  • ASP.NET MVC Default URL View

    - by Moose Factory
    I'm trying to set the Default URL of my MVC application to a view within an area of my application. The area is called "Common", the controller "Home" and the view "Index". I've tried setting the defaultUrl in the forms section of web.config to "~/Common/Home/Index" with no success. I've also tried mapping a new route in global.asax, thus: routes.MapRoute( "Area", "{area}/{controller}/{action}/{id}", new { area = "Common", controller = "Home", action = "Index", id = "" } ); Again, to no avail.

  • Making Visual C++ DLL from C++ class

    - by prosseek
    I have the following C++ code to make dll (Visual Studio 2010). class Shape { public: Shape() { nshapes++; } virtual ~Shape() { nshapes--; }; double x, y; void move(double dx, double dy); virtual double area(void) = 0; virtual double perimeter(void) = 0; static int nshapes; }; class __declspec(dllexport) Circle : public Shape { private: double radius; public: Circle(double r) : radius(r) { }; virtual double area(void); virtual double perimeter(void); }; class __declspec(dllexport) Square : public Shape { private: double width; public: Square(double w) : width(w) { }; virtual double area(void); virtual double perimeter(void); }; I have the __declspec, class __declspec(dllexport) Circle I could build a dll with the following command CL.exe /c example.cxx link.exe /OUT:"example.dll" /DLL example.obj When I tried to use the library, Square* square; square->area() I got the error messages. What's wrong or missing? example_unittest.obj : error LNK2001: unresolved external symbol "public: virtual double __thiscall ... Square::area(void)" (?area@Square@@UAENXZ) ADDED Following wengseng's answer, I modified the header file, and for DLL C++ code, I added #define XYZLIBRARY_EXPORT However, I still got errors. example_unittest.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: __th iscall Circle::Circle(double)" (__imp_??0Circle@@QAE@N@Z) referenced in function "protected: virtual void __thiscall TestOne::SetUp(void)" (?SetUp@TestOne@@MAEXXZ) example_unittest.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: __th iscall Square::Square(double)" (__imp_??0Square@@QAE@N@Z) referenced in function "protected: virtual void __thiscall TestOne::SetUp(void)" (?SetUp@TestOne@@MAEXXZ) example_unittest.obj : error LNK2001: unresolved external symbol "public: virtual double __thiscall Square::area(void)" (?area@Square@@UAENXZ) example_unittest.obj : error LNK2001: unresolved external symbol "public: virtual double __thiscall Square::perimeter(void)" (?perimeter@Square@@UAENXZ) example_unittest.obj : error LNK2001: unresolved external symbol "public: virtual double __thiscall Circle::area(void)" (?area@Circle@@UAENXZ) example_unittest.obj : error LNK2001: unresolved external symbol "public: virtual double __thiscall Circle::perimeter(void)" (?perimeter@Circle@@UAENXZ)

  • Recover Lost Form Data in Firefox

    - by Asian Angel
    Have you ever filled in a text area or form in a webpage and something happens before you can finish it? If you like the idea of recovering that lost data then you will want to have a look at the Lazarus: Form Recovery extension for Firefox. Lazarus: Form Recovery in Action For our first example we chose the comment text box area for one of the articles here at the website. As you can see we were not finished typing in the whole comment yet… Notice the “Lazarus Icon” in the lower right corner. Note: We simulated accidental tab closures for our two examples. After getting our webpage opened up again all of our text was gone. Right clicking within the text area showed two options available…”Recover Text & Recover Form”. Notice that our lost text was listed as a “sub menu”…this could be extremely useful in matching up the appropriate text to the correct webpage if you had multiple tabs open before something happened. Click on the correct text listing to insert it. So easy to finish writing our comment without having to start from zero again. In our second example we chose the sign-up form page for the website. As before we were not finished filling in the form… Getting the webpage opened back up showed the same problem as before…all the entered text was lost. This time we right clicked in the browser window area and there was that wonderful “Recover Form Command” waiting to be used. One click and… All of our lost form data was back and we were able to finish filling in the form. For those who may be interested you can disable Lazarus: Form Recovery on individual websites using the “Context Menu” for the “Status Bar Icon” Options There are three sections in the options and you should take a quick look through them to make any desired modifications in how Lazarus: Form Recovery functions. The first “Options Area” focuses on display/access for the extension. The second “Options Area” allows you to expand the type of data retained, enable removal of data within a given time frame, set up a password, disable search indexing, and enable form data retention while in “Private Browsing Mode”. The third “Options Area” focuses on the Lazarus database itself. Conclusion If you have ever lost text area or form data before then you know how much time could be lost in starting over. Lazarus: Form Recovery helps provide a nice backup solution to get you up and running once again with a minimum of effort.

