Does StreamWriter drop leading tabs? 1

[IlyaRabyy]

Colleagues,
Here's what's happening: I, the Program, read a "truncated" XML file which I need to format and write back N times.
Formatting code:

' Add 4 Tab chars in front of every line 1st:
lsBlock = lsBlock.Replace(vbCrLf, vbCrLf & Replicate(Chr(9), 4))

' The starting tag <CheckDetail> - move it 1 tab to the right
lsBlock = lsBlock.Replace(Replicate(Chr(9), 4) & "<CheckDetail>", Replicate(Chr(9), 3) & "<CheckDetail>")
' The ending tag </CheckDetail> - move it 1 tab to the left:
lsBlock = lsBlock.Replace(Replicate(Chr(9), 4) & "</CheckDetail>", Replicate(Chr(9), 3) & "</CheckDetail>")

Dim loStreamWriter As New StreamWriter(tcFileOut, True)

'Add compound section's starting tag
loStreamWriter.Write(Replicate(Chr(9), 2) & "<CheckDetails>" & vbCrLf)

Then the For-Next cycle to write the whole block these N times - nothing interesting, so I skip it here, and I stop at the moment after the Stream is filled out.
So far, so good: note that, at the break point, the lcBlock in the Locals does have these leading Tabs.

But when I open the output file...

This bloody <CheckDetail> tag is written w/o those leading Tabs!

Hence the question in subject.
OR
Do I do something wrong?
Please advise.

TIA!

Regards,

Ilya

Before we proceed ... i'm assuming that Replicate is essentially an alias for strdup

The only way I can almost replicate your problem is if the first character(s) in lsBlock at this point in your code

' Add 4 Tab chars in front of every line 1st:
lsBlock = lsBlock.Replace(vbCrLf, vbCrLf & Replicate(Chr(9), 4))

are not vbCrLf

Bleen! (T's in Russian , you don't wanna kno...)
How stupid this old senile fool me could be!
The opening tag <CheckDetail> starts from pos. 1, and of course the line

lsBlock = lsBlock.Replace(Replicate(Chr(9), 4) & "<CheckDetail>", Replicate(Chr(9), 3) & "<CheckDetail>")

does nothing!

Thank you, colleague! U R Z Man!

Problem resolved, case is being closed.

Regards,

Ilya

Блеен - I know it as a very tasty 'pancake'

There is a great need for a sarcasm font.

Actually, "pancake" in Russian is "блин" (I write "bleen" in order for Anglophones to pronounce it properly), but it's also euphemism for the Russian cursing word as expression of utmost disappointment.
Just FYI.
