• Disable passwd history feature with remember=0

  - by user1915177

  PAM version - pam-0.79 Is setting 0 allowed on "remember" option in /etc/pam.d/common-passwd file of pam.d module to disable passwd history feature? With "remember=0" in /etc/pam.d/common-passwd file, I am observing a memfault when running the passwd command as a USER. When browsed the source, the function in _set_ctrl in support.c file of pam_unix module handles wrong values of remember, but currently its not robust enough to handle 0, which is a wrong value. So the valid and only option to disable history feature, is to not include the "remember" option in /etc/pam.d/common-passwd file and not to set-up /etc/security/opasswd file? Could see in the following link mention of setting "remember" to 0 has no effect to remember value in "/etc/security/opasswd" file. =https://lists.fedorahosted.org/pipermail/linux-pam-commits/2011-June/000060.html

• Writing Macros to find a specific cell and paste the value from a control cell into it

  - by G-Edinburgh

  I am having some issues writing a Macro to do the following. I have a very long list of rooms with two columns one containing the room number i.e. B-CL102 and the other containing a varying integer.I am looking to create a new column that will contain another different integer for each of the rooms. Is there any way to write a Macro so that I can use two control cells at the top of the sheet, type the room number into one and the integer matching that room into another, then run the Macro and it will automatically populate the correct cell. Then I can change the two values in the control cells and run the Macro again and so on. Thanks for your help, I have a very minimal amount of experience with Macros essentially just the basics. Thanks G

• Smoothing rotation

  - by Lewis

  I've spent the last three days trying to work out how to rotate a sprite smoothly depending on the velocity.x value of the sprite. I'm using this: float Proportion = 9.5; float maxDiff = 200; float rotation = fmaxf(fminf(playerVelocity.x * Proportion, maxDiff), -maxDiff); player.rotation = rotation; The behaviour is what I required but if the velocity changes rapidly then it will look like the sprite will jump to face left or jump to face right. I'll go into the behaviour in a little more detail: 0 velocity = sprite faces forwards negative velocity = sprite faces left depending on value. positive velocity = sprite faces right (higher velocity the more it faces right) same as above. I've read about using interpolation rather than an absolute angle to rotate it to but I don't know how to implement that. I have a physics engine available. There is one other way to get around this: to use += on the rotation angle. The thing is that I would then have to change the equation to produce positive and negative values then to make sure the sprite faces 0 once it reaches 0 velocity again. If I add that in now, it keeps the previous angle even after the velocity has dropped / is dropping. Any ideas/code snippets would be greatly appreciated.

• How do I populate multiple records of data into a PDF form like a mail-merge?

  - by user38801

  I have Acrobat Pro, and I have a PDF with a form on it. Assuming the fields in the form correspond to a data source (like rows in an RDBMS table or xml file), I want to then print multiple copies of the PDF file, with each copy having the values of a different row in the data source. It is preferable to directly interface with an actual database, rather than having to save an XML file every time I do this. If this involves programming that's cool too, I only posted here because the question didn't seem appropriate for StackOverflow. Thanks!

• Need help understanding Mocks and Stubs

  - by Theomax

  I'm new to use mocking frameworks and I have a few questions on the things that I am not clear on. I'm using Rhinomocks to generate mock objects in my unit tests. I understand that mocks can be created to verify interactions between methods and they record the interactions etc and stubs allow you to setup data and entities required by the test but you do not verify expectations on stubs. Looking at the recent unit tests I have created, I appear to be creating mocks literally for the purpose of stubbing and allowing for data to be setup. Is this a correct usage of mocks or is it incorrect if you're not actually calling verify on them? For example: user = MockRepository.GenerateMock<User>(); user.Stub(x => x.Id = Guid.NewGuid()); user.Stub(x => x.Name = "User1"); In the above code I generate a new user mock object, but I use a mock so I can stub the properties of the user because in some cases if the properties do not have a setter and I need to set them it seems the only way is to stub the property values. Is this a correct usage of stubbing and mocking? Also, I am not completely clear on what the difference between the following lines is: user.Stub(x => x.Id).Return(new Guid()); user.Stub(x => x.Id = Guid.NewGuid());

• Matlab: Why is '1' + 1 == 50? [migrated]

