• Visual Basic StreamReader

  Hello, I’m trying to create a program will supply information for variables from a text file, so that as the possibilities change, a simple text file will need to be amended, rather than rewriting the original code. I am reading about FileStream and StreamReader, which seem like just the ticket. For instance, if I wanted to populate a TextBox with items I wrote in a text file, such as: Tom Mike Jim Jean I threw together a sub like this: ------------------------------ Private Sub Button6_Click( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button6.Click Dim objF ...Show All

• Visual Basic How do I get the cursor's client coordinates? (and more)

  This is a twofold question.  I'm learning VB and I'm trying to make a simple app that will display an image in a form where the user clicks.  To do this, I need to know two things:  First, How do I raise a Paint event As to the cursor's coordinates, the MSDN documentation says to simply reference Cursor.Position to get the screen coordinates, but when I try to access Cursor.Position, VB shows an warning: "Access of shared member, constant member, enum member or nested type through an instance; qualifying expression will not be evaluated".  What is the proper way to get the mouse's client coordinates ...Show All

• Visual Studio 2008 (Pre-release) Delete all records

  How do you delete all records in a table with DLinq. Don't have a list of records to give to .RemoveAll(). Using the DLINQ Table API is currently not the ideal way to delete all the records in the table. The best way right how would be to use the direct SQL. ...Show All

• Visual Studio Team System How do I do a build ?

  I installed VSTS on the weekend, and moved my project over to it. It is all good, but now I am in the office, and I can't connect to my server. I can open my project disconnected from source control, but the build menu is all changed - I can't see how to set a release build, and the build option just crashes ( I assume because it's supposed to run the build task, which is not set up yet ). How can I do a build before I go home, I need to deliver a version today. Thanks It's OK, I found it all.  Forget you even heard the name... FWIW - you need to go into the project properties at the bottom of the Project menu and set the co ...Show All

• Visual Basic VB.NET and a simple game

  Ok quick question about VB.NET. I'm making a very simple BreakOut game in vb.net and I have used PictureBoxes for the bat and the ball, and I have added the physics and collisions etc for the bat and ball and everything and it's fine... next I added a button for one of the game's "bricks"... now the brick has no events and is moderated and controlled by a timer. Is there anyway i can get this timer to, instead of performing code on that specific button, it will perform the code on every button within the form Thanks in advance for the help, and if you need anything clarified please ask! -Javawag   ...Show All

• SQL Server Blocking Transaction

  I have a 3 simple packages get called from master package. First package populates time dimension (stored proc), second one populates transaction type dimension(stored proc) and the final one populates date dimension. I set the TransactionOption = Required in the Master package, every thing else (package & component) set TransactionOption = Supported.

• Visual C# Date Validation on a Databound Textbox

  Friends, I am curious if anyone knows a way to pop a validation messagebox based on what is already taking place in a date bound textbox in Visual Studio 2005. What I mean is this...... Yes, I can write a routine to run through the characters and check if it is a valid date but the textbox (and/or bound dataset ) seems to be doing its own validation. If I do not type in a valid date using a /, ., or -, the form simply will not let me advance to the next record using the navigator, which tells me that the textbox or dataset is doing it's own validation WITHOUT me having to write a whole new method to do it. I even checked an invalid lea ...Show All

• Architecture Entities

  I'm starting the following project: A multi database (SQL Server, Oracle and Firebird) using Winforms in the presentation layer and Web Services in the middle tier. My principal question is about the best way to implement the entities transit between the layers. I'm thinking in this option: a typed dataset based entities without the default adapters created by the VS 2005. Instead I will use a Helper class to factoring the multi database feature and generate the required DataAdapters. I'm free from develop own class for each entity of my system and I could use the benefits of binding and serialization of the datasets. In addition, I wi ...Show All
