computerpublic wrote: string temPath = Path.GetTempFileName();
From the MSDN documentation:
Creates a uniquely named, zero-byte temporary file on disk and returns the full path of that file.
You have created an empty file; when you try to read it, you won't get any bytes returned, because it's empty.
computerpublic wrote: Console.WriteLine("{0}={1}",arry[count],buffer[count]);
As you've written it, the code would print out "NUMBER=NUMBER" for each byte in the input file. Since there are no bytes in the input file, it won't have anything to display.
computerpublic wrote: string filePath2 = Path.Combine("C:\\check", Path.GetFileName(filePath));
output.Write(buffer, 0, bytesRead);
Apart from the fact that the input file is empty, your code suggests that you're trying to write to a file in the directory C:\check, but you're actually writing to another temporary file, which will be in the %TEMP% folder.
computerpublic wrote: turn each byte into a number and SHOW IT, turn the number back to a byte and SHOW IT
A byte is a number. It's a number between 0 and 255. There's no need to turn it into a number.
Saying "I need to turn this byte into a number" is like saying "I need to turn this fluid into a liquid". There's no conversion needed.
What I suspect you want to do is display the byte in different number bases - for example, in binary (base 2) and decimal (base 10). That's just about formatting the number, not converting it to a different type.
Based on your description, the following code should do what you're after:
using System;
using System.IO;
namespace Applica
{
static class Program
{
DirectoryInfo da = new DirectoryInfo("C:\\Folder1");
if (!da.Exists)
{
Console.WriteLine("The folder '{0}' does not exist.", da.FullName);
return;
}
FileInfo[] Arr = da.GetFiles();
if (Arr.Length == 0)
{
Console.WriteLine("There are no files in the folder '{0}'.", da.FullName);
return;
}
FileInfo ap = Arr[Arr.Length - 1];
long Totbyte = ap.Length;
string filePath = ap.FullName;
Console.WriteLine("Total Bytes = {0} bytes", Totbyte);
const int BufferSize = 1024;
byte[] buffer = new byte[BufferSize];
string destinationPath = Path.Combine("C:\\check", Path.GetFileName(filePath));
using (Stream input = File.OpenRead(filePath))
using (Stream output = File.OpenWrite(destinationPath))
{
int bytesRead;
while ((bytesRead = input.Read(buffer, 0, BufferSize)) > 0)
{
for (int count = 0; count < bytesRead; count++)
{
byte theByte = buffer[count];
string theByteInBinary = Convert.ToString(theByte, 2).PadLeft(8, '0');
Console.WriteLine("{0} = {1}", theByteInBinary, theByte);
}
output.Write(buffer, 0, bytesRead);
}
}
}
}

The bytesRead may differ from the BufferSize. So, you should do the for from 0 to less than bytesRead (you are doing the for to less than buffer.Length).
You should use an ASCII text file for this to work, as other formats may use more than one byte per character.
You don't need that Totbyte variable... you should always use the bytesRead instead.

Pop up error message when I call AS400 Stored Procedures via c# application.But when I put select query to As400 via c# application it is working.
error MSG -"ERROR [HY000] [IBM][Client Access Express ODBC Driver (32-bit)][DB2/400 SQL]SQL0440 - Routine GVSP07 in AMAIN1 not found with specified parameters."
All SP parameters and SP name ok.
Please any one can help me?????
|
|
|
|
|
Well, considering you haven't shown us any code at all, all we can say is that that particular routine isn't found in that database with those specific parameters. Perhaps if you provided a bit more information, such as the code. On the plus side, you have given us details of what the exception was, which is a lot more than we usually get.
|
|
|
|
|
I mention below code that I use to call AS400 SP
(SP Name-GVSP07
OdbcConnection conOdbc = new OdbcConnection("DSN=GIFT1;UID=GIFT1;PWD=GIFT1;");
public void OpenODBCConnection()
{
try
{
if (conOdbc.State == ConnectionState.Closed)
{
conOdbc.Open();
}
}
catch (Exception ex)
{
throw ex;
}
}
OdbcCommand ODBC = new OdbcCommand("call AMAIN1.GVSP07",conOdbc);
ODBC.Parameters.Add("GR1X", OdbcType.Double, 7);
ODBC.Parameters["GR1X"].Direction = ParameterDirection.Input;
ODBC.Parameters["GR1X"].Value = 3020;
ODBC.Parameters.Add("GUSX", OdbcType.Char, 10);
ODBC.Parameters["GUSX"].Direction = ParameterDirection.Input;
ODBC.Parameters["GUSX"].Value = "g";
ODBC.CommandType = CommandType.StoredProcedure;
ODBC.ExecuteNonQuery();
|
|
|
|
|
It seems that SP AMAIN1.GVSP07 does not have GR1X (double) and GUSX (char[10]) parameters...
Can you see the SP code?
I'm not questioning your powers of observation; I'm merely remarking upon the paradox of asking a masked man who he is. (V)

