• SQL update fields of one table from fields of another one.

  - by Nir

  I'm having two tables: A [ID, column1, column2, column3] B [ID, column1, column2, column3, column4] A table will always be subset of B table (meaning all columns of A are also in B). I want to update a record with a specific ID in B with their data from A for all columns of A. This ID exists both in A and B. Is there an UPDATE syntax or any other way to do that without specifying the column names, just saying "set all columns of A"? I'm using postgresql, so a specific non-standard command is also accepted (however, not preferred). Thanks.

• create_function with default parameter values?

  - by SoLoGHoST

  Ok, I'm looking into using create_function for what I need to do, and I don't see a way to define default parameter values with it. Is this possible? If so, what would be the best approach for inputting the params into the create_function function in php? Perhaps using addslashes? Well, for example, I have a function like so: function testing($param1 = 'blah', $param2 = array()) { if($param1 == 'blah') return $param1 else { $notblah = ''; if (count($param2) >= 1) { foreach($param2 as $param) $notblah .= $param; return $notblah; } else return 'empty'; } } Ok, so how would I use create_function to do the same thing, adding the parameters and their default values? The thing is, the parameters are coming from a TEXT file, as well as the function itself. So, wondering on the best approach for this using create_function and how exactly the string should be parsed. Thanks :)

• Datetime problem in VB 2005

  - by haythamhamdy

  I am using VB2005 and SQL SERVER 2000. PVAR_SQL_STR = "INSERT INTO GLR_US_PERIOD (ORG5_CODE,PERIOD_YEAR,PERIOD_CODE,PERIOD_NO,FROM_DATE,TO_DATE,INSERT_USER,INSERT_DATE) VALUES " _ & "('" & PVAR_COMPANY_CODE & "' ,'" & TextBox1.Text & "','" & Serial1.Text & "'," & TextBox2.Text & ", '" + DateTimePicker1.Value.ToString("D") + "' ,'" + DateTimePicker2.Value.ToString("D") + "','" & PVAR_USER_CODE & "','" + Now.ToString("F") + "')" Syntax error converting datetime from character string because of this part only: Now.ToString("F") Why, I do not know but when I change into Now.ToString("D") it works well but it saves the date only. I want to insert date and time.

• Make Excel Defined Names within a worksheet to be global

  - by idazuwaika

  Hi, I wrote Powershell script to copy a worksheet from a workbook A to another workbook B. The worksheet contains define names for ranges within that sheet. Originally, the defined names are global in workbook A, ie. can be referenced from any worksheets within workbook A. But now, after copy to worksheet B, the defined names are limited to that worksheet only. How to I programmatically (via Powershell script preferably) make all those named range global i.e. can be referenced from all worksheets within workbook B. Some codes for clarity. #Script to update SOP from 5.1 to 5.2 $missing = [System.Type]::missing #Open files $excel = New-Object -Com Excel.Application $excel.Visible = $False $excel.DisplayAlerts = $False $newTemplate = "C:\WorkbookA.xls" $wbTemplate = $excel.Workbooks.Open($newTemplate) $oldSop = "C:\WorkbookB.xls" $wbOldSop = $excel.Workbooks.Open($oldSop) #Delete 'DATA' worksheet from old file $wsOldData = $wbOldSop.Worksheets.Item("DATA") $wsOldData.Delete() #Copy new 'DATA' worksheet to old file $wbTemplate.Worksheets.Item("DATA").Copy($missing,$wbOldSop.Worksheets.Item("STATUS")) #Save $wbOldSop.Save() $wbOldSop.Close() #Quit Excel $excel.Quit()

• interfacing: simplified

  - by code wombat

  i've been doing some research on interfaces and a simple layman's explanation for what it truly is. For some reason people love using overly complex explanations and jargon to explain truly simple concepts (guess it makes them feel big) and i have a gut feeling it's the same in this case. so from what i could grasp, it seems like interfaces are nothing more than a way to reserve method names, their return type if any, and the type and amount of arguments they accept. so when a class implements an interface (or interfaces) it is forced to define the body of each method from the interface(s). Am i on the nose with this one or do i need to keep digging? p.s. i know javascript doesn't have support for interfaces, but i still need to understand the concept because there are quite a few places where it's shown how to emulate to an extent.

