c# - How can I load a generated Bitmap into a PictureBox? -


There are many pictures that seem to be out of the question, but I have not found any deal with changing the contents of a film The bitmap was not loaded from the file just for that.

My application takes an array of bytes and generates a bitmap from them, I really do not want to leave the file as an intermediate processing step.

Because it is an array of bytes, and is not a 2-byte word, I need to create an indexed bitmap with a grayscale palette. / P>

I then converted the indexed bitmap to normal (24 bit RGB).

This is the code that is causing me an error: 

  PhotoBoxA 1 Image = (system. Drawing image) BMP 2;

When I look at the form (tries to draw a picture), the thread will stop execution with a message: "Invalid parameter on the system, drawing.image.get_ref format ( ) "

What am I doing wrong? How do I create a safe bitmap for a picture box?

This is what makes "BMP 2": 

  // is making a bitmap from the array system. Drawing Bitmap BMP 1 = new system Drawing Bitmap (100, 100, 100, System Drawing Imaging Pixel Format.format 8 BPP Indexed, MyInTTP); // is making a proper indexed palette system. Drawing Imaging Colorepetrate grapelet = BMP1. Palette; For (int i = 0; i & lt; grapelate.in.in langati; i ++) {GrayPalet. Entries [I] = Color FARBB (I, I, I); } Bmp1.Palette = Grapelet; // Creating 24 BPRGB Bitmap for a non-indexed, PictBoob compatibility system. Drawing. Bitmap BMP2 = new bitmap (BMP1 width, BMP 1.high, system, drawing.imaging.pixelformat.form24bpRGB); Graphics GR = Graphics.Fremight (BMP2); Gr.DrawImage (bmp1, 0, 0); Gr.Dispose ();

If I use BMP 1 then Save (@ "testfile.bmp") I get a completely acceptable bitmap that appears to be without any discrepancy.

Why can not I use my bitmap as my picture.Picture? Do I need to make changes before loading the new bitmap in the extra parameters of the picture box?

Well, I got the problem from what I was doing.

I will try to explain what was wrong, but as a non-guru I am not sure how accurate I am.

Apparently setting the image in a photo box does not copy memory anywhere in my application (some tasks that I have shown away from the code snippet), by settling the "bmp1" variable having had.

I did not know that the memory associated with BMP 1 was the same memory everywhere the function passes it, and it destroys the invalid parameters on "system.Drawing.Image.get_RawFormat ()". was raised. I think it does this because every time the painting box is rediscovered, it uses its "image" property, well it attracts, because I'm settling the memory associated with the "image" property So I was working properly in the Photobookant event.

I just hope that I never have memory leaks. Setting up any bitmaps I have been dealing with.

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...
