  • Is it possible to make a TListView search by the caption of a different column in Delphi?

    - by James
    Hi, When you set the Caption of a TListItem it seems to always set the Text for the first column in the row. When you start typing in the ListView it will search & select the closest match based on the caption of the first column. I have a situation where I need the caption of the first row to be empty, but still need the search functionality to work as normal (in this case the data I would be searching for may be in the 2nd/3rd column). Is this possible without using any 3rd party controls?

  • Saving variables (not sessions)

    - by james.bcn
    This may be a silly question, but how do I save variables that are not specific to a particular session. An simple example of why you might want to do this would be a visitor counter - a number that increases by one each time someone visits a web page (note - I'm not actually doing that, my application is different, but that is the functionality I need). The only ways I can think of doing this are either writing the variables to a file, or putting the variables into a database. Both seem a bit inelegant. Is there a better way to to this kind of thing?

  • Is it poor practice to identify objects via an enumeration property, instead of using GetType()?

    - by James
    I have a collection of objects that all implement one (custom) interface: IAuditEvent. Each object can be stored in a database and a unique numeric id is used for each object type. The method that stores the objects loops around a List<IAuditEvent>, so it needs to know the specific type of each object in order to store the correct numeric id. Is it poor practice to have an enumeration property on IAuditEvent so that each object can identify itself with a unique enumeration value? I can see that the simplest solution would be to write a method that translates a Type into an integer, but what if I need an enumeration of audit events for another purpose? Would it still be wrong to have my enumeration property on IAuditEvent?

  • Decoding base64 php file

    - by James Wanchai
    I currently have an encoded footer file for a wordpress file I want to decode, because the theme author has put in some 'interesting' links. Don't get me wrong, I'm very happy to link back to the author, but gambling sites aren't really what I want!

  • How can I convert my Stream (image data) back into a file

    - by James Hay
    I have a WCF restful service that I'm trying to upload an image to. I have a very basic metod that accepts a stream as it's only parameter and is defined in the contract as: [OperationContract] [WebInvoke(UriTemplate = "ReviewImage", BodyStyle = WebMessageBodyStyle.Bare, Method = "POST")] ReviewImage UploadImage(Stream data); I'm actually consuming this service from flash (which is fairly inconsequntial) which selects a file from the file system and uploads it through the service url. It all works seems to work, adding a breakpoint to the UploadImage method breaks as expected. If I wanted to save this file back to disk, is it just a case of reading this Stream object into a FileStream object that creates the file somewhere? A bit like the this? When i do actually do this the file can not be opened as an image. I'm sure i'm missing a key piece of knowledge here. Does my stream actually contain just the image bytes or does it contain more than that?

  • Is there a way to redirect ONLY stderr to stdout (not combine the two) so it can be piped to other programs

    - by James K
    I'm working in a Windows CMD.EXE environment and would like to change the output of stdout to match that of stderr so that I can pipe error messages to other programs without the intermediary of a file. I'm aware of the 2>&1 notation, but that combines stdout and stderr into a single stream. What I'm thinking of would be something like this: program.exe 2>&1 | find " " But that combines stdout and stderr just like: program.exe | find " " 2>&1 I realize that I could do... program 2>file type file | find " " del file But this does not have the flexibility and power of a program | find " " sort of notation. Doing this requires that program has finished with it's output before that output can be processed.

  • How to "scan" a website (or page) for info, and bring it into my program?

    - by James
    Well, I'm pretty much trying to figure out how to pull information from a webpage, and bring it into my program (in Java). For example, if I know the exact page I want info from, for the sake of simplicity a Best Buy item page, how would I get the appropriate info I need off of that page? Like the title, price, description? What would this process even be called? I have no idea were to even begin researching this.

