  Hi, When I open win form app via Vs.Net, I found the main form larger and all controls that it contains will be bigger and gone to other positions.

• pragati22 How to show the caps lock is on balloon warning like Windows

  Does anyone know how I can show that balloon that windows shows when you are trying to logon and your caps lock key is on There are some VB examples out there of how to show balloons, but I need to show one using C# not VB as a warning to users when their caps lock key is on and they are trying to logon to an internal system.

• Xargo CollectionEditor questions Names in left pane

  Hello all, CustomItem is a class which inherits Component. I then created a strongly typed CustomItemCollection which inherits CollectionBase. Next, I wrote a custom editor which inherits from CollectionEditor. It works well except that I can't figure out how to access the (Name) property in the PropertyGrid. I would like to change the names in the left pane away from Class0, Class1, Class2, etc. based on one of the properties in my CustomItem class. Thanks in advance for any ideas and/or suggestions. If your CustomItem has defined a Name property it should already be in the PropertyGrid on the right panel. So the only thing you have to do is to show that name in the left panel. You have to over ...Show All

• Mikey Stevey Form does not refresh if It loses and regains focus

  I have written my first Win Form application in C#, that writes several hundred records to a database. It has a single form with a datagrid and a textbox for displaying status. In the loop I update the text box with the record number being processed: tbxStatus.text = recNo.ToString(); tbxStatus.Refresh(); This works just fine as long as the application has focus and is on top. However if the application loses focus (by minimizing or moving focus to another application), upon regaining focus it seems to freeze (shows an hour glass but no updated status) . If I look at the Windows XP task manager the application shows 'Not Responding', even though I know that the process is still running. (I know that because all the records d ...Show All

• Annihil8 How to add delay among the callings of application, which is related to click on the button.

  Dear all, I met one problem. My scenario is as follows. There is one form1, which contains a tabfolder, and one button embedded in the tabfolder. Their relationship can be expressed as Form1(TabfolderOne(buttonOne)), where brackets stand for "include".

How should I implement it I have some ideas. Howerver, I don't know which way is better, or none of them is better 1. do sth in the "for" loop when ...Show All
