give my games away for free. Since I'm a hobbiest without formal training I do try and educate myself on proper programming principles and follow them when programming such as OOP. There are however some things I have obviously missed being self-taught that perhaps I would know if I were formally educated. Once such issue that has really been my bane is how different classes (from now on referred to as objects) 'know' about each other WITHOUT programming specific interaction.
Okay imagine this, you have a space game and the following objects
[CODE]...............
Now each one of these objects has a Health, X,Y and Z private members and properties that are all inherited from clsSpaceEntity for argument sake. Now one way of programming collision between them would be to code out the following logic in the main game loop
[CODE].........................
Now this might seam okay if your talking about the simple example above but some of my games have tens or even HUNDREDS of objects that interact in this basic way. Is there a way in OOP to do the following... for each thing that inherits from clsSpaceEntity check against every other object that inherits this type (except itself) and if they collide then reduce health next? This sort of ability for a type of objects/class or whatever to be 'aware' of another and how they are the same/different and interact would save me tonnes and tonnes and TONNES of coding.
I have gridview binded from database..
I have following code:

{
BindGrid();
}
Now, I have checkBox and drop-down inside the gridView, When user selects some rows from checkboxes and clicks on Update Button, Page_Load event fires and calls BindGrid(); method and selected rows should get hidden. How can I retain checkbox values after the page load event.

I am using vs2005 with access db. I am retrieving a tables data thru datagridview using an access query. The table i am calling is contains "ID" of something and I convert it thru the query and show it as names for the sake of my users.
My problem is how to store again the related "ID" s after they alter the datagridview cells? (i.e:the retrieved table contains only id's of customers and i showned the users as names, after they are editing how can i convert the user name as "ID" because the field is Long Integer foreign key field) Or otherwise how can i show the datagridview partuclar cell value as combobox style?

I have a datagridview bound to a bindingsource. Two of the columns contain values that link to the primary keys in other tables.

View 2 RepliesI have a simple "two-tables" database (SQL EXpress) and a very simple application (VB 2008 Express). The two tables are customer and order and their structures are:
customer(IDcustomer, LastName, FirstName) IDcustomer=primary key orders(IDord, Number, Description, IDcust)
IDord=primary key the tables are related (IDcustomer-->ID cust)
In VB2008 environment I create a dataset, by means of Data Source Configuration Wizard, which encompass both customer and order tables (xsd file). By opening xsd file I set the relationship in the following manner:
"Both relation and foreign key constraint"
Update Rule = Cascade
Delete Rule = Cascade
In my form I show customer table in detail-mode and orders table in datagridview-mode. Two Fill method are created in the Load event and they work correctly.In "CustomerTableAdapter" I create, with QueryBuilder, a search query (say LastName query) and I write the following code:
