Telerik RadList Box Checkbox Items check all or uncheck all

Aspx page: I bound the lstLocations dynamically. So it look like as below.

Capture

<telerik:RadListBox ID=”lstLocations” runat=”server” CheckBoxes=”true” Width=”520px”
Height=”130px”>
</telerik:RadListBox>

// Select All checkbox buttons
<asp:CheckBox CssClass=”CBFull” ID=”chkSelectAll” runat=”server” Text=”Select All”
onclick=”javascript:return ToggleAllLocations(this);” />
// Add below function in javascript function



function ToggleAllLocations(checkBox) {
             //ctl00_ContentPlaceHolder1_RadDockLocFilter_C_lstLocations is a client id of radlistbox                   
            var listbox = $find("ctl00_ContentPlaceHolder1_RadDockLocFilter_C_lstLocations");

            var j = listbox.get_checkedItems().length;

            if (!document.getElementById(checkBox.id).checked) {
                for (var i = 0; i < j; i++) {
                    listbox.get_checkedItems()[0].uncheck();
                }
            }
            else {
                for (var i = 0; i < listbox.get_items().get_count(); i++) {
                    var item = listbox.getItem(i);
                    listbox.trackChanges();

                    item.set_checked(true);

                    listbox.commitChanges();

                }                                           
            }
            return true;
        }


Google cloud Messaging (GCM) for Android App and Asp.Net server app

At the Google IO 2012, the beta version of Android push notifications system called C2DM was replaced by Google Cloud Messaging (GCM). GCM has many new features over the existing system. Refer to this document for details of the differences and details about migrating your existing systems from C2DM to GCM.

To get started, download the Extras > Google Cloud Messaging for Android Library from the Android SDK.This library provides the jars to simplify the development on both the server side and client side.

From the Google API console page, create a new project and generate the API key. Refer this page for complete details.

Google provides the sample apps in the SDK by default, you may download a very basic version of them containing only the code discussed in this tutorial from here.
The same application is also available on play store here.

How to execute store proc and create batch file for windows task scheduler or create a job in SQL server Agent.

Example1: Full backups of all databases in the local named instance of SQLEXPRESS by using Windows Authentication

// Sqlbackup.bat

sqlcmd -S .\EXPRESS –E -Q “EXEC sp_BackupDatabases @backupLocation=’D:\SQLBackups\’, @backupType=’F'”

Example2: Differential backups of all databases in the local named instance of SQLEXPRESS by using a SQLLogin and its password

// Sqlbackup.bat

sqlcmd -U SQLLogin -P password -S .\SQLEXPRESS -Q “EXEC sp_BackupDatabases @backupLocation =’D:\SQLBackups’, @BackupType=’D’”

Note: The SQLLogin shouldhave at least the Backup Operator role in SQL Server.

Example 3: Log backups of all databases in local named instance of SQLEXPRESS by using Windows Authentication

// Sqlbackup.bat

sqlcmd -S .\SQLEXPRESS -E -Q “EXEC sp_BackupDatabases @backupLocation=’D:\SQLBackups\’,@backupType=’L'”

Example 4: Full backups of the database USERDB in the local named instance of SQLEXPRESS by using Windows Authentication

// Sqlbackup.bat

sqlcmd -S .\SQLEXPRESS -E -Q “EXEC sp_BackupDatabases @backupLocation=’D:\SQLBackups\’, @databaseName=’USERDB’, @backupType=’F'”

Similarly, you can make a differential backup of USERDB by pasting in ‘D’ for the @backupType parameter and a log backup of USERDB by pasting in ‘L’ for the @backupType parameter.