  • Stop a user directly accesing a page

    - by James Jeffery
    I have a page called create.php. It receives post variables and sets up accounts. I don't want that page to be accessible by a user. What's the conventional way of achieving this? I think I remember reading something about including a page with a CONSTANT. If the CONSTANT is not present the page has been accessed directly. I think Wordpress also do it.

  • How do submit an object to a struts2 action using jQuery?

    - by James Drinkard
    I have an object that I'm populating from a selection off a table row that a user selects. I have a jQuery function that captures the click event and a hidden form field populates an id I need. However, I'm not sure as to the proper way to send off that object to a struts2 action? I tried using this: $(function() { $('#tbl tr').click(function() { var id = $(this).closest('tr').find('input:hidden').val(); var page = "<s:url action='update/deleteInfo.action'/>?model.isDelete=true&model.info.id=id"; console.log(page); window.location.href=(page); }); }); The model object has an isDelete boolean variable and the model has a nested info object that has an id variable with getter/setters. However, when I send this across, the model object isn't populated with these entries. Is there a way to do this or a better way than the url tag?

  • Using .htaccess to change my website URLs

    - by James P
    I have some pages organised like this: http://localhost/index.html http://localhost/download.html http://localhost/contact.html And I need them changed to suit the following URL structure: http://localhost/ http://localhost/download http://localhost/contact Without making sub directories and putting in pages as index.html. As far as I know .htaccess can be used for this, but I have no idea what I need to add to my .htaccess file to make this work. Can anyone provide some help? Thanks.

  • Questions about "sets"

    - by James
    I have a test tomorrow that I am revising for and the lecturer has supplied some sample questions with no answers. I was hoping I could get some help with a couple of them. I've written what I think the answer is for them. 1. What is the type of the set {1, 2, 3}? integer/number 2. What is the type of the set {{1}, {2}, {3}}? integer/number (unsure what putting each number in {} does?) 3. What is the type of the set {{1}, {2}, {3}, empty}? integer/number 4. What is the type of the set {1, {2}, 3}? — is it well typed? integer/number 5. What is the type of the set {1, 2, john}? — is it well typed? unsure for a mixed set. Taking a complete guess of void or empty. Any help will be much appreciated.

  • Resized XIB still full size

    - by James
    Building an iPad app. I have a button on my main view that I want to launch a help window. The help window is fairly involved and has its own xib/controller. I resized the help window's XIB and saved it. I instantiated it and added it to the application controller's views as a modal. For some reason this window is still taking up the entire screen. What I really want to do is have a "view" that's maybe 70% of the width and height that lays over the normal view as a modal. How is this accomplished normally? I want it to require that they hit a button to close it. Thanks

  • How can I dynamically resize the jQuery Colorbox plugin?

    - by James Skidmore
    The AJAX content loaded in a Colorbox has some JavaScript included that resizes things within the content. Colorbox determines its sizing based on the sizes before all of the AJAX happens. How can I make the Colorbox resize after the content has been loaded? Here is a link where someone said that you can call colorbox() again after it's been loaded, but I can't figure out how to do that: http://groups.google.com/group/colorbox/browse_thread/thread/535d21c69e9006b0

  • Why isn't this working - using :not() with an event handler

    - by james emanon
    I seem to have another issue that I am not conquering. Real simple premise. I have a mousedown event, and basically IF one particular element on the page is clicked, I want nothing to happen, else I want hide() some div. $(function(){ $("document :not(#_ignorelement)").mousedown(function(event){ if($('#_hidethiselement').length){ $('#_hidethiselement').hide(); } }) }) That is not working at all. I also tried the following: $(document).not($("#_ignorelement")).mousedown(function(event){ $(document).not("_ignorelement").mousedown(function(event){ IF I can solve that, curious how I would actually have ":not" encompass the parent div, like so: $().not("_ignoreelement").parent().closest('div').mousedown(function Because the element "_ignorelement" is an anchor tag that is in a div. Wonder how I can use the parent div perhaps, instead of the anchor tag. Anyways, any help would be appreciated.