  • Change the colour of ablines on ggplot

    - by Sarah
    Using this data I am fitting a plot: p <- ggplot(dat, aes(x=log(Explan), y=Response)) + geom_point(aes(group=Area, colour=Area))+ geom_abline(slope=-0.062712, intercept=0.165886)+ geom_abline(slope= -0.052300, intercept=-0.038691)+ scale_x_continuous("log(Mass) (g)")+ theme(axis.title.y=element_text(size=rel(1.2),vjust=0.2), axis.title.x=element_text(size=rel(1.2),vjust=0.2), axis.text.x=element_text(size=rel(1.3)), axis.text.y=element_text(size=rel(1.3)), text = element_text(size=13)) + scale_colour_brewer(palette="Set1") The two ablines represent the phylogenetically adjusted relationships for each Area trend. I am wondering, is it possible to get the ablines in the same colour palette as their appropriate area data? The first specified is for Area A, the second for Area B. I used: g <- ggplot_build(p) to find out that the first colour is #E41A1C and the second is #377EB8, however when I try to use aes within the +geom_abline command to specify these colours i.e. p <- ggplot(dat, aes(x=log(Explan), y=Response)) + geom_point(aes(group=Area, colour=Area))+ geom_abline(slope=-0.062712, intercept=0.165886,aes(colour='#E41A1C'))+ geom_abline(slope= -0.052300, intercept=-0.038691,aes(colour=#377EB8))+ scale_x_continuous("log(Mass) (g)")+ theme(axis.title.y=element_text(size=rel(1.2),vjust=0.2), axis.title.x=element_text(size=rel(1.2),vjust=0.2), axis.text.x=element_text(size=rel(1.3)), axis.text.y=element_text(size=rel(1.3)), text = element_text(size=13)) + scale_colour_brewer(palette="Set1") It changes the colour of the points and adds to the legend, which I don't want to do. Any advice would be much appreciated!

  • cant calculate width of elements

    - by Kein
    I try to get width of dom objects: function resizeArea(){ var width = 0; area.children().each(function(i){ alert(this.offsetWidth); width += this.offsetWidth; }); area.css('width', width); } In get results: Chrome: 800 Opera: 708 FF: 783 IE: 714 But if see it in firebug, dragonfly and other debuggers i see correct 908px. I don't know where porblem. I run this fun after domloaded. Here is HTML and css of block: <div class="scroll_area" id="scroll"> <div class="area" id="area"> <div class="category"> [..] </div> </div> </div> <style> #scroll { position:realtive; width: 800px, heght: 400px; } #area { position:absolute; left: 0; top: 0; } #area .category, #area .category .text, #area .category .image{ width: 200px } </style> And that interesting. This function later work correctly, only at first run, for first calculating.

  • Mathmatic errors in basic C++ program

    - by Heather
    I am working with a basic C++ program to determine the area and perimeter of a rectangle. My program works fine for whole numbers but falls apart when I use any number with a decimal. I get the impression that I am leaving something out, but since I'm a complete beginner, I have no idea what. Below is the source: #include <iostream> using namespace std; int main() { // Declared variables int length; // declares variable for length int width; // declares variable for width int area; // declares variable for area int perimeter; // declares variable for perimeter // Statements cout << "Enter the length and the width of the rectangle: "; // states what information to enter cin >> length >> width; // user input of length and width cout << endl; // closes the input area = length * width; // calculates area of rectangle perimeter = 2 * (length + width); //calculates perimeter of rectangle cout << "The area of the rectangle = " << area << " square units." <<endl; // displays the calculation of the area cout << "The perimeter of the rectangle = " << perimeter << " units." << endl; // displays the calculation of the perimeter system ("pause"); // REMOVE BEFORE RELEASE - testing purposes only return 0; }

  • UIView drawRect: when you draw a line, the rect area will be clear so the previous drawing is gone

