  • creating a file from input stream

    - by daemonkid
    My component will receive a pdf file as a filestream from which I will need to create a file. For testing purposes I am trying to read a file using the filestream object and recreate it at a different location. But the recreated file is created blank. the recreated file has the same number of pages though... This is the code StreamReader sr = new StreamReader(_filePath); str = sr.ReadToEnd(); File.WriteAllText(@"C:\recreated.pdf", str); what am I doing wrong?

  • Vim: yank and replace -- the same yanked input -- multiple times, and two other questions

    - by Hassan Syed
    Now that I am using vim for everything I type, rather then just for configuring servers, I wan't to sort out the following trivialities. I tried to formulate Google search queries but the results didn't address my questions :D. Question one: How do I yank and replace multiple times ? Once I have something in the yank history (if that is what its called) and then highlight and use the 'p' char in command mode the replaced text is put at the front of the yank history; therefore subsequent replace operations do not use the the text I intended. I imagine this to be a usefull feature under certain circumstances but I do not have a need for it in my workflow. Question two: How do I type text without causing the line to ripple forward ? I use hard-tab stops to allign my code in a certain way -- e.g., FunctionNameX ( lala * land ); FunctionNameProto ( ); When I figure out what needs to go into the second function, how do I insert it without move the text up ? Question three Is there a way of having a uniform yank history across gvim instances on the same machine ? I have 1 monitors. Just wondering, atm I am using highlight + mouse middle click.

  • Powershell function that creates a array by input

    - by user2971548
    I'm quite new to Powershell and working on a little project with functions. What I'm trying to do is creating a function that takes 2 arguments. The first argument ($Item1) decides the size of the array, the second argument ($Item2) decides the value of the indexes. So if I write: $addToArray 10 5 I need the function to create a array with 10 indexes and the value 5 in each of them. The second argument would also have to take "text" as a value. This is my code so far. $testArray = @(); $indexSize = 0; function addToArray($Item1, $Item2) { while ($indexSize -ne $Item1) { $indexSize ++; } Write-host "###"; while ($Item2 -ne $indexSize) { $script:testArray += $Item2; $Item2 ++; } } Any help is appreciated. Kind regards Dennis Berntsson

  • c++ File input/output

    - by Myx
    Hi: I am trying to read from a file using fgets and sscanf. In my file, I have characters on each line of the while which I wish to put into a vector. So far, I have the following: FILE *fp; fp = fopen(filename, "r"); if(!fp) { fprintf(stderr, "Unable to open file %s\n", filename); return 0; } // Read file int line_count = 0; char buffer[1024]; while(fgets(buffer, 1023, fp)) { // Increment line counter line_count++; char *bufferp = buffer; ... while(*bufferp != '\n') { char *tmp; if(sscanf(bufferp, "%c", tmp) != 1) { fprintf(stderr, "Syntax error reading axiom on " "line %d in file %s\n", line_count, filename); return 0; } axiom.push_back(tmp); printf("put %s in axiom vector\n", axiom[axiom.size()-1]); // increment buffer pointer bufferp++; } } my axiom vector is defined as vector<char *> axiom;. When I run my program, I get a seg fault. It happens when I do the sscanf. Any suggestions on what I'm doing wrong?

  • How to roll back changes in gridview in case of incorrect input

    - by Mustafa A. Jabbar
    Hi, I have a DataGridView that is bound to a list of object. It has some columns that the user can edit. There are certain inputs that are not allowed for a row as a whole. How can I roll back if the user enters invalid inputs in some cell. I tried using the RowValidating event handler but it was not called after cell value has been changed. Even when I implemet CellValueChanged, I still cannot roll back the changes. Any idea how to accomplish this

  • Nokogiri Truncating XML Input

    - by bdorry
    I am having issues with a colleagues machine truncating XML while using Nokogiri to parse a Media RSS feed. The feed is a standard Media RSS feed, and the XML is not malformed. It looks like it simply stops at a certain point in the XML and closes any tags that would have been open at that current point in the document. (Unfortunately I do not have the XML avialable to me right now, but I will update this question with the actual XML when I have it available to me). My confusion comes from it working fine on my machine (OSX 10.6, Nokogiri 1.4.4) while it in correctly on his machine using the same setup - however his machine is a few years older. I imagine that there is a difference somewhere but unfortunately I don't know what to look for. Any thoughts or direction would be greatly appreciated.

  • Rails: form input type and getting the filename

    - by Shyam
    Hi, As I am using Ruby on Rails to build an application, which only runs locally, I am lost in the woods (a nuby without a compass). I have a simple MVC application and my view is missing one thing I could really use. I want to select a local file just to retrieve it's filename. I know it's relatively easy to use the form tag helpers for uploading: <%= file_field 'upload', 'datafile' %></p> I wonder how I could get the filename from the selected file, without uploading the file.

  • Can someone tell me why this JavaScript code isn't lining up an array in order?

    - by DarkLightA
    Live code: http://jsfiddle.net/fCUZC/ //INPUT ARRAY: var input = [28,32,21,11,8,2,14,32,64]; //VARIABLE DECLARATION. a = highest number so far, b = position of that number entireLoop: for (var i = 1; i<=input.length; i++) { if(input[i] > input[i-1]) { for(var o = i; o>=0; o--) { if(input[i-1] > input[o]) { input.splice(i,0,input[o]); input.splice((o+1),1); continue entireLoop; } else if(input[o] > input[0]) { input.splice(0,0,input[o]); input.splice((o+1),1); continue entireLoop; } } } } document.write(input); I'm trying to order the array from largest to smallest, but there's a 32 stuck somewhere. I know there's the sort method, but I'm a newbie and want to try this for myself.

