• Excel 2003 VSTO convert to PDF

  - by KClough

  I have an excel workbook vsto solution that needs to generate a pdf copy of one of its sheets as output. I have a license for abcdpdf .net and tried outputting to html, then using abcpdf to convert the html to pdf, but the excel html markup tries to emulate excel with all 4 worksheets with horrible markup. It also messes up the colors (silver background across entire workbook). Any suggestions? Here is the code I'm currently using to generate the html file: FileInfo excelDoc = new FileInfo(Globals.ThisWorkbook.Path + @"\Document.html"); Globals.Sheet2.SaveAs(excelDoc.FullName, Excel.XlFileFormat.xlHtml, missing, missing, false, false, Excel.XlSaveAsAccessMode.xlNoChange, missing, missing, missing); If I hack away some of the html header tags manually, I can get abcdpf to accept it, but the formatting is a bit off and this solution seems sub optimal. Thanks in advance.

• Good piece of software that can manage the creation of complex web forms, including reporting, etc?

  - by Callum

  I have some clients who are requesting for some of their reasonably complex paper-based forms to be converted in to web forms. There's straight Q&A text input stuff, there's questions based around checkboxes, radio boxes, select boxes, maybe the occasional attached image, there's data that has to be entered in a tabular fashion, etc. I am deciding whether I should build a "platform" with properly normalised tables to store all types of form data. But before that, I thought I had better check and see if there is anything like that already on the market. I am looking for a product that can: * Easily create web forms of all types * Store all data in a database * Extensive reporting capability I have had a bit of a look around but there's not a whole lot I can see. Does anyone have any suggestions? Thanks.

• Determine if a url matches a Route, and pull out the terms if it does

  - by Kevin Montrose

  I've got a big old log file I'm trying to break down in terms of routes. Essentially, I'm getting input of a path (/questions/31415 for example) and a list of all the registered Routes. What I want out is a Route and the parameters specified in the route (so in, /questions/{id}/{answer} I'd get id and answers out). I've got a working solution that basically generates a nasty bit of regex on the fly with named groups to do matching and parsing all-in-one. My gut tells me this is a brittle way to do it, and frankly there has to be a better way, right?

• Can PyAMF support service deployment by way of the filesystem?

  - by Chris R

  I'm evaluating PyAMF to replace our current PHP (ugh) AMF services framework, and I'm unable to find the one crucial piece of information that would allow me to provide a compelling use case for changing over: Right now, new PHP AMF services are deployed simply by putting the .php files in the filesystem; the next time they're accessed, the new service is in play. Removal of a service is as simple as deleting the .php file that provided it, and updating it is correspondingly simple. I need that same ease-of-deployment from PyAMF. If we have to rewrite our installers to deploy these services, it'll be a nonstarter. So, what I need to know is, can PyAMF support new service discovery by way of the filesystem, can it support service upgrading and removal by way of same, and if so, what is the best way to set it up to do this? I'm open to any of the various server options; I can easily have cherrypy, django, whatever installed and running on its own, and even -- with a bit more sturm nd drang -- have mod_python or mod_wsgi made available.

• Creating a proper CMS thoughts

  - by dallasclark

  I'm just about to expand the functionality of our own CMS but was thinking of restructuring the database to make it simpler to add/edit data types and values. Currently, the CMS is quite flat - the CMS requires a field in the database for every type of stored value. The first option that comes to mind is simply a table which keeps the data types (ie: Address 1, Suburb, Email Address etc) and another table which holds values for each of these data types. Just like how Wordpress keeps values in the 'options' table, serialize would be used to store an array of values. The second option is how Drupal works, the CMS creates tables for every data type. Unlike Wordpress, this can be a bit of an overkill but really useful for SQL queries when ordering and grouping by a particular value. What's everyone's thoughts?

