  • Outlook 2007 unable to connect to exchange server

    - by mattwarren
    I came into the office a week ago and outlook has refused to connect ever since, it just says "Disconnected" in the bottom right-hand corner. I've tried restarting it, rebooting Windows etc. I'm the only one if our office who is having this problem, so it's not a general problem with the server. Things I've tried Pinging the server via IP address and host name, both work fine Connecting via OWA, this works using the same machine name Connecting to Exchange via HTTP ("Outlook Anywhere") doesn't work None of the suggestions in this question helped, http://serverfault.com/questions/21755/can-ping-exchange-server-cant-connect-outlook-to-it Disabling Windows firewall on my laptop also has no effect. There are no items in the event viewer that indicate that anything it up. Also no permissions have changed on the server since when it worked. What else can I do to diagnose this, any suggestions?

  • grep + sed for find & replace fun!

    - by Jim Greenleaf
    I have a dev copy of a website set up that has quite a few hardcoded references to its live counterpart. I would like to replace all occurrences of "www." with "dev." in all files. I think I can use a combination of grep + sed, but I'm not sure how.

  • determining if .htaccess is working

    - by Toc
    Following some guide on the web, I have created the following .htaccess for my WordPress installation: # protect the htaccess file <files .htaccess> order allow,deny deny from all </files> # protect wpconfig.php <files wp-config.php> order allow,deny deny from all </files> plus chmod wp-config.php 600 and .htaccess 644. Which is the simplest way I can test if it is working properly? In case, I can create some other files to verify the work. I only want to be sure.

  • How to remove password protection from compressed files

    - by Mehper C. Palavuzlar
    This has always been a problem for me for a long time. Let's see if any SuperUser can solve this: I have a directory in which there are lots of password protected .RAR files of which I know the passwords. I want to remove the password protection from all of them without extracting the contents. Since each file is larger than 1 GB, decompressing & then recompressing without password encryption is not a good option for me. How can I easily do that? I'm using WinRAR 3.80 on Win7. Any other 3rd party tools are welcomed.

  • Auto-arrange <li> elements into equal columns

    - by 47
    I have several values I'm rendering as elements on my template and I want to further this by having them arranged into equal (or near-equal columns) automatically in the template. How can I achieve this? So far I'm rendering all the values as <ul> {% for feature in features %} <li>{{ feature }}</li> {% endfor %} </ul>

  • teaching my self Z/OS assembler?

    - by Jared
    'I've interned at a company that does a lot of mainframe work. Most of my mainframe experience has been using Java and Unix System Services. I've had some experience with the ISPF interface and C but none with assembler. I’m graduating shortly and will be taking an independent study my last semester. I’d like to stick with the mainframe and was wondering what resources could teach me mainframe assembler? Note I don’t have experience writing assembler for any platform but do understand binary, hex, and have a theoretical understanding of registers.

    - by vaibhav
    I am working on a GridView in Asp.Net. When initially a the Page Loads, my gridview look like: When a user clicks, to edit a row, I am using edit templates to show 'Domain' in a DropDownList. But problem is , when the DropDownlist gets load with data, it lost the current value of the 'Domain'. i.e If I want to edit 4th Row, its domain which is currently set to 'Computers' is getting changed to 'MBA' which is ofcourse the first element return by the DataSource. I want to display the current value ('computers') as the selected value in DropDownList. But I am unable to get the value of Domain, which is being edited.

  • Get the closest number

    - by user183089
    Hi, i am implementing a little Black Jack game in C# and i have the following problem calculating the player's hand value. the problem is Ace may have value of 1 or 11 so if the players has three cards and one Ace if the sum of the cards is <= 10 Ace will have value of 11(Sorry for who doesn't know the scope of the game is to reach 21 with the sum of the cards) Other way value of 1 Up to here is easy Now lets assume i do not know how many Aces the player has got and the game is implemented giving the possibility to the dealer to use more than one deck of cards. the user may have in one hand even 5,6,7,8 ... aces. What is the best way(possibly using Linq) to evaluate all the aces the player has got to get the closest combination to 21 (in addition tot he other cards)? I hope i have been clear thanks for your help.

  • Need help with SQL table structure transformation

    - by Arnis L.
    I need to perform update/insert simultaneously changing structure of incoming data. Think about Shops that have defined work time for each day of the week. Hopefully, this might explain better what I'm trying to achieve: worktimeOrigin table: columns: shop_id day val data: 123 | "monday" | "9:00 AM - 18:00" 123 | "tuesday" | "9:00 AM - 18:00" 123 | "wednesday" | "9:00 AM - 18:00" shop table: columns: id worktimeDestination.id worktimeDestination table: columns: id monday tuesday wednesday My aim: I would like to insert data from worktimeOrigin table into worktimeDestination and specify appropriate worktimeDestination for shop. shop table data: 123 1 (updated) worktimeDestination table data: 1 | "9:00 AM - 18:00" | "9:00 AM - 18:00" | "9:00 AM - 18:00" (inserted) Any ideas how to do that?

