  • How do You Center a TextView in Layout?

    - by Ken
    I have a complex layout, part of which features a value centered over a label, with + and - buttons on either side of the value. I want the value to center between the buttons, whether it is "1" or "99". It looks fine when it's a 2-digit number like "99", but when it's a single digit the number is left-justified. How do I properly center that value? Here's the portion of my layout that does this: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_above="@id/runway_label" android:layout_centerHorizontal="true" android:orientation="horizontal"> <ImageView android:id="@+id/dec_runway_button" android:src="@drawable/minus_button" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_vertical"/> <TextView android:id="@+id/runway_value" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textColor="#FFFFFF" android:textStyle="bold" android:textSize="40.0sp" android:minWidth="50sp" android:layout_centerInParent="true" android:layout_gravity="center" android:shadowColor="#333333" android:shadowDx="2.0" android:shadowDy="2.0" android:shadowRadius="3.0" /> <ImageView android:id="@+id/inc_runway_button" android:src="@drawable/plus_button" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_vertical"/> </LinearLayout>

  • ORA-01019 error only as an administrator

    - by Mike
    I'm having a strange problem. I've installed the Oracle 10g client on a terminal server running Windows Server 2008R2. When I try to connect to Oracle, using, say, Toad, I receive the error "ORA-01019 unable to allocate memory in the user side". But this only happens if I'm logged in as an administrator. If I connect as a normal user, I can connect without issue. Also -- if a normal user is connected, I can then connect without a problem as an administrator. Any thoughts?

  • Intel Assembly Programming

    - by Kay
    class MyString{ char buf[100]; int len; boolean append(MyString str){ int k; if(this.len + str.len>100){ for(k=0; k<str.len; k++){ this.buf[this.len] = str.buf[k]; this.len ++; } return false; } return true; } } Does the above translate to: start: push ebp ; save calling ebp mov ebp, esp ; setup new ebp push esi ; push ebx ; mov esi, [ebp + 8] ; esi = 'this' mov ebx, [ebp + 14] ; ebx = str mov ecx, 0 ; k=0 mov edx, [esi + 200] ; edx = this.len append: cmp edx + [ebx + 200], 100 jle ret_true ; if (this.len + str.len)<= 100 then ret_true cmp ecx, edx jge ret_false ; if k >= str.len then ret_false mov [esi + edx], [ebx + 2*ecx] ; this.buf[this.len] = str.buf[k] inc edx ; this.len++ aux: inc ecx ; k++ jmp append ret_true: pop ebx ; restore ebx pop esi ; restore esi pop ebp ; restore ebp ret true ret_false: pop ebx ; restore ebx pop esi ; restore esi pop ebp ; restore ebp ret false My greatest difficulty here is figuring out what to push onto the stack and the math for pointers. NOTE: I'm not allowed to use global variables and i must assume 32-bit ints, 16-bit chars and 8-bit booleans.

  • tree view; show lines property is not working properly

    - by Jibu P C
    Hii, I am a bigginer in using tree view control. I am using tree view control to make a simple tree like structure. But when i use show lines property it is not connecting to the root node. The code which i have written is as follows. <asp:TreeView ID="treeSettings" runat="server" ImageSet="Simple2" NodeIndent="15" ShowLines="True"> <ParentNodeStyle Font-Bold="False" /> <HoverNodeStyle BackColor="#CCCCCC" BorderColor="#888888" BorderStyle="None" Font-Underline="True" /> <SelectedNodeStyle BackColor="#FFCCCC" Font-Underline="False" HorizontalPadding="0px" VerticalPadding="1px" Height="0px" /> <Nodes> <asp:TreeNode Text="Settings" Value="Settings"> <asp:TreeNode Text="Edit Task" Value="Edit Task"></asp:TreeNode> <asp:TreeNode Text="Assign" Value="Assign a Resource"></asp:TreeNode> <asp:TreeNode Text="Task Status" Value="Task Status"></asp:TreeNode> </asp:TreeNode> </Nodes> <NodeStyle Font-Names="Verdana" Font-Size="8pt" ForeColor="Black" HorizontalPadding="0px" NodeSpacing="1px" VerticalPadding="0px" Width="100px" ChildNodesPadding="0px" /> <LeafNodeStyle NodeSpacing="0px" /> </asp:TreeView>enter code here`

