Question

Hi, I am creating resource file at run time through code its creating and displaying in resource folder but not showing in solution. But When i do it manually as add  existing item, then it was working. Please give me the solution.

public void LaguageCulture(string languageid) 
{ 
try 
{ 
SqlParameter[] param = new SqlParameter[1]; 
param[0] = new SqlParameter("@lagid", languageid); 
//languageid =3 
var dsResources = SqlHelper.ExecuteDataset(_objSqlConnection, "sproc_GetResourceNames", param); 
string culturecode = string.Empty; 
if (dsResources.Tables[1].Rows.Count > 0) 
{ 
culturecode = dsResources.Tables[1].Rows[0][0].ToString(); 
} 
FileInfo file = new FileInfo(System.Windows.Forms.Application.StartupPath.Replace("\\bin\\Debug", "") + "\\Resources\\EnglishResource." + culturecode + ".resx"); // Culture code is en-US 
if (!file.Exists) 
{ 
var resx = new ResXResourceWriter(System.Windows.Forms.Application.StartupPath.Replace("\\bin\\Debug", "") + "\\Resources\\EnglishResource." + culturecode + ".resx"); 
if (dsResources.Tables[0].Rows.Count > 0) 
{ 
for (var i = 0; i < dsResources.Tables[0].Rows.Count; i++) 
{ 
resx.AddResource(dsResources.Tables[0].Rows["ResourceName"].ToString(), dsResources.Tables[0].Rows["ResourceValue"].ToString()); 
} 
} 
resx.Generate(); 
//Application.Current.Resources.Add(culturecode + ".resx", resx); 
resx.Close(); 
} 
System.Threading.Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(culturecode); 
System.Threading.Thread.CurrentThread.CurrentUICulture = CultureInfo.CreateSpecificCulture(culturecode); 
} 
catch (Exception) 
{ 
throw; 
} 
}
