This table is geared towards iOS developers who want to start working on android. You can refer this table whenever you are confused about what component to use in android, and also what tool to accomplish a task. I have tried to make it 1:1. So its easy to google the information needed. iOS Android
If you observe the output below, you will see that the progressive, repeated fields , single frame and multiple frame have values in them. This should give you an idea that it’s an interlaced video. Also most interlaced videos will have an ‘i’ in them. e.g. 1080i
I often use console logging to debug when coding in PHP. I use the below command to do this : tail -f /var/log/tpsite/php.log The logs would keep showing up in the terminal, I would need to keep clearing the screen to view my logs more clearly. There is a better way to do this if
Recently I had to design a form which works on both the desktop, tablet and mobile screens. As you know there are a number of resolutions out there, it becomes quite overwhelming to decide which screen resolution to support and not to. This is where the responsive queries come into picture. At the end of

If you XOR a number even times by itself, you will end up with zero but if you do it odd times, you will be getting the number itself. This logic can be used in many different problems, e.g. finding the odd and even number of times a number occurs and so on.
Unix files consist of two parts: the data part and the filename part. The data part is associated with something called an ‘inode’. The inode carries the map of where the data is, the file permissions, etc. for the data. The filename part carries a name and an associated inode number. The directory, as a

Be careful when using _SECURE_SCL option when integrating your DLLs with DLLs you received from someone else. If you have compiled your dlls with this option but the dlls you use havent, you are most likely going to get a runtime application compatibility error. To fix this just remove this option. When secure SCL is
I got this from joel on software. I pasted it here for my reference: Wednesday, October 08, 2003 Ever wonder about that mysterious Content-Type tag? You know, the one you’re supposed to put in HTML and you never quite know what it should be? Did you ever get an email from your friends in Bulgaria
Below is the code to return the parent id of a process, given a process id.

Sometimes data is also stored as message instead of resources. the easiest way to read this is as below: ofstream myfile; myfile.open (“example.txt”); HMODULE handle = LoadLibrary(“AgentRes.dll”); // dll for reading the file DWORD err=::GetLastError(); for(int i=0;i<10000;i++) { LPTSTR lpMsgBuffer=NULL; DWORD dwRet=FormatMessage( FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_HMODULE, handle, i, // number of the corresponding message // you
Sometimes or most times when you get a crash dump from your customer, its always good to know how to reproduce the crash and point out where the actual crash happens. Today I was debugging some bug with my lead, I found this very useful: Here are the steps: First of all open the windows
This is especially useful when you want to use someone else’s dlls. 1) Open the dll in windows dependency viewer: You should see the following, if its a COM dll. This basically is related to COM. If you go through COM tutorials you will know about this. 1) next open the dll you need in
If you have a situation as above or in clear words If an application has a string localized to multiple languages and mapped to the same ID in each language, the correct version of the string might not be loaded on Windows 95 or Windows 98 using the Win32 function ::LoadString. To load the correct
Recently I had to integrate cppunit and teamcity on linux for running my unit tests. First of all you can either link against and compile cppunit libs to run the tests OR the lazy way to do this is just install cppunit. Do it this way: $ apt-cache search cppunit libcppunit-1.12-1 – Unit Testing Library
As mentioned in my previous post, we do the same thing but we do it using pthreads. we can do this in two ways. suppose your writing this code for yourself, and its not going to be distributed, meaning you really dont care about version of pthreads while linking, you can directly define pthreads. pthread_create(
One of the instances, your customers or yourself would be using call backs when you need to call a method asynchronously and receive the feedback. When I tell asynchronously, it means like you want to read a huge file[> 100MB] and parse them. I know this consumes a huge amount of memory. Use file handles
I learnt this from my manager. DebugBreak is powerful tool you can use when debugging applications. I had this scenario where I need to use a java app which was internally calling C++ methods, basically JNI functions. The error in question was in the C++ side, so not really an option to use debugger. Therefore
TeamCity treats equally all agents no matter if they are installed on the same or on different machines. However, before installing several TeamCity build agents on the same machine, please consider the following: * Builds running on such agents should not conflict by any resource (common disk directories, OS processes, OS temp directories). * Depending
As mentioned previously, many legacy Windows applications were created so you could access parts of the file system and registry that are now locked in Windows Vista, and many of these applications are not being immediately updated. However, Microsoft has devised an interesting solution within Windows Vista to provide backward compatibility so that legacy software
Above is the error you would be getting when trying to install Microsoft System Center Configuration 2003. I have attached the screenshots of enabling and installing bits. 1) Goto Add remove programs 2) click on windows components 3) goto IIS and double click that.
1) First of all make sure, the exe is running for which you need to know if the dll is loaded. 2) Use the windows API: typedef DWORD ( WINAPI *GETMODULEFILENAMEEX) ( HANDLE, HMODULE, LPTSTR, DWORD ); 3) Open the process: HANDLE myprocess= OpenProcess( PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, FALSE, myProcessID); Over here you would need to
Description of Listbox: Provides the functionality of a Windows list box.

