• Error debugging - Conversion from String to Double

  - by Jamie Taylor

  I'm doing some error debugging trying to get the errors on our website down to a minimum and there seems to be an error that is popping up quite a lot Conversion from string "" to type 'Double' is not valid. I'm unable to replicate this problem but I can see that it is happening. I've been looking through the code in one of the pages and strolled across this Dim varWeek As String If varWeek < 10 Then 'Do something' End If Could this be causing the problem as it is trying to see if a String is less than 10 which is an Integer? As I said before as I am unable to see this error in the first place so changing this to an Integer doesn't change anything on my system. Thanks.

• C++ -malign-double compiler flag

  - by Martin

  I need some help on compiler flags in c++. I'm using a library that is a port to linux from windows, that has to be compiled with the -malign-double flag, "for Win32 compatibility". It's my understanding that this mean I absolutely have to compile my own code with this flag as well? How about other .so shared libraries, do they have be recompiled with this flag as well? If so, is there any way around this? I'm a linux newbie (and c++), so even though I tried to recompile all the libraries I'm using for my project, it was just too complicated to recursively find the source for all the libraries and the libraries they're dependent on, and recompile everything.

• IIS Active Directory double handshake hickup

  - by AngryHacker

  I have a .net 2.0 click-once application that connects to IIS web services on Windows 2003 R2 64-bits. The IIS is setup with Integrated Windows Authentication. So whenever a web service call is made to IIS web services, there is a double handshake taking place: Client Request #1 GetEmployeeList Server Response #1 <- 401 HTTP/1.1 401 Unauthorized WWW-Authenticate: Negotiate WWW-Authenticate: NTLM Client Request #2 REQUEST Header... Server Response #2 <- 200 Data Received Lately, however, Server Response #1 will sometimes (a good 20 percent of the calls) take a massive amount of time (like 25 to 30 seconds). How do I debug this problem? Is this a Active Directory problem or a Domain Controller problem?

• Building and rendering a bitmap from a double array

  - by Ami

  I'm new to c# and I'm sure I'm missing something simple here. I'm trying to build a bitmap from integer values (0-255) in a double array and then render it in a PictureBox. I think my Bitmap is getting generated but it isn't displaying in my PictureBox. Bitmap bmp = new Bitmap(image_width, image_height); Color pxl_color = new Color(); for (int i = 0; i < image_width; i++) { for (int j = 0; j < image_height; j++) { pxl_color = Color.FromArgb(array_bitmap[i][j]); bmp.SetPixel(i, j, pxl_color); } } PictureBox1.Image = bmp; Thanks in advance.

• Drupal form being rendered before submit action

  - by alxp

  I have a Drupal module page where I am populating a form with a drop-down that contains a list of available parts of a set of files that the user can upload. Once the user uploads a file of a certain type, it removes that option from the list, and when all the available files are uploaded the form will not be rendered. The problem is that Drupal is drawing the form before it carries out the submit action, so it appears to the user that the operation didn't work until they reload the page. What is the common way to deal with this? Setting form_state['redirect'] to go to the page doesn't seem to work.

• Baffled by PHP escaping of double-quotes in HTML forms

  - by rjray

  I have a simple PHP script I use to front-end an SQLite database. It's nothing fancy or complex. But I have noticed from looking at the records in the database that anything I enter in a form-field with double-quotes comes across in the form-processing as though I'd escaped the quotes with a backslash. So when I entered a record with the title: British Light Utility Car 10HP "Tilly" what shows up in the database is: British Light Utility Car 10HP \"Tilly\" I don't know where these are coming from, and what's worse, even using the following preg_replace doesn't seem to remove them: $name = preg_replace('/\\"/', '"', $_REQUEST['kits_name']); If I dump out $name, it still bears the unwanted \ characters.

• Question about a dialog form and submit errors

  - by user248959

  Hi, I have the link below that executes the action message/new which shows a form inside a jqueryui modal dialog. <div id="myDialog"> </div> echo jq_link_to_remote('Enviar mensaje', array( 'url' => 'mensaje/new?receptor='.$miembro->getId().'&tipo=0&estado=0', 'update' => 'myDialog', 'complete' => "jQuery('#myDialog').dialog({ width:375, height:220, top:123, resizable:false, modal:true, autoOpen: false }); jQuery('#myDialog').dialog('open')" )); The point: if there are submit errors the form is not showed inside the dialog form but in a empty page (mensaje/create).. Any idea? Javi

• Escaping and unescaping a string with single and double quotes in Javascript

  - by Reina

  I have a search box that a user can search for any string including single AND double quotes, once they have searched, the backend is passing the keyword back to me so I can put it back in the box. I don't know what the string is so I can't escape quotes myself, below is an example: var keyword = "hello"; $("#selectionkeywords").val(); The issue I am having is that if the user enters "hello" the keyword becomes ""hello"" and I get this error: missing ) after argument list [Break On This Error] jQuery("#selectionkeywords").val(""hello""); The user could also enter single quotes so that rules it out as well. I tried using escape unescape but I still have the same issue e.g. escape(""hello"") I could get the value in an unescaped format e.g. "hello" but I don't know what to do with it, escape doesn't work on it I end up with this %26%23034%3Bhello%26%23034%3B So I'm pretty much stuck at the moment as I can't do anything to the string, any ideas?

• Propor usage of double and single quotes?

  - by Phox

  I'm talking about the performance increase here. From all I know you can echo variables in double quotes ("), like so: <?php echo "You are $yourAge years old"; ?> But single quotes will just return You are $yourAge years old. But what about performance differences? I've always gone by the rule that single quotes are faster because the PHP interpreter doesn't have to search through the string for variables. But I'm seeing more and more blog and forum posts on the web saying differently. Does anyone actually have any information on this subject? Perhaps benchmark tests or something? Cheers.

• Javascript: Perform function on form submit

  - by flight643

  Hopefully this is a pretty simple question! I've got the code working in jQuery to listen for a specific form on a page to be submitted and perform an alert when it is.. I.e.: The form itself doesn't have a name so I am targetting the form within a specific form ID. $("#content form").submit(function() { alert("lorem ipsum dolor?"); }); What would be the syntax for performing this in javascript alone without using jquery? For example, I have this code (below) and just am unsure of how to listen for the form to be submitted to perform an action.. var submitform = document.getElementById("content").getElementsByTagName("form"); Thanks!

• Why does AddMilliseconds round the double paramater?

  - by fearofawhackplanet

  DateTime.Now.AddMilliseconds(1.5); // adds 2 milliseconds What on earth were they thinking here? It strikes me as horrendously bad practice to create a method that takes a double if it doesn't handle fractional values. Why didn't they implement this with a call to AddTicks and handle the fraction properly? Or at least take an int, so it's transparent to callers? I'm guessing there must be a good reason why they implemented it this way, but I can't think of what it could be. Can anyone offer any insight?

• Submit form if ajax validator returns true using jquery

  - by Anthony

  I am not sure where I'm going wrong. The idea is that before the form is submitted, one of the input fields is sent to a server-side validator via ajax. If the response is 1, the input is valid and the form should be submitted. If the response is 0, the form should not be submitted. The issue is that I can't figure out how to set a variable within the ajax request function that will prevent the form from being submitted. This is what I have: $("#form").submit(function() { var valid= false; var input = $("#input").val(); $.ajax({ type: "POST", url: "validator.php", data: "input=" + input, success: function(msg){ valid = (msg == 1) ? true : false; if(!valid) { $("#valid_input").html("Please enter valid info"); } else { $("#valid_input").html(""); } } }); return valid; });
