Command Button Not Enabling On List Box Click
Hello again everyone,Can someone help me out here. Excel 2002/vba 6. I have a form with a list box and a few command buttons. On initialization of the form I disable the "Make Table" button because I don't want the users clicking it until they have selected items from the list box. They are supposed to select items in the list box then press the button.In the listbox click event, I have this code Code:Private Sub lstbTestMeth_Click()cmdMakeTable.Enabled = TrueEnd Sub however, when you click in the listbox, the button is not enabled for some reason. Any clues why this is not working? All info I have looked up indicate that setting enabled to true should bring the button back. The button is not locked either. Maybe I've got the code in the wrong event? Thanks, Hilfy

Converting A Custom Command Button To A Standard VB Command Button
Hey there,The task at hand is as follows: I have a large VB project with many forms that use a custom command button (it is the Gurhan Button, a freeware control available from PSC and other places). What I want to do is replace the Gurhan button en masse to the standard VB button.What I have done is written a simple VB program that reads in the .frm files of the project as text, and made the appropriate replacements. This works fine except for the Picture property. In other words, a line like this:Picture = "Form1.frx":11B4causes problems in the converted project. When I open the new form, I get the "There were errors, check log file for details" message. The log file message, not very useful, contains lines like this:Line 12: Property Picture in GurhanButton1 could not be set.Now, I am not an expert on frx files, but I would think that the reference to "Form1.frx":11B4 in the Picture property refers to its location in the file? And if so, the frx file is not being changed, so I am at a loss as to why VB cannot set the property. Any ideas?

Get An Unspecified Amount Of Inputs To Sort?
I am working on php script that takes an input (using html) stores those values in a separate text file. I managed to get that to work. But the thing is I wanted to be able to sort those values alphabetically. Since their are an unspecified amount of inputs I tried using an explode on my output in order to store those values as an array so that I can sort them. Problem is explode makes each input its own separate array instead of one whole array. I figure some type of loop is needed to fix that but I can't figure out how to go about creating it. $filename = "ip_collection.txt"; $fileHandle = fopen('ip_collection.txt', 'a+') OR die("can't open file "); $ip = $_SERVER['REMOTE_ADDR']; $name = stripslashes($_POST['lastName'] . ", " . $_POST['firstName']); $textFromForm = $name. " | " . $ip; $newtext = $textFromFile . $textFromForm; [Code]....

Could anyone give me some tips to help me get started or point me towards a tutorial or something?

Jquery :: Disable Certain Keys If Text Input Field Exceeds X Number Of Characters?
$('.licensetable :text').live('keydown', function (event) { if ((event.keyCode < 48 || event.keyCode > 57) && (event.keyCode < 96 || event.keyCode > 105) && (event.keyCode != 8)) { event.preventDefault();[code].... I only allow numbers. This works. But if i log $(this).val().length Its obviously "one step after".If i bind the keyup event, i get the correct number. But then i cant disable the keypress event.

Jquery :: Insert Default Value If Input-text Is Deleted
I have the following piece of jQuery code: [code]If a user have posted the form, and something is entered into one of the fields, then I can't show the default value in the field, if the user deletes the text from the input field.This is happening because the value of the text-field is still containing something, even when the user deletes the content. So my problem is how to show the default value when the form is submitted, and the user then removes the typed in content?When the form is submitted the input looks like this, and keeps looking like this until the form is submitted again:<input type="text" value="someValue" defaultvalue="From" />So I need to show the default value in the input-field right after the user have deleted the content in the field, and removed the focus from the field.

Jquery :: Forms - Renew A Text Input Value In A Js Var
I have a jquery + plugin Boxy + form input mess. Thats the situation: 1 - when I press a link, a form with only a text input and a submit button appears in a popup. 2- When I write some text and press the submit button, I get the text input value in a js var, and send it by ajax to a PHP function that performs a operation a returns the result. 3 - I get the result, and the popup is closed. All is fine. My problem begins when I want to repeat the operation. When I click the link in the step 1 to make the form to appear, the text input in the form still has the first operation value. I thought it should be a new form, but it seems to be still the first one. I don´t know how to renew the text input value. Here´s my code: (still in develop phase) <script type="text/javascript"> $(document).ready(function() { var myForm = '<div><form action="" method="">'; myForm += 'New gallery name <input type="text" name="galleryName" /><br />'; myForm += '<input type="button" name="create" value="create" />'; myForm += '</form></div>'; [Code]...

I have to input fields: "label" and "url".When you write something into the label field it should be duplicated into the url field.This works like a charm, but I need the url field to be (url_encoded or sanitized) rather it would like to replace special characters with customized ones e.g. 'ä' with 'ae' or ' ' with '+'.I figured I could just use a RegEx function to replace things like ä or é but I do not get it right.

Logic For Building A Query From Inputs?
I have 4 input fields and its driving me crazy because i can't figure out when to dynamically add the AND condition right now my raw query looks like this: SELECT * FROM `staff` " . $where . $location .

JQuery :: Use One Input Text Field To Drive Two Hidden Input Text Fields?
I have a problem created by my complete [rookie] status – only second time venturing into jQuery. I created a simple shopping cart using php and the PayPal buttons (1: buy now, 2: add to cart). The php back end does it great, it generates the table and the buttons and everything works just like it’s supposed to; Except, I forgot to add sizes. So I found out what I need to add, and I realize that the way the buttons work, I will have two different text boxes for size. Not very visually appealing, and since I’m not submitting this to the server before it goes to PayPal to pay, I cannot modify it with php the way I normally would. jQuery / javascript are my only hope of making this work. What I want to do:Have a single textbox where [size] is entered by the user. Copy the value from the [correct] text box to the Value=�� section of the now hidden field in the PayPal form That way, no matter whether they [BUY NOW] or [ADD to CART] the right size is submitted to the PayPal shopping cart. This is the actual PayPal code that I’m trying to change <table> <tr> <td> <input type="hidden" name="on1" value="Size" maxlength="200">Size</td> [code]..... I got this far, and then decided to find how to insert the "enteredVALUE" into the right place in the input text field (what I called output) and I've not been able to figure out how to stuff it in there.

Jquery :: Text Input Fields That Display Instruction (placeholder) Text
What's the best way to have a text input field that displays instructions of what to enter in that field in gray. When you focus on that input field, the gray instruction text disappears and your input text appears black. If you erase your input text and focus away from that input, then the instruction gray text reappears. I've tried implementing this with jQuery, but I get all kinds of weird issues with different browsers. Sometimes when you go back a screen, the instruction text becomes black and no longer disappears, issues like that. Is there a standard javascript library for this? I can't find any! the instruction text can't be an image because it has to be available in different languages depending on the browser's language preference.
