Value not in Combobox Formfield

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

Hello,I have a given PDF File, which contains a Combobox into a Formfield. By using Adobe Reader or so the user can select an item. The Formfield has the name "84.0". and the Elements "B" , "E" and "K1". If I try to write a Value into the Combobox Formfield

QP.SetFormFieldValueByTitle("84.0", "B")

the field remains empty.
Is that way the right one for accessing Combobox designed Formfields?

Thanks for helping.

Tom

	That should work but I would need to see the PDF before making further comments as the display values can be different from the stored values. You could try the following code that should list the possible values for (int i = 1; i <= QP.FormFieldCount(); i++) { string title = QP.GetFormFieldTitle(i); string s = QP.GetFormFieldValue(i); int type = QP.GetFormFieldType(i); string txt = String.Format("{0}: Type={1} : Name={2} : Value='{3}'\n", i, type, title, s); OutputTxt.AppendText(txt); if (type == 3 \|\| type == 4 \|\| type == 5) // checkbox, radio, choicebox { int sc = QP.GetFormFieldSubCount(i); for (int j = 1; j <= sc; j++) { string sfn = QP.GetFormFieldSubName(i, j); OutputTxt.AppendText("Subfield" + j.ToString() + " : " + sfn + "\n"); string sn = QP.GetFormFieldSubName(i, j); // QP.SetFormFieldValue(i, sn); } } }

	Hello AndrewC, indeeed I developed a similar codefragment for testing whether there is a combobox. But I failed when I tried to write a value into the combobox. After I translated the c code into vb.net maybe I can report some more. Thanks Tom

	Hello AndrewC, i solved the problem. Here is my little code While (TotalFormFields > 0) Dim titel As String = QP.GetFormFieldTitle(TotalFormFields) Dim typ As Integer = QP.GetFormFieldType(TotalFormFields) If titel = "84.0" Then If typ = 5 Then QP.setformfieldvalue(totalformfields,"E") ' works very wellQP.SetFormFieldValueByTitle("84.0", "E") ' does not work (I dont know why) End If End If QP.FlattenFormField(TotalFormFields) QP.DeleteFormField(TotalFormFields) TotalFormFields = TotalFormFields -1End While Tom

	Sorry had to correct my last post. This code produces only empty Formfields, because the FlattenFormField and DeleteFormField kills the Value. Bythe way, the QP.SetFormFieldValueByTitle works also with comboboxes, but one can only write values into the combobox which are valid items of itself. For example B1 is not a valid item, so the Combobox remains empty. Any solutions for the FlattenFormField and DeleteFormField problem? kind regards Tom

	FlattenFormField by definition deletes the FormField so you don't need to call DeleteFormField. Can you try QP.UpdateAppearanceStream(TotalFormFields); before you call FlattenFormField. I suspect the formfields don't have appearance streams. When a Fieldname contains a '.' dot character it actually a parent + child where '84' is the parent and '0' is the child field name. Parents can have multiple children. I haven't tested this

	Unfortunately the QP.UpdateAppearanceStream(TotalFormFields) results in completly empty comboboxes without any content. I had another solution. I excluded all Formfields with Formfieldstype = 5 from the flattening. While (TotalFormFields > 0) Dim typ As Integer = QP.GetFormFieldType(TotalFormFields) If Not typ = 5 Then 'QP.UpdateAppearanceStream(TotalFormFields) QP.FlattenFormField(TotalFormFields) End If TotalFormFields = TotalFormFields - 1 End While That works so far. While not using the Deleteformfield Command the PDF Viewer (lets say Nitro or Adobe) ask for "Saving changes Yes/No/Cancel". Ingo gave this tip. " Hi Tom! Flattened or not ... there are still fragments from a form type pdf inside the content and acrobat is searching for it and gives you the warning message. Cheers and welcome here, Ingo " Thats a bit confusing. Tom
