    - by korben
    i got this inside a button inside a datalist CommandName="<%# Container.ItemIndex %>" when i click the button, i'm expecting commandname to = 0, then 1, then 2, etc, as the datalist progresses, and i'm using that value in the button click's c# but i'm getting this error, i'm pretty sure i'm using this exact setup on another page and i have no problems, any idea what's going on?

  • Having trouble getting GET variables from url.

    - by mchl
    Hey everyone, I'm having trouble with this algorithm to extract the get variables from a url and print them each on a new line like: x=y z=hello etc. but instead it prints a seemingly random section of the url with no newlines to the file. There must be a logic error of some kind but i just can't spot it. for(i_m=0;i_m<len_m;i_m++) { if(var_m[i_m]=='&') { fwrite(var_m+offset_m, 1, amp_m, echo_out); fputc('\n',echo_out); offset_m+=amp_m; amp_m=0; } amp_m++; } any help appreciated.

  • What to Learn after C++?

    - by Stephen Whitmore
    I have been learning C++ for a while now, I find it very powerful. But, the problem is the the level of abstraction is not much and I have to do memory management myself. What are the languages that I can use which uses a higher level of abstraction.

  • Call/Return feature of classic C++(C with Classes), what modern languages have it?

    - by AraK
    Hi, On page 57 of The Design and Evolution of C++, Dr. Stroustrup talks about a feature that was initially part of C with Classes, but it isn't part of modern C++(standard C++). The feature is called call/return. This is an example: class myclass { call() { /* do something before each call to a function. */ } return() { /* do something else after each call to a function. */ } ... }; I find this feature very interesting. Does any modern language have this particular feature?

  • Haskell: How to compose `not` with a function of arbitrary arity?

    - by Hynek -Pichi- Vychodil
    When I have some function of type like f :: (Ord a) => a -> a -> Bool f a b = a > b I should like make function which wrap this function with not. e.g. make function like this g :: (Ord a) => a -> a -> Bool g a b = not $ f a b I can make combinator like n f = (\a -> \b -> not $ f a b) But I don't know how. *Main> let n f = (\a -> \b -> not $ f a b) n :: (t -> t1 -> Bool) -> t -> t1 -> Bool Main> :t n f n f :: (Ord t) => t -> t -> Bool *Main> let g = n f g :: () -> () -> Bool What am I doing wrong? And bonus question how I can do this for function with more and lest parameters e.g. t -> Bool t -> t1 -> Bool t -> t1 -> t2 -> Bool t -> t1 -> t2 -> t3 -> Bool

  • How to call C++ function from C?

    - by claws
    I know this. Calling C function from C++: If my application was in C++ and I had to call functions from a library written in C. Then I would have used //main.cpp extern "C" void C_library_function(int x, int y);//prototype C_library_function(2,4);// directly using it. This wouldn't mangle the name C_library_function and linker would find the same name in its input *.lib files and problem is solved. Calling C++ function from C??? But here I'm extending a large application which is written in C and I need to use a library which is written in C++. Name mangling of C++ is causing trouble here. Linker is complaining about the unresolved symbols. Well I cannot use C++ compiler over my C project because thats breaking lot of other stuff. What is the way out? By the way I'm using MSVC

  • deep zoom is not displayed

    - by George2
    I am using VSTS 2008 + C# + .Net 3.5 + Windows Vista Enterprise x86. I have used Silverlight Deep Zoom composer tool to export my composed images into Siverlight type. Everything is previewed fine after export successful message (I select browse from browser). But when I click the Test.html in the exported project to show Deep Zoom effects from browser, nothing is displayed. Here is my screen snapshot. Any ideas what is wrong? http://i41.tinypic.com/2dac561.jpg EDIT 1: to my surprise, there is no clientbin folder in my exported project. I have made two screen snapshots for, my project folder generated by Deep Zoom Composer under Exported Data folder; the content of GeneratedImages folder under my project folder. Please refers them to, http://i42.tinypic.com/346ncec.jpg http://i42.tinypic.com/15zqkn9.jpg Any ideas what is wrong? thanks in advance, George

  • __declspec(dllimport) causes compiler crash on MSVC 2010

    - by Zero
    In a *.cpp file, trying to use a third party lib: #define DLL_IMPORT #include <thirdParty.h> // Third party header has code like: // #ifdef DLL_IMPORT // #define DLL_DECL __declspec(dllimport) // fatal error C1001: An internal error has occurred in the compiler. Alternative: #define NO_DLL #include <thirdParty.h> // Third party header has code like: // #elif defined(NO_DLL) // #define DLL_DECL // Compiles fine, but linker errors as can't find DLL functions // I can reproduce results by remove macros and #define all together and manually editing the third party files to have __declspec(dllimport) or not Has anyone come across anything similar, or can hint at the cause? (which is created using CMake). Above is actual example of 2 line *.cpp that crashes so it's narrowed down to something in the #include. The following also work fine: Compile the examples provided by the third party (they provide a *.sln) that use dllimport/export so it doesn't appear to be the fault of the library Compile the third party lib as part of the production project (so dllexport works fine) I've trawled the project settings pages of the two projects to try and spot differences, but have come up blank. Of course, it's possible I'm missing something as those settings pages are not the easiest to navigate. I'll get access to VS2008 in a day or so, so can compare with that. The third party library is MySql++.

