• Indesign and XML - how to auto flow into multiple pages with differing styles?

  - by MetaDan

  Hi guys, I've got a bit of a problem at the moment. I'm trying to work with indesign (cs3) and xml. Basically i have a template which is has 1 master dps, both pages have the same data (fields 1-5) but one is left aligned, one right - hence mildly different paragraph styles. What i want to be able to do is import xml and have indesign flow the data from the individual nodes into many pages. eg xml format: root day field1 field2 field3 field4 field5 day field1 field2 field3 field4 field5 day ... I can almost make this work by tagging the frames on the master pages, then creating pages and importing the xml, however it only flows the first 2 nodes into the pages reptitively for the total count of all the nodes. I can also almost make it work by creating a page from the untagged masters and then tagging the frames with the field1-5 tags then importing the xml. This populates the first page, however i then can't find a way to make the rest of the data flow into new pages... Am I missing something? Am I being a complete dumbass? If anyone can offer any help it will be greatly appreciated...

• Creating futures using Apple's GCD

  - by jer

  I'm working on a library which implements the actor model on top of Grand Central Dispatch (specifically the C level API libdispatch). Basically a brief overview of my system is as such: Communication happens between actors using messages Multicast communication only (one actor to many actors) Senders and receivers are decoupled from one another using a blackboard where messages are pushed to. Messages are sent in the default queue asynchronously using dispatch_group_async() once a message gets pushed onto the blackboard. I'm trying to implement futures in the language right now, so I've created a new type which holds some information: A group of its own The value being 'returned' However, I have a problem since dispatch_block_t is of type void (^)(void) so it doesn't return anything. So my idea of in my future_new() function of setting up another group which can be used to execute a block returning a result, which I can store in my "value" member in my future_t structure, isn't going to work. The rest of the futures implementation is very clear, except it all depends on being able to get the value into the future back from the actor, acting on the message. When using the library, it would greatly reduce its usefulness if I had to ask users (and myself) to be aware when futures were going to be used by other parts of the system—It just isn't practical. I'm wondering if anyone can think of a way around this?

• Silverlight Socket Constantly Returns With Empty Buffer

  - by Benny

  I am using Silverlight to interact with a proxy application that I have developed but, without the proxy sending a message to the Silverlight application, it executes the receive completed handler with an empty buffer ('\0's). Is there something I'm doing wrong? It is causing a major memory leak. this._rawBuffer = new Byte[this.BUFFER_SIZE]; SocketAsyncEventArgs receiveArgs = new SocketAsyncEventArgs(); receiveArgs.SetBuffer(_rawBuffer, 0, _rawBuffer.Length); receiveArgs.Completed += new EventHandler<SocketAsyncEventArgs>(ReceiveComplete); this._client.ReceiveAsync(receiveArgs); if (args.SocketError == SocketError.Success && args.LastOperation == SocketAsyncOperation.Receive) { // Read the current bytes from the stream buffer int bytesRecieved = this._client.ReceiveBufferSize; // If there are bytes to process else the connection is lost if (bytesRecieved > 0) { try { //Find out what we just received string messagePart = UTF8Encoding.UTF8.GetString(_rawBuffer, 0, _rawBuffer.GetLength(0)); //Take out any trailing empty characters from the message messagePart = messagePart.Replace('\0'.ToString(), ""); //Concatenate our current message with any leftovers from previous receipts string fullMessage = _theRest + messagePart; int seperator; //While the index of the seperator (LINE_END defined & initiated as private member) while ((seperator = fullMessage.IndexOf((char)Messages.MessageSeperator.Terminator)) > 0) { //Pull out the first message available (up to the seperator index string message = fullMessage.Substring(0, seperator); //Queue up our new message _messageQueue.Enqueue(message); //Take out our line end character fullMessage = fullMessage.Remove(0, seperator + 1); } //Save whatever was NOT a full message to the private variable used to store the rest _theRest = fullMessage; //Empty the queue of messages if there are any while (this._messageQueue.Count > 0) { ... } } catch (Exception e) { throw e; } // Wait for a new message if (this._isClosing != true) Receive(); } } Thanks in advance.

