Windows Forms

You mean something similar to below code? string fileName = "C:\\Images\\2.tif"; Bitmap btm = new Bitmap(fileName); //Perform recognition result = vendor.Reader.AnalyzeField(btm); Where is the initialization-code of your _transferFile member?

? A big code dump. So what? What's the problem?

First, I think you need to add a constructor to 'adrData: public class adrData { public string label { get; set; } public adr ad { get; set; } public para pa { get; set; } // ctor public adrData() { label = ""; ad = new adr(); pa = new para(); } } Then, in code, you can do something like this: adrData newAdrData = new adrData(); newAdrData.ad.r1.name = "Route Name #1"; textBox1.DataBindings.Add("Text", newAdrData, "ad.r1.name"); To bind to a specific instance of 'adrData. Unless you create a new instance of 'ad, within 'adrData, then you never initialize the 'routes: because only creating a new instance of 'adr will initialize the 'routes. ~ “This isn't right; this isn't even wrong."

I found the problem. It is a memory leak by design in the TextBox control. There is a feature of this box that allows you to undo a change. By default it is set to infinite. Every time you update the value in the control whether from the keyboard or from the code behind it adds to this buffer. It can be turned off completely by putting a -1 in the number of values to be buffered. This is well documented in MSDN forums but several years old. Finding the right search key that forces it to go back that far is very difficult. This is an old tread of mine I just ran across and forgot to update it when I found the answer. I hope this will help others when they do a search. So many years of programming I have forgotten more languages than I know.

Perhaps I misunderstood your problem, I thought that it was that the ListBox was not automatically reflecting changes to the underlying DataSource List. The BindingList raises events that would cause the ListBox to update automatically when the List changes. Here is a simple example. New WinForm project with two buttons and two ListBoxes. Clicking Button1 adds items to the underlying lists, but only the ListBox with the BindingList as the DataSource is update. Clicking Button2 tells ListBox1 to Refresh it's data. using System; using System.Collections.Generic; using System.ComponentModel; using System.Text; using System.Windows.Forms; namespace WindowsFormsApplication1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } List<int> L1 = new List<int>(); BindingList<int> L2 = new BindingList<int>(); private void Form1\_Load(object sender, EventArgs e) { L1.Add(1); L1.Add(2); L2.Add(11); L2.Add(22); listBox1.DataSource = L1; listBox2.DataSource = L2; this.button1.Click += new System.EventHandler(this.button1\_Click); this.button2.Click += new System.EventHandler(this.button2\_Click); } private void button1\_Click(object sender, EventArgs e) { L1.Add(3); // adds a value to L1, but listBox1 does not display it until the binding is refresshed L2.Add(33); // adds a value to L2 and listBox2 is automatically refreshed to display it } private void button2\_Click(object sender, EventArgs e) { // tell listBox1 to refresh the data ((CurrencyManager)this.BindingContext\[L1\]).Refresh(); } } }

Re-read what I wrote; the button will be invisible if you hide the container it's in. You cannot click an invisible button. Either put the button somewhere else and have it toggle the Visible property, or put the button somewhere on location (0,0) and resize the control to shrink to the size of the button. Third, best option; throw the button and the control you wish to show/hide on a new usercontrol. Bastard Programmer from Hell :suss: If you can't read my code, try converting it here[^]

I tried all of that months ago before posting the message, even talked to Microsoft. I also investigated graphics card issues - no change. It appears they have changed something inside the Win8 graphics kernel so that part of Aero is built-in and cannot be disabled conventionally. CQ de W5ALT Walt Fair, Jr., P. E.

Did you read this[^]? You'll have to custom draw the tab control yourself to change the color. A guide to posting questions on CodeProject[^] Dave Kreskowiak

That's the way to go. But I do not know the functions provided by the control. Why don't you ask the author - there is a section below his article for taht purposes, isn't it?
