  • How to align MDIChild on left?

    - by lyborko
    Hi, I am trying hard to align MDIChild form to the left of the parent MDIForm setting Align:=alLeft at design time. Aparently aligned MDIChild is higher than parents client area (I do not know why), thats why vertical scrollbar appears on parent form. The problem is, that I want this form create dynamicaly; putting vertical Splitter between these MDIchild forms, in order to size them by mouse. But when I create Splitter it aligns itself totaly on the left, as if MDIChild form was not aligned (alLeft) at all. I set MDIChild parameters to: Align:=alLeft; Windowstate:=wsNormal; Borderstyle:=bsSizable; Does anybody solved this problem before? thanx a lot P.S Delphi 7, Win XP

  • PHP, include with parameters

    - by chris
    hi! I have a PHP-file which will be called from a form. So it gets parameters over $_GET. Now I need the exact same functionality of this file, but not in such a form-call. I will include it in normal code with fixed parameters (which normally come from the form). So my file can work with the form AND without it. I know only the way with include and setting the $_GET in front of it. But I am not sure this is the most elegant way (I dont like the idea of setting things like $_GET). any other ways of doing this? br, chris

  • Codeigniter: Submitting Forms

    - by Kevin Brown
    How do I submit a form that can do two different things based on the URI? For example, if the URI contains a string "new" the form will submit differently than it would if "new" were not in the URI. I'm having trouble implementing this, as when a form is submitted, it takes the URI of whatever "form_open" says.

  • JSF + PrimeFaces: `update` attribute does not update component

    - by Harry Pham
    Here is my layout <div id="mainPanel"> <div id="padding"> <h:outputText id="text" value="Personal Feed" rendered="#{Profile.renderComment}"/> </div> <div id="right"> <h:form> <p:commandButton value="Update" actionListener="#{bean.toggleComment}" update="text" /> </h:form> </div> </div> When I click the link Update, which suppose to toggle the renderComment boolean on and off, but it does not toggle the display of the text Personal Feed. Now if I put a form around the h:outputText, and instead update the form instead, then it work. Why is that?

  • Django database caching

    - by hekevintran
    I have a Django form that uses an integer field to lookup a model object by its primary key. The form has a save() method that uses the model object referred to by the integer field. The model's manager's get() method is called twice, once in the clean method and once in the save() method: class MyForm(forms.Form): id_a = fields.IntegerField() def clean_id_a(user_id): id_a = self.cleaned_data['id_a'] try: # here is the first call to get MyModel.objects.get(id=id_a) except User.DoesNotExist: raise ValidationError('Object does not exist') def save(self): id_a = self.cleaned_data['id_a'] # here is the second call to get my_model_object = MyModel.objects.get(id=id_a) # do other stuff I wasn't sure whether this hits the database two times or one time so I returned the object itself in the clean method so that I could avoid a second get() call. Does calling get() hit the database two times? Or is the object cached in the thread? class MyForm(forms.Form): id_a = fields.IntegerField() def clean_id_a(user_id): id_a = self.cleaned_data['id_a'] try: # here is my workaround return MyModel.objects.get(id=id_a) except User.DoesNotExist: raise ValidationError('Object does not exist') def save(self): # looking up the cleaned value returns the model object my_model_object = self.cleaned_data['id_a'] # do other stuff

  • Why does my custom component raise AVs in the IDE?

    - by Mason Wheeler
    I'm trying to write a simple component that will allow you to embed one or more SDL rendering surfaces on a Delphi window, using the SDL 1.3 APIs. It will compile and install just fine, but when I try to use the component in the form designer, it raises AVs whenever I try to access its properties in the object inspector, save the form, or delete the component, and placing one on a form then trying to run gives a linker error: it apparently can't read the DFM properly for whatever reason. The DLL can be found at http://www.libsdl.org/tmp/SDL-1.3-dll.zip and the source code to my component can be downloaded here. SDL.pas is a JEDI-SDL header file; the rest is my own code. I don't see any reason for this to raise AVs in the form designer. If I dynamically create the control at runtime I don't have any stability issues. Can anyone take a look at this and maybe provide some feedback that might help me clear it up?

  • Populating fields, input types etc using JSON

    - by Franco
    I have a form that works as follows.. Server request builds XML of the data on server side and sends xml, XSL stylesheet then transforms the XML data into the plain html page distributing the data to the relevant/desired locations of the form on the page. Person can view page and edit the populated form, submit back to DB. I think JSON is more suitable for this from what I have read. The form itself is split into 3 areas, for me this is 3 maps/associative arrays etc each with a name related to the id of an input element etc. The problem for me comes with having the JSON sent to the page, what should I do with it next in order to achieve the same result as I currently get with XML and XSL. Thanks.

