  • MS Access Can't move to a different record?

    - by user986706
    Ok, I'm really baffled. Here's the rundown: I've created a form with a subform. The main form is called FacilityInfo, and the subform is called BillingInfo. The forms are linked via 3 fields, AffiliateID, ClientID, and FacilityID. the subform shows one record at a time, set to show Continuous Forms, and AllowAdditions = No I can see that there are 4 records in the nav bar. But Access won't let me move off the first record. I've tried setting to Single Form. I've tried AllowAdditions = Yes. I do have a Vertical Scroll bar on the subform. It will allow me to scroll through the records, but I can only see them. I cannot move to one of the controls. Any ideas? I'm freakin' out! Thanks in advance!

  • Logging errors caused by exceptions deep in the application

    - by Kaleb Pederson
    What are best-practices for logging deep within an application's source? Is it bad practice to have multiple event log entries for a single error? For example, let's say that I have an ETL system whose transform step involves: a transformer, pipeline, processing algorithm, and processing engine. In brief, the transformer takes in an input file, parses out records, and sends the records through the pipeline. The pipeline aggregates the results of the processing algorithm (which could do serial or parallel processing). The processing algorithm sends each record through one or more processing engines. So, I have at least four levels: Transformer - Pipeline - Algorithm - Engine. My code might then look something like the following: class Transformer { void Process(InputSource input) { try { var inRecords = _parser.Parse(input.Stream); var outRecords = _pipeline.Transform(inRecords); } catch (Exception ex) { var inner = new ProcessException(input, ex); _logger.Error("Unable to parse source " + input.Name, inner); throw inner; } } } class Pipeline { IEnumerable<Result> Transform(IEnumerable<Record> records) { // NOTE: no try/catch as I have no useful information to provide // at this point in the process var results = _algorithm.Process(records); // examine and do useful things with results return results; } } class Algorithm { IEnumerable<Result> Process(IEnumerable<Record> records) { var results = new List<Result>(); foreach (var engine in Engines) { foreach (var record in records) { try { engine.Process(record); } catch (Exception ex) { var inner = new EngineProcessingException(engine, record, ex); _logger.Error("Engine {0} unable to parse record {1}", engine, record); throw inner; } } } } } class Engine { Result Process(Record record) { for (int i=0; i<record.SubRecords.Count; ++i) { try { Validate(record.subRecords[i]); } catch (Exception ex) { var inner = new RecordValidationException(record, i, ex); _logger.Error( "Validation of subrecord {0} failed for record {1}", i, record ); } } } } There's a few important things to notice: A single error at the deepest level causes three log entries (ugly? DOS?) Thrown exceptions contain all important and useful information Logging only happens when failure to do so would cause loss of useful information at a lower level. Thoughts and concerns: I don't like having so many log entries for each error I don't want to lose important, useful data; the exceptions contain all the important but the stacktrace is typically the only thing displayed besides the message. I can log at different levels (e.g., warning, informational) The higher level classes should be completely unaware of the structure of the lower-level exceptions (which may change as the different implementations are replaced). The information available at higher levels should not be passed to the lower levels. So, to restate the main questions: What are best-practices for logging deep within an application's source? Is it bad practice to have multiple event log entries for a single error?

  • Fread binary file dynamic size string [C]

