• interesting vba/access question: color rectangles according to data

  - by every_answer_gets_a_point

  i have a datasheet that looks like this: ID name_ 1 2 3 4 1 name1 x 0 0 0 2 name2 0 x 0 0 3 name3 0 0 x 0 4 name4 0 0 0 x i have rectangles on a report that correspond to this datasheet. when the report opens, i need the rectangles to be colored RED according to the data. for example where name1 and there is an x in the 1 column, i need the specific rectangle corresponding to this (name1, 1) to be colored red. here is the result that i will need: x x x x (where x is a rectangle that is RED) perhaps the best place to place this code would be in ON LOAD event of the report, but i am not sure exactly. can you please suggest to me some code that would turn the specified rectangles RED according to the data?

• Window opened from DataGrid is placed in background

  - by 0xddr

  One column in DataGrid looks like that: <DataTemplate> <StackPanel> <Image MouseDown="OpenWindow" /> <Image MouseDown="func2"/> </StackPanel> </DataTemplate> In OpenWindow window is opened: it starts opening in foreground (in front of the window with DataGrid), but when creating UI ends it is placed behind window with DataGrid, which is not expected behavior. When I changed Image to Button and MouseDown to Click everything works as it should (opened window is placed in front of the one with DataGrid).

• Extreamely fast way to clone the values of an array into a second array?

  - by George

  I am currently working on an application that is responsible for calculating random permutations of a multidemensional array. Currently the bulk of the time in the application is spent copying the array in each iteration (1 million iterations total). On my current system, the entire process takes 50 seconds to complete, 39 of those seconds spent cloning the array. My array cloning routine is the following: public static int[][] CopyArray(this int[][] source) { int[][] destination = new int[source.Length][]; // For each Row for (int y = 0; y < source.Length; y++) { // Initialize Array destination[y] = new int[source[y].Length]; // For each Column for (int x = 0; x < destination[y].Length; x++) { destination[y][x] = source[y][x]; } } return destination; } Is there any way, safe or unsafe, to achieve the same effect as above, much faster?

• MySQL ORDER BY returns things in (apparently) random order !?

  - by Luke H

  The following query: SELECT DISTINCT ClassName FROM SiteTree ORDER BY ClassName is returning things in no apparent order! I get the same result whether I quote column/table names, or use DISTINCT or not, or add ASC or DESC. I assumed the indexes might be broken, or something like this, so tried dropping and recreating. Also tried REPAIR TABLE and CHECK TABLE. The table collation is set to latin1_swedish_ci. All the textual columns are set to use UTF-8 and collation is set to utf8_general_ci What could be causing this?

• No difference between nullable:true and nullable:false in Grails 1.3.6?

  - by knorv

  The following domain model definition .. class Test { String a String b static mapping = { version(false) table("test_table") a(nullable: false) b(nullable: true) } } .. yields the following MySQL schema .. CREATE TABLE test_table ( id bigint(20) NOT NULL AUTO_INCREMENT, a varchar(255) NOT NULL, b varchar(255) NOT NULL, PRIMARY KEY (id) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; Please note that a and b get identical MySQL column definitions despite the fact a is defined as non-nullable and b is nullable in the GORM mappings. What am I doing wrong? I'm running Grails 1.3.6.

• Categorized SharePoint Discussion - default category to parents category on reply.

  - by Greg Ogle

  I have a Discussion Board in a SharePoint site which has an additional column named Category. When a new discussion is created, it prompts for Category, and of course this is by design. The problem is that when the discussion is replied to, it prompts for the category again. How can I separate the reply functionality so that the Category is not prompted and the Category is set to that of the discussion under which it resides? I attempted to edit a copy of NewForm.aspx in SharePoint Designer, but you can only edit which WebPart it is using, not which fields are displayed.

• Is there a way to use XDocument in the Application Settings?

  - by Shimmy

  I have to store a complex type in the application settings. I thought that storing it as XML would work best. The problem is I don't know how store XML. I prefer to store it as a managed XML rather than using just a string of raw XML having to parse it on each access. I managed to set the Type column of the setting to XDocument, but I was unable to set its value. Is there a way to use XDocument or XML in application settings?

• Standard procedure for confirming email for a web app

  - by Woho87

  Hi! I have created a web app that is almost finished. I need it to confirm new emails. I just want to know if the these are the right procedures for that, because I'm not familiar with this. I create a new table called "confirmEmails" with only one column with uniqueId. A unique Id is created with PHP: uniqueid() which is created directly after a user hit the submit button. And the php script stores it on the table. An email is sent together with a link www.domain.com/confirmEmail.php?uniqueId=kushfpuhrufhufhfhuhfheriufhehu. I have an another php script called confirmEmail.php that gets the value if uniqueId through the link with $_GET['uniqueId'];(maybe I shall use post instead her). And now it stores the new email in table called user Is it right procedures? Pls give me some feedback!

