You did. The problem is no the lack of "experts" seeing your question.
The problem is that your question is so broad and requires an answer so large that it won't fit in a few forum posts.
The quality of the answer you get is directly dictated by the quality of your question.

Take out the single quotes from your query string.
make it
SqlCommand cmd = new SqlCommand("select * from " + comboBox1.SelectedItem.ToString(), con);

IMO if you had written the failing SQL statement to the console (or to a log file) you would easily have seen where it went wrong yourself.
PS: if your combobox allows editing, your SQL statement is open for injection attacks, and people could easily delete your tables...

Hi...there is problem in backup of database.Here i m providing the code..
try
{
DateTime Time = DateTime.Now;
int year = Time.Year;
int month = Time.Month;
int day = Time.Day;
int hour = Time.Hour;
int minute = Time.Minute;
int second = Time.Second;
int millisecond = Time.Millisecond;
//Save file to C:\ with the current date as a filename
string path ;
string p = saveFileDialog1.FileName;
path = p + year + "-" + month + "-" + day +
"-" + hour + "-" + minute + "-" + second + "-" + millisecond + ".sql";
StreamWriter file = new StreamWriter(path);
ProcessStartInfo psi = new ProcessStartInfo();
psi.FileName = @"C:\Program Files\MySQL\MySQL Server 5.0\bin\mysqldump.exe";
psi.RedirectStandardInput = false;
psi.RedirectStandardOutput = true;
psi.Arguments = string.Format(@"-u{0} -p{1} -h{2} {3}",
"root", "123456", "localhost", "userdb");
psi.UseShellExecute = false;
Process process = Process.Start(psi);
string output;
output = process.StandardOutput.ReadToEnd();
file.WriteLine(output);
process.WaitForExit();
file.Close();
process.Close();
MessageBox.Show("backup is created");
}
catch (IOException ex)
{
MessageBox.Show("Error , unable to backup!");
}
}
}
so the problem is when pointer reach to this line-
Process process = Process.Start(psi)
then an existing event is automatically called and i dont think that this event has to do anything with it....the event is this..
private void tabControl1_DrawItem(object sender, DrawItemEventArgs e)
{
{
e.Graphics.DrawString("x", e.Font, Brushes.Black, e.Bounds.Right - 15, e.Bounds.Top + 4);
e.Graphics.DrawString(this.tabControl1.TabPages[e.Index].Text, e.Font, Brushes.Black, e.Bounds.Left + 12, e.Bounds.Top + 4);
e.DrawFocusRectangle();
}
}
so because of this i m unable to create a proper backup file...so plz give some suggestion....

The event has nothing to do with it as you stated; it merely redraws a tabitem.
You're catching the output of the application that you're starting.
string output;
output = process.StandardOutput.ReadToEnd();
What does the string "output" contain?
catch (IOException ex)
{
MessageBox.Show("Error , unable to backup!");
}
Does it show this message? Can you check whether the code throws an exception? Change the errorhandler to something similar like below;
catch (IOException ex)
{
if (System.Diagnostics.Debugger.IsAttached())
{
Console.WriteLine(ex.ToString());
}
else
MessageBox.Show("Error , unable to backup!");
}

I consumed a wsdl file in a windows application as webreference. I called a method from the reference.
At runtime, I'm getting the exception "Method CRService.crRequest can not be reflected."
at below line.
CRService cr = new CRService();
Please guide me to solve this exception
|
|
|
|
|
The likeliest problem here is that CRService.crRequest uses a datatype that .NET doesn't recognise (based on the wsdl is imported).

How can we identify which type causes the problem.

I am very sorry. Were you trying to add something useful that would help a novice like myself, or were you trying to prove that you can form complete a sentence. Honestly, I am only looking for constructive help. Nothing else.

I think you responded in the wrong spot. This thread is from a very generic question and the first response, not even from me, was to search google. This isn't even your question. Then a few of us enjoyed a little humor during a Friday workday.
I actually did provide you an answer to one of your questions.

I wrote this small program from an example in the C# book and it compile fine, but gives a path error for the file that I am reading. I created an external file at c:\tempPath
Can someone please advise?
Thanks.
using System;
using System.IO;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApplicationTEST2
{
class Program
{
static void Main(string[] args)
{
string tempPath = Path.GetTempFileName();
string tempPath2 = Path.GetTempFileName();
if (File.Exists(tempPath))
{
byte[] data = File.ReadAllBytes("c:\tempPath");
File.WriteAllBytes(tempPath2, data);
Console.WriteLine("First byte: {0}", data[0]);
Console.WriteLine("Last byte: {0}", data[data.Length]);
Console.WriteLine(data.Length);
}
}
}
}
OUTPUT:
Unhandled Exception: System.ArgumentException: Illegal characters in path.
