c# - How to check if two System.Drawing.Color structures represent the same color in 16 bit color depth? -


How can I check that the two systems Drawing The color structure represents the same color in depth of 16-bit color (or usually the screen's value, the primary screen. BeatsPixel)?

Suppose I set the form. Transparency Voice1 (color type), I want to know that when the user chooses a new background color for the form (value 2), I do not set completely transparent.

On the 32-bit color depth screen I compare two values:

If (value1 == value2)

However, this 16bit color Depth does not work on the screen, because the more color values ​​for value 2 will represent the same real 16bit color as value 1, because I found the hard way.

Try the following code: 

  zero myTestMethod () {TransparencyKey = Color.FromArgb (128, 128, 64); BackColor = Color.FromArgb (128, 128, 71); Byte TR = Convert R (Transparency R); Byte TG = Convertji (Transparency.G); Byte TB = Convertib (Transparency.b); Byte BR = Convert R (Backcorer.); Byte BG = Convertiji (backcolor.g); Byte Bb = convert B (backcolor.b); If (TR == BR & TG == BG & TB == BB) {message box. Show ("par:" + + +, "+ + + + +", "+ + + TB + \" \ N "+ BR +", "+ BG +", "+ BB");} Else {MessageBox.Show ("Not equal:" + + TR + "," + TG + "," + TB + "\ r \ n" + BR + "," + BG + "," + BB) "}} Byte ConvertR (Byte Colorbet) {Return (Byte) (((Double) Colorbit / 256.0) * 32.0) Byte ConvertG (Byte Colorabette) {Return (Byte) (((Double (Double) Colorbet / 256.0) * 64.0);} Byte Convertby (Byte Colorabette) {Return (Byte) (((Double () Colorbet / 256.0) * 32.0);}

Stupid with TransparancyKey and BackColor to see if it's your L A works. Did it for me and yes, I know that it is bloated and ugly code, it is just an example of course.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
