Selection without limits of the selection
I use CS2 so I can't call on the limits of selection (which seems to be the preferred method of working with playlists)
var activeDocument.selection.bounds = SB;
var sbWidth = sb [2] - sb [0];
var sbHeight = sb [3] - sb [1];
Alert (sbWidth + "," + sbHeight)
If the code above does not work for me
How will I know (1) If a selection is set (selection width & height = 0?) and (2) find the width and height of the selection said, assuming that only the rectangle is used (no ellipse or lasso).
See you soon
Here are a couple of x functions that work with CS2...
function hasSelection (doc) {
if(doc == undefined) doc = activeDocument;
var res = false;
var as = doc.activeHistoryState;
doc.selection.deselect();
if (as != doc.activeHistoryState) {
res = true;
doc.activeHistoryState = as;
}
return res;
};
getSelectionBounds = function(doc) {
if(doc == undefined) doc = activeDocument;
var l = doc.artLayers.add();
doc.selection.fill(app.foregroundColor);
var bnds = l.bounds;
var hs = doc.historyStates;
if (hs[hs.length-2].name == "Layer Order") {
doc.activeHistoryState = hs[hs.length-4];
} else {
doc.activeHistoryState = hs[hs.length-3];
}
for (var i = 0; i < bnds.length; i++) {
bnds[i] = bnds[i].value;
}
return bnds;
}

Windows Photo Gallery. How can I change the settings in the Windows Photo Gallery to automatically open the image without going to the index first?
Additional information: there are 2 computers that I use on the first Gallery Photo of Windows will open the image and allow me to use the left and right buttons to scroll through the rest of the photos in the folder, that's what I want.
On the 2nd computer when I open an image it will open the Windows Photo Gallery in an index with thumbnails of the displayed record. How can I change so that it opens the same thing as the first computer?
I did the following on both computers; Right-click on the image and select open with...--> choose the default program--> go--> Program Files, Windows Photo Gallery, but it will be open always differently on computer 2.
Both computers use Windows Vista 32-bit.
Thanks in advance.
Australian salvation,
This would happen if the file associations are corrupted on the computer, try method to set Photo Gallery Windows as the default program for opening files jpeg or png below image types.
(a) open default programs by clicking the Start button, click default programs.
(b) click on associate a type of file or Protocol with a program
(c) in the following list of file protocol search jpeg and make sure that you have associated with the program that uses it and then check if it works.
Change the programs that Windows uses by default

I can install Windows 7 without initially providing the product key?
Peut I install Windows 7 without initially provide the product key during installation? I'd rather go once the installation is finished, I just have to copy and paste it in the email like that.Hello
Yes, you can try a free key of Windows 7 Installation. But be sure that you enter the product key to activate Windows wihtin 30 days grace period. Once the 30 days grace period end your system will go in any safe and you may need to reinstall the copy again.
Unlike Windows Vista, if you si vous achetez buy Windows 7 DVD you get specified edition disk and installation you will not get an option to select the edition. Almost to the last step of the Installation, you will get the opportunity to enter the product key that you can jump and try to enter the product at the time of the Activation key.

I use Lr5 on a PC, working on the Nikon RAW files. Without even touching the images, they lose their shine after a few seconds. Why and how can I keep the liveliness to the origin?
Step 1: Adjust an image in Lightroom, until you are satisfied with its appearance
Step 2: Use develop-> new preset, select all selections in the new preset dialog box (note: I always uncheck the exhibition here, who should probably be adjusted picture, I'm mostly interested by contrast, vibrance and camera calibration settings)
Step 3: In the import dialog box, on the right, under appliquer apply when importing, select the preset desired beside development parameters

Update without waiting in the update and delete command.
Dear all,
My database is GR 11, 2 on Linux.
What is the best way to resolve the line lock if 2 different sessions commands delete records from the same table?
Can we use to update without waiting in the Update or Delete command?
Thank you
ImranWhat you can do too, is that you can perform the update that you did for the update with select... see the following topics
declare
cursor c1 is
Select * from EMP
where deptno = 20
Update;
Start
for c1_rec looping c1
Update emp
Set sal = 11

How to move the ends of the lines slanted towards the limits of the purge
Hi all
I developed a script that deletes the page elements to the purge. To achieve this, that I collect all the elements of the page (with the exception of text blocks) located partially on the editing table, create a temporary mask and 'trim' with subtraction of Pathfinder function. However, this approach does not work with graphic lines so I'm trying to move the ends of the lines to the limits of the substantive area lost. (I guess these are simple straight lines consisting of two end points).
I knew how to deal with orthogonal lines - it's pretty easy:
if (theItem.constructor.name == "GraphicLine" && theItem.paths.length === 1) { path = theItem.paths[0]; if (path.pathPoints.length === 2) { ep = path.entirePath; w = ep[1][0]-ep[0][0]; h = ep[1][1]-ep[0 ][1]; if (w > h) { newEp = [ [ spreadWithBleedBounds[1], ep[0][1] ], [ spreadWithBleedBounds[3], ep[1][1] ] ]; path.entirePath = newEp; } else if (h > w) { newEp = [ [ ep[0][0], spreadWithBleedBounds[0] ], [ ep[1][0], spreadWithBleedBounds[2] ] ]; path.entirePath = newEp; } } }This moves A1 - A2, B1 , B2, C1 , C2, D1 to D2.
But how to treat skewed lines? How to calculate the coordinates of the point E2 and F2? Y at - it a magic formula? Or can someone point me to the right direction: for example a book to read?
I assume this has something to do with geometry/trigonometry, but I haven't studied this kind of things at school. (I graduated from an art school - designed to draw naked models instead).
If someone will answer my question, please do it on basic level since I'm a total noob in the present.

