how to implement word count bash shell

- by codemax

hey guys. I am trying to write my own code for the word count in bash shell. I did usual way. But i wanna use pipe's output to count the word. So for eg the 1st command is cat and i am redirecting to a file called med. Now i have to use to 'dup2' function to count the words in that file. How can i write the code for my wc? This is the code for my shell pgm : void process( char* cmd[], int arg_count ) { pid_t pid; pid = fork(); char path[81]; getcwd(path,81); strcat(path,"/"); strcat(path,cmd[0]); if(pid < 0) { cout << "Fork Failed" << endl; exit(-1); } else if( pid == 0 ) { int fd; fd =open("med", O_RDONLY); dup2(fd ,0); execvp( path, cmd ); } else { wait(NULL); } } And my wordcount is : int main(int argc, char *argv[]) { char ch; int count = 0; ifstream infile(argv[1]); while(!infile.eof()) { infile.get(ch); if(ch == ' ') { count++; } } return 0; } I dont know how to do input redirection i want my code to do this : When i just type wordcount in my shell implementation, I want it to count the words in the med file by default. Thanks in advance

How can I embed images in an ASP.NET Generated Word File

- by Nikos Steiakakis

Hi everyone! I have a quite common problem, as I saw in the various user groups but could not find a suitable answer. What I want to do is generate an ASP.NET page in my website which will have the option of being exported into Microsoft Word .doc format. The method I have used is this: Response.Clear(); Response.AddHeader("content-disposition", "attachment;filename=Test.doc"); Response.Charset = ""; Response.Cache.SetCacheability(HttpCacheability.NoCache); Response.ContentType = "application/msword"; StringWriter sw = new StringWriter(); HtmlTextWriter htmlWrite = new HtmlTextWriter(sw); Page.RenderControl(htmlWrite); Response.Write(sw.ToString()); Response.End(); However this eventhough it generates a word doc, the images are note embedded in the document, rather they are placed as links. I have looked for a way to do this, but have not found something that actually worked. I would appreciate any help I can get, since this as "last minute" requirement (talk about typical) Thanks

Word-wrap grid cells in Ext JS

- by richardtallent

(This is not a question per se, I'm documenting a solution I found using Ext JS 3.1.0. But, feel free to answer if you know of a better solution!) The Column config for an Ext JS Grid object does not have a native way to allow word-wrapped text, but there is a css property to override the inline CSS of the TD elements created by the grid. Unfortunately, the TD elements contain a DIV element wrapping the content, and that DIV is set to white-space:nowrap by Ext JS's stylesheet, so overriding the TD CSS does no good. I added the following to my main CSS file, a simple fix that appears to not break any grid functionality, but allows any white-space setting I apply to the TD to pass through to the DIV. .x-grid3-cell { /* TD is defaulted to word-wrap. Turn it off so it can be turned on for specific columns. */ white-space:nowrap; } .x-grid3-cell-inner { /* Inherit DIV's white-space from TD parent, since DIV's inline style is not accessible in the column definition. */ white-space:inherit; } YMMV, but it works for me, wanted to get it out there as a solution since I couldn't find a working solution by searching the Interwebs.

Regular expressions - finding and comparing the first instance of a word

- by Dan

Hi there, I am currently trying to write a regular expression to pull links out of a page I have. The problem is the links need to be pulled out only if the links have 'stock' for example. This is an outline of what I have code wise: <td class="prd-details"> <a href="somepage"> ... <span class="collect unavailable"> </td> <td class="prd-details"> <a href="somepage"> ... <span class="collect available"> </td> What I would like to do is pull out the links only if 'collect available' is in the tag. I have tried to do this with the regular expression: (?s)prd-details[^=]+="([^"]+)" .+?collect{1}[^\s]+ available However on running it, it will find the first 'prd-details' class and keep going until it finds 'collect available', thereby taking the incorrect results. I thought by specifying the {1} after the word collect it would only use the first instance of the word it finds, but apparently I'm wrong. I've been trying to use different things such as positive and negative lookaheads but I cant seem to get anything to work. Might anyone be able to help me with this issue? Thanks, Dan

Extracting a number from a 1-word string

- by Kyle

In this program I am trying to make, I have an expression (such as "I=23mm", or "H=4V") and I am trying to extract the 23 (or the 4) out of it, so that I can turn it into an integer. The problem I keep running into is that since the expression I am trying to take the numbers out of is 1 word, I cannot use split() or anything. One example I saw but wouldnt work was - I="I=2.7A" [int(s) for s in I.split() if s.isdigit()] This wouldnt work because it only takes the numbers are are delimited by spaces. If there was a number in the word int078vert, it wouldnt extract it. Also, mine doesnt have spaces to delimit. I tried one that looked like this, re.findall("\d+.\d+", "Amps= 1.4 I") but it didnt work either, because the number that is being passed is not always 2 digits. It could be something like 5, or something like 13.6. What code do I need to write so that if I pass a string, such as I="I=2.4A" or I="A=3V" So that I can extract only the number out of this string? (and do operations on it)? There are no spaces or other constant chars that I can delimit by.

