How to determine if a dll is built for 32-bit, 64bit or Any CPU

CorFlags.exe is part of the .NET Framework SDK. I have the development tools on my machine, and the simplest way for me determine whether a DLL is 32-bit only is to:

• Open the Visual Studio Command Prompt (In Windows: menu Start/Programs/Microsoft Visual Studio/Visual Studio Tools/Visual Studio 2008 Command Prompt)
• CD to the directory containing the DLL in question
• Run corflags like this: corflags MyAssembly.dll

You will get output something like this:

   Microsoft (R) .NET Framework CorFlags Conversion Tool.  Version  3.5.21022.8
Copyright (c) Microsoft Corporation.  All rights reserved.
Version   : v2.0.50727
CLR Header: 2.5
PE        : PE32CorFlags  : 3
ILONLY    : 1
32BIT     : 1
Signed    : 0

The key is the "32BIT" flag as documented above: 1 = x86; 0 = Any CPU.

For x64 only the output would be (plus after 32): PE: PE32+

How to read connection string

 string connectionString = ConfigurationManager.ConnectionStrings[connectionName].ConnectionString;  

Make sure to add reference to System.configuration in your project.

How to open a file locked by other process

Trying to open a file which is being used by another process will result in an exception.

For example, when we try to open a word document opened and locked by other process, we will get an exception.

Here is the sample code that results in exception:

 using (FileStream fs = new FileStream(fileToUpload, FileMode.Open, FileAccess.Read))  
 {  
  fileContents = new Byte[fs.Length];  
  fs.Read(fileContents, 0, Convert.ToInt32(fs.Length));  
 }  

Inorder to resolve this,

we need to use another overload of the FileStream constructor.

Just add FileShare.ReadWrite to the parameters.

 using (FileStream fs = new FileStream(fileToUpload, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))  
 {  
 fileContents = new Byte[fs.Length];  
 fs.Read(fileContents, 0, Convert.ToInt32(fs.Length));  
 }  

This overload of the FileStream constructor allows to open a file in a non-exclusive mode.

Error: A table, Extended Data Type, Base Enum or class called {TableName} already exists. Import of table aborted.

Sometimes during import of an xpo file, we might encounter the following error:

A table, Extended Data Type, Base Enum or class called {TableName} already exists. Import of table aborted.

This errors is a critical error and it stops the import of xpo.

REASON: In majority of cases this error is due to caching.

FIX: In order to resolve this, clear all cache files - .AUC files from the users AppData folder.

• Close AX 2012 client
• Browse to the folder "C:\Users\{userName}\AppData\Local (Windows 2012 Server)
• Delete all AUC files
• Start AX 2012 client and start import.

#Happy coding :)
