  • Scaling up an image

    - by codefail
    How do I fulfill the condition "returns the entire scaled up image" If I am coding this correctly, scaleColor handles individual colors, getRed handles the red, etc. I am multiplying this by the input, numTimes, which will create a new image that is scaled up it. This scaled up (increase size) is to be returned. This is what I have. Image Image::scaleUp(int numTimes) const { for (int x = 0; x < width; x++) { for (int y = 0; y < height; y++) { pixelData[x][y].scaleColor(pixelData[x][y].scaleRed(pixelData[x][y].getRed()*numTimes)); pixelData[x][y].scaleColor(pixelData[x][y].scaleGreen(pixelData[x][y].getGreen()*numTimes)); pixelData[x][y].scaleColor(pixelData[x][y].scaleBlue(pixelData[x][y].getBlue()*numTimes)); } } //return Image(); }

  • PHP upload file using PUT instead of POST

    - by Marco Demaio
    I read something about this on PHP docs, but it's not celar to me: Do the most widely used browsers (IE, FF, Chrome, Safari, Opera, ...) support this PUT method to uplaod files? What HTML should I write to make the browser call the server via PUT request. I mean do I need to write a FORM with an INPUT file field and just replace the attribute method="POST" with the method="PUT"? On the PHP docs (link above) they say a PUT request is much simplier than a POST request when uploading file, along with this advantage, what other advantages/disadvanatges do the PUT has comapred to teh POST? Thanks!

  • gethostbyname in C

    - by Matic
    I don't know how to write applications in C, but I need a tiny program that does: lh = gethostbyname("localhost"); output = lh->h_name; output variable is to be printed. The above code is used in PHP MongoDB database driver to get the hostname of the computer (hostname is part of an input to generate an unique ID). I'm skeptical that this will return the hostname, so I'd like some proof. Any code examples would be most helpful. Happy day, Matic

  • Any good GUI tool to easily create stored procs SQL server 2008 ?

    - by Munish Goyal
    The templates for stored-procs in SSMS do not auto-populate all input columns, again there is manual work involved. I am looking for something like right-click on table and say CREATE stored-proc, and then it allows to pick a template, based on which it can populate the parameters etc. and give check-box in GUI (like table designer, you can easily add/remove a column). Some support for change management with table undergoing alter or otherwise would also be helpful. Currently we manually write all stored-procs, which i think we should be able to save time and labor with automation. Any suggestion on other free 3rd party tools ?

  • How often to run getWritableDatabase() and getReadableDatabase()?

    - by jawonlee
    I'm writing a Service, a Content Provider, and one or more apps. The Service writes new data to the Content Provider's SQLite database every 5 minutes or so plus at user input, and is intended to run pretty much forever in the background. The app, when running, will display data pulled from the Content Provider, and will be refreshed whenever the Service puts more data into the Content Provider's database. Given that the Service only inserts into the database once every five minutes, when is the right time to call SQLiteOpenHelper's getWritableDatabase() / getReadableDatabase()? Is it on the onCreate() of the Content Provider, or should I run it every time there is an insert() and close it at the end of insert()? The data being inserted every 5 minutes will contain multiple inserts.

  • How do I get callgrind to dump source line information?

    - by Jeremybub
    I'm trying to profile a shared library on GNU/Linux which does real-time audio processing, so performance is important. I run another program which hooks it up to the audio input and output of my system, and profile that with callgrind. Looking at the results in KCacheGrind, I get great information about what functions are taking up most of my time. However, it won't let me look at the line by line information, and instead says I need to compile it with debugging symbols and run the profiling again. The program which I am profiling is not compiled with debug symbols, but the library is. And I know this, because interestingly, source code annotations for cachegrind work fine. When I run callgrind, it says the default is to dump source line information, but it just isn't doing that. Is there some way I could force it to, or figure out what's stopping it?

