Using int pointer as parameter in dll, but the value of parameter doesnot change

Hello, I have a function in dll as void set(int * a){ (*a)=99;}
And I connect a int32 to the dll. But when I run the vi, the value of int32 does not change.
As the pic shown below:

You connected a control to the DLL parameter. That means the value from the control is passed to the DLL, ... and finito! You need to connect an indicator to the right side of the DLL parameter to see the value returned from the DLL.

Parameter List displaying all the values on Parameter form

Dear All...If I uncheck the "Restrict List to predetermined values" option, then report parameter form displays all the values on web parameter form instead of displaying those values in the List Item. Is it the Default behaviour of Oracle Reports 10g or Can I control it anyway because if I've 1000 entries in a list, then displaying all those values openly on the form is an ugly thing and it increases the size of parameter form very much.

Hello,
A solution is provided in the Note :
Note.465886.1 How to Implement an Alternate Solution to Unrestricted List Of Values (LOV) in Parameter Form on the Web:

If the thief enabled activation lock on the device, then there is nothing that can be done. Only the password for the Apple ID that it is locked with can disable activation lock.

I have an iPod mini 6GB and want to use it with a Sony CD Boombox but the adapter is different. Can it work?

I have an iPod mini, 6 GB and want to use it with a Sony CD Boombox but the adapter is different. Can it still work? Don't want to try and break iPod.

Do you mean that the iPod mini won't fit on the "dock" because of shape (of the iPod), or is the docking connection a different type from the "30-pin" dock connector on the iPod mini?

I tried updating iphone 6 to 8.1.3 But the phone went dead. I have tried using restore options - both update and erase, but the process stops when it tries to update Iphone firmware.

Put your phone in DFU mode,
Hold the Power Button (3 secs)
Continue holding the power button and also hold the home button (15 secs)
Release the power button while continuing to hold the home button (10 secs)
Your device should prompt with the "Connect to iTunes Screen"
Restore.

We have 2 locations using formscentral one location is working fine but the other location is experiening slow response (up to two hours) or the form not displaying? What should be looked at?
Thanks
Carleen

Can you describe what you mean by "experiencing slow response"? Do you mean that you don't see the new responses as they come in? Does it takes up to two hours before they show up in the View Responses table when they show up immediately at your other location? And what do you mean but "the form not displaying"? Are you talking about the fillable form or the editable form in FormsCentral?
Can you please add me as co-author ([email protected]) of the form so that I can investigate on my side.

Looking at the error message "The Network Adapter could not establish the connection" , It appears hostname and port may be incorrect. Review the targets.xml under E:\oracle\product\10.2.0\db_1\SAP_solman_SDB\emd and
emoms.properties under E:\oracle\product\10.2.0\db_1\SAP_solman_SDB\config folder to make sure host ( sap_solman) and port (1527) are correct.
As far as setting the environment variables goes, you can go to control panel -> system -> advanced -> environment variables and set the ORACLE_HOME and ORACLE_SID

Hi NWL1,
Thanks for the question. If I understand correctly, the iPhone won't update and is stuck. I would recommend that you read this article, it may be able to help you resolve or isolate the issue.
If you can't update or restore your iPhone, iPad, or iPod touch - Apple Support
Thanks for using Apple Support Communities.
Have a great day,
Mario

You cannot. Your best course of action is to immediately change all your internet passwords, notify the police and your insurance company. Send the remote wipe command to the MBA through iCloud.com and buy a new one from the insurance reimbursement.

Change the value of parameter in smartfrom by program lines...!

Hi experts.........!
i want to change the value of parameter 'x1' which i import from program has a value 'ECNC' and want to display in output of smartfrom as 'ECNEC'. how i change it from program lines.
I use program lines to change its value....... use input parameter 'x1' and output paramter 'x1'
and program lines are
IF x1 = 'ECNC'.
x1 = 'ECNEC'.
ENDIF.
and in condition i use
x1 = 'ECNC'
but it doesn't effect output is same as it show the value of x1 = 'ECNC' when i execute the program.
How i change the value of x1 to 'ECNEC'
Plz help me.......!
Thanx in advance....!

Hi ,
Have you declared the Variable X1 under Global Definitions ?
please debug the Smartform by the following way.
Goto the generated Function module - > Search for your Variable X1 ( Choose Main program )- > Set Break point
Debugger will be called after giving printing parameter automatically. Check it whether value get changed ( Your Code is working or not ).

Determine/read the value of parameter rdisp/max_wprun_time within ABAP

Hi,
I need to avoid program breaks caused by exceeding run time longer than defined in parameter rdisp/max_wprun_time.
I will check the time since start of report in the critcal loop to bring the current data changes to a controlled end before getting a program break. I won't put a constant to the report, I will have a dynamical routine to avoid changes of report if the value of parameter rdisp/max_wprun_time will be changed.
But how can I get the value of this parameter within my ABAP report? Is there a table where this value has been stored? Is there an existing function module or a method to read the value?
Thank's a lot in advance!
Georg

The runtime parameter (GET RUN TIME ) can be used to dynamically get the program run time
DATA T TYPE I.
GET RUN TIME FIELD T.
WRITE: / 'Runtime', T.
or
U probably can store the start date and time in TVARV with some variable ( line concatenate program name + START Date + Time)
and then use
SD_DATETIME_DIFFERENCE
or
SD_CALC_DURATION_FROM_DATETIME

That"s part of my problem, I dont get that option.
I get iTunes store and that's about it.
I've thought about "erasing/resetting" all settings but I'm afraid to do it. Or am I
missing something in iTunes?
Help please!