    - by Blackbinary
    I've been working on this assignment, where I need to read in "records" and write them to a file, and then have the ability to read/find them later. On each run of the program, the user can decide to write a new record, or read an old record (either by Name or #) The file is binary, here is its definition: typedef struct{ char * name; char * address; short addressLength, nameLength; int phoneNumber; }employeeRecord; employeeRecord record; The way the program works, it will store the structure, then the name, then the address. Name and address are dynamically allocated, which is why it is necessary to read the structure first to find the size of the name and address, allocate memory for them, then read them into that memory. For debugging purposes I have two programs at the moment. I have my file writing program, and file reading. My actual problem is this, when I read a file I have written, i read in the structure, print out the phone # to make sure it works (which works fine), and then fread the name (now being able to use record.nameLength which reports the proper value too). Fread however, does not return a usable name, it returns blank. I see two problems, either I haven't written the name to the file correctly, or I haven't read it in correctly. Here is how i write to the file: where fp is the file pointer. record.name is a proper value, so is record.nameLength. Also i am writing the name including the null terminator. (e.g. 'Jack\0') fwrite(&record,sizeof record,1,fp); fwrite(record.name,sizeof(char),record.nameLength,fp); fwrite(record.address,sizeof(char),record.addressLength,fp); And i then close the file. here is how i read the file: fp = fopen("employeeRecord","r"); fread(&record,sizeof record,1,fp); printf("Number: %d\n",record.phoneNumber); char *nameString = malloc(sizeof(char)*record.nameLength); printf("\nName Length: %d",record.nameLength); fread(nameString,sizeof(char),record.nameLength,fp); printf("\nName: %s",nameString); Notice there is some debug stuff in there (name length and number, both of which are correct). So i know the file opened properly, and I can use the name length fine. Why then is my output blank, or a newline, or something like that? (The output is just Name: with nothing after it, and program finishes just fine) Thanks for the help.

  • Query for rows including child rows

    - by MAD9
    A few weeks ago, I asked a question about how to generate hierarchical XML from a table, that has a parentID column. It all works fine. The point is, according to the hierarchy, I also want to query a table. I'll give you an example: Thats the table with the codes: ID CODE NAME PARENTID 1 ROOT IndustryCode NULL 2 IND Industry 1 3 CON Consulting 1 4 FIN Finance 1 5 PHARM Pharmaceuticals 2 6 AUTO Automotive 2 7 STRAT Strategy 3 8 IMPL Implementation 3 9 CFIN Corporate Finance 4 10 CMRKT Capital Markets 9 From which I generate (for displaying in a TreeViewControl) this XML: <record key="1" parentkey="" Code="ROOT" Name="IndustryCode"> <record key="2" parentkey="1" Code="IND" Name="Industry"> <record key="5" parentkey="2" Code="PHARM" Name="Pharmaceuticals" /> <record key="6" parentkey="2" Code="AUTO" Name="Automotive" /> </record> <record key="3" parentkey="1" Code="CON" Name="Consulting"> <record key="7" parentkey="3" Code="STRAT" Name="Strategy" /> <record key="8" parentkey="3" Code="IMPL" Name="Implementation" /> </record> <record key="4" parentkey="1" Code="FIN" Name="Finance"> <record key="9" parentkey="4" Code="CFIN" Name="Corporate Finance"> <record key="10" parentkey="9" Code="CMRKT" Name="Capital Markets" /> </record> </record> </record> As you can see, some codes are subordinate to others, for example AUTO << IND << ROOT What I want (and have absolutely no idea how to realise or even, where to start) is to be able to query another table (where one column is this certain code of course) for a code and get all records with the specific code and all subordinate codes For example: I query the other table for "IndustryCode = IND[ustry]" and get (of course) the records containing "IND", but also AUTO[motive] and PHARM[aceutical] (= all subordinates) Its an SQL Express Server 2008 with Advanced Services.

  • Generating different randoms valid for a day on different independent devices?

    - by Pentium10
    Let me describe the system. There are several mobile devices, each independent from each other, and they are generating content for the same record id. I want to avoid generating the same content for the same record on different devices, for this I though I would use a random and make it so too cluster the content pool based on these randoms. Suppose you have choices from 1 to 100. Day 1 Device#1 will choose for the record#33 between 1-10 Device#2 will choose for the record#33 between 40-50 Device#3 will choose for the record#33 between 50-60 Device#1 will choose for the record#55 between 40-50 Device#2 will choose for the record#55 between 1-10 Device#3 will choose for the record#55 between 10-20 Device#1 will choose for the record#11 between 1-10 Device#2 will choose for the record#22 between 1-10 Device#3 will choose for the record#99 between 1-10 Day 2 Device#1 will choose for the record#33 between 90-100 Device#2 will choose for the record#33 between 1-10 Device#3 will choose for the record#33 between 50-60 They don't have access to a central server. Data available for each of them: IMEI (unique per mobile) Date of today (same on all devices) Record id (same on all devices) What do you think, how is it possible? ps. tags can be edited

