Set ProgressBar properties in a Thread

delegate void SetControlValueCallback(Control oControl, string propName, object propValue);
private void SetControlPropertyValue(Control oControl, string propName, object propValue)
{
if (oControl.InvokeRequired)
{
SetControlValueCallback d = new SetControlValueCallback(SetControlPropertyValue);
oControl.Invoke(d, new object[] { oControl, propName, propValue });
}
else
{
Type t = oControl.GetType();
PropertyInfo[] props = t.GetProperties();
foreach (PropertyInfo p in props)
{
if (p.Name.ToUpper() == propName.ToUpper())
{
p.SetValue(oControl, propValue, null);
}
}
}
}


Thread thread = new Thread(new ThreadStart(Generate));
thread.Name = "Generate";
thread.IsBackground = true;
thread.Start();


The control properties like progressbar properties can be set in Generate Method


SetControlPropertyValue(progressBar1, "Visible", true);
SetControlPropertyValue(progressBar1, "Minimum", 0);
SetControlPropertyValue(progressBar1, "Maximum", dtCompareSets.Rows.Count);

Resolve ConfigurationSettings.AppSetting is absolete warning

While migrating any .Net application from .Net 2003 to .Net 2005 and above we usally get this warning

This warning exists because this method is obsolete, it has been replaced by System.Configuration!System.Configuration.ConfigurationManager.AppSettings

Steps to resolve this issue
1. Add a project reference to System.Configuration.dll.
2. Replace all ConfigurationSettings.AppSettings with ConfigurationManager.AppSettings.

Further if u still get Configuration file app.config or web.config cannot be read

Follow this steps
1. Click on App.config
2. Change build action propert to "Embedded Resource" to "None"

1. ConfigurationManager.Appsettings always returns null

Solution : click on the app.Config file and look at properties window

Setting Build Action to Embedded Resource is causing this problem change this to None this will resolve this problem
