Cuộc sống tươi đẹp

Khi một ngày trôi qua không màu sắc, sự buồn chán làm cuộc sống trở nên vô vị. Bạn rơi vào trạng thái ủ rũ, không còn hứng thú đối với tất cả mọi việc.

Làm thế nào để cuộc sống trở nên tươi đẹp?

Maximum Cursors Exceeded

Lập trình ArcGIS thường gặp lỗi ‘ORA-01000: maximum open cursors exceeded ’. Tại sao lại xảy ra lỗi này? Cách giải quyết thế nào? Nói chung, lỗi này xảy ra trong khi duyệt qua các đối tượng trong một featureclass. Bất cứ khi nào chúng ta duyệt qua một featureclass hoặc một table, chúng ta cần giải phóng đối tượng cursor sau khi sử dụng nó.

Một ví dụ đơn giản trong .NET để giải phóng đối tượng cursor.

//VB.NET

Public Sub MarshalObject(ByRef obj As Object)
If Not obj Is Nothing Then
If System.Runtime.InteropServices.Marshal.IsComObject(obj) Then
System.Runtime.InteropServices.Marshal.ReleaseComObject(obj)
End If
obj = Nothing
End If
End Sub

C#.NET sample

private static void MarshalCOMObject(object obj)
{
if (obj != null)
{
if (System.Runtime.InteropServices.Marshal.IsComObject(obj))
{
System.Runtime.InteropServices.Marshal.ReleaseComObject(obj);
obj = null;
}
}
}

Bạn có thể gọi hàm này ở những nơi thích hợp. Điểm quan trọng là bạn cần giải phóng cả đối tượng ‘ROW’ và đối tượng ‘CURSOR’ sau khi sử dụng. Giả mã sau đây mô tả giải pháp trong C#.NET

try
{
//Assuming variables are declared pQueryFilter = new QueryFilterClass();
pQueryFilter.WhereClause = “”;
pCursor = pFeatureClass.Search(pQueryFilter, false);
pFeature = pCursor.NextFeature();
while (pFeat != null)
{
//Do whaterver required
//Release feature row object using MarshalCOMObject subroutine.
MarshalCOMObject(pFeature);
pFeature = pCursor.NextFeature();
}
//After looping is finised release cursor object using MarshalCOMObject subroutine.
MarshalCOMObject(pCursor);
}
catch (Exception ex)
{ }
finally
{
//In case any error occured within try block, finally block releases cursor and
//row object using MarshalCOMObject subroutine.
MarshalCOMObject(pFeature);
MarshalCOMObject(pCursor);
}

So sánh ArcGIS Explorer (AE) và Googe Earth (GE)

Hiện nay, nhu cầu về GIS 3D đang ngày càng phát triển mạnh, nổi bật trong số đó phải kể đến hai đại gia là ESRI và Google. ESRI cho rằng ArcGIS Explorer chủ yếu tập trung vào việc khai thác dữ liệu và có nhiệm vụ khác với Google Earth. Thực tế thì nhiệm vụ của hai phần mềm này khá giống nhau, chỉ có cách tiếp cận là khác nhau. Bài viết này không đi sâu vào phân tích các chi tiết khác mà chỉ tập trung chủ yếu vào so sánh nội dung của hai sản phẩm trên tập trung trên 4 khía cạnh sau:

1. Định dạng dữ liệu

Về mặt này thì rõ ràng là AE vượt lên trên GE. AE cho phép bạn sử dụng các file có định dạng của AE (.nmf), server (WMS, IMS, file server), geodatabases, shapefile, raster, và KML. Một danh sách khá ấn tượng, định dạng raster hỗ trợ tới hơn 30 loại khác nhau, dù cho chúng yêu cầu phải có hệ tọa độ đi kèm.

Về phía GE, bạn có thể sử dụng 2 định dạng là KML và KMZ. Với phiên bản miễn phí, có thêm sự hỗ trợ định dạng 3D sketchup (.skp) và COLLADA (.dae). Với phiên bản Pro và Enterprise, hỗ trợ thêm shapefile và .tab của MapInfo và định dạng ảnh TIFF bao gồm GeoTiff, National Imagery Transmission Format (.ntf), Erdas Imagine Images (.img), Atlantis MFF Raster (.hdr), PCIDSK Database File (.pix), Portable Pixmap Format (.pnm), Device Independent Bitmap (.bmp).

Như vậy mặc dù GE hỗ trợ khá nhiều định dạng ảnh nhưng bạn lại phải trả tiền để có được các tính năng đó, trong khi AE lại hoàn toàn miễn phí. Như thế có thể nói ESRI đã thắng trong phần này.

2. Nguồn dữ liệu

Ngoài việc hỗ trợ nhiều định dạng khác nhau, cả hai còn có khả năng lấy dữ liệu từ nhiều nguồn khác. Với AE, bạn có thể truy cập ArcGIS Online trực tiếp thông qua tùy chọn file server, tùy chọn này cho phép bạn truy cập tới một thư mục các file khác. Tùy chọn thứ hai là bạn có thể truy cập vào trang web “Resource Center” thông qua mục help, ở đó bạn có thể download từ các file.nmf. “Resource Center” thân thiện hơn vì nội dung được sắp xếp theo các chủ đề như , “imagery, street, physical features”.