  - by phi

  Matlab has weak dynamic typing, which is what causes this weird behaviour. What I do not understand is what exactly happens, as this result really surprises me. Edit: To clarify, what I'm describing is clearly a result of Matlab storing chars in ASCII-format, which was also mentioned in the comments. I'm more interested in the way Matlab handles its variables, and specifically, how and when it assigns a type/tag to the values. Thanks. '1' is a 1-by-1 matrix of chars in matlab and '123' is a 1-by-3 matrix of chars. As expected, 1 returns a 1-by-1 double. Now if I enter '1' + 1 I get 50 as a 1-by-1 double, and if I enter '123' + 1 I get a 1-by-3 double [ 50 51 52 ] Furthermore, if I type 'a' + 1 the result is 98 in a 1-by-1 double. I assume this has to do with how Matlab stores char-variables in ascii form, but how exactly is it handling these? Are the data actually unityped and tagged, or how does it work? Thanks.

• Iozone: sensible settings for a server with lots of RAM

  - by Frank Brenner

  I have just acquired a server with: 2x quadcore Xeons 48G ECC RAM 5x 160GB SSDs on an LSI 9260-8i Before deploying the target platform, I'd like to collect as much benchmark data as possible, testing I/O with hardware RAID in various configurations, ZFS zRAID, as well as I/O performance on vSphere and with KVM virtualization. In order to see real disk I/O performance without cache effects, I tried running Iozone with a maximum file of more than twice the physical RAM as recommended in the documentation, so: iozone -a -g100G However, as one might expect, this takes far too long to be practicable. (I stopped the run after seven hours..) I'd like to reduce the range of record and file sizes to values that might reflect realistic performance for an application server, hopefully getting the run times to under an hour or so. Any ideas? Thanks.

• Nullable types and ?? operator C# [en-US]

  - by ruimachado

  Nullable types vs Non-nullable types   While developing our C# projects its frequent the null comparison operation to avoid null exceptions. This simple operation is mainly coded using the "var x = null" code example inside an if clause. However not all types of variables are nullable, which means that setting a variable to null is not allowed in every cases, it depends on what kind of type are you defining. But what if there was an extension to your non-nullable type that would convert your variable types to nullable? This extension really exists. As I said before in C# you have nullable types which represent all the values of an underlying type, and an additional null value and can be declared easily using "T?", where T is the type of the variable and for example the normal int type cannot be null, so its a non-nullable type, however if you define a "int?" your variable can be null, what you do is convert a non-nullable type to a nullable type. Example: int x=null;     Not allowed     int? x=null;   Allowed     While using nullable types you can check if a variable is null the same way you do it with nullable types:     But what about setting a default value when a certain variable is null?   In this cases the c# .net framework let you set a default value when you try to assign a nullable type to a non-nullable type, using the ?? operator. If you don't use this operator you can still catch the InvalidOperationException which is throw in this cases. For example  without the ?? operator :     Using the ?? operator your code becomes cleaner and more easy to read and you get a bonus, you can set a default value for multiple variables using the ?? in a chain set.     That’s it,   Thanks, Rui Machado rpmachado.wordpress.com

• Algorithm for procedural city generation?

  - by Zove Games

  I am planning on making a (simple) procedural city generator using Java. I need ideas on whan algorithm to use for the layout, and the actual buildings. The city will mostly have skyscrapers, not really much complex stuff. For the layout I already have a simple algorithm implemented: Create a Map with java.awt.Point keys and Integer values. Fill it with all the points in the city's bounds with the value as -1 (unnassigned) Shuffle the map, and assign the 1st 10 of the keys IDs (from 1-10) Loop until all points have IDs: Loop though all points: Assign points next to an assigned point IDs of the point next to them, if 2 or more points border the point, then randomly choose which ID the point will get. You will end up with 10 random regions. Make roads bordering these regions. Fill the inside of each region with a randomly spaced and randomly rotated grid PROBLEM: This is not the fastest way to do it. What algorithm should I use for the layout. And what should I use to make each building's design? I don't even know how I'm going to do that yet (fractals maybe). I just need some ideas, not actual code.

