You might be having a problem with two different encoding standards. Windows uses a standard for Arabic called Windows-1256. Farsi might be in the same standard. When it is displayed as UTF8 it displays as you describe, with accented characters. You'll need to either encode as UTF8 from Windows 1256 or just set the encoding to windows 1256.

I try to find a solution from many places, but not yet solved...and hence I have a
different issue for update dbf file [free table -vfp] from C# OleDbDataAdapter.
string MyConStr = "Provider=VFPOLEDB.1; Data Source='C:\\Temp'; Persist Security Info=False";
VFPDAp = new OleDbDataAdapter();
VFPDAp.InsertCommand = new OleDbCommand();
VFPDAp.UpdateCommand = new OleDbCommand();
VFPDAp.InsertCommand.CommandText = "insert into my_table1 (my_time,reminder) values(?, ?, ?)";
VFPDAp.UpdateCommand.CommandText = "update my_table1 set my_time=?, reminder=? where sl_no=? ";
VFPDAp.InsertCommand.Connection = OleCon1;
VFPDAp.UpdateCommand.Connection = OleCon1;
OleDbParameter Par1 = new OleDbParameter("my_time", -1);
Par1.DbType = DbType.String;
Par1.SourceColumn = "my_time";
Par1.ParameterName = "my_time";
OleDbParameter Par2 = new OleDbParameter("reminder", -1);
Par2.DbType = DbType.String;
Par2.SourceColumn = "reminder"; Par2.ParameterName = "reminder";
OleDbParameter Par3 = new OleDbParameter("my_time", -1);
Par3.DbType = DbType.String;
Par3.SourceColumn = "my_time";
Par3.ParameterName = "my_time";
OleDbParameter Par4 = new OleDbParameter("reminder", -1);
Par4.DbType = DbType.String;
Par4.SourceColumn = "reminder";
Par4.ParameterName = "reminder";
VFPDAp.InsertCommand.Parameters.Add(Par1);
VFPDAp.InsertCommand.Parameters.Add(Par2);
VFPDAp.UpdateCommand.Parameters.Add(Par3);
VFPDAp.UpdateCommand.Parameters.Add(Par4);
OleCon1.ConnectionString = MyConStr;
OleCon1.Open();
VFPDAp.Update(VfpTbl);
OleCon1.Close();
Thanks For The Helps

Your update-command has three question marks (parameters), yet you assign only two. s1_no isn't added, and will be required.

Thanks Eddy.![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif)
While posting time unchecked, but my original code is
VFPDAp.InsertCommand.CommandText = "insert into my_table1 (my_time,reminder) values(?, ?)";
VFPDAp.UpdateCommand.CommandText = "update my_table1 set my_time=?, reminder=? where reminder=? ";
But showing the same error,
SQL: Column 'Q0P2' is not found
Thanks Again

Same answer still; you have 3 question-marks in there. That means that a IDbCommand will expect three parameters. It will fail if you only supply 2. From the previous code, it looks as if the primary key is missing.
"Which" record would the statement update? You'll either have to remove the condition (in which case "ALL" records will be updated, which is prolly false) or supply the third parameter.

Firstly your code is not formatted so it is very difficult to read, please surround it with <pre> tags. Secondly, people here are unlikely to spend time analysing this code for you. Try it yourself to see whether it suits your needs and come back here when you have a more specific question.
One of these days I'm going to think of a really clever signature.

This is totally the wrong way to ask a question. See here[^].
First try yourself, if you get stuck or don't understand a specific part of it, come back here.
Nobody will do the work for you, but generally will point you in the right direction if they can.

my solution has two project. one is my actual project and another one is setup project. my actual project has one report folder where i store my all ssrs report.i have one folder in setup project called "SSRS_Repor". now i want that when i will do batch build then setup for my project regenerate and then i want to copy all files from report folder of my actual project to SSRS_Repor in my setup project. if i can do this kind of automation of copying files from one location to another folder of my setup project then i could be get rid of manual copying of rdls files. i hard this is possible by setup/deployment projects. i search google for this for details step-by-step instruction but got no good link. so please guide me how can i do it.
i post it to another forum too and some one told me below this
Open or create a setup/deployment project in Visual Studio 2005
Press F4 to display the Properties window
Click on the name of your setup/deployment project in the Solution Explorer
Click on the PostBuildEvent item in the Properties window to cause a button labeled "..." to appear
Click on the "..." button to display the Post-build Event Command Line dialog
Add a command line of your choice in the Post-build event command line text box
Build your project in Visual Studio and verify that the post-build event is executed after the main MSI build
so it is ok but what i need to write for copying files from one location to another location that is not clear to me. so now this is most important for me what to write for copying file during setup generation.
i got another clue like below one. script for setup Pre/Post Build Event but not aware properly. i got a sample like
copy /Y "$(TargetDir)$(ProjectName).dll" "$(SolutionDir)lib\$(ProjectName).dll"
the above statement or line is not clear to me. what i need to write in my case? so need step-by-step guide.

