  • MinGw Multiple Definitions

    - by makuto
    I'm trying to get the MinGw C++ compiler set up so I can compile my code for Windows computers and I'm having troubles. I originally installed minGw32 but then found that mingw-w64 was a better fit for me, so I uninstalled minGw32 and installed mingw-w64. The problem is that when I try to compile a simple hello world application I get Multiple Definition errors (which are not from my code). I'm thinking it has something to do with the removal of w32 and the installation of w64 without a clean directory. How do/should I clean the necessary folders & get rid of those multiple definitions.

  • Jumping Login Box after Lighdm Multiple Monitor workaround

    - by Tom Gamon
    So I used this workaround to sort my resolution at the login screen when using multiple monitors with Lightdm. #!/bin/bash XCOM0=`xrandr -q | grep 'VGA1 connected'` XCOM1=`xrandr --output LVDS1 --primary --auto --output VGA1 --auto --right-of LVDS1` XCOM2=`xrandr --output LVDS1 --primary --auto` # if the external monitor is connected, then we tell XRANDR to set up an extended desktop if [ -n "$XCOM0" ] || [ ! "$XCOM0" = "" ]; then echo $XCOM1 # if the external monitor is disconnected, then we tell XRANDR to output only to the laptop screen else echo $XCOM2 fi exit 0; Found Here: How to force Multiple Monitors correct resolutions for LightDM? It works great. However, now when I am on my login screen, the login box seems to jump to between the two displays. Any advice as to how I could make it stay on one display? Thanks

In this talk, I discussed a Master/Detail application that runs on Android 2.2 devices and forward. I used the Actionbar compat Android library to allow the older devices to have an actionbar. I also used a SQLite database for my data. And just to add one last thing, I also incorporated the use of custom fonts. If you are interesting in looking at this sample application, I have uploaded it to my GitHub account here. I also have a Power Point presentation which you can get here.I will be doing this talk again at a later date this year, so when I have a date and location, I will post a follow up blog.

  • Making Infragistics ultrawingrid, desired columns readonly

    - by Amit Ranjan
    I am stucked at the situation where I need to disable few columns of a each row ,except newly added row. That is I have 10 columns in grid and I want first three columns that are binded from the rows coming from db as disabled or read-only, rest are editable. if I add new row then all columns of new row must be enabled until and unless it is saved. I dont have any DataKey or Primary key for my existing row or new row. I have to check for some boolean values like IsNewRow. in my current scenario i am using this code block Private Sub dgTimeSheet_InitializeRow(ByVal sender As Object, ByVal e As Infragistics.Win.UltraWinGrid.InitializeRowEventArgs) Handles dgTimeSheet.InitializeRow ''if either column key is Project, Class or Milestone '' Activation.NoEdit = Disable and Activation.AllowEdit = Enable Dim index As Integer = e.Row.Index If e.Row.IsAddRow Then dgTimeSheet.Rows(index).Cells(PROJECT).Activation = Activation.AllowEdit dgTimeSheet.Rows(index).Cells(SERVICE_ISSUE_CLASS).Activation = Activation.AllowEdit dgTimeSheet.Rows(index).Cells(MILESTONE).Activation = Activation.AllowEdit Else dgTimeSheet.Rows(index).Cells(PROJECT).Activation = Activation.NoEdit dgTimeSheet.Rows(index).Cells(SERVICE_ISSUE_CLASS).Activation = Activation.NoEdit dgTimeSheet.Rows(index).Cells(MILESTONE).Activation = Activation.NoEdit End If CheckRows() End Sub but the problem is that if i click on disabled/readonly rows then newly added rows also gets disabled., which i dont want

