I tried with Office 2010 & 2013 it gives following error
Run time error '-2147188160 (80048240)':
Presentation (unknown member): Invalid request. Saving as an HTML presentation is not supported in this version of Powerpoint.
It works in Office 2007 - there directly i can save as MHT or HTML format.
But my system installed office 2013 here it is giving error. I want try with 2010 or 2013.
Please suggest.

You can drive the save to MHT using automation. Basically, even though MHT isn't exposed via the save function in 2010 (not 2013 sadly) you can still get to it via VBA so you're going to have to do something like this:
Public Sub ConvertToMHT(ByVal FileLocation As String)
ActivePresentation.SaveAs FileLocation, ppSaveAsWebArchive
End Sub

Hello. I am a little confused.
I have this code:
Dim dv As New DataView(_DataSet.Tables(0))
dv.RowStateFilter = DataViewRowState.Deleted
For _irow As Long = 0 To dv.Table.Rows.Count - 1
If Not IsDBNull(dv!serial) Then
txtSerial.Text = (dv!serial).ToString
Dim strconnection As String = "Data Source=EASMAR-PC;Initial Catalog=Database Connection;Integrated Security=True;"
Dim _cn As SqlConnection = New SqlConnection(strconnection)
_cn.Open()
Dim cmd As New SqlCommand
cmd.CommandText = "Delete from tblCustomer where serial= " & (dv!serial).ToString
End If
Next
I am getting this error:
Conversion from string ?serial? to type
on this line:
If Not IsDBNull(dv!serial) Then
serial is an autoincremented integer in my database. So why am i getting this string error conversion?
Is there a logic reason for this?
I tried to replace the previous line by this one:
If Not IsDBNull(dv.Item("Serial")) Then
Still the same error

You're using the old VB6 syntax. What you're doing is wrong on at least a few levels. Not the least of which is that indexers (you For statement) are never Longs, but instead should be Integers. On top of that, you never use the indexer (_irow)!
It should read more like this:
For index As Integer = 0 To dv.Count - 1
DataRowView rowView = dv(index)
If Not IsDBNull(rowView("serial")) Then
' This next line is meaningless because you'll never see the textbox
' update on a per-row basis. You'll only see the changes made by the
' last iteration of the enclosing For/Next loop.
' Also, why are you even bothering to try to convert DbNull to a String??
txtSerial.Text = ...
' You should be moving this database Delete to it's own method.
' You should also be converting it to a parameterized query instead of
' using string concatenation to build the query.
' You also never execute to command, so nothing really happens here.
' The database connection string and connection open statements really
' should not be inside the For/Next loop.
End If

1. You haven't described your question/problem well
2. You've chosen the wrong forum, there is a separate forum for ASP.NET
3. Asking for code will only get your post and your profile reported and possibly removed
4. No one is going to write code for you or take the pain to find the code and email it to you
5. The only thing that you can expect to receive from this post is quite a good amount of spam.

Hi. I am coding a program (important: .NET 2 (3.5), C#) where i get input of GUIDs in various formats. On MSDN is documented, that it is possible to use
zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz
or zzzzzzzz-zzzz-zzzz-zzzz-zzzzzzzzzzzz
or {zzzzzzzz-zzzz-zzzz-zzzz-zzzzzzzzzzzz}
or (zzzzzzzz-zzzz-zzzz-zzzz-zzzzzzzzzzzz)
or {0xzzzzzzzz, 0xzzzz, 0xzzzz,0xzz,0xzz,0xzz,0xzz,0xzz,0xzz,0xzz,0xzz}}The goal is to produce a (hex)string of length 32 characters (for 16 bytes) regardless of input.
So I programmed and debugged and tested and looked ...
System.Guid test=new System.Guid("{2426186D-B96D-4656-9B65-15C727744643}");
System.Console.WriteLine(BitConverter.ToString(test.ToByteArray()).Replace("-", string.Empty));
What goes wrong? I expect to see "2426186DB96D46569B6515C727744643", but get
"6D1826246DB956469B6515C727744643". Please give advice. TIA Nicki.

