How to escape and wildcard expand?

Hi,
I have a context index and a web app where users may search. As a matter of fact users may use "-" or "&" when they search for company names, so I have to escape these before passing it on to oracle text.
I would like to use a wildcard expansion to the right for one special search - but I don't know if I have to escape each special char (replace "-" with "\-", "&" with "\&") or if it is possible to accomplish both goals with "{ }" and "%" - but
{foo}% results in an error and {foo%} only searches for foo.
DB is a 10.2.0.1...

>
How would I go about escaping the wildcard (*) in a query and have it treated as literal text?
>
You don't need to since '*' is not a wildcard except when it is used to specify 'all columns' in a select query.
Perhaps you are using 'wildcard characters' to refer to the pattern matching characters '_' and '%' used in 'LIKE' clauses.
These can be escaped in the LIKE clause by specifying using the ESCAPE clause
See LIKE Condition in the SQL Language Reference

How to escape % or % in a String?

Hi, friends, I need to use a string variable, but don't know how to escape <% and %> in string, I tried to put \ between < and %, but compiler said it was invalid escape character. and do I need to escape / , too? thanks for any help. the code is here:
<% String sc;
if (request.getParameter("operation")==null) {
sr="/servlet/littleBee_proj.Change_PCServlet?red=<%= request.getParameter("red")%>&
green=<%= request.getParameter("green")%>&blue=<%= request.getParameter("blue") %>&
applique.x=<%= request.getParameter("applique.x") %>&
applique.y=<%= request.getParameter("applique.y") %>";
else {
sr="/servlet/littleBee_proj.Change_PCServlet?red=<%= request.getParameter("red") %>&
green=%= request.getParameter("green") %>&blue=<%= request.getParameter("blue") %>&
applique.x=<%= request.getParameter("applique.x") %>&applique.y=<%= request.getParameter("applique.y") %>&
operation=<%= request.getParameter("operation") %>";
%>
<br> <INPUT TYPE="IMAGE" NAME="applique" SRC="<%= sr %>" >
</FORM>
</BLOCKQUOTE>

You won't need the escape characters, because you don't need the <% and %>. You're already inside a java block, so go ahead and take advantage of it. Simply append the method call to your string as you usually would.
<% String sc;
if (request.getParameter("operation")==null) {
sr="/servlet/littleBee_proj.Change_PCServlet?red="+request.getParameter("red")
+"&green="+request.getParameter("green")+"&blue="+ request.getParameter("blue")
+"&applique.x="+ request.getParameter("applique.x") +"&applique.y="
+request.getParameter("applique.y");
}Also, unless you know exactly what you're getting back from your request.getParameter() methods, it's usually a good idea to enclose them with single quotes ( ' ) in case there's a space or something in there. If there guaranteed to be numeric though, then you're probably ok.

How to read and display a signal from my PIC Microcontroller onto Labview

Hi,
I am doing a project on a Pulse Oximeter and i am trying to read and display the signal from my PIC Microcontroller on Labview? How do i go about doing it? I am using the PIC16F877 and also making use of the USART?
How do i implement and initialise the USART in PIC16? What are the steps to be taken, please guide me through the process? The link provides information regarding the USART connection, initialisting and stuff? Is it correct to use these codes in my program?Link: http://ww1.microchip.com/downloads/en/AppNotes/00774a.pdf
Also, i am using the RS232 serial interface to connect to the PC? The connector i am using is the DB9 Connector. Which template and VI can i use? Am i supposed to use the NI-DAQmx and VISA? Also, for my USART connection, i am using the MAX232 Driver which is applicable for my application as i am working with +5V. So far, i have been reading and trying out on Labview and the steps i have taken are:
1) Open a New VI and used the Instrument I/O(Read & Display) template?
2) How do i configure the Instrument I/O Assistant Express VI to read the info from my device connected to COM1?
3) I was reading the Labview Manual, 'Getting Started with Labview' and i was following the steps under Page 55, Communicating with an Instrument. Am i on the right track?
4) How do i check and make sure that the port settings of the I/O Assistant and my PIC Micro Match
Please help me out and guide me through the process. I am student at a polytechnic and i am very new to Labview and the software is used as a development tool for the project. I have a deadline to meet and i hope i can get a response as fast as possible. Your help will be kindly and greatly appreciated. I hope to hear from you guys soon.You can e-mail me all your answers at [email protected]
Thank You
Best regards,

