XCB - how to launch and show an application (terminal for example)?

Hello, everyone!
I'm trying to learn XCB, but all of the tutorials I've found so far do not explain how can XCB used as a window manager.
I understand how to draw a single window and add a string to it, but how can I launch something from it and show it to the user?

XCB is an implementation of the client side of the X protocol. In other words, it's a library for writing X applications and window managers; it's not a window manager itself.
If you're interested in learning about how window managers launch applications, you probably want to read up on fork() and execve(). This is essentially how all processes are created on a Linux system (from init, a shell, window manager, etc.).
Also, if you're interested in learning how window managers work, a good place to start might be tinywm. It's a single C file intended to be the bare minimum to be a window manager. It uses Xlib though, not XCB, but at this point your goal should be to understand the concepts. Somebody out there may have created an XCB version by now, anyway...

I have multiple images in my App folder. I want to use and show those images dynamically in windows phone 8 map application

There are a lot of different ways to do this. One simple method is to use a switch statement when creating your pushpins and based on some property in your data, select the icon you want to use and create your pushpin accordingly.

How to design and implement an application that reads a string from the user and prints it one character per line???

This is so trivial that it barely deserves the words "design" or "application".
You can use java.util.Scanner to get user input from the command line.
You can use String.getChars to convert a String into an array of characters.
You can use a loop to get all the characters individually.
You can use System.out.println to print data on its own line.
Good luck on your homework.

A good book to start with is Enterprise JavaBeans by Monson-Haefel (O'Reilly press). It covers deployment of EJBs on J2EE servers. Also check out sites specific to your server, sometimes they have specific requirements (like Weblogic).

Hi,
You can use: startManagedWebLogic.sh, it is in your domain directory and you have to execute it in this way
./startManagedWebLogic.sh managedServerName http://adminServerHost:adminServerPort
For instance, in my case I use:
unixserv01:/webportal/domains/appServerWeb/bin>startManagedWebLogic.sh managedServ01 http://pelma3w3per01.mesaperu.next:7001
You have to run it on the machine where the managed server was installed.
Best regards,
Raúl

Yosemite mail v8.0 not showing how many messages are in a mailbox. For example inbox. Before upgrading it used to show how many messages you had in your inbox. anyone know how to switch "on" the number of messages?

Yosemite mail v8.0 not showing how many messages are in a mailbox. For example inbox. Before upgrading it used to show how many messages you had in your inbox. anyone know how to switch "on" the number of messages? Or has this feature been removed?

Agreed! This feature was very useful. If you find out how to turn it on, please let me know.
Apple, there is plenty of room in the window header all the way across on both sides of the word "Inbox". It's important to know many messages are in the Inbox. It provides a progress meter when you're cleaning out mail and striving for inbox zero.

How to set and resent reconcilation a/c for Assent a/c

hi
how to set and resent reconcilation a/c for Assent a/c
amk

You are permitted to post the recon account undercertain special circumstances :
USe the transaction codes OAMK and OASV.
Kindly read the SAP on line documentation before making a postings directly to the recon account.
Definition of the Reconciliation Accounts
You are not allowed to manually post to the reconciliation accounts for Asset Accounting in Financial Accounting. Normally, you designate the corresponding General Ledger accounts in Financial Accounting as reconciliation accounts. This change, however, can no longer be made in Financial Accounting, once these accounts already have balances from the legacy data transfer. However, you can use a special report to assign these accounts the status of reconciliation accounts in Financial Accounting (in Customizing for Asset Accounting, choose Preparing for Production Startup ® Production Startup ® Set Reconciliation Accounts).
There is another report for removing this specification (Reset Reconciliation Accounts).
Subsequent Correction Postings to Reconciliation Accounts
Suppose you have already defined the asset G/L accounts in Financial Accounting as reconciliation accounts, but still need to transfer balances to these accounts, or make corrections. You can make correction postings to these reconciliation accounts with a special posting transaction in Customizing for Asset Accounting (Transfer Balances), using posting key 40 or 50. You can only postings to those accounts in a company code with implementation status (Customizing for Asset Accounting, choose Preparing for Production Startup ® Production Startup ® Activate Company Code).

All Apple iTunes Store accounts must have a valid form of payment set up. Even for free apps and updates. The Payment Declined message comes from your card issuer or payment source; Apple is just a pass-through for the message. You need to find out why your issuer is declining your card.

After altering the "Processes" list in Task manager, almost all of my programs show the iTunes icon, and when I click on, for example, Firefox, iTunes will load. Uninstalling iTunes restores the normal loading of other programs, but re-installation of iTunes makes the problem recur. Any answers?

First I'd set up a System Restore point. Then try applying the LNK registry fix from the following document:
File Association Fixes for Windows 7
Does that get your icons back to normal?

Try connecting the iPad to the computer that you do not want to WiFi sync with and uncheck the WiFi sync option in iTunes. Then click on Apply. Reboot the iPad and see if that does the trick.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
