Unable to resolve reference/Cannot find Canvas

Hi,
I have generated a form with Designer 6i. It has 3 tabs. On the second or third tab, when I diminish the width property of a BOUND TEXT ITEM , I get 2 error messages one after the other :
- FRM-40105. Unable to resolve reference to item <item name>. ...
- FRM-41053. Cannot find Canvas--invalid ID.
If the width is equal or bigger than its original value, it works fine. As soon as I change the value to a smaller one, it doesn't work anymore.
Any help would be appreciated,
Denise

Hi,
When you reference an item using:
set_item_property(<varchar2 field>, ...)
you should format the item name as:
'BLOCKNAME.ITEMNAME';
For example, set_item_property('NCP.B', enabled, property_true);
The colon is only used when you actually want the value of the item.
I can't remember, but this might be case sensitive too - so use uppercase.
Cheers
Chris

Suppressing unable to resolve reference to parameter... message

We have converted our applications to Oracle 9I (Internet) from Oracle 5 (Client Server).
We force a closing of an extra browser window by creating a .pll with a customized function called close_browser which runs close.htm and then does an exit_form to replace exit_form. We have forms call other forms, if the form is called, then it checks a forms parameter called parameter.pr_called. We want to just modify the library and not modify 100s of forms but :parameter.pr_called does not exist in a number of forms but we need to check parameter.pr_called with a NAME_IN in the library just in case it is called so we don't close the browser window if the form is a called form. It would then simply exit form and go back to the original form. When we check for name_in('parameter.pr_called) = 'Y' to check for this condition, we get unable to resolve reference to parameter pr_called.
We have tried changing message levels, but that only works for error messages and not messages. There seems to be no programming way to do a find_parameter for a form parameter. Any suggestions on how to prevent the message from appearing. We would not want to modify all the forms.
Thank you,

If you want to add this parameter to all your forms in batch - this is simple to do with the Java API - here's some sample code.
package oracle.forms.jdapi.demos;
import oracle.forms.jdapi.*;
public class AddParam
public AddParam(String formName, String parameterName, String parameterValue)
    try
      // Open the module - this implicitly starts JDAPI
      FormModule form = FormModule.open(formName);
      System.out.println("Processing " + form.getName());
      // see if the parameter already exists
      ModuleParameter param = null;
      try
        param = ModuleParameter.find(form, parameterName);
      catch (JdapiException cjdex)
        System.out.println("Parameter not present needs creating...");
      if (param == null)
        // create the required Param
        param = new ModuleParameter(form,parameterName);
        param.setParameterDataType(JdapiTypes.PADA_CHARACTER_CTID);
        param.setMaximumLength(3); //assuming Y/N, YES/NO??
        param.setParameterInitializeValue(parameterValue);
        System.out.println("Parameter created...");
        //we've made a change so save...
        form.save(formName);
        System.out.println("Form Saved...");
      else
        System.out.println("Parameter already exists...");
      form.destroy();
      Jdapi.shutdown();
    catch (JdapiException jdex)
      System.out.println(jdex.toString());
   * @param Pass the name of the Form as an agument to the class
public static void main(String[] args)
    String paramName = "PR_CALLED";
    String paramDefaultValue = "N";
    AddParam addParam = new AddParam(args[0], paramName, paramDefaultValue);
    System.exit(0);

replace go_item(':sub.subcode');
to
go_item('sub.subcode');Hope this works

See error Frm-40105 : unable to resolve reference to item 20.

hi master
sir when i put this code on when_button_press then give this error
go_block('emp');

:emp.deptno := 10;
execute_query;
error
Frm-40105 : unable to resolve reference to item 20.
sir please give me idea
Thanking you

Frm-40105
Cause: Runtime error. A GO_ITEM statement references a nonexistent item.
Which suggests that there might be some code in your form which causes this error (in)directly.

FRM - 40105 : Unable to resolve reference to item item name

Hi,
FRM - 40105 : Unable to resolve reference to item <item name>
When I am opening a form I am getting the above mentioned error. Instead of <Item name> how we can display the error like <:CTRL_BLK.DOC_DATE>
Thanks & Regards,
Jenson

Hi,
Actually I know what is the reason for getting this error. What I tried to ask you is any way to display the item name, which error is occurred.
In the form around more than hundred item setting the SET_ITEM_PROPERTY , there only I am getting this error. Like this around more than five form I have to debug. I would like to know through error handling routine or some other code we can display the exact item name, which error is occurred.
Thanks & Regards,
Jenson V.A.

