I am trying to get a script like this in AHK but I don't know how to write it in AHK:
string arrow
if (leftArrowKeyPressed) {
arrow = "left"
}
if (rightArrowKeyPressed) {
arrow = "right"
}
if (arrow = "left") {
for (int number = 1000; number < 10000; number++) {
simulateKeyPresses(number)
simulateKeyPresses(mousebutton0)
}
}
I did something similar to this. It uses the While command. Your code might look something like the following:
~left::
While GetKeyState("left", "P") {
Send {NUMBER}
Send {MOUSE_BUTTON}
}
Line 1: '~left::' tells the following lines of code to activate when the left button is pressed. The '~' tells the program to still allow the 'left' arrow key to work. If you wanted this code to run and simultaneously block the 'left' arrow from working, remove the '~'.
Line 2: 'While GetKeyState("left", "P")' is self-explanatory. It's a 'while' loop that runs as long as you are holding the 'left' arrow key.
Line 3 and line 4 are for your code to go. Note that 'NUMBER' can be replace by any number 0-9, and 'MOUSE_BUTTON' can be replaced by either the left mouse button (LButton) or the right mouse button (RButton).
I hoped this helped get you started. Also, as formentioned, the AHK Help manual is very informative. You can search 'AutoHotKey Help' on your computer for your off-line version, or visit this link for the online version. These manuals include documentation of just about anything you could ever hope for, as well as a useful example of code at the bottom of each page.

Does anyone know if there's a way in Visual Studio 2010 with ReSharper 6.1 to comment out the selected lines of code with their closing brackets - or simply to comment out both the highlighted opening bracket and it's corresponding closing bracket? Here's an example of what I mean:
if(something) {
do(this);
}
I am looking for a hot-key so that when if(something) { is selected, it will comment out if(something) { and }, preferably fixing the tabs once commented like so:
// if(something) {
do(this);
//}
This isn't entirely what you're after, but it's pretty close:
Highlight the code inside the if statement by placing the cursor at one brace and hitting Ctrl + Shift + ].
Now hit Ctrl + Shift + Alt + Left Arrow. This will move the code 'left', i.e. outside of the if statement.
You don't need to comment the if statement out after this because it's empty.
Note that you can also move code 'right' to put it back in the if statement later.
I wish to capitalize the first letter of a sentence, on-the-fly, as the user types the text in a CKEditor content instance.
The strategy consists in catching each keystroke and try to replace it when necessary, that is for instance, when the inserted character follows a dot and a space. I'm fine with catching the event, but can't find a way to parse characters surrounding the caret position:
var instance = CKEDITOR.instances.htmlarea
instance.document.getBody().on('keyup', function(event) {
console.log(event);
// Would like to parse here from the event object...
event.data.preventDefault();
});
Any help would be much appreciated including a strategy alternative.
You should use keydown event (close to what you proposed):
var editor = CKEDITOR.instances.editor1;
editor.document.getBody().on('keydown', function(event) {
if (event.data.getKeystroke() === 65 /*a*/ && isFirstLetter()) {
// insert 'A' instead of 'a'
editor.insertText('A');
event.data.preventDefault();
}
});
Now - how should isFirstLetter() look like?
You have to start from editor.getSelection().getRanges() to get caret position.
You're interested only in the first range from the collection.
To extract text content from before the caret use small trick:
move start of the range to the beginning of document: range.setStartAt( editor.document.getBody(), CKEDITOR.POSITION_AFTER_START ),
use CKEDITOR.dom.walker to traverse through DOM tree in source order,
collect text nodes and find out what's before caret (is it /\. $/) - remember that you have to skip inline tags and stop on block tags - hint: return false from guard function to stop traversing.
Example of how you can use walker on range:
var range, walker, node;
range = editor.getSelection().getRanges()[0];
range.setStartAt(editor.document.getBody(), CKEDITOR.POSITION_AFTER_START);
walker = new CKEDITOR.dom.walker(range);
walker.guard = function(node) {
console.log(node);
};
while (node = walker.previous()) {}
And now few sad things.
We assumed that selection is empty when you type - that doesn't have to be true. When selection is not collapsed (empty) then you'll have to manually remove its content before calling insertText. You can use range#deleteContents to do this.
But this is not all - after deleting range's content you have to place caret in correct position - this isn't trivial. Basically you can use range#select (on the range after deleteContents), but in some cases it can place caret in incorrect place - like between paragraphs. Fixing this is... is not doable without deeeeeeeep knowledge about HTML+editables+insertions+other things :).
This solution is not complete - you have to handle paste event, deleting content (one can delete words from the start of sentence), etc, etc.
I guess there are couple of other problems I didn't even thought about :P.
So this approach isn't realistic. If you still want to implement this feature I think that you should set timer and by traversing DOM (you can use walker on range containing entire document, or recently typed text (hard to find out where it is)) find all sentences starting from lower letter and fix them.
This is what worked for me in Ckeditor 4.
var editor = CKEDITOR.instances.editor1;
editor.document.getBody().on('keydown', function(event) {
if (event.data.getKeystroke() >= 65 && event.data.getKeystroke()<=91 && encodeURI(this.getText())=="%0A" && this.getText().length==1 ) {
//uppercase the char
editor.insertText(String.fromCharCode(event.data.getKeystroke()));
event.data.preventDefault();
}
});
OK let me explain my problem.
