  • Custom validatior in ASP.net

    - by DJPB
    Hi there. I'm working on an ASP.NET/C# app. I have 2 text boxes and I need to validate if the input text for both of them are not both null ex: if(string.IsNullOrEmpty(TextBox1.Text) && string.IsNullOrEmpty(TextBox2.Text) ) //FAIL!!! else // OK! that is, at least one txtBox has values I was planning on using a custom validator but it seems that the validation function only gets called when something is written on the textBox i'm using has the 'control to validate'. Now, that doesn't work for me since I want to show an error message when both text boxes are empty. Is there a way to make the validation function to be called with, for example a postback? Or is there any other better approach to this case than the custom validator? tks

  • Firefox released beta 9 for version 4

    - by anirudha
    Firefox yesterday released 9 beta of Firefox 4. now many plug-in work inside Firefox 4. How to get plugin work in Firefox 4 :- if you like any plug-in who you like to use but not worked in Firefox 4 go to developer site may be they work on them so it’s chance you can get the version who is in development from developer site. because many of plugin wait for a time period for testing or making same version for all plateform like linux or mac osX. How to work with stable and Beta version [standalone] sometime we fell that it’s time wasting because something we need the beta version can’t give. so you can use Firefox 3.6.13 or Firefox 4 both by a trick. you need to install them in other directory. when you trying to install another version beware because they also override the last installation directory so you need to choose the directory where you want to get another version manually.

  • Rails - Why is my custom validation being triggered for only a build command.

    - by adam
    I have a sentence and correction model with a has_one and belongs_to relationship respectively. For some reason when I do def create @sentence = Sentence.find(params[:sentence_id]) @correction = @sentence.build_correction(params[:correction]) a custom validation I wrote for Correction is being called at the build_correction point. the validation is below class Correction < ActiveRecord::Base attr_accessible :text, :sentence_id, :user_id belongs_to :sentence belongs_to :user validate :correction_is_different_than_sentence def correction_is_different_than_sentence errors.add(:text, "can't be the same as the original sentence.") if (text == self.sentence.text) end the problem is for some reason on validation the correction object doesn't have the sentence id set (despite I used the build_correction method) and so it complains "you have nil object .... while executing nil.text" in the if clause in the validation above. So my question is why is the validation occuring for a build command, i thought it only triggers on a create or update. And why isnt the sentence_id getting set?

  • Android changing colors with themes

    - by miannelle
    I am trying to provide user settable colors in my app. White text on black background and black text on white background. I have multiple layouts with many listviews, both standard and custom adapters. People have suggested using Themes, but I have had no luck changing the text colors across all layouts. Can anyone show me an actual Theme layout that can accomplish this? I can easily change the background colors using myscreen.setBackGroundColor(xx), but when I try to change the text with a theme, it also changes spinner text as well.

  • Menu bar and launcher missing in new installation of ubuntu 13.04

    - by Assimiz
    I have just installed ubuntu 13.04 on my ThinkPad laptop. I am missing the launcher and upper bar. I only found references to the same problem for upgrades, so I tried everything written here, here and here with no success. However, referring to the second link, I ran ccsm and found my Ubuntu Unity Plugin unchecked. Checking it required to also enable the OpenGL and so I did. But, apparently I am unable to enable the OpenGL. Trying to enable it manually...and the checkbox gets automatically unchecked after few seconds. Please help. Update: I have Intel graphics driver, maybe the problem is specifically with it?. I also tried running ccsm after logging using CTRL+ALT+F1 like given here. I was able to enable OpenGL and the Ubuntu Unity Plugin there, but still, no effect on my display, also after reboot.

  • String vectors not working as expected with newline and iterators? (C++)

    - by kevin
    I have a text file made of 3 lines: Line 1 Line 3 (Line 1, a blank line, and Line 3) vector<string> text; vector<string>::iterator it; ifstream file("test.txt"); string str; while (getline(file, str)) { if (str.length() == 0) str = "\n"; // since getline discards the newline character, replacing blank strings with newline text.push_back(str); } // while for (it=text.begin(); it < text.end(); it++) cout << (*it); Prints out: Line 1 Line 3 I'm not sure why the string with only a newline was not printed out. Any help would be appreciated. Thanks.

