_FileWriteToLine fails on empty line. Why?

Recommended Posts

Mr. Analogy

This script fails:


_FileWriteToLine ("C:\temp\claytest.txt",1, "clay's new text",true)
; this won't write if the file is empty

;returns error 

1 - File has fewer lines than $iLine


I've also tried writing to line 0 "then get error 4 : line is invalid.

Mr. Analogy,

This was a design decision not to allow the UDF to write to non-existent lines. However, the next release will feature an updated version of the function which will give the user the option to increase the file size to allow the line to be written.



Any of my own code posted anywhere on the forum is available for use by others without any restriction of any kind._______My UDFs:


ArrayMultiColSort ---- Sort arrays on multiple columns
ChooseFileFolder ---- Single and multiple selections from specified path treeview listing
Date_Time_Convert -- Easily convert date/time formats, including the language used
ExtMsgBox --------- A highly customisable replacement for MsgBox
GUIExtender -------- Extend and retract multiple sections within a GUI
GUIFrame ---------- Subdivide GUIs into many adjustable frames
GUIListViewEx ------- Insert, delete, move, drag, sort, edit and colour ListView items
GUITreeViewEx ------ Check/clear parent and child checkboxes in a TreeView
Marquee ----------- Scrolling tickertape GUIs
NoFocusLines ------- Remove the dotted focus lines from buttons, sliders, radios and checkboxes
Notify ------------- Small notifications on the edge of the display
Scrollbars ----------Automatically sized scrollbars with a single command
StringSize ---------- Automatically size controls to fit text
Toast -------------- Small GUIs which pop out of the notification area

@Mr. Analogy
If you want to write in a specific line, I would suggest you to write some blank text, like:


FileWriteLine($hFile, "") ; This, will make the first line as "non-empty", so you can proceed with _FileWriteToLine()

Then, If you want to write at line 1 some text like what you posted, you can use _FileWriteToLine.
Let us what do you think about :)

    By my knowledge, I can help someone else, and "that someone" could help in turn another, and so on.