• pasteHTML removes markup

  - by ullmark

  I am writing a plugin to an old IE-only WYSIWYG-editor which resides in an old CMS. I've created a plugin that opens an popup where the user kan enter the url of an youtube clip. The popup then creates the corrent <object..><param..> markup for the embed and uses Internet Explorers pasteHTML function; var range = plugin.editorDocument.selection.createRange(); var embedHtml = OpenDialog(dialogUrl, null, 400, 200); if (!embedHtml) { return; } range.pasteHTML(embedHtml); I know it's missing a bit of information about some of the variables but you get the picture. The problem is that the <param>-tags gets removed when i run the pasteHTML. I wonder if anyone have an idea of fixing this, and letting me keep my param-tags

• A Question About Embedding HTML In PHP

  - by Brian

  Hello all Some time ago I read a posting on a board where the person was talking poorly about people that have HTML embedded/within their PHP. I do quite a bit of PHP development but I still interleave HTML and PHP in the same document. Is there a better way to do this, am I doing it wrong? I know that in JSP/JSF they use an XML document with namespaces to insert their HTML code so I was wondering if there was a similar function that PHP uses that I should be taking advantage of. Thanks for taking the time to read. :-)

• Problem with Scrolling UITableView

  - by HiGuy Smith

  Hello, I have a navigation-based application that has a scrolling UITableView filled with the contents of a directory. Somehow, when I try to scroll a new cell into view, the application crashes. I have determined that it goes down to these lines of code in - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {: NSString *cellText = [contentArray objectAtIndex:indexPath.row]; cell.textLabel.text = cellText; Now why this is crashing, I don't know. contentArray is a NSArray with the table data. If you need a bit more code to tell: - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [contentArray count]; } Please help me with this problem, HiGuy

• Injecting an XML fragment into the current document from an external file

  - by makenai

  I'm currently parsing an XML file using REXML and trying to come up with a way of inserting an XML fragment from an internal file. Currently, I'm using some logic like the following: doc.elements.each('//include') do |element| handleInclude( element ) end def handleInclude( element ) if filename = element.attributes['file'] data = File.open( filename ).read doc = REXML::Document.new( data ) element.parent.replace_child( element, doc ) end end Where my XML looks like the following: <include file="test.xml" /> But this seems a little bit clunky, and I'm worried that REXML might not always parse XML fragments correctly due to absence of a proper root node in some cases. Is there a better way of doing this? Concern #2: REXML seems not to pick up my changes after I replace elements. For example, after making a change: doc.elements.each('rootNode/*') do |element| end ..picks up neither the original element I replaced, nor the one I replaced it with. Is there some trick to getting REXML to rescan its' tree?

• Visual Studio 2010 Database Projects: Are there any videos/tutorials or comments about the new Datab

  - by Mark Redman

  I have recently upgraded to Visual Studio 2010. I have kept database projects separate to application projects. The database project was converted from and old DPR project and added a whole lot of additional folder. I deleted those, but now I suspect I need to recreate the project as these new projects work very differently. Now that I have need to update scripts, it seems I can even paste new SQL files into the project so am a bit stuck. Are there any tutorials / walkthrough that show the basics on starting and creating a database project? Or even better a video? Also if there are any tips and tricks or comments on this, I will be happy to hear them?

• How can I determine if jquery tab is shown because of user click or from tab rotation

  - by Richard Edwards

  I've been using the jQuery UI tabs for a bit now and an interesting request has come up. The current tab setup is using the rotation feature. I need to find a way to determine if the tab is shown because of the result of the rotation itself, or because a user physically clicked the tab. I've wired up all of the standard events, show and select and they fire regardless of the source of the tab change. Does anyone have any ideas? Basically I'd like to do something additional if the user clicked the tab, but not if the tab changes by itself via the rotation. If I wire up the click even to the tabs themselves it doesn't seem to get fired at all, I'm assuming because the tabs widget is using that event itself.

• DB Design Question

  - by hazimdikenli

  I am designing an Org Chart, model is almost ready and simplified a bit for clarity here. OrgUnit (OrgUnitId, Name, ReportsToOrgUnitId, ...) OrgUnitJobs (OrgUnitJobId, OrgUnitId, JobName, ReportsToOrgUnitJobId, ... ,IsJobGroup) Employee (EmployeeId, ........) OrgUnitJobEmployee (OrgUnitJobId, EmployeeId, AssignedDate, .....,) so I want to know every OrgUnit's ManagerEmployee (should have one), and Employees can have more than one job, but one of them has to be the main job, so I know whats his manager and other stuff. This is going to support a little workflow behind the scnese, so that is why it is not a very simple Org chart Model. so what would you do, would you add properties like (IsManager property to OrgUnitJobs model) or add ManagerOrgUnitJobId to OrgUnitModel. and why? Likewise, for employees would you add IsPrimaryJob property to OrgUnitJobEmployee model, or add PrimaryJobId to Employee Model.

