throw new WrongForumException("You are in wrong forum.");

if (question.ToUpper().Contains("URGENT")){
throw new NotYourSlaveException("We are not your slave dud.");

I also had experienced this, so i change the Get[Type]() methods such as GetString(index), GetInt16(index) etc with GetValue(i) or DataReader indexer it self, but it must be checked first if return value is DBNull. In your case replace your code in line that gives error with

KIDYA wrote:

strRow += (string)dr.GetString(i); // Gives error here

if (!Convert.IsDBNull(dr[i]){
strRow +=dr[i].ToString();
}

or

if (!Convert.IsDBNull(dr.GetValue(i)){
strRow +=dr.GetValue(i).ToString();
}

hope it helps

yes it is. 1. create a web service application 2. in a method from your web service call your stored procedure using System.Data.DbCommand inheritance (i.e SqlCommand for SqlServer) by set it's CommandText property with name of your stored procedure, CommandType = CommandType.StoredProcedure and create it's related parameters (see SqlParameter class as sample) 3. Create a windows application (windows form or console) 4. Add Web reference from your web service address to your windows application, usually it will create a class refer to your web service object 5. call the method in step 2 from created web service class in your windows application hope it helps

I will try to resume all answers in the following steps 1. Open file that you want to parse 2. Use StreamReader to read the file 3. Read line using StreamReader.ReadLine(); 4. If Step 3 has data, continue to next step, other wise go to step 9 5. from result in above step replace all unnecessary characters with space, in your sample data replace "==" and '=' to space 6. split result from step 5 using method [yourstring].split in your sample use space as split character 7. post result from step 6 to database 8. repeat step 3 until 7 9. close your StreamReader 10. if there are errors occurred after you doing all steps, ask about them to this forum and read correlated documentations you need happy coding... :)

are you create a centralize controller for keeping that in static method?

yes usually i create static class to hold data that will be accessed in other objects, like "session" in webserver

DataSet is referenced type, as you see in your BLL and PL in finally part you destroy your object (DAL and BLL) : finally {obj = null}, your dataset in PL will be lost reference too. remove finally part of your code. hope it helps

using (SqlServerForm sqlServerForm = new SqlServerForm())
{
if (sqlServerForm.ShowDialog() == DialogResult.OK)
{
Application.Run(new frmMain());
}
}

1. In main entry point use your MainForm in Application.Run(new YourMainForm) 2. In your main form load event call your Sql Server Form Setting with showdialog and verify the settings 3. Close your Sql Server Form Setting. hope it helps