  • Posting form using javascript and json with nested objects

    - by Tim
    I have an html form that has the following structure: <input type="text" name="title" /> <input type="text" name="persons[0].name" /> <input type="text" name="persons[0].color" /> <input type="text" name="persons[1].name" /> <input type="text" name="persons[1].color" /> I would like to serialize this into the following json: { "title":"titlecontent", "persons":[ { "name":"person0name", "color":"red" }, { "name":"person1name", "color":"blue" } ] } Notice that the number of persons can vary from case to case. The structure of the html form can change, but the structure of the submitted json can't. How is this done the easiest?

  • preg_match and long strings

    - by aleluja
    Hi, This is the preg_match i am trying to use to find specific text in text file. if (preg_match($regexp,$textFile,$result) > 0) { echo "Found ".$result[0]; } else { echo "Not found"; } However, the result is always Found and nothing more. The result array is empty. Now i read that preg_match can't work with long strings. My text file is about 300KB so thats 300000 characters i guess. I am 100% sure that the searched string is in the text file, and the fact that preg_match function returns value above 0 means it found it, but it didn't place it into the result array somehow. So my question would be, how do i make it work? regexp would be /[specific text]\{(\d*)\}/ so, of course i want to be able to get the number in the parentheses.

  • Is this multi line if statement too complex?

    - by AndHeCodedIt
    I am validating input on a form and attempting to prompt the user of improper input(s) based on the combination of controls used. For example, I have 2 combo boxes and 3 text boxes. The 2 combo boxes must always have a value other than the first (default) value, but one of three, or two of three, or all text boxes can be filled to make the form valid. In one such scenario I have a 6 line if statement to try to make the test easily readable: if ((!String.Equals(ComboBoxA.SelectedValue.ToString(), DEFAULT_COMBO_A_CHOICE.ToString()) && !String.IsNullOrEmpty(TextBoxA.Text) && !String.Equals(ComboBoxB.SelectedValue.ToString(), DEFAULT_COMBO_B_CHOICE.ToString())) || (!String.IsNullOrEmpty(TextBoxB.Text) || !String.IsNullOrEmpty(TextBoxC.Text))) { //Do Some Validation } I have 2 questions: Should this type of if statement be avoided at all cost? Would it be better to enclose this test in another method? (This would be a good choice as this validation will happen in more than one scenario) Thanks for your input(s)!

  • Activate WPF command based on TextBox value

    - by zendar
    This is MVVM application. I have form and related view model class. There is TextBox, Button and ListBox on form. Button is bound to DelegateCommand that has CanExecute function. Idea is that user enters some data in text box, presses button and data is appended to list box. I would like to enable command (and button) when user enters correct data in TextBox. Things look like this now: CanExecute() contains code that checks if data in property bound to text box is correct. Text box is bound to property in view model UpdateSourceTrigger is set to PropertyChanged and property in view model is updated after each key user presses. Problem is that CanExecute() does not fire when user enters data in text box. It doesn't fire even when text box lose focus. How could I make this work?

  • CSS: Centering a floated block level element in IE6 (It almost works)

    - by Louis W
    I have a block level element which I am centering on the page. I have gotten it to work for all other browsers except IE6 where it ALMOST works. http://tinyurl.com/28sh9eq If I view the page in IE6 the red box is slightly off center of the pink one in IE. If I then resize the browser window it snaps into place where I want it. Uhhhhh.... yea.... what gives? How come resizing the window makes it work?