  • Ubuntu getting wrong hostname from DHCP

    - by sam
    When provisioning new Ubuntu Precise (12.04) servers, the hostname they're getting seems to be generated from the DNS search path, not a reverse lookup on the hostname. Take the following configuration BIND is configured with the hostname, and reverse name Normal zone $TTL 600 $ORIGIN srv.local.net. @ IN SOA ns0.local.net. hostmaster.local.net. ( 2014082101 10800 3600 604800 600 ) @ IN NS ns0.local.net. @ IN MX 5 mail.local.net. my-new-server IN A 10.32.2.30 And reverse @ IN SOA ns0.local.net. hostmaster.local.net. ( 2014082101 10800 3600 604800 600 ) @ IN NS ns0.local.net. $ORIGIN 32.10.in-addr.arpa. 30.2 IN PTR my-new-server.srv.local.net. Then DHCPD is configured to hand out static leases based on mac addresses like so subnet 10.32.2.0 netmask 255.255.254.0 { option subnet-mask 255.255.254.0; option routers 10.32.2.1; option domain-name-servers 10.32.2.1; option domain-name "util.of1.local.net of1.local.net srv.local.net"; site-option-space "pxelinux"; option pxelinux.magic f1:00:74:7e; if exists dhcp-parameter-request-list { option dhcp-parameter-request-list = concat(option dhcp-parameter-request-list,d0,d1,d2,d3); } group { option pxelinux.configfile "pxelinux.cfg/pxeboot"; host my-new-server { fixed-address my-new-server.srv.local.net; hardware ethernet aa:aa:aa:bb:bb:bb; } } } So the hostname should be my-new-server.srv.local.net, however when building a Ubuntu 12.04 node, the hostname ends up as my-new-server.util.of1.local.net When building Lucid (10.04) hosts, the hostname will be correct, it's only on Precise/12.04 nodes we have the problem. Doing a normal and reverse lookup on the host and IP returns the correct result Sams-MacBook-Pro:~ sam$ host my-new-server my-new-server.srv.local.net has address 10.32.2.30 Sams-MacBook-Pro:~ sam$ host my-new-server.srv.local.net my-new-server.srv.local.net has address 10.32.2.30 Sams-MacBook-Pro:~ sam$ host 10.32.2.30 30.2.32.10.in-addr.arpa domain name pointer my-new-server.srv.local.net. The contents of the hosts file is incorrect too 127.0.0.1 localhost 127.0.1.1 my-new-server.util.of1.local.net of1.local.net srv.local.net my-new-server So it looks like when it creates the hosts file, it puts the entire contents of the DNS search path into the local address so the FQDN according to the server is the short hostname as defined, then the first domain in the search path. Is there a way to get around this behaviour, or fix this so it gets the hostname correctly? It's picking up the first part of the hostname, then the rest is wrong.

  • How to change the "record external input" in Fraps?

    - by CyanPrime
    I'm using a TV to USB capture thingy called Hauppauge USB-Live2 (http://www.hauppauge.com/site/products/data_usblive2.html) and I'm using Media Player Classic Home Cinema to view my device's output, and finally I'm using Fraps to record the output off of MPC. It all works nicely except I can't get my mic to record, or even show up in the "Record External Input" area of Fraps while my Hauppauge is plugged in. My question is: How can I select my mic as the "record external input" in fraps?