  • Parsing large delimited files with dynamic number of columns

    - by annelie
    Hi, What would be the best approach to parse a delimited file when the columns are unknown before parsing the file? The file format is Rightmove v3 (.blm), the structure looks like this: #HEADER# Version : 3 EOF : '^' EOR : '~' #DEFINITION# AGENT_REF^ADDRESS_1^POSTCODE1^MEDIA_IMAGE_00~ // can be any number of columns #DATA# agent1^the address^the postcode^an image~ agent2^the address^the postcode^^~ // the records have to have the same number of columns as specified in the definition, however they can be empty etc #END# The files can potentially be very large, the example file I have is 40Mb but they could be several hundred megabytes. Below is the code I had started on before I realised the columns were dynamic, I'm opening a filestream as I read that was the best way to handle large files. I'm not sure my idea of putting every record in a list then processing is any good though, don't know if that will work with such large files. List<string> recordList = new List<string>(); try { using (FileStream fs = new FileStream(path, FileMode.Open, FileAccess.Read)) { StreamReader file = new StreamReader(fs); string line; while ((line = file.ReadLine()) != null) { string[] records = line.Split('~'); foreach (string item in records) { if (item != String.Empty) { recordList.Add(item); } } } } } catch (FileNotFoundException ex) { Console.WriteLine(ex.Message); } foreach (string r in recordList) { Property property = new Property(); string[] fields = r.Split('^'); // can't do this as I don't know which field is the post code property.PostCode = fields[2]; // etc propertyList.Add(property); } Any ideas of how to do this better? It's C# 3.0 and .Net 3.5 if that helps. Thanks, Annelie

  • Python DictReader - Skipping rows with missing columns?

    - by victorhooi
    heya, I have a Excel .CSV file I'm attempting to read in with DictReader. All seems to be well, except it seems to omit rows, specifically those with missing columns. Our input looks like: mail,givenName,sn,lorem,ipsum,dolor,telephoneNumber [email protected],ian,bay,3424,8403,2535,+65(2)34523534545 [email protected],mike,gibson,3424,8403,2535,+65(2)34523534545 [email protected],ross,martin,,,,+65(2)34523534545 [email protected],david,connor,,,,+65(2)34523534545 [email protected],chris,call,3424,8403,2535,+65(2)34523534545 So some of the rows have missing lorem/ipsum/dolor columns, and it's just a string of commas for those. We're reading it in with: def read_gd_dump(input_file="blah 20100423.csv"): gd_extract = csv.DictReader(open('blah 20100423.csv'), restval='missing', dialect='excel') return dict([(row['something'], row) for row in gd_extract]) And I checked that "something" (the key for our dict) isn't one of the missing columns, I had originally suspected it might be that. It's one of the columns after that. However, DictReader seems to completely skip over the rows. I tried setting restval to something, didn't seem to make any difference. I can't seem to find anything in Python's CSV docs (http://docs.python.org/library/csv.html) that would explain this behaviour, but I may have misread something. Any ideas? Thanks, Victor

  • mysql: Average over multiple columns in one row, ignoring nulls

    - by Sai Emrys
    I have a large table (of sites) with several numeric columns - say a through f. (These are site rankings from different organizations, like alexa, google, quantcast, etc. Each has a different range and format; they're straight dumps from the outside DBs.) For many of the records, one or more of these columns is null, because the outside DB doesn't have data for it. They all cover different subsets of my DB. I want column t to be their weighted average (each of a..f have static weights which I assign), ignoring null values (which can occur in any of them), except being null if they're all null. I would prefer to do this with a simple SQL calculation, rather than doing it in app code or using some huge ugly nested if block to handle every permutation of nulls. (Given that I have an increasing number of columns to average over as I add in more outside DB sources, this would be exponentially more ugly and bug-prone.) I'd use AVG but that's only for group by, and this is w/in one record. The data is semantically nullable, and I don't want to average in some "average" value in place of the nulls; I want to only be counting the columns for which data is there. Is there a good way to do this? Ideally, what I want is something like UPDATE sites SET t = AVG(a*a_weight,b*b_weight,...) where any null values are just ignored and no grouping is happening.

  • Help on understanding multiple columns on an index?

    - by Xaisoft
    Assume I have a table called "table" and I have 3 columns, a, b, and c. What does it mean to have a non-clustered index on columns a,b? Is a nonclustered index on columns a,b the same as a nonclustered index on columns b,a? (Note the order). Also, Is a nonclustered index on column a the same as a nonclustered index on a,c? I was looking at the website sqlserver performance and they had these dmv scripts where it would tell you if you had overlapping indexes and I believe it was saying that having an index on a is the same as a,b, so it is redundant. Is this true about indexes? One last question is why is the clustered index put on the primary key. Most of the time the primary key is not queried against, so shouldn't the clustered index be on the most queried column. I am probably missing something here like having it on the primary key speeds up joins? Great explanations. Should I turn this into a wiki and change the title index explanation?

