I have a few reports which my customer wants to print through the Preview option. The problem is, that these reports need the CurrReport.Preview function for logging data. But you cannot use this function if you want to print the report.
Is there a possibility to get into the trigger, after the print button in the page preview has been clicked?
Edit to specify: With logging data I mean first the real logging about the prints and secondly options like archive data and other stuff like this.
CurrReport.Preview: http://msdn.microsoft.com/en-us/library/dd301398.aspx
One option would be to call the Report again using REPORT.Run(Report::"Name Of Report",...) and apply the filters that were used on the initial report.
If it's an intense report it may not be practical (because it has to be run twice), but there are parameters to make the report print automatically;

I am currently trying to migrate Forms' Applications developped ten years ago to Oracle Apex. For some context, the database in which Forms applications are currently running is the Oracle EE 6i, and will be soon upgraded to the 12.2g, hence the need for migration. The data stored within the tables is to big to migrate (like 4To) so we need an alternative to Forms, but we cannot change the DB, and cannot keep Forms (which is let's be honest, outdated a little). I am currently on Oracle XE for my tests and on Apex 20.2.0.00.20 to start my migration (before upgrading).
The thing is, I have some issues with how Apex and Forms are working differently.
I am really blocking on the following issue since my migration:
In Forms, it was really easy to change the color of a button for exemple by calling a Forms method in a certain way depending on a condition (for exemple a SELECT return). Here, in Apex, I am trying to do the same.
I know that there are ten other ways of doing the same, with JS for exemple which I already succeedly do, but when I tried to create my second appplication I realised that compared to Forms, Apex cannot reference/generalise parts of the code(or applications) for different applications (and certainly not for different workspaces). So Javascript is a good solution but not as efficient as PL/SQL which is easier to generalise and will (in my opinion) use less exchange between the db and the client, since stored on the db.
That is why I decided to rely on PL/SQL Stored Procedure which will be specified in the database and called directly in each application where I need the process/computations.But I cannot find the same as in Forms, with my graphical methods helping me do what I need.
I am open to alternative of PL/SQL package/procedure/function if it can keep the same propreties (generalisation and minimum echange between client and db). These are important point since I have around 200 applications to migrate, starting with what we can call 'brick' which will compose the other simpler applications.
Btw: CSS is an option I studied, like HTML with PL/SQL dynamic content but I read that it was either not simple enough to integrate, or that it could be deprecated, so if it is the solution you are using, I could use a really detailled explaination or an exemple.
To give you an instance:
I click on a button triggering a PL/SQL stored procedure
Procedure checks some conditions in the db (like if a process is currently running)
PL/SQL update a table, change a variable in procedure and returns 'green'
The button becomes green, a message is displayed ('You have permission to do this!')
PS: if there are Apex Method modifying the graphical aspect, could I have a documentation ?
Thank you a lot for helping me resolve this issue, I have been stuck for days...
I tried Javascript bu the generalisation was too much a problem. I tried the HTML injecting but didn't work, I tried updating CSS but was not what I expected. I tried different PL/SQL method but couldn't find a way to connect PL/SQL with Apex/CSS/HTML...
It takes a bit of getting used to how APEX works, but everything can be done and once you get up to speed, you'll find there pretty simple ways to get things done. To achieve what you describe, this is what you'd do.
Create a dynamic action on click of button
Add the following actions to the dynamic actions
an action of type "execute pl/sql". This is your "Procedure checks ...". In this pl/sql code you can set page item values (make sure to reference those in "items to return" so the new values is set in the session. There is no reason to have 2 different pl/sql procedures, you can just put them in 1 block. This procedure would return the "green" - but more about this later.
an action to add a class to the button under certain conditions.
Note that the "green" is not something you should decide. In apex, there are a lot of layout modifier classes pre-defined. In your case, it makes sense to use the "success" modifier (which happens to be green).
To check how you want the button to look, there is a tool called the "button builder", you can use that to see what classes you should add/remove to change the look of the button.
Note that 20.2 is not a recent version. It was released in 2020. Since then 4 more releases have been made available: 21.1,21.2,22.1 and 22.2. It is advised to be on the latest version.