  • SQL efficiency argument, add a column or solvable by query?

    - by theTurk
    I am a recent college graduate and a new hire for software development. Things have been a little slow lately so I was given a db task. My db skills are limited to pet projects with Rails and Django. So, I was a little surprised with my latest task. I have been asked by my manager to subclass Person with a 'Parent' table and add a reference to their custodian in the Person table. This is to facilitate going from Parent to Form when the custodian, not the Parent, is the FormContact. Here is a simplified, mock structure of a sql-db I am working with. I would have drawn the relationship tables if I had access to Visio. We have a table 'Person' and we have a table 'Form'. There is a table, 'FormContact', that relates a Person to a Form, not all Persons are related to a Form. There is a relationship table for Person to Person relationships (Employer, Parent, etc.) I've asked, "Why this couldn't be handled by a query?" Response, Inefficient. (Really!?!) So, I ask, "Why not have a reference to the Form? That would be more efficient since you wouldn't be querying the FormContacts table with the reference from child/custodian." Response, this would essentially make the Parent is a FormContact. (Fair enough.) I went ahead an wrote a query to get from non-FormContact Parent to Form, and tested on the production server. The response time was instantaneous. *SOME_VALUE* is the Parent's fk ID. SELECT FormID FROM FormContact WHERE FormContact.ContactID IN (SELECT SourceContactID FROM ContactRelationship WHERE (ContactRelationship.RelatedContactID = *SOME_VALUE*) AND (ContactRelationship.Relationship = 'Parent')); If I am right, "This is an unnecessary change." What should I do, defend my position or should I concede to the managers request? If I am wrong. What is my error? Is there a better solution than the manager's?

  • jQuery Validate Plugin overwrite my select onChange postback

    - by C.Hoffmann
    Hi, I'm creating this form (.net) where i have a select with a postback, that will trigger a action depending on which option i select. I'm trying to use the jQuery Validate Plugin (plugin website) to validate my form. My problem is, when i validate the form, and my select is marked as invalid, the validation plugin overwrite it's onChange method to make it unmark when i change the value, the thing is that it's deleting my __dopostback from the onchange, making the form 'useless'. Is there a way to the plugin validate my selects without deleting my postback action from the onchange?

  • Targeted Simplify in Mathematica

    - by Timo
    I generate very long and complex analytic expressions of the general form: (...something not so complex...)(...ditto...)(...ditto...)...lots... When I try to use Simplify, Mathematica grinds to a halt, I am assuming due to the fact that it tries to expand the brackets and or simplify across different brackets. The brackets, while containing long expressions, are easily simplified by Mathematica on their own. Is there some way I can limit the scope of Simplify to a single bracket at a time? Edit: Some additional info and progress. So using the advice from you guys I have now started using something in the vein of In[1]:= trouble = Log[(x + I y) (x - I y) + Sqrt[(a + I b) (a - I b)]]; In[2]:= Replace[trouble, form_ /; (Head[form] == Times) :> Simplify[form],{3}] Out[2]= Log[Sqrt[a^2 + b^2] + (x - I y) (x + I y)] Changing Times to an appropriate head like Plus or Power makes it possible to target the simplification quite accurately. The problem / question that remains, though, is the following: Simplify will still descend deeper than the level specified to Replace, e.g. In[3]:= Replace[trouble, form_ /; (Head[form] == Plus) :> Simplify[form], {1}] Out[3]= Log[Sqrt[a^2 + b^2] + x^2 + y^2] simplifies the square root as well. My plan was to iteratively use Replace from the bottom up one level at a time, but this clearly will result in vast amount of repeated work by Simplify and ultimately result in the exact same bogging down of Mathematica I experienced in the outset. Is there a way to restrict Simplify to a certain level(s)? I realize that this sort of restriction may not produce optimal results, but the idea here is getting something that is "good enough".

  • Sharepoint List redirect with new id

    - by TheRealQuagmire
    I have a list within Sharepoint, using a custom new form i have added a custom list form control ("New item form" for the list) and changed the SaveButton to a standard input HTML button, and added an 'onclick' event that is as follows: onclick="javascript: {ddwrt:GenFireServerEvent('__commit;__redirect={NewFormWizard2.aspx?id=}')}" this works as in saves the data and redirects to the NewFormWizard2.aspx?id= page. the question is how do i get the ID of the created item to be passed to the redirected page? thus once the form is completed it would redirect to NewFormWizard2.aspx?id=23 Thanks in advanced.

