Is there a compiler switch to prevent mistakes in NSLog statements?

I keep making the same mistake, putting a float argument into an NSLOG statement and using %d to format it which of course returns ZERO.
float val = 123.456;
NSLog (@"my val=%d
", val);
---- the above statement will show 0 in the log, because of the incorrect type!
I realize i should use %0.f to get an integer value, but is there a compiler switch that will check on these parameters and warn you ?

Well, there is a compiler switch to detect mismatches in printf statements, and if you make a macro during testing that converts NSLog to printf then you can get the compiler to catch them!

Is there an output switch at the analog front end of PXI-6723 and PXI-6713?

I was reading the analaog output user manual and i could not find this. Is there any output switch just before the analog output of each channel for PXI-6723 and PXI-6713? I am would like to have total isolation between when these output are not needed. If yes, is there any specification to refer to?
Thanks.

Hello Chris,
I would recommend having a look at the examples in the LabVIEW
example finder to start with. In particular i would look at 'Cont Gen
Wfm-Ext Clk.vi' This is a basic example that allows you to output a
waveform through the card and source an external clock source to do
this. I would recommend exporting the sample clock that you wish to use
from the 4462 on one of the RTSI lines and then setting this as the
sample clock source for the Analog output card.
Another good example to look at is the 'Cont Gen Voltage Wfm-Int Clk
non regeneration.vi' This does not regenerate the same waveform in the
buffer but instead creates a new waveform to output after the previous
one has been written to the buffer.
It should be noted that there may be some gliltching if you are
updating the waveform. This is because the buffer will already have a
waveform in there to output before you input the new one so a new
frequency may not have an exact number periods that fit into the
pre-defined buffer. If you are looking to generate dynamic waveforms
then the best option for the best results would be one of our arbitrary
waveform generators here.
Good Luck,

If iTunes does not see your iPod then your only hope is a data recovery company. Not cheap.
However, you may be able to get some photos by:

- If they are in an iPod backup then restore another iPOd, iPhone or iPad from that backup. See the restore topic of:

DPF-0009 There were compilation errors

I am trying to use the Data Profiling tool incorporated in Warehouse Builder Rel 2 10.2.0.1
I am getting the above error "DPF-0009 There were compilation errors"
I traced back the problem to the fact that the user OWB_OWNER_PRF's password was changed. However, I did go into the Connection explorerer and update the pasword of the corresponding location. However, that has not helped.
When I run the profile it starts the validation process and the progress bar stops with the following message -
"OWB_PRF_OWNER_LOCATION (Create) - 1"
At that point the progress bar stops and I get this error.
I would really appreciate it if some one can give me some points about how this can be fixed ?
Thank you
Manav

Hi Manav
Are you profiling using a repository user (rather than owner)? If so, this may be bug 5338439.
If so there are a couple of workarounds:
1) Go into the control center, register all locations and then go back and perform the data profile.
or
2) Log in as the repository owner, go into preferences and select both persist passwords and share location passwords.
Cheers

I hate to have paid for it and have it go away. Help please!

Start by creating a second partition on your hard drive:
To resize the drive do the following:
1. Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
After the main menu appears select Disk Utility and click on the Continue button. Select the hard drive's main entry then click on the Partition tab in the DU main window.
2. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed. (Note: You can only make a partition smaller in order to create new free space.)
4. Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
You should now have a new volume on the drive.
It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss. Your drive must have sufficient contiguous free space for this process to work.
Install Snow Leopard on the new partition:
Boot from your Snow Leopard Installer disc. Proceed with reinstalling OS X. Be sure to choose your new partition as the target destination.
Download and install the Mac OS X 10.6.8 Update Combo v1.1 update. Any additional updates can be installed using Software Update.

Why there is implicit commit before and after executing DDL Statements

Hi Guys,
Please let me know why there is implicit commit before and after executing DDL Statements ?
Regards,
sushmita

