Without RegEx how?

find multiple instances of a string, for example the word 'src' inside another string.

using IndexOf I can find the first occurrence of 'src' and use substrings, as suggested by me simon in another thread, closely related to this.

But this forces me to find several instances of a string within a larger string and insert substrings in an efficient manner, without RegEx features.

Clues?

I can make it through if statements and that work my way towards the end of the string, but that seems a lot more code it should be necessary.

Instead of getting this RegEx program that has been proposed, I found this perfect alternative.

public static String replace(String _text, String _searchStr, String _replacementStr)
    {
        //String buffer to store str
        StringBuffer sb = new StringBuffer();
        // Search for search
        int searchStringPos = _text.indexOf(_searchStr);
        int startPos = 0;
        int searchStringLength = _searchStr.length();
        // Iterate to add string
        while (searchStringPos != -1)
        {
        sb.append(_text.substring(startPos, searchStringPos)).append(_replacementStr);
        startPos = searchStringPos + searchStringLength;
        searchStringPos = _text.indexOf(_searchStr, startPos);
        }
        // Create string
        sb.append(_text.substring(startPos,_text.length()));
        return sb.toString();
    }

So there go.

App without head: how to check the status

1. I read this on the BB site:

Criticism	Process that must be running at all times (for example, system processes)
In the foreground	Processes that are running in the foreground
Background	Processes that run in the background
Stop	Process involved in RAM without running

The question is can we write the code to check the States of the app to trigger certain activities?

I also want to know the other possible States of the life cycle such as: "application started", "closed app"...

A problem critical of the app without head is memory management, and we can only until BB have a better explanation on the life cycle of the app without a head.

2. for an application in the short-term, event after 20 years, the app is still listed on memory and CPU usage. That seems abnormal, because I guess that after 20 years, the application will be stopped and not be able to use the memory and CPU more.

Can someone explain?

Thank you very much!

Would you like to take a look at this app, I wrote that has a component without head and uses QLocalSocket to communicate between the headless and the (https://github.com/blackberry/Cascades-Community-Samples/tree/master/wakemebybeacon) user interface process. There is also a blog explaining how it works here: http://devblog.blackberry.com/2014/07/wake-my-beacon/.

You can detect changes in status of process on the part without head like this (https://github.com/blackberry/Cascades-Community-Samples/blob/master/wakemebybeacon/WakeMeByBeaconSe...) and manipulate them like this (https://github.com/blackberry/Cascades-Community-Samples/blob/master/wakemebybeacon/WakeMeByBeaconSe...).

When a component without a head (process) is distributed will be passable for 20 seconds, after which it is moved to a queue where it receives no processor, but can be awakened (marked as executable) of certain classes of events. While stopped the headless process always retains a memory footprint, but is not available.

File to restore data without backup - how it works?
Hello

I have a 10.2 database runs on Linux without a recovery catalog archivelog mode.
I created backup current controlfile.
Then, I created tablespace 'data' and a table with a few lines inside.
Then I deleted all the controlfiles and the data file from the tablespace 'data '.
I did the restore and recovery:
RMAN > restore controlfile from autobackupp
RMAN > restore data from the tablespace.
creating data fno = 6 name file = /...
restore not made; all files readonly, offline, or already restored

RMAN > restore database;
(...)

It's good, but I wonder how it works: I've restored a backup controlfile and does not know this controlfile tablespace 'data '. I have no current controlfiles (they were all lost), so there is no RMAN Repository.
Can someone explain this to me?

Thanks in advance,
Sousou
Sousou,

There is a complete recovery (which means your controlfile is up-to-date, and you get so far) and incomplete recovery.

If you do not issue
until the logseq | Yvert | date
Before you restore and recover
RMAN will review the latest situation.
In this situation, there is no data of tablespace, RMAN is unnecessary restore this tablespace.
Restore the controlfile doesn't help here, such as structural changes in the database result in an automatic backup of the controlfile.
You restore the most recent backup, so in this automatic backup tablespace has also disappeared.

If I choose a parameter to the control center and later wish to return to "default" of security, how this is done? I'm afraid without knowing how by default.

Could someone help me please? When in a Gmail message I clicked on 'Follow an element', Firefox has sent msg prevent that. If I had to choose a control center security setting to allow 'follow an element", but LATER wanted to default or go back to the Firefox command as it was, is - it possible? It is quite something to worry about to TAKE A LEAP (select a setting) not knowing how to go back. Yours truly, Amanda2.

Without Illustrator, how can I set a custom EPS or SVG shape

I have a vector shape to SVG. I need to turn it into a custom Photoshop shape.
How can I do this directly or load it into Photoshop as a path.
I do not have and cannot have access to Illustrator.

An acceptable solution for svg files, apart from using illustrator, would be a program called Gimp.

https://www.GIMP.org/

You can open the svg file in Gimp and import the paths, and then file > export in tiff format and at the beginning of the tiff in photoshop, paths should be kept.

Eps files, you could use Inkscape to open the eps file, then file > save as > Inkscape svg, which can be open in Gimp with the pat (s) and then saved to TIFF for photoshop.

https://Inkscape.org/en/

Both programs are open source and free.

