flash - How can the actionscript version of a swf file be determined in C#? -


What libraries or methods would be required to achieve this?

Read the first 4 bytes of the SWF file. The first 3 bytes are signatures that read (CWS or FWS) and the next byte is SWF file version. So you do not need any libraries, just come ordinary file will be enough. For the ActionScript version you need to look at the FileEventWhat tag. So it's a fake code to do this (SWF file data is in Little Aidian, so read your writeIntend or read accordingly accordingly). 

  Signature = 3 UTF bytes read as string; Version = Read a byte; Size = read unsigned int; (Int 32 bit) if (sign == "CWS") means that the SWF is compressed then unpress the rest of the bytes; // swf uses zlib compression, the first 7 bytes are compressed by rect_byte = read signed signed bytes; Rect_bits = rect_byte >> 3; // First 5 bits say that how many bits are needed for a dimensoin of swf; total_bit = rect_bits * 4; Rect_bytes = Math CEL ((total_bits - 3) / 8); // Until here we read the rect_bytes number of information bytes about the SFF dimension; Read unsigned less as frame rate; Reading unsigned less as frame count; While true {read less unsigned less in swf_tag_code_len; Tagcode = swf_tag_code_len >> 6; // First 6 bits tag code tagline = swf_tag_code_len & amp; 0x3F; // The last 10 bits set the length of the tag (if the length is less than 63) if (tag allan> = 63) {// if the tag is larger than 63 bytes, then tell the next four bytes length tagline = ungraded int reading; } If (tagcode == 69) {// We go here, we are looking for this tag (file content); read {b = unsigned byte; If (B & B (1

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...