  • Spring - Transaction Readonly

    - by AAK
    Hello Gurus! Just wanted your expert opinions on declarative transaction management for Spring. Here is my setup - A. DAO Layer is Plain old JDBC using jdbcTemplete (No hibernate etc) B. Service Layer is POJO with declarative trasnactions as follows - save*, readonly=false, rollback for Throwable Things work fine with above setup. However when I say get*, readonly=true I see errors in my log file saying - Database connection cannot be marked as readonly. This happens for all get* methods in Service Layer. Now my questions - A. Do I have to say get* as readonly? All my get* methods are pure read DB operations. I do not wish to run them in any transaction context. How serious is the above error? B. When I remove the get* confiiguration, I do not see the errors, morever all my simple get* operations are performed without transactions. Is this the way to go? C. Why would anyone want to have transactional methods where readonly = true? Is there any practical significance of this configuration? Thank you! As always your resposes are much appreciated!

    Hi Everyone, Im working in a game and when the player finished the level , Im asking the Player to enter his name on EditText in Alert Dialog : AlertDialog.Builder builder = new Builder(this); LayoutInflater inflater = getLayoutInflater(); // Inflate and set the layout for the dialog // Pass null as the parent view because its going in the dialog layout builder.setView(inflater.inflate(R.layout.dialog_name, null)) // Add action buttons .setPositiveButton(R.string.alertName, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int id) { playerText = (EditText) ((AlertDialog)dialog).findViewById(R.id.username); if(playerText.getText() != null && playerText.getText().length() != 0) Helper.currentPlayer.setName(playerText.getText().toString()); //calculate the score // save in data base PlayerDataSource playerDS = new PlayerDataSource(getApplicationContext()); playerDS.open(); Helper.currentPlayer = playerDS.createPlayer(Helper.currentPlayer.getName(), Helper.currentPlayer.getScore(), Helper.currentPlayer.levels, Helper.currentPlayer.times, LanguageHelper.div); playerDS.close(); saveStmc(); mainScene.setChildScene(choicesMenu, false, true, true); } }) .setTitle("Please Enter Your name") .setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { } }); alert = builder.create(); When the Player enters his name and press OK (Positive button) I will check in database if the name exists or not, if the name is exist : show Toast and not dismiss the alert to write another name. How to do that?

  • Better performance with memcached cluster or local memcaches?

    - by Nicholas Tolley Cottrell
    I have a small cluster of servers balancing a Java web app. Currently I have 3 memcached servers caching data and all web apps shares all 3 memcached instances. I often get strange slowdowns and timeouts to some of the memcacheds and I wondering if there is a good way of analyzing the performance. I am wondering whether my iptables rules (or some other system limitation) are blocking/slowing connections. I am considering reconfiguring the web apps so that they only query the memcached process on their own localhost.