  • VB.NET - using textfile as source for menus and textboxes

    - by Kenny Bones
    Hi, this is probably a bit tense and I'm not sure if this is possible at all. But basically, I'm trying to create a small application which contains alot of PowerShell-code which I want to run in an easy matter. I've managed to create everything myself and it does work. But all of the PowerShell code is manually hardcoded and this gives me a huge disadvantage. What I was thinking was creating some sort of dynamic structure where I can read a couple of text files (possible a numerous amount of text files) and use these as the source for both the comboboxes and the richtextbox which provovides as the string used to run in PowerShell. I was thinking something like this: Combobox - "Choose cmdlet" - Use "menucode.txt" as source Richtextbox - Use "code.txt" as source But, the thing is, Powershell snippets need a few arguments in order for them to work. So I've got a couple of comboboxes and a few textboxes which provides as input for these arguments. And this is done manually as it is right now. So rewriting this small application should also search the textfile for some keywords and have the comboboxes and textboxes to replace those keywords. And I'm not sure how to do this. So, would this requre a whole lot of textfiles? Or could I use one textfile and separate each PowerShell cmdlet snippets with something? Like some sort of a header? Right now, I've got this code at the eventhandler (ComboBox_SelectedIndexChanged) If ComboBoxFunksjon.Text = "Set attribute" Then TxtBoxUsername.Visible = True End If If chkBoxTextfile.Checked = True Then If txtboxBrowse.Text = "" Then MsgBox("You haven't choses a textfile as input for usernames") End If LabelAttribute.Visible = True LabelUsername.Visible = False ComboBoxAttribute.Visible = True TxtBoxUsername.Visible = False txtBoxCode.Text = "$users = Get-Content " & txtboxBrowse.Text & vbCrLf & "foreach ($a in $users)" & vbCrLf & "{" & vbCrLf & "Set-QADUser -Identity $a -ObjectAttributes @{" & ComboBoxAttribute.SelectedItem & "='" & TxtBoxValue.Text & "'}" & vbCrLf & "}" If ComboBoxAttribute.SelectedItem = "Outlook WebAccess" Then TxtBoxValue.Visible = False CheckBoxValue.Visible = True CheckBoxValue.Text = "OWA Enabled?" txtBoxCode.Text = "$users = Get-Content " & txtboxBrowse.Text & vbCrLf & "foreach ($a in $users)" & vbCrLf & "{" & vbCrLf & "Set-CASMailbox -Identity $a -OWAEnabled" & " " & "$" & CheckBoxValue.Checked & " '}" & vbCrLf & "}" End If If ComboBoxAttribute.SelectedItem = "MobileSync" Then TxtBoxValue.Visible = False CheckBoxValue.Visible = True CheckBoxValue.Text = "MobileSync Enabled?" Dim value If CheckBoxValue.Checked = True Then value = "0" Else value = "7" End If txtBoxCode.Text = "$users = Get-Content " & txtboxBrowse.Text & vbCrLf & "foreach ($a in $users)" & vbCrLf & "{" & vbCrLf & "Set-QADUser -Identity $a -ObjectAttributes @{msExchOmaAdminWirelessEnable='" & value & " '}" & vbCrLf & "}" End If Else LabelAttribute.Visible = True LabelUsername.Visible = True ComboBoxAttribute.Visible = True txtBoxCode.Text = "Set-QADUser -Identity " & TxtBoxUsername.Text & " -ObjectAttributes @{" & ComboBoxAttribute.SelectedItem & "='" & TxtBoxValue.Text & " '}" If ComboBoxAttribute.SelectedItem = "Outlook WebAccess" Then TxtBoxValue.Visible = False CheckBoxValue.Visible = True CheckBoxValue.Text = "OWA Enabled?" txtBoxCode.Text = "Set-CASMailbox " & TxtBoxUsername.Text & " -OWAEnabled " & "$" & CheckBoxValue.Checked End If If ComboBoxAttribute.SelectedItem = "MobileSync" Then TxtBoxValue.Visible = False CheckBoxValue.Visible = True CheckBoxValue.Text = "MobileSync Enabled?" Dim value If CheckBoxValue.Checked = True Then value = "0" Else value = "7" End If txtBoxCode.Text = "Set-QADUser " & TxtBoxUsername.Text & " -ObjectAttributes @{msExchOmaAdminWirelessEnable='" & value & "'}" End If End If Now, this snippet above lets me either use a text file as a source for each username used in the powershell snippet. Just so you know :) And I know, this is probably coded as stupidly as it gets. But it does work! :)

  • Django: Geocoding an address on form submission?