Make sure the result from "ToByteArray()" is what you expect it to be.
Put that operation on a separate line, and place a breakpoint so you can examine the resulting byte array.
The difficult we do right away...
...the impossible takes slightly longer.

?test.ToString();
"2426186d-b96d-4656-9b65-15c727744643"
byte[] bytes=test.ToByteArray();
{byte[16]}
[0]: 109
[1]: 24
[2]: 38
[3]: 36
[4]: 109
[5]: 185
[6]: 86
[7]: 70
[8]: 155
[9]: 101
[10]: 21
[11]: 199
[12]: 39
[13]: 116
[14]: 70
[15]: 67... and the byte order is messed

So can you use test.ToString()?

Yes,
?test.ToString().Replace("-",string.Empty);
"2426186db96d46569b6515c727744643"
will fit my needs. So this will be the permanent workaround as solution. But the (IMHO) missbehavior with .ToByteArray() will remain. THX anyway, Nicki.

It' not misbehaving. It's doing exactly what it should be doing. ToByteArray is not setup to return an array of bytes to YOUR liking. It's setup to return an array of bytes that can be used to quickly build another Guid object.
Internally, the GUID value is not stored as an array of bytes, but as individual fields of various types, combining to form a single GUID. These types include Int32, Short and Byte.
What you think is misbehavior is the correct representation of a 32-bit integer and of a Short and of individual bytes.

Why don't you use "test.ToString()"?

Quick Test in Immediate Window:
Guid test=new Guid("{2426186D-B96D-4656-9B65-15C727744643}");
{2426186d-b96d-4656-9b65-15c727744643}
_a: 606476397
_b: -18067
_c: 18006
_d: 155
_e: 101
_f: 21
_g: 199
_h: 39
_i: 116
_j: 70
_k: 67
?test.ToString();
"2426186d-b96d-4656-9b65-15c727744643"

I want to create a table "Employee" with columns:empname,age and empcode(which takes two letters from employee name and append number to it.,e.g.:-ga1,om2 where ga stands for ganesh,om stands for omkar)
please help me with the following

It's already in the C# forum; please don't cross-post.
FWIW, sounds like a calculated field to me.

Where are you stuck?
There are only 10 types of people in the world, those who understand binary and those who don't.

Take the first two characters of one name and concatenate to the other.

Hello, my 2nd post here, so I'm a bit of a nOOb.
AFAIK the convention for using Radio Buttons is to have 1 selected by default.
Q: Is it reasonable or acceptable to break this convention for the purpose of forcing the user to make a deliberate selection in a customised application?
B/ground: I made the buttons myself using Small Basic and they are for a Pizza order form. One group has 2 sets of buttons, 1 set [small, medium, large], 2nd set [thin, thick]. The user can only continue once selection is made.
Currently I'm thinking why not by considering that a convention is a wise and preferred norm as opposed to a rule which may not allow such discretion. Also I read that some API's allow the use of RB's without having 1 selected by default.

Sure, I don't see why that wouldn't be acceptable. It is a practice used many places. As an example, on the CodeProject main page, there is a new survey every week and when it is the type that requires a radio button input, none of the options are initially selected.

Thanks Soren for your helpful reply.
Wow I just realised it is xmas on the other side of the planet. Happy xmas.
Yeah I think conventions are contextual. 'When in CodeProjectLand do as CodeProjectarians do'.

I wouldn't say that, I see that behavior all the time, referring to the CP survey just seemed like an obvious thing to do.

Thanks, helpful reply. And I agree.
In my solution to the exercise, not only was it obvious, I stated (on the other forum) that the hypothetical pizza shop owner wanted it. Happy user? That's gotta be good.
Appreciate your experience and thoughts.