• Magic function `bash ` not found

  - by inspectorG4dget

  I have a bunch of simulations that I want to run on a high-performance cluster, on which I should make reservations to get computing time. Since the reservations are bounded by time, I am developing an automation script that I can scp into the cluster and run. This script will then download the relevant simulation files, run them, and upload the results. Part of this automation script is in bash (cp, scp, etc) and the rest is in python. In order to develop this automation, I am using an IPython notebook. So far, I've coded all the python automation stuff in my IPython notebook and am trying to write the bash part of it now. However, it seems that the magic %%bash doesn't work in my IPython notebook. I get the following error when I have this code in my cell: Cell %%bash echo hi Error File "<ipython-input-22-62ec98e35224>", line 3 echo hi ^ SyntaxError: invalid syntax On a whim, I tried this: Cell %%bash print "hi" Error hi ERROR: Magic function `bash` not found. So I tried this with %%system, %%! and %%shell. But none of those work; they all give me the same error. Why is this happening? How can I fix this?

• How to Perform Continues Iteration over Shared Dictionary in Multi-threaded Environment

  - by Mubashar Ahmad

  Dear Gurus. Note Pls do not tell me regarding alternative to custom session, Pls answer only relative to the Pattern Scenario I have Done Custom Session Management in my application(WCF Service) for this I have a Dictionary shared to all thread. When a specific function Gets called I add a New Session and Issue SessionId to the client so it can use that sessionId for rest of his calls until it calls another specific function, which terminates this session and removes the session from the Dictionary. Due to any reason Client may not call session terminator function so i have to implement time expiration logic so that i can remove all such sessions from the memory. For this I added a Timer Object which calls ClearExpiredSessions function after the specific period of time. which iterates on the dictionary. Problem: As this dictionary gets modified every time new client comes and leaves so i can't lock the whole dictionary while iterating over it. And if i do not lock the dictionary while iteration, if dictionary gets modified from other thread while iterating, Enumerator will throw exception on MoveNext(). So can anybody tell me what kind of Design i should follow in this case. Is there any standard pattern available.

• How To Share Information Between Django and Javascript?

  - by Randy

  So I am pretty new to both Django and Javascript (I am using JQuery) and I am wondering if I am doing a hack or if there are more slick ways to send client-side displayed database ids to the django server-side. Here is my process: I have a dataTable (http://datatables.net) that I am displaying rows of data by using the bProcessing option to use AJAX to retrieve records from the database. The URL in my urls.py is something like: url(r'^assets/activitylog/(?P<cid>.*)$', views.getActivityTable_ajax, name="activitylog_table"), and my dataTable ajax-relavant code is something like: "sAjaxSource": "/assets/activitylog/" + getIDFromHTML(), where the javascript function getIDFromHTML() grabs <cid> that is used by the Django view is simply: function getIDFromHTML(){ // Simply return the text in the #release_id div element from the HTML return $("#release_id").html(); }; This is the part that seems "hacky" to me. I am inserting into my template code the database id that I am using in the datatables URL (with display:none in the css) just so I can pass it back to the view. Most of this is necessitated because one cannot use django template tags in the javascript code unless the code is embedded into the HTML itself, which I am not (and will not) do. The only other thing that I have found is to change the URL to get rid of the parameter passed in to: url(r'^assets/activitylog', views.getActivityTable_ajax, name="activitylog_table"), and change the view code to: def getActivityTable_ajax(request): """Returns the activity for a given pid from HTTP GET ajax reqest""" pid = int(urlparse.urlparse(request.META['HTTP_REFERER']).path.split('/')[-1]) # rest of view code here... since the id that I need is on the end of this referer url. This way I don't have to monkey around with embedding the hidden database id into the HTML and passing it back to via ajax the the table population view code. Is it okay to use HTTP_REFERER in the request object in this manner? Am I going about this in the totally wrong way? Thanks in advance!

• toggleClass messing something up.

