Variables from report

[dmajkic]

I looks like I can't get FastReport Varibale value.
I set variable, and display it in report, but I am unable to get it'value from PRG.
I need access to Variables from bOnBtnSendMail to perform my own Mail send to using HB sending engine which supports GMail.
Please find attached ultra-simple example. It should print "NEW VALUE", but it doesn't do that.

Hello,
The variable is inaccessible due two reasons:
1) Is not intialized when you first retrieve its value. The variable does not get any value until is started (printed).
I believe FR designer does not let you change any variable value. So you should set its value at least once by code.
BTW, that is what we do with Xailer:
::DeleteCategory('Xailer')
::AddCategory('Xailer')
::AddVariable('Application:cCompany', Application:cCompany )
::AddVariable('Application:cCopyright', Application:cCopyright )
::AddVariable('Application:cDescription', Application:cDescription )
::AddVariable('Application:cDirectory', Application:cDirectory )
::AddVariable('Application:cFilename', Application:cFilename )
::AddVariable('Application:cTitle', Application:cTitle )
::AddVariable('Application:cVersion', Application:cVersion )
Maybe you can do something similar to that.
2) FR uses the underscore to distinguish between categories and variables. So, do not put them.
This code worked on my side:
oRep:OnBtnGenPdf := {|o| MsgInfo(:GetVariable( "Test" )), .t. }

You can create and set variables via designer (click on Report->Variables...), or via script using Set() and Get() functions.
If you look at the bottom of the image, you can see what I am trying to do: Create Dialog, and return variable M.OK='TRUE' to harbour program.

I cant retreive value set in report dialog. I always get value set in prg.

SET via designer????? I could not find how, Please explain. BTW your _TEST variable was not initialized.
Cita:or via script using Set() and Get() functions.
The variable DOES NOT RECEIVE A VALUE UNTIL THE REPORT IS STARTED. WHEN YOU RETRIEVE THE VAR VALUE YOUR SCRIPT IS NOT RUNNED YET. It worked for me because I retrieve the var value on the OnBtnPdf event.

You do not need to create, nor to set its value, if already exists on your fr3 file.

No need to yell.
I initialize variable TEST in report designer.
Then on report create I change value (in PascalScript) to "NEW VALUE". That "NEW VALUE" is displayed on the report preview.
I would like to retrieve that "NEW VALUE" to Harbour app.
To do that I set block on bOnSendMail which uses GetVariable(), and simple print to screen.
I have a preview and "NEW VALUE" on screen.
Then I clik on Export->Email...
Retrieved value is not "NEW VALUE", but old value set in designer.
Attached is, perhaps a bit better, example without underscore on TEST, which demonstrates what I wrote.

This issue remains in new FRX version.
Just for reminder, when example above is compiled and started:
* Report is shown with "NEW VALUE" displayed on report preview
* Click on Export->Email...
* This should print on terminal "NEW VALUE", but it doesn't (instead prints old value)
It looks like report values are not retreived from FR Report object, but from some kind of
internal FRX cache which is not updated after creation.

This code is working fine here:
WITH OBJECT TFastReport():New()
:Create()
:cFilename := ".Reportse2.fr3"
MsgInfo(:GetVariable( "Test" ))
:OnBtnGenPdf := {|o| MsgInfo(:GetVariable( "Test" )), .t. }
:DesignReport()
:End()
END WITH