• Python Continue Loop

  - by Rob B.

  I am using the following code from this tutorial (http://jeriwieringa.com/blog/2012/11/04/beautiful-soup-tutorial-part-1/). from bs4 import BeautifulSoup soup = BeautifulSoup (open("43rd-congress.html")) final_link = soup.p.a final_link.decompose() trs = soup.find_all('tr') for tr in trs: for link in tr.find_all('a'): fulllink = link.get ('href') print fulllink #print in terminal to verify results tds = tr.find_all("td") try: #we are using "try" because the table is not well formatted. This allows the program to continue after encountering an error. names = str(tds[0].get_text()) # This structure isolate the item by its column in the table and converts it into a string. years = str(tds[1].get_text()) positions = str(tds[2].get_text()) parties = str(tds[3].get_text()) states = str(tds[4].get_text()) congress = tds[5].get_text() except: print "bad tr string" continue #This tells the computer to move on to the next item after it encounters an error print names, years, positions, parties, states, congress However, I get an error saying that 'continue' is not properly in the loop on line 27. I am using notepad++ and windows powershell. How do I make this code work?

• Is there a way to use a dictionary or xml in the Application Settings?

  - by Shimmy

  I have to store a complex type in the application settings. I thought that storing it as XML would work best. The problem is I don't know how store XML. I prefer to store it as a managed XML rather than using just a string of raw XML having to parse it on each access. I managed to set the Type column of the setting to XDocument, but I was unable to set its value. Is there a way to use XDocument or XML in application settings? Update I found a way, simply by editing the .settings file with the xml editor. I changed it to a custom serializable dictionary, but I get the following error when I try to access the setting-property (I set it to a serialized representation of the default value). The property 'Setting' could not be created from it's default value. Error message: There is an error in XML document (1, 41). Any ideas will be appreciated.

• Why is selecting specified columns, and all, wrong in Oracle SQL?

  - by TomatoSandwich

  Say I have a select statement that goes.. select * from animals That gives a a query result of all the columns in the table. Now, if the 42nd column of the table animals is is_parent, and I want to return that in my results, just after gender, so I can see it more easily. But I also want all the other columns. select is_parent, * from animals This returns ORA-00936: missing expression. The same statement will work fine in Sybase, and I know that you need to add a table alias to the animals table to get it to work ( select is_parent, a.* from animals ani), but why must Oracle need a table alias to be able to work out the select?

• Serialized object in intent returning as String

  - by B_

  In my application, I am trying to pass a serializable object through an intent to another activity. The intent is not entirely created by me, it is created and passed through a search suggestion. In the content provider for the search suggestion, the object is created and placed in the SUGGEST_COLUMN_INTENT_EXTRA_DATA column of the MatrixCursor. However, when in the receiving activity I call getIntent().getSerializableExtra(SearchManager.EXTRA_DATA_KEY), the returned object is of type String and I cannot cast it into the original object class. I tried making a parcelable wrapper for my object that calls out.writeSerializable(...) and use that instead but the same thing happened. The string that is returned is like a generic Object toString(), i.e. com.foo.yak.MyAwesomeClass@4350058, so I'm assuming that toString() is being called somewhere where I have no control. Hopefully I'm just missing something simple. Thanks for the help!

• SQL tables using VARCHAR with UTF8 (with respect to multi byte character length)

  - by Elius

  Like in Oracle VARCHAR( 60 CHAR ) I would like to specify a varchar field with variable length depending on the inserted characters. for example: create table X (text varchar(3)) insert into X (text) VALUES ('äöü') Should be possible (with UTF8 as the default charset of the database). On DB2 I got this Error: DB2 SQL Error: SQLCODE=-302, SQLSTATE=22001 (Character data, right truncation occurred; for example, an update or insert value is a string that is too long for the column, or a datetime value cannot be assigned to a host variable, because it is too small.) I'm looking for solutions for DB2, MsSql, MySql, Hypersonic.

• Insert consecutive numbers

  - by Markus

  Hi. I have a table A (Acons, A1, A2, A3) in which I should insert information from another table B with columns (B1, B2, B3). The Acons is a column in which should contain some consecutive numbers (it is not an identity and I cannot make it identity). I know xmin - starting the from number the sequence has to be computed. How can I insert the rows into the table A, using a single Insert statement? I tried like the following, but it didn't work: DECLARE @i AS INT; SET @i = xmin; INSERT INTO A(Acons, A1, A2, A3) SELECT @i = (Bcons = (@i + 1)), B1, B2, B3 FROM B Unfortunatelly, the above solution does not work;

• allow only distinct values in ComboBox

  - by Ravinder Gangadher

  In my project, I am trying to populate ComboBox from DataSet. I succeeded in populating but the values inside the ComboBox are not distinct (Because it just showing the values present in DataSet). I cant bind the ComboBox to DataSet because I am adding "Select" text at first of populating the values. Here is my code. ComboBox --> cmb DataSet --> ds DataSet Column Name --> value(string) cmb.Items.Clear(); cmb.Items.Add("Select"); for (int intCount = 0; intCount < ds.Tables[0].Rows.Count; intCount++) { cmb.Items.Add(ds.Tables[0].Rows[intCount][value].ToString()); } cmb.SelectedIndex = 0; My question is how to allow distinct values (or restrict duplicate values) inside the ComboBox.

