  • Any clever way to fix 'string or binary data would be truncated' warning with LINQ

    - by Simon_Weaver
    Is there a clever way to determine which field is causing 'string or binary data would be truncated' with LINQ. I've always ended up doing it manually by stepping through a debugger, but with a batch using 'SubmitChanges' I have to change my code to inserting a single row to find the culprit in a batch of rows. Am I missing something or in this day and age do I really have to still use a brute force method to find the problem. Please dont give me advice on avoiding this error in future (unless its something much cleverer than 'validate your data'). The source data is coming from a different system where I dont have full control anyway - plus I want to be lazy. PS. Does SQL Server 2008 actually tell me the field name. Please tell me it does! I'll upgrade!

  • Linking Access records to Excel files

    - by glinch
    Hi there, I've been trying to create a complete system using MS Access, but i really need to use the functionality of excel spreadsheets. I wish to do the following; when I create a record, i create a directory for that record, and copy an excel spreadsheet to that directory. The spreadsheet will be able to link to the corresponding record. So for example if I have a field 'Name' In the database record, the value of this field will show up on the excel spreadsheet. Is it possible to this?

  • Creating a form dynamically

    - by Nathan
    Hi, I use a search button that creates a form dynamically at the server side and returns it with Jquery syntax. After I fill-up the form and click on submit button, there is another .submit() Jquery function that suppose to be called to validate input before data is sent to the server. But, for some reason, this function is never called, and the data is request is sent. In more details: This is the form that the serach button creates dynamically at the server side and "prints" to html page with Jquery: <form action=... name="stockbuyform" class="stockbuyform" method="post"> <input type=text value="Insert purchasing amount"> <input type="submit" value="Click to purchase"> </form> And here is the .submit() function : $(".stockbuyform").submit(function() { alert("Need to validate purchasing details"); } But whaen I click on purchase button, the .submit() function is never called. Does it mean that I can't use another Jquery call with the answer I got in the first call?

  • NHibernate - is property lazy loading possible?

    - by Ben
    I've got some binary data that I store and was going to separate this out into a separate table so it could be lazy loaded. However, i then came across this post by Ayende (http://ayende.com/Blog/archive/2010/01/27/nhibernate-new-feature-lazy-properties.aspx) which suggests that property lazy loading is now possible. I have added the lazy="true" attribute to my property mapping but the field is still loaded from the database (I am using a simple text field to test). My query: return _session.CreateQuery("from Product") .SetMaxResults(1) .UniqueResult<Product>(); Mapping: <property name="Description" type="string" column="FullDescription" lazy="true"/> Has anyone been able to get this working? Personally I prefer this approach than having to add another table to my database.

  • Weird behaviour of a deserialized class

    - by orloffm
    I've got a huge XML file that's being deserialized by XmlSerializer in an XSD-generated class structure. Everything used to work just fine, but now a weird thing started happening. Sometimes (50% of runs) a field of a certain object of a class that's deep in the class tree just changes to a certain value of the same field of a different object of the same class. It happens when entering some function, when debugger steps from opening "{" to the first line of code. I understand that it's stupid question, but maybe someone have any thoughts?

  • Problem running a Python program, error: Name 's' is not defined.

    - by Sergio Tapia
    Here's my code: #This is a game to guess a random number. import random guessTaken = 0 print("Hello! What's your name kid") myName = input() number = random.randint(1,20) print("Well, " + myName + ", I'm thinking of a number between 1 and 20.") while guessTaken < 6: print("Take a guess.") guess = input() guess = int(guess) guessTaken = guessTaken + 1 if guess < number: print("You guessed a little bit too low.") if guess > number: print("You guessed a little too high.") if guess == number: break if guess == number: guessTaken = str(guessTaken) print("Well done " + myName + "! You guessed the number in " + guessTaken + " guesses!") if guess != number: number = str(number) print("No dice kid. I was thinking of this number: " + number) This is the error I get: Name error: Name 's' is not defined. I think the problem may be that I have Python 3 installed, but the program is being interpreted by Python 2.6. I'm using Linux Mint if that can help you guys help me. Using Geany as the IDE and pressing F5 to test it. It may be loading 2.6 by default, but I don't really know. :( Edit: Error 1 is: File "GuessingGame.py", line 8, in <Module> myName = input() Error 2 is: File <string>, line 1, in <Module>

    Hi, I am trying to validate the format of non-negative integers with the following validates_format_of :fundays, :with => /\A[\d]+\Z/, :message => "invalid fundays" And here is the form field used in the view <%= f.text_field :fundays, :maxlength => 3, :style => 'width:50px;' %> However, when I input a non-digit into this field and submit the form, it does not fail the validation. Instead it saves a value of 0 in the database. How do I make it write to the list of error messages. thanks

  • Submitting a form on 'Enter' with jQuery?