JQuery remove() not working with a two word id

- by Programer

I have a button <button onclick="takedown()"> take down </button> that creates a H1 and button with the id of the text in my text field and h1 at the end for the h1 and button at the end for the button the button has a onclick onclick="delete()". This is that function function takedown(){ note = document.getElementById("noteinput").value; idh1 = note + "h1"; idbutton = note + "button"; idcenter = note + "center"; $('<center id="' + idcenter + '"> <h1 id="' + idh1 + '">' + note + '</h1> <button id="'+ idbutton +'" onclick="deletenote()"> Delete </button> </center>').appendTo("body"); } For the delete function the remove() works only if the id of the button and the h1 is one word. function deletenote(){ // First setting var idbuttondelete = event.target.id; var idh1delete = idbuttondelete.replace("button", "h1"); // Removing the button, h1,center $('#' + idbuttondelete).remove(); $('#' + idh1delete).remove(); } Does anybody know whats wrong or how to use JQuery to delete something if it has a two word id.

Display HTML page in Office 2003 or 2007 task pane via VBA

- by Malcolm

Is it possible to display an HTML page in an Office 2003 and/or 2007 task pane via VBA? Background: We have a complicated configuration file that our users maintain in Word (using a real editor is not an option for our audience). We would like to create several toolbar buttons that display a basic HTML page in a task pane as a form of online help for our users. The reason we want to use a task pane to display help (vs. an external browser or traditional help engine) is so that the help content is "embedded" in Word vs. displayed via a seperate application. The problem with using a regular browser or help engine to display help is that users have to manually size and position both applications so that they can see them simultaneously and its very easy to "lose" one application when togging between many applications. We don't want to go down the route of writing a VisualStudio based task pane component - we want to keep things simple (KISS) and encapsulate everything in an easy to distribute Word template file (.dot or dotx.). Suggestions?

How to parse out MS Word formatting?

- by chobo2

I have a rich html textbox on my asp.net mvc application. The rich html textbox is some jquery plugin that I use and has basic stuff like bold,underline and etc. Now I am anticipating that people will maybe write something in word and then copy and paste it into my textbox. However I limit the number of characters a person can have. This is a test to show how much formatting gets made. • One • Two • Three So I wrote that above(it does not copy to well into here). Basically it is a line of text and "how" is bold and the "one,two,three" are a bullet list. Word says it is 70 characters long with spacing. However when I post this data from my textbox to my server I get a length back of 24577 characters. so I checked what was being sent and I get this <meta http-equiv="Content-Type" content="text/html; charset=utf-8"><meta name="ProgId" content="Word.Document"><meta name="Generator" content="Microsoft Word 12"><meta name="Originator" content="Microsoft Word 12"><link rel="File-List" href="file:///C:%5CUsers%5Cchobo2%5CAppData%5CLocal%5CTemp%5Cmsohtmlclip1%5C01%5Cclip_filelist.xml"><link rel="themeData" href="file:///C:%5CUsers%5Cchobo2%5CAppData%5CLocal%5CTemp%5Cmsohtmlclip1%5C01%5Cclip_themedata.thmx"><link rel="colorSchemeMapping" href="file:///C:%5CUsers%5Cchobo2%5CAppData%5CLocal%5CTemp%5Cmsohtmlclip1%5C01%5Cclip_colorschememapping.xml"><style>  </style> <p class="MsoNormal">This is a test to show <b style="">how</b> much formatting gets made.</p> <p class="MsoListParagraphCxSpFirst" style="text-indent: -0.25in;"><span style="font-family: Symbol;"><span style="">·<span style="font: 7pt "Times New Roman";">         </span></span></span>One</p> <p class="MsoListParagraphCxSpMiddle" style="text-indent: -0.25in;"><span style="font-family: Symbol;"><span style="">·<span style="font: 7pt "Times New Roman";">         </span></span></span>Two</p> <p class="MsoListParagraphCxSpMiddle" style="text-indent: -0.25in;"><span style="font-family: Symbol;"><span style="">·<span style="font: 7pt "Times New Roman";">         </span></span></span>Three</p> <p class="MsoListParagraphCxSpLast"><o:p> </o:p></p> Is there something I can use to get rid of all this stuff?

