  • Problems updating a textBox ASP.NET

    - by Roger Filipe
    Hello, I'm starting in asp.net and am having some problems that I do not understand. The problem is this, I am building a site for news. Every news has a title and body. I have a page where I can insert news, this page uses a textbox for each of the fields (title and body), after clicking the submit button everything goes ok and saves the values in the database. And o have another page where I can read the news, I use labels for each of the camps, these labels are defined in the Page_Load. Now I'm having problems on the page where I can edit the news. I am loading two textboxes (title and body) in the Page_Load, so far so good, but then when I change the text and I click the submit button, it ignores the changes that I made in the text and saves the text loaded in Page_Load. This code doesn't show any database connection but you can understand what i'm talking about. protected void Page_Load(object sender, EventArgs e) { textboxTitle.Text = "This is the title of the news"; textboxBody.Text = "This is the body of the news "; } I load the page, make the changes in the text , and then click submit. protected void btnSubmit_Click(object sender, EventArgs e) { String title = textboxTitle.Text; String body = textboxBody.Text; Response.Write("Title: " + title + " || "); Response.Write("Body: " + body ); } Nothing happens, the text in the textboxes is always the one I loaded in the page_load, how do I update the Text in the textboxes?

  • Why is my simple python gtk+cairo program running so slowly/stutteringly?

    - by synapz
    My program draws circles moving on the window. I think I must be missing some basic gtk/cairo concept because it seems to be running too slowly/stutteringly for what I am doing. Any ideas?

  • Control the size of points in an R scatterplot?

    - by Nick
    In R, the plot() function takes a pch argument that controls the appearance of the points in the plot. I'm making scatterplots with tens of thousands of points and prefer a small, but not too small dot. Basically, I find pch='.' to be too small, but pch=19 to be too fat. Is there something in the middle or some way to scale the dots down somehow?

  • How to map (large) integer on (small in size( alphanumeric string with PHP? (Cantor?)

    - by Glooh
    Dear all, I can't figure out how to optimally do the following in PHP: In a database, I have messages with a unique ID, like 19041985. Now, I want to refer to these messages in a short-url service but not using generated hashes but by simply 'calculate' the original ID. In other words, for example: http://short.url/sYsn7 should let me calculate the message ID the visitor would like to request. To make it more obvious, I wrote the following in PHP to generate these 'alphanumeric ID versions' and of course, the other way around will let me calculate the original message ID. The question is: Is this the optimal way of doing this? I hardly think so, but can't think of anything else. $alphanumString = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ-_'; for($i=0;$i < strlen($alphanumString);$i++) { $alphanumArray[$i] = substr($alphanumString,$i,1); } $id = 19041985; $out = ''; for($i=0;$i < strlen($id);$i++) { if(isset($alphanumString["".substr($id,$i,2).""]) && strlen($alphanumString["".substr($id,$i,2).""]) 0) { $out.=$alphanumString["".substr($id,$i,2).""]; } else { $out.=$alphanumString["".substr($id,$i,1).""]; $out.=$alphanumString["".substr($id,($i+1),1).""]; } $i++; } print $out;

