editing html string having text and several images using regex

I am new to this forum and hoping to get some help.
I have a an HTML string having text and several base64 images.
I need to loop through all image tags adding a slash / before
the closing tag > so that each image ends with /> and return
a new html string with the changes.
so each
<IMG src="data:image/png;base64,iVBORw0KG....">
should then be
<IMG src="data:image/png;base64,iVBORw0KG...."/>
I am not versed with html and I am wondering how to do it
(using regex?).
Here is some pseudo code:
Function GetSourceImges(Sourcehtml As String) As List(Of String)
Dim listOfImgs As New List(Of String)()
'use regex to find image tags
'Return list of base64 image tags
End Function
For each image in list
insert a slash appropriately
next
Reconstitute a new html string with edited images
Thanks

Map all "IMG" tags using LINQ and use their indexes as an anchor to fix the missing "/" characters. please see my comments inside the code.
Sub Main()
Dim htmlstring As String = "<IMG src=""data:image/png;base64,iVBORw0KG....""> " & vbCrLf _
& "<img src=""data:image/png;base64,iVBORw0KG...."">" & vbCrLf _
& "<p>blahblah</p>" & vbCrLf _
& "<IMG src=""data:image/png;base64,iVBORw0KG...."">" & vbCrLf _
& "<p>blahblah</p>"
' find all indxes of img using regex and lambda exprations '
Dim indexofIMG() As Integer = Regex.Matches(htmlstring, "IMG", RegexOptions.IgnoreCase) _
.Cast(Of Match)().Select(Function(x) x.Index).ToArray()
' check from each index of "IMG" if "/" is missing '
For Each itm As Integer In indexofIMG
Dim counter As Integer = itm
While counter < htmlstring.Length - 1
If htmlstring(counter) = ">" Then
If htmlstring(counter - 1) <> "/" Then
' fix the missing "/" using Insert() method '
htmlstring = htmlstring.Insert(counter, "/")
End If
Exit While
End If
counter += 1
End While
Next
Console.WriteLine(htmlstring)
Console.ReadLine()
End Sub

Surprisingly it works with the console app but doesn't when I view it on a richtextbox as in btnEditHTML method below. The generated pdf has only one red dot and not two.
Can't say why.
I must say you have been very helpfull.

I highly recommend just using AngleSharp to parse the HTML, edit the document if required, and save it again.
There are many posts on here about why trying to parse HTML with regular expressions is a bad idea.
var doc = new HtmlParser().Parse(html);
As you aren't actually changing the HTML content, just fixing up the tags, your should be able to just parse it and save it with no changes to fix the tags.

.NET & Word - How to Convert PlainText to MergeField in Document

i am using Visual Studio .NET (VB)
So if you have a solution in C#, just go here first (http://converter.telerik.com/)
I have a document with text, and an array of words to replace:
I need to replace the plaintext and substitute with actual mergefield
Dim replacements(,) As String =
New String(,) {{"[firstname]", "$Field.FName"},
{"[lastname]", "$Field.LName"},
{"[addr]", "$Field.Addr.St"},
{"[city]", "$Field.City"}}
Dim dotXLoc "c:/test/result.dotx"
Dim Fileformat As Microsoft.Office.Interop.Word.WdSaveFormat = Word.WdSaveFormat.wdFormatXMLTemplate 'SAVE AS DOT
Dim wordApp As Object = New Microsoft.Office.Interop.Word.Application()
Dim currentDoc As Microsoft.Office.Interop.Word.Document = wordApp.Documents.Open(dotXLoc)
' Get bounds of the array.
Dim bound0 As Integer = replacements.GetUpperBound(0)
' Loop over all elements.
For i As Integer = 0 To bound0
' Get element.
Dim FieldFind As String = replacements(i, 0)
Dim FieldReplace As String = replacements(i, 1)
'<<< CODE HERE TO REPLACE TEXT WITH MERGEFIELD >>>
Next
currentDoc.SaveAs(dotXLoc & " v2.dotx", Fileformat)
currentDoc.Close()
wordApp.Quit()

Here is the end result
Public sub main()
Dim rtfLoc = "c:/temp.rtf"
Dim dotXLoc = "c:/temp.dotx"
Dim Fileformat As Microsoft.Office.Interop.Word.WdSaveFormat = Word.WdSaveFormat.wdFormatXMLTemplate
Dim wordApp As Word.Application = New Microsoft.Office.Interop.Word.Application()
Dim currentDoc As Microsoft.Office.Interop.Word.Document = wordApp.Documents.Open(rtfLoc)
TextToMergeField(currentDoc)
currentDoc.SaveAs(dotXLoc, Fileformat)
currentDoc.Close()
wordApp.Quit()
End Sub
we call TextToMergeField(currentDoc) from the main function
this way we can loop through multiple documents and replace all instances
Private Sub TextToMergeField(ByRef currentdoc As Word.Document)
Dim rng As Word.Range
Dim replacements(,) As String =
New String(,) {{"[firstname]", "$Field.FName"},
{"[lastname]", "$Field.LName"},
{"[addr]", "$Field.Addr.St"},
{"[city]", "$Field.City"}}
Dim bound0 As Integer = replacements.GetUpperBound(0)
currentdoc.Activate()
For i As Integer = 0 To bound0
rng = currentdoc.Range
With rng.Find
.Text = replacements(i, 0)
Do While .Execute(Replace:=WdReplace.wdReplaceOne)
currentdoc.Fields.Add(rng, WdFieldType.wdFieldMergeField, replacements(i, 1))
Loop
End With
Next
End Sub

