The main goal of the Clang project is to create create a new C, C++, etc front-end for the LLVM compiler. Clang is an open source project and you can download it here. You even have a clang-format plugin for Visual Studio on that page, however I do not recommend use the Visual Studio plugin once in my tests, at least at the time I did it, it did not work properly with the most current versions of Visual Studio. If you use the executable, you will be able to integrate it anyways by following the information of this post....

To know the CPU information can be extremely utile when you want to install a third party software that does not distribute it software using Personal Package Archives (“PPAs”) and therefore to be able to install it using the command “apt-get”. On those cases, usually the installation process will require you to copy a file to your linux device that should be selected among different processors and distributions information. The CPU information is located on the “/proc/cpuinfo” file. You can visualize this file content by executing the following command on your Linux Terminal: $ more /proc/cpuinfo Note: This information was...

Introduction Synergy is a VKM (Virtual Keyboard and Mouse) software that allows you to share your keyboard and mouse with computers running different operational systems (E.g.: Linux, Windows, etc..). There are alternative softwares that can replace Synergy if you would like to share your keyboard and mouse with devices that use the same operational system (E.g.: Mouse Without Frontier for Microsoft Windows). However, the attractiveness of Synergy is the fact it is an open source software and can run in multiple operational system platforms. The following walkthrough will demonstrate on how to install the Synergy software and share your Windows...

The VxWorks version 7.0 is not compiling when a program uses files system functions as mkdir, rmdir, etc. This is caused by bug on this version of VxWorks and affects all the file system functions that uses the usrFsLib library. This is a bug reported on the following link: https://knowledge.windriver.com/en-us/000Products/000/020/000/080/000/000_V7STO-226%3A_mkdir()_no_more_available_in_RTP_libc To solve the problem you do not need to change the makefile as suggested by the proposed solution link. Just add the library on your project (Build Properties » Libraries » Add fsapiUsr library):

To find string into several files, you can use the Windows Powershell and the Get-ChildItem (Dir) command-let as following: dir <<v>base_directory> -I <<v>file_extensions[]> -R | Select-String <<v>strings_to_search[]> E.g.: dir dir c:\fso -I *.txt, *.log -R | Select-String fail, success, pending This command looks for the string “success” and “pending” into all sub directory of the folder “c:\fso”

Introduction Several times you are required to call an C++ code from a C code. One example where you want to have such interoperability is when you use an operational system, as for example VxWorks realtime program, where the program executions requires an entry-point in C code. On this article it is proposed a 3 step procedure that will allow you to execute such interoperability. Step 1 - Create an Interoperability Header (CodeInteroperability.h) This header will contain your entry point class and 3 additional global functions to Create, Run and Destroy your entry point class. Step 2 - Codify your...

Google Test Framework (GTest) requires your project to be an executable. When using Visual Studio, it is common for you to create a flavor of project from the Visual Studio Test framework. In this way you might have your units tests available on both frameworks. To do it you create the new flavor and them change the project properties to be an executable and properly link with the GTest libraries. Them when you compile your new project flavor you receive the following link error: Error: _winmain@16 executable link error This error happens when you are linking an executable without an...

You cannot access directly STL vector index on Visual Studio, however, there is a way to access vector value in debug mode though a RawView: ((< vector_name >)._Myfirst)[< vector_index >] E.g.: ((my_vector)._Myfirst)[10] - Access the index 10 of the vector my_vector

When investigating memory leaks problems that involves OLE Strings (E.x.: BSTR, CComVariant, etc…), be aware that by default Windows caches strings created by SysAllocString and freed by SysFreeString functions to increase the overall COM/DCOM performance. This makes false leaks on memory leaks tools (E.g.: DebugDiag). To disable the cache of the OLE strings, you can introduce following Environment variable. OANOCACHE=1 If you are running the tests over a Windows service (E.g.: IIS), be sure you restart the computer for the changes to take effect.

Indusoft - Linked Picture Default Directory On the Indusoft Web Studio v7.1 + Service Pack 2 we changed the default path of linked pictures to be relative to the Web folder. On older versions, this path were relative to the application folder. In case you created an application on older versions, your relative linked pictures might not load properly. To correct this problem you can enter the following entry on you application file (.App): [Options] UseAppPathForLinkedPictures=1

There are some programs that are life change and in my opinion the PhraseExpress is one of them. Phrase Express WebSite The Phrase Express program monitors everything you type on the keyboard and allows you to configure several actions based on the key pressed. It do not only evaluate a sequence of keys pressed at the same time, but evaluates the previous texts typed in order to provide actions that are very flexible and configurable. For example it would not be very useful to have a kind of Visual Studio intellisense in any program that you use? More than a...

This article informs steps that can be used during the creation of your device SDK using the Platform Builder, as well steps to be used during the compilation of your program that will speed up the overall performance of your application on ARMv7 processors. Introduction Newer processor types usually introduces techniques to improve the performance, reduce the power consumption, etc. however, those functionalities might need the introduction of specifics processor commands not available on older processors architectures that is neither always used by the compilers nor properly enabled on the SDKs. This is the case when using Microsoft Visual Studio...

Windows 7 have introduced a new feature, called TCP/IP Auto Tunning, that dynamically changes the TCP/IP package sizing. This improves the speed of the TCP/IP communication. However, old Windows Servers operational systems, E.g.: Windows 2000, have problems handling the TCP/IP Auto Tunning capability. This makes the network communication between Windows 7 and those old Windows Servers really slow. Unfortunately the operational systems where this problem might happen, are no longer supported by Microsoft and therefore no solution is available on the Server side. But, you can disable the TCP/IP Auto Tunning capability on the client side by using the command...

It is amazing the amount of information that we have in our hands though the Internet.

The image below shows the difference between a Frame and View windows when using a MFC Frame/View architecture. On the MFC Frame/View architecture, each document can be linked with one or more View. The View is nothing more that a representation of the document. You can have the same document presented in several different formats by using one View for each format presentation. A View will always be inside a Frame and a Frame can have more the one View.

This small article explains the definition of ETD and ECD. ETD stands for equipment terminal data, examples of ETDs are PCs, PDAs, Tables, Smart phones, HMI, etc. On those devices, that usually send the information, the TX represents an output and the RX represents an input. ECD stands for equipment communication data, examples of ECDs are Modem, Conversors (RS232/RS485), etc. On those devices, that usually receives or follows the information, the TX represents an input and the RX represents and output. Summary ETD --> TX (Out) RX (IN) ECD --> TX (In) RX (Out)

The CEServer is able to relaunch an application in case it detects that for some reason the application is not running. This behavior might be utile if you have on critical operations that your application cannot in anyway be stopped. To enable this functionality edit the CEServer.ini with the following entry: [Watchdog] Enable = 1 TimeOut = 600 This will enable Watchdog functionality restarting the CEView and Viewer in case the CEServer identifies that any of the programs are out for more than 600 milliseconds.
