• Extract co-ordinates from a vector of co-ordinates and save to file

  - by barsil sil

  I have a vector which contains a list co-ordinates ...x1,y1 ; x2,y2....xn,yn I am trying to extract each individual element which is a co-ordinate and then save them to file as a nice delineated co-ord pair which can be easily read. Or what would be nice i to save them so I can plot something in excel e.t.c (as cols of x and y values). My original vector size is 31, and was originally constructed as vector<vector<Point> > myvector( previous vector.size() ); Thanks !

• Setting foreground color for HSSFCellStyle is always coming out black

  - by Ascalonian

  I am using POI to create an Excel spreadsheet in Java. I have the following code used for creating a header row: HSSFWorkbook wb = new HSSFWorkbook(); HSSFSheet sheet = wb.createSheet("Report"); // some more code HSSFRow row = sheet.createRow(0); HSSFCell cell = row.createCell(cellNumber); HSSFCellStyle cellStyle = wb.createCellStyle(); cellStyle.setFillBackgroundColor(HSSFColor.GREY_25_PERCENT.index); cellStyle.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND); HSSFFont font = wb.createFont(); font.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD); font.setColor(HSSFColor.WHITE.index); cellStyle.setFont(font); cell.setCellStyle(cellStyle); The issue I am having is that setting the fill background color on the cell always comes out black, no matter what color I pick. What am I doing wrong? If I don't use the "setFillPattern" line, no color shows up at all.

• Programming a loopback-device consisting of several files in Linux

  - by dubbaluga

  Hej, it is relatively easy to use a file for emulating a block-device using losetup in Linux: http://www.walkernews.net/2007/07/01/create-linux-loopback-file-system-on-disk-file/ Can anyone please give me a hint on what to look for in case I want to program my own block-device which is based on several files I'm taking content from? For your understanding, I would like to let's say take bytes 1-500 and 1.000-3.000 from file1 and bytes 501-999 and bytes 3.001 to 5.000 from file2 to offer them as a combined block-device. My prefered programming language is Python and I want to write my program in user-space as much as possible. For Windows I found such an implementation. It's called FileDisk and HttpDisk and it can be found here: http://www.acc.umu.se/~bosse/ Thanks in advance and regards, Rainer

• How to customize OOTB workflow emails

  - by Jeff

  How can I make simple format-type customizations to ALL OOTB workflow related emails? I have found that many pre-Sharepoint 2010 posts indicated that OOTB workflow emails are in fact 'alerts', and therefore OOTB workflow emails could be customized using the same technique which is: making a customized version of alerttemplates.xml and even using IAlertNotifyHandler to intercept all alert emails. However, it seems that OOTB workflow and workflow task emails are not affected by changes to my customalerttemplates.xml file (which I do follow with stsadm updatealerttemplates, iisreset, and timer service restart). This is what I used as a guide to customize alerts: http://blogs.msdn.com/b/sharepointdeveloperdocs/archive/2007/12/14/how-to-customizing-alert-emails-using-ialertnotificationhandler.aspx What am I missing? Is there a separate template for workflow emails? Can OOTB workflow emails be customized? Thanks! Jeff

• WPF DataGrid row validation error count

  - by SuperFloh1234

  Hi! I'm currently facing the problem, that I import an Excel file to a DataGrid. This works pretty fine, but after importing the table, I need to know how many rows are invalid. I have applied several validation rules for the different datatypes, and I have an icon in the row header, that shows up if the row is invalid. But since I have more that 10.000 rows in the grid, I don't want scroll all the way through it to find the errors. Any ideas, how to determine the count of invalid rows (and then maybe bind that to a textbox)? Thx

• Regular expression to remove all text except...

  - by Barryman9000

  There may be an easier way, and if there is I'm all for it. However - my ASP.NET page has a TON of controls on it, and I've given them all ID's that start with underscore. I copied all the markup into Notepad++ and I'm trying to find a regular expression that will find everything but the controls and replace it with whitespace. that way I'll have a text file that has all my control names which I'll probably throw into Excel and do some string manipulation to add ".Text = " etc. Any suggestions?

