  • How to create a web framework in C# without ASP?

    - by Mark
    I've managed to get a C# asp page running under ubuntu/apache/mono, but I don't want to write my framework in these ASP pages, I want to use straight C# and then I'll use a templating language for my views. But I don't know where to begin? C# is a compiled language, so... how would I do this? Would I compile everything and then have apache hook into the (single) executable and pass in the the request URL? Could I request specific .cs pages and then have apache tell it to compile and then "display" it only if it's been updated? Can the "view" files be compiled individually to avoid having to recompile everything every time there's a change? Is there some "base" I can work from, or am I going to have to reinvent accessing GET and POST variables (by reading header info) and all sorts of other stuff we take for granted in languages like PHP?

  • How to write a regular expression for "everything between X and Y" for use with preg_replace

    - by pg
    I want to take a variable called $encoded_str and and remove cd1, CD1 and anything between the first 'l' and the last blank space. So for example "lp6 id4 STRINGcd1" would return "STRING". I'm using PHP 4 for now so I can't use str_ireplace, I have this: $encoded_str=str_replace('CD1','',$encoded_str); $encoded_str=str_replace('cd1','',$encoded_str); $encoded_str=preg_replace('X','',$encoded_str); I've RTFM for preg_replace but am a bit confused. What should I replace the X with and can you suggest a decent introductory primer for writing regular expressions?

  • C#: Using regular expression (Regex) to duplicate a specific character in a string

    - by user3703944
    Anyone know how to use regex to duplicate a specific character in a string? I have a path that is entered like this: C:/Example/example I would like to use regex (or any other method) to display it like this: C://Example//example Is it possible? This is where I'm getting the file path private void btnSearchImage_Click_1(object sender, EventArgs e) { OpenFileDialog ofd = new OpenFileDialog(); ofd.Filter = "Image Files(*.jpg; *.jpeg; *.gif; *.bmp)|*.jpg; *.jpeg; *.gif; *.bmp"; if (ofd.ShowDialog() == System.Windows.Forms.DialogResult.OK) { string filenName = ofd.FileName; pictureBox1.Image = new Bitmap(filenName); string path = filenName; txtimgPath.Text = path; } } Thanks

  • Expression parser library for Android.

    - by Malx
    What is the best way to evaluate simple conditional statements like: "a>b" ? "x-4<10+y & y>x" ? Expressions are loaded from external file. Variables are set in application. Syntax used is not essential. It may be "&" or "and" or any other supported with language/library. I need to take different action depending on result of evaluation - is it true or false. Could I use any parser already included with Andorid? Is there some way to use JS "eval" from browser component? Is it possible to use sqlite expressions to get true/false result without selecting anything? Those libraries are implemented in native code. Will it be faster and less battery expensive?

  • Turning logical expression around

    - by BluePrint
    I have the following code: bool s = true; for (...; ...; ...) { // code that defines A, B, C, D // and w, x, y, z if (!(A < w) && s == true) { s = false; } if (!(B < x) && s == true) { s = false; } if (!(C < y) && s == true) { s = false; } if (!(D < z) && s == true) { s = false; } } This code is working well. However, I want to, for several (unimportant) reasons, change the code so that I can initiate s = false; and set it to true inside the if-statement. It tried the following: bool s = false; for (...; ...; ...) { // code that defines A, B, C, D // and w, x, y, z if (A >= w && s == false) { s = true; } if (B >= x && s == false) { s = true; } if (C >= y && s == false) { s = true; } if (D >= z && s == false) { s = true; } } However, this is not working properly as the code above is working. I know thought wrong somewhere in the logic, but I can't figure out where. Does anbyone see my probably obvious error? EDIT: Added three more if-statemets. Missed them since they were commented away.