• Changing the Default Install Location of an MSI

  - by PSteele

  A few months ago, I had to tweak an MSI installer.  It was installing into a specific directory (named the same as the application) underneath Program Files.  Since the location of Program Files can change from machine to machine, the MSI has a special token you can use for Program Files (as well as for the application name).  So the current value for “DefaultLocation” of the Application Folder was: [ProgramFilesFolder]\[ProductName] During installation, these tokens would be replaced by the actual location based on the current machine. I needed to change this to a specific folder underneath the users My Documents directory.  I poked around the help file and I could not find where these special tokens (like “[ProgramFilesFolder]”) were defined.  Obviously, there must be some specific set of values that are available and I’m sure My Documents is one of them. I finally found them documented so I’m posting the link here.  Hopefully, it will help someone else out.  Not sure where I found this link… System Folder Properties For me, it was as easy as changing the DefaultLocation to: [PersonalFolder]\MyToolName\Application Technorati Tags: .NET,MSI

• Laptop power button not working

  - by DyP

  I have a (seemingly rather exotic) Dell Latitude XT2 notebook running Lubuntu 12.04, fresh install. Tried to get the power button to work as expected (opening lubuntu-logout, just as I think it was meant to be out-of-the box), but no success: power button does nothing but forced power-off on long press. Here some more information, please ask if something more could help: Power button is recognized as a device: xinput lists Power Button as a slave keyboard at /dev/input/event1, and I can run a tool to listen to that device and invoke some action (successfully). But using .config/openbox/lubuntu-rc.xml to assign some action to XF86ShutDown or XF86PowerOff does nothing. Works well for any key of the keyboard. xinput --test reports a keycode (key press, key release) of 124 when pressing & releasing the power button. xmodmap -pk lists 124 mapped to XF86PowerOff which seems correct to me (btw: is this the same as XF86ShutDown?) When assigning another keysymname to the 124 keycode, e.g. 'w', still nothing happens when pressing the power button (no window seems to receive a 'w'). Works well for any key on the keyboard. The outputs of xev for a press/release of the power button irritate me: MappingNotify event, serial 41, synthetic NO, window 0x0, request MappingKeyboard, first_keycode 8, count 248 FocusOut event, serial 41, synthetic NO, window 0x2a00001, mode NotifyGrab, detail NotifyAncestor FocusIn event, serial 41, synthetic NO, window 0x2a00001, mode NotifyUngrab, detail NotifyAncestor KeymapNotify event, serial 41, synthetic NO, window 0x0, keys: 93 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 (instead of 93, I also get different values) I might have missed something very basic since I'm not very familiar with both openbox/lubuntu and the X input system. Btw.: same goes for three other special buttons on my laptop..

• How to modify partitions after install?

  - by ChocoDeveloper

  I wanted to have Ubuntu with full disk encryption on one big partition, and Windows on a small one. In 12.04, only the Server Edition installer has full disk encryption, so I used that and then installed ubuntu-desktop. When it asked for the size, I reduced it from ~999GB to ~750gb. Now after the install, on both gparted and disk utility I see /dev/sda2 taking ~931GB, and nothing unallocated, so I can't create a partition for windows. I got the size right, because when I right-click inside a folder, then hit 'properties', I see Free space: ~690GB (I don't know why it's not ~750GB, but at least it's not 900). The command df -h shows the same. So what can I do? Normally I would just resize a partition with gparted to create unallocated space, then create the partition. But here I have two problems: gparted does not seem to be showing the correct values, and also it says it does not support LUKS so I'm afraid it will mess things up. Any thoughts?

• Boundary conditions for testing

  - by Loggie

  Ok so in a programming test I was given the following question. Question 1 (1 mark) Spot the potential bug in this section of code: void Class::Update( float dt ) { totalTime += dt; if( totalTime == 3.0f ) { // Do state change m_State++; } } The multiple choice answers for this question were. a) It has a constant floating point number where it should have a named constant variable b) It may not change state with only an equality test c) You don't know what state you are changing to d) The class is named poorly I wrongly answered this with answer C. I eventually received feedback on the answers and the feedback for this question was Correct answer is a. This is about understanding correct boundary conditions for tests. The other answers are arguably valid points, but do not indicate a potential bug in the code. My question here is, what does this have to do with boundary conditions? My understanding of boundary conditions is checking that a value is within a certain range, which isn't the case here. Upon looking over the question, in my opinion, B should be the correct answer when considering the accuracy issues of using floating point values.

