Easy C# to VB help with iTextSharp

Question

User993368333 posted

I have the following code Snipit that i'm working with using the iTextSharp DLL.  I've got the thing working fine, BUT, I had to change a 'var' type in my converted VB example code to string.  It works for everything that is text, but I can't get Checkbox values to set in the PDF document. 

 

'This was the C# Code

public static byte[] GeneratePDF(string pdfPath, Dictionary<string, string> formFieldMap)
    {
        var output = new MemoryStream();
        var reader = new PdfReader(pdfPath);
        var stamper = new PdfStamper(reader, output);
        var formFields = stamper.AcroFields;

        foreach (var fieldName in formFieldMap.Keys)
            formFields.SetField(fieldName, formFieldMap[fieldName]);

        stamper.FormFlattening = true;
        stamper.Close();
        reader.Close();

        return output.ToArray();
    }

 

I converted it to VB using: http://www.developerfusion.com/tools/convert/csharp-to-vb/

to get this:

Public Shared Function GeneratePDF(pdfPath As String, formFieldMap As Dictionary(Of String, String)) As Byte()
		Dim output = New MemoryStream()
		Dim reader = New PdfReader(pdfPath)
		Dim stamper = New PdfStamper(reader, output)
		Dim formFields = stamper.AcroFields

		For Each fieldName As var In formFieldMap.Keys
			formFields.SetField(fieldName, formFieldMap(fieldName))
		Next

		stamper.FormFlattening = True
		stamper.Close()
		reader.Close()

		Return output.ToArray()
	End Function

 

NOW, the line I changed because I dind't know the VB equivilant was:

For Each fieldName As var In formFieldMap.Keys
----I changed it to:
For Each fieldName As string In formFieldMap.Keys

I know that's cheating, but I didn't know what var was...it's not VariantType

SO, i'm hoping that's the reason I can't set checkboxes with code like this:

Neither of these work: (IE, the boxes are not checked)

        formFieldMap("intro_ckdeath") = "yes"
        formFieldMap("ck_3") = "1"

Where as:

        formFieldMap("clientname") = M_FullName

Works perfect.

I got the example code from:

Thanks everyone for the help, I appreciate it.

The VB equivalent to inferred typing - assuming you're not using an old version of VB - is just to leave the type off:

For Each fieldName In formFieldMap.Keys

David,

Removing the of type was valid.  But, unfortunitaly, it didn't solve the problem with iTextSharp no checking the text boxes. So I guess I was wrong to make the assumption that that was the cause.

 

This is the code i'm trying:

        formFieldMap("intro_ckdeath") = "yes"
        formFieldMap("ck_3") = "1"

I'm going to try a different PDF template, maybe mine is not made correctly in Acrobat for some reason.  Any other suggestions?

Ok, for anyone else who has this issue, here is the solution:

 

formFieldMap("intro_ckdeath") = "yes"  (DOESN'T WORK)

 

formFieldMap("intro_ckdeath") = "Yes" (WORKS)

 

Notice the capital 'Y" 

 

Thanks David for your CORRECT answer to the first question.  I was just wrong in what was causing it.
