  • Automatically resize TableLayoutPanel

    - by Armagan
    I have a programmatically created TableLayoutPanel. It works fine but I couldn't find something: how can I make it size columns automatically when the form is resized? The panel is set to Dock.Top and when I resize the form instead of sizing every column as percents, only last column grows. What can I do for this? Here's how I add ColumnStyle for each column: this.tablePanelFilter.ColumnStyles.Add( new ColumnStyle(SizeType.Percent,Convert.ToSingle( Math.Ceiling((decimal)100 / (decimal)columnCount))));

  • Spawning worker threads

    - by LB
    In C#, How would one go about spawning multiple threads and then sequentially adding results to a list before returning the entire result set? What are some best practices? I'm so far using an ManualResetEvent to signal when the last element has been processed by a thread. But when it returns, I need to have them consolidate the result sets in sequential order so that we don't get into contention issues with the return value list (total results).

  • which is the most secure way to check variables type javascript

    - by mck89
    Hi, i need to check the type of a variable in javascript, i know 3 ways to do it: instanceof operator: if(a instanceof Function) typeof operator: if(typeof a=="function" toString method (jQuery uses this): Object.prototype.toString.call(a) == "[object Function]" Which is the most secure way to do type checking beetween these solutions? and why? Please don't tell me that the last solution is better only because jQuery uses that.

    It is possible to reference a generic method using a Lambda Expression Object? For example, having: TheObject: public abstract class LambdaExpression : Expression TheMethod (an extension method of LINQ): public static TSource Last<TSource>( this IEnumerable<TSource> source ) I'm trying to create an instance of TheObject, that references to TheMethod. How do you do such thing?

  • Menu floating to the right on IE and to the left in FF

    - by the_drow
    I am working on a website that has a menu which behaves correctly on FF but not on IE (as usuall). On IE it floats to the right while it should float to the left, however if float is set to none it behaves almost correctly, attaching the onto the top of the container. Here's the css: #navigation_wrap { background: url(../images/ltr/nav_bg.png); height: 34px; width: 954px; } .btn_login { float: right; margin: 4px 4px 0 0; } .navigation { float: left; } .navigation ul { list-style: none; margin: 8px 0 0 15px; } .navigation ul li { border-right: 1px solid white; float: left; padding: 0 12px 0 12px; } .navigation ul li.last { border: none; } .navigation ul li a { color: white; font-size: 14px; text-decoration: none; } .navigation ul li a:hover { text-decoration: underline; } .navigation ul li a.active { font-weight: bold; } And here's the html: <div id="navigation_wrap"> <div class="navigation"> <ul> <li><a class="active" href="default.asp">Home Page</a></li> <li><a class="" href="faq.asp">FAQ</a></li><li><a class="" href="articles.asp">Articles</a></li> <li><a class="" href="products.asp">Packages &amp; Pricing</a></li> <li><a class="" href="gp.asp?gpid=15">test1</a></li> <li><a class=" last" href="gp.asp?gpid=17">test asher</a></li> </ul> </div> <div class="btn_login"> ... </div> </div> I hope anyone would have an idea. Thanks, Omer.

  • Serious Memory Clash: Variables clashing in C

    - by Soham
    int main(int argc, char*argv[]) { Message* newMessage; Asset* Check; //manipulation and initialization of Check, so that it holds proper values. newMessage = parser("N,2376,01/02/2011 09:15:01.342,JPASSOCIAT FUTSTK 24FEB2011,B,84.05,2000,0,0",newMessage); // MessageProcess(newMessage,AssetMap); printf("LAST TRADE ADDRESS %p LAST TRADE TIME %s\n",Check->TradeBook,Check->Time); } Message* parser(char *message,Message* new_Message) { char a[9][256]; char* tmp =message; bool inQuote=0; int counter=0; int counter2=0; new_Message = (Message*)malloc(sizeof(Message)); while(*tmp!='\0') { switch(*tmp) { case ',': if(!inQuote) { a[counter][counter2]='\0'; counter++; counter2=0; } break; case '"': inQuote=!inQuote; break; default: a[counter][counter2]=*tmp; counter2++; break; } tmp++; } a[counter][counter2]='\0'; new_Message->type = *a[0]; new_Message->Time = &a[2][11]; new_Message->asset = a[3]; if(*a[4]=='S') new_Message->BS = 0; else new_Message->BS = 1; new_Message->price1=atof(a[5]); new_Message->shares1=atol(a[6]); new_Message->price2=atof(a[7]); new_Message->shares2=atol(a[8]); new_Message->idNum = atoi(a[1]); return(new_Message); } Here there is a serious memory clash, in two variables of different scope. I have investigated using gdb and it seems the address of new_Message->Time is equalling to the address of Check->Time. They both are structures of different types I am trying to resolve this issue, because, when parser changes the value of new_Message->Time it manipulates the contents of Check-Time Please do suggest how to solve this problem. I have lost(spent) around 10 hours and counting to resolve this issue, and tons of hair. Soham

    Good Morning, Just a quick question what this field actually means? I am trying to create an export script which follows this standard: lname varchar(30) **NOT NULL**, So if last name is_nullable=yes then would I put NULL rather than NOT NULL at the *'d code. Many Thanks, Joel

  • PIL's Image.show() brings up *two* different viewers

    - by DarenW
    When toying with images in the python shell, I use image.show(), where image is an instance of Image. Long ago nothing happened, but after defining a symlink to mirage named "xv", I was happy. The last few days, show() will bring up both ImageMagick's display and also Mirage. It's not clear where show() gets information on what to run. Documentation wasn't helpful. How to make it behave and bring up only what it thinks is xv?