    - by b. e. hollenbeck
    I have a bog-standard login form - an email text field, a password field and a submit button on an AIR project that's using HTML/jQuery. When I hit Enter on the form, the entire form's contents vanish, but the form isn't submitted. Does anyone know if this is a Webkit issue (Adobe AIR uses Webkit for HTML), or if I've bunged things up? I tried: $('.input').keypress(function(e){ if(e.which == 13){ $('form#login').submit(); } }); But that neither stopped the clearing behavior, or submitted the form. There's no action associated with the form - could that be the issue? Can I put a javascript function in the action?

  • Changing constraints on the fly

    - by GoinOff
    Hi, I have a dijit.form.NumberTextBox input field that starts out with these parms: new dijit.form.NumberTextBox({ id: din1, style: "width:60px", constraints: { places: 0, pattern: '######' } }, din1); Everything works great..My question is I would like to change 'places' and 'pattern' parms on the fly. So I wrote this to change 'places' and 'patterns' parms: var myFldObj = dijit.byId(din1); if (myFldObj) { var myConstObj = myFldObj.attr('constraints'); if (myConstObj) { myConstObj.places = 2; myConstObj.pattern = '#####.0'; } } So, after I show the form again, I'd expect the entry field to allow 2 decimal places but the form still acts like places=0 and pattern='######'. When I check the values of 'places' and 'pattern' I get what I'd expect (2 and #####.0). My question: Can you change these values on the fly?? OR Do you have to destroy the original dijit object and recreate with new parms?? Thx!!

  • How can I put rows of MySQL data under the appropriate titles using PHP?

    - by sfarbota
    I have the following MySQL table structure: num field company phone website 1 Gas abcd 123456789 abcd.com 2 Water efgh 987654321 efgh.com 3 Water ijkl 321654987 ijkl.com 4 Heat mnop 987654321 mnop.com 5 Gas qrst 123789654 qrst.com ... Is it possible with PHP (maybe using some mixture of GROUP_BY and ORDER_BY) to echo the data to the screen in the following format: Gas: abcd qrst 123456789 123789654 abcd.com qrst.com Water: efgh ijkl 987654321 321654987 efgh.com ijkl.com Heat: mnop 321654987 mnop.com The exact format of it isn't important. I just need for the different rows of data to be listed under the appropriate field with none of the fields repeated. I've been trying to figure this out for a while now, but I'm new to PHP and I can't seem to figure out how to do this, if it's even possible, or if there's a better way to organize my data to make it easier.

  • CSS: how to set the width of form control so they all have the same width?

  • string categorization strategies

    - by Andrew Heath
    I'm the one-man dev team on a fledgling military history website. One aspect of the site is a catalog of ~1,200 individual battles, including the nations & formations (regiments, divisions, etc) which took part. The formation information (as well as the other battle info) was manually imported from a series of books by a 10-man volunteer team. The formations were listed in groups with varying formatting and abbreviation patterns. At the time I set up the data collection forms I couldn't think of a good way to process that data... and elected to store it all as strings in the MySQL database and sort it out later. Well, "later" - as it tends to happen - has arrived. :-) Each battle has 2+ records in the database - one for each nation that participated. Each record has a formations text string listing the formations present as the volunteer chose to add them. Some real examples: 39th Grenadier Rgmt, 26th Volksgrenadier Division 2nd Luftwaffe Field Division, 246th Infantry Division 247th Rifle Division, 255th Tank Brigade 2nd Luftwaffe Field Division, SS Cavalry Division 28th Tank Brigade, 158th Rifle Division, 135th Rifle Division, 81st Tank Brigade, 242nd Tank Brigade 78th Infantry Division 3rd Kure Special Naval Landing Force, Tulagi Seaplane Base personnel 1st Battalion 505th Infantry Regiment The ultimate goal is for each individual force to have an ID, so that its participation can be traced throughout the battle database. Formation hierarchy, such as the final item above 1st Battalion (of the) 505th Infantry Regiment also needs to be preserved. In that case, 1st Battalion and 505th Infantry Regiment would be split, but 1st Battalion would be flagged as belonging to the 505th. In database terms, I think I want to pull the formation field out of the current battle info table and create three new tables: FORMATION [id] [name] FORMATION_HIERARCHY [id] [parent] [child] FORMATION_BATTLE [f_id] [battle_id] It's simple to explain, but complicated to enact. What I'm looking for from the SO community is just some tips on how best to tackle this problem. Ideally there's some sort of method to solving this that I'm not aware of. However, as a last resort, I could always code a classification framework and call my volunteers back to sort through 2,500+ records...

