HTML Colour Mixer / Time To Get Out Crayons

Jul 8, 2011

I have a project that needs to produced an array list of hexadecimal colour codes by taking in two colour codes and the number places in the array list. The two colours need to be mixed together and then diluted across the number in the array list.For example, If colour one was red, the second colour was green and the number passed in was 3 the array list that would be produced would be something like [code] The W3Schools has exactly what im looking for, but they have used a fix number of colours returned. I just need to be able to vary the number of colours bought back and how strong they are. url....

Html - Regular Expression From Font To Span (size And Colour) And Back (.NET)?

Mar 26, 2010

I am looking for a regular expression that can convert my font tags (only with size and colour attributes) into span tags with the relevant inline css. This will be done in VB.NET if that helps at all.I also need a regular expression to go the other way as well.To elaborate below is an example of the conversion I am looking for:

<font size="10">some text</font>

To then become:

<span style="font-size:10px;">some text</span>

So converting the tag and putting a "px" at the end of whatever the font size is (I don't need to change/convert the font size, just stick px at the end).The regular expression needs to cope with a font tag that only has a size attribute, only a color attribute, or both:

<font size="10">some text</font>
<font color="#000000">some text</font>

[code]....

I also need another regular expression to do the opposite conversion. So for example:

<span style="font-size:10px;">some text</span>

Will become:

<font size="10">some text</font>

As before converting the tag but this time removing the "px", I don't need to worry about changing the font size.Again this will also need to cope with the size styling, font styling, and a combination of both:

<span style="font-size:10px;">some text</span>
<span style="color:#000000;">some text</span>

[code]....

I am extracting basic HTML & text from CDATA tags in an XML file and then displaying them on a web-page.The text also appears in a rich-text editor so it can be edited/translated, and then saved back into a new XML file. The XML is then going to be read by a flash file, hence the need to use old-fashioned HTML.

The reason I want to convert this code is mainly for display purposes. In order to show the text sizes correctly and for it to work with my rich text editor they need to be converted to XHTML/inline CSS. The rich text editor will also generate XHTML/inline CSS that I need to convert 'back' to standard HTML before it is saved in the XML file.I know the temptation will be to tell me a number of different ways to set up my code to do what I want but there are so many other permutations I haven't even mentioned which have forced me down this route, so literally all I want to do is convert a string containing standard HTML to XHTML/inline CSS, and then the same but the other way round.

Colour Picker Scanning - Log On Method - Users Selecting A Colour From A Paint Panel

Mar 15, 2012

To .NET after getting tired of using VB6 due to the lack of functionality. I'm trying to create a log on method for a system which will involve users selecting a colour from a paint panel and then placing/drawing the colour in 1 or more tiles of a grid, basically a 3x3 grid in which for example they selected the blue colour and drew in the top left tile and the bottom left tile. The logon is selecting the correct colour and placing the colour in the appropriate tile. What i want them to be able to do is place even a single pixel of colour so it has a high accuracy. So far i have a timer which loops from the width of the grid to the height of the grid.

Private Sub Timer1_Tick(sender As System.Object, e As System.EventArgs) Handles Timer1.Tick
Dim BMP As New Drawing.Bitmap(1, 1)
Dim GFX As System.Drawing.Graphics = System.Drawing.Graphics.FromImage(BMP)
GFX.CopyFromScreen(New Drawing.Point(MousePosition.X, MousePosition.Y), _

[CODE]...

To start with i have just hard coded the colour i want it to detect. At present it produces an error. Parameter must be positive and < Width the error is on System.Drawing.Point(i,j). If i place the mouse over the colour then run the program it will say it has been found, but otherwise it wont find the colour. I believe i am not updating the location of the pixel or something to that effect.

Replace All Pixels Of A Single Colour With A Different Colour?

Sep 16, 2009

I'd like to replace all the white pixels in a bitmap image with pixels of the colour "Color.FromKnownColor(KnownColor.MenuHighlight)". Is there some method in the Image, Bitmap or Graphics classes I can use, or will I simply have to inspect each pixel in the image with GetPixel, check whether it is a white pixel, and then set it with SetPixel?Here is the code I am using now:

Private Shared Sub highlight(ByVal b As Bitmap)
Dim highlightColour As Color = Color.FromKnownColor(KnownColor.MenuHighlight)
Dim whiteARGB As Long = Color.White.ToArgb

Html Source Code Doesn't Show Html But In Firebug Inspect Element Html Is There?