  - by Mathias Nielsen

  Hi I am using playing around with the Pretty-checkboxes-plugin and have a problem. The plugin can be seen here http://aaronweyenberg.com/90/pretty-checkboxes-with-jquery As you can see, this uses two links to select and deselect. I want it to only use one link and then change the class to make it work the other way the next time it is clicked. It should be simple enough. I have been trying to get it working with toggleClass. I simply put in the toggleClass statement so the code looks like so: $(document).ready(function() { /* see if anything is previously checked and reflect that in the view*/ $(".checklist input:checked").parent().addClass("selected"); /* handle the user selections */ $(".checklist .checkbox-select").click( function(event) { event.preventDefault(); $(this).parent().addClass("selected"); $(this).parent().find(":checkbox").attr("checked","checked"); $(this).toggleClass("checkbox-select checkbox-deselect"); } ); $(".checklist .checkbox-deselect").click( function(event) { event.preventDefault(); $(this).parent().removeClass("selected"); $(this).parent().find(":checkbox").removeAttr("checked"); $(this).toggleClass("checkbox-select checkbox-deselect"); } ); }); This works to some extend. The classes toggle just fine, but the rest of the code only works the first time it is run. All subsequent clicks just toggle the class og the link and nothing else. Does anyone have any idea why this is?

• Implementing IXmlSerializable on a generated class that has XmlTypeAttribute

  - by Josh

  Basically, the initial problem is I need to make a boolean value serialize as 0 or 1. The solution I found was to implement IXmlSerializable, which I did. Unfortunately the class I'm trying to serialize is generated code off a schema and has an XmlTypeAttribute on it. When I try to (de)serialize the object with the XmlSerializer created in the usual manner ( new XmlSerializer(type)) it throws this exception: System.InvalidOperationException: Only XmlRoot attribute may be specified for the type ______ Please use XmlSchemaProviderAttribute to specify schema type. Two options come to mind immediatly: 1) remove the attribute in the generated code. This change would have to be made every time the code was re-generated. 2) Use an XmlAttributeOverrides object when creating the serializer to remove the attribute. This would require the rest of the code base to "know" that it needs to override that attribute. Also, the exception thrown gives absolutly no clue as to what needs to be done to fix it. Both options kinda stink. Is there a third option?

• NSTableView selection & highlights

  - by Christian

  I have a NSTableView as a very central part of my Application and want it to integrate more with the rest of it. It has only one column (it's a list) and I draw all Cells (normal NSTextFieldCells) myself. The first problem is the highlighting. I draw the highlight myself and want to get rid of the blue background. I now fill the whole cell with the original background color to hide the blue background, but this looks bad when dragging the cell around. I tried overriding highlight:withFrame:inView: and highlightColorWithFrame:inView: of NSCell but nothing happened. How can I disable automatic highlighting? I also want all rows/cells to be deselected when I click somewhere outside my NSTableView. Since the background / highlight of the selected cell turns gray there must be an event for this, but I can't find it. I let my cells expand on a double click and may need to undo this. So getting rid of the gray highlight is not enough. EDIT: I add a subview to the NSTableView when a cell gets double clicked and then resignFirstResponder of the NSTableView gets called. I tried this: - (BOOL)resignFirstResponder { if (![[self subviews] containsObject:[[self window] firstResponder]]) { [self deselectAll:self]; ... } return YES; } Besides that it's not working I would need to implement this method for all objects in the view hierarchy. Is there an other solution to find out when the first responder leaves a certain view hierarchy?