  • Update multiple rows with one query?

    - by kavoir.com
    I found something that works with updating one field at here: http://www.karlrixon.co.uk/articles/sql/update-multiple-rows-with-different-values-and-a-single-sql-query/ UPDATE person SET name = CASE id WHEN 1 THEN 'Jim' WHEN 2 THEN 'Mike' WHEN 3 THEN 'Precious' END WHERE id IN (1,2,3) My question is how to update more than one field? Such as: UPDATE person SET name = CASE, sex = CASE id WHEN 1 THEN 'Jim', 'female' WHEN 2 THEN 'Mike' 'male' WHEN 3 THEN 'Precious', 'male' END WHERE id IN (1,2,3) Which doesn't work of course. Tried a few other combination and failed. Any idea? Thanks!

  • searching between dates in MYSQL in this format 03/17/10.11:22:45

    - by Kelso
    I have a script that automatically populates a mysql database with data every hour. It populates the date field like 03/17/10.12:34:11 and so on. I'm working on pulling data based on 1 day at a time from a search script. If i use select * from call_logs where call_initiated between '03/17/10.12:00:00' and '03/17/10.13:00:00' it works, but when I try to add the rest of the search params, it ignores the call_initiated field. select * from call_logs where caller_dn='2x9xxx0000' OR called_dn='2x9xxx0000' AND call_initiated between '03/17/10.12:00:00' and '03/17/10.13:00:00' ^-- I x'd out a couple of the numbers. I've also tried without the between function, and used = <= to pull the records, but have the same results. Im sure its an oversight, thanks in advance.

  • how do I insert an hidden token in my form to prevent double posts? (PHP)

    - by jpjp
    I want to prevent users from accidentally posting a comment twice. I use the PRG (post redirect get) method, so that I insert the data on another page then redirect the user back to the page which shows the comment. This allows users to refresh as many times as they want. However this doesn't work when the user goes back and clicks submit again or when they click submit 100 times really fast. I don't want 100 of the same comments. I looked at related questions on SO and found that a token is best. But I am having trouble using it. //makerandomtoken(20) returns a random 20 length char. <form method="post" ... > <input type="text" id="comments" name="comments" class="commentbox" /><br/> <input type="hidden" name="_token" value="<?php echo $token=makerandomtoken(20); ?>" /> <input type="submit" value="submit" name="submit" /> </form> if (isset($_POST['submit']) && !empty($comments)) { $comments= mysqli_real_escape_string($dbc,trim($_POST['comments'])); //how do I make the if-statment to check if the token has been already set once? if ( ____________){ //don't insert comment because already clicked submit } else{ //insert the comment into the database } } So I have the token as a hidden value, but how do I use that to prevent multiple clicking of submit.

  • Recognizing terminals in a CFG production previously not defined as tokens.

    - by kmels
    I'm making a generator of LL(1) parsers, my input is a CoCo/R language specification. I've already got a Scanner generator for that input. Suppose I've got the following specification: COMPILER 1. CHARACTERS digit="0123456789". TOKENS number = digit{digit}. decnumber = digit{digit}"."digit{digit}. PRODUCTIONS Expression = Term{"+"Term|"-"Term}. Term = Factor{"*"Factor|"/"Factor}. Factor = ["-"](Number|"("Expression")"). Number = (number|decnumber). END 1. So, if the parser generated by this grammar receives a word "1+1", it'd be accepted i.e. a parse tree would be found. My question is, the character "+" was never defined in a token, but it appears in the non-terminal "Expression". How should my generated Scanner recognize it? It would not recognize it as a token. Is this a valid input then? Should I add this terminal in TOKENS and then consider an error routine for a Scanner for it to skip it? How does usual language specifications handle this?

