View 5 RepliesI am trying to read a multilined textBox line by line into a List<String> but with the code below the compiler says that "'System.Environment' does not contain a definition for 'Newline'
[Code]....
How do I just get the first line of a multiline textbox? Either that or delete everything after "<br/>"? I tried something like this but it doesn't work:
MyTextBox.Text.Replace("<br/> + '%'", "")
If I have a text file like:
123, joe blow, USA
Where the first values represent:
USERID, NAME, COUNTRY
If my file has 5000 rows, could I update a particular row somehow using C#?
Can u tell me how to read textfile from 15line or from particular line that means i have to ignore first 15 lines of textfile and i should start from 16th line.

View 2 RepliesI'm trying to execute a .bat file in my web page when a user clicks a button. The normal command I would run in the command window is as follows. abc.bat 1 Where 1 is project number which is dynamically assigned according to the scenario in the program. Also the .bat file is inside the folder D:Test1. My code looks like this.....
void CreateProjectData( string strProjectId)
{
System.Diagnostics.Process newProcess = new System.Diagnostics.Process();
newProcess.StartInfo.UseShellExecute = false;
newProcess.StartInfo.FileName = @"D:Test1abc.bat" ;
newProcess.StartInfo.Arguments = "abc.bat " +strProjectId;
newProcess.StartInfo.CreateNoWindow = true;
newProcess.StartInfo.RedirectStandardInput = true;
newProcess.Start();
newProcess.Close();
}
When I run the .bat file the data should be generated for project and stored in a database. When I run this in command line it works fine. But when I run the above code in the asp.net web page it executes without any errors but does not store any values in the database. Have I defined the project name, arguments correctly in the above scenario?
