ASP.NET Web PDF Document Viewer/Editor Control LibraryIf you want to find out whether a particular permission is set, use one of the versions of ApplicationPermissionsManager.getPermission(). You must provide one of the permissions from Table 9-1. You will get back the current setting. ApplicationPermissions.VALUE_ALLOW means access is granted. ApplicationPermissions.VALUE_PROMPT means access will be permitted if the user confirms. ApplicationPermissions.VALUE_DENY means access is forbidden. The following snippet demonstrates how you can check to see whether a permission is properly set before starting a potentially restricted operation. code 128 vb.net free, vb.net code 39 generator in vb.net, vb.net generate data matrix code, microsoft reporting services qr code, ssrs upc-a, free barcode generator dll for vb.net, c# remove text from pdf, replace text in pdf c#, ssrs pdf 417, c# remove text from pdf,The solution to the HTTP POST problem is simple, but it requires the ability to use the XMLHttpRequest object. In this section, you ll learn how to convert the original application to use the new architecture. The original and new HTML pages will be illustrated at a code level. The idea of this section is to illustrate the conversion. The Original HTML Form The original HTML form used an HTTP POST, and is illustrated as follows: <html> <head> <title>Title</title> </head> <body> <form action="/ajaxrestrecipes/architecture/forms/Posted.ashx" method="POST"> <input type="text" name="example" /> <input type="submit" value="Submit" /> </form> </body> </html> The bold form attributes show that when the Submit button is pressed, the URL /ajaxrestrecipes/architecture/forms/Posted.ashx is called using a POST. From a Representational State Transfer (REST) perspective, the URL only accepts a single verb, POST. This is the heart of the problem in that you cannot retrieve the page using a GET, which is the default HTTP verb used by a browser. The Converted HTML Form The converted HTML form uses the same HTML constructs, but it delegates the POST to an XMLHttpRequest and retrieves the next page using a GET. The following code shows the converted HTML form: <html> <head> <title>Title</title> </head> <script language="JavaScript" src="/scripts/jaxson/common.js"></script> <script language="JavaScript" src="/scripts/jaxson/communications.js"></script> <script language="JavaScript" src="/scripts/jaxson/commonmorphing.js"></script> <script language="JavaScript" type="text/javascript"> var representations = { }; function OnSubmit() { var obj = RepresentationManager.iterateHtml.get( representations, document.getElementById( "form")); var stringToSend = Ops.serializeCGI( obj); This is where you can view the WWN, create hard loops, set speeds to static, and define the topology Generally you can leave the default settings unless you ll be using arbitrated loops in your FC topology (see Figure 4-8) These settings will be detected automatically, for the most part, but sometimes you may need to assign them manually For example, if you use an FC switch that doesn t detect the speed of the FC on the Xserve RAID automatically, you may need to set this value by hand.. Under the Performance tab you can customize certain features to enhance the performance of the Xserve RAID (see Figure 4-9) in an Xsan environment. You can: Enable Controller Write Cache (recommended for performance only if a UPS provides power protection to the unit) Enable Host Cache Flushing (recommended to have disabled for best performance) Enable or disable the drive write cache (recommended for performance only if a UPS provides power protection to the unit) Set read prefetch to 1, 8 or 128 stripes for each controller ApplicationPermissionsManager permissions = ApplicationPermissionsManager.getInstance(); int currentSetting = permissions.getPermission( ApplicationPermissions.PERMISSION_FILE_API); if (currentSetting == ApplicationPermissions.VALUE_ALLOW) { // We can access the file here. } Now you ll want to set up the RAID system s LUNs. The admin utility refers to these logical portions of an Xserve RAID as arrays. You assign each a RAID level according to your requirements. The Xserve supports levels 0, 1, 3, 5, and 0+1. With Xsan you should use level 1 for your metadata LUN and 5 for data LUNs. In the admin utility, select the Xserve RAID on which you ll be creating a LUN and click the Create Array button in the utility s toolbar. When prompted, enter the management password for the Xserve RAID and click OK, then select the RAID level, as shown in Figure 4-10. var asynchronous = FactoryHttpgetAsynchronous(); asynchronoussettings = { onComplete : function(xmlhttp) { locationhref = documentgetElementById( "form")action; } } var obj = new Object(); objdata = stringToSend; objlength = objdatalength; objmimetype = "application/x-www-form-urlencoded"; asynchronouspost( documentgetElementById( "form")action, obj); } </script> <body> <form id="form" action="/ajaxrestrecipes/architecture/forms/AjaxPostedashx" method="POST"> <input type="text" name="example" /> <input type="button" value="Submit" onclick="OnSubmit()"/> </form> <div id="output"></div> <div id="error"></div> </body> </html> The important modified parts of the HTML page are shown in bold The overall change has been to convert the input type of submit to button, and have the button implement the click event The click event calls OnSubmit and is responsible for doing a POST and GET When OnSubmit is called, the function RepresentationManageriterateHTMLget is called, which is used to extract the state in the HTML form elements.