  • GRUB is not Booting Correctly

    - by msknapp
    I have a PC with three hard disks. Windows 7 is installed on the first, Ubuntu 14.04 is installed on the third. After I re-booted, it went straight to Windows 7. So I tried explicitly telling my PC to boot using the third hard disk, but that just takes me to the grub rescue prompt. I followed Scott Severence's instructions here to try and recover. Essentially, I updated grub, reinstalled grub, and then updated it again. After re-booting, absolutely nothing had changed. So instead I tried using the boot-repair tool. In the past it had failed for me, saying that I had programs running and it could not unmount drives, when I was running nothing. I never figured out how to solve that problem, but it went away when I bought another hard drive and used that for my Ubuntu installation, I don't know why. In any case, I ran the boot-repair tool and this time it said it was successful. First time for everything right? I re-booted, only to be taken straight to the grub rescue prompt. So I changed my BIOS settings to use the third hard disk for boot start up. That is the same hard drive where I have Ubuntu and grub installed, and the same one that the grub-repair tool told me to use. It still took me straight to the grub rescue prompt. So I went from not being able to boot Ubuntu, to not being able to boot either OS installed on my system. Thanks boot-repair! Boot repair gave me this URL for future troubleshooting: http://paste.ubuntu.com/8131669 When I try to boot from the third hard disk, this is my console: Loading Operating System ... error: attempt to read or write outside of disk 'hd0'. Entering rescue mode... grub rescue> grub rescue> set cmdpath=(hd0) prefix=(hd0,gpt2)/boot/grub root=hd0,gpt2 grub rescue> ls (hd0) (hd0,gpt3) (hd0,gpt2) (hd0,gpt1) (hd1) (hd2) (hd2,gpt2) (hd2,gpt1) (hd3) Those values look correct to me. I have also experimented with changing some of those values, but 'insmod normal' always throws the same error. Somebody please tell me how to fix this. I have tried everything, reinstalling grub, and running boot-repair. =========================== Update: I think the problem might be that the ubuntu installer did not partition my hard disk correctly. I booted from live USB and then launched gparted and looked at how it partitioned things. This is what gparted says: Partition, File System, Size, Used, Unused, Flags /dev/sda1 (!), unknown, 1.00 MiB, ---, ---, bios_grub /dev/sda2, ext4, 2.71 TiB, 47.30 GiB, 2.67 TiB, /dev/sda3, linux-swap, 16.00 GiB, 0.00 B, 16.00 GiB, So that first line looks problematic. It is supposed to be the /boot partition. However, it was given only 1 MiB? I am assuming that MiB is actually supposed to mean megabyte, no idea why that 'i' is there. It also says the file system is unknown. I read the answer by andrew here, and he says he had to do a custom install, explicitly configuring the boot partition. So I think that maybe Ubuntu's installer has a bug in it, where it does not set up the boot partition correctly if you are not installing on the first hard disk in your computer. I am going to try reinstalling with a custom partition scheme. I read elsewhere (askubuntu won't let me post another link) that I don't even need a /boot partition any more. So instead of following Andrew's instructions ver batim, I'm first going to try having just two partitions: one for /, and another for my 16GB swap space. Both as primary partitions. The first will be formatted as ext4. If that doesn't work, I may try again using /boot. ======================== So I did my custom install with no /boot partition, and it did not work. When I rebooted, I had an error message saying that some address did not exist. So for the hundredth time, I booted from the live USB, and ran boot-repair. Now I get this message GPT detected. Please create a BIOS-Boot partition (>1MB, unformatted filesystem, bios_grub flag). This can be performed via tools such as Gparted. Then try again. I feel like I'm running in circles and nobody will help me.

  • Issue on dojo onlick event on html button

    - by Cuong Le
    I am a new kid with dojo, I got weird issue which I take lots of time and have not yet found out, assume I have 4 buttons: <button id="btnMoveFirst" data-dojo-type="dijit.form.Button" iconclass="plusIcon"> &lt; &lt;</button> <button id="btnMovePrev" data-dojo-type="dijit.form.Button" iconclass="plusIcon"> &lt;</button> <button id="btnMoveNext" data-dojo-type="dijit.form.Button" iconclass="plusIcon"> &gt;</button> <button id="btnMoveLast" data-dojo-type="dijit.form.Button" iconclass="plusIcon"> &gt; &gt;</button> And use dojo with event onclick as below: dojo.connect(dijit.registry.byId('btnMoveFirst'), "onclick", function(evt){ alert('test1'); }); dojo.connect(dijit.registry.byId('btnMovePrev'), "onclick", function(evt){ alert('test2'); }); dojo.connect(dijit.registry.byId('btnMoveNext'), "onclick", function(evt){ alert('test3'); }); dojo.connect(dijit.registry.byId('btnMoveLast'), "onclick", function(evt){ alert('test4'); }); But when I click any one of 4 buttons, or even any button in form, I got 4 alerts instead of only correct one. Does anyone know this?

