Deleting All Images in TX Text Control .NET for Windows Forms
Removing all images from a document in TX Text Control .NET for Windows Forms requires using the FrameBaseEnumerator rather than a for-each loop. This VB.NET code sample obtains the enumerator from the Images collection, iterates through each image, and removes it individually.
In a recent blog entry, I showed how to remove all tables from the current document in TX Text Control .NET for Windows Forms. Today, I would like show the same with images. Like in the TableBaseCollection, images cannot be deleted in a for each statement. We have to use the specific enumerator that is responsible for images. In case of images, the FrameBaseEnumerator should be used.
The following VB.NET function removes all images in a document:
Private Sub removeAllImages()
Dim myImageEnum As TXTextControl.FrameBaseCollection.FrameBaseEnumerator = TextControl1.Images.GetEnumerator
Dim imageCounter As Integer = TextControl1.Images.Count
For i As Integer = 0 To imageCounter
myImageEnum.MoveNext()
Dim currentImage As TXTextControl.Image = myImageEnum.Current
TextControl1.Images.Remove(currentImage)
Next
