How to replace substring with a char

Hi,
Suppose i have
String x = "abcdabcd";
i need to replace string from index 1 till index 2 ( i mean the initial bc) with "T" so that x becomes
x = "aTdabcd";
is there any easier way or direct function in Java 1.3 to do that. i was checking sun website but didnt find any.
Plz guide me. thanks

public String replaceSubstring(String string, int start, int end, char c) {
return string.substring(1, start) + String.valueOf(c) + string.substring(end) ;
}Not sure if its exactly right but you get the idea (cant be arsed checking it). Honestly, try to come up with something before asking

You need to upgrade the computer's OS. Open the Mac App Store and try downloading Mavericks. If you get told it's incompatible, choose About this Mac from the Apple menu, check if the computer has at least a Xeon or Core 2 Duo(not Core Duo) CPU and 2GB of RAM, and if it does, click here and order a download code for Lion 10.7.
Back up your data before upgrading. Mac OS X 10.7 and newer don't support PowerPC programs such as versions of Microsoft Office prior to 2008.

Replacing space with special char in reporting

I have created a calculatd Keyfigure where if the consition given in the calculated KF satisfies then it displays 1 otherwise space ,now mu user wants space to be replaced by some special charcter
Example
My ckf is like this overallscore >= 90 & Iam applying count on this
Vendor   CKF
X              1
Y
Z                1
As vendor y is not satsifying the condition its showing with space now I want to replace space with some special char how is this possible

Hi Priya,
You can try this: Instead of space, fill this with a 0. Then in the query properties, set the Show Zero As and give your special char, like may be *. But this will be okay if you do not have other zeros in the report...else you may need to do some VB coding.
Hope this helps...

Yes, it does so, because somebody forgot to upgrade the BASIS SP as well...
What BASIS SP are you using?

How to replace numbers with text in tax return pdf using Adobe Acrobat X Pro

How do I replace numbers with text in tax return pdf using Adobe Acrobat X Pro? The tax return was created using CCH software. Thanks for your review.

Thanks Bill for your quick reply. CCH software is one of the major
suppliers of tax return software. I found an internal source that helped me
make the changes from numbers to text i.e. "$123,456" to "See Schedule O".
I am not sure if I am working in form or final text. Thanks again! Kelly

How to do substring with Expression Builder

Hi,
I only execute a substring with Expression Builder, this is possible?
thanx

Hi!
With Expression Builder it is not possible as the EL by default does not have such function.
But you may:
1. Use JSTL 1.2 functions like "${fn:trim(' MYSTRING '}"
2. Write your own function and TagLib - see on net
Also, you may write a custom Map implementation and expose it in some backing bean to make it available in EL without need to create TagLib (as #{mybean.trim[' some string ']"). But this way is much complex if you need more than singe parameter for your function...

How to replace IMessage with Ichat

I have recently updates to os x mountain Lion, and Ichat has been replaced. I hate IMessage how do i get back Ichat.

HI,
The iChat App is specific to each Update within an OS X version run.
Messages is the version on Mountain Lion.
At OS X 10.8.2 it became version 7.0.1
That is to say that version 7.0 lasted for OS X 10.8 and 10.8.1
You can get Messages to look somewhat iChat like.
Lets say you have AIM (or AIM valid) Names and some Jabber IDs (including GoogleTalk or Facebook)
Either Add them in Messages the same way you would have in iChat (Use the Plus icon in Preferences > Accounts) or by activating the choice for Messages in System Preferences > Mail, Contacts and Calendars for any ID/Name you use in Mail or elsewhere.
This will give you a list of Accounts in the Messages Menu > Preferences > Accounts including the iMessages one and the Bonjour one.
If all are Enabled then the Window menu will now show Buddies (CMD + 1) in addition to the Messages (CMD +0)
If you use this you will see a combined Buddy List.
The can be unlinked by going to Messages > Preferences > General Section and Unticking the line that talks about "gather all accounts in to one list" (actually it is only Buddy lists Account and does not include the iMessages account)
The Window Menu will now list as many Buddy lists as you have Accounts (Less the iMessage one and any that are not logged in.)
Each will have it's own keystrokes listed.
The title of the Buddy list and the Name in the Window Menu is dependant on the Description Field in the accounts pane.
Example Pic of the Accounts Prefs pane with Buddy lists
The iMessages account does not have to be active.
The main draw back is the Messages window itself with it's dual purpose Tabbed Chat window and interface to start Chats without using the Buddy lists.
Double clicking a chat will open it in it's own window.

How to replace lvlib with lvlibp programmatically

Hello,
in the project explorer there is the possibility to do a "Replace with a packed library" from the context menu.
How can I do this programmatically?
Thank you.
Christian

I have a specific use case for this, and was wondering if anyone figured out how to do it. My Google search does not turn up much other than this thread.
My use case: I have main code branch that is not ready for LVLIPB's because the architecture is not 100% complete. However, we are release an Executable build on that relies on a pluggable actor framework architecture. Currently I manually branch the code, replace all LVLIB's with LVLIBP's then build additional LVLIPB's from that code and go back and replace the LVLIB's. At that point my code is now ready to be build as an executable with plug-ins. This process takes about 1-2 hrs to complete. This process works and works well repeatedly, it is just time consuming due to the relining. If I could just off load it to another PC that would enable to me to make additional bug fixes or work other issues in the main code branch. Currently we build about once a day or two for final release testing.
Any help in to script this would be much appreciated.
Thanks!

How to replace Consolekit with systemd-loginctl

Is systemd's new multiseat ready to replace consolekit?
And if, how can I achieve that?
My Background:
- I use systemd as my init system
- login into a getty
- which create a new X session with startx through a login script
I have had a hard time before I had the right setup to supervise everything with *ck-launch-session* and *dbus-launch* (order matters).
And sometimes without a reason, something breaks and I'm not allowed to mount USB drives or shutdown as a user without a reboot.
Last edited by Mic92 (2012-06-01 13:36:59)

I do have a session:
┌─[jente @ lappy ~] 21:48:14
└─■ loginctl
SESSION UID USER SEAT
1 1000 jente seat0
1 sessions listed.
I start Udiskie through .xinitrc, like so:
if test -z "$DBUS_SESSION_BUS_ADDRESS" ; then
eval `dbus-launch --sh-syntax --exit-with-session`
fi
exec bash -c "udiskie & $HOME/.bin/dwm_start"
With .bin/dwm_start:
#!/bin/bash
while true; do
dwm >/dev/null 2>&1
done
EDIT: Here's udiskie's output when I plug in my external HD:

failed to mount device /org/freedesktop/UDisks/devices/sdb1: org.freedesktop.UDisks.Error.PermissionDenied: Not Authorized
EDIT2:
Changing my .xinitrc to the following didn't help either:
udiskie &
exec $HOME/.bin/dwm_start
Also, I found out I have to enter my root password to shutdown/reboot, whereas I didn't have to before.