  • Apache2 Virtual Host broken; displayed default index.html on subdomain, but correct content on www.subdomain

    I've got a Linode configured as a Ubuntu 10.04.2 web server with Apache 2.2.14. I have a total of 4 sites, all defined under /etc/apache2/sites-available as virtual hosts. All sites are almost identical clones for configuration. And all sites but my last work successfully. default: (www.)exampleadnetwork.com (www.)example.com reseller.example.com trouble: client1.example.com I keep getting this page when I visit the client1.example.com site: It works! This is the default web page for this server. The web server software is running but no content has been added, yet. In my ports.conf file I have the NameVirtualHost correctly set to my IP address on port 80. If I access the "www.sub.example.com" alias the site works! If I access it without the www I see the "It Works" excerpt posted above. Even apache2ctl -S shows that my vhost file parses correctly and is added to the mix.

  • Adding new record to a VFP data table in VB.NET with ADO recordsets

    - by Gerry
    I am trying to add a new record to a Visual FoxPro data table using an ADO dataset with no luck. The code runs fine with no exceptions but when I check the dbf after the fact there is no new record. The mDataPath variable shown in the code snippet is the path to the .dbc file for the entire database. A note about the For loop at the bottom; I am adding the body of incoming emails to this MEMO field so thought I needed to break the addition of this string into 256 character Chunks.

  • AVAudioRecorder Won't Record On Device

Everything works in the simulator however, when I run it on a device, [recorder record] returns NO. Does anyone have a clue as to why this is happening?

  • Ability to draw and record a signature as part of a form - iphone

    - by mustic
    Apolgies in advance for any errors.. new to this and am not a developer/programmer.. just have some basic unix experience. I have searched the web and struggled to find a solution to my problem when I stumbled onto this website which maybe suggested that there is a solution to my question. For work i use a windows mobile device because we have to get customers to sign and form after a customer visit. the signature being very important. On the windows device i use the notes application and am able to record details and obtain/record (using draw) a customer signature. the form is then emailed back to HQ. The format being used is a *.pwi I have downloaded and paid for several applications for my iphone which is my preferred device and cant quite find anything that does both. the critical bit here is to be able to take a signature on the phone, save the doc in a format such as .txt, .doc or .pdf where i can control the file name then be able to email back to HQ. Am i asking too much? I hope that makes sense.. Any help would be much appreciated many thanks in advance

  • Active Record two belongs_to calls or single table inheritance

    - by ethyreal
    In linking a sports event to two teams, at first this seemed to make sense: events - id:integer - integer:home_team_id - integer:away_team_id teams - integer:id - string:name However I am troubled by how I would link that up in the active record model: class Event belongs_to :home_team, :class_name => 'Team', :foreign_key => "home_team_id" belongs_to :away_team, :class_name => 'Team', :foreign_key => "away_team_id" end Is that the best solution? In an answer to a similar question I was pointed to single table inheritance, and then later found polymorphic associations. Neither of which seemed to fit this association. Perhaps I am looking at this wrong, but I see no need to subclass a team into home and away teams since the distinction is only in where the game is played. If I did go with single table inheritance I wouldn't want each team to belong_to an event so would this work? # app/models/event.rb class Event < ActiveRecord::Base belongs_to :home_team belongs_to :away_team end # app/models/team.rb class Team < ActiveRecord::Base has_many :teams end # app/models/home_team.rb class HomeTeam < Team end # app/models/away_team.rb class AwayTeam < Team end I thought also about a has_many through association but that seems two much as I will only ever need two teams, but those two teams don't belong to any one event. event_teams - integer:event_id - integer:team_id - boolean:is_home Is there a cleaner more semantic way for making these associations in active record? or is one of these solutions the best choice? Thanks