  • How to store a public key in a machine-level RSA key container

    - by Andrew Kimball
    I'm having a problem using a machine level RSA key container when storing only the public key of a public/private key pair. The following code creates a public/private pair and extracts the public key from that pair. The pair and the public key are stored in separate key containers. The keys are then obtained from those key containers at which point they should be the same as the keys going into the containers. The code works when CspProviderFlags.UseDefaultKeyContainer is specified for CspParameters.Flags (i.e. the key read back out from the PublicKey container is the same), but when CspProviderFlags.UseMachineKeyStore is specified for CspParameters.Flags the key read back from PublicKey is different. Why is the behaviour different, and what do I need to do differently to retrieve the public key from a machine-level RSA key container? var publicPrivateRsa = new RSACryptoServiceProvider(new CspParameters() { KeyContainerName = "PublicPrivateKey", Flags = CspProviderFlags.UseMachineKeyStore //Flags = CspProviderFlags.UseDefaultKeyContainer } ) { PersistKeyInCsp = true, }; var publicRsa = new RSACryptoServiceProvider(new CspParameters() { KeyContainerName = "PublicKey", Flags = CspProviderFlags.UseMachineKeyStore //Flags = CspProviderFlags.UseDefaultKeyContainer } ) { PersistKeyInCsp = true }; //Export the key. publicRsa.ImportParameters(publicPrivateRsa.ExportParameters(false)); Console.WriteLine(publicRsa.ToXmlString(false)); Console.WriteLine(publicPrivateRsa.ToXmlString(false)); //Dispose those two CSPs. using (publicRsa) { publicRsa.Clear(); } using (publicPrivateRsa) { publicRsa.Clear(); } publicPrivateRsa = new RSACryptoServiceProvider(new CspParameters() { KeyContainerName = "PublicPrivateKey", Flags = CspProviderFlags.UseMachineKeyStore //Flags = CspProviderFlags.UseDefaultKeyContainer } ); publicRsa = new RSACryptoServiceProvider(new CspParameters() { KeyContainerName = "PublicKey", Flags = CspProviderFlags.UseMachineKeyStore //Flags = CspProviderFlags.UseDefaultKeyContainer } ); Console.WriteLine(publicRsa.ToXmlString(false)); Console.WriteLine(publicPrivateRsa.ToXmlString(false)); using (publicRsa) { publicRsa.Clear(); } using (publicPrivateRsa) { publicRsa.Clear(); }

  • Gmail firing background tasks in Chrome and Firefox

    - by Keith Bloom
    I am experiencing a strange problem with Gmail running on Vista and it started when WindowsUpdate last patched my computer. Since then when Gmail is open in either Chrome or Safari the pointer changes to the Working in Background state every couple of seconds. You can imagine how distracting this is. I have never used Gmail in IE before so I loaded it up, Gmail wanted to load the GoogleTalk ActiveX control which I declined. Now Gmail in IE, I'm using version 8, didn't fire these background processes so I'm thinking it has something to do with GoogleTalk. Has anyone experienced this problem? Also does anyone know how to disable GoogleTalk in FireFox of Chrome.

  • pagination in jsf

    - by gurupriyan.e
    I would like your comments and suggestion on this. I am doing the pagination for a page in jsf. The datatable is bound to a Backing Bean property through the "binding" attribute. I have 2 boolean variables to determine whether to render 'Prev' and 'Next' Button - which is displayed below the datatable. When either the 'Prev' or 'Next' button is clicked, In the backing bean I get the bound dataTable property and through which i get the "first" and "rows" attribute of the datatable and change accordingly. I display 5 rows in the page. Please comment and suggest if there any better ways. btw, I am not interested in any JSF Component libraries but stick to only core html render kit. public String goNext() { UIData htdbl = getBrowseResultsHTMLDataTable1(); setShowPrev(true); //set Rows "0" or "5" if(getDisplayResults().size() - (htdbl.getFirst() +5)>5 ) { htdbl.setRows(5);//display 5 rows }else if (getDisplayResults().size() - (htdbl.getFirst() +5)<=5) { htdbl.setRows(0);//display all rows (which are less than 5) setShowNext(false); } //set First htdbl.setFirst(htdbl.getFirst()+5); return "success"; } public String goPrev() { setShowNext(true); UIData htdbl = getBrowseResultsHTMLDataTable1(); //set First htdbl.setFirst(htdbl.getFirst()-5); if(htdbl.getFirst()==0) { setShowPrev(false); } //set Rows - always display 5 htdbl.setRows(5);//display 5 rows return "success"; }

  • How to hide some nodes in Richfaces Tree (do not render nodes by condition)?

