  • How can I invoke the dialog to set printer options manually?

    - by FromTheMountain
    I'm using WPF and need to let users set some print related options like printer and printer properties (e.g. papertray, landscape/portrait, duplex, etc). I'm aware of the PrintDialog class to get a PrintQueue and PrintTicket object. However I need to create I custom solution and can not show the PrintDialog. I manage to get the available PrintQueue objects and let users select a printer. I'm struggling with the printer properties. My question is: how can I show the dialog in which a user can set the printer properties for the selected PrintQueue (the dialog that is shown when a user clicks on the Properties button in the WPF PrintDialog).

  • How to set result of function as global variable.

    - by George
    I'm sure this is really simple and I'm drawing a giant blank, but how do you set the result of a function as a global variable? Example, I want to set the first "color" in array "colors" as global variable "color" (I know the example doesn't make much practical sense, but it's just to illustrate my question): var color = ""; function selectColor () { var colors = ["blue","red","green","yellow"]; var color = colors[0]; return color; } window.onload = function () { selectColor (); alert(color); }

  • How do I get the resources of a working set?

    - by zvikico
    I know that Eclipse working sets are very flexible and customizable. They are made of elements which implement IAdaptable Which can be anything. However, in many (most) cases, working sets are used to define a set of resources. In case these elements can be seen as resources (e.g. IJavaProject), is there a universal (or formal) way to programatically translate these elements to resources? Eventually, I need to determine whether a given resource is in a working set, so an answer in that direction is acceptable as well.

  • Algorithm: Removing as few elements as possible from a set in order to enforce no subsets.

    - by phimuemue
    Hello, I got a problem which I do not know how to solve: I have a set of sets A = {A_1, A_2, ..., A_n} and I have a set B. The target now is to remove as few elements as possible from B (creating B'), such that, after removing the elements for all 1 <= i <= n, A_i is not a subset of B'. For example, if we have A_1 = {1,2}, A_2 = {1,3,4}, A_3={2,5}, and B={1,2,3,4,5}, we could e.g. remove 1 and 2 from B (that would yield B'={3,4,5}, which is not a superset of one of the A_i). Does anybody know an algorithm for determining the (minimal number of) elements to be removed?

    - by Blankman
    I want all my views to inherit from a baseview data so I can set some shared properties that all my views will need. Can I set some properties in OnExecuting so I don't have to do it for all Actions? I want to then display the string value of the property in all my view pages. If yes, how can I do this? I need to hook into the base view data somehow? so i'll have: public MyViewData : ViewData { } And I need one for generics also?

  • What causes Apache Environment Variable set using mod_rewrite to have "redirect_" appended to name?

    - by trowel
    I am trying to set Apache environment variables (for use in PHP) with the [E=VAR:VAL] flag on RewriteRule rules in an .htaccess file. I have already discovered the variables are accessed in PHP as server variables $_SERVER rather than $_ENV (which makes a certain amount of sense). However, my problem is for some rules the [E=VAR:VAL] flag works as expected and I end up with a variable $_SERVER['VAR'] but for other rules I end with a variable $_SERVER['REDIRECT_VAR'] or $_SERVER['REDIRECT_REDIRECT_VAR'], etc A. What causes an Environment Variable set in Apache using the [E=VAR:VAL] flag to get renamed by having "REDIRECT_" appended to the front of the variable name? B. What can I do to make sure I end up with an Environment Variable with an unchanged name so I can access it in PHP as $SERVER['VAR'] without having to resort to checking for variations of the variable name having one of more instances of "REDIRECT" appended to the front of it?

  • Can you set a form field value with PHP?

    - by dcp3450
    I use the $_GET function to pull a value with php from the url (http:..../index.html?variable=value), basic stuff. However, I need to use that value in my form. Typically, I would set <?php echo 'value="'.$variable.'"' ; ?> or something to that effect. However, I can't use php inside my form using the editor I'm working with. Can I set a value in the form without using PHP in my form? If so, how?

  • How to set a complex custom crontab in google-app-engine (java)?

    - by Shreeni
    I am building an app for which I need to set up cron jobs. What I want to do is to set the specific minutes in a hour where specific crons should run. For instance: Task1 at 1st minute of the hour Task2 on every second minute of the hour Task3 every 2 minute only in the second half of the hour Building this in the standard Unix cron format is reasonably straightforward, but could not figure out how to do it in the Google-App-Engine. The documentation does not list any non-trivial examples. Any suggestions on how to do it? Examples would be excellent.

  • How to set a custom font for a spinner?

    - by AndrewC
    Is there anyway to set a custom font or color for the selected item in a Spinner? For example, I open the spinner and click a priority of "High". I'm my layout containing the spinner, I would like to see the word "High" in red or a custom font. I can't seem to obtain the textview to make the necessary change. I always obtain a NullPointerException if I typecast the spinner.getSelectedView() to textview and attempt to set the color. any ideas? thanks in advance!

  • Most efficient way to maintain a 'set' in SQL Server?

    - by SEVEN YEAR LIBERAL ARTS DEGREE
    I have ~2 million rows or so of data, each row with an artificial PK, and two Id fields (so: PK, ID1, ID2). I have a unique constraint (and index) on ID1+ID2. I get two sorts of updates, both with a distinct ID1 per update. 100-1000 rows of all-new data (ID1 is new) 100-1000 rows of largely, but not necessarily completely overlapping data (ID1 already exists, maybe new ID1+ID2 pairs) What's the most efficient way to maintain this 'set'? Here are the options as I see them: Delete all the rows with ID1, insert all the new rows (yikes) Query all the existing rows from the set of new data ID1+ID2, only insert the new rows Insert all the new rows, ignore inserts that trigger unique constraint violations Any thoughts?

