HKMessageReceiver gives you a non visual component, that added to a form, makes it able to receive messages sent or posted at application handle. It has an event that is called when all WM_USER messages are broadcast.

This way you can give large programs polymorphism, and make and forget about forms or datamodules that do something when something has changed in your program. If the form is not open, no harm done, the message is ignored.

If you have a program that when something is done in one form or datamodule, that should be known any where in your program, I think this very simple component is necessary.

Finally, Delphi developers have a reliable way to eliminate embarrassing spelling errors in their applications. Spelling errors make your application, that otherwise maybe a great program, look unprofessional. This could ultimately cost you sales.

MisSpel for Delphi installs into the Delphi IDE MainMenu. MisSpel for Delphi allows you to spell check your source code (strings and or comments) or components laid out on a form or datamodule.

PDFtoolkit is a useful tool designed for Borland Delphi and Borland C++Builder to manage, manipulate, view, print, enhance PDF documents and process PDF eForms.

PDFtoolkit supports viewing and printing, filling and reading of PDF forms, compressing, securing, appending and merging of multiple PDF documents, stamping, building Table of Contents, setting bookmarks, and many more functions that can be performed on PDF documents. PDFtoolkit operates on existing PDF documents and can even create new ones by extracting pages from existing documents.

With the help of PDFtoolkit powerful PDF document management functions can be performed from within the business applications, making the applications more efficient and independent of external software.

PDFtoolkit provides VCL components to link to the PDF documents that need to be managed. The developer can place the PDFDocument component on a Form or DataModule, set properties and then call methods to fill or read form values, compress, secure by setting password, append or merge multiple PDF documents, rubber stamp as ‘Confidential’, ‘Draft’, etc, add bookmarks and perform many more tasks related to PDF. The final output can be received in a memory stream or a disk file.

The screen shot on the left shows how three existing PDF documents can be opened, merged, rubber stamped, secured with a password and saved to disk as one document. The screen shot on the right shows the new, merged PDF document.

PDFtoolkit supports a whole range of PDF document management and manipulation functions that enable a developer to implement all PDF management tasks right with in the application. Following is a partial list of the functions supported:

· Merge a list a PDF documents by just proving the names of the documents.
· Insert pages from one document to another by specifying a range of pages in the source document and the point at which the pages should be inserted in the destination document.
· Append pages to the end of one document by specifying a range of pages in the second document.
· Delete pages from a document by specifying a range of pages to delete.
· Extract pages from one document by specifying a range of pages to extract into the second document.


Once the operations are performed by calling any of the functions the document can be encrypted with owner and user password, and written to disk or memory in compressed or uncompressed form.

Access permissions can also be set on the user password to allow or disallow printing, copying of text and graphics, modifying of document and so on. PDFtoolkit also handles encrypted PDF documents when appropriate passwords are provided; taking care to allow only the operations the user is permitted to perform. If the owner password is provided then all operations are allowed.

Here are some key features of "PDFtoolkit VCL":

· View and Print PDF documents
· Fill and Read PDF forms (also known as AcroForms)
· Append and Merge multiple PDF documents
· Secure PDF documents with passwords and set access permissions
· Insert pages from one PDF document to another
· Extract pages from a PDF document to make new ones
· Set thumbnails
· Set bookmarks with unlimited nesting levels Make existing documents easier to navigate and browse by building a Table of Contents with links to pages by topic names.
· Set watermarks and rubber stamp documents Designate a document as “Confidential” or “Draft” by specifying text and images to stamp on each page of the document, or underlay the company logo as a watermark.
· Save final document to memory, HTTP Response, or disk