Pure install mac without disabling, how to activate it again?

Dear all,
Today, I installed a clean version of Mac OS. I did not remove the creative cloud, or the installed application, and or disconnected / deactivated my account.
On my macbook evrything works fine, but I'm not able to install photoshop etc. in normal mode on my mac.
How can I solve this problem? Other recording cloud-based software offers a portal in which you can disable installed previous. Does Adobe offer something like that?
I appreciate your help,
Yours sincerely,

SWF swfLoader without unload - how to solve?

Hi, my SWFs unload properly when I run the application in the environment of Flashbuilder, but in the release on the web, they are not I wonder if I need test the SWF unload until I close the box of custom contextual menu?
I load the SWF files like this within a context menu custom titleWindow:
protected

function textarea1_clickHandler(event:MouseEvent):Sub
{
this .move (1,1);
Loader.Load)
"lessons/EBS_new_FieldOps_MileStone6.swf" );
}
-------------------------------------------------------------------------------------
I unload SWFs like this:
protected

function titlewindow1_closeHandler(event:CloseEvent):
Sub
{
loader.unloadAndStop ();
PopUpManager.removePopUp)
ce );
}
-------------------------------------------------------------------------------------
The popup window disappears, but the film remains loaded.

How do you know the movie unloaded in the debugger? Have you seen the

in the console? If this is not the case, there can be no discharge completely.

If I don't have that one window without tab, how can I remove the label of the tab at the top of the window?

OK, I open a window on my home page. In the upper left part of the window, I have the Firefox icon and next to it the name of the page that I am. Below that is the menu bar which I use enough to leave it there. And now, with no other tabs open, is a bunch of lable/tab tab / be it with the icon of Firefox and next to him, the name of the page, I'm on. Below that is the url/address bar which usually also shows the name of the page that I am.

I like a clean screen with small footprint as possible. Usually, I know which window to page / I'm on because I'm the one who got me here. I have need a band to additional tabs for a window that has no open tabs take more space and tell me what I already know.

If I could drop the icon of Firefox waste than any of the top of my screen that would be great, but I'm sure that's not an option.

If I could put this menu bar on the same line as the address bar, I'd be in heaven to the space used effectively! But I'm also sure that that won't happen either.

This new band/tab tab label if I know that does not need to be there because he has never been before until I opened a new tab and logically would then use for tabs.

But, given that I don't like and I want not gone, I presume this means that it is new, because one or more persons thought redundancy is fun and there is no option to remove it either.

Someone can give information me in places where my ignorance cause me to suffer here? Give back me my thumb at the top of my screen and I promise not to ask for a mile!

Thanks to all who can / will help me.
Much peace

Did you try to uncheck the "always show the bar tab" checkbox in the options on the tab? See the tab preferences and settings.

I'm sorry, but you need to contact the manufacturer of Netbook on this subject.

There are too fishy advice on the Net start from USB to recommend a method

They will have the Options of reinstalling Vista available for their Netbook, because they produce a lot of them.

Take the Option to plant, where to do otherwise may affect your warranty.

Someone has changed my password to something I don't know, now I can't get into my computer without password. I have treid to reset without luck how to get back into my computer.

I tried to log in with my old password and then when it says the username or password is incorrect, I then click OK and it says pass Reset :) word, I enter my password and then click on reset password in my flash drive and I get not implementing wizerd giving me instructions on what to do. Help, please! I HAVE BEEN FIGHTING WITH this for MANY HOURS Thank YOU

You can use system restore to restore Windows to a date where your password still worked:
1. put your BIOS so that it uses the DVD drive as its primary boot device.
2 start the computer with your Windows 7 repair CD.
3. press a button if you are prompted to start from the DVD.
4. When prompted, select "Safe Mode Command Prompt".
5 log in as administrator if you are prompted.
6. Select repair when prompted.
7. When you are prompted, select System Restore.
8. set Windows to a point before this problem occurred.
9. When finished, remove the CD before restarting the system.
In step 2, you can also use the Windows 7 installation DVD. The subsequent steps are similar to those above.

When you're done, why not create a second admin account, then lock up its details. Next time you have a password problem, use the same way you use the spare key to your car when misplace you the master key.

Without .htaccess how can I block sites unwanted reference?

I've seen a few posts on .htaccess not working not not on BusinessCatalyst because it only works on Apache servers and BC is on .NET apparently (?). My client needs to block a dozen of bots (semalt, buttons for Web sites, best SEO, etc.) and while I can find a way to block the IPs reports of the site through BC, I don't think I can isolate IPs for each of these sites of delinquency. Then what should I do? I saw something maybe, it can be done in Google Analytics... but it actually block the visit or simply remove from being counted by the traffic report? I want to keep my protected site but I want British Colombia has my hands tied to this.
Any advice would be appreciated!

1. robots.txt for bots who read and follow

2. you are protected, things just to read your site can and will happen, even with htaccess on a website - can easily ignore it.

3. the filter is what you need and to better to spend his stats by google analytic as BC isn't as good at filtering.
