Remove Filter  | I'm revisiting a topic previously discussed in this thread: [url="http://www.daniweb.com/techtalkforums/thread23030.html"]http://www.daniweb.com/techtalkforums/thread23030.html[/url] The basic issue is this: when using a [b]StreamReader[/b], and [b]ReadLine[/b], to process a text file, you cannot determine where you are "at" within a file. This is because [b]StreamReader[/b] doesn't actually read from a FILE, it reads from a … |

| | I'm working with C#, and Adobe Acrobat 6.0 Professional. Acrobat exposes a COM Automation server with a few top-level objects. It's easy enough to create instances of those objects, by getting their Type via the .GetTypeFromProgID() method, and then using Activator.CreateInstance(). [code] // Create an Acrobat Application object Type AcrobatAppType; … |
| | First, sorry for posting this here, but I couldn't find a VBScript forum on Daniweb (which I find surprising). I'm working with binary data in several different projects. Below is an example of code that works to retrieve a static map image (PNG) from Google: [CODE]strFileURL = "http://maps.google.com/maps/api/staticmap?markers=2200+S+Western+Ave+Lisle+IL&zoom=14&size=400x400&sensor=false" Set objXMLHTTP … |

I store Update or Delete in the .CommandName property. I store the identity value (the primary key) of the database record … |
| | For one of my customers, I have to develop applications that communicate with each other via fixed-width files. In other words, they have developed a file format that is "generic" to a lot of operations. If I write a new utility, it is expected that the utility will be able …  |
| | Recently, I noticed some strangeness on my home wireless network. Sometimes the speed would be slower than normal, I couldn't print to my printer, and some of my more advanced router settings (for port forwarding, firewall, etc.) would seem to be "lost". As it turns out, my laptop was attaching …  |
| | I have a love-hate relationship with Palm. First, the love: for starters, Palm-based PDAs do everything I want a PDA to do. Just give me the basics, such as a nice contact list, memo/notepad, a to-do list, etc. Palm has always done that, and that's all it really needed to …  |
| | Last August, Business 2.0 magazine published an article that speculated Google was considering building a U.S. broadband network capable of targeting specific advertising to users, based on the location of their WiFi. The so-called "Google.net"" or "Google WiFi" caused much speculation, however, the company remained close-lipped. Tuesday, Google finally made … |
| | Web Developer. Webmaster. Web Designer. What do these terms mean? Which one are you?

| | I'll admit it right up front: I'm an old guy, and this is a "kids these days" rant. Pull up your pants, comb your hair, and for Pete's sake, learn to type! I'm referring to what is variously known as "txt lingo", "txt msg spk", or my own term: laziness. … |
| | Hi. I'm having some difficulty with a project that involves working with very large binary files. These are PCL files, where the decimal character "12" represents a Form Feed, but only if it's not embedded within a string of binary data. In other words, I'm looking for decimal "12", then … |
| | Hello, this is not a Web Development question, but this is the only XML forum on Daniweb. I need to copy a specific number of nodes in an XSLT transform. For example, I need to copy the first 5 <student> nodes, with all child nodes and attribute nodes, even though … |

| | I'm struggling with XSLT. I need to copy an entire xml file to a new xml file. The input and output should be identical except for the addition of some extra tags around certain elements.

| | As usual, the examples I find for this either don't work, or don't apply. I want to store, essentially, a text file, within my app.config file, and access it programmatically. Here's a simplified version: [code] <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="PostScript" [COLOR=Red]type=""[/COLOR] /> </configSections> <appSettings> <!-- User application … |
| | Does anyone have a good example of how to use this method? All of the MSDN examples I could find are useless because: [LIST=1] [*]they show a hard-coded size for the byte array [*]they show writing the output to the Console[/LIST] Ridiculous. I have a file that contains some binary …  |

| | Has ASP.NET 2.0 introduced a simplified data control for displaying parent/child data? Imagine a HelpDesk application, where you want to display all the "open tickets".

| | How would I go about making this entire class Serializable? What code would I add to a second constructor that would restore state/values from the XML file (de-serialize)? [code] using System; using System.Collections.Generic; using System.Text; namespace tgreer { public class indexer { private Dictionary<string, Int32> _documents; private Dictionary<string, Int32> _pages; … |
| | I run an industry-specific, highly-targeted forum. I'm using a standard ad-rotator, where I can track/charge for clicks, impressions, or duration. I think I could charge a bit more that average because the site is so specific to an industry, nearly every member would be a qualified prospect. That said, what … |
| | Doesn't C# support EBCDIC encoding? I'm working on a project that involves parsing Xerox Metacode print streams, encoded as variable-byte EBCDIC records. The print stream data itself is in ASCII, but the record headers and control records are in EBCDIC. I read the records in as byte arrays. I know … |
| | Consider the following code snippet: [code]counter = 0; workOperations = new String [OPERATIONS.Count,2]; foreach ( System.Array o in OPERATIONS) { workOperations[counter,0] = (string) o.GetValue(0,0); workOperations[counter,1] = (string) o.GetValue(0,1); counter++; } ps.Operations = workOperations;[/code] There has got to be a better way to do this! The issue is, the [b]ps.Operations[/b] property … |
| | With all the recent news and attention to the latest Google products, I've found myself becoming increasingly paranoid about Google. Have things started to take a creepy turn, or is it just my imagination? For example, the Google Library Project, and the Google Print Project. Who gave Google the right … |
| | I run a couple of low-volume, niche-specific sites. I run ads on them, from that big search engine company. I was recently told that my account was terminated for "invalid clicks", with no further details. I can only speculate that someone overenthusiastically clicked many, many ads. Searching the web a …  |
| | This is for a site concept I'm working on. Can multiple AdSense publishers exist on a single page? For example, imagine a site that I run, on which YOU contribute. If you contribute an article, I want the article page to have MY Google Ads at the top, and YOUR … |
| | I just got a new laptop. It has dual Intel Pentium P4 2.8G processors installed. I'm running Windows XP Professional. My question is, does XP really use two processors? How? At what point are both processors being used? Under heavy load? At all times? Is there a way to assign … |
| | I've often wanted a true blog/forum hybrid. I know exactly what I want, until I try to describe it! I think I basically want a forum, but one that doesn't look so rigidly structured as a forum. Also, I want something a bit more user-oriented, than topic-oriented. I'd like a …  |
| | Let's see if I can completely strike-out, with a third unanswered post: I would like to know how to store binary data in the app.config file for a C# application. These are basically text strings, but they do include one or two "binary" characters, such as decimal 12. I need … |
| | Since nobody answered the thread on Binary File IO, I took a different approach. Now I'm having another problem. As I process a very large (>2GB) binary file, I store the byte position at certain points. Then, I reposition the file as needed. I store the byte positions in a … |