  • R : remove columns from dataframe where ALL values are NA

    - by Sophomore
    hello everybody! I'm having some trouble with my huge data frame and couldn't really resolve that question myself: The dataframe has some properties as columns and each row represents one data set. I've done some sanatizing to this dataframe (e.g. get rid of datasets which are not to be included in evaluation). (Whoever might be interested: Beforehand I aggregate around 5000 single text files and put them in a tsv, some of the proerties have a sequence number like "button.pressed.1" ... ""button.pressed.n". Some of the sets excluded had really high numbers for n but got excluded, all sets left have much smaller numbers for n but the property "button.presed.50" is still there and all remaining sets have an NA in that column. Actually its a different property but the example should clarify my intention...) So the question is quite simple (for some sophisticated R pro): I need to get rid of columns where for ALL rows the value is NA. Could someone please help me out? (All I have managed to get rid of columns where at least one NA exists which dropped about half my columns)...

  • SQL Structure of DB table with different types of columns

    - by Dmitry Dvornikov
    I have a problem with the optimization of the structure of the database. I'll try to explain it exactly. I create a project, where we can add different values??, but this values must have different types of the columns in the database (eg, int, double , varchar). What is the best way to store the different types of values ??in the database. In the project I'm using Propel 1.6. The point is availability to add value with 'int', 'varchar' and other columns types, to search the table was efficient. In total, I have two ideas. The first is to create a table of "value", which will have columns: "id ", "value_int", "value_double", "value_varchar", etc - with the corresponding column types. Depending on the type of values??, records will be saved with the value in the appropriate column (the rest will be NULL). The second solution is to create separate tables such as "value_int", "value_varchar" etc. There would be columns: "id", "value", which correspond to the relevant types of "value" (ie, such as int, varchar, etc). I must admit that I do not believe any of the above solutions, originally I was thinking about one table "value", where the column would be a "text" type - but this solution would probably be even worse. I would like to know your opinion on this topic, maybe something else would be better. Thanks in advance. EDIT: For example : We have three tables: USER: [table of users] * id * name FIELD: [table of profile fields - where the column 'type' is the type of field, eg int or varchar) * id * type * name VALUE : * id * User_id - ( FK user.id ) * Field_id - ( FK field.id ) * value So we have in each row an user in USER table, and the profile is stored in the VALUE table. Bit each profile field may have a different type (column 'type' in the FIELD table), and based on that I would want this value to add to the appropriate column of the appropriate type.

  • Excel VBA - How to copy/transpose multiple columns record into individual single row

    - by larry
    I'm working on data migration, need some help on doing a macro to copy/transpose multiple columns record into individual single row. There are also a "tag" in the first row, which indicates the columns that should not be included in the copy/transpose. From: Tag x Name Jan Feb Mar Apr Larry 2 20 34 56 Harry 3 45 77 88 Marry 5 66 44 33 To: Larry Jan 2 Larry Feb 20 Larry Apr 56 Harry Jan 3 Harry Feb 45 Harry Apr 88 Marry Jan 5 Marry Feb 66 Marry Apr 33 The "Mar" data was omitted due to there's a tag (X) above it. The data might be near hundred columns (few years), and some of the months need to be omitted. Any expert able to help on this? I had been spending whole day cracking my head on this. Worse come to worse I might have to manually copy and paste, that would probably took me a decade.

  • ASP.NET GridView - Editing Dynamic Template Columns

    - by user208662
    Hello, I have created a GridView whose columns are dynamically created based on my data source. I have implemented these columns by using the approach described here.Those columns display properly on the initial load. However, I need to implement commanding so that a user can edit / delete a row in the GridView. At this point, I have implemented commanding as I would with a normal GridView. I have a TemplateField with an ItemTemplate that has LinkButton elements for edit and delete. The CommandName for each LinkButton is set to either Edit or Delete respectively. Oddly, when a user clicks either the Edit or Delete link, the data in the GridView disappears. However, I have verified that I am in fact re-binding the data when one of these LinkButton elements is selected. Can anyone provide some suggestions as to what the cause could be? Thank you!