    - by User
    Trying to wrap my head around django forms and the django way of doing things. I want to create a basic web form that allows a user to input an address and have that address geocoded and saved to a database. I created a Location model: class Location(models.Model): address = models.CharField(max_length=200) city = models.CharField(max_length=100) state = models.CharField(max_length=100, null=True) postal_code = models.CharField(max_length=100, null=True) country = models.CharField(max_length=100) latitude = models.DecimalField(max_digits=18, decimal_places=10, null=True) longitude = models.DecimalField(max_digits=18, decimal_places=10, null=True) And defined a form: class LocationForm(forms.ModelForm): class Meta: model = models.Location exclude = ('latitude','longitude') In my view I'm using form.save() to save the form. This works and saves an address to the database. I created a module to geocode an address. I'm not sure what the django way of doing things is, but I guess in my view, before I save the form, I need to geocode the address and set the lat and long. How do I set the latitude and longitude before saving?

  • Given two lines on a plane, how to find integer points closest to their intersection?

    - by Lukasz Lew
    I can't solve it: You are given 8 integers: A, B, C representing a line on a plane with equation A*x + B*y = C a, b, c representing another line x, y representing a point on a plane The two lines are not parallel therefore divide plane into 4 pieces. Point (x, y) lies inside of one these pieces. Problem: Write a fast algorithm that will find a point with integer coordinates in the same piece as (x,y) that is closest to the cross point of the two given lines. Note: This is not a homework, this is old Euler-type task that I have absolutely no idea how to approach. Update: You can assume that the 8 numbers on input are 32-bit signed integers. But you cannot assume that the solution will be 32 bit.

  • Force CL-Lex to read whole word

    - by Flávio Cruz
    I'm using CL-Lex to implement a lexer (as input for CL-YACC) and my language has several keywords such as "let" and "in". However, while the lexer recognizes such keywords, it does too much. When it finds words such as "init", it returns the first token as IN, while it should return a "CONST" token for the "init" word. This is a simple version of the lexer: (define-string-lexer lexer (...) ("in" (return (values :in $@))) ("[a-z]([a-z]|[A-Z]|\_)" (return (values :const $@)))) How do I force the lexer to fully read the whole word until some whitespace appears?

  • Trying to get Package Version Information to display in an "About" message.

    - by user313135
    Hello, I have been struggling with getting the versionName for a running application from the PackageInfo Object type. I have constructed a Parcelable Interface with all of the fields associated with the PackageInfo Object type. The primary input for that interface method is a Parcel object. I cannot seem to figure out how to correctly associate these Parcelable, Parcel, and PackageInfo objects. Is there any sample code out there that I can look at? Doesn't seem like it should be that difficult but it seems to be stumping me. Thanks Jazz

  • Optimize C# Code Fragment

    - by Eric J.
    I'm profiling some C# code. The method below is one of the most expensive ones. For the purpose of this question, assume that micro-optimization is the right thing to do. Is there an approach to improve performance of this method? Changing the input parameter to p to ulong[] would create a macro inefficiency. static ulong Fetch64(byte[] p, int ofs = 0) { unchecked { ulong result = p[0 + ofs] + ((ulong)p[1 + ofs] << 8) + ((ulong)p[2 + ofs] << 16) + ((ulong)p[3 + ofs] << 24) + ((ulong)p[4 + ofs] << 32) + ((ulong)p[5 + ofs] << 40) + ((ulong)p[6 + ofs] << 48) + ((ulong)p[7 + ofs] << 56); return result; } }

  • php replace regular expression

    - by Enkay
    I need to use php to add a space between a period and the next word/letter when there's none. For example, "This is a sentence.This is the next one." needs to become "This is a sentence. This is the next one." Notice the added space after the first period. My problem is that even if I'm able to make a regular expression that finds every dot followed by a letter, how do I then replace that dot with a "dot + space" and keep the letter? Also it needs to keep the case of the letter, lower or upper. Thanks for your input.

