  • GAE Having Tasks generate pages for user

    - by mellort
    I have a web app that I would like to have the following functionality: user gives a url webapp gets json data from that url and others from same website (this can take anywhere from 1-10 seconds) webapp uses data to generate page for user With this approach, I believe that if the server is in the process of getting the data for one user, then the other user won't be able to load the page (server busy). I would like to avoid this if possible. It seems like the Google Tasks API would be useful for this, but I don't see how I can run the task, and then use the output of the task to generate the page (how would the main app know when the task was finished?) What is the best way to resolve this? Thanks in advance

  • Doctrine generate models - problem with relation type

    - by mrok
    I am trying generate doctrine models from yaml schema I have schema like that: Product: columns: id: type: integer(5) primary: true unsigned: true autoincrement: true activation_time: type: datetime notnull: true enduser_id: type: integer(5) unsigned: true notnull: true relations: Enduser: foreignType: one type: one foreignAlias: Product Hostid: columns: id: type: integer(5) primary: true unsigned: true autoincrement: true value: type: string(32) fixed: true notnull: true Order: columns: id: type: integer(5) primary: true autoincrement: true unsigned: true expire_date: type: datetime description: type: clob Enduser: columns: id: type: integer(5) primary: true unsigned: true autoincrement: true hostid_id: type: integer(5) unsigned: true notnull: true order_id: type: integer(5) unsigned: true notnull: true relations: Order: foreignAlias: Endusers Hostid: foreignAlias: Endusers and the problem is that models generated by doctrine generate-models-yaml are wrong in BaseEnduser $Product is defined as Doctrine_Collection $this-hasMany('Product', array( 'local' = 'id', 'foreign' = 'enduser_id')); instead just Product object what did I wrong? relation is defined as foreignType: one type: one

  • How Can I Generate Random Unqiue Numbers in C#

    - by peace
    public int GenPurchaseOrderNum() { Random random = new Random(); _uniqueNum = random.Next(13287, 21439); return UniqueNum; } I removed unique constraint from the PONumber column in the db because an employee should only generate P.O. # when the deal is set. Otherwise, P.O. # would have 0. P.O. Number used to have unique constraint, this forces employee to generate P.O. in all cases so the db doesn't throw unique constraint error. Since i removed the unique constraint, any quote doesn't have P.O. will carry 0 value. Otherwise, a unique value is generated for P.O. #. However, i don't have a unique constraint in db which makes it hard for me to know whether the application generated P.O. # is unique or not. What should i do? I hope my question is clear enough

  • Efficiently generate a 16-character, alphanumeric string

    - by ensnare
    I'm looking for a very quick way to generate an alphanumeric unique id for a primary key in a table. Would something like this work? def genKey(): hash = hashlib.md5(RANDOM_NUMBER).digest().encode("base64") alnum_hash = re.sub(r'[^a-zA-Z0-9]', "", hash) return alnum_hash[:16] What would be a good way to generate random numbers? If I base it on microtime, I have to account for the possibility of several calls of genKey() at the same time from different instances. Or is there a better way to do all this? Thanks.

  • Generate Javadoc for interfaces only using Ant script?

    - by ipkiss
    Hi all, I am using Apache Ant to generate Javadoc for my program which has many projects(or modules). However, I just want to generate Javadoc for Interfaces ONLY and I do not know how to check if a file is a class or interface in Ant. Someone suggested me that I should use and specify a list of files to exclude or include. However, there are hundreds of files in my program and specifying a list of class files to exclude is impossible. Does anyone have some ideas, please?

  • Templating Engine to Generate Simple Reports in .NET

    - by dr. evil
    I'm looking for a free templating engine to generate simple reports. I want some basic features such as : Ability to Write Loops (with any IEnumerable) Passing Variables Passing Templates Files (main template, footer, header) I'll use this to generate reports in HTML and XML. I'm not looking for a ASP.NET Template Engine. This is for a WinForms applications. I've seen this question http://stackoverflow.com/questions/340095/can-you-recommend-a-net-template-engine, however all of those template engines are total overkill for me and focused for ASP.NET. Please only recommend free libraries. // I'm still looking an NVelocity but it doesn't look any promising for .NET, overly complicated, when you download it's bunch of files not clear what to do, no tutorial, startup document etc.

    - by DoDo
    Hi! does anyone have working example of CryptGenrRandom class to generate session id (need to use in my iis module). HCRYPTPROV hCryptProv; BYTE pbData[16]; if(CryptAcquireContext( &hCryptProv, NULL, NULL, PROV_RSA_FULL, CRYPT_VERIFYCONTEXT)) { if(CryptGenRandom(hCryptProv, 8, pbData)) { std::string s(( const char *) pbData); printf(s.c_str()); } else { MyHandleError("Error during CryptGenRandom."); } } else { MyHandleError("Error during CryptAcquireContext!\n"); } i tried this code but, its not working quite well (i get it from msdn) and this example don't work for me ( http://www.codeproject.com/KB/security/plaintextsessionkey.aspx ) so if anyone know how to generate sessionid using this class plz let me know tnx anyway!

  • Generate combinations by order and fixed length.

    - by roconmachine
    Suppose there is array main[] = [a,b,c,....z]; a[] = [a1,a2,a3,....] , b[] = [b1,b2,b3,....] and so on. So if we generate combination in main.length of ordered then it looks like ..... a1 b1 c1, a1 b1 c2, a1 b1 c3 ...... a1 b2 c1, a1 b3 c1, ..... a2 b1 c1, a3 b1 c1, ..... and total count will be a.length * b.length * c.length ........ = ? So write a code in any language to generate those combination. all the best. alex

  • how to generate large image in compact framework

    - by Buthrakaur
    I need to generate large images (A4 image at 200 DPI, PNG format would be fine) in my compact framework application. This is impossible to do in standard way due to memory limitations (such big image will throw OOMException). Is there any library which offers file-backed stream image generation? Or I could generate many smaller stripes of images (each stripe representing a row of the large image) using standard Bitmap approach, but I need to merge them together afterwards - is there any method how to merge many smaller images into one large without having to instantiate large Bitmap instance (which would again cause OOM)?

