问题 I have a collectionView and allow a user to dynamically add cells to the collectionView. The view controller only shows one cell at a time and I want the first textView (which is part of the cell) to become the firstResponder (and keep the keyboard visible at all times), which works fine when loading the view controller (as well as in one of the cases below). I have created a method to detect the current cell, which I call every time in any of these cases: (1) user scrolls from one cell to

问题 I am currently doing a loop from a DataGridView that will read each selected item and create a cell with the item's barcode in it (cells to be exported depends on the quantity the user had input), but If I tried to export 1 barcode label (1 pdfCell) it wouldn't export and says 'the pdfTable is empty' because I have a pdfTable.Columns(5) which is means that my table has a column count of 5. So as long as I try to export cell quantities that are not divisible by 5 it wouldn't export. Example 1:

阅读更多关于 excel vba adding and subtracting values in different cells

问题 I am working on a kind of scheduling sheet in Excel. In this sheet man days for certain experts and activities are entered. It often occurs that man days have to be shifted between experts and activities. The part I am stuck with is the actual updating of values in the cells. The idea is that all the lines in my first array represent row numbers. I step through each cell in the range look for a value and subtract the shifting days. If the shifting days are greater than the cell value I move

阅读更多关于 How to sum the values of an MxN cell array?

问题 How can I make the sum of values in an MxN cell array? I used cellfun('sum',CellArray{i}) in which, i refers to the MxN index of the CellArray .

What's the right way to do that please? 回答1: I don't know if I got your problem entirely right. You just want the total sum of all elements of a cell array? Assuming they are doubles, you first need to transform your cell array into a matrix, and
