Utilities Progress Bar Operations that take more than a split second indicate their progress with a progress bar and in the title bar of the widget’s window. There are three mechanisms for implementing this. Context handlers The recommended and the simplest approach is to wrap the code into context handler progressBar . If the operation consists of a known number of steps that take similar time, the context handler can be used as follows: with self.progressBar(n_steps) as progress: for k in range(n_steps): self.do_some_processing() progress.advance() In general, the argument of self

Excel password removal

陌路散爱 提交于 2020-03-03 10:32:06
问题 We receive Excel workbook files every day which are password protected with the same password. We know this password. Is there a utility or method to remove password protection on these workbook files without invoking Excel.exe or the Excel object. Our goal is to take Excel out of the process and utilize SpreadsheetGear in VB.net. However, SpreadsheetGear can only unprotect worksheets not workbooks. Thanks 回答1: Are they XLS or XLSX files? for XLSX apparently you can use the RMS SDK to work

convert a `find` like output to a `tree` like output

余生长醉 提交于 2019-12-23 15:23:11
问题 This question is a generalized version of the Output of ZipArchive() in tree format question. Just before I am wasting time on writing this (*nix command line) utility, it will be a good idea to find out if someone already wrote it. I would like a utility that will get as its' standard input a list such as the one returned by find(1) and will output something similar to the one by tree(1) E.g.: Input: /fruit/apple/green /fruit/apple/red /fruit/apple/yellow /fruit/banana/green /fruit/banana

Get index of array of objects via jquery

倖福魔咒の 提交于 2019-12-19 04:25:46
问题 I have the following array: var = array[ {"id" : "aa", "description" : "some description"}, {"id" : "bb", "description" : "some more description"}, {"id" : "cc", "description" : "a lot of description"}] and I try to find the index of the array that contains the id === "bb" . The solution I came up with is the following: var i = 0; while(array[i].id != "bb"){ i++; } alert(i) //returns 1 Is there an easier way that has cross-browser functionality? I tried $.inArray(id,array) but it doesn't work

Batch file Mixing multiple colors

帅比萌擦擦* 提交于 2019-12-13 09:24:20
问题 I've been wondering if someone have made a batch file utility that can mix 2 batch colors into another color (for example: Red + Yellow to make Orange). I don't really know if its even possible or not to do such a thing, but if there is, I want to know. 回答1: Well, if with "batch colors" you refer to color values of color command, then it is very easy to get some equivalences based on the original color table shown by color /? command: 0 = Black 8 = Gray 1 = Blue 9 = Light blue 2 = Green A =