  • HTML element to use as a Javascript message display

    - by javanix
    I have a message display field on my website that I'd like to change the value of via JS. I've been using just a textfield, disabling it, and modifying the value via a JS function (after using a little CSS to make it not look like a text field): <input type="text" id="message" style="background: white; color: black" size="50" disabled> There has to be a better way (for instance, formatting is tricky whenever the message runs over the specified size), but I can't think of it off the top of my head. Can anyone point me in a better direction? Thanks! FYI: I am doing a timer function which I'd like to look something like "HH:MM:SS | 'my message here'"

  • Question regarding checking the state of a checkbox class

    - by Joseph
    I'll try and make this question simple. Can I assign a class to a series of different checkboxes, and use Jquery to do something when any one of those checkboxes is checked? Searching around on the internet I have found documentation on grabbing the name: $('input[name=foo]').is(':checked') but when I swap out the name attribute for the class attr, it won't work! How can I set an event to occur if any of the checkboxes with this certain class is checked? Please help me out! Thanks

  • Convert matched string of UTF-8 values to UTF-8 characters in Ruby

    - by user1475154
    Trying to convert output from a rest_client GET to the characters that are represented with escape sequences. Input: ..."sub_id":"\u0d9c\u8138\u8134\u3f30\u8139\u2b71"... (which I put in 'all_subs') Match: m = /sub_id\"\:\"([^\"]+)\"/.match(all_subs.to_str) [1] Print: puts m.force_encoding("UTF-8").unpack('U*').pack('U*') But it just comes out the same way I put it in. ie, "\u0d9c\u8138\u8134\u3f30\u8139\u2b71" However, if I convert a raw string of it: puts "\u0d9c\u8138\u8134\u3f30\u8139\u2b71".unpack('U*').pack('U*') The output is perfect as "??????"

  • Access ASP.NET control using javascript

    - by user3036965
    I have a basic javascript function like this which works as I am able to dynamically change the textbox in a javascript method at runtime. function MyTst(pVal2) { var x = document.getElementById('<%=myImage.ClientID%>'); x.src = "/images/write.gif"; } In the above code I need to be generic. So replace '<%=myImage.ClientID%' with the input param to my method which in this instance is called pVal2 and contains the asp.net server control image id. Can anyone advise on an approach to do this. I've tried lots of things and just cant seem to get it working. Thanks for any advice.

  • How should I build a privacy drop-down (select) menu?

    - by animuson
    I'm trying to build something similar to Facebook's privacy selection menu, except without the 'custom' option. It will only list a few options such as 'show to all', 'show to friends only', or 'completely hidden'. Right now I'm thinking of using simple JavaScript to change a hidden input field to the new value they click on, so if they clicked on the division for 'show to friends only' it would change the corresponding field, say 'email_privacy', to 1. Is there a better way to do this or am I pretty much on track? P.S. I am not planning on using a select element, I was planning on building a custom drop-down menu using CSS since select elements are so highly non-customizable. I'm doing it this way to save space, rather than having this massive selection menu at the right which takes up a bunch of space. Note: I'm not really interested in using jQuery, that's just extra libraries and crap that I don't want to load. I can do it in JavaScript just as easily so I might as well use that.

  • How to programmatically set a data cell of database in VB.Net?

