  • Need Help with Page Life Cycle(I think it is screwing me up)

    - by chobo2
    Hi I have dragged a empty asp.net table onto my webform. I generate all the rows in the code behind those. Now my table gets filled up and has dropdown lists. When the user hits save I go through all the rows and update the values from the dropdownlist in the db. This works all great. However if 2 columns have each have "Present" then those 2 columns should be not be shown anymore and 2 new columns get put in its place with other dropdown lists. This all works. However you have to refresh the entire page to for the 2 columns that should go away to go away. So what I tried to do is at the end of the button click event. Clear the whole table and then regenerate it. However when I do this then my values are not saved to the database anymore for whatever reason. if (IsPostBack == false) { // check if dummy variables exist in db- If true just generate tables with values in db. If not generate them. } else { // grab the values from the database // generate tables with the values } btn click event { go through all rows in table(foreach loop) update each column in the database with cells in each row. while in foreach loop. //done } So this is how it goes and it works expect(all correct values are saved) the table is just not updated to the user. Does not work if (IsPostBack == false) { // same code as above } // if postback is true do nothing. By the time it gets to the click event it says there is zero rows in the table so nothing happens. btn click event { // same code } Fails also. if (IsPostBack == false) { // same code as above } else { // same code as above but moved into its own method. gernerateTable(); } btn click event { // update all rows // once done clear the Tables rows // call generateTable() } This last one does nothing as for some reason it does not update anything. I don't understand why. So what am I doing wrong with this life cycle something in my process is wrong. The code works just not when I want the table to be updated right away.

  • Get total size of all Shared Folders (Except Admin Shares) from a list of Servers?

    - by bEUY
    Hi there, I'm looking to calculate the total size of all shared folders (except admin shares) on a number of different servers (consolidating all accessed files to a NAS box for easier backup / restore) but am having a bit of trouble finding a solution. I'm certain this could be done in powershell but I just can't find the right information to get me going, I can currently spit out a list of all shares on the servers but am not sure where to go from here: $servers =@( "server1", "server2") foreach($server in $servers) { get-WmiObject Win32_Share -computerName $server -filter "Type = 0" }

  • List in velocity macro, cannot find

    - by fastcodejava
    I put a list strings as validTypes in velocity. When I do : #if (${validTypes}.contains("aaa")) // do something #end it throws an error. But when I do : #foreach (${validType} in ${validTypes}) ${validType} #end it works fine. Do I need to use velocity tools for this? How do I use it in an eclipse plugin? Are there any work around without using velocity tools?

  • Go through a number of functions in Python

    - by Asaf
    I have an unknown number of functions in my python script (well, it is known, but not constant) that start with site_... I was wondering if there's a way to go through all of these functions in some main function that calls for them. something like: foreach function_that_has_site_ as coolfunc if coolfunc(blabla,yada) == true: return coolfunc(blabla,yada) so it would go through them all until it gets something that's true. thanks!

  • php zencart mod - having problems with attributes array

    - by user80151
    I inherited a zencart mod and can't figure out what's wrong. The customer selects a product and an attribute (model#). This is then sent to another form that they complete. When they submit the form, the product and the attribute should be included in the email sent. At this time, only the product is coming through. The attribute just says "array." The interesting part is, when I delete the line that prints the attribute, the products_options_names will print out. So I know that both the product and the products_options_names are working. The attribute is the only thing that is not working right. Here's what I believe to be the significant code. This is the page that has the form, so the attribute should already be passed to the form. //Begin Adding of New features //$productsimage = $product['productsImage']; $productsname = $product['productsName']; $attributes = $product['attributes']; $products_options_name = $value['products_options_name']; $arr_product_list[] = "<strong>Product Name:</strong> $productsname <br />"; $arr_product_list[] .= "<strong>Attributes:</strong> $attributes <br />"; $arr_product_list[] .= "<strong>Products Options Name:</strong> $products_options_name <br />"; $arr_product_list[] .= "---------------------------------------------------------------"; //End Adding of New features } // end foreach ($productArray as $product) ?> Above this, there is another section that has attributes: <?php echo $product['attributeHiddenField']; if (isset($product['attributes']) && is_array($product['attributes'])) { echo '<div class="cartAttribsList">'; echo '<ul>'; reset($product['attributes']); foreach ($product['attributes'] as $option => $value) { ?> Can anyone help me figure out what is wrong? I'm not sure if the problem is on this page or if the attribute isn't being passed to this page. TIA

  • Can I use "map" as a substitute for "for each"/"for in"?

