19 Nov 2017 ... In this tutorial, I am going to explain you how to extract text from PDF file using iTextSharp with C# in ASP.NET. Below is step by step tutorial. You ve already seen how HQL injection can be used to cause a DoS attack and bring your system down. However, there are other ways you can be vulnerable to a DoS attack even if you avoid using String concatenation to build queries. One of the most common ways is through pagination. As you ll recall, GORM methods like list and the dynamic finders accept parameters such as offset and max that allow you to paginate through the records available in the database. Listing 14-7 presents an example of a simple list action that does this. Listing 14-7. Listing All Albums def list = { if(!params.max) params.max = 10 [albumList: Album.list(params)] } As innocent as it may seem, the code in Listing 14-7 is vulnerable to a DoS attack. The reason is that the code doesn t set the maximum value of the max argument. An attacker could pass a max value of 1000000, and you could end up with a million records loading and the same OutOfMemoryError and thread blocking issues we mentioned earlier. Ouch! A better solution is to ensure that you constrain the value of the max parameter passed to a query to not exceed a specific value. Listing 14-8 shows an example implementation that ensures the max parameter can only ever reach 100. Listing 14-8. Constraining the Maximum Value for Pagination def list = { params.max = Math.min( params.max .toInteger() : 0, 100) [albumList: Album.list(params)] } As you can see from the code in Listing 14-8, you can use the Math.min method to get a safe maximum value to use when paginating data. We re not done with potential vulnerabilities just yet, though. In the next section, you ll look at one that affects data binding. c# read pdf file text: Extract Text from PDF in C# - C# Corner itextsharp read pdf line by line c# How to extract text from PDF file in C# - YouTube

Many web frameworks, including Grails, allow you to bind the data of incoming request parameters to objects In the case of Grails, these are typically domain instances Data binding was covered in depth in 4, but just as a reminder, with Grails it can be done with the following constructor: def album = new Album(params) or alternatively using the properties property of an existing domain instance: def album = Albumget(paramsid) albumproperties = params In many scenarios, this is not a problem, because a trusted source may be performing the update However, in some cases, using this technique can be undesirable Consider, for example, a scenario where you used a simple flag on a User domain class to signify whether the User is an administrator: class User { .. boolean administrator } Administrators have far-reaching powers over the system that only a select few are allowed to have. c# read pdf text itextsharp Extract Certain Text from PDF Document Using C# Code - Yiigo

For example, a Microsoft Word document might have welldefined page breaks, and that correlation is clear. However, an Excel workbook might have multiple worksheets, and no defined breaks within those sheets. Columns might or might not be expanded so that all data is visible, and they might even be hidden. How many pages (and therefore how much data) comprise the workbook This is difficult to guess. When handling electronic data, it might be possible to estimate the number of database records by counting files, but it s much more difficult to estimate the database s final size. When a collection consists of electronic files, you can estimate the number of pages using the values in Table 5-3 as a guide. Table 5-3.