    - by manuel
    I have a Microsoft Access database file connected to VB.NET. In the database table, I have a 'No.' and a 'Status' column. Then I have a textbox where I can input an integer. I also have a button, which will change the data cell in 'Status' where 'No.' = textbox.Text(), when I click it. Let's say I want the 'Status' cell to be changed to "Low". What codes should I put in the button_Click event handler? Here is the codes I used to retrieve and display the database table. Public Class theForm Dim con As New OleDb.OleDbConnection Dim ds As New DataSet Dim daTitles As OleDb.OleDbDataAdapter Private Sub theForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load con.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=|DataDirectory|\db1.mdb" con.Open() daTitles = New OleDb.OleDbDataAdapter("SELECT * FROM Titles", con) daTitles.Fill(ds, "Titles") DataGridView1.DataSource = ds.Tables("Titles") DataGridView1.AutoResizeColumns() End Sub

  • AJAX call + JQuery Dialog Title changing dynamically

    - by Panther24
    I have an AJAX call which loads an Dialog page, now depending upon the content of the data returned on the AJAX call, I want to change the title of the Window, how do I do that. Here is the snippet of code: var divid = "brHistoryForm"; var url = "getRestoreFiles.action?profileName="+profileName; // Create xmlHttp var xmlHttp = AJAX(); // The code... xmlHttp.onreadystatechange=function(){ if(xmlHttp.readyState==4){ document.getElementById(divid).innerHTML=xmlHttp.responseText; } } xmlHttp.open("GET",url,true); xmlHttp.send(null); $('#brHistoryForm').dialog('open'); jQuery('#brHistoryForm').focus(); document.getElementById('pageTitle').innerHTML = "<h2>"+profileName+" - B&R History</h2>" Here 'pageTitle' is a div. When I run the above piece of code, it opens a dialog window, the action is redirected to a jsp page which is loaded inside the div. It works fine, but the title does not get set :(. I've tried to do the setting of the title in the redirected jsp page, it doesn't work either. Here is the code of that JSP page: <%@page contentType="text/html" pageEncoding="UTF-8"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <%@ taglib prefix="s" uri="/struts-tags" %> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>B&R History</title> </head> <body> <table style="width: 100%"> <tr> <td style="width: 40%"> <div id="pageTitle"> <h2>B&R History</h2> </div> </td> </tr> </table> <table id="diskTable" cellpadding="0" cellspacing="0" border="1" class="display"> <thead> <tr> <th>Select</th><th>Operation</th> <th>Source</th><th>Destination</th> <th>Status</th><th>Start Time</th><th>End Time</th> </tr> </thead> <tfoot></tfoot> <tbody> <s:iterator value="restoreFileList"> <tr> <td> <s:if test="%{status.equals('Finished')}"> <input onClick="loadRestoreForm('<s:property value="name"/>', '<s:property value="to_path"/>', '<s:property value="status"/>')" type="radio" name='chk' id="chk" value="<s:property value='id'/>,<s:property value="status"/>" > </s:if> <s:else> <input type="radio" name='chk' id="chk" value="<s:property value='id'/>,<s:property value="status"/>" disabled> </s:else> </td> <td> <s:if test="%{br_type == 0}"> Backup </s:if> <s:else> Restore </s:else> </td> <td><s:property value="from_path"/></td> <td><s:property value="to_path"/></td> <td><s:property value="status"/></td> <td><s:property value="start_time"/></td> <td><s:property value="end_time"/></td> </tr> </s:iterator> </tbody> </table> </body> </html> Any help would be appreciated.

  • RedirectStandardInput crashes program

    - by Roman
    Hi, the following code is to open a console application (which uses pdcurses for output, nothing special): myProcess.StartInfo.FileName = "some.exe"; myProcess.StartInfo.UseShellExecute = false; myProcess.StartInfo.CreateNoWindow = false; myProcess.StartInfo.RedirectStandardInput = true; myProcess.Start(); The Problem is that it opens the designated window but directly closes it (it's barely visible). Starting the program without RedirectStandardInput works. The problem is that it does not throw an exception nor any error-message. What is wrong with my code? How can I write input to the program? Thanks.