What does your Stored Procedure look like?
|
|
|
|
|
catch (Exception ex)
{
throw ex;
}Oh no! What's the use of that catch-throw pattern that will only destroy the proper CallStack?
Some better solutions:
- Do not catch at all here - that throw ex must be handled somewhere else anyway, so don't bother.
- Log it and re-throw:
catch (Exception ex)
{
LogException(ex);
throw;
}
- wrap it in a "meaningful" exception of your own, and throw that
catch (Exception ex)
{
throw new YourConnectingToDatabaseFailedException("Could not open the connection to database ...", ex);
}

This is a sample code for testing C# application link to AS400 ,that why i used this simple code.anyway thanks for your comment....

Hi, I have one table on database and 2 data table on Program. I want join Tables with Data table
Database Table Name WarehouseStore
Field = WarehouseStoreiD,WarehouseiD, ProductiD, ProductName,ProductValue
Datatable 1 Name: dtProduct
Field = identity,iD
Datatable 2 Name: dtWarehouse
Field = identity,iD
How Can I Join them like this code on Join Sql Tables?
SELECT WarehouseStore.ProductID, WarehouseStore.ProductCode, WarehouseStore.ProductName, ,WarehouseStore.ProductValue FROM WarehouseStore INNER JOIN dtProduct ON dtProduct.iD =WarehouseStore.ProductCode INNER JOIN dtWarehouse ON dtWarehouse.iD =WarehouseStore.WarehouseiD
-- modified 7-Jul-14 5:18am.

Execute the query with the JOIN on the database BEFORE you load it into a datatable.
Why do you insist on doing it after loading it in a datatable?

i can Load data warehouseStore on DataTable and insert user Data on 2 other DataTable bout I cant Join table with DataTable For show Report.
data table dtProduct Include data user select product and dtWarehouse Include data user select Warehouse and WarehouseStore Table Include All Warehouse Data.
when user insert into dtProduct ProductiD and Insert into dtWarehouse WarehouseiD must select just data on WarehouseStore When Equals to User Insert Data.

Why not? What error is it showing?
Can you execute the query from Sql Managment Studio to verify that it is correct?
..and yes, the result of the query would be loaded into a single datatable; that's what a join would do. Can you show the code where you execute the sql and read it into memory?

The SQL=query does not accept variables from C# code. You'll have to find another way to do it. Thinking about it, it'll probably be simply called "Product" in the database-server, not "dtProduct". Try changing that

Dear Group Members,
I am using Lucene.net for building a search engine. In course of development I came across providing filters to the search.
As I went through the Lucene documentation I came across ChainedFilter. It is a way to combine multiple filters together. However this class is not available in any of the assemblies (ver 3.0.3). The same is confirmed by multiple blog-posts. But I didn't come across any post where it is mentioned, what can be the performant way to club multiple filters together and provide it to Search().
Can someone please provide some input related to this.
Regards,
Shubhanshu

Simple:

Hide();
mf.ShowDialog();
Show();

You mean "minimized"? I wouldn't recommend that, as a minimized form should not be displaying stuff.
You might want to set the parent of the sub-form though;
fo.ShowDialog(this);