3. Tìm kiếm

4. Đóng gói dữ liệu

Ăn sáng ở Hà nội

Thật không thể tin nổi ăn sáng ở Hà nội lại đắt đỏ đến thế!

Sáng nay, sau một hồi lòng vòng thì mình với Mr. Thường quyết định đi ăn cháo Lươn ở dốc Bưởi. Dạo này khủng hoảng qua đã lâu rùi mà họ làm ăn chán quá, chẳng giống bát cháo lươn tẹo nào, thế mà cũng hết 30K. Ăn uống xong thì đến giai đoạn khó khăn hơn là quyết định đi đường nào đến cơ quan. Vì đang ở Hoàng Quốc Việt nên mình nghĩ đi đường viện E sẽ nhanh hơn (oh, bình thường là như thế). Nhưng hôm nay là ngoại lệ.

Đường đông kinh khủng, đi đến ngã tư Cổ Nhuế thì bị tắc, không thể tiến thêm được cm nào nữa. Một quyết định khôn ngoan cần phải được thực hiện kịp thời. Thế là quay đầu xe, đi theo đường khác. Chưa kịp cười thì một anh công an tiến lại giơ gậy chỉ ngay vào người. Bít là điều gì sẽ xảy ra nhưng đã muộn.

Vậy là thêm 150K xiền phạt vì không chú ý đến đèn giao thông. Oh my gosh, đang đứng giữa ngã tư thì làm sao bít có cái đèn khỉ gió nào đang treo trên đầu cơ chứ.

Đành tự tạo niềm vui cho riêng mình vậy. Hy sinh thêm 15K mua 20 bông hồng đi tặng mọi người. Hy vọng là sẽ có một ngày tốt đẹp )

Ngày đầu tuần nóng bỏng

Hôm nay là ngày trái đất gần với mặt trời, nên thời tiết thật là nắng nóng. Cứ đi ra ngoài là rát mặt bỏng da.

Trời đất đã thế, cuộc sống còn nóng bỏng hơn gấp nhiều lần., Chuyện cơm áo gạo tiền cứ bám theo làm cho con người lúc nào cũng sống vội vã. Cứ đi mà không có thời gian ngoảnh lại xem những dấu chân mình đã để lại như thế nào.

Phải cố lên thôi

Happy minute

Cứ tưởng là thứ 7 và chủ nhật phải ở nhà lụi cụi encrypt solution trong .NET, ) nhưng thật may là trong khi lướt web lại nảy ra ý tưởng thiên tài đi tìm chương trình anti-decompiler.

Thực ra thì ý tưởng này đã có từ lâu nhưng các chương trình trên thị trường hiện nay có giá bán khá cao, vượt quá khả năng đáp ứng về mặt tài chính nên đến giừo vẫn phải làm bằng tay, hiệuq ủa không cao mà tính an toàn lại thấp.

Kết quả là sau một ngày mò mẫm trên mạng, cũng tìm ra được giải pháp. Oh la la, thật là những giờ phút tươi đẹp. Tạm biệt những ngày cặm cụi ngồi đổi từng dòng lệnh, từng namespace, từng class…

Sunday, 13 January 2008 14:33

Hi everyone, today I decided to write a review about the obfuscator and protector for .net application. I don’t intend to write all about the functions of each one. I just write down my notices and some attentions when I make research of these ProObtors (abbreviation for Protector and Obfusctor).

In this version 1.0.0.0 of this article I just write down all of ProObtors for .net.I will insert day by day the review for each of them.

If you post this article to somewhere. Please post souce of it as my site: http://rongchaua.net

I will evaluate each software with the scale 4 for each features : Protector – Obfuscator – License Manager. Some softwares support only 1 or 2 features of above list. Therefore they have low note but it doesn’t mean that they are bad. It’s just because they support little features. Please read the review carefully to have a right vision.

NOTE: This article I wrote one year before. It is now not right anymore. Just take it as a reference. I will fix it as soon as possible. The ProObtors for .Net has changed itself dramatically since last year. They are now more and more better than before.

Review:

This software is a medium choice for small to medium softwares. It provides all of features which a .net software needs: Protect from decompiling, obfuscate assembly and provides a good license manager. But what a pity because these features was not well implemeted.

First about the anti-decompiling (NecroBit) features. As I can see, these featurs become worse day by day. In the ancient version, the author has used the Read/Writeprocessmemory to recover the header of each function in assembly. And write null to 2 values of MetaHeader so that we can not dump the assembly. We (REATeam) have written a script for Olly to unpack and we can restore the assembly completely. I write personally a tool (here ) for this version. But I have never published because after that the author has used another way to protect the assemlies. Now it seems that he is going to build .Net Reactor as wrapper. The assembly will be unpacked on memory and will be there executed. This is a dangerous way because it’s easy for a reverser to unpack and restore code. I note for its protector-feature 2/4.