• Data Mining Email with Thunderbird

  - by user554629

  Oracle has many formal, searchable locations:  Service Requests, BugIDs, Technical Documents. These contain the results of an investigation for a customer crash situation;  they're created after the intense work of resolution is over, and typically contain the "root cause" of the failure ... but not the methods for identifying that cause. Email is still the standby for interacting with quickly formed groups of specialists, focusing on a particular incident.Customer BI, Network and System specialists;  Oracle Tech Support, Development, Consultants; OEM Database, OS technical support.   It is a chaotic, time-oriented set of configuration, call stacks, changes, techniques to discover and repair the failure. I needed to organize that information into something cohesive to prepare the blog entry on Teradata.  My corporate email client of choice is Thunderbird.   My original (flawed) search technique: R-Click on Inbox in Thunderbird left pane, and choose Search Messages Subject:  [ teradata ] Results: A new window titled "Search Messages"Single pane of selected messagesColumn headings:  Subject  From  Date  LocationNo preview window for messages There are 673 email entries in the result ( too many )  R-click icon just above the vertical scroll bar on the rightCheck [x] Tags Click on the Tags header to sort by "Important" View contents of message by double-clickingOpens in the Thunderbird Main Window in a new Tab Not what I was looking for, close the tab and try again. There has to be a better way.  ( and there is ) I need to be more productive, eliminating duplicate-chained messages, for example.   Even the Tag "Important" that was added during the investigation phase, is "not so much" for my current task. In the "Search Messages" window, click [ Save as Search Folder ] [ teradata ]  Appears as a new folder in my Inbox. Focus on that folder and the results appear with a list of messages like every other folder in the Inbox.Only the results of the search are shown A preview window is now available for each message Sort, Select message, Cursor Down ... navigates quickly through the messages. But wait, there's more ... Click Find ( Ctrl-F) Enter a search term for the message body, like.[ LIBPATH ] The search is "sticky" ... each message you cycle through wil focus ( and highlight) the LIBPATH search term. And still more .... Reset the Tag"Important" message.   Press "1" and the tag is removed Press "4" and a new Tag "ToDo" is applied After applying all of the tags, sort by Tag for a new message order Adjust the search criteria ... R-click on the [ teradata ] search folder, and choose Properties Add additional criteria to narrow the search Some of the information I'm looking for did not contain "teradata" in the subject line. + Body  [ contains ] [ Best Practices ] That's it.  Much more efficient search.   Thank you Thunderbird.

• Quick Fix for GlassFish/MySQL NoPasswordCredential Found

  - by MarkH

  Just the other day, I stood up a GlassFish 3.1.2 server in preparation for a new web app we've developed. Since we're using MySQL as the back-end database, I configured it for MySQL (driver) and created the requisite JDBC resource and supporting connection pool. Pinging the finished pool returned a success, and all was well. Until we fired up the app, that is -- in this case, after a weekend. Funny how things seem to break when you leave them alone for a couple of days. :-) Strangely, the error indicated "No PasswordCredential found". Time to re-check that pool. All the usual properties and values were there (URL, driverClass, serverName, databaseName, portNumber, user, password) and were populated correctly. Yes, the password field, too. And it had pinged successfully. So why the problem? A bit of searching online produced enough relevant material to offer promise. I didn't take notes as I was investigating the cause (note to self), but here were the general steps I took to resolve the issue: First, per some guidance I had found, I tried resetting the password value to nothing (using () for a value). Of course, this didn't fix anything; the database account requires a password. And when I tried to put the value back, GlassFish politely refused. Hmm. I'd seen that some folks created a new pool to replace the "broken" one, and while that did work for them, it seemed to simply side-step the issue. So I deleted the password property - which GlassFish allowed me to do - and restarted the domain. Once I was back in, I re-added the password property and its value, saved it, and pinged...success! But now to the app for the litmus test. The web app worked, and everything and everyone was now happy. Not bad for a Monday.  :-D Hope this helps, Mark

• Outbound Traffic Logging on ASA 5520 possible?

  - by j2k4j

  Taking a look at the ASDM (6.4) for my ASA 5520, I get a nice summary of the traffic status, with items like "interface traffic usage", and "connections per second". This works well, but only shows the data for the last 5-6 minutes or so. Recently, I've been asked whether it's possible to pull up this same type of traffic data for a particular time in the past. (Such as: Find the traffic usage for a 3 minute period from date xx:xx:xx @ time xx:xx:xx) I've noticed that my ASA 5520 is logging the warning, errors, etc that it is processing. But traffic data is not logged (yet) according to my search through the ASA. Is logging the traffic data amounts (as wondered above) actually a possibility? Is there any way to find out the past data for traffic and such values? Thanks!