  • regular expression for validation not working

    - by Camran
    I have a "description textarea" inside a form where user may enter a description for an item. This is validated with javascript before the form beeing submitted. One of the validation-steps is this: else if (!fld.value.match(desExp)){ And desExp: var desExp = /^\s*(\w[^\w]*){3}.*$/gm; Now my problem, this works fine on all cases except for descriptions where the description BEGINS with a special character of the swedish language (å, ä, ö). This wont work: åäö hello world But this will: hello world åäö Any fixes? Thanks

  • Regex if-else expression

    - by craig
    I'm trying to extract the # of minutes from a text field using Oracle's REGEXP_SUBSTR() function. Data: Treatment of PC7, PT1 on left. 15 min. 15 minutes. 15 minutes 15 mins. 15 mins 15 min. 15 min 15min 15 In each case, I'm hoping to extract the '15' part of the string. Attempts: \d+ gets all of the numeric values, including the '7' and '1', which is undesirable. (\d)+(?=\ ?min) get the '15' from all rows except the last. (?((\d)+(?=\ ?min))((\d)+(?=\ ?min))|\d+), an if-else statement, doesnt' match anything. What is wrong with my if-else statement?

  • Best way to convert log files (*.txt) to web-friendly files (*.html, *.jsp, etc)?

    - by prometheus
    I have a bunch of log files which are pure text. Here is an example of one... Overall Failures Log SW Failures - 03.09.2010 - /logs/swfailures.txt - 23 errors - 24 warnings HW Failures - 03.09.2010 - /logs/hwfailures.txt - 42 errors - 25 warnings SW Failures - 03.10.2010 - /logs/swfailures.txt - 32 errors - 27 warnings HW Failures - 03.10.2010 - /logs/hwfailures.txt - 11 errors - 31 warnings These files can get quite large and contain a lot of other information. I'd like to produce an HTML file from this log that will add links to key portions and allow the user to open up other log files as a result... SW Failures - 03.09.2010 - <a href="/logs/swfailures.txt">/logs/swfailures.txt</a> - 23 errors - 24 warnings This is greatly simplified as I would like to add many more links and other html elements. My question is -- what is the best way to do this? If the files are large, should I generate the html before serving it to the user or will jsp do? Should I use perl or other scripting languages to do this? What are your thoughts and experiences?

  • Regular Expression Program

    - by david robers
    Hi I have the following text: SMWABCCA ABCCAEZZRHM NABCCAYJG XABCCA ABCCADK ABCCASKIYRH ABCCAKY PQABCCAK ABCCAKQ This method takes a regex in out by the user and SHOULD print out the Strings it applies to but seems to print out something completely different: private void matchIt(String regex) { Pattern p = Pattern.compile(regex); Matcher m = null; boolean found = false; for(int i = 0; i < data.length; i++){ m = p.matcher(data[i]); if(m.find()){ out.println(data[i]); found = true; } } if(!found){ out.println("Pattern Not Found"); } } When inputting "[C]" It outputs: SMWABCCA ABCCAEZZRHM NABCCAYJG XABCCA ABCCADK ABCCASKIYRH ABCCAKY PQABCCAK ABCCAKQ Any ideas why? I think I'm using m.find() improperly...

  • regular expression for bit strings with even number of 1s

    - by equilibrium
    Let L= { w in (0+1)* | w has even number of 1s}, i.e. L is the set of all bit strings with even number of 1s. Which one of the regular expressions below represents L? A) (0*10*1)* B) 0*(10*10*)* C) 0*(10*1)* 0* D) 0*1(10*1)* 10* According to me option D is never correct because it does not represent the bit string with zero 1s. But what about the other options? We are concerned about the number of 1s(even or not) not the number of zeros doesn't matter. Then which is the correct option and why?

  • Simple Search and Replace use of Regular Expression

    - by nunos
    So, I am adapting some code I found online to suit my needs. However, my set_pixel function has two more parameters. Since there are lots of calls to this function even doing a quick paste over would be very tedious. So, I thought this would be a good time for me to learn some simple regular expressions. So, I have calls of this type: set_pixel(arg1, arg2); which I want to change to something like: set_pixel(arg1, arg2, arg3, arg4); Note: arg1 and and 2 should be preserved, whereas arg3 and arg4 are most of the time the same. How can I achieve this?
