Chuyển đổi tài liệu PDF sang Word 01:07' 22/11/2005 (GMT+7) Word đã trở thành "vua" của các bộ soạn thảo văn bản. Hầu hết các văn bản đều được định dạng và in bằng Word. Tuy nhiên, bạn có một số văn bản bằng PDF (Portable Document Format), bạn muốn chỉnh sửa các tài liệu này trước khi in ấn. Acrobat Reader không có khả năng chỉnh sửa văn bản, còn Acrobat thì giá cả hơi "mắc" mà lại đòi hỏi tài nguyên khá lớn. Vậy, có phần mềm nào có khả năng chuyển đổi định dạng từ PDF sang Word mà vẫn giữ nguyên định dạng, giá cả cũng chấp nhận được và lại tiêu tốn ít tài nguyên hệ thống ? Thực ra, để giữ nguyên các định dạng tài liệu sau khi chuyển đổi là rất phức tạp và khó khăn. Đến ngay như phần mềm Acrobat, khi chuyển đổi tập tin PDF sang Word cũng không được hoàn hảo. Tuy nhiên, nếu bạn đã từng sử dụng qua phần mềm SolidPDFConverter của hãng Solid, phần mềm này thật tuyệt vời ! Các tài liệu phức tạp gồm các nội dung văn bản, hình ảnh, bảng tính . vẫn giữ nguyên định dạng sau khi chuyển đổi sang Word. VietNamNet đã thử nghiệm chuyển đổi tài liệu phức tạp gồm hình ảnh, bảng biểu , đồ hoạ, văn bản xen kẽ, khoảng 70 trang bằng Adobe Acrobat và SolidDPFConverter. Kết quả là SolidPDFConverter cho tốc độ chuyển đổi tài liệu nhanh hơn và giữ được định dạng tài liệu gốc chính xác hơn Acrobat. Tuy nhiên khi chỉnh sửa một số văn bản kết hợp trong các bảng biểu, đồ hoạ cho kết quả chưa được tốt lắm. Mặc dù vậy SolidPDFConverter vẫn là công cụ đáng giá với mức giá tương đối rẻ so với phần mềm đồ sộ tương đối "nặng ký" Acrobat. SolidPDFConverter có đồ thuật đơn giản sẽ giúp bạn chuyển đổi định dạng .pdf sang định dạng .doc nhanh chóng chỉ với 5 bước: Bước 1: Chọn định dạng Bạn hãy chọn tập tin PDF cần chuyển đổi ngay trong khung tìm tài liệu của SolidPDFConverter. Hãy sử dụng tùy chọn: • Flowing: Với chế độ này, các trang vẫn giữ nguyên cách trình bày, định dạng, đồ họa và các dữ liệu văn bản. • Continuous: Với chế độ này cái mà bạn cần chỉ là nội dung chứ không cần chính xác cách trình bày của tài liệu. Ví dụ: giả sử mục đích là bạn cần nội dung cho những trang có kích thước khác hoặc các phần mềm trình diễn như Power Point hoặc chuyển sang định dạng HTML. Chế độ này sẽ sử dụng cách phân tích trình bày trang và cột để xây dựng lại thứ tự các văn bản nhưng chỉ phục hồi định dạng đoạn, đồ họa, và dữ liệu văn bản. • Plain Text: Nếu bạn chỉ cần văn bản mà không cần định dạng hay trình bày, bạn hãy sử dụng Plain Text. Plain Text sẽ phục hồi các định dạng kí tự, đoạn hoặc đồ họa nhưng chỉ phục hồi văn bản bằng phân tích cột và trình bày trang. • Exact: Nếu bạn cần một tài liệu Word trông giống hệt như tài liệu PDF? Bạn cần thay đổi nhỏ các tập tin này? Exact sử dụng các TextBox của Word để đảm bảo chắc chắn văn bản và đồ họa vẫn giống y nguyên bản PDF gốc.Chế độ Exact không nên sử dụng nếu bạn cần chỉnh sửa rất nhiều nội dung từ Train your doubt Train your doubt Bởi: Joe Tye “Doubt is torture If we give ourselves fully to something, it will be clearer when it might be appropriate to quit It is a constant test of perseverance Don’t listen to doubt It leads no place but to pain and negativity.” Natalie Goldberg: Writing Down the Bones Between 1902 and 1908, the German Rainer Maria Rilke wrote a series of letters to a young poet that have since been published (and are still in print) The young poet was wracked by self-doubt about the quality of his work Rilke responded that he needed to train his doubt, to teach it to ask better questions That is great advice when your world turns upside down The dictionary definition of doubt gives it two meanings: a feeling of uncertainty a lack of conviction If the doubt you are feeling is of the first variety, what you can to reduce your uncertainty level with more research, but then accept the fact that some things must remain uncertain The young poet can study the masters, write and re-write his poems, but he cannot dictate how the critics will respond If your doubt is of the second variety, a lack of conviction, ask yourself whether that is because you really don’t believe in the cause, whatever it is (your job, your half-written book, your marriage, your diet and fitness program, etc.), or rather that you simply are not willing to pay the price, make the sacrifice, and the work In such cases, doubt is often just an excuse for laziness and cowardice As Goldberg says, doubt is a constant test of your commitment and perseverance Train yours to work for you and