• hiding buttons in master page

  - by pankaj

  Hi, I am working on an app where i am having some linkbuttons in master page. I want to display them depending upon the authorization given to them once they logs in. I have initially made all of them visible false and then i am checking the authorisation in the aspx.cs class of master page. I make the link button visible depending upon the right granted to the user. But it is making all the link buttons visible. Instead it should only make two of them visible and rest should be hidden. Following is my code from MasterPage.aspx.cs: ArrayList arrlstUserRoles = new ArrayList(); arrlstUserRoles = (ArrayList)Session["Roles"]; for (int j = 0; j < arrlstUserRoles.Count; j++) { if (int.Parse(arrlstUserRoles[j].ToString()) == 1) { lbtnRetailer.Visible = true; } else if (int.Parse(arrlstUserRoles[j].ToString()) == 2) { lbtnCategory.Visible = true; } else if (int.Parse(arrlstUserRoles[j].ToString()) == 3) { lbtnCouponTemplate.Visible = true; } else if (int.Parse(arrlstUserRoles[j].ToString()) == 4) { //lbtnStoreManagement.Visible = true; } else if (int.Parse(arrlstUserRoles[j].ToString()) == 5) { lbtnStoreManagement.Visible = true; } else if (int.Parse(arrlstUserRoles[j].ToString()) == 6) { lbtnContentManagement.Visible = true; } else if (int.Parse(arrlstUserRoles[j].ToString()) == 7) { //lbtnStoreManagement.Visible = true; } }

• Understanding Wordpress database schema - querying from 3rd party app

  - by deceze

  Is there an easy way to grab the latest posts out of a Wordpress wp_posts table using a simple SQL query? I have a Wordpress 2.9.2 installation as part of, but separate from, a larger system. It has a customized theme to look like the rest of the site but has otherwise nothing to do with it. I want to display the latest handful of headlines of posts made using Wordpress on a site of that other system. Preferably I do not want to mess around with importing any of the Wordpress library files. Looking at the database structure I can't see an easy, straight-forward query to simply get the latest revision of the latest posts. The post_status can either be "post" or "inherit", the post_type "post" or "revision" and the parent "0" or the id of the original post of a revision. I can't figure out how to reliably filter different revisions of the same post, drafts, attachments and pages out of this mess and just get the latest revision of the latest posts. I'm aware that the database schema is subject to change in subsequent versions of Wordpress, so shouldn't be relied upon, but that's a minor concern, since it's such a minor feature that could easily be fixed. If I understood how that database is supposed to work, that is.

• creating matrix with probabilities

  - by John Chan

  Hi all, I want to generate a matrix of NxN to test some code that I have where each row contains floats as the elements and has to add up to 1 (i.e. a row with a set of probabilities). Where it gets tricky is that I want to make sure that randomly some of the elements should be 0 (in fact most of the elements should be 0 except for some random ones to be the probabilities). I need the probabilities to be 1/m where m is the number of elements that are not 0 within a single row. I tried to think of ways to output this, but essentially I would need this stored in a C++ array. So even if I output to a file I would still have the issue of not having it in array as I need it. At the end of it all I need that array because I want to generate a Market Matrix file. I found an implementation in C++ to take an array and convert it to the market matrix file, so this is what I am basing my findings on. My input for the rest of the code takes in this market matrix file so I need that to be the primary form of output. The language does not matter, I just want to generate the file at the end (I found a way mmwrite and mmread in python as well) Please help, I am stuck and not really sure how to implement this.

• How to optimize Conway's game of life for CUDA?

  - by nlight

  I've written this CUDA kernel for Conway's game of life: global void gameOfLife(float* returnBuffer, int width, int height) { unsigned int x = blockIdx.x*blockDim.x + threadIdx.x; unsigned int y = blockIdx.y*blockDim.y + threadIdx.y; float p = tex2D(inputTex, x, y); float neighbors = 0; neighbors += tex2D(inputTex, x+1, y); neighbors += tex2D(inputTex, x-1, y); neighbors += tex2D(inputTex, x, y+1); neighbors += tex2D(inputTex, x, y-1); neighbors += tex2D(inputTex, x+1, y+1); neighbors += tex2D(inputTex, x-1, y-1); neighbors += tex2D(inputTex, x-1, y+1); neighbors += tex2D(inputTex, x+1, y-1); __syncthreads(); float final = 0; if(neighbors < 2) final = 0; else if(neighbors 3) final = 0; else if(p != 0) final = 1; else if(neighbors == 3) final = 1; __syncthreads(); returnBuffer[x + y*width] = final; } I am looking for errors/optimizations. Parallel programming is quite new to me and I am not sure if I get how to do it right. The rest of the app is: Memcpy input array to a 2d texture inputTex stored in a CUDA array. Output is memcpy-ed from global memory to host and then dealt with. As you can see a thread deals with a single pixel. I am unsure if that is the fastest way as some sources suggest doing a row or more per thread. If I understand correctly NVidia themselves say that the more threads, the better. I would love advice on this on someone with practical experience.

