  • Vertical text in a Horizontal UIButton

    - by ArQangel
    I'm using a vertical UIButton in a portrait app (Just a normal button that is of width 60 and Height 160) I want to put the label Vetically down the button instead of across it. When I use the following code to rotate the label [workPackageButton.titleLabel setTransform:CGAffineTransformMakeRotation(M_PI / 2)]; It rotates the label but the length seems to be constrained by the original width, so I get the ... abreviation in the middle. Is there an easy way round this?

  • How do I superimpose one bitmap image on another in GDI+?

    - by Old Man
    Using GDI+ I've made a heatmap bmp and I'd like to superimpose it on top of my bmp map. I've saved the two bmps to disk, and they look good, I just need a way to put them together. Is there any way to do this, perhaps using the Graphics object? How is transparency/alpa involved? I'm very new to GDI programming so please be as specific as possible.

  • SQL Server Service Broker Service Disappearing (Automatically Deleted)?

    - by mwigdahl
    I've implemented a messaging system over SQL Server Service Broker. It is working great, with the sole exception that every once in a while (maybe once per week per server) my initiator service just vanishes without a trace. The corresponding queue is still there, but the service is missing. Obviously this causes problems in my system. It's a simple matter to recreate the service by hand, but I'm confused as to what might cause this behavior. I understand that automatic poison message handling causes queues to be disabled, but I don't see anything that indicates services can be disabled or deleted automatically. When this happens, I usually have a large backlog of messages in multiple application queues, but nothing extreme. Total message backlog is around 200,000. Does anyone know what might be happening here?

  • JAVA-I don't want clicking on my app make other apps lose focus

    - by Auxiliary
    Wow, what a stupid question you might say. But is it possible? I have a mouse move event in a Jpanel and it works even when the application is not in focus, now can I have something like that for the clicking event or something similar. And most importantly I don't want other apps (even something like the main menu) to lose focus when i click on my app. I was the system's event queue but i'm not sure where that would lead me to. Thanks in advance.

  • How to perform an NTLM challenge on the iPhone.

    - by toast
    I'm trying to access some web services in an iPhone application. If I GET to the .asmx page, I authenticate and get the WSDL as expected. However, if I POST to the .asmx page, setting the SOAPAction, Content-Type, Content-Length, and HTTPBody, I just keep getting didReceiveAuthenticationChallenge messages. Additionally, I'm trying to POST to IIS using Integrated Windows Authentication (IWA), which means I'm trying to negotiate an NTLM challenge.

  • Help with regex pulling XML data from response body in PHP

    - by spdaly
    I am working on a project that pulls data from JMS queue using PHP and Zend Framework. The HTTP client response is below. All I need is the XML string. I came up with /(.*)<\/RequestDetails/gs which tests ok on http://gskinner.com/RegExr/ but the preg_match call is returning an empty matches array. I'm going to continue to hunt around for a pattern, but thought I would post here as well. Thanks to all who read, etc... Steve UPDATE: I can't get the code to paste correctly. Here's a link to a pastbin: http://pastebin.com/rQxzcfSg

  • Find out how much storage a row is taking up in the database

    - by Vaccano
    Is there a way to find out how much space (on disk) a row in my database takes up? I would love to see it for SQL Server CE, but failing that SQL Server 2008 works (I am storing about the same data in both). The reason I ask is that I have a Image column in my SQL Server CE db (it is a varbinary[max] in the SQL 2008 db) and I need to know now many rows I can store before I max out the memory on my device.

  • Having a fork match the original repo when the original master branch can't be merged in?

    - by a2h
    The related questions that SO offer me only answer simple cases that can be solved with a pull - however, that won't work for my case. There's a repository I've forked, with just a master branch, and I've forked it, and I've worked in both my master, and a new branch of my own, rw-style. The owner of the forked repository's committed some of my changes but not others; the black dots on the top right below represent commits from both my master and rw-style branches. I'm aware using the fork queue is not a good idea, so I'm staying away from it. Using git pull does work, but it creates a conflict that I would then need to resolve, and it also results in duplicate history for my master branch, and that doesn't look particularly pretty. I don't know any other solutions right now, so I'm currently considering just creating a patch from two commits that I haven't yet pushed, deleting my fork, creating it again from the original, and then applying my patches on top of it. Is that the only solution?

