• File management

  - by user343934

  I am working on python and biopython right now. I have a file upload form and whatever file is uploaded suppose(abc.fasta) then i want to pass same name in execute (abc.fasta) function parameter and display function parameter (abc.aln). Right now i am changing file name manually, but i want to have it automatically. Workflow goes like this. ----If submit is not true then display only header and form part --- if submit is true then call execute() and get file name from form input --- Then display the save file result in the same page. File name is same as input. My raw code is here -- http://pastebin.com/FPUgZSSe Any suggestions, changes and algorithm is appreciated Thanks

• unknown column in where clause

  - by ranzy

  $result = mysql_query("SELECT * FROM Volunteers WHERE Volunteers.eventID = " . $var); $sql = mysql_query("SELECT * FROM Members WHERE Members.pid = " . $temp); I am also doing or die(mysql_error()) at the end of both statements if that matter. My problem is that the first statement executes perfectly but in that table I store an attribute called pid. So the second statement is supposed to take that and return the row where it equals that pid so I can get the name. I get an error that says unknown column in 'a2' in 'where clause' where a2 the pid attribute returned from the first statement. Thanks for any help!

• Push a bookmark to a user's home screen in Android

  - by JohnTheBarber

  Android 2.1 (not sure how much that matters) My test hardware is a Motorola Droid (not sure how much that matters either) I want to push a bookmark/internet-shortcut to a user's home screen as a result of them clicking on a link - via their browser of choice. I know they can usually set the bookmark themselves and then choose to put it on their home screen. But I'd like to provide a link like "Put a shortcut to this page on your home screen" that takes care of everything kind of in the background/underneath. Is this even possible? What parts of the framework would I need access to to make it happen?

• How to append text to a text file in WinAPI?

  - by Bruce

  Hi guys, Ive got an annoying problem, I cant append any text to the text file. Every time I open it for writing, I overwrite the data. I tried to move the file pointer to the end of the file, but no result (no writing to the file at all). Here is the code: INVOKE CreateFile, offset filePath, GENERIC_WRITE, FILE_SHARE_WRITE, 0, OPEN_ALWAYS,FILE_ATTRIBUTE_NORMAL,0 mov hFile, eax mov edx, 10 INVOKE SetFilePointer, hFile, 0, 0, FILE_END INVOKE WriteFile, hFile, offset buffer, edx, ADDR SizeReadWrite, NULL INVOKE CloseHandle, hFile Any ideas? Thank you in advance!

• [BST] Deletion procedure

  - by Metz

  Hi all. Consider the deletion procedure on a BST, when the node to delete has two children. Let's say i always replace it with the node holding the minimum key in its right subtree. The question is: is this procedure commutative? That is, deleting x and then y has the same result than deleting first y and then x? I think the answer is no, but i can't find a counterexample, nor figure out any valid reasoning. Thank you. EDIT: Maybe i've got to be clearer. Consider the transplant(node x, node y) procedure: it replace x with y (and its subtree). So, if i want to delete a node (say x) which has two children i replace it with the node holding the minimum key in its right subtree: y = minimum(x.right) transplant(y, y.right) // extracts the minimum (it doesn't have left child) y.right = x.right y.left = x.left transplant(x,y) The question was how to prove the procedure above is not commutative.

• Using a singleton database class in functions and multiple scripts(PHP) - best use methods

  - by dscher

  I have a singleton db connection which I get with: $dbConnect = myDatabase::getInstance(); which is easy enough. My question is what is the least rhetorical and legitimate way of using this connection in functions and classes? It seems silly to have to declare the variable global, pass it into every single function, and/or recreate this variable within every function. Is there another answer for this? Obviously I'm a noob and I can work my way around this problem 10 different ways, none of which is really attractive to me. It would be a lot easier if I could have that $dbConnect variable accessible in any function without needing to declare it global or pass it in. I do know I can add the variable to the $_SERVER array...is there something wrong with doing this? It seems somewhat inappropriate to me. Another quick question: Is it bad practice to do this: $result = myDatabase::getInstance()-query($query); from directly within a function?