  • C# GridView dynamically built columns with textboxes ontextchanged

    - by tnriverfish
    My page is a bulk order form that has many products and various size options. I've got a gridview that has a 3 static columns with labels. There are then some dynamically built columns. Each of the dynamically built columns have a textbox in them. The textbox is for quantity. Trying to either update the server with the quantity entered each time a textbox is changed (possibly ontextchanged event) or loop though each of the rows column by column and gather all the items that have a quantity and process those items and their quantities all at once (via button onclick). If I put the process that builds the GridView behind a if(!Page.IsPostBack) then the when a textchanged event fires the gridview only gets the static fields and the dynamic ones are gone. If I remove the if(!Page.IsPostBack) the process to gather and build the page is too heavy on processing and takes too long to render the page again. Some advice would be appreciated. Thanks

  • telerik mvc grid access cell data to enable columns.Command

    - by AZee
    Hi! I can't seem to find a way to reference the value in a column in the grid, in my case it is the StatusId. Based on the cell value in this row, for the StatusId, I need to return a true or false to the method ".Visible(???)". It would be nice to find the answer in the documentation online but I haven't been able to. I find it hard to believe that I would be the first person who ever needed this functionality. I would be most appreciative of any assistance since no one in the telerik forums know. .Columns(columns => { columns.Command(commands => { commands.Edit().ButtonType(ButtonType); commands.Delete().ButtonType(ButtonType); }).Width(90).Visible(???); Thanks!

  • How to make an NSOutlineView indent multiple columns?

    - by Rinzwind
    What would be the easiest or recommended way for making an NSOutlineView indent multiple columns? By default, it only indents the outline column; and as far as I know there is no built-in support for making it indent other columns. I have an NSOutlineView which shows a comparison between two sets of hierarchical data. For visual appeal, if some item in the outline column is indented, I'd like to indent the item on the same row in another column by the same indentation amount. (There's also a third column which shows the result of comparing the two items, this column should never be indented.) Can this only be achieved by subclassing NSOutlineView? And what would need to be overridden in the subclass? Or is there an easier way to get it to indent multiple columns?

  • how to hide table columns in jQuery?

    - by understack
    I've a table with lots of columns. I want to give users the option to select columns to be shown in table. These options would be checkboxes along with the column names. So how can I hide/unhide table columns based on checkboxes? Would hiding (using .hide()) each td in each row work? May be I can assign checkbox value to the location of column in table. So first checkbox means first column and so on. And then recursively hide that 'numbered' td in each row. Would that work?

  • BULK INSERT with inconsitant number of columns

    - by aceinthehole
    I am trying to load a large amount data in SQL server from a flat file using BULK INSERT. However, my file has varying number of column, for instance the first row contains 14 and the second contains 4. That is OK, I just want to make a table with the max number of columns and load the file into it with nulls for the missing columns. I can play with it from that point. But it seems that SQL Server when reaching the end of the line and having more columns to fill for that same row in the destination table, just moves on to the next line and attempts to put the data on that line to the wrong column of the table. Is there a way to get the behavior that I am looking for? Is there a table hint that I can use the specify this? Has anyone run into this before? Here is the code BULK INSERT #t FROM '<path to file>' WITH ( DATAFILETYPE = 'char', KEEPNULLS, FIELDTERMINATOR = '#' )

  • List of all index & index columns in SQL Server DB

    - by Anton Gogolev
    How do I get a list of all index & index columns in SQL Server 2005+? The closest I could get is: select s.name, t.name, i.name, c.name from sys.tables t inner join sys.schemas s on t.schema_id = s.schema_id inner join sys.indexes i on i.object_id = t.object_id inner join sys.index_columns ic on ic.object_id = t.object_id inner join sys.columns c on c.object_id = t.object_id and ic.column_id = c.column_id where i.index_id > 0 and i.type in (1, 2) -- clustered & nonclustered only and i.is_primary_key = 0 -- do not include PK indexes and i.is_unique_constraint = 0 -- do not include UQ and i.is_disabled = 0 and i.is_hypothetical = 0 and ic.key_ordinal > 0 order by ic.key_ordinal which is not exactly what I want. What I want is to list all user-defined indexes (which means no indexes which support unique constraints & primary keys) with all columns (ordered by how do they apper in index definition) plus as much metadata as possible.

  • Fluid Columns with matching height and background image

    - by JamesArmes
    I'm working on a new layout for my site that uses a header, footer and two column center region. The two columns consist of the main content area which is fluid height and width and a right sidebar which is fluid height and fixed width. I have done similar layouts before, but this one depends on using two different background images (one for the sidebar and one for the content area). Is there any way to implement this, using proper HTML & CSS, so that the background images of the two columns are always the same height, regardless of which columns content is longer? I've tried using JavaScript to simulate this, but it doesn't work so well if there are images in the content area. I would really prefer not to use this method any way. Any help is greatly appreciated. I have setup a staging environment at http://staging.jamesarmes.net/jimmyssandbox to provide an example. This environment is not my finished product, but I want to get the containers under control before I move any further