  • Displaying tree path of record in SQL Server 2005

    - by jskiles1
    An example of my tree table is: ([id] is an identity) [id], [parent_id], [path] 1, NULL, 1 2, 1, 1-2 3, 1, 1-3 4, 3, 1-3-4 My goal is to query quickly for multiple rows of this table and view the full path of the node from its root, through its superiors, down to itself. The ultimate question is, should I generate this path on inserts and maintain it in its own column or generate this path on query to save disk space? I guess it depends if this table is write heavy or read heavy. I've been contemplating several approaches to using the "path" characteristic of this parent/child relationship and I just can't seem to settle on one. This "path" is simply for display purposes and serves absolutely no purpose other than that. Here is what I have done to implement this "path." AFTER INSERT TRIGGER - requires passing a NULL path to the insert and updating the path for the record at the inserted rows identity INSTEAD OF INSERT TRIGGER - does not require insert to have NULL path passed, but does require the trigger to insert with a NULL path and updating the path for the record at SCOPE_IDENTITY() STORED PROCEDURE - requiring all inserts into this table to be done through the stored procedure implementing the trigger logic VIEW - requires building the path in the view 1 and 2 seem annoying if massive amounts of data are entered at once. 3 seems annoying because all inserts must go through the procedure in order to have a valid path populated. 1, 2, and 3 require maintaining a path column on the table. 4 removes all the limitations of the above but require the view to perform the path logic and requires use of the view if a path is to be displayed. I have successfully implemented all of the above approaches and I'm mainly looking for some advice. Am I way off the mark here or are any of the above acceptable? Each has it's advantages and disadvantages.

  • How to record video in iphone

    - by Timmi
    HI, I need to record video using iPhone. To do that i used UIImagePickerController. I have an iPhone 3G, with me. when i run my code to check if source type available it says device not supported. My OS is 3.2.1, where i am wrong, can some one tell me what i need to change. Also is there some other way to record video. What i need to do is to get the video stream as it is recorded. UIImagePickerController *picker = [[UIImagePickerController alloc] init]; picker.delegate = self; NSArray *sourceTypes = [UIImagePickerController availableMediaTypesForSourceType:picker.sourceType]; if (![sourceTypes containsObject:(NSString *)kUTTypeVideo ]){ NSLog(@"device not supported"); return; } //picker.allowsEditing = YES; picker.sourceType = UIImagePickerControllerSourceTypeCamera; picker.mediaTypes = [NSArray arrayWithObject:(NSString *)kUTTypeVideo]; picker.videoQuality = UIImagePickerControllerQualityTypeHigh; [self presentModalViewController:picker animated:YES]; Thanks,

  • Need to get 3 record for database on current date using sqlite

    - by Umaid
    SELECT rowid, Day, Advice from MainCategory where ((Day = ((cast(strftime('%d',date('now','-1 day')) as Integer)))) and (Month = (strftime('%m',date('now'))))) and ((Day = ((cast(strftime('%d',date('now')) as Integer)))) and (Month = (strftime('%m',date('now'))))) , ((Day = ((cast(strftime('%d',date('now','+1 day')) as Integer)))) and (Month = (strftime('%m',date('now',+1 month))))); What if i make my Month column in Integer data type then it would be. SELECT rowid, Month, Day, Advice from MainCategory where ((Day = ((cast(strftime('%d',date('now','-1 day')) as Integer)))) and (Month = (strftime('%m',date('now'))))) and ((Day = ((cast(strftime('%d',date('now')) as Integer)))) and (Month = (strftime('%m',date('now'))))) , ((Day = ((cast(strftime('%d',date('now','+1 day')) as Integer)))) and (Month = (strftime('%m',date('now',+1 month))))); Please note that I have over this scenerio when I am in middle of month but below query returns 2 records and 1 from begining from all 11 months as (feb is exclusive) then record will be 33 but i need three 3 records from the table and increment it on next button. Please write 3 querys one which return all three record on current date, next all 3 records must be incremented by 1 on every next button click finally all 3 records must be decremented by 1 on every previous button click keep last day and begining date on the month in minds else i have also achieved for middle of month. Running query but returns 33 records instead of 3. SELECT rowid,Month, Day, Advice from MainCategory where Day in ((cast(strftime('%d',date('now','-1 day')) as Integer)),(cast(strftime('%d',date('now')) as Integer)),(cast(strftime('%d',date('now','+1 day')) as Integer)));