• Applying a function with multiple inputs using Map? (Haskell)

  - by Schroedinger

  G'day guys, Trying currently to finish up a bit of homework I'm working on, and having an issue where I'm trying to apply map across a function that accepts multiple inputs. so in the case I'm using processList f (x:xs) = map accelerateList f xs x xs processList is given a floating value (f) and a List that it sorts into another List Accelerate List takes a floating value (f) a List and a List Object through which it returns another List Object I know my Accelerate List code is correct, but I cannot for the life of me get the syntax for this code working: processList :: Float -> [Object] -> [Object] accelerate f [] = [] accelerate f [x] = [(accelerateForce f x x)] accelerate f (x:xs) = map accelerateList f xs x xs Any ideas? I've been scratching my head for about 3 hours now. I know it's something really simple.

• how to load a module within python debugger

  - by MK

  This looks like something simple but I could not find the answer so far - I have just learnt python and need to start learning pdb. In my module I have the usual if __name__ == __main_ trick to execute some code when the module is run as a program. So far I have been running it via python -m mymod arg1 arg2 syntax Now I want to do exactly the same thing from inside pdb. Normally in C, I would just do gdb mybinary followed by run arg1 arg2 But I cannot figure out how to achieve the same thing in pdb. I am sure there has to be a simple way to achieve this but it is taking me too long to search for it.. Thanks for your help!

• Anonymous functions in C#

  - by Maxim Gershkovich

  The following syntax is valid VB.NET code Dim myCollection As New List(Of Stock) myCollection.Add(New Stock(Guid.NewGuid, "Item1")) myCollection.Add(New Stock(Guid.NewGuid, "Item2")) Dim res As List(Of Stock) = myCollection.FindAll(Function(stock As Stock) As Boolean If stock.Description = "Item2" Then Return True End If Return False End Function) How can I accomplish the same thing in C#? I have tried... myCollection.FindAll(bool delegate(Stock stock) { if (blah blah) { } }); But it appears I have somehow structured it incorrectly as I get the following error. "Error 1 Invalid expression term 'bool'"

• Comparing datetimes does not work

  - by Koning Baard XIV

  I'm creating a Rails application which uses MySQL. I have a table in my DB like this: create_table "pastes", :force => true do |t| t.string "title" t.text "body" t.string "syntax" t.boolean "private" t.datetime "expire" t.string "password" t.datetime "created_at" t.datetime "updated_at" end I want to show only the non-expired pastes to people, so I do this: @pastes = Paste.find(:all, :conditions => "expire < '#{Time.now.strftime('%Y-%m-%d %H:%M:%S')}'") However, even that returns ALL pastes. Not just those that are not expired yet. Can anyone help me? Thanks Oh, changing < to > returns no pastes, not even the non-expired ones :(

• Indexes and multi column primary keys

  - by David Jenings

  Went searching and didn't find the answer to this specific noob question. My apologies if I missed it. In a MySQL database I have a table with the following primary key PRIMARY KEY id (invoice, item) In my application I will also frequently be selecting on "item" by itself and less frequently on only "invoice". I'm assuming I would benefit from indexes on these columns. MySQL does not complain when I define the following: INDEX (invoice), INDEX (item), PRIMARY KEY id (invoice, item) But I don't see any evidence (using DESCRIBE -- the only way I know how to look) that separate indexes have been established for these two columns. So the question is, are the columns that make up a primary key automatically indexed individually? Also, is there a better way than DESCRIBE to explore the structure of my table?

• Javascript appending onload to a popup window

  - by Hypnotic Meat

  I'm trying to append an onload event to a popup window in the following manner: var explorerWindow = window.open(PARAMS...); explorerWindow.onload = function() {window.opener.unlockObj(id);} The idea is to make the button that generates the popup window readonly, making it usable again once the popup window has loaded all of its contents. However, the event doesn't seem to be firing at all. I even changed it to the following and got nothing: explorerWindow.onload = function() {alert("bloop");} Is there something terribly wrong with my syntax or am I missing something else entirely? Also, I'm using JQuery if there are any appropriate gems there that will help in this situation. I tried the following with similar results, but I'm not so sure I got the call right: $(explorerWindow).load(function() {alert("bloop");}); Any help is greatly appreciated.