    - by VestniK
    I have a tree of categories and courses in my SEAM application. Courses may be active and inactive. I want to be able to show only active or all courses in my tree. I've decided to always build complete tree in my PAGE scope component since building this tree is quite expensive operation. I have boolean flag courseActive in the data wrapped by TreeNode<T>. Now I can't find the way to show courses node only if this flag is true. The best result I've achieved with the following code: <h:outputLabel for="showInactiveCheckbox" value="show all courses: "/> <h:selectBooleanCheckbox id="showInactiveCheckbox" value="#{categoryTreeEditorModel.showAllCoursesInTree}"> <a4j:support event="onchange" reRender="categoryTree"/> </h:selectBooleanCheckbox> <rich:tree id="categoryTree" value="#{categoryTree}" var="item" switchType="ajax" ajaxSubmitSelection="true" reRender="categoryTree,controls" adviseNodeOpened="#{categoryTreeActions.adviseRootOpened}" nodeSelectListener="#{categoryTreeActions.processSelection}" nodeFace="#{item.typeName}"> <rich:treeNode type="Category" icon="..." iconLeaf="..."> <h:outputText value="#{item.title}"/> </rich:treeNode> <rich:treeNode type="Course" icon="..." iconLeaf="..." rendered="#{item.courseActive or categoryTreeEditorModel.showAllCoursesInTree}"> <h:outputText rendered="#{item.courseActive}" value="#{item.title}"/> <h:outputText rendered="#{not item.courseActive}" value="#{item.title}" style="color:#{a4jSkin.inactiveTextColor}"/> </rich:treeNode> </rich:tree> the only problem is if some node is not listed in any rich:treeNode it just still shown with title obtained by Object.toString() method insted of being hidden. Does anybody know how to not show some nodes in the Richfases tree according to some condition?

  • embedded SWF isn't shown (SWFLoader)

    - by Trantec
    I embed a swf as ByteArray and load it at runtime with the SWFLoader. Here is the internal swf that I want to load: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Label id="rLabel" text="From InternalSWF"/> </mx:Application> The embeding swf loads it with the following code: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" applicationComplete="main();"> <mx:Script> <![CDATA[ import mx.managers.SystemManager; import mx.events.FlexEvent; [Embed(source="../../InternalSWF/bin-release/InternalSWF.swf", mimeType="application/octet-stream")] mimeType="application/octet-stream")] private const internalSWF:Class; public function main(): void { var binary:ByteArray = new internalSWF() as ByteArray; // setup swfloader rSwfLoader.trustContent = true; rSwfLoader.addEventListener( Event.COMPLETE, onSWFLoaded ); rSwfLoader.load(binary); } public function onSWFLoaded( event:Event ): void { } ]]> </mx:Script> <mx:Box> <mx:SWFLoader id="rSwfLoader" height="100%" width="100%" scaleContent="true"/> <mx:Text id="rText" text="from EmbedingSWF"/> </mx:Box> The label "from EmbedingSWF" is shown on both, local and on the webserver. But the label with "From InternalSWF" isn't shown on the webserver, just on the local machine. With some tests I found out that the internal swf is loaded correctly, because it's later added applicationComplete-Function is called. Is this a bug in Adobe-Flash-Player or am I missunderstanding something ? Update: Internet Explorer is fine. Firefox and Chrome not...

  • Hard link not works under MacOS in GUI mode

    - by AntonAL
    Hi, i faced a little strange behavior, while using hard links. From terminal, i create a text file 1.txt and a hard link "to this file" nano 1.txt mkdir dir ln 1.txt ./dir/ I check the resulting hard link and see that its contents are the same as of the original file. less ./dir/1.txt I change the initial file ... nano 1.txt ... and see, that changes was reflected in hard-link less ./dir/1.txt I change content of hard-link (more correct, of course - file, being referenced with hard-link) ... nano ./dir/1.txt ... and see, that changes are reflected in initial file less 1.txt Until now, all going well... Now, I close terminal and start playing with created files (1.txt and ./dir/1.txt) from Finder. When i change on this two files with TextEdit, changes are not reflected in another file. Just like the hard link was teared off... What is going on here ?

