• Visual Studio VS 2005 IDE problem

  I am having a problem with the properties page of all my VS 2005 projects. I can modify all the properties except "Application". When I try to look at this property page, I get the following error: An error occurred trying to load the page. Exception has been thrown by the target of an invocation.

• Visual Studio Express Editions releasing resources question

  Hi, i'm moving an Image object around with the MouseMove event,  and I have a Graphics object which draws the image in a Rectangle object.  Do I need to release resources - such as the dispose() method My pc crashed a couple of times recently, and I wondered if this had anything to do with it.    Hi again, here is the main part of the code - ('pic' is the Image object, picX and picY are just int variables for the Image location, rect is Rectangle object) private void Form1_MouseMove( object sender, MouseEventArgs e) { if (e.Button == MouseButtons .Left) && CanMove == true ) { rect.X = e.X - picX; rect.Y = e.Y - picY; rect.Width = pic.Widt ...Show All

• .NET Development Updating a Table Adapter

  Updating Data from a table Adapter Honestly I do not understand why I need to write code to update a databse and why it stores it localy. I'd simply rather the system update the individual row after it is scrolled off of. In either case since I guess I can't do that. Here is some code in a button on a form Try ItemsTableAdapter.Update( NewCreationsDataSet1.Items) LineCodeTableAdapter.Update( NewCreationsDataSet1.LineCode) Catch ex As Exception MsgBox(ex.Message) End Try I get an error stating "Update Requires a Valid Update Command when passed a dataRow collection with modified rows" Do I need to include ...Show All

• Windows Forms Appending in datatable

  Hi, I have a table in database in which values only get inserted and no deletion or updation takes place. Each row has a time stamp. In my application I grab the table at start up and store it in a datatable and then I periodically go to the database and get all the values again and repopulate the datatable. Obviously, this is not an efficient way as I am grabbing the same rows again and again plus the new rows. I can modify my sql to get only newly inserted rows using the time stamp but how do I append those new rows in my existing datable such that it does not lose the rows already added The updation takes place ever minute and typically involves close to 50 rows. I am using 1.1 Thanks, I gu ...Show All

• SQL Server MSSQLSERVER login failed for user 'MACHINE\user'. [CLIENT: <local machine>]

• Visual Studio 2008 (Pre-release) net.p2p

  Hi folks - i've been working in some detail through the WCF hands on book and recently the P2P support caught my attention as it directly relates to something i have been wanting to do for a while and WCF seems to save me a heck of a lot of time. However, I am not overly familiar with the net.p2p scheme, and from what i have read i have some questions. In the sample (and common in my scenario), there is one (or more) central hubs - that is, it's not a pure P2P network (some hubs, many nodes and X nodes are tied to any given single hub). Although the number of clients may be many, there will be a number of core hubs. Now, from my understanding (and perhaps this is just how the sample implements it), each message that is generated i ...Show All

• .NET Development Suggestion: Overload TryParse to accept defaults

  Hello- Most simple types (bool, int, double, etc) support a static TryParse function that will take a string, and a typed variable to try to parse that string into. It would be handy if there was a second overload of this TryParse function in each case that would also take a default value. Here's how it currently looks: bool foo; if (!bool.TryParse("true", out foo)) foo = true; Here's how it could look: bool foo; bool.TryParse("true", out foo, true); Thanks for the consideration, Eric D'oh.
