My question is, at present I used to include the header and footer of the page using: and But now, I have separated the page content also. So, if user clicks on a page, say products, it has to load the JSP file which is situated in: includes/pages/products.jsp So, the link to the user is like: Products . So, I have to get the p value and display the page based on it. Following is what I have done so far. So, how do I place the value of variable "p" in position of "page_name" ? Or, is there any other method

Right now to display it Im using the Allegro API which has a function: al_draw_rotated_bitmap(OBJECT_TO_ROTATE,CENTER_X,CENTER_Y,X ,Y,DEGREES_TO_ROTATE_IN_RADIANS); so with this I can make my fan effect easily. The problem is then knowing which card is under the mouse. To do this I thought of doing a polygon collision test. I'm just not sure how to rotate the 4 points on the card to make up the polygon. I basically need to do the same operation as Allegro. for example, the 4 points of

Also my method is called by an

I have tried with NSDistributionNotification but its practically useless in a sandboxed app. I looked up XPC and hoped it will work but I just dont know how to get it to work with the helper. So far I have done this using XPC. Main App NSXPCInterface *remoteInterface = [NSXPCInterface interfaceWithProtocol:@protocol(AddProtocol)]; NSXPCConnection *xpcConnection = [[NSXPCConnection alloc] initWithServiceName:@

I don't want to reference the other application directly or otherwise have an accessor in the project I'm testing. What I've managed to do so far is create a link to the other project's Web.config file in my TestUtility project, and I've set it to Copy if newer . It's the only Web.config in my test project's root folder, but WebConfigurationManager.OpenWebConfiguration(null) seems to

But,the problem is, the user can simply click on the back button of the browser and can go back to payment page, if he initiates a "pay now" again,there is a chance of multiple transaction and duplication of ref ids. So my question is: is there some way I can redirect the user to a custom page when he clicks on back button which says "Session expired, so transaction has been cancelled." so that we avoid duplication

Where either the divisor or dividend is zero, the corresponding element in the output array should be zero. (This is the default output when the divisor is zero, but np.nan is the default output when the dividend is zero.) 回答1: This still tries to divide by 0, but it gives the correct result: np.where(b==0, 0, a/b) To avoid doing the divide-by-zero, you can do: m = b!=0 c = np.zeros_like(a) np

I've tried the following: $(".sidebar").css({'height':($(".content").height()+'px'}); $(".sidebar").height($(".content").height()); var highestCol = Math.max($('.sidebar').height(),$('.content').height()); $('.sidebar').height(highestCol); None of these are working. For the .content I don't have any height since will increase or decrease based on the content. Please help me. I have to finish up a web page today and this (simple) thing

Lets say I have one repo in C:/folder1 and C:/folder2 I want to clone the work in folder1 into folder2 . What would I type into the command prompt to do this? It seems that often when cloning a URL is provided rather then a file path, however, at this moment I am just practicing and trying to get use to Git. 回答1: cd / d c : \ git clone C : \folder1 folder2 From the documentation for git clone : For local repositories, also supported by git natively, the following syntaxes may be

Consider separating your class into separate interfaces so that each class only gets an object with the interface it needs. For example: interface Incrementable {