  • How is unautenticated site navigation handled in ASP.NET?

    - by Code Sherpa
    Hi. I am wondering how to do the following... I have a registration system. When the user successfully registers, he is then led down a series of data gathering pages (for his profile) and then, finally, ends on his profile's home page where he can start to use the site. All this happens without ever logging into the system so, he is unauthenticated and unconfirmed. My question is, how does this happen? How can I allow my user to be unauthenticated (and unconfirmed, but this I understand) and use all aspects of the Web site? The way I have things set up right now, my code should be doing this: case CreateProfileStatus.Success: //FormsAuthentication.SetAuthCookie(userName, false); Response.Redirect("NextPage.aspx", false); break; but, I am being redirected to the login page after registration which is not the result I want. This is what the relevant nodes in my web.config look like: <authentication mode="Forms"> <forms name=".AuthCookie" loginUrl="default.aspx" protection="All"/> </authentication> <authorization> <deny users="?"/> <allow roles="Administrators" /> </authorization> <anonymousIdentification enabled="true" cookieName=".ASPXANONYMOUS" cookieTimeout="100000" cookiePath="/" cookieRequireSSL="false" cookieSlidingExpiration="true" cookieProtection="Encryption" cookieless="UseCookies" domain="" /> When the user logs out after the registration and initial interaction with the site he will be required to log in upon return. At this point he must be authenticated but does not need to be confirmed for a period of time. Eventually, he will be reminded. So, how is this done? Thanks in advance.

  • jQuery Validation plugin results in empty AJAX POST

    - by user305412
    Hi, I have tried to solve this issue for at couple of days with no luck. I have a form, where I use the validation plugin, and when I try to submit it, it submits empty vars. Now, if I remove the validation, everything works fine. Here is my implementation: $(document).ready(function(){ $("#myForm").validate({ rules: { field1: { required: true, minlength: 5 }, field2: { required: true, minlength: 10 } }, messages: { field1: "this is required", field2: "this is required", }, errorLabelContainer: $("#validate_msg"), invalidHandler: function(e, validator) { var errors = validator.numberOfInvalids(); if (errors) { $("#validate_div").show(); } }, onkeyup: false, success: false, submitHandler: function(form) { doAjaxPost(form); } }); }); function doAjaxPost(form) { // do some stuff $(form).ajaxSubmit(); return false; } As I wrote this does not work when I have my validation, BUT if I remove that, and just add an onsubmit="doAjaxPost(this.form); return false"; to my HTML form, it works - any clue??? Now here is the funny thing, everything works as it should in Safari, but not in firefox 3.6.2 (Mac OS X)!

  • How would I structure the loop to go through inputs?

    - by dmanexe
    I am attempting to make a loop that will go through an array structured like this: $input[n][checked] $input[n][input] The 2nd input acts as a price multiplier, but doesn't have to exist (field can be blank). I don't think a foreach loop is right because I don't think it handles the inputs from the form in the correct dimensional array order to keep the information together. I have inputs on a form that look like this: <input type="checkbox" name="measure[<?php echo $item->id; ?>][checked]" value="<?php echo $item->id; ?>"> <input class="item_mult" type="text" name="measure[<?php echo $item->id; ?>][input]" /> I am attempting to make the loop go through and act as a multiplier on the input relative to its sibling field. (i.e. input[1][input] would be an integer that I want to retrieve later, grouped with input[1][checked]) <? $field = $this->input->post('measure',true); $totals = array(); foreach($field as $value): if ($value['input'] == TRUE) { $query = $this->db->get_where('items', array('id' => $value['input']))->row(); $totals[] = $query->price; ?> <p><?=$query->name?> - <?=money_format('%(#10n', $query->price)?></p> <?php } else { } endforeach; ?> And finally, the last code to array_sum and print the grand total: <? $grand_total = array_sum($totals); ?> <p><?=money_format('%(#10n', $grand_total)?></p> Eventually, I will need to store these records in a database, so I am sending complete item IDs through, etc.