Hi Ashwin,
I am not familiar with the PIC Microcontrollers, but I am assuming you mean that you have the microcontroller sending out serial data that you want to read on another computer with LabVIEW. Please let me know if this is incorrect.
What type of data is coming out of the serial port? Is it ASCII, or binary? The reason I ask this is that the serial communication in LabVIEW is done through a protocol called VISA, which uses ASCII data to send and receive. You can later convert this data into whatever form you need, but this is what it is designed to read and write.
You can check the settings such as baud rate and data bits in a configuration utility called Measurement and Automation Explorer, or MAX. When you open up the MAX interface, you can expand the Devices and Interfaces entry on the left, and then expand the Ports entry to see your serial port. When you highlight this port, select the Port Settings tab at the bottom of the window, and you can see what the current settings are, and change them if you need to. You can also set these parameters in LabVIEW using the VISA Configure Serial Port VI.
You can also test communication in MAX by right clicking on the correct port and choosing Open VISA Session. Then choose the Basic I/O light blue tab, and then go to the Read tab. When you click execute, it should read in what is coming from the serial port. This will allow you to verify that the correct information is coming in before even trying to acquire the data in the LabVIEW environment.
In LabVIEW, the best resource to use the Basic Serial Write and Read example program that ships with LabVIEW. By examining the block diagram of this program, you will be able to see the basic programming flow of serial communication in LabVIEW.
I hope this information was helpful! Please let us know if there's anything else we can help with.

here the step :
Solstice DiskSuite[TM] Software: How to Delete and Reset a Lost Root Password on a System With a Mirrored Root Disk [ID 1010755.1]
Solution
Steps to Follow
How to delete and reset a lost root password on a system with a mirrored root disk.
1) Insert the Solaris[TM] Operating System CD-ROM into the CD-ROM drive.
2) Once the CD-ROM is in the drive, perform a stop-a. This brings the system down to the "ok" prompt.
3) From the "ok" prompt, perform a single-user boot from the Solaris OS CD-ROM.
ok boot cdrom -s4) At the "#" prompt, determine which disk is the system's boot disk (containing the root file system). There are several Oracle architectures and various configurations of systems when it concerns a boot disk. As a general rule, most boot disks are attached to controller 0 (c0). Usually, their SCSI target is
either 3 (t3) or 0 (t0). However, Oracle machines are very flexible, and the boot disk could be at a different location. If you are not sure which disk is your boot disk, perform the following steps to determine the location of the boot device:
a) # eeprom boot-device
The output might appear to be simple, such as "disk" or "disk1" or more complicated, such as a pathname "/iommu/sbus/espdma@4,8400000/...../sd@3,0:a".
b) Make note of the boot-device. If the boot-device is a pathname, it is beyond the scope of this information to provide the location of the customized boot disk. However, for most configurations,
finding the customized boot disk is an easy task. The "Format" command shows all available disks:
#format
Searching for disks...done
AVAILABLE DISK SELECTIONS:
(enter its number): c) Enter d to exit format.
Now, you will have an idea what disks are on the system. Therefore, if the boot-device is "disk" and format shows "c0t0d0" (on some systems "c0t3d0") then that is the boot device. If boot-device
shows "disk1" and format shows "c0t1d0," then that is the boot device. If format shows multiple disks, then based on what the "eeprom boot-device" command shows, the system's boot disk would be:
boot-device format
disk c0t0d0 or c0t3d0 (machine dependent)
disk1 c1t0d0
disk2 c0t2d0
disk3 c0t3d0 or c0t0d0 (machine dependent)
and so on ....
5) Because the system was not brought down gracefully (no root password means having to use the Stop-a keystroke to "crash" the system), you need to run "fsck" to clean the root partition (slice). The fsckalso confirms that you selected the proper slice.
# fsck /dev/rdsk/c1t0d0s0
where the X and Y are determined by the previous procedure. It is also possible to have a root partition which is not on slice 0 (s0), but, again, that is not a standard configuration.
The output of "fsck" looks like this:
** /dev/rdsk/c1t0d0s0
** last mounted on /
** Phase 1 .....
The second line in the output of "fsck" ("** Last mounted on /") confirms that this is the correct root filesystem partition. Answer "y" to any questions fsck asks. There shouldn't be too many items
needing repair. If there are, there is a possibility of a corrupted root filesystem. After fsck is finished, mount the root partition:
# mount /dev/dsk/c1t0d0s0 /a
Again, X and Y are the same as for the fsck command.
For example:
# mount /dev/dsk/c1t0d0s0 /a
6) From the root prompt, set the proper TERM type command (such as vt100, dtterm, sun, and so on)
by entering this command:
# TERM=sun; export TERM
7) Use the VI text editor to edit the /etc/shadow file:
# vi /a/etc/shadow
8) The first line of the /etc/shadow file is the one you want to modify.
It looks like this:
root:c3.yAVmYodWsc:6445::::::
9) Delete every character between the first and second colons in the first line of the file. When you finish deleting the characters, the line should look like this:
root::6445::::::
10) Press the Escape key, then enter the following to save the file and exit vi:
:wq!
11) Use the VI text editor to edit the /etc/system file andremove the "rootdev" line shown below:
# vi /a/etc/system
*rootdev:/pseudo/md@0:0,0,blk
Don't comment out the "rootdev" line. Actually remove it.
12) In the /a/etc/vfstab file, replace the lines for the system filesystem meta-devices with their underlying partitions. For example, change lines from
/dev/md/dsk/d0 /dev/md/rdsk/d0 / ufs 1 no -
to
/dev/dsk/c1t0d0s0 /dev/rdsk/c1t0d0s0 / ufs 1 no -
ONLY change the lines for root (/) and the filesystems that were affected by the actions you took in step 1 of this procedure. All other metadevices may stay as is in this file.
13) Unmount root, check the root filesystem, and then stop the system:
# cd /
# umount /a
# fsck /dev/rdsk/c1t0d0s0
# stop-a
14) Boot to single-user mode:
ok boot -swTHIS STEP IS VERY IMPORTANT; YOU MUST BOOT TO SINGLE-USER MODE TO AVOID FILESYSTEM CORRUPTION.
If the system does not boot to single user mode, you might have made a mistake in the previous steps.
15) Because the root password was cleared in an earlier step, press Return when prompted for the the root password. Once you are in single-user mode, you must clear the metamirrors and all the sub-mirrors for the root filesystem. For example, if root (/) is d0, run the following command:
# metaclear -f -r d0
Running the metaclear command not only clears the metamirror but also clears the submirrors that are part of this mirror.
16) When the metamirror is cleared, continue the boot up to multiuser mode by either pressing CTRL-D or by entering the following:
# exit
Now everything should be as it was, except that the system partition is on the underlying partition and isn't mirrored. You will simply need to re-create the metadevices for the root mirror as you had originally.
many thanks