  • Functional programming approach for Java's input/output streams

    - by Elazar Leibovich
    I'm using Java's DataInputStream with scala to parse some simple binary file (which is very bad exprerience due to the lack of unsigned types, even in scala, but that's a different story). However I find myself forced to use mutable data structure, since Java's streams are inherently state preserving entities. What's a good design to wrap Java's streams with nice functional data structure?

  • Java function changing input

    - by Doodle
    I would like to go from one number to another. For example if I started at 6 and my goal was 10 I want a function that on every pass would bring me from 6 towards 10 or if I had the number 14 and my goal was 9 it would count down from 14 towards 9.So far I have (this is written in Processing a Java Api but there is essentially no difference from regualr Java, draw is just a continuous loop) int x=100; void draw(){ x=towards(x,10); println(x); } int towards(int current ,int target){ if(current!=target){ if (current <target){ current=current+1; } else { current=current-1; } } return current; } this gives me the results I would like but I would like to have everything in side of the towards() function. When I replace X with a variable it of course resets it self to the static variable. To sum it up how can I pass a variable to a function and have that variable thats been passed change on every subsequent pass. I have looked into recursion as a solution but that of just brings me to a final solution. I can pass the count to an array but wouldn't like to do that either.

  • ASP.NET MVC 2 user input to SQL 2008 Database problems

    - by Rob
    After my publish in VS2010 the entire website loads and pulls data from the database perfectly. I can even create new users through the site with the correct key code, given out to who needs access. I have two connection strings in my web.config file The first: <add xdt:Transform="SetAttributes" xdt:Locator="Match(name)" name="EveModelContainer" connectionString="metadata=res://*/Models.EdmModel.EveModel.csdl|res://*/Models.EdmModel.EveModel.ssdl|res://*/Models.EdmModel.EveModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=localhost;Initial Catalog=fleet;Persist Security Info=True;User ID=fleet;Password=****&quot;" providerName="System.Data.EntityClient" /> The second: <add xdt:Transform="SetAttributes" xdt:Locator="Match(name)" name="ApplicationServices" connectionString="Data Source=localhost;Initial Catalog=fleet;Persist Security Info=True;User ID=fleet;Password=****;MultipleActiveResultSets=True" /> The first one is the one that is needed to post data with the main application, EveModelContainer. Everything else is pulled using the standard ApplicationServices connection. Do you see anything wrong with my connectionstring? I'm at a complete loss here. The site works perfectly on my friends server and not on mine... Could it be a provider issue? And if I go to iis 7's manager console, and click .net users I get a pop up message saying the custom provider isn't a trusted provider do I want to allow it to run at a higher trust level. I'm at the point where I think its either my string or this trusted provider error... but I have no clue how to add to the trusted provider list... Thank you in advance!!!

  • Mock a void method which change the input value

    - by Kar
    Hi, How could I mock a void method with parameters and change the value parameters? My void method looks like this: public interface IFoo { void GetValue(int x, object y) // takes x and do something then access another class to get the value of y } I prepared a delegate class: private delegate void GetValueDelegate(int x, object y); private void GetValue(int x, object y) { // process x // prepare a new object obj if (y == null) y = new Object(); if (//some checks) y = obj; } I wrote something like this: Expect.Call(delegate {x.GetValue(5, null);}).Do (new GetValueDelegate(GetValue)).IgnoreArguments().Repeat.Any(); But seems like it's not working. Any clue on what could be wrong?

  • Binding KeyUp event to Input Field

    - by user306686
    I am dynamically generating textboxes in ruby using <%0.upto(4) do |i| % <%= text_field_tag('relative_factor[]', @prefill_values[:relative_factor][i],:size = 6,:maxlength = 5) % <%end% it generates following HTML markup Another set of textboxes: <%0.upto(4) do |i| % <%= text_field_tag('rating_factor[]', @prefill_values[:relative_factor][i],:size = 6,:maxlength = 5) % <%end% it generates following HTML markup I have one more textbox: ..... I want to update id="rating_factor_" textboxes as the value in either id="multiple" textbox changes or id="relative_factor_" textboxes changes. E.g. id="multiple" textbox = 5 id="relative_factor_" value= 0.0 textbox = 1 id="relative_factor_" value= 1.0 textbox = 2 id="relative_factor_" value= 2.0 textbox = 3 id="relative_factor_" value= 3.0 textbox = 4 id="relative_factor_" value= 4.0 textbox = 5 I want to show (multiple multiple and relative_factor_ and show) id="rating_factor_" value= 0.0 textbox = 5 id="rating_factor_" value= 1.0 textbox = 10 id="rating_factor_" value= 2.0 textbox = 15 id="rating_factor_" value= 3.0 textbox = 20 id="rating_factor_" value= 4.0 textbox = 25 Now if user changes, id="relative_factor_" value= 1.0 textbox as 1.5 then id="rating_factor_" value= 1.0 textbox should be updated as 7.5 To achieve above goal, I tried binding #relative_factor_ to keyup event but as id is same for all i.e.#relative_factor_, it returns value for first textbox i.e. id="relative_factor_" value= 0.0. Please guide me to crack this problem. Thanks in Advance.
