does 1 have idea updating hdf5 datasets h5py? assuming create dataset like: import h5py import numpy f = h5py.file('myfile.hdf5') dset = f.create_dataset('mydataset', data=numpy.ones((2,2),"=i4")) new_dset_value=numpy.zeros((3,3),"=i4") is possible extend dset 3x3 numpy array? you need create dataset "extendable" property. it's not possible change after initial creation of dataset. this, you need use "maxshape" keyword . value of none in maxshape tuple means that dimension can of unlimited size. so, if f hdf5 file: dset = f.create_dataset('mydataset', (2,2), maxshape=(none,3)) creates dataset of size (2,2), may extended indefinitely along first dimension , 3 along second. now, can extend dataset resize : dset.resize((3,3)) dset[:,:] = np.zeros((3,3),"=i4") the first dimension can increased as like: dset.resize((10,3))

i looking @ solving simple problem, eratosthenes sieve, using idiomatic scala, learning purposes. i've learned stream caches, not performant when determining nth element because it's o(n) complexity access memoisation of data, therefore not suitable situation. def primes(nums: stream[int]): stream[int] = { stream.cons(nums.head, primes((nums tail) filter (x => x % nums.head != 0))) } def ints(n: int): stream[int] = { stream.cons(n, ints(n + 1)) }; def nthprime(n: int): int = { val prim = primes(ints(2)).view take n tolist; return prim(n - 1); }; the integer stream problematic one. while prime number filtering done, jvm runs outofmemory. correct way achieve same functionality without using streams? basically take view of primes view of ints , display last element, without memoisation? i have had similar cases stream idea, did not need store it's values. in order consume stream witho...

if create progressbar via toolbox , add following line in code: progressbar1.value = 40; i able view progress bar when application runs. however, if try create 1 via code, unable view 1 - progress bar not visible. here code: progressbar progressbar1 = new progressbar(); progressbar1.location = new system.drawing.point(168, 180); progressbar1.height = 650; progressbar1.width = 340; progressbar1.minimum = 20; progressbar1.maximum = 100; progressbar1.value = 49; progressbar1.visible = true; if using windows forms must add form that: this.controls.add(progressbar1); if using wpf must that: this.children.add(progressbar1);

a simple, yet frustrating issue. i've bound datagrid local database play around , teach myself datasets , c#. binding data, no problem. custom fills (and sql selects), no problem. next comes adding record. so, add in following code: private void badd_click(object sender, eventargs e) { datarow newrow = abbtestdataset.tables["main"].newrow(); newrow["name"] = "simon"; newrow["age"] = 23; abbtestdataset.tables["main"].rows.add(newrow); } the datagrid updates no problem, data never committed database. i've searched high , low solution or may missing out on , nothing; @ least i've seen i'm doing right. so missing? undoubtedly stupid. i believe need use dataadapter send updated dataset database. check out links below more info: http://www.java2s.com/tutorial/csharp/0560__ado.net/usedatatabletoinsertarow.htm using ado.net beginners the...
