I made this program were the user can type in a year between 2009 and 2011 and get snow depth and air temperature data for the chosen year displayed on a graph. I have one xls file for the temperature for each day from day 1 to day 365. I also have another xls file for snow depth from day 1 to day 212. So some days they didn't bother to measure snow depth because it was summer anyways. Between 30. april to 1. october they didn't measure snow depth. I want to add 153 zeroes with code between 30. april and 1. oct so it adds up to 365 days. day 121 = 30. april Download Air temp xls: https://dl

Confusing add command in x86 assembly

为君一笑 提交于 2019-12-02 13:20:00
I was looking through some code and found 2 lines that perplexed me: add -0x4(%esi,%ebx,4),%eax cmp %eax,(%esi,%ebx,4) I am accustomed to the standard add src,dst and cmp x1,x2 and I'm not really sure what these lines are actually doing. I believe that it is compiled with GCC That's using the Base + (Index * Scale) + Displacement addressing mode. At least, I think so. I'm not real familiar with the AT&T syntax. I think the Intel syntax would be: add eax,[esi + ebx*4 - 4] cmp [esi + ebx*4],eax This looks like it's indexing into an array of integers (4-byte values). Imagine in C that you want to

Adding a second table in a database

自作多情 提交于 2019-12-02 12:51:13
This is my first post! I hope you can help me out! :-) I used the code provided by the NotePadExample from the developers doc to create a database. Now I want to add a second table to store different data. I can add notes without a problem, and the notes table is created in a similar way as my routes table is. I simply "copied" and edited the given code, but when I try to insert into the new table I get an error saying: "0ERROR/Database(370): android.database.sqlite.SQLiteException: no such table: routes: , while compiling: INSERT INTO routes(line, arrival, duration, start) VALUES(?, ?, ?, ?);

Add Object to JPanel after button click

扶醉桌前 提交于 2019-12-02 11:34:09
问题 I have created a JScrollPane with a JPanel inside it and I want to add JPanel/JLabel/Other objects after pressing the button. For example after three button presses I want to get something like this: I tried myJPane.add(testLabel) with testlabel.setBounds() but no result, I don't want to use GridLayout because of the unchangeable sizes. I would like it if the added objects had different sizes - adjusted to the text content. What should I use for it and how? Thanks in advance. Best regards,