• WCF code generation for large/complex schema (HR-XML/OAGIS) - is there an alternative?

  - by Sasha Borodin

  Hello, and thank you for reading. I am implementing a WCF Service based on a predefined specification (HR-XML 3.0). As such, I am starting with the schema, and working my way back to code. There are a number of large Schema documents (which import yet more Schema documents) related to my implementation, provided by this specification. I am able to generate code using xsd.exe, by supplying the "main" and "supporting" xsd files as arguments. But there are several issues, and I am wondering if this is the right approach. there are litterally hundreds of classes - the code file is half a meg in size duplicate classes (ex. Type, Type1 - which both represent the same type) there are classes declared as inheriting from a base class, but that base class is not generated/defined I understand that there are limitations to the types of Schema supported by svcutil.exe/xsd.exe when targeting the DataContractSerializer and even XmlSerializer. My question is two-fold: Are code generation "issues" fairly common when dealing with larger, modular xsd files? Has anyone had success with generating data contracts from OAGIS or HR-XML schema? Given the above issues, are there better approaches to this task, avoiding generating code and working with concrete objects? Does it make better sence to read and compose a SOAP message directly, while still taking advantage of the rest of the WCF framework? I understand that I am loosing the convenience of working with .NET objects, and the framekwork-provided (de)serialization; given these losses, would it still be advantageous to base my Service on WCF? Is there some "middle ground" between working with .NET types and pure XML? Thank you very much! -Sasha Borodin DFWHC.org

• Python: Convert format string to regular expression

  - by miracle2k

  The users of my app can configure the layout of certain files via a format string. For example, the config value the user specifies might be: layout = '%(group)s/foo-%(locale)s/file.txt' I now need to find all such files that already exist. This seems easy enough using the glob module: glob_pattern = layout % {'group': '*', 'locale': '*'} glob.glob(glob_pattern) However, now comes the hard part: Given the list of glob results, I need to get all those filename-parts that matched a given placeholder, for example all the different "locale" values. I thought I would generate a regular expression for the format string that I could then match against the list of glob results (or then possibly skipping glob and doing all the matching myself). But I can't find a nice way to create the regex with both the proper group captures, and escaping the rest of the input. For example, this might give me a regex that matches the locales: regex = layout % {'group': '.*', 'locale': (.*)} But to be sure the regex is valid, I need to pass it through re.escape(), which then also escapes the regex syntax I have just inserted. Calling re.escape() first ruins the format string. I know there's fnmatch.translate(), which would even give me a regex - but not one that returns the proper groups. Is there a good way to do this, without a hack like replacing the placeholders with a regex-safe unique value etc.? Is there possibly some way (a third party library perhaps?) that allows dissecting a format string in a more flexible way, for example splitting the string at the placeholder locations?

• Dynamically compose ASP MVC view based on context

  - by robertFall

  I have several views that are composed of several partial views based on context. For example, we have a Project view that shows all the details of a project, which includes the scalar values, name etc, and also all the assigned employees, tasks and/or clients. The problem I have is that certain types of project have all of the above sections while others have only two or even on section, ie. details only. What is the best way to compose the Projects master view? I don't want to have logic to check the project in the view. Is there a way to compose a view in code by programatically rendering the relevant partials and ignoring the rest? Otherwise are there any other ideas how to do this in a maintainable way? I could of course just render the partials using if statements to check if they apply, but that way the view contains VERY important logic. In another situation we want to use this method to display content based on the type of subscription a user has. Thanks!

