Auto Scroll in Common Controls

-
This example shows, how to programatically autoscroll WinForm controls TextBox, ListBox, ListView, TreeView and DataGridView. Autoscroll to the end of box or view is useful. For example, in situations when you use one of these components as the output log window. Usually you add the items to the box or view and you want to be sure that the recently added item is visible without the necessary to do it manually. Though it is not difficult to solve this problem, .NET doesn't provide any unified way how to do it. TextBox autoscroll Code: textBox1.SelectionStart = textBox1.Text.Length; textBox1.ScrollToCaret(); ListBox autoscroll Code: listBox1.SelectedIndex = listBox1.Items.Count - 1; listBox1.SelectedIndex = -1; ListView autoscroll Code: listView1.EnsureVisible(listView1.Items.Count - 1); TreeView autoscroll Code: treeView1.Nodes[treeView1.Nodes.Count - 1].EnsureVisible(); DataGridView autoscroll Code: dataGridView1.FirstDisplayedCell = ...

Disable close button on form - C#

-
In one of my projects, I had to implement a form with Close[X] button Hide, so that the user cannot leave the form until it finishes the data processing. From the form designer window in VS.Net 2005, it is possible to hide the Minimize box and Maximize box. But there is no property called Close or CloseBox.

Convert typed library (.tlb) to .net assembly?

-
Sometimes we have to use the legacy code(C, C++) in .Net projects which is provided by third party vendors. Most of the times these guys will provide, equivalent .net framework typed library (.tlb) of that legacy code. Then, how to refer those in our .net projects and make use of functionality provided by it?   Follow the below steps, Keep ".tlb" file which is nothing but legacy typed library Open windows command prompt Go to directory, " C:\Program Files (x86)\Microsoft Visual Studio 8\SDK\v2.0\Bin " or     "C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin". It depends on which version of visual studio you had. Enter the following and execute, TlbImp.exe "E\MyLibrary.tlb" . Here, replace "E:\MyLibrary.tlb" with path to your tlb file. It will import the .net framework type library to assembly.i.e, .dll and it can be found at path "C:\Program Files (x86)\Microsoft Visual Studio 8\SDK\v2.0\Bin" with name ...