  • Query next/previous record

    - by Rob
    I'm trying to find a better way to get the next or previous record from a table. Let's say I have a blog or news table: CREATE TABLE news ( news_id INT UNSIGNED NOT NULL PRIMARY KEY AUTO_INCREMENT, news_datestamp DATETIME NOT NULL, news_author VARCHAR(100) NOT NULL, news_title VARCHAR(100) NOT NULL, news_text MEDIUMTEXT NOT NULL ); Now on the frontend I want navigation buttons for the next or previous records, if i'm sorting by news_id, I can do something rather simple like: SELECT MIN(news_id) AS next_news_id FROM news WHERE news_id > '$old_news_id' LIMIT 1 SELECT MAX(news_id) AS prev_news_id FROM news WHERE news_id < '$old_news_id' LIMIT 1 But the news can be sorted by any field, and I don't necessarily know which field is sorted on, so this won't work if the user sorts on news_author for example. I've resorted to the rather ugly and inefficient method of sorting the entire table and looping through all records until I find the record I need. $res = mysql_query("SELECT news_id FROM news ORDER BY `$sort_column` $sort_way"); $found = $prev = $next = 0; while(list($id) = mysql_fetch_row($res)) { if($found) { $next = $id; break; } if($id == $old_news_id) { $found = true; continue; } $prev = $id; } There's got to be a better way.

  • Insert Stored Procedure does not Create Database Record

    - by SidC
    Hello All, I have the following stored procedure: ALTER PROCEDURE Pro_members_Insert @id int outPut, @LoginName nvarchar(50), @Password nvarchar(15), @FirstName nvarchar(100), @LastName nvarchar(100), @signupDate smalldatetime, @Company nvarchar(100), @Phone nvarchar(50), @Email nvarchar(150), @Address nvarchar(255), @PostalCode nvarchar(10), @State_Province nvarchar(100), @City nvarchar(50), @countryCode nvarchar(4), @active bit, @activationCode nvarchar(50) AS declare @usName as varchar(50) set @usName='' select @usName=isnull(LoginName,'') from members where LoginName=@LoginName if @usName <> '' begin set @ID=-3 RAISERROR('User Already exist.', 16, 1) return end set @usName='' select @usName=isnull(email,'') from members where Email=@Email if @usName <> '' begin set @ID=-4 RAISERROR('Email Already exist.', 16, 1) return end declare @MemID as int select @memID=isnull(max(ID),0)+1 from members INSERT INTO members ( id, LoginName, Password, FirstName, LastName, signupDate, Company, Phone, Email, Address, PostalCode, State_Province, City, countryCode, active,activationCode) VALUES ( @Memid, @LoginName, @Password, @FirstName, @LastName, @signupDate, @Company, @Phone, @Email, @Address, @PostalCode, @State_Province, @City, @countryCode, @active,@activationCode) if @@error <> 0 set @ID=-1 else set @id=@memID Note that I've "inherited" this sproc and the database. I am trying to insert a new record from my signup.aspx page. My SQLDataSource is as follows: <asp:SqlDataSource runat="server" ID="dsAddMember" ConnectionString="rmsdbuser" InsertCommandType="StoredProcedure" InsertCommand="Pro_members_Insert" ProviderName="System.Data.SqlClient"> The click handler for btnSave is as follows: Protected Sub btnSave_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnSave.Click Try dsAddMember.DataBind() Catch ex As Exception End Try End Sub When I run this page, signup.aspx, provide required fields and click submit, the page simply reloads and the database table does not reflect the newly-inserted record. Questions: 1. How do I catch the error messages that might be returned from the sproc? 2. Please advise how to change signup.aspx so that the insert occurs. Thanks, Sid