  • SQL finding overlapping of times pass midnight (across 2 days)

    - by janechii
    Hi everyone, I know there are lots of these types of questions, but i didn't see one that was similar enough to my criteria. So i'd like to ask for your help please. The fields i have are just start and end which are of time types. I cannot involve any specific dates in this. If the time ranges don't go pass midnight across day, i'd just compare two tuples as such: end1 > start2 AND start1 < end2 (end points touching are not considered overlapped here.) But when I involve time range that pass (or at) midnight, this obviously doesn't work. For example, given: start | end --------+-------- 06:00PM | 01:00AM 03:00PM | 09:00PM Without involving dates, how can i achieve this, please. My assumption is, if end is less than start, then we're involving 2 days. I'm trying to do this in plain standard SQL, so just a simple and concise logic in the WHERE clause. Thank you everyone!

  • Get the number of packages transmitted per connection

    - by Daniel
    How do I get the number of packages transmitted per TCP connection? I am using Java, but i know I will have to fetch the number from the underlying OS, so this quastion applies to Linux and Windows operating systems and will have different answers for each of them, I assume. I need this information to profile the network load of an application which seems to send too many small packages by flushing the socket streams too often.

  • how to access child instances in a vector in c++

    - by tsubasa
    I have a parent class and child class (inherited from parent). In the child class, I have a member function named function_blah(); I used vector<parent*> A to store 5 parent instances, 3 child instances. So the total number of elements in the vector is 8. I can easily access to member functions of element A[0] to A[4], which are parent instances. But whenever I try to have access to member functions of element A[5] to A[7], the compiler complains that class parent has no member named 'function_blah' The way I access to elements is using index. e.x A[i] with i = 0..7. Is it correct? if not, how?

  • Need complete picture of virtual adress space

    - by claws
    Hello, This image gives a good picture about Virtual Adress space. But it only says half of the story. It only gives complete picture of User Adress space ie.. lower 50% (or 75% in some cases). What about the rest 50% (or 25%) which is occupied by the kernel. I know kernel also has so many different things like kernel modules , device drivers, core kernel itself. There must be some kind of layout right? What is its layout? If you say its Operating System dependent. I would say, there are two major operating systems Windows & Linux. Please give answer for any one these.

  • Localizing formatting functions instead of properties in VS.NET resources

    - by LexL
    I noticed that .NET framework uses formatting functions, generated the same way localizable string are. There is a resource file Resources.resx with resource string TestString. So you may use it in code like this: string localizableValue = Resources.TestString; Now, imagine you need a formattable localizable string, to use it in string.Format function. So everytime you use it, you have to write something like this: string localizableFormattedValue = string.Format(Resources.TestFormatString, someParam1, someParam2); The observation says that in .NET framework generated resource classes already include the above construction. So instead of string property, a string function is generated. The resulting code looks like this: string localizableFormattedValue = Resources.TestFormatString(someParam1, someParam2); The question is - how do they do this? Is it some custom Microsoft feature (resx generator) or I'm missing something obvious?

  • Heap Algorithmic Issue

    - by OberynMarDELL
    I am having this algorithmic problem that I want to discuss about. Its not about find a solution but about optimization in terms of runtime. So here it is: Suppose we have a race court of Length L and a total of N cars that participate on the race. The race rules are simple. Once a car overtakes an other car the second car is eliminated from the race. The race ends when no more overtakes are possible to happen. The tricky part is that the k'th car has a starting point x[k] and a velocity v[k]. The points are given in an ascending order, but the velocities may differ. What I've done so far: Given that a car can get overtaken only by its previous, I calculated the time that it takes for each car to reach its next one t = (x[i] - x[i+1])/(v[i] - v[i+1]) and I insert these times onto a min heap in O(n log n). So in theory I have to pop the first element in O(logn), find its previous, pop it as well , update its time and insert it in the heap once more, much like a priority queue. My main problem is how I can access specific points of a heap in O(log n) or faster in order to keep the complexity in O(n log n) levels. This program should be written on Haskell so I would like to keep things simple as far as possible EDIT: I Forgot to write the actual point of the race. The goal is to find the order in which cars exit the game

  • WCF or Sockets for Communication in a real-time environment?

    - by PieterG
    I have a scenario where I need to send a series of data across 2 clients. The data includes Serialized XML that will contain commands that the other client will need to react to. I will also need to send images across the wire as I need to provide a chat facility in the form of video/audio chat. I would like a single communication medium for both, as the number of messages/commands might be a few. WCF or Sockets?