I'm working on a program where I have a button. Clicking it causes the number "1" to appear, then, after that, any further clicks will increment that value until it reaches the value of "9". (It's a string). I wrote this code which declares an int variable to 0 (Yes, this was a mistake but let me continue) then increment it and parse it to string and show it on the button text(This is the code that executes on button click):
private: System::Void a0_Click(System::Object^ sender, System::EventArgs^ e) {
int i = 0;
i++;
a0->Text = i.ToString();
}
However, as you can suspect, I did the foolishness of declaring i with 0 for each button press, so the result was that 1 was the only value showing on the button. The next thing I tried doing, was declaring i as global variable with the value of 0. However, I came to another problem. I have 82 buttons of that kind, and I'm going for the easiest sollution I can find, so sharing the i variable seemed logical,
The next problem was that if I pressed 5 times the first button, the number displayed on it would be "5" however if I pressed another button, the value wouldn't be "1" by default, it would be "6" (The value of the first button incremented by one). Basically it would inherit the value of the first.
Now I'm at a dead end. I have no idea what to do. I tried using i and i2 but I was just chasing my own tail. Is there a very easy solution to this? Keep in mind I've got 82 buttons (Yes I know it's alot) which are by default 0. When I click each one I need it to increment by one, starting from 0. Any ideas?
Notes: OS is Windows XP, IDE is Visual Studio 2010m using windows forms app, C++/CLI. If I forgot to mention anything post in comments and I'll add it.
You can inspect sender to find out what button was clicked.
void anybutton_Click(System::Object^ sender, System::EventArgs^)
{
Button^ btn = dynamic_cast<Button^>(sender); // or safe_cast
int i;
if (System::Int32::TryParse(btn->Text, i)) {
i++;
btn->Text = i.ToString();
}
}
I'm using the following command to print a justified text:
^FB1800,3,0,J^FT100,200^A0B,26,26^FH\^FDLONG TEXT TO BE PRINTED, WHICH DOESNT FIT IN ONLY 3 LINES...^FS
The command ^FB1800,3,0,J prints a field block in a width of 1800 dots, maximum 3 lines, justified.
The problem is that if the text exceeds the maximum number of lines, it overwrites the last line! :( That of course makes the text of the last line unreadable.
How can I avoid that? Does anybody know if is there a way to cut the exceeding text?
The documentation says exactly that this happens:
Text exceeding the maximum number of lines overwrites the last line. Changing the font size automatically increases or decreases the size of the block.
For reference: I'm using printer Zebra 220Xi4.
Any help would be appreciated. Thank you!
Take a look at the ^TB command. It is preferred over the ^FB command and truncates if the text exceeds the size defined in the TB params
I had just about the same problem, what fixed it in my case - although not the most elegant way - is to specify a higher number of maximum lines, and then formatting it in a way that only the first 3 are in the visible area.
In your case it would be for example ^FB1800,7,0,J instead of ^FB1800,3,0,J
This at least fixed it for me right away, because I print this text at the bottom of the label. If you need to have it somewhere in the middle or top, there might be some tricks with putting a (white) box on top of the overflow-area, since the Zebra printers seem to render before printing. Hope it helps.
Depending on the higher-level programming language you're using (assuming that you are), you could accomplish the same thing (truncate the text to be printed to a specified number of characters) with code like this (C# shown here):
public void PrintLabel(string price, string description, string barcode)
{
const int MAX_CAPS_DESC_LEN = 21;
const int MAX_LOWERCASE_DESC_LEN = 32;
try
{
bool descAllUpper = HHSUtils.IsAllUpper(description);
if (descAllUpper)
{
if (description.Length > MAX_CAPS_DESC_LEN)
{
description = description.Substring(0, MAX_CAPS_DESC_LEN);
}
}
else // not all upper
{
if (description.Length > MAX_LOWERCASE_DESC_LEN)
{
description = description.Substring(0, MAX_LOWERCASE_DESC_LEN);
}
}
. . .
This is what I'm using; is there any reason to prefer the "raw" ^TB command over this?
For me, Visual Studio's Ctrl + K, Ctrl + C keyboard shortcut is used to comment-out the selected lines. When editing C++, this sometimes uses block comments (/* */) and sometimes uses line comments (//). Why does it change? How does it decide which to use when?
A couple other discussions on the topic:
Visual studio feature - commenting code Ctrl K - Ctrl C
visual studio C++ toggle comment ? comment while not whole line is selected?
Based on my own tinkerings, and what was said in those articles...
It's based on the start/end of the selection. It seems to use double slashes // whenever you start your selection at the beginning of the line AND end it at the end of a line.
It will use /* */ notation whenever the selection occurs midway through lines.
IE:
If I have the code
int main () {
return 0;
}
and highlight only int main, it will convert it to /*int main*/.
If I highlight the entire code section, starting after the indent tab, it will convert it to
/*int main () {
return 0;
}*/
But if I highlight the section starting before the indent tab, it converts it to
//int main () {
// return 0;
//}

Selecting entire lines (including leading whitespace) will use //
Selecting at least one partial line
If a // comment is included, will use //
Otherwise, will use /* */
