freeze

How can i freeze initial 2 -3 leftmost column in asp.net grid view? so that while horizontal scrolling initial 2 - 3 columns that got freezes will always be display. Any answers?? Yes, it seems to be possible with some css magic, with the pinned and scrollable columns on different z-indexes to keep the pinned on top. This comes with the caveat that overflow:scroll may not be 100% portable (I've tested on IE 8/9 and Chrome FWIW). Take a look at this jsFiddle here The ASPX I used to generate the GridView is below. Note the css classes pinned and scrollable for fixed and scrolling columns

Object.freeze() 方法可以 冻结 一个对象。一个被冻结的对象再也不能被修改；冻结了一个对象则不能向这个对象添加新的属性，不能删除已有属性，不能修改该对象已有属性的可枚举性、可配置性、可写性，以及不能修改已有属性的值。此外，冻结一个对象后该对象的原型也不能被修改。 freeze() 返回和传入的参数相同的对象。 const obj = { prop: 42 }; Object.freeze(obj); obj.prop = 33; // Throws an error in strict mode console.log(obj.prop); // expected output: 42 同样可以冻结数组 let a = [0]; Object.freeze(a); // 现在数组不能被修改了. a[0]=1; // fails silently a.push(2); // fails silently 冻结对象只是进行了“浅冻结” obj1 = { internal: {} }; Object.freeze(obj1); obj1.internal.a = 'aValue'; obj1.internal.a // 'aValue' 实现深冻结需要使用递归进行操作 function deepFreeze(obj) { // 取回定义在obj上的属性名 var

I'm trying to create a JavaFX program, which is working - but I am trying to get a progress bar to update whilst it is running. However, the program just seems to freeze and locks up until it has finished processing. Does anyone have an idea of how I can get the program not to freeze whilst running - and to get the progress bar to update whilst it processes? Thanks You can put the progressbar progress in a Platform.runLater(()-> progressBar.setProgress(progressValue)); so it will be executed at a later point in time. 来源： https://stackoverflow.com/questions/28941347/javafx-program-locks-freezes

I have a UIDatePicker inside a UIScrollView. But the UIDatePicker does not respond to scroll touches. It's the scrollview that is scrolling. Reading some docs on the net, I've set "Delay Content Touches" to NO, an now I see the datepicker starting a slight scroll, but it's still the scrollview that take the final word. I have some place on the screen where the user can touch to scroll the view. So how may I separate the two kind of scrolls ans make the datepicker scroll in a normal way ? Thank you for your help Solved using that post : http://www.alexc.me/uiscrollview-and-uidatepicker/153/

I am trying to use cx-freeze to create a static self-contained distribution of my app (The Spye Python Engine, www.spye.dk ), however, when I run cx-freeze, it says: Missing modules: ? _md5 imported from hashlib ? _scproxy imported from urllib ? _sha imported from hashlib ? _sha256 imported from hashlib ? _sha512 imported from hashlib ? _subprocess imported from subprocess ? configparser imported from apport.fileutils ? usercustomize imported from site This is my setup.py: #!/usr/bin/env python from cx_Freeze import setup, Executable includes = ["hashlib", "urllib", "subprocess", "fileutils",

I have an embedded board with a kernel module of thousands of lines which freeze on random and complexe use case with random time. What are the solution for me to try to debug it ? I have already try magic System Request but it does not work. I guess that the explanation is that I am in a loop or a deadlock in a code where hardware interrupt is disable ? Thanks, Eva. Typically, embedded boards have a watch dog . You should enable this timer and use the watchdog user process to kick the watch dog hard ware. Use nice on the watchdog process so that higher priority tasks must relinquish the CPU.