• Compare values for audit trail

  - by kagaku

  I'm attempting to develop an audit trail/tracking solution for an existing database written in PLSQL/PHP - however I'm still unsure as of yet on an easy (to implement and maintain) solution for tracking changes to fields/values. For instance, the project tracking portion of the DB APP tracks over 200 fields and ideally I'd like a nice way to show a history of changes, such as: 5/10/2010 - Project 435232 updated by John Doe Changed Project Name (Old: Test Project; New: Super Test Project) Changed Submission Date (Old: 5/10/2010; New: 5/11/2010) Changed Description (Old: This is an example!; New: This is a test example) Essentially for each field (db column) it would output a new line to show the old/new values. So far my current idea is saving the current version of the data to a temporary table, updating the primary table with the new data then loading each row into an array and doing an array compare to determine the differences. This seems a bit convoluted, and if there is an easier method I'd love to know it. Any ideas or suggestions are much appreciated!

• Disable Ctrl-Alt-Del and shutdown for kiosk

  - by acidzombie24

  I finished an app for a client. After talking for a bit he would like me to do an additional app or recommend one for their kiosk. The client would like a way to prevent the computer from shutting down. They like to disable Ctrl+Alt+Delete (also so processes cant be killed), Alt+F4 to close their browser and no windows button to make the start menu pop up for the user to click or use keyboard to shutdown. Obviously there should be a way to unlock it I told them i'll look into it but they really don't need it. They are using Windows 7. Is there a WinAPI call I can use or an already existing app or a lib to do this?

• Find what unknown function does in C using gdb

  - by Gary

  Hi, I have a function m(int i, char c) which takes and returns a char between "-abc...xyz" and also takes an integer i. Basically I have no way to see the source code of the function but can call it and get the return value. Using gdb/C, what's the best way to decipher what the function actually does? I've tried looking for patterns using consecutive chars and integer inputs but have come up with nothing yet. If it helps, here are some results of testing the return values, with the first two bits being the arguments and the last bit being the return value: 0 a i 0 b l 0 c t 0 d x 0 e f 0 f v 1 a q 1 b i 1 c y 1 d e 2 a a 2 b y 2 c f 2 d n

• Jquery autocomplete for input form, using Textpattern category list as a source

  - by John Stephens

  I'm using the Textpattern CMS to build a discussion site-- I have a firm grasp of XHTML and CSS, as well as Textpattern's template language, but PHP and Javascript are a bit beyond my cunning. On the input form to begin a new topic, users need to select a category from a list of over 5,000 options. Using the HTML select-type input element is very unwieldy, but it works. I would like to use some kind of Javascript magic to display a text-type input element that will read user input and display matches or autocomplete from the available categories, passing the required option's value into the appropriate database field. I've seen several autocomplete plugins for jquery, but the instructions presuppose that you understand how Javascript works. As I mentioned above, it's easy for me to generate the category list as a select-type input element, and I can hide that element using CSS. Is it possible to control select-list input using an autocomplete mechanism in a text-type input element? How would I do that?

• Mercurial - revert back to old version and continue from there

  - by Paolo

  I'm using mercurial locally for a project (it's the only repo there's no pushing/pulling to/from anywhere else). To date it's got a linear history. However, the current thing I'm working on I've now realised is a terrible approach and I want to go back to the version before I started it and implement it a different way. I'm a bit confused with the branch / revert / update -C commands in Mercurial. Basically I want to revert to version 38 (currently on 45) and have my next commits have 38 as a parent and carry on from there. I don't care if revisions 39-45 are lost for ever or end up in a dead-end branch of their own. Which command / set of commands do I need?