    - by snakewa
    It is quite hard to tell so I upload an image to show my problem: http://i42.tinypic.com/2eezamo.jpg Basically in drawRect, I will draw the line from touchesMoved as finger touches and I will call "needsDisplayInRect" for redraw. But I found that the first line is done, the second line will clear the rect part, so some previouse drawing is gone. Here is my implementation: enter code here -(void) drawRect:(CGRect)rect{ //[super drawRect: rect]; CGContextRef context = UIGraphicsGetCurrentContext(); [self drawSquiggle:squiggle at:rect inContext:context]; } - (void)drawSquiggle:(Squiggle *)squiggle at:(CGRect) rect inContext:(CGContextRef)context { CGContextSetBlendMode(context, kCGBlendModeMultiply); UIColor *squiggleColor = squiggle.strokeColor; // get squiggle's color CGColorRef colorRef = [squiggleColor CGColor]; // get the CGColor CGContextSetStrokeColorWithColor(context, colorRef); NSMutableArray *points = [squiggle points]; // get points from squiggle // retrieve the NSValue object and store the value in firstPoint CGPoint firstPoint; // declare a CGPoint [[points objectAtIndex:0] getValue:&firstPoint]; // move to the point CGContextMoveToPoint(context, firstPoint.x, firstPoint.y); // draw a line from each point to the next in order for (int i = 1; i < [points count]; i++) { NSValue *value = [points objectAtIndex:i]; // get the next value CGPoint point; // declare a new point [value getValue:&point]; // store the value in point // draw a line to the new point CGContextAddLineToPoint(context, point.x, point.y); } // end for CGContextStrokePath(context); }

    hi! i hav a panel and i m trying to remove labels from it which were added to it during run-time. but when labels are removed succesfully i m not able to use the space,left by that label,again to add any label to it. thanks in anticipation of the solution. here is the relevant code snippet: to add label to the panel: JLabel jl = new JLabel(); jl.setOpaque(true); jl.setIcon(new ImageIcon("D:/Project/router2.jpg")); jl.setBounds(x, y,jl.getPreferredSize().width,jl.getPreferredSize().height); for(Component c :lcomponent) { flag=true; Rectangle r4=c.getBounds(); int x1=(int) r4.getX(); int y1=(int) r4.getY(); Rectangle r5 = new Rectangle(new Point(x1-60, y1-60),new Dimension(170,170)); if(r5.contains(p)){ //To ensure that two labels do not overlap or are too close flag = false; // to each other break; }} if(flag) { p2.add(jl); //p2 is a panel Component c2 = p2.getComponentAt(x,y); p2.repaint(); lcomponent.add(c2); //lcomponent is an ArrayList<Component> to store all the labels added to the panel } 2.to remove the label: p2.remove(); p2.repaint();

    I have been searching for this for quite some time now. I am using OTRS 2.4.7 and installed the FAQ package version 1.6.5. Everything seems to work fine. When I am logged in, I can create articles and other users have the ability to browse the articles. I want to be able to allow access to any anonymous non-user to be able to read these articles. Can anyone shed some light on how to allow this type of access? Thanks

  • Which are the RDBMS that minimize the server roundtrips? Which RDBMS are better (in this area) than

    - by user193655
    When the latency is high ("when pinging the server takes time") the server roundtrips make the difference. Now I don't want to focus on the roundtrips created in programming, but the roundtrips that occur "under the hood" in the DB engine, so the roundtrips that are 100% dependant on how the RDBMS is written itself. I have been told that FireBird has more roundtrips than MySQL. But this is the only information I know. I am currently supporting MS SQL but I'd like to change RDBMS (because I use Express Editions and in my scenario they are quite limiting from the performance point of view), so to make a wise choice I would like to include also this point into "my RDBMS comparison feature matrix" to understand which is the best RDBMS to choose as an alternative to MS SQL. So the bold sentence above would make me prefer MySQL to Firebird (for the roundtrips concept, not in general), but can anyone add informations? And MS SQL where is it located? Is someone able to "rank" the roundtrip performance of the main RDBMS, or at least: MS SQL, MySql, Postegresql, Firebird (I am not interested in Oracle since it is not free, and if I have to change I would change to a free RDBMS). Anyway MySql (as mentioned several times on stackoverflow) has a not clear future and a not 100% free license. So my final choice will probably dall on PostgreSQL or Firebird. Additional info: somehow you can answer my question by making a simple list like: MSSQL:3; MySQL:1; Firebird:2; Postgresql:2 (where 1 is good, 2 average, 3 bad). Of course if you can post some links where the roundtrips per RDBMSs are compared it would be great

  • Changing the width of dropdown area in flex combobox.

    - by DineshDu
    I have a combobox which gets populated by a remote method. I need to set the dropdownwidth of the combobox to the maximum length of the item in the combobox. I am able to achieve it by the following code. But if the resolution of the screen changes, the result is not similar. Is there any way to find the display width of the text in the dropdown? private function getGroupData(resultEvent:ResultEvent):void{ viewCbx.dataProvider = resultEvent.result as ArrayCollection; var comboDp:ArrayCollection = viewCbx.dataProvider as ArrayCollection; var dropWidth:int = 0; for each(var obj:Object in comboDp){ if(obj.groupName.length > dropWidth){ dropWidth = obj.groupName.length; } } viewCbx.dropdownWidth = dropWidth*6; }
