Handling a Word Processing control by programming
A Word Processing control can be handled by programming. To handle the Word Processing control, WLanguage proposes: This help page explains how to handle a Word Processing control by programming.
Caution: This documentation presents the last features of the Word Processing control. Make sure that all the necessary modules are updated. Handling the Word Processing control by programming Opening and creating a docx document in a Word Processing control To open an existing docx document by programming in a Word Processing control, you can: - assign the docx file to the Word Processing control. For example:
// Select a .docx file in the current directory
sFileName is string
sFileName = fSelect("", "presentation.docx", ...
"Selecting DocX files", ...
"Docx file (*.docx)" + TAB + "*.docx", "*.docx", fselOpen)
IF sFileName ~= "" THEN
// No selected file
RETURN
END
// Load the docx file
WP_MyDocument = sFileName
- use DocOpen.
For example:
WP_MyDocument = DocOpen("C:\Users\test\Documents\file.docx")
IF ErrorOccurred() THEN
Error(ErrorInfo())
RETURN
- use a Document variable and assign it to the Word Processing control.
For example:
MyDocument is Document
MyDocument = "C:\temp\presentation.docx"
WP_MyDocument = MyDocument
or:
MyDocument is Document
MyDocument = DocOpen("C:\Users\test\Documents\file.docx")
IF ErrorOccurred() THEN
Error(ErrorInfo())
ELSE
WP_MyDocument = MyDocument
END
Caution: only the files in docx format can be handled by the Word Processing control. Tip: To display an empty document in a Word Processing control, all you have to do is assign an empty string to the Word Processing control. Example:
// Create a blank document
WP_MyDocument = ""
Saving a docx document To save a docx document, all you have to do is use DocSave. Example:
// Choose the directory and the backup name
sFileName is string = fSelect(CompleteDir(fExeDir()),"presentation.docx", ...
"Selecting DocX files","Docx file (*.docx)" + TAB + "*.docx" , "*.docx", fselCreate)
// Save the file
DocSave(WP_NoName1, sFileName)
IF ErrorOccurred THEN
Error(StringBuild("The %1 file was not saved.", sFileName), ErrorInfo())
RETURN
END
Notes: - The content of Word Processing control can also be:
- DocToText is used to retrieve the document text.
- DocToImage is used to convert a document page into image.
This function is available from version 220052s (update module of Word Processing control applicable to WINDEV Update 1).
Performing a search in a document and modifying the search result To perform a search in a Word Processing document, all you have to do is use DocSeek. Example:
// Seeks "BEAUTIFUL" in the text
// Selects the first one found to change its color
arrFragments is array of docFragments = DocSeek(WP_NoName1, "BEAUTIFUL")
IF arrFragments..Count >= 1 THEN
// Position the cursor at the beginning of the first word found
WP_NoName1..Cursor = arrFragments[1]..StartPosition
// Calculate the selection length
WP_NoName1..SelectionLength = ...
arrFragments[1]..EndPosition - arrFragments[1]..StartPosition+1
// Modify the text color
arrFragments[1]..Style..TextColor = PastelRed
BREAK
END
// Seeks "BEAUTIFUL" in the text
// Selects the first one found to change its color
arrFragments is array of docFragments = DocSeek(WP_NoName1, "BEAUTIFUL")
IF arrFragments..Count >= 1 THEN
// Position the cursor at the beginning of the first word found
WP_NoName1..Cursor = arrFragments[1]..StartPosition
// Calculate the selection length
WP_NoName1..SelectionLength = ...
arrFragments[1]..EndPosition - arrFragments[1]..StartPosition+1
// Modify the text color
arrFragments[1]..Formatting..TextColor = PastelRed
BREAK
END
In this code, the docFragment variable corresponds to the text section containing the sought word, as well as its position in the entire text. Then, you have the ability to handle the fragment found. Handling the selection To handle the selection currently performed in a Word Processing control, you have the ability to retrieve this selection in a docFragment variable. The following code is used to change the color of selected text. Example:
// Change the selection color
// Get the current selection
MySelection is docFragment(WP_MyDocument, WP_MyDocument..Cursor, ...
WP_MyDocument..SelectionLength)
// Change the color
MySelection..Style..TextColor = PastelRed
// Change the selection color
// Get the current selection
MySelection is docFragment(WP_MyDocument, WP_MyDocument..Cursor, ...
WP_MyDocument..SelectionLength)
// Change the color
MySelection..Formatting..TextColor = PastelRed
The docFragment variable owns a specific constructor used to easily retrieve the selection. Adding text into a document Several methods can be used to add text into an existing document: - Inserting a fragment at requested position. Example:
// Insert a text at the end of document
frag2 is docFragment(WP_MyDoc, (Length(DocToText(WP_MyDoc) + 1)), 0)
frag..Text += "End text"
- Inserting a text from a given position with DocInsert.
DocInsert(WP_Document, WP_Document..Cursor, "My inserted text")
This feature is available from version 220052s (update module of Word Processing control applicable to WINDEV Update 1).
To add text into an empty document, you can: - use the direct assignment of control:
<Word Processing control> = "Text to insert"
Example:
WP_MyDocument = "I am the first sentence of this document."
- insert a fragment in first position. Example:
// sInitialText contains the text to insert
frag is docFragment(WP_MyDoc, WP_MyDoc..Cursor, 0)
frag..Text += sInitialText
- insert a text from position 1 with DocInsert.
DocInsert(WP_Document, 1, "My inserted text")
This feature is available from version 220052s (update module of Word Processing control applicable to WINDEV Update 1).