• Convert Hexadecimal String to Data

  - by AriX

  Hi Stack Overflow, I have found a whole lot of different solutions to this problem, but not all of them work, and a lot of them seem somewhat hacky and inefficient. Basically I have a string of hexadecimal data (i.e. "55 AA 41 2A 00 94 55 AA BB BB 00 FF") which I would like to convert to raw data. What is the best way to do this? UPDATE: Vicky's solution worked great for me, but I changed it to work with hexadecimal strings that don't have spaces in between and changed the style a bit. int i = 0; char *hexString = "55AA412A009455AABBBB00FF" char *hexPtr = hexString; unsigned int *result = calloc(strlen(hexString)/2 + 1, sizeof *result); while (sscanf(hexPtr, "%02x", &result[i++])) { hexPtr += 2; if (hexPtr >= hexString + strlen(hexString)) break; } return result;

• C++ defines for a 'better' Release mode build in VS

  - by darid

  I currently use the following preprocessor defines, and various optimization settings: WIN32_LEAN_AND_MEAN VC_EXTRALEAN NOMINMAX _CRT_SECURE_NO_WARNINGS _SCL_SECURE_NO_WARNINGS _SECURE_SCL=0 _HAS_ITERATOR_DEBUGGING=0 My question is what other things do fellow SOers use, add, define, in order to get a Release Mode build from VS C++ (2008,2010) to be as performant as possible? btw, I've tried PGO etc, it does help a bit but nothing that comes to parity, also I'm not using streams, the C++ i'm talking about its more like C but making use of templates and STL algorithms. As it stands now very simple code segments flop when compared to what GCC produces on say an equivalent x86 machine running linux (2.6+ kernel) using 02. Side-Note: I believe a lot of the issues relate directly to the STL version (Dinkum) provided by MS. Could people please elaborate on experiences using STLPort etc with VS C++.

• Google app engine - what is the lifecycle of PersistenceManager?

  - by Domchi

  What is the preferred way of using GAE datastore PersistenceManager for web app? GAE instructions are a bit ambiguous on the matter. Do I instantiate PersistenceManagerFactory for each RPC call, or do I use only one factory for all requests? Do I call PMF.get().getPersistenceManager(), or do I call PMF.get().getPersistenceManagerProxy()? Do I close PM after each RPC call, or do I leave it open? What are you guys doing? Furthermore, I'm not certain how GAE handles 30-second-per-request limit. Is it even possible to reference the same PM between requests?

• Mac OS X: java.lang.ClassNotFoundException: com.sun.java.browser.plugin2.DOM

  - by Thilo

  I am trying to use the new LiveConnect features introduced in Java 6 Update 10. Code looks like this (copied from the applet tutorial): Class<?> c = Class.forName("com.sun.java.browser.plugin2.DOM"); Method m = c.getMethod("getDocument", java.applet.Applet.class); Document document = (Document) m.invoke(null, this); But all I am getting is a ClassNotFoundException for the entry-point class. This on the Mac, 10.6, with both Firefox and Safari. Java Plug-in 1.6.0_22 Using JRE version 1.6.0_22-b04-307-10M3261 Java HotSpot(TM) 64-Bit Server VM Is this not implemented on the Mac? Or do I need to configure something? All I need to do is get and set the value of form elements on the page, so I would be fine with an older (pre-6u10) API if that works better.

• Understanding pattern matching with cons operator

  - by Mathias

  In "Programming F#" I came across a pattern-matching like this one (I simplified a bit): let rec len list = match list with | [] -> 0 | [_] -> 1 | head :: tail -> 1 + len tail;; Practically, I understand that the last match recognizes the head and tail of the list. Conceptually, I don't get why it works. As far as I understand, :: is the cons operator, which appends a value in head position of a list, but it doesn't look to me like it is being used as an operator here. Should I understand this as a "special syntax" for lists, where :: is interpreted as an operator or a "match pattern" depending on context? Or can the same idea be extended for types other than lists, with other operators?

• iPhone: Best Method for Passing Data to and from a Server

  - by SAPNA

  I am developing an iPhone application that downloads data from a website. The website database is implemented in SQL and the site itself uses the classic ASP interface. I am unsure as to which method would be best for transferring data to and from the server. Both JSON and SOAP require XML processing and I'm not sure how that affects performance or which of those two is best. What would be the best method in general for data transfer given the server configuration we currently have? I very new to this field and I'm a bit confused. Any help would be appreciated.
