Hello Experts.

I've made some good progress with learning how to interact with an Access database through VB.NET. The attached project includes some useful techniques for populating ComboBoxes with multiple columns using LINQ queries, and leverages Access' ability to generate Queries (which VS calls 'Views') for the purpose of connecting two related tables for populating the ComboBox list items, and any data bound form objects and DataGridViews.

This project uses two tables; one for a list of Players (which I call 'Roster') and one for a list of Teams. The Roster table has a Teams Key that joins to the Teams table which includes the Team Name attribute. I also decided that I wanted to include a picture of every player so Team Captains would have an easier time identifying who's who ("which of you guys is John Doe?"). So it was easy enough to add a new column to the Roster table in Access of type OLE/Object. I then added the code so the image file could be retrieved and attached to the bound PictureBox. That all works good, but since the PictureBox is only a tiny 120x90, I want to be sure the image file is sized correctly so it doesn't bloat the Access table too much.

To that end, I found a nice solution but it was in C#, so I'm not sure if I was able to convert it properly to Visual Basic. But the real head scratcher for me is understanding the concept of an IO.Stream which is how this image resizing solution is rigged. That leads to my real question -- how do I …

Hi,

I am looking at a few different things. I am using ASP.NET 4.0 and VB.NET code-behind.

The main situation is this.

I have a page with an iFrame.  We'll call that Page 1 and the page in the iFrame as Page 2. The page of the iFrame on Page 2 is a URL location is external and that page cannot change.

Page 1 is polling the database running on reload of the page which invokes the Page_Load on the reload. That Page_Load is executing the stored procedure to check certain values in a table. Page 2 (the one in the iFrame) is where certain information is entered and will have a submit button. After a period of time, information from the Page 2 will go into the same table that I am polling on Page 1.

What is going on is every time Page1 reloads (based on like 10 second interval) the data in Page 2 (in the IFrame) is lost.

How can I keep that from happening?

I can think of one way, off the cuff, and that is to use the Page 1 and Page 2 as a frameset. And one Frame (for the Page 1) is doing the polling and reloading... The other frame is doing the Page 2 but in an iFrame.

When the user hits the "Submit" button on the second frameset (Page 2) then break out of the frameset and only have the Page 1.

Break out of the Frameset from the code behind of Page2 with JavaScript like? Or is there another way?

Page.RegisterClientScriptBlock("ResetPage", "<SCRIPT>top.location.href=" + Page1URL + "</SCRIPT>");

Hi,

How can I set a variable in JavaScript on an ASPX page but also have the contents available in the VB.NET code behind? This is for an ASP.NET 4 and VB.NET

I can set the variable in the JavaScript but it's not available in the code behind.

I can set it something like this:

 function SetUserName() {
            var myvar = document.getElementById('<%= TextBox1.ClientID %>').value
            '<%Session("LastName") = "' + myvar + '" %>';
            alert('<%=Session("LastName") %>');
        }

Select all Open in new window

But when I try to get it from the code behind using like an Intermediate window I get like:

Session("LastName")  I like "' + myvar + '"

The alert is above in the javascript is showing the right thing. But that setting it apparently only happening on the ClientSide. How do/can I get it to happen on the client side but also on the server side or can I? Is this where Ajax come into play?

If so, how would something like that be done?

Any information would be greatly appreciated.

Hi Experts,

I have a date picker control.  I have three categories of dates.

1. Menu Available - If menu available for that date then change its color. Which I can do right now.

2. Customer Order available - If Customer order available then change its color to a different color(This web method has a CustID parameter).

3. If the date is a holiday, then disable it.

Thanks in advance.

The user provides my vb.net code with a SQL query that would look like this  for example:

select DISTINCT *from employees a INNER JOIN orders b on b.[Employee ID] = a.ID

I want to find a way to populate the datatable I create in code with the query columns and information but not actually get data. Is there a way to do this? The code also accepts queries from MySQL, MS Access, CSV as well as SQL.

Vehicle (parent class)
Two Properties
Two functionalities or methods
One Event

two Child Classes like Two wheeler and four wheeler
One Property
One Property of vehicle Class
One functionality or method
One functionality or method from vehicle

I have a Tuple List and need to do a search.

Dim strTaxCodeXREF_List As New List(Of Tuple(Of String, String, String))

This list is very rapidly loaded with 200,000 rows of data, from a text file.  Columns are (TaxCode, TaxDescription, TaxRate)

I need to do a search against TaxCode and retrieve the corresponding TaxDescription and TaxRate.
TaxCode is not unique. I realize that I could simply do a loop and check every row. However, I am seeking a more efficient solution.
I considered using a Dictionary Object but unless I am mistaken,  Dictionaries are limited to two columns. Moreover, Dictionaries require a unique key.

I am a novice to VB.Net and would greatly appreciate any suggestions on the best way to efficiently perform the search.

Thanks much...