• Use decorator and factory together to extend objects?

  - by TheClue

  I'm new to OOP and design pattern. I've a simple app that handles the generation of Tables, Columns (that belong to Table), Rows (that belong to Column) and Values (that belong to Rows). Each of these object can have a collection of Property, which is in turn defined as an enum. They are all interfaces: I used factories to get concrete instances of these products, depending on circumnstances. Now I'm facing the problem of extending these classes. Let's say I need another product called "SpecialTable" which in turn has some special properties or new methods like 'getSomethingSpecial' or an extended set of Property. The only way is to extend/specialize all my elements (ie. build a SpecialTableFactory, a SpecialTable interface and a SpecialTableImpl concrete)? What to do if, let's say, I plan to use standard methods like addRow(Column column, String name) that doesn't need to be specialized? I don't like the idea to inherit factories and interfaces, but since SpecialTable has more methods than Table i guess it cannot share the same factory. Am I wrong? Another question: if I need to define product properties at run time (a Table that is upgraded to SpecialTable at runtime), i guess i should use a decorator. Is it possible (and how) to combine both factory and decorator design? Is it better to use a State or Strategy pattern, instead?

• gmetric data submitted doesn't follow dmax value

  - by 580farm

  I have a custom script that is querying a metric port for an application that I'm running and submitting parsed values to ganglia via gmetric. The script runs every minute, so I submit the data to ganglia using the following gmetric options: /usr/sbin/gmetric -g ec2 -s positive -t uint32 -d 600 -n "$NAME" -v $VALUE -x 60 But for some reason there are still gaps in the graphing data: Is there something in my formatting that is preventing the dmax/ttl of the last metric received from being honored? Is there anyone who does custom metric collection that has run into this problem before that can shed some insight or provide some tips as to how to best correct this?

• selecting files in windows-7 explorer just by hovering

  - by bortao

  One of the biggest annoyances for me of Windows 7 vs Windows XP is that you cant select files properly by hovering over them on Windows Explorer (or multi select by holding ctrl). When i hover an item it gets light blue, not selected. Only after a time or after more hovering, it gets selected. I set the delay (MouseHoverTime) to 1. Windows seems to avoid wrong selection by requiring an additional time or space of mouse hovering before actually selecting the item. I tried playing with the values MouseHoverHeight, MouseHoverWidth, MouseSensitivity, MouseThreshold1 and MouseThreshold2 in HKEY_CURRENT_USER\Control Panel\Mouse, but they seem to have no effect over this. (they are currently on (20, 20, 16, 6, 10, respectively). What i want: to immediately select an item whenever the mouse gets over its bounds.

• When decomposing a large function, how can I avoid the complexity from the extra subfunctions?

  - by missingno

  Say I have a large function like the following: function do_lots_of_stuff(){ { //subpart 1 ... } ... { //subpart N ... } } a common pattern is to decompose it into subfunctions function do_lots_of_stuff(){ subpart_1(...) subpart_2(...) ... subpart_N(...) } I usually find that decomposition has two main advantages: The decomposed function becomes much smaller. This can help people read it without getting lost in the details. Parameters have to be explicitly passed to the underlying subfunctions, instead of being implicitly available by just being in scope. This can help readability and modularity in some situations. However, I also find that decomposition has some disadvantages: There are no guarantees that the subfunctions "belong" to do_lots_of_stuff so there is nothing stopping someone from accidentally calling them from a wrong place. A module's complexity grows quadratically with the number of functions we add to it. (There are more possible ways for things to call each other) Therefore: Are there useful convention or coding styles that help me balance the pros and cons of function decomposition or should I just use an editor with code folding and call it a day? EDIT: This problem also applies to functional code (although in a less pressing manner). For example, in a functional setting we would have the subparts be returning values that are combined in the end and the decomposition problem of having lots of subfunctions being able to use each other is still present. We can't always assume that the problem domain will be able to be modeled on just some small simple types with just a few highly orthogonal functions. There will always be complicated algorithms or long lists of business rules that we still want to correctly be able to deal with. function do_lots_of_stuff(){ p1 = subpart_1() p2 = subpart_2() pN = subpart_N() return assembleStuff(p1, p2, ..., pN) }

