Remove Filter  | This is an extremely basic question, but I haven't found an answer yet. I recently purchased a brand-new computer with Windows 10 and at the moment am using the Microsoft Edge browser that came with it. I would like to open some offline (HTML) pages, but the Control-O feature to …  |
| | I am updating a C++ program, part of which copies arrays of doubles by iterating through each array (copies elements of array wa2 into array X): for (j = 0; j < N; ++j) { X[j] = wa2[j]; } // End for j I would like to use the built-in …  |
| | Some of my connections on LinkedIn have been sending me requests to also connect with them on ReferHire and Dock (if you're on LinkedIn, you probably know what I am talking about.) So far, I have resisted. My first impression is something like, "Great. More social media networks. Isn't there … |
| | I haven't used Twitter but keep seeing it mentioned in the social media community. And a couple weeks ago, I attended a short course in which Twitter was mentioned as a tool for job hunting (in addition to LinkedIn). So now I am considering creating an account and trying it …  |
| | I have translated many numerical math programs from FORTRAN into C++ and JavaScript. The original FORTRAN source code listings are posted on the NETLIB site and have been in the public domain for 20, 30, years. The C++ and JavaScript translations that I write are hand-coded, line-by-line, and repeatedly tested …  |
| | I have been writing plain old vanilla JavaScript pages for a while, for numerical math problems. Usually, I create one page for a specific problem. For example, one page to solve a system of 3 Equations in 3 Unknowns, one page to solve a system of 4 Equations in 4 … |
| | I am trying to translate an old FORTRAN program to C++ and appear to have hit a brick wall. I do not understand how one of the variables returned by a sub-routine can ever take a particular value. I am not a FORTRAN master; maybe somebody here is more familiar …  |
| | I finally registered for a Twitter account and just added it to my Daniweb Profile. At first, I tried to add the full URL, but an error message popped up stating only letters, numbers, and underscores were allowed. So I changed the field entry to my username only (not even …  |
| | I am considering upgrading a computer from Windows 7 Home Premium to Windows 10. However, before I start the process, I have a couple questions hopefully users here can answer: 1) Does the upgrade require user registration info? The computer came with Windows pre-installed, years ago, and I really don't … |
| | One of my websites recently had problems with the PHP news parser. For many years, it worked fine. However, a while back it started acting up. See the attached image of a screenshot. And since the PHP parser was the first block of code on the page, since it didn't … |
| | I am just getting my feet wet with Git and am looking for tutorials for beginners. I am reading through the book, "Version Control with Git" by Jon Loeliger and Matthew McCullough, but am not finding it suitable for a Git virgin. It is written as if the reader is … |
| | I am trying to understand some old FORTRAN code and have reached a point that puzzles me. In the main program, a 1-D work array has been defined. i.e. - REAL WORKA(30) Later on, portions of this work array are passed into a few sub-routines: e.g. - CALL SNAME1 (10, …  |
| | I am working with dynamic arrays which have been created using **<vector>**. For convenience, I have created a typedef : typedef vector<double> C1DArray; In the main program, several variables are created using this definition which, at the moment, means working with arrays of size 30. main() { . . . …  |
| | I am trying to convert some old FORTRAN code to C++. I am about three sub-routines deep into the code and one of the sub-routines includes the following line (twice): CDIR$ IVDEP This is the first time I have come across this command, or directive, or whatever it is. What … |
| | For the past while, I have gotten comfortable doing things a particular way when it comes to inputting data: i) create text file whose first entry is N, an integer indicating the number of data entries following, and the actual data entries. For example, for 101 data values, the text … |
| | I (finally) signed up for a Twitter account and am spending some time to customize my Profile. A few free services have been mentioned that provide this functionality: add URLs, change pattern, add LinkedIn URL, etc. -- basically, a template that prompts users to input their info and then outputs … |
