View 6 RepliesI am using a RichTextBox control on my form. I want a small code which can detect if any image has been inserted in the rtb or not. (IDE VS 2008)
For e.g. user can just type some text or insert image also (Ctrl + V). Now if we select an image then we can get the type but I want a code which scans contents of rtb and gives me a true if an image is inserted or false if there is none.
I already have the setting in Outlook to prevent automatic downloading of images but I still receive e-mail junk mail containing stationary. There is even a setting that prevents all images but that is the problem: It does it to ALL images.I would like to trap and move all messages with any kind of image in it and send it to a junk-mail folder. Someone told me that I might do it with a plug-in or an add-on and that it might be able to do this in VB.