    - by John Mee
    For a little while now javascript has the "map" function to loop over arrays. It appears possible to use it as a 'foreach' operator for example: var arr = ['a','b','c'] var doubles = arr.map(function(val){ return val + val }) Is this better or worse than saying for(var i in arr){ ... 50/50: saves having to use the index but adds a callback; it doesn't seem very common so I hesitate to use it but still want to.

  • LINQ: How to skip one then take the rest of a sequence

    - by Marcel
    Hi All, i would like to iterate over the items of a List<T>, except the first, preserving the order. Is there an elegant way to do it with LINQ using a statement like: foreach (var item in list.Skip(1).TakeTheRest()) {.... I played around with TakeWhile , but was not successful. Probably there is also another, simple way of doing it?

  • How do I perform this XPath query with Linq?

    - by John Hansen
    In the following code I am using XPath to find all of the matching nodes using XPath, and appending the values to a StringBuilder. StringBuilder sb = new StringBuilder(); foreach (XmlNode node in this.Data.SelectNodes("ID/item[@id=200]/DAT[1]/line[position()>1]/data[1]/text()")) { sb.Append(node.Value); } return sb.ToString(); How do I do the same thing, except using Linq to XML instead? Assume that in the new version, this.Data is an XElement object.

  • Is there a way to make PHP's SplHeap recalculate? (aka: add up-heap to SplHeap?)

    - by md2k7
    I am using an SplHeap to hold graph nodes of a tree with directed edges that will be traversed from the leaves to the root. For this, I precalculate the "fan-in" of nodes and put them into the heap so that I can always retrieve the node with the smallest fan-in (0) from it. After visiting a node, I reduce the fan-in of its successor by 1. Then obviously, the heap needs to be recalculated because the successor is now in the wrong place there. I have tried recoverFromCorruption(), but it doesn't do anything and keeps the heap in the wrong order (node with larger fanIn stays in front of smaller fanIn). As a workaround, I'm now creating a new heap after each visit, amounting to a full O(N*log(N)) sort each time. It should be possible, however, to make up-heap operations on the changed heap entry until it's in the right position in O(log(N)). The API for SplHeap doesn't mention an up-heap (or deletion of an arbitrary element - it could then be re-added). Can I somehow derive a class from SplHeap to do this or do I have to create a pure PHP heap from scratch? EDIT: Code example: class VoteGraph { private $nodes = array(); private function calculateFanIn() { /* ... */ } // ... private function calculateWeights() { $this->calculateFanIn(); $fnodes = new GraphNodeHeap(); // heap by fan-in ascending (leaves are first) foreach($this->nodes as $n) { // omitted: filter loops $fnodes->insert($n); } // traversal from leaves to root while($fnodes->valid()) { $node = $fnodes->extract(); // fetch a leaf from the heap $successor = $this->nodes[$node->successor]; // omitted: actual job of traversal $successor->fanIn--; // will need to fix heap (sift up successor) because of this //$fnodes->recoverFromCorruption(); // doesn't work for what I want // workaround: rebuild $fnodes from scratch $fixedHeap = new GraphNodeHeap(); foreach($fnodes as $e) $fixedHeap->insert($e); $fnodes = $fixedHeap; } } } class GraphNodeHeap extends SplHeap { public function compare($a, $b) { if($a->fanIn === $b->fanIn) return 0; else return $a->fanIn < $b->fanIn ? 1 : -1; } }

  • symmetrical text scramble

    What is the EASIEST way to do this. XOR 0x80 may be too obvious but that COULD work. Whats the easiest way to take a windows filename (/ \ and other chars are illegal) and scrambling them so no one knows the original filename? I would like to undo this as well. I am seriously thinking foreach on the filename and just XORing them