• SSIS - Skip Missing Files

  - by Greg

  I have a SSIS 2008 package that calls about 10 other SSIS packages (legacy issues, don't ask). Each of those child packages loads a specific file into a table. But sometimes one or more of these input files will be missing. How can I let a child package fail (because a file is missing) but let the rest of the parent package keep on running? I've tried increasing the maximum error count on the parent package, the tasks in the parent package that call each child, and in the child package itself. None of that seemed to make any difference. I still get this error when I run it with a file missing: SSIS Warning Code DTS_W_MAXIMUMERRORCOUNTREACHED. The Execution method succeeded, but the number of errors raised (2) reached the maximum allowed (1); resulting in failure. This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors. Edit: failpackageonfailure and faulparentonfailure are already all set to false everywhere.

• Inconsistent table width when hideing/showing a set of columns

  - by Salman A. Kagzi

  I have got a an HTML table of around 40+ columns. To make this table fit in the screen and have the data in a re presentable format we have section in this table. i.e. there are some column that are always visible and the remainder a made visible when s specific radio button (describing a section) is selected. Each radio button is associated to different number of columns. We show/hide a column by setting/removing "display:none" style in all the cell under that column. This all works Just fine. Now the real problem is with the width of the columns in this table. I cant use fixed with with pixel settings. I have tried using the percentage setting by giving 50% to the always visible part and rest 50% is divided between the column in a section. But I am unable to get a fixed behavior i.e. the size of the table columns across IE & FF. Some columns are just right while some are really huge. How can I get the table to give consistent column width across browsers?

• Fill parent container

  After several hours of design battle I come to you for a hand. I am building a website for a night club as you can see. I can't get stretch the centered area (bordered by yellow color) to the bottom of the page where the footer start (the footer is the green top-bordered div).

• Managing inverse relationships without CoreData

  - by Nathaniel Martin

  This is a question for Objective-J/Cappuccino, but I added the cocoa tag since the frameworks are so similar. One of the downsides of Cappuccino is that CoreData hasn't been ported over yet, so you have to make all your model objects manually. In CoreData, your inverse relationships get managed automatically for you... if you add an object to a to-many relationship in another object, you can traverse the graph in both directions. Without CoreData, is there any clean way to setup those inverse relationships automatically? For a more concrete example, let's take the typical Department and Employees example. To use rails terminology, a Department object has-many Employees, and an Employee belongs-to a Department. So our Department model has an NSMutableSet (or CPMutableSet ) "employees" that contains a set of Employees, and our Employee model has a variable "department" that points back to the Department model that owns it. Is there an easy way to make it so that, when I add a new Employee model into the set, the inverse relationship (employee.department) automatically gets set? Or the reverse: If I set the department model of an employee, then it automatically gets added to that department's employee set? Right know I'm making an object, "ValidatedModel" that all my models subclass, which adds a few methods that setup the inverse relationships, using KVO. But I'm afraid that I'm doing a lot of pointless work, and that there's already an easier way to do this. Can someone put my concerns to rest?

• Sourcing a shell script, while running with sudo

  - by WishCow

  I would like to write a shell script that sets up a mercurial repository, and allow all users in the group "developers" to execute this script. The script is owned by the user "hg", and works fine when ran. The problem comes when I try to run it with another user, using sudo, the execution halts with a "permission denied" error, when it tries to source another file. The script file in question: create_repo.sh #!/bin/bash source colors.sh REPOROOT="/srv/repository/mercurial/" ... rest of the script .... Permissions of create_repo.sh, and colors.sh: -rwxr--r-- 1 hg hg 551 2011-01-07 10:20 colors.sh -rwxr--r-- 1 hg hg 1137 2011-01-07 11:08 create_repo.sh Sudoers setup: %developer ALL = (hg) NOPASSWD: /home/hg/scripts/create_repo.sh What I'm trying to run: user@nebu:~$ id uid=1000(user) gid=1000(user) groups=4(adm),20(dialout),24(cdrom),46(plugdev),105(lpadmin),113(sambashare),116(admin),1000(user),1001(developer) user@nebu:~$ sudo -l Matching Defaults entries for user on this host: env_reset User user may run the following commands on this host: (ALL) ALL (hg) NOPASSWD: /home/hg/scripts/create_repo.sh user@nebu:~$ sudo -u hg /home/hg/scripts/create_repo.sh /home/hg/scripts/create_repo.sh: line 3: colors.sh: Permission denied So the script is executed, but halts when it tries to include the other script. I have also tried using: user@nebu:~$ sudo -u hg /bin/bash /home/hg/scripts/create_repo.sh Which gives the same result. What is the correct way to include another shell script, if the script may be ran with a different user, through sudo?