  • Problems with a from CSS

    - by Michael
    I am trying to create a fairly basic form with in my maincontent. I am sure I am coding things incorrectly and it is driving me crazy. Note my code. I get extremely wide vertical spacing in IE 7 and the bacground color between the field sets does not work correctly. All is good in FF. My CSS is: fieldset { margin: 1.5em 0 0 0; padding: 0; border-style: none; border-top: 1px solid #BFBAB0; background-color: #FFFFFF; } legend { margin-left: 1em; color: #000000; font-weight: bold; } fieldset ol { padding: 1em 1em 0 1em; list-style: none; } fieldset li { padding-bottom: 1em; } fieldset.submit { border-style: none; } { var w = document.myform.mylist.selectedIndex; var selected_text = document.myform.mylist.options[w].text; alert(selected_text); } label em { display: block; color: #900; font-size: 85%; font-style: normal; text-transform: uppercase; } This is my html code. <div id="mainContent1"> <form name="myform"> <label for="mylist"><strong>Select an Account Type:</strong></label> <select name="mylist"><option value="traditional">Traditional Account</option> <option value="paperless">Paperless Account</option> </select> </form> <br /><a> </a> <form action="example.php"> <fieldset> <legend>Contact Details</legend> <ol> <li> <label for="name">Name:</label> <input id="name" name="name" class="text" type="text" /> <label for="name"> <em>required</em> </label> </li> <li> <label for="email">Email address:</label> <input id="email" name="email" class="text" type="text" /> <label for="name"> <em>required</em> </li> <li> <label for="phone">Telephone:</label> <input id="phone" name="phone" class="text" type="text" /> <label for="name"> <em>required</em> <ol> <li> <input id="option1" name="option1" class="checkbox" type="checkbox" value="1" /> <label for="option1">Savings</label> </li> <li> <input id="option2" name="option2" class="checkbox" type="checkbox" value="1" /> <label for="option2">Checkings</label> </li> </ol> </fieldset> <fieldset> <legend>Delivery Address</legend> <ol> <li> <label for="address1">Address 1:</label> <input id="address1" name="address1" class="text" type="text" /> </li> <li> <label for="city">City:</label> <input id="city" name="city" class="text" type="text" /> </li> <li> <label for="postcode">Zip Code:</label> <input id="postcode" name="postcode" class="text textSmall" type="text" /> </li> <li> <label for="country">Country:</label> <input id="country" name="country" class="text" type="text" /> </li> </ol> </fieldset> <fieldset class="submit"> <input class="submit" type="submit" value="Submit" /> </fieldset> <fieldset class="clear"> <input class="clear" type="clear" value="Submit" /> </fieldset> </form>

  • C++ casted realloc causing memory leak

    - by wyatt
    I'm using a function I found here to save a webpage to memory with cURL: struct WebpageData { char *pageData; size_t size; }; size_t storePage(void *input, size_t size, size_t nmemb, void *output) { size_t realsize = size * nmemb; struct WebpageData *page = (struct WebpageData *)output; page->pageData = (char *)realloc(page->pageData, page->size + realsize + 1); if(page->pageData) { memcpy(&(page->pageData[page->size]), input, realsize); page->size += realsize; page->pageData[page->size] = 0; } return realsize; } and find the line: page->pageData = (char *)realloc(page->pageData, page->size + realsize + 1); is causing a memory leak of a few hundred bytes per call. The only real change I've made from the original source is casting the line in question to a (char *), which my compiler (gcc, g++ specifically if it's a c/c++ issue, but gcc also wouldn't compile with the uncast statement) insisted upon, but I assume this is the source of the leak. Can anyone elucidate? Thanks

  • Rotate using a transform, then change frame origin, and view expands??

    - by ZaBlanc
    This is quite the iPhone quandry. I am working on a library, but have narrowed down my problem to very simple code. What this code does is create a 50x50 view, applies a rotation transform of a few degrees, then shifts the frame down a few times. The result is the 50x50 view is now much larger looking. Here's the code: // a simple 50x50 view UIView *redThing = [[UIView alloc] initWithFrame:CGRectMake(50, 50, 50, 50)]; redThing.backgroundColor = [UIColor redColor]; [self.view addSubview:redThing]; // rotate a small amount (as long as it's not 90 or 180, etc.) redThing.transform = CGAffineTransformRotate(redThing.transform, 0.1234); // move the view down 2 pixels CGRect newFrame = CGRectMake(redThing.frame.origin.x, redThing.frame.origin.y + 2, redThing.frame.size.width, redThing.frame.size.height); redThing.frame = newFrame; // move the view down another 2 pixels newFrame = CGRectMake(redThing.frame.origin.x, redThing.frame.origin.y + 2, redThing.frame.size.width, redThing.frame.size.height); redThing.frame = newFrame; // move the view down another 2 pixels newFrame = CGRectMake(redThing.frame.origin.x, redThing.frame.origin.y + 2, redThing.frame.size.width, redThing.frame.size.height); redThing.frame = newFrame; // move the view down another 2 pixels newFrame = CGRectMake(redThing.frame.origin.x, redThing.frame.origin.y + 2, redThing.frame.size.width, redThing.frame.size.height); redThing.frame = newFrame; So, what the heck is going on? Now, if I move the view by applying a translation transform, it works just fine. But that's not what I want to do and this should work anyway. Any ideas?