  • set a default saving data in a selection box in HABTM model

    - by vincent low
    here is my problem which in my system. my system allow user to add event, which include date, time, places. In the other hand, user are allow to choose the "Event sharing to" some of other user. So i successful to created and share to other user, when the user login which are being choose to share with the event, he is able to view for that particular event. But the problem is, when user add the event, he must choose for his own name also in the select box. If not he will be unable to read the event that he had created. So i need to save a default data to my model, which is whenever the user got choose the sharing event or not, it also will save the data to his user id. here is my code for select box, what can i edit and do to let it set a default saving value which is always save with the user own data?? input('User',array( 'label' = 'Select Related Potential', 'options' = $users, //'id'='user', 'style'='width:250px;height:100px', //'selected' = $ownUserId )); ? i try to solve by adding 1 more row to the add.ctp, but the permission just set to the own user who created it, the other user i choose is unable to read. $form-input('User',array( 'label' = 'Select Related Potential', 'options' = $users, //'id'='user', 'style'='width:250px;height:100px', 'selected' = $ownUserId )); $form-input('User',array('type'='hidden','value'=$ownUserId));

  • MS Access MSChart.Graph.8 not printing

    - by Tanj
    Software: Microsoft Access 2007 SP2 Database File Version: Access 2000 I have an access program that I inherited from a previous employee. It uses forms for reports and since I don't have much experience in access I have continued to do this. I have created a copy of the program for another project and modified it to suit. I am having trouble getting more then one chart to print. All the charts display in form view, they all have the same properties (excepting data, position, etc.) For some reason they are not printing. They don't even show up in the print preview. I am thinking it must be something with the graphs themselves as they sometimes lose all information. I have to open the graphs in edit mode and change the data source from column to row and back again so that it gets redrawn. (Refresh doesn't fix it) So right now I don't even have a clue as to where to look so ideas are welcome. Edit #1 It seems to be a problem with linking to an unbound form. Subform Field Linker: Can't build a link between unbound forms. The query for the main form is SELECT tTest.ixTest, tMotorTypes.ixMotorType, tMotorTypes.asMotorType, tMotorTypes.fDeprecated, tTestType.asTest, tTest.asSerialNum, tTest.asOrderNum, tTest.asFrameNum, tTest.asRotorNum, tTest.asOperator, tTest.iStation, tTest.dtTestDate, tTest.ixTestType FROM tMotorTypes INNER JOIN (tTestType INNER JOIN tTest ON tTestType.ixTestType=tTest.ixTestType) ON tMotorTypes.ixMotorType=tTest.ixMotorType; The query for the chart is: SELECT qGraphRSTTemperatures.Frequency, qGraphRSTTemperatures.[Drive End], qGraphRSTTemperatures.[Non Drive End], qGraphRSTTemperatures.[Air In], qGraphRSTTemperatures.Core FROM qGraphRSTTemperatures ORDER BY qGraphRSTTemperatures.ixTemperature; Query qGraphRSTTemperatures: SELECT tElectricalData.dblFrequency AS Frequency, tTemperatures.dblDrvEnd AS [Drive End], tTemperatures.dblNonDrvEnd AS [Non Drive End], tTemperatures.dblAirIn AS [Air In], tTemperatures.dblCore AS Core, tSubTest.ixTest, tTemperatures.ixTemperature FROM (tSubTest INNER JOIN tElectricalData ON tSubTest.ixSubTest = tElectricalData.ixSubTest) LEFT JOIN tTemperatures ON tElectricalData.ixElectrical = tTemperatures.ixElectrical WHERE (((tSubTest.ixSubTestType)=5)) ORDER BY tSubTest.ixTest, tTemperatures.ixTemperature; So how come, in the form view it shows the graph with the correct data when linked thus: Child field: ixTest Master field: ixTest but won't print the graph. The graph will print if I remove the links, but then I have all the data from chart query as it is not limited by ixTest. edit #2 It seems to be a data retrieval/rendering issue in printing. Is there anything in printing that changes the context of records with respect to parent/child relationships?