Paste this exactly to get your MD5 key: C:Program FilesJavajdk1.6.0_20bin>keytool.exe -list -alias androiddebugkey – keystore “C:Documents and Settingstest.androiddebug.keystore” -storepass android -keypass android Also there is a bug in eclipse, where in you will get a greyed out map with only tiles. Use this to correct that: The solution was to set the “Custom debug keystore”
Below search method will be useful when you need to find a window with no caption. FindWindow will not work correctly in such a instance. You can make use of the below method to do that. //get the handle to the top window HWND h = ::GetTopWindow(0); while ( h) { TCHAR buf[100]; ::GetClassName( h,
Installing AntiVir (example for AntiVir Server) For using Avira AntiVir Server/ Professional v.3 with AntiVir Guard, we recommend and support dazuko3/dazukofs. The installation script will also install dazuko3, if it detects the needed build components on your system. If the installation script cannot detect a supported linux kernel version, you can only install Avira AntiVir
When trying to run a subversion or svn service, we get this error stating the service is not running, this is because of the way you create the service: Below are the right and wrong way to create it: WRONG WAY: F:Program FilesSubversionbin>sc create svnserver binpath= “F:Program FilesS ubversionbinsvnserve.exe –service -r F:Dev FilesRepository” displayname= “S
Some tools which I really find helpful are: a. Multimon – Support for multiple monitors b. Process Monitor c. Process Explorer d. Desktops – Desktops allows you to organize your applications on up to four virtual desktops. e. OleView – For COM purposes f. Spy++ – For windows GUI handling g. Resource hunter – Reading
Goto your res folder as shown in image below add a background image. After adding a background image, goto the main.xml and add the below text: <ImageView android:layout_height=”wrap_content” android:layout_width=”wrap_content” android:src=”@drawable/background” /> Note: Do not add the extn to the image name, it wont recognize the file and give an error. Next goto your main class
I had an opportunity to use CListbox. The scenario was that I had to pre populate the list box and display it in a pop up window. Its very to use listbox when using it in a parent window but when you want to display it in a standalone pop up window, you would get
You would be getting this error if you tried to use CArray in VC 6. You would need to use some other way to get the values selected in listbox. In my next post I would be showing how to use two different ways to access a CListBox.
One of the simplest ways to detect a leak in your code would be to use debugCRT. Simple usage: a. Create you project in visual studio b. run the project in debug mode, then only you will find the memory leak dumps int main() { _CrtSetDbgFlag(_CRTDBG_CHECK_ALWAYS_DF | _CRTDBG_ALLOC_MEM_DF); //below call will break where the leak
Below is the code to create a registry key in VC++. I used visual studio 2008 for this(VC9) RegCreateKeyEx is the command to create the key. More documentation can be found online@ msdn. #include “stdafx.h” #include “Windows.h” int _tmain(int argc, _TCHAR* argv[]) { HKEY hOutKey; RegCreateKeyEx(HKEY_LOCAL_MACHINE, L”SOFTWARE\ABC\Registration\addkey”, 0, 0, REG_OPTION_NON_VOLATILE, KEY_ALL_ACCESS, NULL, &hOutKey, NULL); return
I recently came across this site where they have reviewed the much awaited nokia n8. What I am amazed is that these fools reviewed an unfinished and untested product and declared the phone worthless. Any sensible person would not review an untested and unreleased product. God save their readers. As for the stolen phone, it
lets take a look at how to compare two systemtime variables but using Filetime to do so. We make use of the utility method CompareFiletime to do this. 1) store the systemtime in a variable 2) convert it into filetime. Use this method SystemTimeToFileTime(&systemtime1, &filetime1) SystemTimeToFileTime(&systemtime2, &filetime2) 3) Compare the filetimes using the method CompareFileTime(&filetime1,
The easiest way to do this would be to use the option KEY_ENUMERATE_SUB_KEYS when you open the registry key. This option would read both the 32bit and the 64bit registry keys.
This happens usually because in your visual studio vc6 compiler options you would have set the library files path to “Microsoft platform SDKs” , which uses the newer library files. Goto the option again and then set to “Microsoft SDKs” which is set to older SDK. this will help to solve your problem.
I almost gave up searching for this option when I was coding on something. I tried using spy++ and wininspector to do this. These were pretty helpful but not that I could get the end result. Consider this scenario, you have a icon on the taskbar. You need to right click and select an element
