问题 Android - What is the maximum file size that setMaxFileSize can be set to in respect to Androids mediarecorder? I know it's somewhere between 4147483650 and 5147483650. Why is there a limit in the first place? I'm recording on to a SDCARD, detecting the size of the cards space before we run.

问题 Answered I recorded an Excel macro (and saved it in my personal macro workbook) to create a pivot table and was hoping that I would be able to use it on multiple worksheets. The code works fine when I run it on spreadsheets on my computer, but will not run on other computers or if I try to run it in the VBA editor. It keeps giving the following error: http://imgur.com/xNU1R2F (Cannot find PivotTable source file) The thing is, the file is saved in that location under the same exact name. I

问题 I have a CSV containing numbers which I am trying to convert to floats. filename = "filename.csv" enclosed_folder = "path/to/Folder" full_path = os.path.join(enclosed_folder,filename) with open(full_path) as input_data: temp = input_data.readlines() n = len(temp) #int(temp.pop(0)) matrix = [x.split(" ") for x in temp] for i in range(n): for j in range(n): matrix[i][j] = float(matrix[i][j]) input_data.close() When I open the file in any text editor, it does not show the \n at the end of each

问题 I have the following code which I want to make it so that board now has the value of new_board and vice versa. Since they are both pointers I thought I could just swap the addresses they point to. When I print in print2() the addresses are appropriately swapped. However, when I print in print1() the addresses have somehow swapped back, which doesn't make any sense to me. Further if I print out the values in the board at print2() they are also correct. main(){ char *new_board = (char *)malloc

问题 When I deploy my application to my unlocked device (Lumia 1020), VS is giving me an error that I am using VS 2013 and it is in admin mode. How can I fix it? Thanks. 回答1: I just had the same error when trying to deploy a release build to my Lumia 920. As Shawn Kendrot mentions in the comments, I already had the release build deployed to my phone as installed via the store. Switching to a debug build and deploying that one instead worked. 来源： https://stackoverflow.com/questions/22132635/error

问题 I was getting the following error upon running a certain function: django.contrib.contenttypes.models.DoesNotExist: ContentType matching query does not exist. Based upon ContentType matching query does not exist on post_syncdb I tried doing from django.contrib.contenttypes.management import update_all_contenttypes update_all_contenttypes() # make sure all content types exist at the beginning of that function.

问题 I installed SublimeREPL, but every time I try to launch the REPL, I get a dialog showing the error "OSError(2, 'No such file or directory')". I have Scala 2.10 installed using MacPorts.