| | Attached are two images that I took on a Windows 7 machine. They are portions of a document that was just opened in Adobe Reader X (Version 10.1.9). One image is of a yellow ribbon across the top of the document, warning about certain data security risks. The other image … |
| | I have been spending a lot of time on LinkedIn lately and one feature I find annoying is the infinite scroll. I simply want to learn more about some companies: their size, earnings, number of employees, mailing address, etc. So I go to the company page on LinkedIn and quickly … |
| | I am trying to use Visual Studio's debugging features more effectively; I certainly do not know all its ins and outs. At the moment, I would like to quickly see the values of an array. See the attached screenshot of the Watch Window. The variable **k** is a global array … |
| | Yesterday (October 25) I spent a few hours working on a Word document. When printed out, it is six pages long. This morning (October 26) when I opened up the document to resume work on it, all my latest work was gone. The document property indicates it was last modified … |
| | It has been a while since I tweaked my Profile, and I just spent a few minutes reviewing it. There are fields in our Daniweb Profiles for our Facebook and LinkedIn URLs (among others). I hesitate to share this information because I'd probably end up with many "friends" from India, … |
| | Facebook sometimes suggests people with whom I can connect. Some of them are old contacts from high school. However, the odd time I wonder if I have already sent them a friend request, which they have ignored. My question: Is there a way to tell if I have previously sent …  |
| | I would like to use Linux at home but do not want it to mess up anything on my home PC (Windows 7). Ideally, I would like to run it from a USB drive, as independent from the PC as possible. This is totally new territory for me, so I …  |
| | Any time I have included an alert in a Javascript program, I have simply called it as "alert", for example, alert("The value of the variable is presently " + varValue + "."); However, I also see code that calls it as window.alert. For example, window.alert("The value of the variable is …  |
| | I have worked on a few blogs for several years and have treated them as a creative outlet. Haven't been concerned about getting followers or traffic. Presently, the "Blogroll" section of my blog is empty. However, I am now considering adding several URLs to this section. I don't plan to … |
| | Hi, folks. I would like to start posting a few C++ code snippets and thought I would start with something well-known and simple: a Quadratic Equation Solver. I am trying to be as thorough as possible, so am also considering the possibility that a non-quadratic equation might be fed into … |
| | I think I just messed up my signature. It was the same for several years: it had the anchor text I wanted and hot-linked to my website. It was pretty much just how I wanted it. However, I just made a small punctuation change and now my hot-linked anchor text … |
| | Hi, folks. I have written some pretty complicated programs in Javascript (in terms of the code itself), but I haven’t experimented much with the nuts-and-bolts of Javascript. In particular, I have written all my programs as single blocks of code. For example, I have written several programs to solve for … |
| | The latest NASA rover to be sent to Mars, Curiosity, successfuly landed on Mars late yesterday evening. I think this is wonderful. Anybody else in Daniweb following the progress of this mission?  |
| | I am putting together a wish list for a new computer. I would like it to be dual-boot: Windows 7 and Linux (probably Ubuntu because I am not proficient with Linux). Any advice, tips, or suggestions for factors I should take into consideration when selecting a new computer? Does type … |
| | Digg and Delicious used to be two of my favorite sites; I would visit them daily. However, Delicious is making some significant changes lately. I found some of my favorite links from the Delicious front page; however, presently the Delicious front page has a couple images, which don't appear to …  |
| | Hi, I am wondering if there is a way to include subscripts or superscripts in Daniweb? I just answered a question about polynomials and it would have been nice to have more math symbols available to discuss math-related topics when they come up. For example, instead of writing a polynomial …  |
| | I had posted a photo of myself (jpg) on a Wiki (uses MediaWiki) and updated it recently. Now I am wondering how to delete the old photo. The link *to* the image has been deleted, but the image itself is still there, taking up space on the server. I didn't …  |