Avoid Powerpoint(/Word) 2010 creating temporary files in working directory

- by Ben

When opening a temporary file, Powerpoint 2010 usually creates a temporary, hidden file called ~$filename.pptx in the same directory. This is undesirable, since it can cause unnecessary activity with e.g. Dropbox. Furthermore, the "Documents" folder should not be used for temporary files -- we have the %TEMP% folder for that. So, is it possible to have Powerpoint create its temporary files in %TEMP% instead? The following link suggests that it might not be possible: http://support.microsoft.com/kb/211632 Also, why does Microsoft not use the %TEMP% folder?

Configure IE to use MS Word Viewer as .doc viewer on Citrix server with Office installed

- by Adam Towne

We have a small number of citrix servers that all have office installed. Only a small subset of users have access to office. Everyone is set to open office documents with the free viewers on the Citrix servers. We control access to office through NTFS permissions. We now have a large number of users who need to be able to view office documents from a webpage. Opening office files normally works fine. When users open the office documents from the link in a webpage, it ignores the file associations and attempts to open the document with the full office program. How can I change the program that IE uses to open office documents, or how can I force it to use the file associations I set in the operating system?

Aligning Numbered Bullet Points in Word 2007

- by Frustratedwithbullets

Hello, I am putting together a very large business manual which incorportaes numbered heading, steps to follow, diagrams, etc. When using the bullet points, they align perfectly as I work through the processes. However when I include a diagram, or something different from the "norm" of text, the alignment changes. I would like all the bullets points to be aligned in the whole document regardless of where they appear in the document. Is there a way to save the settings so that the bullets always appear in the same position? Currently I am having to reset the indents by dragging the tabs on the ruler. This will be a large document, so I don't want to manually adjust the numbered bullets every time. Help would be greatly appreciated. Thanks very much.

Disappearing mouse cursor in Word, Notepad, Outlook

- by user161548

I purchased a lenovo led monitor as a second monitor so I have dual screens now. Everything works great except all text programs make my cursor disappear on the new monitor. Everything works great on the old monitor but if I drag a text document to the new screen the cursor is invisible. Any ideas on what to try? Odd to me that it works on one and not the other so assuming it has something to do with the monitor but none of the settings seem to make a difference.

Office 2010 Trusted Locations not working after restart

- by Josh King

In Excel 2010, on Windows XP, I am unable to open files - through the open dialog box - from a network drive. The sever has already been added to the Trusted Locations and now most security settings turned down or off. Excel will show "Downloading ..." on that status bar and a progress bar which doesn't progress. We have left Excel sitting in this state for 30+ minutes and no change. A similar problem occurs when saving files to network shares. If we use explorer to navigate to the files and double click them they open flawlessly. No add-ins are active. We also have this problem in Word 2010, but the server was not initially in the Trusted Locations. I added it and it worked until the PC was reset, it now exhibits the same issues as Excel where the server is in the Trusted locations but will not open files. I have tried removing the server from the Trusted Location in both applications, restarting the PC and re-adding them (testing before, after and in-between) and had no luck.

QR Codes Printing, but Not Printing Correctly - Any Ideas?

- by SDS

I am mail merging some QR codes via file paths stored in Excel into a label template in MS Word 2013. I have the whole process with the Ctrl+F9 working properly, but I am stumped on this: On the 30 label sheet I am trying to print I have 6 labels that are repeating information, and stored in duplicated rows in Excel for this print job. All of the labels have 2 images on them, one is a logo and the other one is a unique QR code for that person. For the first set of 6 labels that print out, everything works perfect. However, from the 2nd time the information is printed onward all of the merged fields and logo look correct, but the QR codes are printing strangely. Basically it's the QR code as I want it, but with a copy of itself covering the top left 25% of the QR code. Print preview doesn't show this happening, only once it's printed does it come out like this. I've been trying everything I can think of to fix this and don't know what to do. So far I've: Recreated the document several times, tried duplicating the images in the source folder and giving the links in the Excel document new file paths in case the mail merge feeding from the same .jpg was an issue (even though it's not a problem with the logo) Any help or insight is greatly appreciate because this is a test run for a larger batch run that I need to get done soon :( Thank you!

What algorithm(s) can be used to achieve reasonably good next word prediction?

- by yati sagade

What is a good way of implementing "next-word prediction"? For example, the user types "I am" and the system suggests "a" and "not" (or possibly others) as the next word. I am aware of a method that uses Markov Chains and some training text(obviously) to more or less achieve this. But I read somewhere that this method is very restrictive and applies to very simple cases. I understand basics of neural networks and genetic algorithms(though have never used them in a serious project) and maybe they could be of some help. I wonder if there are any algorithms that, given appropriate training text(e.g., newspaper articles, and the user's own typing) can come up with reasonably appropriate suggestions for the next word. If not (links to)algorithms, general high-level methods to attack this problem are welcome.
