• Windows Forms DataGridView in windows application

  Hey all I"m new to c# win app, eventhough I wrote some projects for asp.net using c#. My question is about DataGridView. I have added this control to my application and binded it to my access database. I run my application, added some rows to the grid and made some modifications to existing rows but when I exit my program the changes and addition of the new rows is not saved in my access database. How do I make these changes saved  Is there any "autosave changes" property :) Thanks in adavance :) in the dataset designer, select the tableadapter and in its properties, there are the update/insert/delete commands. Create these commands :-) once done, then whenever you are going to ...Show All

• Visual C# Creating and Displaying graphs and charts in C#

  I was wondering if there were any prebuilt chartting functions in VS2005 or the .NET framework as a whole Or would I be required to purchase one of the many 3rd party tools out there If the latter is the case, have you got any ideas for a quality, clear-display, student-friendly version. Thanks. Hello I am quite new to C# etc.. so I don't know if there is any functionality built in VS2005 . I used a trial version of software from www.gigasoft.com . I proved my application then bought the software. It looks good, easy to use and wasn't as expensive as some of the others that I looked at. After 30 days of use it displays a message in the centre of the graph but can still be us ...Show All

  Hi, I am working on a form (details) and I need my form to allow to search on some char fields. I have a button next to the field users can search.

• Game Technologies: DirectX, XNA, XACT, etc. Post-Processing glow shader

  I'm trying to get the Glow shader technique discussed in a Gamasutra article (http://www.gamasutra.com/features/20040526/james_pfv.htm) implemented in my XNA project but am struggling with certain aspects of it. The blur of the scene takes place in two separate passes, one for each axis. So when you do the horizontal blur pass, you pass it your scene which you've rendered to a RenderTarget2D. Then for the vertical blur pass which follows, you have to pass it the resulting texture from the previous pass. This is where I don't really understand anymore... what is the proper way to set this up so that you can extract the results of the first pass and give it to the second pass when you already have an Effect activated ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Best way to learn

  What is going to be the best way to learn XNA I have to say I am not used to "new" technologies. My experience comes from looking up tutorials and then following them and expanding off of them. However, with XNA this is brand new and I hope to be create the tools. Here in lies(sp ) problem I have no idea how to learn something without an abundance of tutorials. XNA has gotten me real excited and I can't wait to get my hands on it and maybe become one of the first people to really adobt and get into the XNA community. Any help would be greatly appreciated. Thank you, Buddy Lindsey Since there won't be a lot of tutorials out there this soon -- the best way to learn will probabily be via the demos like Space Wars that are goi ...Show All

• SQL Server I need help with a SQL Query

  I know that there's a lot of you out there that are really good at Sql Queries. Hopefully, one of you will have pity on me and clue me in. I am working with a Visual Studio 2005.net VB application accessing SQLServer 2005 and SQLServer Express databases. I am using a sql query with ado.net data adapter to return data to a grid bound to the data adapter. My problem is that there is data in the SQL table stored as Bigint data types, that I need to divide by another integer and return as a double precision number. For example, part of the Sql Statement looks like: " InvStock.QuantitySold / NumPeriods AS 'AvgUnitsSold', " It works except for the fact that it returns an integer and truncates the decimal points.

• .NET Development Joined tables, update database with many rows, What is Best Practice?

  I have 3 tables(A, B, and C): A and B have identity fields and C is an associative table with each row referencing back to the identity of A and B. To better describe the tables, A will represents objects, B will represent predefined items the object can have, and C will contain any object/item relationship. I will then have a data grid displaying a handful of objects and the items that could be set. Items already configured for an object will display with a check box, and the rest will be unchecked. When a new association is set, a row will be inserted into table C. When an association is un-set, the row will be deleted from table C. Let's say the situation is like this: initially one object in A has 20 items set, and another object has n ...Show All