Here is a basic example. I have a page with a select list (P117_SELECTLIST), a hidden item to hold the button status (P117_BUTTON_STATE) and a button (MYBUTTON). The select list has 2 static values:
The dynamic action for serverside code is :
Note the items to submit and return values. P117_SELECTLIST is submitted so the pl/sql process picks that up from the client and P117_BUTTON_STATE is returned to the client so it is available for any future use.
Then I have 4 classes to set the button style. One to add success class, one to remove success class, one to add warning class, one to remove warning class. Below is the first one. The only think different in those 4 actions in the class name and the client condition. It can probably done with javascript directly as well with only 1 action.
I'd strongly suggest to update the db version to a version that supports the latest version of apex. It will save you a lot of development worries. Most people of forums only have the latest version available.
I would like to display some info on the screen ... which will disappear.
Example : an Uiview is displayed for the first time to an user (or feature never used by the user). I would like to display on a screen a label or an image to explain how to use this new feature. After that it will disappear ...
If this functionality has already been used by the user, the message is ofcourse not displayed.
example of message --> to add a gamer, press +
How to do that ? a lot of apps have this kind of help.
thanks
What you have to do is actually very simple : have a persistent variable, and change its value. Each time the user could see the help popup, you check the value of the variable you stored persistently. If this variable indicates that the user have already seen the help, you don't display it again. Otherwise, you show it. Simple example:
let helpSeen: Bool = getVarFromPersistent()
if helpSeen == false {
// DISPLAY THE HELP MESSAGE OR POPUP
setHelpSeenVar(true)
}
Where getVarFromPersistent() and setHelpSeenVar() are function you could create to respectively retrieve the variable from the persistent data and set the variable in the persistent data.
Now, you have to figure out how to use persistent data. You can have a look at CoreData, that is provided by Apple and "ready to use" in Xcode. You've probably already seen the use core data tickbox when you create a project.
Third party libraries exists as well like RealmSwift, who reached version 1.0 recently.
I'm not an expert, but I think Realm is simpler to use than Core Data. The technology used by the two libraries could be different though, maybe someone else could tell you more about it. Anyway, you will find a lot of article about Realm and Core Data on Google.
I have several Birt Reports that I am trying to set up to run on a cron job that will email pdfs of the reports every morning. Everything is working fine as far as the generation and emailing goes; the only issue I am stuck with is this: if there is nothing to report, a pdf with just the report title is generated and emailed (a blank report, basically). I'd like to stop this report from being generated at all, so i can skip the emailing, if the pdf file does not exist.
I have been all over Google for two days now, and the closest I can find is this: http://www.eclipse.org/forums/index.php/t/458779/ in which someone was trying to solve a similar problem and received a push in the right direction, but not a complete solution.
It appears as if this can be done during the beforerender script... but how?
I know I need to:
set a persistent global variable in the oncreate if there is indeed data to report.
get the persistent global variable in the beforerender script.
send the magic don't generate report command.
I'm doing all of generating and emailing from a php script, not Java, so I can't send commands like IEngineTask.cancel() (or can I???)
Yes, I know I can make a row in the report that says "No data to report", but that's not what my users want.
And yes, I could query the database outside of the report to determine if there is valid data to report or not, but i'd prefer not to.
And maybe I could even open and read the pdf, programmatically to see if there is anything there, but that sounds like more of a hassle than it's worth...
So, how do I do this?
Thanks.
My answer is a little bit late, but I'm doing it like this in a framework that is working for hundreds of reports, probably it could be simplified for a single report:
Note that all the code is written from memory (not copied from our framework), so maybe it contains some errors.
Add an external Javascript file myframework.js to your report.
In this file, define an object myframework like this:
if (myframework == undefined) {
myframework = {
dataFound: false,
afterReport: function() {
// Write it to the appContext.
// Using Java, you could read it after the
// runAndRenderTask is done.
reportContext.getAppContext().put("dataFound", this.dataFound);
// But since you probably cannot the context
// (don't like coding Java?), the report has to
// tell it to he world some other way...
var txt = "dataFound=" + (dataFound? "true": "false");
var fw = new java.io.FileWriter("c:\\reportcontext.out");
fw.write(txt);
fw.close();
}
};
}
Add the JS file to your report's resources.