copy /Y "$(TargetDir)$(ProjectName).dll" "$(SolutionDir)lib\$(ProjectName).dll"
This command copies a dll with the same name as the project, from the directory where it has been created to a directory called lib under the main solution directory. The /Y suppresses prompts to the user to confirm overwriting existing files. You can check the values of the macro parameters by editing the command and clicking on the Macros >> button.
One of these days I'm going to think of a really clever signature.

we know that a solution can have multiple project. so my solution has got two project like one is my main project and another is setup project.my main project has report folder and setup project has report folder too. now i want to write a script like as example copy /Y "$(TargetDir)$(ProjectName).dll" "$(SolutionDir)lib\$(ProjectName).dll"
which will copy all rdlc files from report folder of my main project to report folder of setup project. can you please give me a right script which will copy all rdlc files from report folder of my main project to report folder of setup project.
so just click on this link http://i.stack.imgur.com/hEZBa.png and you see my project structure and also understand from where i want to copy all rdlc files. thanks

As I said before, you can find the relevant directory paths from the macros in your project, so you just need something like :
copy /Y "$(ProjectDir)rdlcdir\*.rdlc" "$(SolutionDir)lib"

Hello. I am confronting basic polymorphic issue in my small project. Classes Layer1 use classes from Layer2. Here is my design for Layer1
public class BaseLayer1
{
public virtual Function()
{}
}
public class ChildLayer1 : BaseLayer1
{
BaseLayer2 base2 = new BaseLayer2();
public override Function()
{
base2.Function();
}
}
Now overriden function in child class gets called here. But virtual function in base class from Layer2 is not getting called here (hence; in child classes of Layer2 as well) . Here is what I am trying
public class BaseLayer2
{
public virtual Function()
{}
}
public class Child1Layer2 : BaseLayer2
{
public override Function()
{}
}
public class Child2Layer2 : Child1Layer2
{
public override Function()
{}
}
What's wrong with my understanding with polymorphism in c# ? Thanks for any pointers.
This world is going to explode due to international politics, SOON.

When you everride a method, that gets called instead of the one in the base class, not as well as.
If you need the base class's method to be called as well, the inheriting class should call base.Function().

DaveyM69 wrote: If you need the base class's method to be called as well, the inheriting class should call base.Function()
Thanks for reply. As mentioned earlier, I have divided my classes in two layers.
If see my first piece of code in Layer1 again, I have commented that: Should go to Base Class in Layer2 as well. Which means I am calling methods of some other class (not the Base Class of Layer1).

Ahh, I think I understand what you mean now.
You expect that the classes derived from BaseLayer2 will have their Function() called when you call base2.Function()?
If so, that will only happen if the BaseLayer2 instance you call the method on (base2) is actually one of the derived classes. So:
BaseLayer2 base2 = new Child1Layer2();
or
BaseLayer2 base2 = new Child2Layer2();

THANK YOU. This is what I exactly meant. Since I am really learning it, can you explain WHY? Because this works absolutely fine in C++.

I'm sure it doesn't! Try it and if it does work, post the C++ code here.

What are you expecting?
using System;
public class BaseLayer1
{
public virtual void Function()
{ Console.WriteLine("BL1"); }
}
public class ChildLayer1 : BaseLayer1
{
BaseLayer2 base2 = new BaseLayer2();
public override void Function()
{
Console.WriteLine("CL1");
base2.Function();
}
}
public class BaseLayer2
{
public virtual void Function()
{Console.WriteLine("BL2");}
}
public class Child1Layer2 : BaseLayer2
{
public override void Function()
{Console.WriteLine("C1L2");}
}
public class Child2Layer2 : Child1Layer2
{
public override void Function()
{Console.WriteLine("C2L2");}
}
class Starter {
public static void Main(){
new ChildLayer1().Function();
}
}
Run this: you get
CL1
BL2
What do you think it should be? That is what you are calling: ChildLayer1 which calls BaseLayer2.
|
|
|
|
|
From what the OP posted I think when calling base2.Function(); he expects the Child1Layer2 and Child2Layer2 Function() to get called as well, which of course they won't as BaseLayer2 isn't necessarily either or any of those.
|
|
|
|
|
Yeah I got that impression too but it isn't really clear to me, so I thought I'd ask for the concrete answer he's expecting and go from there.

I have the following linq to sql statement that I want to use in a C# 2008 application that connects to a sql server 2008 r2 database.
var varGoodTransCount = (from t in rData.Trans
join iw in rData.Ibooks on t.Ibook_ID equals iw.Ibook_ID
join ip in rData.IPacks on iw.PID equals ip.PID
where ip.TNum == SPkgID
group ip by ip.TNum into g
select new { TNum = g.Key, Frequency = g.Count() }).FirstOrDefault();
The line of code that has the problem is
If (varGoodTransCount.Frequency != null)
When I try to reference varGoodTransCount.Frequency, the error message says this is not an instance of an object.
Thus can you tell me what is wrong and how I can fix the problem?

Without your database data it is not possible to be specific, but I would suspect that there are no rows which match your where condition.
As a result, FirstOrDefault will return a null, and you would get the error you describe.
