28 Sep 2014 ... Password - Protected PDF File Using ASP.Net C# . This article shows how to ... to a PDF file as well as some methods to protect generated files. Notice that I m looking at permissions on the containing folder rather than individual .dtsx (package) files. It is possible to set the permissions on each package file, but as far as I m concerned, limiting access to the container that holds them is the way to go. On the Security tab of the folder properties window, clicking Add... allows me to add my two new SSIS package users. It also allows me to specify the permissions for the folder. With the two users I ve added, I need to select them in turn from the Group or user names pane, then choose their permissions below. I start by deselecting (or unchecking) the values for everything except List Folder Contents and Read for the read-only user and List Folder Contents, Read, and Write for the read/write user. Depending upon how tightly I want to screw down the folder s security, I could remove the other groups or users that have access to it and just leave the SSIS users. There are obvious flaws to creating new users and assigning them permissions. It might be fine to do this in smaller development teams, but it really isn t all that secure, is it Somehow keeping assigned user names without having to configure each of them on the folder would be a good thing. Group-based security is one answer. Creating user-group objects is just as easy as creating a new user, with less administrative overhead.

Creating an SSIS Read Only Users group With a new custom-made group created, I can assign group permissions instead of assigning user permissions on the Package Store folder. All I need to do now is assign individual users to the group, and I no longer need to modify folder permissions each time a user needs access to a folder. Figure 13-10 shows the operation to assign group permissions to a folder rather than user permissions. Going back to the user-administration console in Figure 13-6, I can select each user that I want to add to my new group and, as Figure 13-11 shows, add them to a chosen group. If you have more than a couple of users to add, however, this can become real old real fast. merge pdfs into one c#: Merge PDF Files with New Method in C# - E-iceblue how to open password protected pdf file in c# itextSharp .text.pdf.badpasswordException PdfReader not opened ...

In my experience, many of the companies that have started to use SOA have seen improvements in their ROI. But so far none of these companies have implemented SOA for all their business activities. They often do new development with an SOA mindset and implement business logic and processes as services, but they still have many applications and systems that are not implemented as services. They have not converted all their processes to services either, so maybe it is too early to tell. We might need to wait a few years before we really see ROI improvement. But once we start letting SOA influence all IT issues in our organization, we make certain that the ROI will be great. An alternative is to look at the properties of the group that has been added in my case SSIS Read Only Users and add relevant users from the Members tab. You can see this in Figure 13-12. public boolean authenticate() { log.info("authenticating {0}", credentials.getUsername()); //write your authentication logic here, //return true if the authentication was //successful, false otherwise if ("admin".equals(credentials.getUsername())) { identity.addRole("admin"); return true; } return false; } } c# create pdf with password Password protecting a PDF file - Stack Overflow

There's no PDF support in C# , you need to find a library to do that, probably paid, but free ones exist. To better understand what a service is and why we must think of architecture in a slightly different way than we did with object-oriented programming and components, we ll now look at the four important tenets that Don Box, of Microsoft s Windows Communication Foundation team, identifies as crucial. Figure 13-12. The easy way: assigning users to groups And we re done. I can add developers to an SSIS Read/Write group, and project managers or other lower-access users to the SSIS Read Only Users group. For brevity I have created only two groups, but of course, depending on your circumstances, you can create as many groups as you need. An entirely different set of techniques and settings must be used if packages are stored in SQL Server. Now, log in as admin, and try to add a product as shown in Figure 10-4. Note that Seam has figured out that the name is required (from @NotEmpty) and that the price is also required (from the fact that it is a primitive double, not a Double and thus can t be null). When stored in SQL Server, packages are placed in the sysdtspackages90 table of the msdb database. Access to this repository is incredibly limited and is performed through a number of stored procedures including one that retrieves a list of the stored packages. Without assignment to the correct SQL Server role, access to the repository table will be denied. This is handy to know it s information that can be used to secure packages. Three msdb database roles control this access, as shown in Table 13-1. Table 13-2 shows the permissions applicable to each of the stored procedures used to access the SQL Server Package Store. It serves as a graphic demonstration of the levels of access available to each role.
