c# - Get file to send as attachment from byte array -

-

I have an ASP.NET MVC application that has a list of recipients given a specific "project" I get this information from a report using SQL Server Reporting Services (SSRS).

I have not used SSR before, but I got some code from a colleague where they used it. What he does with the report he downloads it to the client's machine in the browser, so if I do not do this, then I sit with a byte array with report data.

Is there a way that I can send files as an attachment on file system without first writing them physically? The report will dry out in Excel format or PDF.

Edit: I am using SmtpClient to send an email.

To do this, you will need to take advantage of this type of SSRS ReportManager API.

  1. Read the report from the web service with the SSRs first
  2. Instead of saving the server or the client, read the file in memory
  3. MemoryStream object directly e Send -mail to server 

      string strReportUser = "RSUserName"; String strReportUserPW = "MySecretPassword"; String strReportUserDomain = "DomainName"; String sTargetURL = "http: // SqlServer / ReportServer?" + "/ MyReportFolder / Report1 & amp; rs: command = render & amp; amp; amp; rs: format = PDF & ReportParam =" + ParamValue; HttpWebRequest req = (HttpWebRequest) WebRequest.Create (sTargetURL); req.PreAuthenticate = true; Req.Credentials = New System.Net.NetworkCredential (strReportUser, strReportUserPW, strReportUserDomain); HttpWebResponse HttpWResp = (HttpWebResponse) req.GetResponse (); Stream fstream = httpWResp.GetResponseStream (); HttpWResp.Close (); // Now fold around and send it as feedback .. ReadFullyAndSend (fStream);   
     ReadFully and send the method NB: SendAsync calls so that you are not waiting to send the email completely before sending the email to the server completely.  
      public static blank ReadFullyAndSend (stream input) {(MemoryStream MS = New MemoryStream ()) using {input.CopyTo (ms); Mail message message = new mailmessage ("from@foo.com", "too@foo.com"); Attachment attachment = new attachment (MS, "my attachment", "application / vnd.ms-excel"); Message.Attachments.Add (attachment); Message.Body = "This is an async test."; SmtpClient smtp = New SmtpClient ("localhost"); Smtp.Credentials = New network credentials ("EFU", "bar"); Smtp.SendAsync (message, empty); }}

python - Writing Greek in matplotlib labels, titles -

Image
I'm trying to write some text for labels, shape titles etc. with my plots, but no benefit till now Has not happened . I do not want to print specific characters (I know how to use special characters), I want to write the entire text in Greek (maybe Unicode and text ' ?). , suggesting that I would like to mention that for some reason I can not get matplotlib to cooperate with Tex (using IPython notebook from Anaconda in Ubuntu 14.10) so that there really is an option Will not be the first. I tried loading the Arial font and it loads successfully but again I get square blocks instead of characters. I import matplotlib.font_manager FM PROP = FM Font Properties (fname = '/ usr / share / fonts / truetype / msttcorefonts / Arial.ttf') And then to display the string I u'Î? ? I ?? Î¿Ï ??

c# - LINQ to Entities does not recognize the method 'Int32 IndexOf(System.String, System.StringComparison)' method -

I have performed a linq query using Entityframework as below GroupMaster getGroup = Null; GetGroup = DataContext.Groups.FirstOrDefault (item = & gt; keyword.IndexOf (item.Keywords, StringComparison.OrdinalIgnoreCase)> = 0 & amp; amp; item.ISNAmd) I found an exception like the method when executing it LINQ units do not recognize the 'Inter 32 index of (system string, system. String compromise)' method, and This method can not be translated to Store expression. Includes () method is sensitive by default, then I need to convert to minimize. Is there any method in which a string match match is examined and whether there is any method to solve the index question of the method? You actually have four options Databases globally Change the colon of it can be done in many ways, a simple Google search should reveal to them. Change the mix of individual tables or columns. Use a stored procedure and specify the call statement on your query Perform...

Pygame memory leak with transform.flip -

-
Today I came across an interesting issue which, by writing a small side scroller, instead of a sprite sheet, I was planning to use because I lacked a good "packer" for making phantom sheets (and honestly with patience and passion as it is only a test project). Anyway, I showed the animation running on the right of 8 PNG (with transparency). I considered it a good idea to prepare the flipped images to run on the left in the consultant, and the frame is not framed when the game is running (Flip actually consumes a lot of CPU like I Was measured). > To get access to the loop, I get the memory leak self.move_l = [# 8 PNG images with transparency to the right] For the self in IMG. Move_l: self.move_r.append (pygame.transform.flip (img, true, false) error traceback: traceback (most recent Call final): The file "D: \ Python 34 \ _Projects \ efg \ efg.py", in line 196, in the & lt; module & gt; main = master program ((1024, 680)) "D: \ Python ...