The problem is that you have included double quotes (") inside your string literal. The first double quote inside the string is taken to mean the end of the string. It happens to be followed by a single quote which indicate the start of a comment. If you include a double quote inside a string literal, you need to have two of them. Here is the corrected statement (I split it over three lines for readability).
oExcelsheet.Range("f2").Formula = "=IF(LEN(A2)=2,(CONCATENATE(""'00000"",A2))," _
& "IF(LEN(A2)=3,CONCATENATE(""'0000"",A2),IF(LEN(A2)=4,CONCATENATE(""'000"",A2)," _
& "IF(LEN(A2)=5,CONCATENATE(""'00"",A2),IF(LEN(A2)=6,CONCATENATE(""'0"",A2),A2)))))"

Convert code from c# to vb.net

I am using the below code in c# page. It's working fine. I am new for vb.net. I convert the same using online converter but i got error i can't understood that error. Please help me to do the same.
string StrInputParam = "TYPE:5#MOBILE:" + Mobile + "#PASS:" + Password + "";
string StrSPName = ConfigurationManager.AppSettings["SP_RED_USER_DETAILS"];
string[] ArrayVal = StrInputParam.Split('#');
StrSPName = Regex.Replace(StrSPName, #"\[(.+?)\]", m =>
{
string StrParamName = m.Groups[1].Value;
string StrParamValue = ArrayVal.Select(s => s.Split(new[] { ':' }, 2))
.Where(p => p.Length == 2)
.Where(p => p[0] == StrParamName)
.Select(p => p[1])
.FirstOrDefault();
return StrParamValue ?? "0"; // "0" instead of m.Value
});
Error:
Overload resolution failed because no accessible 'Replace' can be called with these arguments:
'Public Function Replace(input As String, evaluator As System.Text.RegularExpressions.MatchEvaluator, count As Integer) As String': Value of type 'String' cannot be converted to 'System.Text.RegularExpressions.MatchEvaluator'.
'Public Function Replace(input As String, evaluator As System.Text.RegularExpressions.MatchEvaluator, count As Integer) As String': Lambda expression cannot be converted to 'Integer' because 'Integer' is not a delegate type.......

You can use below code :-
Dim StrInputParam As String = "TYPE:5#MOBILE:" & Mobile & "#PASS:" & Password & ""
Dim StrSPName As String = ConfigurationManager.AppSettings("SP_RED_USER_DETAILS")
Dim ArrayVal As String() = StrInputParam.Split("#"C)
StrSPName = Regex.Replace(StrSPName, "\[(.+?)\]", Function(m)
Dim StrParamName As String = m.Groups(1).Value
Dim StrParamValue As String = ArrayVal.[Select](Function(s) s.Split(New () {":"C}, 2)).Where(Function(p) p.Length = 2).Where(Function(p) p(0) = StrParamName).[Select](Function(p) p(1)).FirstOrDefault()
' "0" instead of m.Value
Return If(StrParamValue, "0")
End Function)

Use below code
Dim StrInputParam As String = "TYPE:5#MOBILE:" + Mobile + "#PASS:" + Password + ""
Dim StrSPName As String = ConfigurationManager.AppSettings("SP_RED_USER_DETAILS")
Dim ArrayVal As String() = StrInputParam.Split("#"C)
StrSPName = Regex.Replace(StrSPName, "\[(.+?)\]", Function(m)
Dim StrParamName As String = m.Groups(1).Value
Dim StrParamValue As String = ArrayVal.Select(Function(s) s.Split(New () {":"C}, 2))
.Where(Function(p) p.Length = 2)
.Where(Function(p) p(0) = StrParamName)
.Select(Function(p) (1))
.FirstOrDefault()
Return If(StrParamValue, "0")
End Function)
Or try this code
Dim StrInputParam As String = "TYPE:5#MOBILE:" + Mobile + "#PASS:" + Password + ""
Dim StrSPName As String = ConfigurationManager.AppSettings("SP_RED_USER_DETAILS")
Dim ArrayVal() As String = StrInputParam.Split("#"c)
StrSPName = Regex.Replace(StrSPName, "\[(.+?)\]", m =>
{
Dim StrParamName As String = m.Groups(1).Value
Dim StrParamValue As String = ArrayVal.Select(s = > s.Split(New()
{
":"c
}
, 2))
.Where(p => p.Length = 2)
.Where(p => p(0) = StrParamName)
.Select(p => p(1))
.FirstOrDefault()
Return StrParamValue ?? "0"
}
)

There you go, I converted it for you:
Dim StrInputParam As String = "TYPE:5#MOBILE:" & Mobile & "#PASS:" & Password & ""
Dim StrSPName As String = ConfigurationManager.AppSettings("SP_RED_USER_DETAILS")
Dim ArrayVal() As String = StrInputParam.Split("#"c)
StrSPName = Regex.Replace(StrSPName, "\[(.+?)\]", Function(m) ' "0" instead of m.Value
Dim StrParamName As String = m.Groups(1).Value
Dim StrParamValue As String = ArrayVal.Select(Function(s) s.Split( { ":"c }, 2)).Where(Function(p) p.Length = 2).Where(Function(p) p(0) = StrParamName).Select(Function(p) p(1)).FirstOrDefault()
Return If(StrParamValue, "0")
End Function)

How to: Check if current user is member of ‘domain admins’

I need to verify that a provided username is a Domain Administrator in c#.
Any idea's on how to do this?

You can use WindowsIdentity to get the current user.
Then create a WindowsPrincipal with the WindowsIdentity.
And check WindowsPrincipal.IsInRole(WindowsBuiltInRole.Administrator)
Hope this can help you.
EDIT : I just see the ASP tag now... This link could help you, same thing but for ASP.
