When I posted Method of the Day: AppendHotspot, people responded with surprise that one method could be good for so much. I thought that it would be good to show another mild mannered method which becomes a supermethod when you fully understand it, the ReplaceText method.
It may be hard to imagine just what the ReplaceText method might do besides replace text, but that is why I am writing this. To follow the format from the last post, here are recent questions for which the answer is the ReplaceText method.
It may be hard to imagine just what the ReplaceText method might do besides replace text, but that is why I am writing this. To follow the format from the last post, here are recent questions for which the answer is the ReplaceText method.
Q. Can I search for a string in a rich text field and replace it with another without hurting the format of the surrounding text and without losing images and tables?
A. Sure. Just use code such as:
Call rtitem.ConnectBackend(doc.Handle, "Body")
Set rtchunk = rtitem.DefineChunk("Everything")
Call rtchunk.ReplaceText(searchstring, replacestring)
Q. Can I search for a wildcard string in a rich text field and replace it?
A. Sure. Just use code such as:
Call rtitem.ConnectBackend(doc.Handle, "Body")
Set rtchunk = rtitem.DefineChunk("Everything")
rtchunk.TextWildCards = True
searchstring = "SRN*001"
replacestring = "OBSOLETE PRODUCT NUMBER"
Call rtchunk.ReplaceText(searchstring, replacestring)
Q. Can I change the URL inside a URL hotspot?
A. Sure. Just use code such as:
Call rtitem.ConnectBackend(doc.Handle, "Body")
Set rtchunk = rtitem.DefineChunk("Everything")
Q. Can I change hide-when formulas with Midas?
A. Sure. Just use code such as:
Call rtitem.ConnectBackend(doc.Handle, "Body")
Set rtchunk = rtitem.DefineChunk("Everything")
Call rtchunk.ReplaceText("@UserName", "@V2UserName", "HideWhen")
Watch for the new Hide-When sample sample db coming soon to the Midas Rich Text LSX sample dbs page.
Q. Can I change section titles?
A. Sure. Just use code such as:
Call rtitem.ConnectBackend(doc.Handle, "Body")
Set rtchunk = rtitem.DefineChunk("Everything")
Call rtchunk.ReplaceText("Sumary", "Summary", "NonText")
Q. Can I change action hotspots?
A. Sure. Just use code such as:
Call rtitem.ConnectBackend(doc.Handle, "Body")
Set rtchunk = rtitem.DefineChunk("ActionHotspot *")
Call rtchunk.ReplaceText("@UserName", "@V2UserName", "Formula")
URLs in hotspots? Formulas in action hotspots? Hide-when formulas? Pretty powerful for search and replace, don't you think?