  • Centering fonts in VB6

    - by James Musser
    How do you determine the length of a string of text in Arial Bold font, and then center it in VB6? If not here, can you point me in a direction where I might be able to find this information? We're not using a "label" or "picture box" do print the text to the screen. We are sizing the text on the fly, and allowing the user to scale the size of our application to their liking. We write the text to screen using code.

  • TreeView Control unexpected event behavior

    - by ProgNet
    Hi all, In the MSDN is writen about TreeNode that: "By default, a node is in selection mode." "To put a node into selection mode, set the node's NavigateUrl property to an empty string." "When a node is in selection mode, use the SelectAction property to specify which event or events are raised when a node is selected." "Setting TreeNodeSelectAction value TreeNodeSelectAction.Select Raises the SelectedNodeChanged event when a node is selected." Please see TreeNode Here is the problem and possibly a bug in the control: When I set the TreeNode object PopulateOnDemand value to true and call the Collapse() function on that node. Then the TreeNodeExpanded event is raised in addition to the SelectedNodeChanged event. This is in complate contradiction to what is writen in the MSDN. According to the MSDN this sould happen only if TreeNodeSelectAction Property is set to TreeNodeSelectAction.SelectExpand value. Does some know whats the cause for that? Here is the code: <asp:TreeView ID="TreeView1" runat="server" AutoGenerateDataBindings="False" onselectednodechanged="TreeView1_SelectedNodeChanged" ontreenodepopulate="TreeView1_TreeNodePopulate"> </asp:TreeView> protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack) { string path = Server.MapPath("."); PopulateTopNodes(path); } } //MSDN : Occurs when a node with its PopulateOnDemand property set to true is expanded in //the TreeView control. protected void TreeView1_TreeNodePopulate(object sender, TreeNodeEventArgs e) { LoadChildNode(e.Node); } private void PopulateTopNodes(string pathToRootFolder) { DirectoryInfo dirInfo = new DirectoryInfo(pathToRootFolder); DirectoryInfo[] dirs = dirInfo.GetDirectories(); foreach (DirectoryInfo dir in dirs) { string relativePath = (dir.FullName).Replace(pathToRootFolderPrefix, ""); TreeNode folderNode = new TreeNode(dir.Name, relativePath); if (dir.GetDirectories().Length > 0) { folderNode.PopulateOnDemand = true; folderNode.Collapse(); } folderNode.NavigateUrl = ""; folderNode.SelectAction = TreeNodeSelectAction.SelectExpand; TreeView1.Nodes.Add(folderNode); } } private void LoadChildNode(TreeNode treeNode) { string d = treeNode.NavigateUrl; string action = treeNode.SelectAction.ToString(); string fullPath = Path.Combine(pathToRootFolderPrefix, treeNode.Value); DirectoryInfo dirInfo = new DirectoryInfo(fullPath); DirectoryInfo[] dirs = dirInfo.GetDirectories(); foreach (DirectoryInfo dir in dirs) { string relativePath = (dir.FullName).Replace(pathToRootFolderPrefix, ""); TreeNode folderNode = new TreeNode(dir.Name, relativePath); if(dir.GetDirectories().Length>0){ folderNode.PopulateOnDemand = true; folderNode.Collapse(); } folderNode.NavigateUrl = ""; folderNode.SelectAction = TreeNodeSelectAction.SelectExpand; treeNode.ChildNodes.Add(folderNode); } } //MSDN:Occurs when a node is selected in the TreeView control. protected void TreeView1_SelectedNodeChanged(object sender, EventArgs e) { } Thanks

  • UIEvent timestamp

    - by skajam66
    When handling a UIButton touch, you are given a UIEvent object. The UIEvent object has a timestamp which the Apple documentation states as being "the time that the event was created" (UIEvent Class Reference). In the documentation on the Main Event Loop, it states that: "The application object obtains the topmost object in the event queue, converts it to an event object (UIEvent) ..." Does [UIEvent timestamp] refer to the time at which the UIEvent object is created (i.e. after processing the touch event off of the main run loop and hance not remotely real-time) or does it refer to the time that the underlying touch object was created (and hence as close as possible to representing the actual time of the user touch9?