Helyos wrote:
This is because Oracle has design it like this.Come on Helyos, that's a bit of a weak answer. :)
The reason is that it makes no sense to update the structure of the database whilst there is outstanding data updates that have not been committed.
Imagine having a column that is VARCHAR2(50) that currently only has data that is up to 20 characters in size.
Someone (person A) decides that it would make sense to alter the table and reduce the size of the column to varchar2(20) instead.
Before they do that, someone else (person B) has inserted data that is 30 characters in size, but not yet committed it.
As far as person B is concerned that insert statement has been successful as they received no error, and they are continuing on with their process until they reach a suitable point to commit.
Person A then attempts to alter the database to make it varchar2(20).
If the database allowed that to happen then the column would be varchar2(20) and the uncommitted data would no longer fit, even though the insert was successful. When is Person B going to find out about this? It would be wrong to tell them when they try and commit, because all their transactions were successful, so why should a commit fail.
In this case, because it's two different people, then the database will recognise there is uncommitted transactions on that table and not let person B alter it.
If it was just one person doing both things in the same session, then the data would be automatically committed, the alter statement executed and the person informed that they can't alter the database because there is (now) data exceeding the size they want to set it to.
It makes perfect sense to have the database in a data consistent state before any alterations are made to it, hence why a commit is issued beforehand.
Here's something I wrote the other day on the subject...
DDL's issue a commit before carrying out the actual action
As long as the DDL is syntactically ok (i.e. the parser is happy with it) then the commit is issued, even if the actual DDL cannot be executed for another reason.
Example...
We have a table with some data in it...
SQL> create table xtest as select rownum rn from dual;
Table created.
SQL> select * from xtest;
        RN
         1We then delete the data but don't commit (demonstrated by the fact we can roll it back)
SQL> delete from xtest;
1 row deleted.
SQL> select * from xtest;
no rows selected
SQL> rollback;
Rollback complete.
SQL> select * from xtest;
        RN
         1
SQL> delete from xtest;
1 row deleted.
SQL> select * from xtest;
no rows selectedSo now our data is deleted, but not committed, what if we issue a DDL that is syntactically incorrect...
SQL> alter tab xtest blah;
alter tab xtest blah
ERROR at line 1:
ORA-00940: invalid ALTER command
SQL> rollback;
Rollback complete.
SQL> select * from xtest;
        RN
         1... the data can still be rolled back. This is because the parser was not happy with the syntax of the DDL statement.
So let's delete the data again, without committing it, and issue a DDL that is syntactically correct, but cannot execute for another reason (i.e. the database object it refers to doesn't exist)...
SQL> delete from xtest;
1 row deleted.
SQL> select * from xtest;
no rows selected
SQL> truncate table bob;
truncate table bob
ERROR at line 1:
ORA-00942: table or view does not exist
SQL> rollback;
Rollback complete.
SQL> select * from xtest;
no rows selectedSo, there we have it. Just because the statement was syntactically correct, the deletion of the data was committed, even though the DDL couldn't be performed.
This makes sense really, because if we are planning on altering the definition of the database where the data is stored, it can only really take place if the database is in a state where the data is where it should be rather than being in limbo. For example, imagine the confusion if you updated some data on a column and then altered that columns datatype to be a different size e.g. reducing a varchar2 column from 50 character down to 20 characters. If you had data that you'd just updated to larger than 20 characters whereas previously there wasn't, then the alter table command would not know about it, would alter the column size and then the data wouldn't be valid to fit whereas the update statement at the time didn't fail.
Example...
We have a table that only allows 20 characters in a column. If we try and insert more into that column we get an error for our insert statement as expected...
SQL> create table xtest (x varchar2(20));
Table created.
SQL> insert into xtest values ('012345678901234567890123456789');
insert into xtest values ('012345678901234567890123456789')
ERROR at line 1:
ORA-12899: value too large for column "SCOTT"."XTEST"."X" (actual: 30, maximum: 20)Now if our table allowed more characters our insert statement is successful. As far as our "application" goes we believe, nay, we have been told by the database, we have successfully inserted our data...
SQL> alter table xtest modify (x varchar2(50));
Table altered.
SQL> insert into xtest values ('012345678901234567890123456789');
1 row created.Now if we tried to alter our database column back to 20 characters and it didn't automatically commit the data beforehand then it would be happy to alter the column, but then when the data was committed it wouldn't fit. However the database has already told us that the data was inserted, so it can't go back on that now.
Instead we can see that the data is committed first because the alter command returns an error telling us that the data in the table is too big, and also we cannot rollback the insert after the attempted alter statement...
SQL> alter table xtest modify (x varchar2(20));
alter table xtest modify (x varchar2(20))
ERROR at line 1:
ORA-01441: cannot decrease column length because some value is too big
SQL> rollback;
Rollback complete.
SQL> select * from xtest;
X
012345678901234567890123456789
SQL>Obviously, because a commit statement is for the existing session, if we had tried to alter the table column from another session we would have got
SQL> alter table xtest modify (x varchar2(20));
alter table xtest modify (x varchar2(20))
ERROR at line 1:
ORA-00054: resource busy and acquire with NOWAIT specified
SQL>... which is basically saying that we can't alter the table because someone else is using it and they haven't committed their data yet.
Once the other session has committed the data we get the expected error...
ORA-01441: cannot decrease column length because some value is too bigHope that explains it

Is there an obvious way to prevent an FPGA multiply from using DSPs?

In FPGA coding a High Throughput Multiply function will take advantage of any available DSPs on your FPGA. This is great, unless you have more multipliers than available DSPs. My FPGA code is currently failing to fit, and although it's using just 50% of the Registers/Slices, it's trying to use more DSPs than are available (My Virtex 5 chip has 64 DSPs).
In the help I'm pretty sure it says the compiler will revert to using slices for multiplications in the absence of sufficient DSPs, but my experience is otherwise.
If I convert just one of the High Throughput Multiply functions to a standard LabVIEW Math multiply primitive I receive timing errors from the compiler (even though there are minimal timing constraints in my code), and it therefore still fails to compile.
So my question is: Is there a way to prevent a Multiply function in LabVIEW FPGA from using DSPs?

Dragis wrote:
Unfortunately, this is a bug/feature of the Xilinx tools. Once the tools have decided to choose DSP blocks for the multipliers, it will only use them and not place any in logic. There is a way to disable automatic usage of DSP blocks, you'll have to work with NI customer support to make that change. If you use this option, you'll have to manually drop the High Throughput Multiplier everywhere you want a DSP48 to be used.
I've gone through Technical Support with this issue once before about a year ago and there was no mention of a 'solution', just the unhelpful suggestion to "use fewer multipliers". I'll raise another support case and link to this thread, maybe they'll need to speak with you directly to understand what this option is.
I'm perfectly happy, in fact I'd prefer, to be able to specifically select where a DSP is and isn't used for a multiplication. If reasonable, I'd suggest this option to disable automatic usage of DSPs be made public (either through the knowledgebase, or as an actual feature in the FPGA toolkit perhaps).
Thanks Dragis.