In your report, at a place where you decide that the report has found something (e.g. typically in a data set's onFetch event), tell the framework so by calling
myframework.dataFound = true;
In the reports's afterFactory or afterRender event, call
myframework.afterReport();
Then your report should create an output file c:\reportcontext.out which contains the information you need.
We have two forms so far, and need to switch from window1 in from1 (which is login screen) to windowX in formX using button (trigger code below):
begin
show_window('windowX');
go_block('some_block_in_formX');
end;
This gives error FRM-41052: Cannot find Window: invalid ID
So question is, should I add formX into show_window parameter in certain way or is there another approach? Thank you.
Please note, that forms are in different files.
that forms are in different files.
If the forms are different files, you need to call the other form using open form/call form/newform - whatever suits your needs.
show_window/go_block sequence can be used only when you're moving to different windows/blocks of the same form - and the error message
error FRM-41052: Cannot find Window: invalid ID
is complaining that it can't go to that Window because it's in a different form.
Each form effectively has a private namespace for all its windows, blocks, items, etc - and your code always runs within the context of a single form.
To solve this, you'll need a form parameter, plus some code in the other form, e.g.:
in formX, add a parameter ACTION
in form1, pass the value 'XYZ' to ACTION
in formX, in the WHEN-NEW-FORM-INSTANCE trigger, check if :PARAMETER.ACTION = 'XYZ', and if so, do your show_window and go_block. Copy the same code to your WHEN-WINDOW-ACTIVATED trigger.
Of course, you'll need to think about the name of the parameter (e.g. ACTION) and value ('XYZ') that will make sense to people maintaining your forms in the future.
I am new to vb6. I am working to create the invoice generation application. I am using data report to show the generated invoice.
The step by step working of process is:
Entering the data in to Invoice and ItemsInvoice tables.
Then getting the maxId using (Adodc) from the data base to show the last generated Invoice.
Then passing the max Id as parameter to the data report which is showing the invoice according to the invoice id.
It is working fine when I first time generate invoice. Now for 2nd invoice without closing application I am getting a blank data report. For data report I am using dataenvironment.
I am guessing the reason the data report is blank is because there was no record for that Id, but actually the record is inserting in the database.
What is going wrong?
I'm not sure how your data set is getting configured, but it sounds like you have a single record in the data and aren't reloading it properly. If your report is manually moving through the recordset and only showing info based on the ID parameter you are passing it and then using the same recordset for the second report, you probably just need to MoveFirst on the recordset to put it back at the beginning.
Load the data environment and refresh the data report.
I am also generating report in the similar fashion. I faced this problem. Here's the solution
Load DataEnvironment1
With DataEnvironment1
'Command1 is the command added to data environment where you fire query or
'set it to point to a table
If .rsCommand1.State <> 0 Then .rsCommand1.Close
.Command1 maxid 'parameter you pass to the recordset
End With
DataReport1.Refresh
DataReport1.Show
Thats it!
You are done. I m sure it will work. Do tell me if it doesn't.
I don't know if the answer will still bother you, but if someone else have the same problem here is a example of how the problem works:
Imagine that there is a gate and a guard looking who is entering, when the first person (the first invoice) comes, the guard registers him, opens the gate (This is the event "Load DataEnvironmet") and then lets the guy pass. The guard believes that no one else would come and lets the door open (the instruction believes that the DataEnvironment ends and the value EOF becomes True), but when the second guy comes (the second invoice) the guard can't ask him who is (has, again, the value and lets it pass without registering him (this is the reason why the second invoice, and subsequent in while invoice would come blank). The solution is to close the gate ("Unload DataEnvironment") after a guy passes (After showing the data report).
The solution is the code given from Sangita above, but just before ending the sub you need to unload the DataEnvironment you were working on.
For me, it works. Sorry if the answer is not what you were looking for (and also if someone else can't understand what I'm writing, my English isn't very good). Just in case I will write the code with the solution
Load DataEnvironment1
With DataEnvironment1
If .rsCommand1.State <> 0 Then
.rsCommand1.Close
End If
.Command1 Value(ID)
End With
DataReport1.Refresh
DataReport1.Show
Unload DataEnvironment1
Try a refresh method like data1.recordset.requery or
Data1.refresh. This should work if you use data controls.