  • What do I need to do to make sure my app launches as Admin?

    - by John Gietzen
    I'm writing an app that allows you to script the buttons from a wiimote into actions on your PC. It currently supports all of the features of the main remote control, except for the speaker. Now, I'm running in to trouble when I run it on Vista with UAC turned on. Any time a UAC'd window has focus, my app fails to move the mouse successfully. For instance, when an installer is run, I have to navigate it with the keyboard. Will running the app as administrator solve my problem? (At one point in time, I was able to successfully move the mouse over a UAC-password-entry box) How do I build a manifest that will tell windows to "run as administrator"? How do I embed this manifest into my app, if I'm strongly naming my assembly? How do I sign my application with an Authenticode cert? EDIT: Ok, so after some more extensive research, I have found: http://msdn.microsoft.com/en-us/library/bb756929.aspx <requestedExecutionLevel level="asInvoker|highestAvailable|requireAdministrator" uiAccess="true|false"/> However, the article says: Applications with the uiAccess flag set to true must be Authenticode signed to start properly. In addition, the application must reside in a protected location in the file system. \Program Files\ and \windows\system32\ are currently the two allowable protected locations. I have edited the question to reflect the new developments.

  • PHP text formating: Detectng several symbols in a row

    - by ilnur777
    I have a kind of strange thing that I really nead for my text formating. Don't ask me please why I did this strange thing! ;-) So, my PHP script replaces all line foldings "\n" with one of the speacial symbol like "|". When I insert text data to database, the PHP script replaces all line foldings with the symbol "|" and when the script reads text data from the database, it replaces all special symbols "|" with line folding "\n". I want to restrict text format in the way that it will cut line foldings if there are more than 2 line foldings used in each separating texts. Here is the example of the text I want the script to format: this is text... this is text... this is text...this is text...this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... I want to restict format like: this is text... this is text... this is text...this is text...this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... this is text... So, at the first example there is only one line folding between 2 texts and on the second example there are 3 line foldings between 2 texts. How it can be possible to replace more than 2 line foldings symbols "|" if they are detected on the text? This is a kind of example I want the script to do: $text = str_replace("|||", "||", $text); $text = str_replace("||||", "||", $text); $text = str_replace("|||||", "||", $text); $text = str_replace("||||||", "||", $text); $text = str_replace("|||||||", "||", $text); ... $text = str_replace("||||||||||", "||", $text); $text = str_replace("|", "<br>", $text);

  • How to use RelativeLayout to make a custom component on Android

    - by Styggentorsken
    I'm trying to make a custom component based on buttons without having to deal with all the layout myself. The problem is that i can't find a way to make use of RelativeLayout to draw the thing. This is my latest attempt. A bitmap is returned by layoutManager.getDrawingCache(), but it does not show any buttons. canvas.drawColor(...) however works. public class MyView extends View { Button myButton; RelativeLayout layoutManager; public MyView(Context context) { super(context); initMyView(); } public MyView(Context context, AttributeSet attrs) { super(context); initMyView(); // ... } public void initMyView() { layoutManager = new RelativeLayout(getContext()); } @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { setMeasuredDimension( MeasureSpec.getSize(measureSpec), MeasureSpec.getSize(measureSpec) ); } @Override protected void onDraw(Canvas canvas) { super.onDraw(canvas); myButton = new Button(layoutManager.getContext()); myButton.setVisibility(VISIBLE); myButton.setDrawingCacheEnabled(true); layoutManager.addView(myButton); layoutManager.setDrawingCacheEnabled(true); layoutManager.layout(0, 0, 150, 150); layoutManager.setVisibility(VISIBLE); layoutManager.buildDrawingCache(); layoutManager.draw(canvas); canvas.drawBitmap(layoutManager.getDrawingCache(), 0.0f, 0.0f, null); } }