Hi,
Halt your machine.
Boot with fail-safe mode.
format and list out the disks. (You can get the root & mirror disk (c#t#d#) details from /etc/lvm/md.tab of your root or mirror disk. Earlier explorer output may help)
Mount the root disk and remove the password entry in /etc/shadow
umount it.
Mount the mirror disk and remove the password entry in /etc/shadow
umount it.
reboot the server.
Hope this helps!

Hi Sandra,
First of all thaks for your quick answer to my problem.
I see what you mean and get the same result, if I am using data-type string instead of xstring. But the recommendation in the XML-Books of SAP is to use XSTRING to save memory and circumflex problems between Codepages, when writing the XML-Stream to a filesystem.
As you can see in the code abvoe I am using a SAP-FM to display the XML-Stream and this FM works only with XSTRING´s,
that is one reason why I don´t understand that it displays it in the wrong way.
Even the Debugger shows me for the XSTRING the wrong result. Does all that mean that the escaping will not be applyed if you are working with XSTING´s??

How to escape the special character ' (ascii 39) in a select query?

Hi,
does anybody know how to escape the special character ' (ascii 39) in a select query?
I've tried a lot of ways but nothing seems to work, for example I try to get all
names in table foo where coloumn name contains a '-sign (ascii 39)
select name from foo where name like '%\'%';
select name from foo where name like '%{'}%';
select name from atg_horse where name like '%chr(39)%'
... but neither works, I end up with a ORA-01756: quoted string not properly terminated
I would apriciate any help

friends
thanks for ur time and effort that u gave to reply to my problem.
But my main problem is that when my application (VC++ 7) fires the following query in the oracle database , it does not return any rows.
SELECT count(*) FROM ORGANISATION WHERE UPPER(ORGANISATION.ORGANISATIONNAME)
LIKE N'β%' ORDER BY ORGANISATION.ORGANISATIONNAME
the above question in the previous thread was just to check on sql plus as it's editor does not support unicode characters.

Could you capture your screen and post it. Have the layers panel open and any layers that are collapsed, expanded. We will need to see the entire screen, as some information in the tab is important as well.