  • Performing an operation based on values within an array

    - by James W.
    I'm trying to figure out how to do operations based on values in an array. The values are taken from a string and inserted into the array e.g num = TextBox.Text.Split(' '); results = Convert.ToDouble(num[0]); for (int i = 0; i < num.Length - 1; i++) { if (num[i] == "+") { results += Convert.ToDouble(num[i++]); } ... } So based on this, let's say the TextBox string value was "1 + 2". So the array would be: ------------- | 1 | + | 2 | ------------- 0 1 2 (indexes) The part I'm having trouble with is Convert.ToDouble(num[i++]).. I've tried num[1] + 1, num[i + 1], etc I'm trying to figure out how to get it to perform the operation based on the first value and the value in the index after the operator. Which is the correct way to do something like this?

  • Surface Review from Canadian Guy Who Didn&rsquo;t Go To Build

    - by D'Arcy Lussier
    I didn’t go to Build last week, opted to stay home and go trick-or-treating with my daughters instead. I had many friends that did go however, and I was able to catch up with James Chambers last night to hear about the conference and play with his Surface RT and Nokia 920 WP8 devices. I’ve been using Windows 8 for a while now, so I’m not going to comment on OS features – lots of posts out there on that already. Let me instead comment on the hardware itself. Size and Weight The size of the tablet was awesome. The Windows 8 tablet I’m using to reference this against is the one from Build 2011 (Samsung model) we received as well as my iPad. The Surface RT was taller and slightly heavier than the iPad, but smaller and lighter than the Samsung Win 8 tablet. I still don’t prefer the default wide-screen format, but the Surface RT is much more usable even when holding it by the long edge than the Samsung. Build Quality No issues with the build quality, it seemed very solid. But…y’know, people have been going on about how the Surface RT materials are so much better than the plastic feeling models Samsung and others put out. I didn’t really notice *that* much difference in that regard with the Surface RT. Interesting feature I didn’t expect – the Windows button on the device is touch-sensitive, not a mechanical one. I didn’t try video or anything, so I can’t comment on the media experience. The kickstand is a great feature, and the way the Surface RT connects to the combo case/keyboard touchcover is very slick while being incredibly simple. What About That Touch Cover Keyboard? So first, kudos to Microsoft on the touch cover! This thing was insanely responsive (including the trackpad) and really delivered on the thinness I was expecting. With that said, and remember this is with very limited use, I would probably go with the Type Cover instead of the Touch Cover. The difference is buttons. The Touch Cover doesn’t actually have “buttons” on the keyboard – hence why its a “touch” cover. You tap on a key to type it. James tells me after a while you get used to it and you can type very fast. For me, I just prefer the tactile feeling of a button being pressed/depressed. But still – typing on the touch case worked very well. Would I Buy One? So after playing with it, did I cry out in envy and rage that I wasn’t able to get one of these machines? Did I curse my decision to collect Halloween candy with my kids instead of being at Build getting hardware? Well – no. Even with the keyboard, the Surface RT is not a business laptop replacement device. While Office does come included, you can’t install any other applications outside of Windows Store Apps. This might be limiting depending on what other applications you need to have available on your computer. Surface RT is a great personal computing device, as long as you’re not already invested in a competing ecosystem. I’ve heard people make statements that they’re going to replace all the iPads in their homes with Surface tablets. In my home, that’s not feasible – my wife and daughters have amassed quite a collection of games via iTunes. We also buy all our music via iTunes as well, so even with the XBox streaming music service now available we’re still tied quite tightly to iTunes. So who is the Surface RT for? In my mind, if you’re looking for a solid, compact device that provides basic business functionality (read: email) or if you have someone that needs a very simple to use computer for email, web browsing, etc., then Surface RT is a great option. For me, I’m waiting on the Samsung Ativ Smart PC Pro and am curious to see what changes the Surface Pro will come with.
