For example, after I press the button to submit this thread, a new page is created for it. How does this work/what would be the right way to describe it? I'm not sure where this should belong to so apologies if it's in the wrong forum.

Is there a way to have multiple search entries for one TreeView, each for a different column, or having one search entry handle all columns? The effect I'm looking for is (for example) having three columns, and thus typing into three search boxes to narrow down to the results that … |

I have this: typedef struct { int value; } Thing; void doSomething(Thing *ptr) { ptr = (Thing *)calloc(5, sizeof(Thing)); int i; for(i = 0; i < 5; i++) { scanf("%d", (ptr[i]).value); } } int main() { Thing t; doSomething(&t); } Which crashes at the scanf() line. How should I be …

I put a bunch of JButtons in a 2D array into a GridLayout. I want the user to be able to change the size of this grid at run time, but I tried resetting the row/cols, re-adding the buttons, remaking the panel that this grid is in - all to …

I'm just trying to output a value, but whenever it gets to "var max = tb1.value;" it stops working. I can't find out what's wrong with my code. [CODE]<html> <head> <script language="javascript" type="text/javascript"> var tb1 = document.getElementById('textbox1'); function output() { var max = tb1.value; document.write( max ); } </script> <title>asd</title> …

I have a Javascript function that dynamically creates a box with document.getElementById('lightbox').innerHTML. In the box will be, among other things, a div with id="div1" and visibility="hidden" and a form which, onSubmit, calls the function myFunction. The function basically looks like [CODE] myFunction() { document.getElementById('div1').style.visibility = 'visible'; }[/CODE] which has worked …

I have a method that takes in a rectangle shape as a parameter, uses it as a selection box, and finds shapes in an array called shapeObjects that are within the bounds of the selection box. The indexes of those shapes are then added into a new array which is …

Labels would not show up in the output window. The red highlighted code is where said labels get added to the window. I can't tell what's wrong with the code and I've looked at it over and over.

Probably a stupid question, but I need the 'colour' variable for an external class, and it can only return something when it's declared in the constructor. However, the colour returned would then never change. Is there a way to return values from the change listener, or anything else that I …

I've got a NullPointerException at line 50 (and the init on line 12). Can't figure out why.

Is it possible? I want my components to look separated--properly so, with distinguishing border colours, not just with hgaps and vgaps. Is there a way to emulate it? I tried setting a panel background to black, then using hgaps and vgaps in hopes that the black would show through the …

I'm trying to make a method that would create a new tab with a specified name and a white background. However, nothing I pass in (whether it's a JPanel, JButton, etc.) would show up in the final result. I can't tell what's wrong.

The number I'm looking for is valid when it's positive, and nine digits. I used ( (value >= 100000000) && (value <= 999999999) ) first, which worked okay, but did not account for leading zeroes. How do I validate a nine digit number, using only math and no functions, with …

Dumb question, but I've searched everywhere and found nothing specific: is it possible for HSB values to translate directly into a colour (eg. a hue of zero equals red) instead of passing them through an RBG conversion? Also, dumber: I'm not understanding the arrrays people are using, for example [URL="http://www.squarebox.co.uk/users/rolf/download/ColourWheel/ColourWheelApplet.java"]here[/URL] …

I'm supposed to allow the user to draw shapes based on their combobox choices (eg. line, rectangle, circle), colour, fill state, etc. However, nothing is showing up.

I'm supposed to get a 4-digit number from the user, convert it to binary (and hex), then print it out. I have absolutely no idea where to start. I know the algorithm; taking the number, diving it by 2, repeat until the number reaches 0 and the remainders of everything …