  • how do you set a property of a control to an address of a function in xaml?

    - by ambog36
    Hi, I have a control that has a "Filter" property that expects a function that defines how the contents of the control should be filtered. so far i am setting the filter in code behind as such: MyControl.Filter = AddressOf Filters.MyFilter In this example MyFilter is a shared function in the Filters class with the following signature: Public Shared Function MyFilter(ByVal obj As Object, ByVal text As String) As Boolean I would like to set this in xaml. I was thinking of setting the Filters.MyFilter as a static resource and setting it that way: ...Filter="{StaticResource myFilter}"/ but i cant set Filters.MyFilter as a static resource. Any ideas on how to achieve this? Thanks,

  • Is there any way to generate a set of JWebUnit tests from an apache rewrite config?

    - by robbbbbb
    Seems unlikely, but is there any way to generate a set of unit tests for the following rewrite rule: RewriteRule ^/(user|group|country)/([a-z]+)/(photos|videos)$ http:/whatever?type=$1&entity=$2&resource=$3 From this I'd like to generate a set of urls of the form: /user/foo/photos /user/bar/photos /group/baz/videos /country/bar/photos etc... The reason I don't want to just do this once by hand is that I'd like the bounded alternation groups (e.g. (user|group|country)) to be able to grow and maintain coverage without having the update the tests by hand. Is there a rewrite rule or regex parser that might be able to do this, or am I doing it by hand?

  • How to map a set of text as a whole to a node?

    - by JIpeng Tan
    Suppose I have a plain text file with the following data: DataSetOne <br /> content <br /> content <br /> content <br /> DataSetTwo <br /> content <br /> content <br /> content <br /> content <br /> ...and so on... What I want to to is: count how many contents in each data set. For example the result should be <DataSetOne, 3>, <DataSetTwo, 4> I am a beginer to hadoop, I wonder if there is a way to map a chunk of data as a whole to a node. for example, set all DataSetOne to node 1 and all DataSetTwo to node 2. Does anyone can give me an idea how to archive this?

  • Find all possible partitions of n elements with k-sized subsets, where two elements share same set o

    - by ypnos
    I have n=32 elements that need to be partitioned into 8 sets, each set has to hold exactly k=4 elements. I need to find all possible partitions with the constraint that each pair of elements only shares the same set once. So if I start with [1 2 3 4] [5 6 7 8] [...], all consecutive partitions cannot hold e.g. [1 2 X X] or [X X 1 3]. sets are unordered. Close to this problem are the stirling numbers of the second kind. However, they only solve the problem for arbitrarily sized sets.

  • How to use PHP Time function to set a time variable of '09:30', add a specific amount of seconds and

    - by Henry
    Hi guys, hopefully you can help me here. I have some code (please see below) which takes the current time, then adds specific seconds to the time and re-displays the time 1 minute in the future. Instead of the time being the current time, I want it to be a time which I set - say 9:30. Then I want to be able to add, for example 65 seconds and it shows me 9:31. Please can you show me how to change it from current time, to a specific time I can set myself. Thank you. <?php $my_time = date('h:i:s',time()); $seconds2add = 65; $new_time= strtotime($my_time); $new_time+=$seconds2add; echo date('h:i:s',$new_time); ?>

  • C++ How do you set an array of pointers to null in an initialiser list like way?

    - by boredjoe
    I am aware you cannot use an initialiser list for an array. However I have heard of ways that you can set an array of pointers to NULL in a way that is similar to an initialiser list. I am not certain how this is done. I have heard that a pointer is set to NULL by default, though I do not know if this is guaranteed/ in the C++ standard. I am also not sure if initialising through the new operator compared to normal allocation can make a difference too.

  • How to set baud rate to 307200 on Linux?

    - by cairol
    Basically I'm using the following code to set the baud rate of a serial port: struct termios options; tcgetattr(fd, &options); cfsetispeed(&options, B115200); cfsetospeed(&options, B115200); tcsetattr(fd, TCSANOW, &options); This works very well. But know I have to communicate with a device that uses a baud rate of 307200. How can I set that? cfsetispeed(&options, B307200); doesn't work, there is no B307200 defined.

  • I set a global bug catcher in my application for unhandled exceptions and it is picking up all exceptions

    - by user1632018
    I am trying to figure out why this is happing. In my vb.net application I set a global handler in the ApplicationEvents.vb which I thought would only pick up any unhandled exceptions, although it is picking up every exception that happens in my application whether or not they are handled with try catch blocks. Here is my code in applicationevents Private Sub MyApplication_UnhandledException(ByVal _ sender As Object, ByVal e As _ Microsoft.VisualBasic.ApplicationServices.UnhandledExceptionEventArgs) _ Handles Me.UnhandledException e.ExitApplication = _ MessageBox.Show(e.Exception.Message & _ vbCrLf & "The application has encountered a bug, would you like to Continue?", "An Error has occured.", _ MessageBoxButtons.YesNo, _ MessageBoxIcon.Question) _ = DialogResult.No End Sub In the rest of my application I set normal try catch blocks like this: Try Catch ex as exception End Try Can anyone tell me why this is happening?

  • .Net Compact Framework - is there any way in the SerialPort class to set the RTS control to TOGGLE ?

    - by egapotz
    Hi, I found very annoying the fact that the SerialPort class in the .NET Framework doesn't allow to set the rts control to TOGGLE. There is a property called RTSEnable that lets me control directly the status of the RTS signal, but in a Compact Framework app there is not much precision to make it work well. Another solution can be to write a class that calls unmanaged APIs and set the rts control via the DCB structure, but I don't like it since I am using some external libraries that need to reference to a SerialPort instance. Have you any other idea ? Thanks !