  • Testing Broadcasting and receiving messages

    - by Avik
    Guys am having some difficulty figuring this out: I am trying to test whether the code(in c#) to broadcast a message and receiving the message works: The code to send the datagram(in this case its the hostname) is: public partial class Form1 : Form { String hostName; byte[] hostBuffer = new byte[1024]; public Form1() { InitializeComponent(); StartNotification(); } public void StartNotification() { IPEndPoint notifyIP = new IPEndPoint(IPAddress.Broadcast, 6000); hostName = Dns.GetHostName(); hostBuffer = Encoding.ASCII.GetBytes(hostName); UdpClient newUdpClient = new UdpClient(); newUdpClient.Send(hostBuffer, hostBuffer.Length, notifyIP); } } And the code to receive the datagram is: public partial class Form1 : Form { byte[] receivedNotification = new byte[1024]; String notificationReceived; StringBuilder listBox; UdpClient udpServer; IPEndPoint remoteEndPoint; public Form1() { InitializeComponent(); udpServer = new UdpClient(new IPEndPoint(IPAddress.Any, 1234)); remoteEndPoint=null; startUdpListener1(); } public void startUdpListener1() { receivedNotification = udpServer.Receive(ref remoteEndPoint); notificationReceived = Encoding.ASCII.GetString(receivedNotification); listBox = new StringBuilder(this.listBox1.Text); listBox.AppendLine(notificationReceived); this.listBox1.Items.Add(listBox.ToString()); } } For the reception of the code I have a form that has only a listbox(listBox1). The problem here is that when i execute the code to receive, the program runs but the form isnt visible. However when I comment the function call( startUdpListener1() ), the purpose isnt served but the form is visible. Whats going wrong?

  • Delphi: How to diagnose sluggish UI?

    - by Ian Boyd
    i have a form, which you can pretend is laid out like Windows Explorer: panel on the left splitter client panel +------------+#+-----------------------+ | |#| | | |#| | | |#| | | |#| | | Left |#| Client | | |#| | | |#| | | |#| | | |#| | | |#| | +------------+#+-----------------------+ ^ | +----splitter The the left and client area panels are each rich with controls. The problem is that using the splitter is very sluggish. i would expect that a modern 2 GHz computer can re-display the form as fast as a human can push the mouse around. But that's definitely not the case, and it takes about 200-300 ms before the form is fully re-adjusted. The form has about 100 visual controls on it, no code, or custom controls. How do i go about tracing who's the cause of the sluggishness?

  • How to get MySQL database to appear on index.php

    - by Teddy Truong
    Hi, I have a submission form on my website (index.php) and I have the data(user submissions) being stored into a MySQL database. Right now, I have the user submitting a post and then the page directs them to an update.php which shows what they inputed. However, I want all of the data in the database in MySQL to be shown on the index.php. It's a lot like a comment system. User submits a post... and sees their post above the other submitted posts all on the same page. I think I'm missing AJAX... ? Here is the code for index.php <div align="center"> <p>&nbsp;</p> <h2 align="center" class="Title"><em><strong>REDACTED</strong></em></h2> <form id="form1" name="form1" method="post" action="update.php"> <hr /> <label><br /> <form action="update.php" method="post"> REDACTED: <input type="text" name="text" /> <input type="submit" /> </form> </label> </form> </div> On update.php I have this: ?php $text = $_POST['text']; $myString = "REDACTED"; mysql_connect ("db----.net", "-----3", "------------") or die ('Error: ' . mysql_error()); mysql_select_db ("-----------"); $query="INSERT INTO TextArea (ID, text) VALUES ('NULL', '".$text."')"; mysql_query($query) or die ('Error updating database'); echo " $myString "," $text "; ?> Thanks a lot!

  • Integrated ads in phone apps - how to avoid wasting battery?

    - by Jarede
    Considering the PCWorld review that came out in March: Free Android Apps Packed with Ads are Major Battery Drains ...Researchers from Purdue University in collaboration with Microsoft claim that third-party advertising in free smartphone apps can be responsible for as much as 65 percent to 75 percent of an app's energy consumption... Is there a best practice for integrating advert support into mobile applications, so as to not drain user battery too much? ...When you fire up Angry Birds on your Android phone, the researchers found that the core gaming component only consumes about 18 percent of total app energy. The biggest battery suck comes from the software powering third-party ads and analytics accounting for 45 percent of total app energy, according to the study... Has anyone invoked better ways of keeping away from the "3G Tail", as the report puts it? Is it better/possible to download a large set of adverts that are cached for a few hours, and using them to populate your ad space, to avoid constant use of the Wi-Fi/3G radios? Are there any best practices for the inclusion of adverts in mobile apps?