How to Create Infoset Query (SAP Query)
Steps on how to proceed to create a Query:
ADHOC QUERY
A query can be created to extract information from master records i.e Infotypes. For example, by creating a query , the data relating to an employee contained in various Infotypes can be extracted.
Proceedure :
Decide on the various Infotypes we want to make the query. Decide on the area where we want to query i.e Global area or Standard area. Standard area is client specific and globel area will include all clients.
Menu : HR PM Admn - Information System - Adhoc Query
Select area standard and select the user group already created
Creation of new query :
TC SQ03 - Select Environment Select Standard Area - Enter -- If new user group is to be created, enter name of the user group, click on create and enter necessary information and exit after saving
TC SQ02 - Enter name of the Infoset Create enter name of Infoset - Data source -- > Table join by basis table give name of table e.g pa0000 - Enter - Click on insert table if we want to include more tables give name of table one by one and after finishing, place cursor on the joining lines and right click to delete unwanted relationships - check - and go back - field groups - include all table fields - click on generate button   - go out
TC SQ03 - Select user group -   eg. Payroll
Infoset - Enter name of newly created Infoset
Assign users and Infosets - Assign infosets - put tick on payroll - save and go back
TC PAAH - Expand the nodes and put tick on relevant fields depending upon necessity
Save the query by giving the same name as infoset for easyness..
For executing a query which is already created
1. Go to SQ01 transaction
2. Go to Environment menu->query areas->std areas
3. Then choose the user group where the query is created
4. It will display all the queries created for the group.choose the query you want to executeand click execute.
5. will take to the initial screen
6. Enter the required parameters and execute

How do you ungroup or expand a pie chart in Adobe Illustrator CS6?

How do you ungroup or expand a pie chart in Adobe Illustrator CS6? This functionality seems to have been removed. Say I'd like to remove the legend: before, I could ungroup the chart, release its link to the data, and then delete the legend with my white mouse. Object > Expand no longer works either. This is supremely frustrating.

In the end, I closed the dialogue box that shows the data, and was able to choose Object > Ungroup. Then it prompted me saying: "The selection contains a graph. After a graph is ungrouped you will no longer be able to access its graph style, its data or change its graph designs." - Which is what I was looking for. So in short, when the data is open, everything under Object will be greyed out. Additionally, Object > Expand no longer works in CS6.
As a note, before I figured all this out, I resorted to a quick clipping mask to get rid of the legend, since selecting with the direct selection tool (A) and deleting was met with a 'you can't do that' prompt. That worked nicely, and kept the data.

How to Start and Stop Processes?

How to Start and Stop Processes?
Im trying to create a program which allows me to Start and Stop (and Restart) GameServers. I will then expand on this so i can start and stop them through a web applet with build in useraccounts.
Currently the way we do this is to log into the server using a RemoteAssistance. Which is not very safe as the users have the abbility to do anything on the server and potentially corrupt it.
Below is my code for how i start the servers. But i dont know how i would stop the process.
                private void startServers()
               for(GameServer gs : servers)
                    int ID = Integer.parseInt(gs.getID());
                    if(isChecked(ID))
                         try
                              String cmd[] = gs.getStartString();
                              Runtime.getRuntime().exec(cmd);
                              int sleepPeriod = Integer.parseInt(sleepField.getText());
                              Thread.sleep(sleepPeriod*100);
                         catch(Exception e)
                         System.out.println(e);
               }//end of iterator
               JOptionPane.showMessageDialog(null,"All Selected Servers Have been started.","Servers Started",2);
     }//end of startserversAnyhelp would be great thanks.

Using the process class would give you a nicer API, but using destroy isn't a nice way to shutdown a process. Its like killing the process with your task manager. You should make a connection in some way with the game server and tell it to shutdown in stead (gracefull termination).

How to escape string that SQLCMD thinks is a variable but isn't.

Hi All,
I've got a SQLCMD script where I use :setvar like I usually do. As part of its work it calls a stored procedure that has a parameter whose value is a string. Part of the string being passed looks like this.
Objects="$(INSTANCE)"
Now my SQLCMD script is throwing and error like the following.
A fatal scripting error occurred.
Variable INSTANCE is not defined.
How do I escape that $(INSTANCE) inside the string that SQLCMD thinks is a variable for it to use so that the string gets loaded into the table as it supposed to be? I'm failing to find how to escape
a variable that isn't actually a variable.

To anyone interested I was able to solve this. In the string being passed in as a parameter I was able to replace the $ with
+
CHAR(36)
+
and it works perfectly.