  • Simple description of worker and I/O threads in .NET

    - by Konstantin
    It's very hard to find detailed but simple description of worker and I/O threads in .NET What's clear to me regarding this topic (but may not be technically precise): Worker threads are threads that should employ CPU for their work; I/O threads (also called "completion port threads") should employ device drivers for their work and essentially "do nothing", only monitor the completion of non-CPU operations. What is not clear: Although method ThreadPool.GetAvailableThreads returns number of available threads of both types, it seems there is no public API to schedule work for I/O thread. You can only manually create worker thread in .NET? It seems that single I/O thread can monitor multiple I/O operations. Is it true? If so, why ThreadPool has so many available I/O threads by default? In some texts I read that callback, triggered after I/O operation completion is performed by I/O thread. Is it true? Isn’t this a job for worker thread, considering that this callback is CPU operation? To be more specific – do ASP.NET asynchronous pages user I/O threads? What exactly is performance benefit in switching I/O work to separate thread instead of increasing maximum number of worker threads? Is it because single I/O thread does monitor multiple operations? Or Windows does more efficient context switching when using I/O threads?

  • Rails emails not sending in staging environment

    - by jrdioko
    In a Rails application I set up a new staging environment with the following parameters in its environments/ file: config.action_mailer.perform_deliveries = true config.action_mailer.raise_delivery_errors = true config.action_mailer.delivery_method = :smtp However, when the system generates an email, it gets printed to the staging.log file instead of being sent. My SMTP settings work fine in other environments. What configuration am I missing to get the emails to actually send? Edit: Yes, the staging box is set up with valid configuration for an SMTP server it has access to. It seems like the problem isn't with the SMTP settings (if it was, wouldn't I get errors in the logs?), but with the Rails configuration. The application is still redirecting emails to the log file (saying "Sent mail: ...") as opposed to actually going through SMTP. Edit #2: It looks like the emails actually have been sending correctly, they just happen to print to the log as well. I'm trying to use the sanitize_email gem to redirect the mail to another address, and that doesn't seem to be working, which is why I thought the emails weren't going out. So I think that solves my problem, although I'm still curious what in ActionMailer's settings controls whether emails are sent, logged to the log file, or both. Edit #3: The problem with sanitize_email boiled down to me needing to add the new staging environment to ActionMailer::Base.local_environments. I'll keep this question open to see if anyone can answer my last question (what determines whether ActionMailer's emails get sent out, logged to the log file, or both?)

This how the chart looks: Initialization This is how i initialize it: Dictionary<string, decimal> secondPersonsWithValues = HistoryModel.getSecondPersonWithValues(); decimal[] yValues = new decimal[secondPersonsWithValues.Values.Count]; //VALUES string[] xValues = new string[secondPersonsWithValues.Keys.Count]; //LABELS secondPersonsWithValues.Keys.CopyTo(xValues, 0); secondPersonsWithValues.Values.CopyTo(yValues, 0); incomeExpenseChart.Series["Default"].ChartType = System.Windows.Forms.DataVisualization.Charting.SeriesChartType.Pie; incomeExpenseChart.Series["Default"].Points.DataBindXY(xValues, yValues); incomeExpenseChart.ChartAreas["Default"].Area3DStyle.Enable3D = true; incomeExpenseChart.Series["Default"].CustomProperties = "PieLabelStyle=Outside"; incomeExpenseChart.Legends["Default"].Enabled = true; incomeExpenseChart.ChartAreas["Default"].Area3DStyle.LightStyle = System.Windows.Forms.DataVisualization.Charting.LightStyle.Realistic; incomeExpenseChart.Series["Default"]["PieDrawingStyle"] = "SoftEdge"; Basically i am querying data from database using the HistoryModel.getSecondPersonWithValues(); to get pairs as Dictionary<string, decimal> where key is the person and value is ammount. Problem #1 What i need is to be able to change the marked labels from person names to the ammounts or add another label of ammounts with the same colors (See Image). Problem #2 Another problem is that i need to change the view angle of 3D Pie chart. Maybe it's very simple and I just don't know the needed property or maybe i need to override some paint event. Either ways any kind of ways would be appriciated. Thanks in advance George.