• LNK 1104 error to lib file - Continues despite removing includes and links

  A link error to a lib file popped up out of the blue in a c++ application of mine after code was working fine in my last session. Error 1 error LNK1104: cannot open file '..........\Program Files (x86)\FMOD SoundSystem\FMOD Programmers API Windows\api\lib\fmodex_vc.lib' I triple checked my project directories were set up correctly to link to the lib file, that the file existed in said directory and that it was a working version of the .lib. My next step was to remove the includes to the file and the links to bypass the error and work on the rest of my code until the problem was solved. The error remains, however, despite: Commenting out absolutely every include relating to the lib. Commenting out absolutely every line of code dependant on the includes. Removing the directory from VC++ Directories in the project properties. Checking the Additional Library Directories field was also clear of references. To my understanding this should have made the library and related code virtually non-existant to the compiler. What am I missing? The library itself is fmodex_vc.lib - part of the FMOD API for providing sound to interactive applications. Again, the application was working one session, but failed to compile the next. I hadn't touched the code since so this led me to believe some aspect of VS is at fault. I'd like to avoid the time involded in re-installing if possible as I'm on the clock for a review tomorrow evening and there are a few more things I'd like to smooth out before then. If necessary, however, I won't hesitate. Very much appreciate the help.

• Programming time schedule for porting a program.

  - by Lothar

  I'm working on a large program which has an abstracted GUI API. It is very GUI based, many dialogs and a few nasty features which rely heavily on the message flow of the GUI (correct sequences of focus/mouse/active handling etc.) - not easy to port I now want to port it from the currently used FOX Toolkit to native Cocoa/MFC. I give myself a timeframe until the end of the year but my main work will be to continue development work with the existing toolkit, but there is no planned release for end customers before both tasks are done. My question is how should i spend my time? Stop working on the main program and do a 90% port (about 3 month) of the GUI first Splitting everything into smaller sessions of one month each. Assigning Monday/Tuesday to the GUI project and the rest of the week for the app. Finishing the App first, then port. I think there are three arguments which i need to balance. Motivation, i want to see something going on on both projects Brain Input Overflow, both tasks require a lot of detail information in my brain and sometimes enough is just enough. I guess the porting is intervowen so porting would also require a lot of code changes in the existing code and the new code that will be written in the meantime.

• Write raw struct contents (bytes) to a file in C. Confused about actual size written

  - by d11wtq

  Basic question, but I expected this struct to occupy 13 bytes of space (1 for the char, 12 for the 3 unsigned ints). Instead, sizeof(ESPR_REL_HEADER) gives me 16 bytes. typedef struct { unsigned char version; unsigned int root_node_num; unsigned int node_size; unsigned int node_count; } ESPR_REL_HEADER; What I'm trying to do is initialize this struct with some values and write the data it contains (the raw bytes) to the start of a file, so that when I open this file I later I can reconstruct this struct and gain some meta data about what the rest of the file contains. I'm initializing the struct and writing it to the file like this: int esprime_write_btree_header(FILE * fp, unsigned int node_size) { ESPR_REL_HEADER header = { .version = 1, .root_node_num = 0, .node_size = node_size, .node_count = 1 }; return fwrite(&header, sizeof(ESPR_REL_HEADER), 1, fp); } Where node_size is currently 4 while I experiment. The file contains the following data after I write the struct to it: -bash$ hexdump test.dat 0000000 01 bf f9 8b 00 00 00 00 04 00 00 00 01 00 00 00 0000010 I expect it to actually contain: -bash$ hexdump test.dat 0000000 01 00 00 00 00 04 00 00 00 01 00 00 00 0000010 Excuse the newbiness. I am trying to learn :) How do I efficiently write just the data components of my struct to a file?