not against you by teaching it to ask empowering questions and to stop pestering you with disempowering questions One more thing: virtually every major breakthrough in the history of the world has come from someone acting upon doubt From Copernicus doubting the conventional wisdom of a geocentric universe to J.K Rowling doubting the conventional wisdom that an 1/2 Train your doubt unemployed single mother can’t become a successful author, people who act upon their doubt have changed the world So if you are feeling overwhelmed by doubt, ask yourself if it might not be that you are on the verge of some sort of breakthrough yourself 2/2 Count Down Your Age This page intentionally left blank Count Down Your Age Look, Feel, and Live Better than You Ever Have Before FREDERIC J.

Don't be one of them: Back up your PST regularly, as often as once a day or once a week. People who back up Outlook typically use Import and Export to back up their Outlook data or move it to a new computer. That's the wrong way to do it. Import and Export imports and exports only Outlook items; it doesn't touch custom forms, views, or other hidden items in the folders. When you want to back up your data or move it to a new computer, find the PST and copy it. Unless you moved your PST to a new location, Outlook stores the PST at C:\Documents and Settings\username\Local Settings\Application Data\Microsoft\Outlook. Close Outlook, find the file, and make a copy. To make it easier to back up your PST, move it to your My Documents folder. Close Outlook, find the PST, and move it. Reopen Outlook and when it complains about the missing PST, browse for the PST in the new location. There's little reason to back up your HTTP and IMAP PSTs because they contain copies of the messages still on your server. You need to edit the Registry to move them, but because Outlook often re-creates new PSTs in the default location, it's not recommended. The Outlook folder under Local Settings contains Offline address book files (if you use an Exchange Server account) and extend.dat. Neither of these files needs to be backed up. Because extend.dat contains information about installed add-ins, using it on other machines could cause errors if the add-in isn't installed. If the Outlook folder isn't visible, enable Show Hidden Files and Folders using Windows Explorer's Tools, Folder Options, View. When using Windows Search, always use the Advanced option to Search All Hidden Files and Folders. The other Application Data folder in your Windows user profile, C:\Documents and Settings\username\Application Data\Microsoft\Outlook, contains the remainder of the Outlook data you might want to back up. In most cases, the customization files in this folder path use the name of your profile. Each profile has its own set of files. The exception is the toolbar customization file: outcmd.dat. The same custom toolbars apply to all profiles used with your Windows user account. Copies of outcmd.dat should be made after creating toolbar customizations. Because it's not profile-specific, you can use this file on any machine with any profile. • XML— Stores your navigation pane settings. This file can be backed up or deleted when you want to remove customizations and Outlook will create a new default XML. • NK2— Stores the AutoComplete addresses seen when you type addresses into the To field. This file does not need to be backed up. Delete it to start with a new AutoComplete list. • SRS— Send and receive settings. This file can be backed up, although it's most useful only when the same accounts are restored. Any of these files can be renamed to match the name of any profile and, in most cases, they work just fine in any profile. Rules are stored in your message store—they aren't included when you use Import and Export. For that reason, Import and Export is not recommended. You can export your rules for safekeeping: Select Tools, Rules and Alerts and choose Options, and then Export Rules or Import Rules. Rules are tied to the name and location of your PST, and you might need to repair the rules by selecting a new folder for each rule that moves or copies .. .Train your doubt unemployed single mother can’t become a successful author, people who act upon their doubt have changed the world So if you are feeling overwhelmed by doubt, ask yourself... by doubt, ask yourself if it might not be that you are on the verge of some sort of breakthrough yourself 2/2