• Passing Data from Usercontrol to controller

  - by nitinkhanna

  Hi, I am new to MVC, and trying something and got stuck somewhere in between. I have a user control there I have three textbox html type(ID, Lastname, firstname) and a submit buttom. I set the button like <input type="button" value="Search" onclick="location.href='<%= Url.Action("action", "controller") %>'" /> I have called this usercontrol on some view through <%= Html.Partial("ucName") %> Now on pressing that button(on user control) I need to pass the data from these textboxes to controller again to some specific action(Http Post action). By using this data I want to do some database interaction and storing the result in a dataset and pass this data set to same view again to show up in some Grid. I know the first part in conventional Asp.net can be done by raising the event through delegate but don't know how to do that in MVC.

• Websites' color scheme generators - what to do with them in real life?

  - by Marco Demaio

  On the web there are plenty of color scheme/palette generator tools and color palettes galleries. All of these tools/gelleries show many 3 to 5 colors palette as final result. Some of these tools: http://kuler.adobe.com, http://www.colorexplorer.com I know my question might sound ridicolous to someone who is involved in web dedign, but I don't understand what to do with these color palette. I mean, if I have to create a website, how am I supposed to apply this color palette to the website. Which color goes as foreground text, which one as background, which one for the links, which one for the page titles and so on? What are these color palette generators useful for then?! Thanks!

• SQL for total count and count within that where condition is true

  - by twmulloy

  Hello, I have a single user table and I'm trying to come up with a query that returns the total count of all users grouped by date along with the total count of users grouped by date who are of a specific client. Here is what I have thus far, where there's the total count of users grouped by date, but can't seem to figure out how to get the count of those users where user.client_id = x SELECT user.created, COUNT(user.id) AS overall_count FROM user GROUP BY DATE(user.created) trying for a row result like this: [created] => 2010-05-15 19:59:30 [overall_count] => 10 [client_count] => (some fraction of overall count, the number of users where user.client_id = x grouped by date)

• Testing file uploading and downloading speed using FTP

  - by Toman

  Hi all, I am working in a desktop application using java. In my application i have to perform a speed test which will show the file uploading and downloading speed. For uploading test i am uploading a small test file to a FTP server and based on time taken i am calculating the file upload speed. similarly i am downloading a test file form server and calculating download speed. But result i am getting doesn't match with actual FTP file uploading and downloading speed.it seems that the establishing connection to FTP server is increasing the time, hence the resultant speed i am calculating is less. Could you suggest any link or some way to get nearest uploading and downloading speed. i thanks to all your valuable suggestion.

• How does R treat positional arguments

  - by inspectorG4dget

  I'm a python guy and very new to R (so far, all I've done is copy-paste code and screen-shot the resulting, graph). I would now like to actually learn the language so that I can draw useful plots (right now, I am trying to plot this). In attempting my first plot, I came across this function call: sets_options("universe", seq(from = 0, to = 25, by = 0.1)) Now, I would like to know if I can achieve the same result by calling sets_options("universe", seq(0, 25, 0.1)) The help page for seq doesn't speak to this specifically (or I'm not reading it correctly), so I was hoping someone could shed some light on how R handles positional arguments I tried calling the function that way in R and it worked (no syntax errors, etc), but I don't know how to test the output of that function, so I'm forced to ask here

• delphi "Invalid use of keyword" in TQuery

  - by Baldric

  I'm trying to populate a TDBGrid with the results of the following TQuery against the file Journal.db: select * from Journal where Journal.where = "RainPump" I've tried both Journal."Where" and Journal.[Where] to no avail. I've also tried: select Journal.[Where] as "Location" - with the same result. Journal.db is a file created by a third party and I am unable to change the field names. The problem is that the field I'm interested in is called 'where' and understandably causes the above error. How do I reference this field without causing the BDE (presumably) to explode?

• In SQL / MySQL, what is the difference between "On" and "Where" in a join statement?

  - by Jian Lin

  The following statements give the same result (one is using "on", and the other using "where"): mysql> select * from gifts INNER JOIN sentGifts on gifts.giftID = sentGifts.giftID; mysql> select * from gifts INNER JOIN sentGifts where gifts.giftID = sentGifts.giftID; I can only see in a case of a Left Outer Join finding the "unmatched" cases: (to find out the gifts that were never sent by anybody) mysql> select name from gifts LEFT OUTER JOIN sentgifts on gifts.giftID = sentgifts.giftID where sentgifts.giftID IS NULL; In this case, it is first using "on", and then "where". Does the "on" first do the matching, and then "where" does the "secondary" filtering? Or is there a more general rule of using "on" versus "where"? Thanks.