Jan 10, 2012

This may sound really stupid but I have to ask cause I'm not finding this answer anywhere.I have an application where the user will need to sign up for a new user account on the website [URL]..However when I am using Firefox's plug-in Firebug to view html I am getting something totally different than when I just right click on the site and view the page source.

What I am trying to do is to get the captcha from the website and display it in a picturebox on the application so the user can view the captcha, solve the captcha and then the app post is back to the service for a response.

Here is the source that I am getting using Firefox's Firebug to inspect the element:

<td>
<input type="hidden" value="Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK" name="iden">
<img class="capimage" src="/captcha/Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK.png" alt="i wonder if these things even work">
</td>

[Code]...

Why would the two be showing me two different versions of the HTML?

And how would you be able to grab that source to view in a picturebox using webclient?

Sending An HTML Email, Where The HTML Comes From An HTML File .Net/ClickOnce Environment?

Jun 20, 2009

Usage: Users create pretty HTML news letters in another app. They post the newsletter to the web, but they also want to set the contents of the HTML news letter file as the body of an email and send it using Application In Question. The users understand to use absolute link and image references when sending an E Newsletter. Environment:

AIQ is a VB.Net app deployed via ClickOnce. It is an intranet app; one can be sure MS Office 2003 and the interop 11 dlls are on the target machines.

Restrictions: MAPI is out. It mangles the HTML. Since it is a ClickOnce deployment, we can't register dlls (I think, correct me if I am wrong). Therefore CDO and COM is out (again, I may be wrong.... I would be happy to be proven so).

Html - Removing "Design-time-lock" Attribute From Legacy Code

Apr 4, 2011

I'm converting a project from .net 1.1 to 3.5, and everywhere the following is used in the markup:

Design_Time_Lock: true

e.g.

<asp:linkbutton id="lbRun" style="Z-INDEX: 111; Design_Time_Lock: True" runat="server">Run</asp:linkbutton>

[Code]....

I've read up about the Design_Time_Lock attribute, and I can see when it will and won't be generated. However I don't really understand the point of it. And- more importantly- can all instances of it be safely removed throughout the code?

Html - VB Basic RegEx - Save Value From An Input Tag In HTML Source Code

Feb 16, 2011

I am trying save a value from an input tag in some HTML source code. The tag looks like so:

<input name="user_status" value="3" />

I have the page source in a variable (pageSourceCode), and need to work out some regex to get the value (3 in this example). I have this so far: [Code] Which works fine most of the time, however this code is used to process source code from multiple sites (that use the same platform), and sometimes there are other attributes included in the input tag, or they are in a different order, eg:

<input class="someclass" type="hidden" value="3" name="user_status" />

I just dont understand regex enough to cope with these situations.

Xml - Stop Automatic HTML Encoding When Assigning To HTML Input Fields?

May 6, 2009

I have to submit a HTML form to a 3rd party website and one of the hidden fields is an XML string. The XML needs escaping before it is sent to the 3rd party.

However when I add the plain XML to the form field it semi-escapes it for me. So then when I use HTMLEncode myself part of the XML is double-escaped. How do I prevent the automatic escaping that appears to becoming from .NET.

Or even better how else can send the escaped XML via the hidden field.

XML

<systemCode>APP</systemCode>

Basic assigning to hidden input field

&lt;systemCode>APP&lt;/systemCode>

When I HTML Encode it as well

&amp;lt;systemCode&amp;gt;APP&amp;lt;/systemCode&amp;gt;

I can see what's happening - but I don't know how to prevent it?

C# - Convert A Date And Time To UTC Time Based On The Time Zone Of The User?

Sep 6, 2009

I have an ASP.NET application with a SQL Server back end. I am storing all my dates in UTC format and doing the appropriate conversions to the local time zone of the browser viewing it. One of the pages asks for a start date and end date (no times).

I am taking the start date and setting the time to 00:00:00 hours (midnight) and I'm taking the End time and adding a time of 23:59:59, so that the date range covers the whole day. Now what I'm trying to do is do a SQL query to do a search for records in this date range. The problem is, the data in SQL is in UTC time and the user is typing their dates and times in their local date and times. My quickest solution was to convert the date and time to UTC, then search the records. However, by doing this, I am to believe ASP.NET converts the given time and date to UTC based on the server time zone. How can I convert a date and time to UTC time based on the time zone of the user?