Several methods can be used to add text into an existing document: - Inserting a fragment at requested position. Example:
// Insert a text at the end of document
frag2 is docFragment(WP_MyDoc, -1 , 0)
frag..Text += "End text"
- Inserting a text from a given position with DocInsert.
DocInsert(WP_Document, WP_Document..Cursor, "My inserted text")
This feature is available from version 220052s (update module of Word Processing control applicable to WINDEV Update 1). - Adding a text at the end of document with DocAdd.
To add text into an empty document, you can: - use the direct assignment of control:
<Word Processing control> = "Text to insert"
Example:
WP_MyDocument = "I am the first sentence of this document."
- add the text with DocAdd.
- insert a fragment in first position. Example:
// sInitialText contains the text to insert
frag is docFragment(WP_MyDoc, WP_MyDoc..Cursor, 0)
frag..Text += sInitialText
- insert a text from position 1 with DocInsert.
DocInsert(WP_Document, 1, "My inserted text")
This feature is available from version 220052s (update module of Word Processing control applicable to WINDEV Update 1). Adding a page break into a document The following code is used to add a page break into a document:
// Add a page break
DocAdd(WP_NoName, Charact(12))
 Versions 24 and laterYou can also use the following constants to add the desired type of break to a document or fragment: - docColumnBreak: Adds a column break in a multicolumn section. If the section is not multicolumn, a page break is added.
- docLineBreak: Adds a line break.
- docPageBreak: Adds a page break.
- docParagraphBreak: Adds a paragraph break.
Example:
// Add a page break
DocAdd(WP_NoName1, docPageBreak + "Text on next page")
 New in version 24You can also use the following constants to add the desired type of break to a document or fragment: - docColumnBreak: Adds a column break in a multicolumn section. If the section is not multicolumn, a page break is added.
- docLineBreak: Adds a line break.
- docPageBreak: Adds a page break.
- docParagraphBreak: Adds a paragraph break.
Example:
// Add a page break
DocAdd(WP_NoName1, docPageBreak + "Text on next page")
- docColumnBreak: Adds a column break in a multicolumn section. If the section is not multicolumn, a page break is added.
- docLineBreak: Adds a line break.
- docPageBreak: Adds a page break.
- docParagraphBreak: Adds a paragraph break.
Example:
// Add a page break
DocAdd(WP_NoName1, docPageBreak + "Text on next page")
Versions 23 and laterManagement of bookmarks You have the ability to manage bookmarks in a Word Processing document. Some examples: - Adding a bookmark: Adds a bookmark named MyBookmark with the selected text.
doc is Document
doc <- WP_MyDocument
fragSelection is docFragment = WP_MyDocument..Selection..Fragment
doc..Bookmark["MyBookmark"] = fragSelection
- Deleting a bookmark: Deletes the bookmark named Bookmark1:
doc is Document
doc <- WP_MyDocument
Delete(doc.Bookmark, "Bookmark1")
- Listing the bookmarks: Lists the document bookmarks:
doc is Document
doc <- WP_MyDocument
FOR EACH uABookmark,BookmarkName of doc..Bookmark
Trace(BookmarkName) // Bookmark name
Trace(uABookmark..Text) // Bookmark text
END
- Inserting a text at the end of bookmark:
doc is Document <- WP_MyDocument..Value
// Find the bookmark position
fragmentBookmark is docFragment = doc..Bookmark["Bookmark 1"]
IF fragmentBookmark <> Null THEN
// Insert text at the end of bookmark
let nInsertionPosition = fragmentBookmark..EndPosition
// Actual insertion
DocInsert(WP_MyDocument, nInsertionPosition, "Text to insert at bookmark position")
ELSE
Erreur("'Bookmark 1' bookmark not found in the document")
END
New in version 23Management of bookmarks You have the ability to manage bookmarks in a Word Processing document. Some examples: - Adding a bookmark: Adds a bookmark named MyBookmark with the selected text.
doc is Document
doc <- WP_MyDocument
fragSelection is docFragment = WP_MyDocument..Selection..Fragment

FOR EACH uABookmark,BookmarkName of doc..Bookmark
Trace(BookmarkName) // Bookmark name
Trace(uABookmark..Text) // Bookmark text
END
- Inserting a text at the end of bookmark:
doc is Document <- WP_MyDocument..Value
// Find the bookmark position
fragmentBookmark is docFragment = doc..Bookmark["Bookmark 1"]
IF fragmentBookmark <> Null THEN
// Insert text at the end of bookmark
let nInsertionPosition = fragmentBookmark..EndPosition
// Actual insertion
DocInsert(WP_MyDocument, nInsertionPosition, "Text to insert at bookmark position")
ELSE
Erreur("'Bookmark 1' bookmark not found in the document")
END

// Actual insertion
DocInsert(WP_MyDocument, nInsertionPosition, "Text to insert at bookmark position")
ELSE
Erreur("'Bookmark 1' bookmark not found in the document")
END
Sequencing reports and Word Processing documents You now have the ability to sequence reports and Word Processing documents. To do so, iSequencingAddDoc must be used in addition to the standard functions for creating sequences of reports. For example:
MyDocument is Document = "c:\temp\generalconditions.docx"
iPreview()
// Add reports into the sequence
iSequencingAdd(RPT_Report1)
iSequencingAdd(RPT_Report2, 3)
// Add the general conditions in document format
iSequencingAddDoc(MyDocument)
iSequencingPrint()
For more details, see Sequencing reports.
