VS 2010 - Trying To Build Button To List All Tables In Database
Oct 27, 2011
I am trying to create a button on a form that will open a connection to a database and list all the tables in the database inside a listbox. Everything I have read indicates I can associate a single table to a form, and have no idea how to:
a. Create code for the button to access all the tables in the database.
b. Display that list in a list box.
The text that I am using is murach's ADO.NET 3 database programming with VB2010, and I am less that thrilled with it.

I've been into programming, I've landed a job with a local company, the entire project the gentleman is paying me to do is incredibly easy, with one hitch, the original project I'm converting is built using access databases, for efficiency, and easier online transfer, I'm wanting to switch to using an SQL database, I've got plenty of experience inserting, modifying, and controlling an access database, but where should I start to learn how to essentially set up, create tables, and modify data within an SQL database?

I am using VS2008 and SQLite. I have created a database and several tables and am attempting to populate the tables with data from arrays.
The following code (example) works fine but stops after it inserts 30 to 50 records. I am running the VB code in debug mode and when it stops, I press pause to see where it is. It stops on "SQLcommand.ExecuteNonQuery()" and when I press continue (F5) it will insert another 30 to 50 records.
I do not get an error message. Is this a timeout issue? How do I keep the loop running to the end of the array?
Following is example code.
Dim
SQLconnect As New SQLite.SQLiteConnection()
Dim SQLcommand As SQLiteCommand
CODE:.....................

In VS 2008, VB.Net, I am successful connecting to a local SQL Server (version 8) and seeing all tables/views/procedures in Server Explorer. The local OS is Win XP Pro SP3. I created an ODBC data source to a remote SQL server (also version 8) with a database of the same structure as the local one. The connection tests out ok. The remote computer runs Windows Server 2000 SP4. In the VS 2008 Server Explorer I add this ODBC source. When I click on the plus-signs to expand items, neither the tables nor the views show anything, whereas the full list of procedures appears. Is it the old SQL Server version? Is it the old Server OS version? Something else alltogether?

This is what I'm sure will be the first of many noob-ish questions from yours truly... I'm studying as a mature student for a Computing Degree (encompassing web design, hardware, programming and systems analysis). The programming seems to be my weak spot this year. I enjoyed C++ last year, doing basic console applications, but progamming visually with VB in Visual Studio 2008 I'm struggling!

I'd like for my application to have a listbox displaying all users currently connected to my access database stored on a server. Also, it would be nice at startup for a message box to pop up saying something like "Other employees are currently using this application. To view active users go to..."

So when i build or click debug on my program. No errors come up and its smooth. So i decide to publish my programme. However. I come up with a bunch of errors during the publishing.
Here they are:Error 1 Cannot publish because a project failed to build. 1 1 Simple CALC
Error 2 Unable to copy file "binReleaseSimple CALC.exe.manifest" to "binReleaseapp.publishApplication FilesSimple CALC_1_0_0_0Simple CALC.exe.manifest".

I want to build a recent files list into my program.
The hiearchy I currently have is "MenuStrip>File>Recent Files>File1".
I have a function which saves the files and opens them. It also stores the file name and file path in sperate variables:
CODE:
I would be able to change the text property of the File1 (File1ToolStripItem) to the SaveFileName easily, but how would I make it so that when you click the File1 (File1ToolStripItem) it opens the Savefile file?
I would also need the program to save this list so when I open the program again they are still there.

Im trying to build a list of id's in a textbox. Which works fine in IE and Firefox but not in chrome.
The list that is created is using String.fromCharCode(20) to separate the values. (im using this as the values could be any character so I need to use non writable characters like this and 17)
What happens in Chrome is it seems to remove anything (and including) from the non writable character onwards so if I had
"432@5033"
where @ = the non writable character then it would output "423"
any ideas why chrome has this behaviour!

I'd like to build a class where I always have a button at the bottom of a form.Then when I drag and drop the button, It has to make a copy of that button called "button1", if I drag and drop the button again I'll have another button called "button2" and so on.But If I drag and drop the "button1" or "button2" they shouldn't duplicate as the original. And this is the problem I can't sort out.
This is my class:
Imports System.Windows.Forms
Imports System.Drawing
Public Class frmTablesEditor

I have just started to learn how to use SMO in some cases. Below is some code I found from a site to list the servers and databases for each. What I would like to do is go a step further and list all of the databases and stored procedures in their own listboxes when I select a database. I would like to not include the system ones or at least have a checkbox to decide to include them or not. I searched and could not find how to do this.
Here is the code I have so far:
Imports Microsoft.SqlServer
Imports Microsoft.SqlServer.Server
Imports Microsoft.SqlServer.Management

I'm trying to develop some AI code for a game I'm creating. I have a list of x,y coords and I need help figuring out what I can use/do to build the shortest path between any 2 points in this list. I would like to build a function that I can pass a list of valid X,Y coords to use when generating the path, start point, end point, and have it return a list of points, which would be the shortest path between the start and end point, using the list of points supplied. I have looked at A* and Dijkstra's, but am having problems implementing the algs in code, as all this seems graph based.