• JavaScript and the User Experience

  5 sites I commonly vist at home: Google.com Gmail.com Linkedin.com Capella.edu Codeplex.com All of the top 5 sites I visit at home use JavaScript and is applied in various ways for various reasons. Gmail and Google make use of Ajax to retrieve information without the user having to call another page. In addition, all 5 of the websites use JavaScript to enhance a user's experience. Examples of this can be found in content rotation on Capella's main site and the displaying and hiding of specific content sections from within our course room. Codeplex uses Ajax and JavaScript to show dynamic content on its homepage and allow users to page through the data. I think there use of JavaScript is well placed and enhances the viewing experience of the user because it reduces the amount of interaction a user has to perform for them to obtain information they are looking to see. I have used JavaScript in various ways. One of the most memorable ways was to enable an HTML table to be able to have its rows paged and sorted based on the values in each table row.

• Getting Center and Radius of Irregural Object

  - by Moaz ELdeen

  I have drawn an asteroid object manually , and would like to get its center/radius by a specific equation. I think I can get them by calculated and hard-coded values. The code to draw the asteroid: void Asteroid::Draw() { float ratio = app::getWindowWidth()/app::getWindowHeight(); gl::pushMatrices(); gl::translate(m_Pos*ratio); gl::scale(3.5*ratio,3.5*ratio,3.5*ratio); gl::color(ci::Color(1,1,1)); gl::drawLine(Vec2f(-15,0),Vec2f(-10,-5)); gl::drawLine(Vec2f(-10,-5),Vec2f(-5,-5)); gl::drawLine(Vec2f(-5,-5),Vec2f(-5,-8)); gl::drawLine(Vec2f(-5,-8),Vec2f(5,-8)); gl::drawLine(Vec2f(5,-8),Vec2f(5,-5)); gl::drawLine(Vec2f(5,-5),Vec2f(10,-5)); gl::drawLine(Vec2f(10,-5),Vec2f(15,0)); gl::drawLine(Vec2f(15,0),Vec2f(10,5)); gl::drawLine(Vec2f(10,5),Vec2f(-10,5)); gl::drawLine(Vec2f(-10,5),Vec2f(-10,5)); gl::drawLine(Vec2f(-15,0),Vec2f(-10,5)); gl::popMatrices(); } According to the answer I have written that code to calculate the radius, is it correct or not ? cinder::Vec2f Asteroid::getCenter() { return ci::Vec2f(m_Pos.x, m_Pos.y); } double Asteroid::getRadius() { ci::Vec2f _vec = (getCenter()- Vec2f(15,5)); return _vec.length()*0.3f; }

• Intermittent sound

  - by ej159

  The sound on my machine (Medion Akoya S5610) works intermittently. If I reboot enough times I do get sound. This happened before I upgraded, when running Oneiric too. I have fiddled around with alsa-base.conf, putting in different values for model in options snd-hda-intel model=but still the issue persists (although I get the impression that I am more like to have sound on the next reboot if I have edited that file although I can't be sure of this). Adding index=0 does not help the situation either. I have been thinking that this problem could be related some how to the order that driver modules are loaded. The snd-hda-intel module is also used for the sound card (ALC888) in my graphics card. Could it be that these are some how competing? If so, how do I add a preference when they are using the same module? This is the result of lspci -nn | grep Audio (when sound was not working): 00:1b.0 Audio device [0403]: Intel Corporation 82801I (ICH9 Family) HD Audio Controller [8086:293e] (rev 03) 01:00.1 Audio device [0403]: Advanced Micro Devices [AMD] nee ATI RV620 HDMI Audio [Radeon HD 3400 Series] [1002:aa28] I've been wrestling with this problem for ages and ages and have spent days looking for answers on forums but to no avail so I would appreciate any help you can give. Many thanks

• Excel - Disable AutoFormatting on Import

  - by Philip Wales

  How can I stop Microsoft Excel from auto formatting data when imported from a text file? Specifically, I want it to treat all of the values as text. I am auditing insurance data in excel before it is uploaded to the new database. The files come to me as tab delimited text files. When loaded, Excel auto-formats the data causing leading 0's on Zip Codes, Routing Numbers and other codes, to be chopped off. I don't have the patience to reformat all of the columns as text and guess how many zeros need to be replaced. Nor do I want to click through the import wizard an specify that each column is text. Ideally I just want to turn off Excel's Auto-Formatting completely, and just edit every cell as it were plain text. I don't do any formula's or charts, just grid plain text editing.
