Hi,
I am trying to save file (with path) extracted using OpenFileDialog to my app.config settings so the file gets loaded automatically on next execution. Can someone help

You want to use "settings", not app.config...
In project, right click the project tree item, and select
Add | New Item... | Settings File. <br />

How do I use the settings. I was able to create settings but the data will be different from user to user.

You can have application-specific settings. You tend to learn things better (and faster) when you work them out on your own instead of asking a question and waiting for an answer.

C#/Asp.net SQL question
=======================
Trying to Delete from SQL database through c# code
SqlDataSource s = (SqlDataSource)SqlDataSource1;
s.DeleteCommand = "Delete FROM Messages WHERE MessageID=id";
s.Delete();
('id' was defined like this
int id = Convert.ToInt32(TextBox1.Text.ToString());)
If I say MessageID = 5 instead of MessageID = id it works fine
(s.DeleteCommand = "Delete FROM Messages WHERE MessageID=5";)
Why can't I use variable instead of a value? Can you please help?
|
|
|
|
|
you probably meant to put the value of the variable into the delete command, not the name of the variable:
s.DeleteCommand = string.Format("Delete FROM Messages WHERE MessageID={0}", id);

Process tmp_process = new Process();
private void Main_Load(object sender, EventArgs e)
{
tmp_process.Exited += new EventHandler(exited_event);
}
private void button1_Click(object sender, EventArgs e)
{
tmp_process.StartInfo.Arguments = @"C:\new folder\abc.ghj";
tmp_process.StartInfo.FileName = @"C:\program.exe";
tmp_process.Start();
}
void exited_event(object sender, EventArgs e)
{
MessageBox.Show("Closed");
}
any solution ? thanks
Edited :
second problem solved after writing this line :
tmp_process.EnableRaisingEvents = true;

Put the arguments inside of quotes \"\" since it contains a space in the file path

I'm running a process in a thread and want to put the results as they happen in a text box on my form. Is that possible? I cant seem to make it work.
|
|
|
|
|
It's possible, you just have to transfer the results to the UI thread before updating the text box. 2 common ways of doing this:
textBox.Invoke((MethodInvoker)delegate()
{
textBox.Text = "here are the results...";
});The other common way and recommended way is to use a BackgroundWorker[^] component. It lets you run work on a background thread and call worker.ReportProgress, which fires an event on the proper thread, allowing you to update your UI in there.

I don't believe the cast to MethodInvoker is necessary.

It is because the parameter type is Delegate. The compiler cannot infer which delegate type you mean when passing in an anonymous method; you'll get a "cannot convert anonymous method to type System.Delegate because it is not a delegate type" compiler error.

I've being using objectDataSources to populate some data controls lately. My data access objects return collections of objects rather than DataTables or DataSets. The inherent problem with this is you can't sort a collection by any column (e.g. if I had an EmployeeCollection filled with Employee objects I couldn't sort by Employee.LastName in one method and then Employee.Id in another). So I set out to create a sortable list I could inherit from and be able to sort my collections.
What I have is below, but the problem I have is that I'm converting my generic variables to strings so that I can compare them. I suppose this works fine as long as I override ToString() on my objects so that it makes sense, but it seems like a bit of a kludge. Does anyone have any other ideas that might work?
using System;
using System.Collections.Generic;
using System.Web.UI.WebControls;
namespace IssueTracker.Business.Collections
{
public class SortableList<T> : List<T>
{
public void SortBy(string sortExpression, SortDirection sortDirection)
{
Sort(delegate(T t1, T t2) { return Compare(t1, t2, sortExpression, sortDirection); });
}
private static int Compare(T t1, T t2, string propertyName, SortDirection sortDirection)
{
object t1Value = t1.GetType().GetProperty(propertyName).GetValue(t1, null);
object t2Value = t2.GetType().GetProperty(propertyName).GetValue(t2, null);
StringComparer comparer = StringComparer.CurrentCulture;
int result = comparer.Compare(t1Value.ToString(), t2Value.ToString());
if (sortDirection == SortDirection.Descending)
result = result*-1;
return result;
}
}
}

I'm not sure what you are trying to do but List<> is already sortable
public class Employee
{
public string FName;
public string LName;
public Employee(string fname, string lname) { FName = fname; LName = lname; }
public static int CompareFirstName(Employee e1, Employee e2)
{ return e1.FName.CompareTo(e2.FName); }
public static int CompareLastName(Employee e1, Employee e2)
{ return e1.LName.CompareTo(e2.LName); }
}
List<Employee> list = new List<Employee>();
list.Add(new Employee("Joe", "Smakatelly"));
list.Add(new Employee("Sue", "Rummy"));
list.Sort(Employee.CompareFirstName);
Console.WriteLine("First Name");
foreach (Employee e in list)
Console.WriteLine("{0} {1}", e.FName, e.LName);
list.Sort(Employee.CompareLastName);
foreach (Employee e in list)
Console.WriteLine("{0} {1}", e.FName, e.LName);

No importa. Mi espan~ol está mucho mas mal.
But, you know the word "café" also exists in English which results in "cybercafé"
Coffee is the drink. A "café" is a place which sells coffee for consumption on the premisis.

i've tried various methods as can be seen, but nothing is helping n the project is due sunday.
this is what i want. a data table, called master, has been connected with my project.
it is a list of employees, and a ballot has to take place for a promotion. if that name would be dismissed, the button would be pressed again to retrieve another name, excluding the one that was chosen before.
i want to display the various attributes of the employee in textboxes. i hav no idea wat is happening anymore, i've been on this project for a week, n i regret i dint come here earlier.
 im very very distressed. pls help me ASAP, pls get that code above right. n tel me how 2 kno if the connection is right.
as u can c, i've made the project so that as soon as the form loads, it tels me that a connection to database has been established. n it does so. but its not retrieving data. if i hav to display the data any other way, i will, but just help me outta this mess!

It would seem that you have committed the cardinal sin of demanding help urgently. If you need help urgently then there are various support options you can pay for. If you want help free then you have to wait until some kind volunteer has the time to assist you.

The best advice I can give you is to start your homework earlier and plan out better what you actually want to do. I find thinking about the task and even following the pseudo-code through on paper often helps to highlight problems in logic.
Maybe you could wait for John Simmons' answer if he sees the desperate request. I'm sure your phrase "n i regret i dint come here earlier." may well be slightly modified once you get his reply.
Also note that the words are "and" not "n", "see" not "c", "you" not "u", "I" not "i".
Your last rambling paragraph does not encourage the reader to continue but merely saps the will of the prospective helper.
I still remember having to write your own code in FORTRAN rather than be a cut and paste merchant being pampered by colour coded Intellisense - ahh proper programming - those were the days