  • How to add values to a JSON object?

    - by Damiano
    Hello everybody, I have created an array with: var msg = new Array(); then, I have a function that add values to this array, this function is: function add(time, user, text){ var message = [time, user, text]; if (msg.length >= 50) msg.shift(); msg.push(message); } As you can see, if the array has 50 or more elements I remove the first with .shift(). Then I add an array as element. Ok, the code works perfectly, but now I have to loop the msg array to create a JSON obj. The JSON object should has this format: var obj = [ {'time' : time, 'user' : user, 'text' : text}, {'time' : time, 'user' : user, 'text' : text}, {'time' : time, 'user' : user, 'text' : text} ] I mean...i have to loop msg array and then store all the values inside the JSON object. I do not know how to "concatenate" the element of the array inside json obj. Could you help me? Thank you very much in advance!

  • Expression Encoder - Limitations for file Dimension - min size of 64 * 64 and must be a multiple of

    - by PortageMonkey
    I receive error messages when attempting to encode files in Expression Encoder when the file width or height is not a multiple of four, or is smaller than 64. I have been able to find very little in the documentation / web searches on this, and nothing that explains what settings may cause / alleviate these limitations. I assume it has something to do with the underlying data type. Error Message: Invalid Width Specified. The value must be an integer between 64 - and 4096 and be a multiple of 4. Can anyone provide further details on why / what settings can be manipulated to change this behavior: I.E. quality, compression etc.

  • Is it possible to get the parsed text of a SqlCommand with SqlParameters?

    - by Burg
    What I am trying to do is create some arbitrary sql command with parameters, set the values and types of the parameters, and then return the parsed sql command - with parameters included. I will not be directly running this command against a sql database, so no connection should be necessary. So if I ran the example program below, I would hope to see the following text (or something similar): WITH SomeTable (SomeColumn) AS ( SELECT N':)' UNION ALL SELECT N'>:o' UNION ALL SELECT N'^_^' ) SELECT SomeColumn FROM SomeTable And the sample program is: using System; using System.Data; using System.Data.SqlClient; namespace DryEraseConsole { class Program { static void Main(string[] args) { const string COMMAND_TEXT = @" WITH SomeTable (SomeColumn) AS ( SELECT N':)' UNION ALL SELECT N'>:o' UNION ALL SELECT @Value ) SELECT SomeColumn FROM SomeTable "; SqlCommand cmd = new SqlCommand(COMMAND_TEXT); cmd.CommandText = COMMAND_TEXT; cmd.Parameters.Add(new SqlParameter { ParameterName = "@Value", Size = 128, SqlDbType = SqlDbType.NVarChar, Value = "^_^" }); Console.WriteLine(cmd.CommandText); Console.ReadKey(); } } } Is this something that is achievable using the .net standard libraries? Initial searching says no, but I hope I'm wrong.

  • How can I detect if a file is binary (non-text) in python?

    - by grieve
    How can I tell if a file is binary (non-text) in python? I am searching through a large set of files in python, and keep getting matches in binary files. This makes the output look incredibly messy. I know I could use grep -I, but I am doing more with the data than what grep allows for. In the past I would have just searched for characters greater than 0x7f, but utf8 and the like make that impossible on modern systems. Ideally the solution would be fast, but any solution will do.

  • What's the best way to return a random line in a text file using C?

    - by jeremy Ruten
    What's the best way to return a random line in a text file using C? It has to use the standard I/O library (<stdio.h>) because it's for Nintendo DS homebrew. Clarifications: Using a header in the file to store the number of lines won't work for what I want to do. I want it to be as random as possible (the best being if each line has an equal probability of being chosen as every other line.) The file will never change while the program is being run. (It's the DS, so no multi-tasking.)