  • Can't run telnet in console opened by Autohotkey

    - by Steve Crane
    I have enabled the telnet client on my Windows 7 64-bit machine and if I open the start menu and launch cmd from there I can run telnet. I normally use the keyboard shortcut Win-C, implemented by this AutoHotkey snippet to open a console. #c::Run, C:\WINDOWS\system32\cmd.exe For some strange reason when I try to run telnet in a console window opened this way I get Microsoft Windows [Version 6.1.7601] Copyright (c) 2009 Microsoft Corporation. All rights reserved. C:\Users\Steve\Documentstelnet 'telnet' is not recognized as an internal or external command, operable program or batch file. Running path in any console, regardless of how it was opened produces the same output. Can anyone shed any light on why telnet might run in one console but not the other?

  • Scope of This JavaScript Variable

    - by dkris
    I have a question and an issue wrt the code below: My question is what is the scope of the variable loaded here. The reason why i ask this is the onload="if(loaded==1)inittextarea() code is working fine on Firefox and not IE8. Why is this happening? Is there something specific i need to do here? Or is it not a valid practice? <html> <head> <title>Some Page</title> <link rel="stylesheet" href="../css/default.css" type="text/css"> <script type="text/javascript"> var loaded = 0; /*Point of interest*/ function jsLoaded() { loaded =1; } </script> <script type="text/javascript"> function inittextarea() { alert("test") tinyMCE.init({ elements : "content", theme : "advanced", readonly : true, mode : "exact", theme : "advanced", readonly : true, setup : function(ed) { ed.onInit.add(function() { tinyMCE.activeEditor.execCommand("mceToggleVisualAid"); }); } }); } </script> <script src="../js/tiny_mce/tiny_mce.js" onload="jsLoaded()" type="text/javascript"></script> </head> <body onload="if(loaded==1)inittextarea()"><!--Works on Firefox only--> *Usual stuff* </body></html> Any pointers please?

  • Java OutOfMemoryError message changes when trying to create Arrays of different sizes

    - by Gordon
    In the question by DKSRathore How to simulate the Out Of memory : Requested array size exceeds VM limit some odd behavior was noted when creating an arrays. When creating an array of size Integer.MAX_VALUE an exception with the error java.lang.OutOfMemoryError Requested array size exceeds VM limit was thrown. However when an array was created with a size less than the max but still above the virtual machine memory limit the error message read java.lang.OutOfMemoryError: Java heap space. Testing further I managed to narrow down where the error messages changes. long[] l = new long[2147483645]; exceptions message reads - Requested array size exceeds VM limit long[] l = new long[2147483644]; exceptions message reads - Java heap space errors I increased my virtual machine memory and still produced the same result. Has anyone any idea why this happens? Some extra info: Integer.MAX_VALUE = 2147483647. Edit: Here's the code I used to find the value, might be helpful. int max = Integer.MAX_VALUE; boolean done = false; while (!done) { try { max--; // Throws an error long[] l = new long[max]; // Exit if an error is no longer thrown done = true; } catch (OutOfMemoryError e) { if (!e.getMessage().contains("Requested array size exceeds VM limit")) { System.out.println("Message changes at " + max); done = true; } } }