Hi Kasyan!
I was not trying to integrate this into your script, so you may need to adjust a little. The trick is to define a function that detects the point of intersection of two lines - and, of course, you must call it for lines that will not fail to cross the border of the page! (Otherwise, it would simply expand * any * the line upward and on the border.)
I think it would be wise to predict a small mistake for lines that seem to run "up to" the edge of the page - I tested a line for 'x '.<= 0"="" on="" a="" line="" that="" appeared="" to="" start="" on="" 0;="" the="" control="" panel="" told="" me="" so.="" however,="" i="" didn't="" type="" that="" 0="" in;="" i="" dragged="" the="" line="" to="" the="" edge.="" apparently,="" it="" was="" *not*="" at="" precisely="" "0mm",="" but="" something="" like="" "0.001mm",="" because="" the="" script="" simply="" didn't="" "see"="" the="">
My function comes from this page: http://local.wasp.uwa.edu.au/~pbourke/geometry/lineline2d/ and I did not test it does of orthogonal lines
(but of course, you could add this in exceptional cases), and it's my script extending the line, with a small wrapper to configure things.
The function tests * any * tail against * any * other line, so if we meet the page bounding box, I get the intersection with the purge of the side area where it crosses the bbox page.
line = app.selection[0]; // pg size in "regular" [y1,x1, y2,x2] format pagebbox = [0,0, app.activeDocument.documentPreferences.pageHeight,app.activeDocument.documentPreferences.pageWidth ]; bleedDist = 5; // bleedbbox = [ pagebbox[0] - bleedDist, pagebbox[1] - bleedDist, pagebbox[2] + bleedDist, pagebbox[3] + bleedDist ]; pt1 = line.paths[0].pathPoints[0].anchor; pt2 = line.paths[0].pathPoints.lastItem().anchor; // Start point: if (pt1[0] <= pagebbox[1] || pt1[0] >= pagebbox[3] || pt1[1] <= pagebbox[0] || pt1[1] >= pagebbox[2]) { if (pt1[0] <= pagebbox[1]) intersectPt = IntersectionPt ( [pt1, pt2], [ [ bleedbbox[1], bleedbbox[0]], [bleedbbox[1], bleedbbox[2] ] ] ); if (pt1[0] >= pagebbox[3]) intersectPt = IntersectionPt ( [pt1, pt2], [ [ bleedbbox[3], bleedbbox[0]], [bleedbbox[3], bleedbbox[2] ] ] ); if (pt1[1] <= pagebbox[0]) intersectPt = IntersectionPt ( [pt1, pt2], [ [ bleedbbox[1], bleedbbox[0]], [bleedbbox[3], bleedbbox[0] ] ] ); if (pt1[1] >= pagebbox[2]) intersectPt = IntersectionPt ( [pt1, pt2], [ [ bleedbbox[1], bleedbbox[2]], [bleedbbox[3], bleedbbox[2] ] ] ); line.paths[0].pathPoints[0].anchor = intersectPt; } // End point: if (pt2[0] <= pagebbox[1] || pt2[0] >= pagebbox[3] || pt2[1] <= pagebbox[0] || pt2[1] >= pagebbox[2]) { if (pt2[0] <= pagebbox[1]) intersectPt = IntersectionPt ( [pt1, pt2], [ [ bleedbbox[1], bleedbbox[0]], [bleedbbox[1], bleedbbox[2] ] ] ); if (pt2[0] >= pagebbox[3]) intersectPt = IntersectionPt ( [pt1, pt2], [ [ bleedbbox[3], bleedbbox[0]], [bleedbbox[3], bleedbbox[2] ] ] ); if (pt2[1] <= pagebbox[0]) intersectPt = IntersectionPt ( [pt1, pt2], [ [ bleedbbox[1], bleedbbox[0]], [bleedbbox[3], bleedbbox[0] ] ] ); if (pt2[1] >= pagebbox[2]) intersectPt = IntersectionPt ( [pt1, pt2], [ [ bleedbbox[1], bleedbbox[2]], [bleedbbox[3], bleedbbox[2] ] ] ); line.paths[0].pathPoints.lastItem().anchor = intersectPt; } function IntersectionPt (ln1, ln2) { var ua; var x1 = ln1[0][0], x2 = ln1[1][0], x3 = ln2[0][0], x4 = ln2[1][0]; var y1 = ln1[0][1], y2 = ln1[1][1], y3 = ln2[0][1], y4 = ln2[1][1]; ua = ((x4 - x3)*(y1 - y3) - (y4 - y3)*(x1 - x3))/((y4 - y3)*(x2 - x1) - (x4 - x3)*(y2 - y1)); return [ x1 + ua*(x2-x1), y1 + ua*(y2-y1) ]; }

I just assigned a manual static IP on my WiFi printer and reserved in the DHCP reservation Board. Which works very well. The problem is, ALL the devices listed in this table, take the name of the device that is reserved, after you save the settings.