• Oracle - timed sampling from v$session_longops

  - by FrustratedWithFormsDesigner

  I am trying to track performance on some procedures that run too slow (and seem to keep getting slower). I am using v$session_longops to track how much work has been done, and I have a query (sofar/((v$session_longops.LAST_UPDATE_TIME-v$session_longops.start_time)*24*60*60)) that tells me the rate at which work is being done. What I'd like to be able to do is capture the rate at which work is being done and how it changes over time. Right now, I just re-execute the query manually, and then copy/paste to Excel. Not very optimal, especially when the phone rings or something else happens to interrupt my sampling frequency. Is there a way to have script in SQL*Plus run a query evern n seconds, spool the results to a file, and then continue doing this until the job ends? (Oracle 10g)

• Export products and variants from MSSQL

  - by mickyjtwin

  I have a SQL DB that has a table of products, and another table which contains a list of the sku variants of each product if it has one. I want to export all the products and their SKU's into excel. At the moment, I have a helper SQL function which performs the subquery against a product_id and concatenates all the SKU's into a comma-delimited string, e.g: Product Code, Name, SKUs 111 P1 77, 22, 11 Is there an easier way to do this, so that each SKU is a row which the associated product code as well, i.e: Product Code, Name, SKUs 111 P1 77 111 P1 22 111 P1 11

• Why the "mutable default argument fix" syntax is so ugly, asks python newbie

  - by Cawas

  Now following my series of "python newbie questions" and based on another question. Go to http://python.net/~goodger/projects/pycon/2007/idiomatic/handout.html#other-languages-have-variables and scroll down to "Default Parameter Values". There you can find the following: def bad_append(new_item, a_list=[]): a_list.append(new_item) return a_list def good_append(new_item, a_list=None): if a_list is None: a_list = [] a_list.append(new_item) return a_list So, question here is: why is the "good" syntax over a known issue ugly like that in a programming language that promotes "elegant syntax" and "easy-to-use"? Why not just something in the definition itself, that the "argument" name is attached to a "localized" mutable object like: def better_append(new_item, a_list=[].local): a_list.append(new_item) return a_list I'm sure there would be a better way to do this syntax, but I'm also almost positive there's a good reason to why it hasn't been done. So, anyone happens to know why?

• Online chart editor

  - by Alexander Gladysh

  I love to use Google Documents as MS Word and MS Excel replacements for online collaboration. However, now I need to discuss architecture layout for my software. Nothing too fancy, perhaps a little (pseudo-)UML, but mostly basic shapes (rectangles, ellipses etc.) with labels, connected by thin lines or arrows. In olden Windows times I'd go for Visio, and be happy. But now I want to use online tool. Preferably free. No need for code reverse engineering etc., just plain assisted vector drawing. Any advice? What do you use?

• iframe for ad loading good or bad?

  - by Cedar Jensen

  According to Yahoo's "Best Practices for Speeding Up your Site", the pros for using iframes: Helps with slow third-party content like badges and ads Download scripts in parallel but the cons are: Costly even if blank Blocks page onload I want to use an iframe to load ads using the technique mentioned on this site: http://meanderingpassage.com/2007/08/15/keeping-javascript-widgets-from-controlling-your-blog/ Does using this technique mean that as soon as the html contents requested by the iframe are returned to the client, it will load the ad script, potentially blocking the rest of the page's rendering and downloading? Or will the iframe request get processed concurrently while rest of the document is downloaded and rendered?

• How can I convert arbitrary strings to CLS-Compliant names?

  - by Brian Hinchey

  Does anyone know of an algorithm (or external library) that I could call to convert an arbitrary string (i.e. outside my control) to be CLS compliant? I am generating a dynamic RDLC (Client Report Definition) for an ASP.Net Report Viewer control and some of the field names need to be based on strings entered by the user. Unfortunately I have little control over the entry of the field names by the client (through a 3rd party CMS). But I am quite flexible around substitutions required to create the compliant string. I have a reactive hack algorithm for now along the lines of: public static string FormatForDynamicRdlc(this string s) { //We need to change this string to be CLS compliant. return s.Replace(Environment.NewLine, string.Empty) .Replace("\t", string.Empty) .Replace(",", string.Empty) .Replace("-", "_") .Replace(" ", "_"); } But I would love something more comprehensive. Any ideas? NOTE: If it is of any help, the algorithm I am using to create the dynamic RDLC is based on the BuildRDLC method found here: http://csharpshooter.blogspot.com/2007/08/revised-dynamic-rdlc-generation.html

• PHP Download Script

  - by KA_lin

  [edited] I am trying to make a script that downloads a file, the problem is that i am accesing a page(from a server on the network) that generates that file (opens a download window). Is there a way I can get that file witought that pop-up in php? NOTE: I cannot modify the generating page... It is an excel file. The application is called Cognos. I managed with opera to see page variables parsed so I can get to the download page but I must make that download in a folder without the download pop-up

• Determine if a specific activity in an application can be launched...