Second, let’s take a look at his obfuscator features. What does he do? He renames only the namespace, class, functions … and nothing else. There is no string-encryption, no flow-control-obfuscation. It’s bad. Nothing else to say. I note 1/4 for it obfuscator-feature.

Last, the license manager gives many options. We can lock our softwares even Hardware ID. But we must create a seperate file to get the hardware ID. It’s disadvantage. Why doesn’t the author let the Hardware ID be shown in Nag. Therefore I would like to note 3/4 for this features.

Evaluation: 6/12

Assembly Lockbox

Categories: Code protection – Obfuscation.
Homepage: Gibwo
Latest version: Unknown
Description: AssemblyLockbox includes components that are used by your software development team and shipped with your software. The files shipped with your software must simply be present in the same path as your application to work. They do not require their own installation process. An application called AssemblyLockboxBuilder comes with AssemblyLockbox. This application is used by software developers to integrate AssemblyLockbox with your software and automate the process of preparing the protected files for shipment or distribution to a web server.
Features include:

* Re-encryption of your DLLs on the client computer using local information such as network MAC address or hard drive volume id.
* Decryption only in the presence of a USB hardware device.
* Decryption only in the presence of a local license file or some other kind of text file containing a specific series of characters.
* Decryption only if the calling application itself possesses certain attributes.
* Decryption only if the calling application does not have reflection rights.
* Decryption only upon verification by Microsoft Digital Rights Management API.

Review:

It’s pretty difficult to use. I must protect the assemblies during the process of programming. That means everytime when I change the source code of programm I must build the lock dll again. GUI is “ugly” and contains bugs. At last, I can not protect even only one. Therefore I note it for 0/12.

Review:

CliSecure is a product of SecureTeam. They are proud of their methods: Only one function will be unpacked on memory at anytime. It sounds a good one. Because we can not dump whole of assembly to file anymore. But after I reseaching this tool. I have found that they only change the RVA of method. It’s also not more so easy to crack. But I have code the tool to fix the RVA of packed file (here ). Hence I would like to not for protector features 3/4.

The obfuscation features is bad. Only namespaces, classes was obfuscated. I note for 1/4.

License Manager is ok. But it doesn’t support HardwareID lock. I note it for 2/4.

Evaluation : 6/12

* Obfuscation.
* Anti-Debugging, Anti-Tracing.
* Modification Resistance.

Review:

When I read the slogan of CodeVeil : “Don’t just confuse hackers, stop them”, I was very impressed. I think this must be a strong protector which I want. But after I take a look inside. I’m very disappointed. CodeVeil is also a wrapper for .net assembly. It will load .net assembly into memory and .net assembly will be there executed. I just dump file from memory and the dumped file can be viewed with Reflector. It’s bad. Therefore I note for the protection property 2/4.

CodeVeil does also the obfuscation. But it’s just a simple obfuscation. The user string of assembly after dump was all decrypted. Therefore 2/4 should be the note for obfuscation feature.

It doesn’t support License Manager.

Evaluation : 4/12

Dynu .net protector

Categories: Code protection – Obfuscation – License Manager.
Homepage: Dynu
Latest version: Unknown
Description: Dynu .NET obfuscator now offers the sophisticated technologies to protect your .NET sources. The .NET architecture is unprecedented in its degree of power and flexibility. Unfortunately, that design inherently produces a problem for those trying to hide their program’s intellectual property. One of the consequences of the architecture of .NET is that a great deal of information about an assembly is kept with the assembly in a part of the file called the Manifest. This information makes it remarkably easy to not just recompile the assembly, but to decompile it, make modifications, then recompile it. Reverse engineering has always been possible in .NET. Obfuscation can help you avoid this problem by removing unnecessary information from the metadata and scrambling some of the remaining information to make disassembled components fail to recompile. Obfuscation is a technique that provides for seamless renaming of symbols in assemblies as well as other tricks to foil decompilers.
Features include:

* Protection.
* Optimization.
* Symbol renaming.
* Metadata scrambling.
* Flexibility.
* Ease of use.

Hi knut,
Smart Assembly is a good obfuscator too. It has a feature for anti-decompiling. But in my opinion Xenocode is the best one. However Xenocode is too expensive in comparing with SA. You can use SA as your obfuscator if your budget does not allow you to buy an expensive one.

LOCK VIOLATION WHEN SAVE DOCUMENT IN ARCENGINE 0×80030021 (STG_E_LOCKVIOLATION)

ERROR:

Lỗi LOCK VIOLATION xảy ra khi save một document bằng ArcEngine. Lỗi này xảy ra vì khi dùng ReplaceContents, ta thêm trực tiếp Map của document đó vào AxMapControl, như thế thì Map này sẽ đang được sử dụng bởi AxMapControl do đó không thể thay đổi được document.

SOLUTION:

Tạo bản sao của Map của document.

Error: the handle is invalid

Error : A message says “The handle is invalid” pop up when run application in debug mode

Solution: Enable the Terminal Services in Control Panel/Administrative Tools/Services