  • Persistence of texture parameters

    - by fen
    I use glBindTexture() to bind a previously created texture. After the glBindTexture() call I use glTexParameteri() to set MIN and MAG filter. No problem so far. Are those parameters I set using glTexParameteri() bound to the texture itself or are they lost if I bind another texture. Do i have to set them again? glGenTexture(1, &tex1); glGenTexture(1, &tex2); /* bind tex1 and set params */ glBindtexture(GL_TEXTURE_RECTANGLE_ARB, tex1); glTexImage2D(GL_TEXTURE_RECTANGLE_ARB, ...); glTexParameteri(GL_TEXTURE_RECTANGLE_ARB, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_RECTANGLE_ARB, GL_TEXTURE_MAG_FILTER, GL_LINEAR); /* do something */ /* bind tex2 and set params */ glBindtexture(GL_TEXTURE_RECTANGLE_ARB, tex2); glTexImage2D(GL_TEXTURE_RECTANGLE_ARB, ...); glTexParameteri(GL_TEXTURE_RECTANGLE_ARB, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_RECTANGLE_ARB, GL_TEXTURE_MAG_FILTER, GL_LINEAR); /* do something */ /* bind tex1 again */ glBindtexture(GL_TEXTURE_RECTANGLE_ARB, tex1); /* do i have to set the parameters from above again or are they stored with tex1? */

  • Do I need to use decimal places when using floats? Is the "f" suffix necessary?

    - by Paulo Fierro
    I've seen several examples in books and around the web where they sometimes use decimal places when declaring float values even if they are whole numbers, and sometimes using an "f" suffix. Is this necessary? For example: [UIColor colorWithRed:0.8 green:0.914 blue:0.9 alpha:1.00]; How is this different from: [UIColor colorWithRed:0.8f green:0.914f blue:0.9f alpha:1.00f]; Does the trailing "f" mean anything special? Getting rid of the trailing zeros for the alpha value works too, so it becomes: [UIColor colorWithRed:0.8 green:0.914 blue:0.9 alpha:1]; So are the decimal zeros just there to remind myself and others that the value is a float? Just one of those things that has puzzled me so any clarification is welcome :)

  • What does the JS function 'postMessage()' do when called on an html object tag?

    - by Stephano
    I was recently searching for a way to call the print function on a PDF I was displaying in adobe air. I solved this problem with a little help from this fellow, and by calling postMessage on my PDF like so: //this is the HTML I use to view my PDF <object id="PDFObj" data="test.pdf" type="application/pdf"/> ... //this actionscript lives in my air app var pdfObj:Object = htmlLoader.window.document.getElementById("PDFObj"); pdfObj.postMessage([message]); I've tried this in JavaScript as well, just to be sure it wasn't adobe sneaking in and helping me out... var obj = document.getElementById("PDFObj"); obj.postMessage([message]); Works well in JavaScript and in ActionScript. I looked up what the MDC had to say about postMessage, but all I found was window.postMessage. Now, the code works like a charm, and postMessage magically sends my message to my PDF's embedded JavaScript. However, I'm still not sure how I'm doing this. I found adobe talking about this method, but not really explaining it: HTML-PDF communication basics JavaScript in an HTML page can send a message to JavaScript in PDF content by calling the postMessage() method of the DOM object representing the PDF content. Any ideas how this is accomplished?

    Possible Duplicates: Same keyword for two purposes in java? Same keyword for two purposes in java? As we use "default" keyword as a access specifier, and it can be used in switch statements as well with complete different purpose, So i was curious that is there any other keywords in java which can be used in more then one purposes

  • What do I do about a Java program that spawned two instaces of itself?

    - by user288915
    I have a java JAR file that is triggered by a SQL server job. It's been running successfully for months. The process pulls in a structured flat file to a staging database then pushes that data into an XML file. However yesterday the process was triggered twice at the same time. I can tell from a log file that gets created, it looks like the process ran twice simultaneously. This caused a lot of issues and the XML file that it kicked out was malformed and contained duplicate nodes etc. My question is, is this a known issue with Java JVM's spawning multiple instances of itself? Or should I be looking at sql server as the culprit? I'm looking into 'socket locking' or file locking to prevent multiple instances in the future. This is the first instance of this issue that I've ever heard of. More info: The job is scheduled to run every minute. The job triggers a .bat file that contains the java.exe - jar filename.jar The java program runs, scans a directory for a file and then executes a loop to process if the file if it finds one. After it processes the file it runs another loop that kicks out XML messages. I can provide code samples if that would help. Thank you, Kevin

  • Auto generate varchar Ticket number via DB...