• XNA 2d camera with arbitrary zoom center

  - by blooop

  I have a working 2D camera in XNA with these guts: ms = Mouse.GetState(); msv = new Vector2(ms.X, ms.Y); //screenspace mouse vecor pos = new Vector2(0, 0); //camera center of view zoom_center = cursor; //I would like to be able to define the zoom center in world coords offset = new Vector2(scrnwidth / 2, scrnheight / 2); transmatrix = Matrix.CreateTranslation(-pos.X, -pos.Y, 0) * Matrix.CreateScale(scale, scale, 1) * Matrix.CreateTranslation(offset.X, offset.Y, 0); inverse = Matrix.Invert(transmatrix); cursor = Vector2.Transform(msv, inverse); //the mouse position in world coords I can move the camera position around and change the zoom level (with other code that I have not pasted here for brevity). The camera always zooms around the center of the screen, but I would like to be able to zoom about an arbitrary zoom point (the cursor in this case), like the indie game dyson http://www.youtube.com/watch?v=YiwjjCMqnpg&feature=player_detailpage#t=144s I have tried all the combinations that make sense to me, but am completely stuck.

• Log information inside a JUnit Suite

  - by Alex Marinescu

  I'm currently trying to write inside a log file the total number of failed tests from a JUnite Suite. My testsuite is defined as follows: @RunWith(Suite.class) @SuiteClasses({Class1.class, Class2.class etc.}) public class SimpleTestSuite {} I tried to define a rule which would increase the total number of errors when a test fails, but apparently my rule is never called. @Rule public MethodRule logWatchRule = new TestWatchman() { public void failed(Throwable e, FrameworkMethod method) { errors += 1; } public void succeeded(FrameworkMethod method) { } }; Any ideas on what I should to do to achieve this behaviour?

• boolean type for while loop in bash?

  - by user151841

  I have a cron script on a shared web host that occasionally gets killed. I'd like to make a loop in bash that tries again if it gets killed, because most of the time it will make it. I'm having trouble with the syntax for storing a boolean value :P #!/bin/bash VAR=0; while [ $VAR ]; do if nice -19 mysqldump -uuser -ppassword -h database.hostname.com --skip-opt --all --complete-insert --add-drop-table database_name > ~/file/system/path/filename.sql; then VAR=1; fi done So the script recovers from a killed process okay, but once it's run properly, the new VAR value doesn't kill the while loop. What am I doing wrong?

• Repurpose builtin Word commands - access original command within repurposed function

  - by Aurril

  It is possible to repurpose a Word builtin command in Word 2007 using the customUI.xml file. Example: <customUI xmlns="http://schemas.microsoft.com/office/2009/07/customui"> <commands> <command idMso="Save" onAction="MySave"/> </commands> </customUI> I then have to define a callback function in VBA which is used instead of the builtin function: 'Callback for Save onAction Sub MySave(control As IRibbonControl, ByRef cancelDefault) someFancyPreparationFunction oldSaveFunction ' Where, how? someOtherFancyAfterWorkFunction End Sub And here is my problem, if I want to reuse internal functionality in my repurposed Function, I don't know how to access it. My example is trivial and the save could be easily rebuilt by a call to ThisDocument.save but as I said, it is just an example to show the problem. A call to CommandBars.ExecuteMso('Save') would call my repurposed function and not the original one. Any ideas on how to access the internal functionality after repurposing would be very appreciated!

• How do i plot a vertical axis with variable intervals (Flex Charts or any other)

  - by satish

  How do i plot a vertical axis with variable intervals? on a Flex Chart. I want to plot a data set that has values from 0.1 to 800. When I use a standard Numerical Axis, I have to define a interval. I tried using Log-Axis, but I am not sure how to plot the point values. Looks like something in lines of semi-log axis would be better. A axis with initial values in Numerical, but later shifting gears to a Log-Axis. Any ideas or pointers to implement this in Flex?