| | I have recently gotten more involved in the logistics side of my employer’s activities and we use SAP for a large part of our CMS work (specifically, SAP by Design). We have hundreds of Sales Orders (SOs) in the system and they are spread out to 2016. I am now … |
| | Hi all. I am just beginning to play with Linux, so I have some very noob-ish questions. I am using the Cygwin console on a Windows 7 computer, connecting to a server running a Gentoo kernel. At the moment, I am exploring some of the *real* basic commands: cp, pwd, … |
| | I haven't had time to explore thoroughly, but I don't see an option to NOT have my signature included with a post. Even though I have a signature created in my Profile, I previously would uncheck the option to have it displayed with most posts. Now I don't see that … |
| | One feature I missed with the previous version of Daniweb was the ability to do an Advanced Search. In other forums using vBulletin, I was able to search for posts by, say, username, in a particular forum, in the past month, etc. The present incarnation of Daniweb doesn't seem to … |
| | I recently started a new job and have been asked to install and configure an IRC client so that everybody in the department can stay in touch--even when some people are working from home. This is totally new to me. Apparently MSN Messenger is only good for one-to-one communication, but … |
| | I had an old version of Mathcad (version 7) running on an old computer (running Windows 2000). That computer recently died, but I have several .mcd files saved. I doubt there is an upgrade path for me; my version was too old. And 95% of the time, I used it …  |
| | I am doing some pre- Spring Cleaning and want to get out of my home a bunch of old cassettes. They still work, and I bought them properly (since piracy wasn’t as popular several years ago), so I hate to just throw them in the garbage. But I’d like the …  |
| | Hi, everybody. I am reviewing some old code and two questions came to mind. 1) Is it better to use “[B]\n[/B]” or [B]endl[/B]? [INDENT]"[B]\n[/B]" seems to be working just fine, but most code samples I see in books nowadays use [B]endl[/B]. What is the difference?[/INDENT] 2) For multi-line output statements, …  |
| | I recently changed hosts for one of my web sites. Signed up for a three-year term and all the bells and whistles. When I logged into cPanel, the account came with five e-coupons for advertising: Google AdWords, Facebook, Bing/Yahoo!, Miva, and Bidvertiser. I am definitely not going to turn down … |
| | Hi, folks. I recently started posting photos on Flickr and a pretty simple question just came to mind. I didn't see it mentioned in the FAQs, but maybe somebody in these forums is more familiar with the service than I am. How long do photos remain accessible through my account? …  |
| | Hi, folks. As you may have gathered from a previous post, I know next to nothing about PHP, so I have a very basic question: How do I force an exit from PHP? I have gone through a few books and come across the "die" and "exit" commands; however, they … |
| | I am planning to change the web host of one of my web sites, and the site has a webmail service (similar to Hotmail, etc.). I recall that when I first set it up, I had to edit the MX record in the DNS file. Before I change the web …  |
| | I have almost no experience with PHP so I need some help with a small code block. My website used to be hosted by a company within my own time zone, so I used the following code to output the date and time on my web page: [CODE] <?php print … |
| | One of my computers recently crashed. Fortunately, the .pst file was saved so not all is lost. However, I am considering [I]not[/I] installing Microsoft Outlook on the new computer. It seemed to take over too much of my system. A couple considerations: (1) If I install Outlook Express instead of … |
| | I am quite irritated with Yahoo's new policy of requiring new users of their Delicious service to sign up with a Yahoo! ID. I do not want more email addresses to worry about, etc. I just want to bookmark. So now I am wondering, among all of Google's offerings, do … |
| | Hi, folks. Hopefully, some of the "geeks" in this lounge can help me with a topic from American History. I think it was in Grade 10 (which was quite a few years ago) that I learned a little about early American history. Some years after the original thirteen colonies were … |
| | (Yes, I am behind the times, but bear with me.) I finally picked up an Ipod and have started loading it with music. However, I have one question: Is there a way to delete music from Itunes without having it deleted from the iPod the next time it synchs? It … |
The End.
