Get computer names in the Network

I wanted to get all the computer's names as I was doing a till balancing program, related to a supermarket (POS application). On a report I wanted to filter the daily balance.

Daily balance of all stations and station wise. I thought this might helpful, if I share the code snippet with you.


private List ComputersInNetwork()
{
List computerList= new List();
using (DirectoryEntry root = new DirectoryEntry("WinNT:"))
{
foreach (DirectoryEntry computers in root.Children)
{
foreach (DirectoryEntry computer in computers.Children)
{
if ((computer.Name != "Schema"))
{
computerList.Add(computer.Name);
}
}
}
}
computerList.Add("All");
computerList.Sort();
return list;
}

Happy coding.

Illegal characters in path (XmlDocument.Load())

This occurs due to not understanding the expected parameter type for the XmlDocument.Load("filename") method. This method expect a file name.

Look at the following example, this throw the above error.

eg:
//getting a soap response
string sXml = nc.CurrencyExchangeRatesForWeb();
XmlDocument doc = new XmlDocument();
doc.Load(sXml);

To avoid this error, we can use XmlDocument.LoadXml("string") method, following example shows the solution,

eg:
string sXml = nc.CurrencyExchangeRatesForWeb();
XmlDocument doc = new XmlDocument();
doc.LoadXml(sXml);

Happy coding

Get File Name from path string

I have seen many young developers are struggle with getting
the only the file name from the full path.

Here is a simple code snippet to get the file name.

string path = "C:\\TEMP\\temp.bmp";
string fileName = System.IO.Path.GetFileName(path);

Happy coding.

Cannot evaluate expression because a thread is stopped at a point where garbage collection is impossible, possibly because the code is optimized.

Gridview RowEditing checkbox value

We know if we have manually binds the data then, we can access the checkbox or what ever the control by it's id.
as follows

CheckBox ck = (CheckBox)GridView1.Rows[e.NewEditIndex].Cells[8].FindControl("yourCheckBoxControl");



 



What if you auto bided the data to a gridview,



CheckBox ck = (CheckBox)GridView1.Rows[e.NewEditIndex].Cells[8].Controls[0];