I have HugesNet Gen4 and have downloaded most current version. I am unable to open and cannot find where in system preferences and/or Safari I give permission. Can a techie tell me where?

Because I downloaded from internet, I am unable to open. I cannot find where I give permission and/or if I need to download some plug in or something. Please help and thanks.

Hello Charlene,
It sounds like you are getting a message that the application you downloaded can't be opened because it's from an unidentified developer.
Gatekeeper is a feature of Mac OS X that by default blocks software from unknown developers, but you can change the functionality to download and install software from developers you trust:
Gatekeeper gives you more control over what you install. You can choose the safest option and only allow apps that come from the Mac App Store to open. There is also the option of only allowing apps that come from the Mac App Store and identified developers. Or you can choose to allow any apps to open, just like previous versions of OS X.
Gatekeeper options are found in Apple menu > System Preferences… > Security & Privacy > General tab under the header "Allow applications downloaded from:"
If you trust the source you are downloading the application from, you can switch the option to "Anywhere" to download the file. Once you finish downloading the file, you can always switch back to one of the other options.

Cannot find canvas! Help please!

I have somehow lost my canvas. The standard "layout" option is not bringing it back up. I have reinstalled and still no luck. Can anybody help me? Also my preferences menu is freezing up.

This fixed the same problem I was having thanks to Nipsey and Patrick
If the UI is missing its usually because the Pro Application Support is missing or out of date for your configuration.
If you're on Tiger:

If you're on Panther:

If you've installed this in the past, remove the ProAppRuntime.pkg from /Library/Receipts/ This will trick the update to reinstall completely instead of possibly skipping any bits.

Frm-40105 unable to resolve reference to item parameter.webutil config

Hi.
I have one form(10G) that's using webutil and the system returns this message, but I have others forms that's works fine.
I just copied all objects of webutil of one form that's ready works to this new form.
Someone already had this problem.
Best regards.

HI, when you copied the objects, did you drap the object group WEBUTIL to the new form's Object Group? If you did that you should have all the components that webutil require. oh. minus the most important one..webutil.pll :-)

Cannot find class java/lang/Thread

I'm getting this error trying to compile a program that I'm writing in java. Its a very simple program just to get me back to basics. Any ideas as to how I can fix this problem??

Extracted from Sun's website,
* Error Message: "Exception in thread NULL" or
"Unable to initialize threads: cannot find class java/lang/Thread"
If you are getting one of these fatal error messages when running java,
javac, or appetviewer, you should check your CLASSPATH environment variable.
It may list "c:\java" or the "classes" directory from an older release. You can either unset the CLASSPATH variable, or set it to
include only the latest version of the Java platform class library. For example:
C:\> set CLASSPATH=.;C:\jdk1.1.8\lib\classes.zip
This will make sure that you are using the correct classes for this release.

I downloaded an Adobe file from my email but cannot find it on my hard drive or in recycle bin - it's in downloads but am unable to open from downloads - how can I recover the file?

I downloaded an Adobe file from my email (service provider is MWeb) but now cannot find it on my hard drive and it's not in the recycle bin. It does, however, appear in Firefox downloads but I'm unable to open it from there. How can I recover the file?

Thanks Rob.
I actually had no clue what the core problem was caused by. So it's Windows itself...that helps some.
I'll resubmit there. It might actually have saved time for it to simply have been moved to there instead of off-topic, though I suppose you have to follow protocol.

I am unable to call up a folder from my documents files in pages. I haven't accessed it in a while but did not delete it and now cannot find it either through finder or a search of all saved documents. Not in my trash either. Where did I hide it?!?

I am unable to locate a folder in my document files in Pages. I haven't accessed it in several months and now cannot find it in the docs and folders when I go to "open an existing file ...", in finder, or the list of all saved docs. Can anyone suggest where I might have succeeded in hiding it? thanks!

Try Find Any File (also available in the Mac App Store). This will find hidden & invisible files as well as those in the various Libraries.
