Could someone please tell me how I would go about using this function I'd like to click a button in a form, and by clicking it, my code-generated animation will play on the form. Thanks in advance, Ljubica ...Show All

• .NET Development Error on adding custom section to roaming users configuration

  Hi, I'm actually trying to write a custom configuration section class and use it to write into a roaming users file. I took the base code on MSDN Help, but the example works only with ConfigurationUserLevel.None. In my application I like to use ConfigurationUserLevel.PerUserRoamingAndLocal. In fact all works well, I can build the section object, and can attach it to the configuration, but if I try to set the SectionInformation.ForceSave to true or try to use the Save method on the configuration himself, an exception will be thrown with Message "ConfigurationSection properties cannot be edited when locked". The lock will exactly be done on ad ...Show All

• Windows Forms Multi-threading problem with Windows Forms (possibly SerialPort too)

  I've been having a problem when updating a windows form from a different thread. Data is received on using a SerialPort class which fires the DataReceived event (on a different thread). This thread then calls a method on a form which updates a text box. The code used in the method is just like the sample from the MSDN below, which reroutes the call so that the textbox update is done from the same thread. private void SetText(string text) { // InvokeRequired required compares the thread ID of the // calling thread to the thread ID of the creating thread. // If these threads are different, it returns true. if (this.textBox1.In ...Show All

• SQL Server Date parameter format incorrectly interpreted

  Hi, I am using SQL Server 2005 Reporting Services. I have a report with a Startdate and Enddate parameters setup through the report parameters box.

• Visual Basic Amazing super serious bug..

Dim bTest as Boolean = True If Not bTest Then   Debug.WriteLine("bTest is false") End If And Guess what, the debug line is printed.

• Windows Forms Disabling Buttons until Event has finished/finalised.

  Hi all, I have a Button on a Form that populates a ListView with different ListView Items each time the Button is pressed.

Is there a way I can press the button, then cancel the functionaly (not allow the button to be pressed) of the button, do the processing, when the processing has finished, then enable the button to be pressed again I have tried enabling and disabling the button within the Button ...Show All
