问题 OK, the umpteenth conditional column question: I'm writing a stored proc that takes an input parameter that's mapped to one of several flag columns. What's the best way to filter on the requested column? I'm currently on SQL2000, but about to move to SQL2008, so I'll take a contemporary solution if one's available. The table queried in the sproc looks like ID ... fooFlag barFlag bazFlag quuxFlag -- ------- ------- ------- -------- 01 1 0 0 1 02 0 1 0 0 03 0 0 1 1 04 1 0 0 0 and I want to do

问题 I've got a ToggleButton that's set up like: final ToggleButton filterButton = (ToggleButton) findViewById(R.id.filterTags); filterButton.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { if (filterButton.isChecked()) { // pop up the list of tags so the user can choose which to filter by // once one is chosen, the spinner will be updated appropriately showDialog(DIALOG_TAGS); } else { // going unpressed, set the the spinner list to everything updateSpinner(db

问题 Currently I have two arrays, one is a list of numbers titled nums, and the ms is a list of strings titled places. Ex. nums=[1,2,3,4,5] places = ["house","gym", "work", "school", "park"] both arrays are the same length. I want to make a bar chart with these arrays that looks similar to http://bl.ocks.org/mbostock/3885304, but the data is coming from these arrays rather than a tsv file. In Bostock's code the data is read in from a tsv file, the code is below. d3.tsv("data.tsv", type, function

问题 I have this upsert function that allows me to modify the fill_rate column of a row. CREATE FUNCTION upsert_fillrate_alarming(integer, boolean) RETURNS VOID AS ' DECLARE num ALIAS FOR $1; dat ALIAS FOR $2; BEGIN LOOP -- First try to update. UPDATE alarming SET fill_rate = dat WHERE equipid = num; IF FOUND THEN RETURN; END IF; -- Since its not there we try to insert the key -- Notice if we had a concurent key insertion we would error BEGIN INSERT INTO alarming (equipid, fill_rate) VALUES (num,

问题 Hallo, my team and I are about to start a project, and we would really like to use ASP.NET MVC, not the Web Forms. Why? Nothing special, just we want to learn it well and to measure what would be better to use in future projects. But, our project has important request. We need ability to dynamically load user controls, that can be created and uploaded in runtime. With ASP.NET Web Forms and it's LoadControl method it's simple. Can we do something like that with MVC? Tnx 回答1: Partial views are

问题 I am currently writing a Programm using VBA, which opens particular excel files from the folder C:Reports. I Need to be able to open the file dynamically from user input in this folder such as; 1)User gets an Dialog box and sees the first question "What is the Name of the file" where he/she has to type the Filename without seeing the folder of the file.

问题 I have a relatively simple question here. What I require is this; I need to have a page with 5 buttons at the top and a DIV beneath them (initially hidden). When a button is clicked, it loads content into the DIV (in the form of another DIV) eg. [Button 1] [Button 2] [Button 3] [Button 4] [Button 5] //5 buttons or links <div id="content"> // area for content to be loaded </div> <div id="content1"> //could be a table or image </div> <div id="content2"> //could be a table or image </div> <div

问题 I am making software that will need to dynamically create java bytecode, and possibly even make it a runnable jar. My current idea is to create a new .java file and compile it at runtime. I can create the file, but I'm not sure how to compile it at runtime, and make it a runnable jar. Any help would be greatly appreciated. public static String generate(String filePath) { try { File file = new File("Test.java"); if(!file.exists())file.createNewFile(); FileWriter write = new FileWriter(filePath
