The SubNames from QPL can be used to determine the correct values. According to the PDF specification "Off" should always be the off state.

Here is some code that attempts to turn on all Checkboxes on a form. You can modify this code to meet your needs.

QP.LoadFromFile("formfields.pdf", "");

for (int i = 1; i < QP.FormFieldCount(); i++)

{

int fType = QP.GetFormFieldType(i);

string fName = QP.GetFormFieldTitle(i);

int sc;

switch (fType)

{

case 1: // Text

QP.SetFormFieldValue(i, "ABDCEF");

break;

case 3:

case 4:

case 5:

sc = QP.GetFormFieldSubCount(i);

for (int j = 1; j <= QP.GetFormFieldSubCount(i); j++)

{

string value = QP.GetFormFieldSubName(i, j);

if (value != "Off")

QP.SetFormFieldValue(i, value);

}

break;

case 7: // Parent

break;

}

Hello,
The PDF Spec seems to show that the output can be whatever the designer of the form wishes to use.
There is no set value.
You will need to either control the source pdf files, or code for each variant you find.

I am processing pdf document from different origins, programmatically filling out form field values. The problem I have is filling out checkboxes. Possible variants that I came across are "1/0", or "Off/On", or "Yes/No".

My question is:

how to find what values makes checkbox field being "check" and "uncheck"?

There is an API function GetFormFieldDefaultValue that in case of "Off/On" will return "Off", but it is unclear if "DefaultValue" for checkbox is a value for "unchecked" or "checked" checkbox?
