问题 Currently I have a UITextField in a custom cell and I want to get the Y coordinate of that UITextField on the level of the View Controller's view (UIView). Currently I am trying to do something like this: if (thetextField.superview.superview.superview.frame.origin.y >= keyboardY) { } But it seems that the Y coordinate is always 0 when it is in fact not. Is there any way to achieve this? I am doing this because I want to detect whether the UIKeyboard is blocking the UITextField on the UIView

问题 I had previously asked a question on this issue, to which you guys supplied fantastic answers. I since "discovered" the intoxicating power of contextual styling (http://www.w3.org/TR/css3-selectors/#selectors) -- thanks once again to you all -- and now I am hooked. I've made good progress on applying contextual styling to my current design here: http://jsfiddle.net/gFA4p/200/ I've run into a few issues, though.

问题 I have a dynamic table that I generate after getting some inputs from the user to present some tabular data. I need to know if there is away to assign a fixed height for the cells even if some of them have some content / text. I would like all the cells to have 30px height regardless if they have content or if they are empty. This is the CSS I have: table { width: 90%; height:100%; } table th, table td { border: 1px solid gray; height:30px !important; padding: 9px !important; width: 16%; }

问题 I would like to read a (fairly big) log file into a MATLAB string cell in one step. I have used the usual: s={}; fid = fopen('test.txt'); tline = fgetl(fid); while ischar(tline) s=[s;tline]; tline = fgetl(fid); end but this is just slow. I have found that fid = fopen('test.txt'); x=fread(fid,'*char'); is way faster, but I get a nx1 char matrix, x . I could try and convert x to a string cell, but then I get into char encoding hell; line delimiter seems to be \n\r, or 10 and 56 in ASCII (I've

Is it possible to delete entries from Column A if they also appear in Column B? In other words, I want to 'dovetail' two columns so that no entry is represented in both columns. 回答1: You can use ADO for database-type actions, for example: Dim cn As Object Dim rs As Object Dim strFile As String Dim strCon As String Dim strSQL As String Dim i As Integer