  • Fastest Way to generate 1,000,000+ random numbers in python

    - by Sandro
    I am currently writing an app in python that needs to generate large amount of random numbers, FAST. Currently I have a scheme going that uses numpy to generate all of the numbers in a giant batch (about ~500,000 at a time). While this seems to be faster than python's implementation. I still need it to go faster. Any ideas? I'm open to writing it in C and embedding it in the program or doing w/e it takes. Constraints on the random numbers: A Set of numbers 7 numbers that can all have different bounds: eg: [0-X1, 0-X2, 0-X3, 0-X4, 0-X5, 0-X6, 0-X7] Currently I am generating a list of 7 numbers with random values from [0-1) then multiplying by [X1..X7] A Set of 13 numbers that all add up to 1 Currently just generating 13 numbers then dividing by their sum Any ideas? Would pre calculating these numbers and storing them in a file make this faster? Thanks!

  • What is the best way to add attributes to auto-generated entities (using VS2010 and EF4)

    - by Dani
    ASP.NET MVC2 has strong support for using attributes on entities (validation, and extending Html helper class and more). If I generated my Model from the Database using VS2010 EF4 Entity Data Model (edmx and it's cs class), And I want to add attributes on some of the entities. what would be the best practice ? how should I cope with updating the model (adding more fields / tables to the database and merging them into the edmx) - will it keep my attributes or generate a new cs file erasing everything ? (Manual changes to this file may cause unexpected behavior in your application.) (Manual changes to this file will be overwritten if the code is regenerated.)

  • Generate "Finder.h" for a SIMBL plugin

    - by user1204395
    I'm trying to create a SIMBL plugin for Finder to add icon overlay over some files. I have this code: @implementation NSObject (FAIconOverlay) - (void)FAIconOverlay_TIconAndTextCell_drawIconWithFrame:(struct CGRect)arg1 { [self FAIconOverlay_TIconAndTextCell_drawIconWithFrame:arg1]; if (![self respondsToSelector:@selector(node)]) { return; } NSLog(@"%@", [[[NSClassFromString(@"FINode") nodeWithFENode:[(TNodeIconAndNameCell *)self node]] fullPath] lastPathComponent]); // Draw the icon overlay } - (void)FAIconOverlay_TDesktopIcon_drawIconInContext:(struct CGContext *)arg1 { [self FAIconOverlay_TDesktopIcon_drawIconInContext:arg1]; } @end I can draw the icon overlay but, when I try to get the path of the file I get a "Use of undeclared identifier TNodeIconAndNameCell". Looking this link < How to Write OS X Finder plugin I see that is neccessary to generate a Finder.h file... My question is: How to generate this file?? I tried running "class-dump -H Finder.app" but I get too more compiling errors Thank you very much!

  • Generate (in R) a matrix of all possible outcomes for throwing n dice (ignoring order)

    - by Brani
    In cases where order does matter, it's rather easy to generate the matrix of all possible outcomes. One way for doing this is using expand.grid as shown here. What if it doesn't? If I'm right, the number of possible combinations is (S+N-1)!/S!(N-1)!, where S is the number of dice, each with N sides numbered 1 through N. (It is different from the well known combinations formula because it is possible for the same number to appear on more than one dice). For example, when throwing four six-sided dice, N=6 and S=4, so the number of possible combinations is (4+6-1)!/4!(6-1)! = 9!/4!x5! = 126. How can I generate a matrix of these 126 possible outcomes? Thank you.

  • Entity Framework 4.1 auto generate with DbContext when creating ADO.NET Entity Data Model

    - by smudgedlens
    I would like to work with DbContext instead of ObjectContext. I updated EF so now I have the DbContext, but I want to generate my strongly-typed context based on the DbContext and not the ObjectContext. When I add new ADO.NET Entity Data Model, it is still based on the ObjectContext. Is it not possible to have it base off of DbContext in Visual Studio 2010 with EF 4.1? UPDATE: Okay, I followed the directions in this link and was able to generate the DbContext template objects. However, now it is saying there is ambiguity between the template entities and the entities in my .edmx file. How do I resovle this? Do I blow away the ones in the .edmx file?

  • Generate a polygon from line.

    - by VOX
    I want to draw a line with thickness in j2me. This can easily be achieved in desktop java by setting Pen width as thickness value. However in j2me, Pen class does not support width. My idea is to generate a polygon from the line I have, that resembles the line with thickness i want to draw. In picture, on the left is what I have, a line with points. On the right is what I want, a polygon that when filled, a line with thickness. Could anyone know how to generate a polygon from line? http://www.freeimagehosting.net/uploads/140e43c2d2.gif

  • Tool that auto-generate a code for accesing a xml-file

    - by alex
    My application have a configuration xml-file. That file contains more than 50 program settings. At the present time I read and save each program setting separately. I guess It is not effi?iently for such tasks. I need something that can auto-generate a code for load and save my program settings using predefined xml-schema. I found a dataset in Add New Item dialog. Unfortunately, i cannot add new code to dataset1 such as events in set-accessors of properties because of this // Changes to this file may cause incorrect behavior and will be lost if // the code is regenerated. Maybe, there is a tool that allows a user to generate a wrapper for accesing a xml-file ? Such as DataSet1, but with availability to add events.
