Programically display/undisplay picture control (signature) in C#.

[KenM]

I would like to programically display a picture control (signature jpg) in C#
managed code when the signed in user checks a box (authorized) or undisplay
it if the box is not checked. InfoPath2007 pls. Thnks.

You can use conditional formatting to programmatically show/hide a picture
control just like you can do the same thing to disable a control (see
http://www.bizsupportonline.net/bro...ally-enable-disable-control-infopath-form.htm).

Thank you.

Now I notice that when the picture becomes enabeld you can still see the
control box it belongs in and then when enabled it forgets what the path was.
I'll start looking into that now.

Got more clues ? thanks.

Well, I tinkered around with it and the control doesn't actually get disabled.

But, I did learn how to create and change the picture, or make it null.

//look at an original picture, copy the value in VS
string fieldValue = MainDataSource.CreateNavigator().SelectSingleNode(

"/my:myFields/myicSignaturePicture",NamespaceManager).Value;

//Set the value of the picture, paste in the value you copied above in
"A_Bunch_Of_Picture_Bytes_Here" , and you'll see it.

XPathNavigator domNav = MainDataSource.CreateNavigator();
domNav.SelectSingleNode("//myicSignaturePicture",
NamespaceManager).SetValue("A_Bunch_Of_Picture_Bytes_Hereâ€);

A hack I spose and Doesn't really disable the control, but may be good
enough for now.