• How to create a "dependency graph" for IT assets

  - by p.marino

  One of my customers is trying to create an interactive "matrix" of interdependencies for the various applications used in their company (it's a travel&leisure company with around 2500 employees). The idea (still at the prototype stage) is to create a sort of Map, based on Visio or similar tool, which traces the communication and interdependencies between all the IT assets in the company, so that when someone asks for a change they can get an overview of the impacts. This was mentioned in a casual setting and it will not be my responsability to directly work on this, but I did contribute the little I know already in terms of vaguely related methodologies (Zachman Framework). I'd like to hear from the people in here if they know of methodologies, or tools, that may help this kind of effort, and if they have any specific experience to contribute. I'll digest the answers and send the result back to my customer, hoping this may be of some help with their task (which I consider a bit visionary and prone to all the pitfalls of any documentation project, but still well worth pursuing).

• Convert long number as string in the serialization

  - by Bruno

  I have a custom made class that use a long as ID. However, when I call my action using ajax, my ID is truncated and it loses the last 2 numbers because javascript loses precision when dealing with large numbers. My solution would be to give a string to my javascript, but the ID have to stay as a long on the server side. Is there a way to serialize the property as a string? I'm looking for some kind of attribute. Controller public class CustomersController : ApiController { public IEnumerable<CustomerEntity> Get() { yield return new CustomerEntity() { ID = 1306270928525862486, Name = "Test" }; } } Model public class CustomerEntity { public long ID { get; set; } public string Name { get; set; } } JSON Result [{"Name":"Test","ID":1306270928525862400}]

• Crystal Reports, alignment when printing

  - by andySF

  Hello, i have a report with 2 objects. a text object from left to right and a database field on top of this object. When I load the report in viewer(or print from viewer) it looks OK but when I print the report programmatically with ReportDocument.PrintToPrinter() the database field moves to to the left and as a result it print on the text object. Concatenate the text and database field is not an option. The margins are the same in viewer and before to print programmatically. in viewer: http://promagic.hopto.org/screens/screen_2010-5-13_10_24_7-531.png programmatically: http://promagic.hopto.org/screens/screen_2010-5-13_10_25_55-187.png (the bold text is from db) Can anyone help me?

• how to optimize an oracle query that has to_char in where clause for date

  - by panorama12

  I have a table that contains about 49403459 records. I want to query the table on a date range. say 04/10/2010 to 04/10/2010. However, the dates are stored in the table as format 10-APR-10 10.15.06.000000 AM (time stamp). As a result. When I do: SELECT bunch,of,stuff,create_date FROM myTable WHERE TO_CHAR (create_date,'MM/DD/YYYY)' >= '04/10/2010' AND TO_CHAR (create_date, 'MM/DD/YYYY' <= '04/10/2010' I get 529 rows but in 255.59 seconds! which is because I guess I am doing to_char on EACH record. However, When I do SELECT bunch,of,stuff,create_date FROM myTable WHERE create_date >= to_date('04/10/2010','MM/DD/YYYY') AND create_date <= to_date('04/10/2010','MM/DD/YYYY') then I get 0 results in 0.14 seconds. How can I make this query fast and still get valid (529) results?? At this point I can not change indexes. Right now I think index is created on create_date column

• Simplest way of creating java next/previous buttons

  - by Holly

  I know that when creating buttons, like next and previous, that the code can be somewhat long to get those buttons to function. My professor gave us this example to create the next button: private void jbtnNext_Click() { JOptionPane.showMessageDialog(null, "Next" ,"Button Pressed", JOptionPane.INFORMATION_MESSAGE); try { if (rset.next()) { fillTextFields(false); }else{ //Display result in a dialog box JOptionPane.showMessageDialog(null, "Not found"); } } catch (SQLException ex) { ex.printStackTrace(); } } Though, I do not really understand how that short and simple if statement is what makes the next button function. I see that the fillTextFields(false) uses a boolean value and that you need to initialize that boolean value in the beginning of the code I believe. I had put private fillTextFields boolean = false; but this does not seem to be right... I'm just hoping someone could explain it better. Thanks :)