• How to force adodb php library to use lowercase field names

  - by spam

  I'm trying to use adodb for db access in my webapp. However my hosting provider has mysql case sensitive, and I have all my fields in lowercase. But when I call getInsertSQL function, I got them in uppercase. Is there a way to force adodb to use lowercase? I tried with define('ADODB_ASSOC_CASE', 0); $ADODB_ASSOC_CASE = 0; But it seems to be ignored as the constant is suppose to be used only with oracle, MSSQL and other DBMS $conn = &ADONewConnection($this->DbType); $conn = PConnect($dbServer,$dbUser, $dbPassword,$database); $tableName = "sample"; $insertSQL = $conn->GetInsertSQL($tableName,$objDB); And I got the SQL statement with the column names in uppercase.

• nicely display file rename history in git log

  - by Jian

  The git command git log --format='%H' --follow -- foo.txt will give you the series of commits that touch foo.txt, following it across renames. I'm wondering if there's a git log command that will also print the corresponding historical file name beside each commit. It would be something like this, where we can interpret '%F' to be the (actually non-existent) placeholder for filename. git log --format='%H %F' --follow -- foo.txt I know this could be accomplished with git log --format='%H' --follow --numstat -- foo.txt but the output is not ideal since it requires some non-trivial parsing; each commit is strewn across multiple lines, and you'll still need to parse the file rename syntax ("bar.txt => foo.txt") to find what you're looking for.

• very weird problem concerning date and time in silverlight + ria services

  - by Patrick LHM

  Hello Friends i'm facing a very weird problem in sliverlight 4 + RIA Services, or maybe it's not weird and i'm just a newbie anyway i hope someone here can help, the problem is the following i've created a function on the server side inside the domain service this function is very simple and has a line in it that adds the server current date and time to the database (it's an HR application and employees should sign in and out thrue it each from it's own pc ) Emp.TimeOut = system.DateTime.now (C# syntax) the weird part is that for some users it always adds 3 hours to the current time(exp if he signes out at 5 it shows 8) and for others it works perfectly. the server and all the stations in the company have exactly the same time settings and the same time zone, and anyway my fucntion is on the server side so it should no be realted to the users time. any ideas why this is happening ? i've bin trying to find out why for days now but with no luck

• Automatic initialization routine in C++ library?

  - by Robert Mason

  If i have a header file foo.h and a source file foo.cpp, and foo.cpp contains something along the lines of: #ifdef WIN32 class asdf { asdf() { startup_code(); } ~asdf() { cleanup_code(); } }; asdf __STARTUP_HANDLE__ #else //unix does not require startup or cleanup code in this case #endif but foo.h does not define class asdf, say i have an application bar.cpp: #include "foo.h" //link in foo.lib, foo.dll, foo.so, etc int main() { //do stuff return 0; } If bar.cpp is compiled on a WIN32 platform, will the asdf() and ~asdf() be called at the appropriate times (before main() and at program exit, respectively) even though class asdf is not defined in foo.h, but is linked in through foo.cpp?

Now i would like to display it in the list via list_display property in admin.ModelAdmin. I have a bunch of things in there, only id is not showing up for any of the rows i have. Everything else works fine. Anyone know anything special i have to do to get id to display? Thanks a lot! Jason

• Delphi JavaDoc Parser

  - by Christian Sciberras

  I need to parse JavaDoc (documentation) comment syntax with Delphi 7. It is well known in the java world as "JavaDoc", but I'm actually doing this for PHP, ie, parsing JavaDoc in some PHP code. Call it PHPDoc if you want to. To see how these comments work, you can see RAD IDEs like NetBeans etc. Example of JavaDoc for addition function: /** * Adds to numbers together. * @param integer $a The first number. * @param integer $b The second number. * @return integer The resulting number. */ function add($a,$b){ return $a+$b; } Please note that the parser need not be full, ie, parsing all of the PHP code. I mean, it's perfectly fine if it accepted the comment text only as input. Cheers, Chris.

Is this possible?