• How to import datarow from one dataset to another?

  - by Disciple

  Hi, I want to copy the row to the new dataset if the previous value in second column isn't the same as the current one (i.e this dataset should have rows with unique values): DataTable tbl = new DataTable(); DataTable tmpTable = ds.Tables[0]; for( var rowIndex = 0; rowIndex < ds.Tables[0].Rows.Count; rowIndex++ ) { object value = null; foreach (DataRow x in tbl.Rows) { if (ds.Tables[0].Rows[rowIndex][1] == x[1]) { value = ds.Tables[0].Rows[rowIndex][1]; break; } } // value already exists if (value == null) { tbl.ImportRow(ds.Tables[0].Rows[rowIndex]); } } How to do this correctly? Maybe one loop instead 2?

• Return cell reference as result of if statement with vlookups.

  - by EMJ

  I have two sets of data in excel. One contains a set of data which represents the initial step of a process. The other set of data represents the additional steps which take place after the first step is completed. Each of the data records in the "additional step data" has an id in a column. I need to find the identifying codes of the "additional step data" which correspond with the initial step data records. The problem is that I have to match the data in 4 columns between the two data sets and return the id of the "additional step data". I started by doing a combination of an if and vlookup functions, but I got stuck when I tried to figure out how to get the if statement to reference the id of the matching "additional step data". Basically I am trying to avoid having to search by manually filtering between two sets of data and finding corresponding records. Does anyone have any idea about how to do this?

• Dynamic SQL queries in code possible?

  - by SeanD

  Instead of hard coding sql queries like Select * from users where user_id =220202 can these be made dynamic like Select * from $users where $user_id = $input. Reason i ask is when changes are needed to table/column names i can just update it in one place and don't have to ask developers to go line by line to find all references to update. It is very time consuming. And I do not like the idea of exposing database stuff in the code. My major concern is load time. Like with dynamic pages, the database has to fetch the page content, same way if queries are dynamic first system has to lookup the references then execute the queries, so does it impact load times? I am using codeignitor PHP. If it it possible then the next question is where to store all the references? In the app, in a file, in the DB, and how?

• How to insert a value based on lookup from another table [SQL]?

  - by Shaitan00

  I need to find a way to do an INSERT INTO table A but one of the values is something that comes from a lookup on table B, allow me to illustrate. I have the 2 following tables: Table A: A1: String A2: Integer value coming from table B A3: More Data Table B: B1: String B2: Integer Value Example row of A: {"Value", 101, MoreData} Example row of B: {"English", 101} Now, I know I need to INSERT the following into A {"Value2", "English", MoreData} but obviously that won't work because it is expecting an Integer in the second column not the word "English", so I need to do a lookup in Table B first. Something like this: INSERT INTO tableA (A1, A2, A3) VALUES ("Value2", SELECT B2 FROM tableB where B1="English", MoreData); Obviously this doesn't work as-is ... Any suggestions?

• Fetch last item in a category that fits specific criteria

  - by Franz

  Let's assume I have a database with two tables: categories and articles. Every article belongs to a category. Now, let's assume I want to fetch the latest article of each category that fits a specific criteria (read: the article does). If it weren't for that extra criteria, I could just add a column called last_article_id or something similar to the categories table - even though that wouldn't be properly normalized. How can I do this though? I assume there's something using GROUP BY and HAVING?

• Checking sqlite datetime NULL with RoR

  - by Paul N

  RoR/SQL newbie here. My datetime column 'deleted_at' are all uninitialized. Running this query returns an error: SELECT * FROM variants v ON v.id = ovv0.variant_id INNER JOIN option_values_variants ovv1 ON v.id = ovv1.variant_id INNER JOIN option_values_variants ovv2 ON v.id = ovv2.variant_id INNER JOIN option_values_variants ovv3 ON v.id = ovv3.variant_id INNER JOIN option_values_variants ovv4 ON v.id = ovv4.variant_id WHERE v.deleted_at = NULL AND v.product_id = 1060500595 However, if I set my datetime values to 0, and set my query to v.deleted_at = 0, the correct variant is returned to me. How do I check for uninitialized/NULL datetimes?