    - by Rusty
    Hello, I'm looking for suggestion on how to get the DB to auto generate Ticket numbers (preferably via the SQL DB) for a varchar column. I have the following tables in the DB: Activities & Cases and would prefer the format to be "Act000001" or "Cse000001". This would be something similar to the identity column property. Any suggestion would be highly appreciated. Thanks. Rusty

  • Clear tableView cell cache (or remove an entry)

    - by ManniAT
    Hi, I have the same question problem as described here http://stackoverflow.com/questions/2286669/iphone-how-to-purge-a-cached-uitableviewcell But my problem can't be solved with "resetting content". To be precise - I use a custom cell (own class). While running the application it is possible that I have to use a different "cell type". It's the same class - but it has (a lot of) differnt attributes. Of course I could always reset all the things at "PrepareForReuse" but that's not a good idea I guess (there are a lot things to reset). My idea - I do all these things in the constructor of the cell. And all the rows will use this "type of cell" later. When the (seldom) situation comes that I have to change the look of all rows I create a new instance of this kind of cell with different settings. And now I want to replace the queued cell with this new one. I tried it with simply calling the constructor with the same cellidentifier (in the hope it will replace the existing one) but that doesn't work. I also didn't find a "ClearReusableCells" or something like this. Is there a way to clear the cache - or to remove / replace a specific item? Manfred

  • Managing highly repetitive code and documentation in Java

    - by polygenelubricants
    Highly repetitive code is generally a bad thing, and there are design patterns that can help minimize this. However, sometimes it's simply inevitable due to the constraints of the language itself. Take the following example from java.util.Arrays: /** * Assigns the specified long value to each element of the specified * range of the specified array of longs. The range to be filled * extends from index <tt>fromIndex</tt>, inclusive, to index * <tt>toIndex</tt>, exclusive. (If <tt>fromIndex==toIndex</tt>, the * range to be filled is empty.) * * @param a the array to be filled * @param fromIndex the index of the first element (inclusive) to be * filled with the specified value * @param toIndex the index of the last element (exclusive) to be * filled with the specified value * @param val the value to be stored in all elements of the array * @throws IllegalArgumentException if <tt>fromIndex &gt; toIndex</tt> * @throws ArrayIndexOutOfBoundsException if <tt>fromIndex &lt; 0</tt> or * <tt>toIndex &gt; a.length</tt> */ public static void fill(long[] a, int fromIndex, int toIndex, long val) { rangeCheck(a.length, fromIndex, toIndex); for (int i=fromIndex; i<toIndex; i++) a[i] = val; } The above snippet appears in the source code 8 times, with very little variation in the documentation/method signature but exactly the same method body, one for each of the root array types int[], short[], char[], byte[], boolean[], double[], float[], and Object[]. I believe that unless one resorts to reflection (which is an entirely different subject in itself), this repetition is inevitable. I understand that as a utility class, such high concentration of repetitive Java code is highly atypical, but even with the best practice, repetition does happen! Refactoring doesn't always work because it's not always possible (the obvious case is when the repetition is in the documentation). Obviously maintaining this source code is a nightmare. A slight typo in the documentation, or a minor bug in the implementation, is multiplied by however many repetitions was made. In fact, the best example happens to involve this exact class: Google Research Blog - Extra, Extra - Read All About It: Nearly All Binary Searches and Mergesorts are Broken (by Joshua Bloch, Software Engineer) The bug is a surprisingly subtle one, occurring in what many thought to be just a simple and straightforward algorithm. // int mid =(low + high) / 2; // the bug int mid = (low + high) >>> 1; // the fix The above line appears 11 times in the source code! So my questions are: How are these kinds of repetitive Java code/documentation handled in practice? How are they developed, maintained, and tested? Do you start with "the original", and make it as mature as possible, and then copy and paste as necessary and hope you didn't make a mistake? And if you did make a mistake in the original, then just fix it everywhere, unless you're comfortable with deleting the copies and repeating the whole replication process? And you apply this same process for the testing code as well? Would Java benefit from some sort of limited-use source code preprocessing for this kind of thing? Perhaps Sun has their own preprocessor to help write, maintain, document and test these kind of repetitive library code? A comment requested another example, so I pulled this one from Google Collections: com.google.common.base.Predicates lines 276-310 (AndPredicate) vs lines 312-346 (OrPredicate). The source for these two classes are identical, except for: AndPredicate vs OrPredicate (each appears 5 times in its class) "And(" vs Or(" (in the respective toString() methods) #and vs #or (in the @see Javadoc comments) true vs false (in apply; ! can be rewritten out of the expression) -1 /* all bits on */ vs 0 /* all bits off */ in hashCode() &= vs |= in hashCode()
