  • Silverlight MVVM add record from user control

    - by strattonn
    I have a User Control for searching container numbers. If the user enters a container number that's new to the system then I want to tell the VM "I have a new record to add". The MVVM method avoids using Events to communicate with the VM as they create code-behind. Should I create a Dependency Property to trigger the VM but I don't think I've seen other controls with a "NewRecord" property? Any thoughts?

  • Why does this crash: stringByAppendingFormat

    - by Emil
    Hey. My code crashes at this function (at the stringByAppendingFormat: with error objc_msgSend() selector name: stringByAppendingFormat). This is that line: // imagesPath = ...iPhone Simulator/4.0/Applications/NUMBERS/Documents/images UIImage *image = [[UIImage alloc] initWithContentsOfFile:[imagesPath stringByAppendingFormat:@"/%d.png", [[self.postsArrayID objectAtIndex:row] intValue]]]; Could it have something to do with the retaining of objects? Thanks :)

  • Latency on mobile networks (Android)

    - by Meep3D
    I am planning to give mobile phone development a shot and was thinking about making some simple multiplayer games. I know latency over local wifi is probably fine but what are the issues with latency over GPRS/3G? I've searched and the best I've seen is someone saying it was 'high', without presenting any concrete numbers. I suppose latency fluctuations are important as well - does anyone have any info on this?

  • How can i optimize this python code

    - by RandomVector
    def maxVote(nLabels): count = {} maxList = [] maxCount = 0 for nLabel in nLabels: if nLabel in count: count[nLabel] += 1 else: count[nLabel] = 1 #Check if the count is max if count[nLabel] > maxCount: maxCount = count[nLabel] maxList = [nLabel,] elif count[nLabel]==maxCount: maxList.append(nLabel) return random.choice(maxList) nLabels contains a list of integers. The above function returns the integer with highest frequency, if more than one have same frequency then a randomly selected integer from them is returned. E.g. maxVote([1,3,4,5,5,5,3,12,11]) is 5

    Hi everyone, Is_numeric() as well as is_int() returns false if the value is 0. What can i do instead to verify that a specific value is numbers only in PHP? Are we heading straight for the Regular Expressions camp, or are there some nice, handy feature for this out there already? Thanks!

  • C++ STL list vs set

    - by mokaschitta
    Hi, what of those two is faster for random insertions and deletions? I guess list, having the values as the keys as it is with sets seems to be attractive too though. Is performance similar for iterating over the whole container? Thanks!

  • C++: Unitialized variables garbage

    - by Hardware Problem
    int myInt; cout << myInt; // Garbage like 429948, etc If I output and/or work with unitialized variables in C++, what are their assumed values? Actual values in the memory from the "last user"? e.g.: Program A is closed, it had an int with the value 1234 at 0x1234 - I run my program, myInt gets the address 0x1234, I output it like above - 1234 Is it just random garbage?