  • Breaking out of .emacs script

    - by prosseek
    I use two emacs (Aquamcs and text based emacs) on my Mac. I normally use text based emacs for just editing something, so I don't want to load anything with it. What I came up with is to have the checking code in .emacs to exit/break if it's text based emacs (darwin system but not aquamacs). (when (and (equal system-type 'darwin) (not (boundp 'aquamacs-version))) (exit) ??? (break) ???? ) It seems to work, but I don't know how to break out of .emacs. How to do that? ADDED I just wanted to speed up in loading text based emacs on my mac, and I thought about breaking out as a solution. Based on the helpful answers, I came up with the following code that runs .emacs only when it's not a text based emacs. (setq inhibit-splash-screen t) (unless (null window-system)

  • Bash intercepting wildcard in script

    - by MrRoth
    I am using Bash script to read line by line from a text file, which has special characters in it (regular expression). When I use echo "${SOME_VAR}" it does not display the text as is. I am familiar with Prevent * to be expanded in the bash script. How can I display and use the text as is? UPDATE The text (TSV) file holds tuples similar to (the last entry is a psql query) bathroom bathroom select name from photos where name ~* '\mbathroom((s)?|(''s)?)\M'; I am reading the CSV as follows: tail -n+2 text.file | while IFS=$'\t' read x y z do echo "${z}" done which gives the output select name from photos where name ~* 'mbathroom((s)?|(''s)?)M'); note that the '\' is missing

  • How to indicate 'missing' tags in XQuery?

    I have an XML file: $xml := <xml> <element> <text>blahblah</text> </element> <element> </element> <element> <text>blahblah</text> </element> </xml> I can use the query for $x in $xml/xml/element/text return string($x) This gives me a list blahblah blahblah with no indication that there is an element which has no element. What I'd like to do is use a query which, if there is no such element, returns, say "missing". How do I do this?

  • How to make a recursive onClickListener for expanding and collapsing?

    In plain english, I have a textview, and when I click on it I want it to expand, and when I click on it again, I want it to compress. How can I do this? I've tried the below, but it warns on the final line about expander might not be initialized on holderFinal.text.setOnClickListener(expander); So now the code: final View.OnClickListener expander = new View.OnClickListener() { @Override public void onClick(View v) { holderFinal.text.setText(textData); holderFinal.text.setOnClickListener( new View.OnClickListener() { @Override public void onClick(View v) { holderFinal.text.setText(shortText); holderFinal.text.setOnClickListener(expander); } }); } };

  • Function argument treated as undeclared

    I've prepared this simple example which is not working for me #include <stdio.h> #include <stdlib.h> FILE *fp; char filename[] = "damy.txt"; void echo (char[] text) { fp = fopen(filename, "a"); fwrite(text, 1, strlen(text), fp); fclose(fp); printf(text); } int main () { echo("foo bar"); return 0; } It's supposed to write both to command window and to file. However, this gives compilation error - the text used in echo() is not declared. Does c need another declaration of the variable?

  • regex to match specific html tags

    - by Rco8786
    I need to match html tags(the whole tag), based on the tag name. For script tags I have this: <script.+src=.+(\.js|\.axd).+(</script>|>) It correctly matches both tags in the following html: <script src="Scripts/JScript1.js" type="text/javascript" /> <script type="text/javascript" src="Scripts/JScript2.js" /> However, when I do link tags with the following: <link.+href=.+(\.css).+(</link>|>) It matches all of this at once(eg it returns one match containing both items): <link href="Stylesheets/StyleSheet1.css" rel="Stylesheet" type="text/css" /> <link href="Stylesheets/StyleSheet2.css" rel="Stylesheet" type="text/css" /> What am I missing here? The regexes are essentially identical except for the text to match to? Also, I know that regex is not a great tool for HTML parsing...I will probably end up using the HtmlAgilityPack in the end, but this is driving me nuts and I want an answer if only for my own mental health!

  • Good way to extract strings to resource

    - by Bart Friederichs
    I am using Visual Studio 2010 and we just decided to get started on localization of our code. We want to use the per-form resource file in combination with a separate resource file for static strings, called strings.resx. I was wondering if there is a good way to extra static strings (we already have quite some code we need to translate) to the strings.resx file? I have tried this plugin: Resource Refactoring 2010, but it doesn't work completely. It creates the correct new resource, but the strings aren't refactored in the code. Also, the tool seems to be abandoned by its developer. Is there a good plugin that can do this?
