Implement AddHandler For A Form Or Say Something Like Frm = Application.OpenForms.SelectedForm?
Aug 4, 2010
I have ran into a slight problem and I have not met this issue before today.If I create a Form at run-time with a Button on one Form using a LinearGradientBrushhow can I make the Form maintain the gradient when it is Maximized for every Form that is generated?urrently, if you create 2 Forms using the code below, select the 1st Form created and Maximize it, you will see the problem.This problem does not exst for the currently generated Form however. :-)Would I need to maintain parallel Lists Of Forms or / and LinearGradientBrushes or / and ClientRectangles?
Option Strict On
Imports System.Drawing.Drawing2D
Public Class Form1

I have a module that handles adding controls and populating values on a form. One of the controls is a button (there can be many) which acts as a lookup. For some reason, when I click the Button, it winds up in the btnLookup_Click event and displays the various messages, but it does not update the label (labLookup) text on the form. Am I missing something?

I was wondering how to implement a custom character set for use by an application, i.e. hex bytes that are read by the program then converted and displayed in the window. If this requires first converting the bytes in a file to an already implemented character set, I'm cool with it - I'll go with whatever works or works best. I'm writing with VB.NET 2010, and running Windows 7 Home Premium x64, by the way.

I am trying to implement image caching for a web application and I found some code on the Internet that implements an HttpHandler that does this. The code was in C# and since my web app is written in VB, I decided to convert the code to VB. I managed to convert everything except the following code (in bold):
public class FileExtensionCollection : ConfigurationElementCollection
{
public override ConfigurationElementCollectionType CollectionType
{
[CODE]...
From what I can understand, the two properties above provide a way to access the FileExtension collection either using an integer or a string index. My problem is that I do not know how to convert this in VB.

I am upgrading from Visual Studio 2003 to Visual Studio 2008. ow I should upgrade my project.My project is in Visual Basic.Net, and using an Access 2003 Database. I have four datasets, MainDataSet (for the main data tables) LookupDataSet (for lookup tables States, Countries, Colors, etc) OneFormDataSet (data used on only one form) and ReportsDataSet (data used for reports).I have one form "OleDbAdpatForm.vb", that has all the OleDbDataAdpaters for my project. It also has the DataSets and the OleDbConnection.I have public functions that enable me to load the data tables.
I have a LoadTable function when I can pass a column and a value, and the SQL select command is updated with a WHERE or HAVING, so only the requested data is selected. I also can pass the whole "WHERE ..." part of the SQL select command, so I can have multiple parameters in the SELECT command.On my other forms, I have copies of the DataSets, so I can design grids/controls. In the form_Load events, I manually bind the controls to DataSets and tables in located "OleDbAdpatForm.vb", so all forms are using the same data tables, and changes made to data in one form are reflected in data in other forms.The VS 2008's DataSources, BindingSources and TableAdapters seem much easier to use. how I should implement the new data features in my application?

I'm trying to implement an Owner-drawn ListView in my application using the code available at this MSDN article, however I've encountered several issues.First of all, the double-click event only fires when the mouse is over the text in the first column of any ListViewItem. I'd prefer to keep the manual, timer-based, double-click detection routine as a last resort if possible.Second, when the ListView is scrolled sideways, clicking an item won't select it anymore.

I'm fairly new to VB programming. I have a control which is mounted within a form. I need to implement a callback, so that the control can make the parent form do something. My plan was to create a MustInherit class with MustOverride methods, and make the form inherit the MustInherit class. However, Visual Basic tells me that the form cannot inherit more than one class, which means that it can either inherit my MustInherit class, or System.Windows.Forms.Form, but not both.[code]...
