How to use CheckListBox on an MDI child form in Visual Studio 2005 
Saturday, July 29, 2006, 01:45 AM - CheckListBox
A user reported CheckListBox didn't work with an MDIChild form. Whenever the form was made a child form, the listbox would load, but all entries would appear invisible. The vertical scrollbar showed that the listbox did contain items, but the user just couldn’t see them. If removed the code that made the form a child form, everything would show up properly.


If you want use CheckListBox ActiveX on a MDI child, you must place a panel on the child form, and then place ActiveX control on the panel. Not only our control, but several ActiveX controls have such problem.

Visual Studio 2005 MDI Sample is attached.

How to make the most recent added item visible 
Wednesday, August 24, 2005, 12:19 AM - CheckListBox
One customer asked, "I am using your listcheckbox and want the most recent added item to remain visible, in other words I want the scroll bar to scroll down one automatically. How can I do This?"

To programmatically scroll your CheckListBox, you can use the TopIndex property. This property determines which entry is the first visible entry in the CheckListBox.

To make the first entry visible at the top of the ListBox, use

CheckListBox1.TopIndex = 0

You can show the last entry. Using code like this

CheckListBox1.TopIndex = CheckListBox1.ListCount - 1

will make the last entry visible, but it will be at the bottom of the ListBox, not the top.

CheckListBox ActiveX version 2.6 SP5 is released 
Sunday, June 5, 2005, 03:05 AM - CheckListBox
A maintenance version of CheckListBox, Version 2.6 Service Pack 5, is released.

CheckListBox ActiveX Control provides support for listbox containing checkboxes, which is like the control that is built into Microsoft Word and Excel. In this control, each item's font, color, enabled and checked state can be individually modified. The control also supports 3D look, picture items and custom check mark. This package includes samples written in Visual Basic, Visual Basic .NET, Visual C#, Visual C++, Microsoft Access and Internet Explorer. CheckListBox is also called Check List.

In this version, WordWrap property is implemented. If WordWrap property is set to True, the control will automatically wraps words to the beginning of the next line when necessary. Following is snapshot of WordWrap sample.



FindString and FindStringExact methods are added, so you can easily search items in the listbox.

We also tested Visual Basic .NET, Visual C# and Visual C++ samples in Visual Studio 2005 Beta 2, and modified Prop sample and Color sample to make them compatible with this beta version.

Two small bugs are fixed:
  • Fix the bug that List Box appears without any border if the Appearance property set to claFlat(#10027).
  • Fix the bug that setting ListIndex will cause invalid property array index error in single selection mode(#10028).

    Please download full-feature evaluation version from http://www.zealsoftstudio.com/checklistbox/.

    Registered user can download the upgrade version from http://www.zealsoft.com/upgrade/.

    REALBasic is not so good as expected. 
    Tuesday, March 22, 2005, 10:21 PM - CheckListBox, Color ComboBox
    REAL Software will offer "stranded" Visual Basic (VB) users free upgrades to REALbasic through March 31. I download REALBasic 5.5.5 and got a license key yesterday. I also found a good tutorial. I tested it with CheckListBox activex and Color ComboBox activex control.

    The converter provided by REALBasic can convert most Visual Basic code into REALBasic, but if failed to convert activex control. It simply replaced the activex control wtih a canvas control. I still need to manually modify some code just like using VB.NET upgrade wizard. But the REALBasic's syntax is remarkably different with Vsiual Basic's, especially on ActiveX controls, so I need more time to learn it.

    With my primary test, CheckListBox can be used at design time, but when my program was going to run, the control disappeared without any errors. Color ComboBox seemed all right with REALBasic. I'll test REALBasic later to know why.
