Including (Linking/Embeding) Resources to Executables

With the Borland’s Resource Compiler we have created the AboutDelphi.res resource file. The next step is to add the following compiler directive to a unit in your project, immediately after the form directive (below the implementation key word). Read the rest of this entry »

hi all delphi readers, Games and other types of applications which use multimedia files like sounds and animations must either distribute the extra multimedia files along with the application or embed the files within the executable.
Rather than distribute separate files for your application’s use, you can add the raw data to your application as a resource. You can then retrieve the data from your application when it is needed. This technique is generally more desirable because it can keep others from manipulating those add-in files. Read the rest of this entry »

Hello alldelphi.com users, we meet again today i want to show you some interesting snippet

Suppose you have a data-critical type of application where you would not want a non-authored user to work with the data. Such an application could automatically log out the current user if no user activity has taken place in a lengthy time.

To track a user’s idle time you could hook keyboard and mouse activity. Note, however, that installing a system-wide message hook is a very invasive thing to do and should be avoided if possible, since it will require your hook DLL to be loaded into all processes. Read the rest of this entry »

The real simplicity to this function actually comes from the hard work done by the encryption classes TDCP_cast256 and TDCP_sha1 which work seamlessly together to encrypt my string for me. To get a better understanding of how the encryption works lets take a look at some of the method calls used from the encryption classes:

TDCP_cast256.Create(Self) - The constructor method of the TDCP_cast256 class returns an object of type TDCP_cast256. Using this object we can call the EncryptString method. Read the rest of this entry »

Hello, www.alldelphi.com readers, today i want to talk about Encryption, Cipher and Hashes after googling for some times i found some article that interesting enough that i want to share to you all alldelphi.com readers so here it go.
