+
+## هدف پروژه
+این پروژه یک برنامه **Windows Forms** با **.NET Framework 4.5** و ساختار کلاسیک (non-SDK) است.  
+فایل پروژه: `MyShop.csproj`  
+فرم اصلی فعلی: `Form1`  
+پایگاه داده هدف: **Microsoft Access**
+
+---
+
+## قوانین کلی برای Agent (Codex)
+
+1. **سازگاری نسخه‌ای (خیلی مهم)**
+   - تمام کدها باید با `.NET Framework 4.5` سازگار باشند.
+   - از سینتکس‌ها و قابلیت‌های جدید C# که ممکن است در ابزارهای قدیمی مشکل ایجاد کنند استفاده نشود.
+   - فرض بر سازگاری با محیط قدیمی Visual Studio / MSBuild باشد.
+
+2. **زبان کامنت‌ها**
+   - تمام کامنت‌های کد باید **فارسی** باشند.
+   - متن‌های توضیحی داخل کد (در صورت نیاز) فارسی نوشته شوند.
+
+3. **ساخت و اجرا**
+   - ساخت و اجرا از طریق **Visual Studio** انجام می‌شود.
+   - تغییراتی که نیازمند ابزار خارج از روال عادی Visual Studio هستند اعمال نشود مگر با درخواست صریح.
+
+4. **قانون تغییرات**
+   - تغییرات باید **حداقلی، دقیق و قابل‌ردیابی** باشند.
+   - از بازنویسی گسترده‌ی فایل‌ها بدون نیاز خودداری شود.
+   - قبل از اعمال تغییرات پرریسک، توضیح کوتاه از اثر تغییر ارائه شود.
+
+---
+
+## قوانین مربوط به WinForms و Designer
+
+1. فایل‌های زیر جزو ساختار اصلی WinForms هستند:
+   - `Form1.cs`
+   - `Form1.Designer.cs`
+   - `Program.cs`
+   - `Properties/*`
+
+2. **ویرایش `*.Designer.cs` مجاز است**، اما با دقت:
+   - فقط تغییرات لازم برای پیاده‌سازی UI خواسته‌شده انجام شود.
+   - نام کنترل‌ها معنی‌دار و پایدار انتخاب شوند.
+   - از حذف/تغییر ناخواسته تنظیمات فرم و کنترل‌ها جلوگیری شود.
+
+3. اگر UI بر اساس تصویر/طرح خواسته شد:
+   - ابتدا لیست کنترل‌های لازم، نام‌ها و نوع‌ها مشخص شود.
+   - سپس `InitializeComponent` به‌صورت منظم و قابل‌فهم تولید/ویرایش شود.
+   - در صورت ابهام در فاصله‌ها/ابعاد، از مقادیر منطقی و قابل اصلاح استفاده شود.
+
+---
+
+## قوانین پایگاه داده (Microsoft Access)
+
+1. اتصال دیتابیس با `OleDb` انجام شود (سازگار با .NET Framework 4.5).
+2. از **Query پارامتری** استفاده شود (جلوگیری از خطا و Injection).
+3. Connection string در `App.config` نگهداری شود (نه هاردکد داخل فرم).
+4. عملیات دیتابیس:
+   - `using` برای `OleDbConnection`, `OleDbCommand`, `OleDbDataAdapter` رعایت شود.
+   - مدیریت خطا با `try/catch` انجام شود و پیام مناسب به کاربر نمایش داده شود.
+5. نام جدول/فیلدها در صورت استفاده از کلمات رزرو‌شده Access، با براکت `[]` مدیریت شوند.
+
+---
+
+## سبک کدنویسی
+
+1. نام‌گذاری:
+   - کلاس‌ها و متدها: واضح و معنی‌دار.
+   - کنترل‌ها: پیشوند مناسب (مثل `txtName`, `btnSave`, `dgvProducts`).
+2. متدها کوتاه و مسئولیت‌محور باشند.
+3. منطق دیتابیس تا حد ممکن از کد مستقیم UI جدا شود (در حد سبک پروژه).
+4. از افزودن وابستگی/NuGet جدید بدون درخواست صریح خودداری شود.
+5. از تغییر خودکار فایل‌های `Properties/*.Designer.cs` مگر در صورت نیاز مشخص خودداری شود.
+
+---
+
+## موارد خارج از محدوده (مگر با درخواست کاربر)
+
+- افزودن فریم‌ورک‌های جدید (WPF, ASP.NET, EF جدید و ...)
+- مهاجرت پروژه به نسخه‌های جدید .NET
+- افزودن زیرساخت تست خودکار
+- تغییرات معماری سنگین
+
+---
+
+## چک‌لیست قبل از تحویل تغییر
+
+- [ ] کد با .NET Framework 4.5 سازگار است.
+- [ ] کامنت‌ها فارسی هستند.
+- [ ] تغییرات حداقلی و مرتبط با درخواست هستند.
+- [ ] در صورت استفاده از Access، کوئری‌ها پارامتری هستند.
+- [ ] فایل‌های Designer بدون آسیب به ساختار فرم ویرایش شده‌اند.
+- [ ] برنامه در Visual Studio قابل Build/Run است.
+
+---
+
+## قالب پاسخ‌دهی Agent برای هر تسک
+
+1. خلاصه کوتاه از کار انجام‌شده
+2. لیست فایل‌های تغییرکرده
+3. نکات مهم/ریسک‌ها
+4. اگر ابهام وجود داشت: سوال شفاف قبل از اعمال تغییر نهایی

+                
+    There are any number of "resheader" rows that contain simple 
+    name/value pairs.
+    
+    Each data row contains a name, and value. The row also contains a

+    text/value conversion through the TypeConverter architecture. 
+    Classes that don't support this are serialized and stored with the 
+    mimetype set.
+    
+    The mimetype is used for serialized objects, and tells the 
+    ResXResourceReader how to depersist the object. This is currently not 
+    extensible. For a given mimetype the value must be set accordingly:
+    
+    Note - application/x-microsoft.net.object.binary.base64 is the format 
+    that the ResXResourceWriter will generate, however the reader can 
+    read any of the formats listed below.

+    value   : The object must be serialized with

+  <!-- 
+    Microsoft ResX Schema 
+    
+    Version 2.0
+    
+    The primary goals of this format is to allow a simple XML format 
+    that is mostly human readable. The generation and parsing of the 
+    various data types are done through the TypeConverter classes 
+    associated with the data types.
+    
+    Example:
+    
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+                
+    There are any number of "resheader" rows that contain simple 
+    name/value pairs.
+    
+    Each data row contains a name, and value. The row also contains a 
+    type or mimetype. Type corresponds to a .NET class that support 
+    text/value conversion through the TypeConverter architecture. 
+    Classes that don't support this are serialized and stored with the 
+    mimetype set.
+    
+    The mimetype is used for serialized objects, and tells the 
+    ResXResourceReader how to depersist the object. This is currently not 
+    extensible. For a given mimetype the value must be set accordingly:
+    
+    Note - application/x-microsoft.net.object.binary.base64 is the format 
+    that the ResXResourceWriter will generate, however the reader can 
+    read any of the formats listed below.
+    
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+    
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array 
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.