  • Boxy Submit Form

    - by jornbjorndalen
    I am using the boxy jQuery plugin in my page to display a form on a clickEvent for the fullCalendar plugin. It is working all right , the only problem I have is that the form in boxy brings up the confirmation dialog the first time the dialog is opened and when the user clicks "Ok" it submits the form a second time which generates 2 events on my calendar and 2 entries in my database. My code looks like this inside fullCalendar: dayClick: function(date, allDay, jsEvent, view) { var day=""+date.getDate(); if(day.length==1){ day="0"+day; } var year=date.getFullYear(); var month=date.getMonth()+1; var month=""+month; if(month.length==1){ month="0"+month; } var defaultdate=""+year+"-"+month+"-"+day+" 00:00:00"; var ele = document.getElementById("myform"); new Boxy(ele,{title: "Add Task", modal: true}); document.getElementById("title").value=""; document.getElementById("description").value=""; document.getElementById("startdate").value=""+defaultdate; document.getElementById("enddate").value=""+defaultdate; } I also use validators on the forms fields: $.validator.addMethod( "datetime", function(value, element) { // put your own logic here, this is just a (crappy) example return value.match(/^([0-9]{4})-([0-1][0-9])-([0-3][0-9])\s([0-1][0-9]|[2][0-3]):([0-5][0-9]):([0-5][0-9])$/); }, "Please enter a date in the format YYYY-mm-dd hh:MM:ss" ); var validator=$("#myform").validate({ onsubmit:true, rules: { title: { required: true }, startdate: { required: true, datetime: true }, enddate: { required: true, datetime: true } }, submitHandler: function(form) { //this function renders a new event and makes a call to a php script that inserts it into the db addTask(form); } }); And the form looks like this: <form id ='myform'> <table border='1' width='100%'> <tr><td align='right'>Title:</td><td align='left'><input id='title' name='title' size='30'/></td></tr> <tr><td align='right'>Description:</td><td align='left'><textarea id='description' name='description' rows='4' cols='30'></textarea></td></tr> <tr><td align='right'>Start Date:</td><td align='left'><input id='startdate' name='startdate' size='30'/></td></tr> <tr><td align='right'>End Date:</td><td align='left'><input id='enddate' name='enddate' size='30' /></td></tr> <tr><td colspan='2' align='right'><input type='submit' value='Add' /></td></tr> </table> </form>

  • SQL Server 2008 - Query takes forever to finish even though work is actually done

    - by Brian
    Running the following simple query in SSMS: UPDATE tblEntityAddress SET strPostCode= REPLACE(strPostCode,' ','') The update to the data (at least in memory) is complete in under a minute. I verified this by performing another query with transaction isolation level read uncommitted. The update query, however, continues to run for another 30 minutes. What is the issue here? Is this caused by a delay to write to disk? TIA

    Is there a gem/example_code that allows to work with regexps? I am not looking for what a regexp can do, but what can be done to a Regexp object. For example: r = Regexp.new(...) r.min_length => the minimum length of a matching string r = Regexp.new("car(less)?") r.min_length => 3 for the string "car" Thanks!

  • How can an SQL query return data from multiple tables

    - by Fluffeh
    I would like to know how to get data from multiple tables in my database, what types of methods are there to do this, what are joins and unions and how are they different from one another? When should I use each one compared to the others? I am planning to use this in my (for example - PHP) application, but don't want to run multiple queries against the database, what options do I have to get data from multiple tables in a single query? Note: I am writing this as I would like to be able to link to a well written guide on the numerous questions that I constantly come across in the PHP queue, so I can link to this for further detail when I post an answer. The answers cover off the following: Part 1 - Joins and Unions Part 2 - Subqueries Part 3 - Tricks and Efficient Code