• SSRS Column Grouping with specific order

  - by AmiT

  Hi Experts, Is it possible to change order of records/groups in a result-set from a query using Group By? =I have a query: SELECT Category, Subcategory, ProductName, CreatedDate, Sales From TableCategory tc INNER JOIN TableSubCategory ts ON tc.col1 = ts.col2 INNER JOIN TableProductName tp ON ts.col2 = tp.col3 Group By Category, SubCategory, ProductName, CreatedDate, Sales = Now, I am creating a ssrs report where Category is Primary row group, then SubCategory is its child row group. Then ProductName is a Primary Column Group. It works perfect, But it shows the ProductNames in alphabatic order. I want it to show the ProductNames in custom order(defined by me).Like, ProductNo5 in 3rd column, ProductNo8 in 4th column, ProductNo1 in 5th column ... and so on!

• Mysql: how to generate count table by PATTERN / LIKE statement ? very tricky

  - by Abdulrahman Al-Qabandi

  to simplify, I got a database of registered users, I want to count how many emails there are for each email domain name (note I do not know all domain names) for example, Users table- id | email ------------------ 1 | [email protected] 2 | [email protected]<--unknown to me 3 | [email protected]<--unknown to me 4 | [email protected] 5 | [email protected]<--unknown to me 6 | [email protected] 7 | [email protected] 8 | [email protected] ( note: I want to count each email without specifying which email exactly ) so the result I want is suffix | count hotmail.com | 3 somesite.aaa | 2 unknownsite.aaa| 1 yahoo.com | 2 again, I stress this, I do not know unknownsite.aaa nor can i mention it in a statement because it is unknown to me, i hope I am clear. So essentially I want to make a statistic of what my website users use as an email host website. but like I said and I will repeat the third time, I do not know every mailhost that exists. I am going to investigate this more, I have a feeling this is something mysql cannot handle.

• ftp : get list of files

The code was working when I ran it locally, but on deploying it I started receiving html instead of file name ArrayList fName = new ArrayList(); try { StringBuilder result = new StringBuilder(); //create the directory FtpWebRequest requestDir = (FtpWebRequest)FtpWebRequest.Create(new Uri(directory)); requestDir.Method = WebRequestMethods.Ftp.ListDirectory; requestDir.Credentials = new NetworkCredential(FTP_USER_NAME, FTP_PASSWORD); requestDir.UsePassive = true; requestDir.UseBinary = true; requestDir.KeepAlive = false; requestDir.Proxy = null; FtpWebResponse response = (FtpWebResponse)requestDir.GetResponse(); Stream ftpStream = response.GetResponseStream(); StreamReader reader = new StreamReader(ftpStream, Encoding.ASCII); while (!reader.EndOfStream) { fName.Add(reader.ReadLine().ToString()); } response.Close(); ftpStream.Close(); reader.Close();

• Bind jQuery UI autocomplete using .live()

  - by seth.vargo

  I've searched everywhere, but I can't seem to find any help... I have some textboxes that are created dynamically via JS, so I need to bind all of their classes to an autocomplete. As a result, I need to use the new .live() option. As an example, to bind all items with a class of .foo now and future created: $('.foo').live('click', function(){ alert('clicked'); }); It takes (and behaves) the same as .bind(). However, I want to bind an autocomplete... This doesn't work: $('.foo').live('autocomplete', function(event, ui){ source: 'url.php' // (surpressed other arguments) }); How can I use .live() to bind autocomplete? UPDATE Figured it out with Framer: $(function(){ $('.search').live('keyup.autocomplete', function(){ $(this).autocomplete({ source : 'url.php' }); }); });

• Python win32api not moving mouse cursor in VirtualBox

  - by wes

  I'm trying to use this Python code: import math for i in xrange(500): x = 500 + math.sin(math.pi * i / 100) * 500 y = 500 + math.cos(i) * 100 x, y = int(x), int(y) win32api.SetCursorPos((x, y)) time.sleep(.01) taken from here to move the mouse cursor in an XP VirtualBox. The mouse icon will flicker to the appropriate graphic (when it hits the edge of a window it turns into the <- resize image, for instance), but it doesn't actually move the visible cursor. I can move the mouse around while the code is running. Same result using the ctypes example in the above link. It works fine in the Win7 host. I have Guest Additions installed, if that matters.