  • Next programming paradigm for CBE/GPU in the next years

    - by Werner
    Hi, in the last five years, there has been a rise in the use of GPU and CBE for parallelization of applications. Around 2005-2007 verything seemed to be programmed by hand, C, etc. Afterwards new unifying alternatives emerged like CUDA for GPU and lastly OpenCL. What do you think will be the programming paradigm for GPU/CBE in the forthcoming years? My vote goes for OpenCL Thanks

  • Lighttpd check request headers in configuration

    - by Mike Hayes
    Hi I was wondering if it was possible in the configuration of Lighttpd to read request headers, I've searched and searched.. apparently it's not possible. For example, conditional configuration based upon IP address: $HTTP["remoteip"] == "0.0.0.0" { // Do something } Is there something similar to check headers, for example: $HTTP["X-Some-Header"] == "Value" { // Do something } I'm thinking there isn't but thought I would post here as a last resort. Google didn't help much, and Lighttpd documentation would suggest this is not possible. Thanks Mike

  • Learning PHP: Good examples of "build-this" based lessons?

    - by DavidR
    Last summer I learned HTML and CSS for a job, mainly through tutorials and a sort of "build this" method, that is, I'm given a goal and have to try to figure out how to build it myself. Is there a place with some examples to teach someone with this method? My boss wants to get me going on PHP this summer, and I need to refamiliarize myself with it over the next week. Most people send me to Php.net to follow the documentation, is there another good method out there?

  • Algorithm for finding symmetries of a tree

    - by Paxinum
    I have n sectors, enumerated 0 to n-1 counterclockwise. The boundaries between these sectors are infinite branches (n of them). The sectors live in the complex plane, and for n even, sector 0 and n/2 are bisected by the real axis, and the sectors are evenly spaced. These branches meet at certain points, called junctions. Each junction is adjacent to a subset of the sectors (at least 3 of them). Specifying the junctions, (in pre-fix order, lets say, starting from junction adjacent to sector 0 and 1), and the distance between the junctions, uniquely describes the tree. Now, given such a representation, how can I see if it is symmetric wrt the real axis? For example, n=6, the tree (0,1,5)(1,2,4,5)(2,3,4) have three junctions on the real line, so it is symmetric wrt the real axis. If the distances between (015) and (1245) is equal to distance from (1245) to (234), this is also symmetric wrt the imaginary axis. The tree (0,1,5)(1,2,5)(2,4,5)(2,3,4) have 4 junctions, and this is never symmetric wrt either imaginary or real axis, but it has 180 degrees rotation symmetry if the distance between the first two and the last two junctions in the representation are equal. Edit: This is actually for my research. I have posted the question at mathoverflow as well, but my days in competition programming tells me that this is more like an IOI task. Code in mathematica would be excellent, but java, python, or any other language readable by a human suffices. Here are some examples (pretend the double edges are single and we have a tree) http://www2.math.su.se/~per/files.php?file=contr_ex_1.pdf http://www2.math.su.se/~per/files.php?file=contr_ex_2.pdf http://www2.math.su.se/~per/files.php?file=contr_ex_5.pdf Example 1 is described as (0,1,4)(1,2,4)(2,3,4)(0,4,5) with distances (2,1,3). Example 2 is described as (0,1,4)(1,2,4)(2,3,4)(0,4,5) with distances (2,1,1). Example 5 is described as (0,1,4,5)(1,2,3,4) with distances (2). So, given the description/representation, I want to find some algorithm to decide if it is symmetric wrt real, imaginary, and rotation 180 degrees. The last example have 180 degree symmetry. (These symmetries corresponds to special kinds of potential in the Schroedinger equation, which has nice properties in quantum mechanics.)

  • Getting a KeyError in DB backend of django-digest

    - by rtmie
    I have just started to integrate django_digest into my app. As a start I have added the @httpdigest decorator to one of my views. If I try to connect to it I get a KeyError exception thrown in django_digest/backend/db.py . Depending on which db I configure I get a different KeyError in a different location. I am using Django 1.2.1, with MySql (also tested with sqlite). I am using the default values for all the settings options. As far as I can see I have followed all instructions but am struggling all day with this. I am using the repository versions of django-digest and python-digest. Any steer would be greatly appreciated.

  • WPF Listbox display next element after SelectedItem

    - by Daniil Harik
    I have TextBox and ListBox with bunch of elements. TextBox has KeyDown event handler, the idea behind this is to allow user to press up and down keys to scroll inside ListBox while focus is on TextBox. When user presses "down key" several times, selected element becomes last visible element on screen. If user has reached bottom of visible list element on screen, I want him to see next element after selected element as well.