  - by Justin

  Applications can have any number of launchable activities. I know how to get the list of these activities via PackageManager. Is there a way to determine which activities can be launched via startActivity? For example, the Documents To Go app has different activities that will start Word, Excel, Powerpoint, PDF, etc... I am able to launch all o these just fine. However, it also contains some activities that I am not able to launch with startActivity... If I attempt to do this I get a SecurityException. I want to be able to determine which activities I can safely launch and which I cannot so I only present the user with a list of activities that I can safely launch from within my application... Is this possible?

• How to do simple math in datagridview

  - by EB

  I am new to C#. I have a datagridview with 9 columns. I am simply trying take the value in column 5 and subtract it from column 6. Then display the result in column 9. It seems simple enough.I know it's done in excel all the time. But I just cannot figure this out. Do I need to create a new class with a method called calculate columns? or does the datagridview class have something already built in that can handle this? Again, I am new to C#. Any help would be appreciated. Thank you, Oceantrain.

• Are there C# controls that can be used to create a hierarchical list of prioritised items?

  - by Mendokusai

  I need to be able to display and edit a hierarchical list of tasks in a C# app. It can either be a Windows form app, or ASP.NET. Basically, I want similar behaviour to the way Microsoft Project handles tasks. The control would need to: 1) Maintain a list of items made up of several fields 2) Each item can have a number of children (at least 3 levels of nesting) 3) It needs to be very easy to change the parents/children of an item 4) It needs to be very easy to edit the fields (as fast as changing cells in Excel) 5) It needs to be very easy to reorder the items by dragging and dropping or cut and paste 6) If I can easily connect the control to a database, even better Before I go and create something manually, I'm wondering if there is something available already?

  - by Helpme

  Hi! I'm purposely targeting Java OS 1.4.2 I'm trying to use an iterator combined with apache's POI to read an excel spreadsheet. The code runs perfectly in java 1.5, but in the 1.4.2 version I get the error listed in the question subject. the code is: Iterator myIter = null; it breaks on that line of code, which is clearly at the beginning of the application. I dont understand what needs to be done to correct this issue. Please let me know if you have any insight!

• Condensing multiple else if statements, referencing them from a table?

  - by Haskella

  Hi I'm about to type some 500 else if statements into my code (PHP) which have the exact same coding each: if (color=White); rgb = 255-255-255; print rgb; else if (color=Black); rgb = 0-0-0; print rgb; else if (color=Red); rgb = 255-0-0; print rgb; else if (color=Blue); rgb = 0-0-255; print rgb; [the list keeps going] I also (luckily) have a table that displays the color in the first column and rgb value in the next column for 500 of them... how do I use this to save time typing all those else if statements? Some how I have to reference the table file (made in excel, I'm guessing I'll have to save it as .csv?)

• Lines-of-code counting for many C# solutions

  - by Eric

  I am currently researching a solution for counting lines of code in C#. I pretty much need a combination of the following two tools: http://richnewman.wordpress.com/2007/07/01/c-and-vbnet-line-count-utility/ http://www.locmetrics.com/index.html My problem is that I need to recursively scan a folder containing a lot of visual studio solutions. So can't really use the first tool without any major work on its code, as it's only able to scan a single solution at a time. But I also need to split the results for each solution, preferably even the contained projects. This disqualifies the second tool I found. I also found NDepend which suffers from the same problem. Do you know of any free tools that do what I need? I am unable to find anything suitable.

• How do I diff two spreadsheets?

  - by neu242

  We have a lot of spreadsheets (xls) in our subversion repository. These are usually edited with gnumeric or openoffice.org, and are mostly used to populate databases for unit testing with dbUnit. There are no easy ways of doing diffs on xls files that I know of, and this makes merging extremely tedious and error prone. I've found Spreadsheet Compare, but it requires Excel 2000 or later. I've also tried to convert the spreadsheets to xml and doing a regular diff, but it really feels as a last resort. Are there any tools for diffing two spreadsheets (xls or ods)? I am primarily looking for a multi-platform/open source tool.

• Export view data programmatically in Access/SQL Server

  - by andy

  We have an Access application front-end connected to a SQL Server 2000 database. We would like to be able to programmatically export the results of some views to whatever format we can (ideally Excel, but CSV / tab delimited is fine). Up until now we've just hit F11, opened up the view, and hit File-Save As, but we're starting to get results with more than 16,000 results, which can't be exported. I'd like some sort of server side stored procedure we can trigger that will do this. I'm aware of the sp_makewebtask procedure that does this, however it requires administrative rights on the server, and for obvious reasons we can't give that to everyone. Any ideas?
