Hi All,
I have a file to send to client rtu. I want to display progress bar while sending file. How it should be implemented in windows form in c#.
|
|
|
|

Well, the progress bar should run on another thread. I assume you get some sort of callback as the file is sent to tell you how much has been sent ?

public void GetCookie()
{
string subkeyName,subkeyValue;
string str = null;
str = Request.QueryString["productid"];
Addtocart.Value = str;
Addtocart.Expires = DateTime.Now.AddDays(1);
Response.Cookies.Add(Addtocart);
for (int i = 0; i < Request.Cookies.Count; i++)
{
AppCookie = Request.Cookies[i];
output.Append("Name = " + AppCookie.Name + "
");
if (AppCookie.HasKeys)
{
for (int j = 0; j < AppCookie.Values.Count; j++)
{
subkeyName = Server.HtmlEncode(AppCookie.Values.AllKeys[j]);
subkeyValue = Server.HtmlEncode(AppCookie.Values[j]);
output.Append("Subkey name = " + subkeyName + "
");
output.Append("Subkey value = " + subkeyValue +
"
");
}
}
else
{
output.Append("Value = " + Server.HtmlEncode(AppCookie.Value) +
"
");
}
}
CacheMsg.Text = output.ToString();
}
Through above coding we try to store more than two cookies but we didn't achieved.....so is there any way to store more then two cookies

First of all which Framework did you used ? Does the client system having the same framework?
Does all dll present in the Client System?
Try to build a setup project, Add all dependency with the setup and then install it on client system then try.
cheers,

Hi all,
I have HTML code like: "". how can I get the final local path that this web handler generated or other methods to get a reference to the final image?
Thanks,

You can't find out the path on the server. If you're running this code on your server, then you should be in the ASP.NET forum.

Dear All,
I had the following code tested in my test environment, it works fine in my test environment
private bool CheckRcvFileLocation(string rcvLocation, ForeignSystem foreignSystem)
{
Uri uri1 = new Uri(rcvLocation);
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(uri1);
request.Credentials = foreignSystem.NetworkCredential;
request.Method = "HEAD";
HttpWebResponse response = null;
try
{
System.Console.WriteLine("test2");
if (request == null)
{
System.Console.WriteLine("Test2a");
}
else
{
System.Console.WriteLine("Test2b");
}
response = (HttpWebResponse)request.GetResponse();
System.Console.WriteLine("Test3");
return (response.StatusCode != HttpStatusCode.NotFound);
}
catch (WebException e)
{
response = (HttpWebResponse)e.Response;
if (response.StatusCode == HttpStatusCode.NotFound)
return false;
else
throw;
}
finally
{
if (response != null)
response.Close();
}
}
however when I put it into the real world, the "Test3" never gets executed, instead it returns me "Object reference not set to an instance of an object" as soon as the code goes to "response = (HttpWebResponse)request.GetResponse();"
Are there any settings that i need to aware to get these codes working in production environment?
regards
Andie

Any news when LINQ be able to talk to Oracle/MySQL/Sybase ...? I hear thus far it's very much a M$ specific...
(And what do you think it will do to NHibernate when it starts supporting other db?)

Hi everyone. I'm new here and new to using C# coding as well so any help would be greatly apprectiated! I am trying to build my program but this message keeps popping up: Operator '||' cannot be applied to operands of type 'bool' and 'string'
I have tried everything that I know. Please help! The code is below:
using System;
namespace Program13
{
class StateAbbreviations
{
public static void Main( )
{
string stateabb;
Console.WriteLine("Enter all of the following state abbreviations: NC, AL, GA, FL, OH");
stateabb = Console.ReadLine();
Console.WriteLine("\n");
if (stateabb == "NC" || "nc")
Console.WriteLine("North Carolina");
else if (stateabb == "AL" || "al")
Console.WriteLine("Alabama");
else if (stateabb == "GA" || "ga")
Console.WriteLine("Georgia");
else if (stateabb == "FL" || "fl")
Console.WriteLine("Florida");
else if (stateabb == "OH" || "oh")
Console.WriteLine("Ohio");
else Console.WriteLine("Not one of the selected states");
}
}
}

Hi,
try if (stateabb == "NC" || stateabb == "nc")
I advise you buy and study a tutorial book on C#, any book will do you good.
|
|
|
|
|
Oh my gosh! Thank you so much. Worked like a charm. I forgot about that haha.
|
|
|
|

Why don't you actually read the error message and check against your code?
it said "Operator '||' cannot be applied to operands of type 'bool' and 'string'" which is what you had, an || operator in between a bool and a string.
|
|
|
|
|
I know. Like I said, I am very VERY new to this so I am getting used to all these new terms. I am kinda getting the hang of it though.
|
|
|
|

So 'Nc' isn't a valid entry, is it (of course doesn't make sense discriminating such a bad way 'Carolina'...)?
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

May I suggest you use a HashSet?
System.Collections.Generic.HashSet<string> StateAbbs =
new System.Collections.Generic.HashSet<string>() ;
StateAbbs.Add ( "NC" ) ;
...
if ( StateAbbs.Contains ( stateabb ) ) ...
Or something like that, perhaps with a case-insensitive comparer.

Hi everyBody,

I am having a strange issue with reading from Excel with C#
Here is my code:
string excelConnectionString = string.Format("Provider=Microsoft.Jet.OLEDB.4.0; data source={0}; Extended Properties=Excel 8.0;", txtExcel.Text);
OleDbConnection con = new OleDbConnection(excelConnectionString);
con.Open();
OleDbDataAdapter da = new OleDbDataAdapter("select * from ["+ txtFY.Text +"$]", con);
fy.Text = txtFY.Text;
DataTable dt = new DataTable();
da.Fill(dt);
con.Close();
dataGridView1.DataSource = dt;
dataGridView1.Refresh();
Now it works.. its just some columns that have information in the "actual" excel sheet doesn't appear in the data grid view..
Example:
Here is a column (Serial Column):
136WFW7552
136WFW7556
136WFW7494
136WFW7553
136WFW7492
70101135
71000640
70202250
70101234
70101230
Now when the numbers go from 136WFW7492 to 70101135, it doesn't put the 70101135 numbers in the datagridview... I've removed formatting from the workboot and everything.. I'm confused

What data/columns are in the raw DataTable? Is it what is to be expected?
Try putting HDR=Yes; in your connections string. I can't remember off-hand what the default is.
Edit:
This article pretty much sums it up. Reading and Writing Excel using OLEDB[^]

I've tried that document and it doesn't seem to work.. Any other ideas?

There's always the alternative way of Opening the file itself. Have a look at this example[^]
Also have a look at this: Opening and Navigating Excel with C#[^]
It's not ideal but it's a work around.

Im not sure if it will work or not but you may be able to select the columns using GetOleDbSchemaTable().
Then use those columns in the select query,
private string[] _GetColumnsFromWorkseet(string sheetname, out string errorMessage)
{
try
{
List<string> ls = new List<string>();
DataTable dtCols = _oleDbConn.GetOleDbSchemaTable(OleDbSchemaGuid.Columns,
new Object[] { null, null, sheetname, null });
foreach (DataRow dr in dtCols.Select(string.Empty, "ORDINAL_POSITION"))
ls.Add(dr["COLUMN_NAME"].ToString());
errorMessage = string.Empty;
return ls.ToArray();
}
catch (Exception ex)
{
errorMessage = ex.Message;
return null;
}
}
