It takes a long (I forgot to grab the method signature). As for exactly what it does I'm not 100%, it was something I was trying to do with parsing outlooks MSG files.

The whole thing has been like wandering around in a big dark cave looking for a sandwich WTF | :WTF:

That code is from someone who was parsing MSG files with VBScript but it turned out that the MSG file I had didn't even have anything that could be converted using that function.

I just posted it up incase anyone is ever search on the lines of code.

I just ask because if it's something like milliseconds, you can do it in a single line of code:

Dim d As DateTime = New DateTime(1901, 1, 1).AddMilliseconds(val)

All you have to know is the date that the epoch starts.

Yeah, if it turned out this method was what I wanted I would have looked into it more and figured out exactly what the code does Smile | :)

As it turned out it was another deadend Smile | :)

All timestamps start with a known epoch somewhere. All you have to do with this code is plug in a known value for the date/time serial number and see where the date/time ends up, then adjust the starting point accordingly. In my example, that was Midnight, Jan 1, 1901.

Hi All,

I am working with webservices and its security.

I have a webservice and client application.now i need to secure the web service while calling and as well as serving the request.

I had created the x509 certificate and ........

Now i am not able to proceed further...

I will give the sample code i wrote in order to authenticate the user using the x509 certificate:

<WebMethod()> _

Public Function NewAuthentication(ByVal mvarUserID As String, ByVal mvarpassword As String, ByVal X509cert As X509Certificate) As DataSet 'UsernameForCertificateAssertion) As DataSet

Dim ds As New DataSet
Dim cert As New RLDInvData.Security()

Dim XCert As New System.Security.Cryptography.X509Certificates.X509Certificate()
' Dim file As New String

' XCert = System.Security.Cryptography.X509Certificates.X509Certificate.CreateFromCertFile("").ToString()

Dim pol As New MyPolicy()
XCert = X509Certificate.CreateFromCertFile(pol.ToString())

If Not XCert Is Nothing Then

Dim objSec As New RLDInvData.Security()
'Dim objSec As New RLDInvData.Websecurity

ds = objSec.Logon_DS(mvarUserID, mvarpassword)

X509cert = XCert

objSec = Nothing

End If

Return ds
End Function

RLDInvData is the dll file in which i wrote the class for security which is called after calling the webservice.

Pls help me in getting the X509 certificate and pas it as a parameter and process the authentication.

Thanks in advance

Drawing on Images?

I am working on a dental software.I need to display all 32 teeth of a selected patient with markings of each treatment he had undergone.I am displaying images of all 32 teeth on the form, without any treatment shown, in 32 picture boxes.If there is a treatment on a particular tooth it should be shown in the picture box with a differnt appearance indicating the treatment he has taken.For example if he has taken a root canal treatment for tooth no.4 then the root portion should be filled with red color.If another treatment is taken on the same tooth then that treatment also should be displayed in the figure along with the previous treatment.My problem is how to go about it.Any programming idea and/or code samples are welcome.

One possible way would be to investigate the Microsoft.Ink namespace. This would allow you to annotate the images (works with a mouse, not just the pen) and this Ink could be serialised into the database.

An advantage of this is that the original images are kept intact and the storage space is very low.

There are many ways of doing this but as someone familiar with ink applications I would be tempted to do it this way

It explains it all, but in C# - I dont know how easy it will be for you to convert but if you have difficulties post back and I will do some conversion for you

Throw away the picture boxes. your app is becoming complex enough that you should be drawing the teeth in your paint event. Then you can also draw on top of the teeth, where you need to color code things, etc.

If I get this right, you need to work out sections of a tooth based on discoloration ? Or can you just draw anywhere/the area is known ?

So in my clear i alllowed a User to Navigate through the record in my table, and Add, Edit and Delete. that one is Fine. when they Add , i had to clear my text boxes, that i did. but now here is the Problem.

"when i user Skips a textbox that, it populate a value, that user it not not Enter

e.g in txtExtension it will automatically put "2". sometimes we have properties with no Extension, so we want to leave it blank" .

when i unbind the textboxes, it does not populate. the text box when skipped.

what Should i check in my code

what is wrong with my dataset

There is an article here

which creates a dump of schema information for AD. There are also MMC plugins which can do this as well.

Try 'wWWHomePage' or 'url' If you are going to need more properties i would still recommend taking a look at the previous link which lists them all or getting a copy of ADSI Edit which is a useful app for exploring the AD.

Hi all,

Can i create an file like abc.inc and store like the code segnment below.?

<br />
enum Colours<br />
    {<br />
        Blue, Green, Red<br />
    };<br />

<br />
Blue<br />
Green<br />
Red<br />

Can you tell me how to include this abc.inc in the codebehind page.ie in default.aspx.cs file.

I know we can include files like this in classic ASP. I want to get the data from the file using a webservice and display in a list control, inside a windows form.

What will be best method to implement this?

what i am trying to do is to create an enumeration for colour indicators
like
enum Colours
{
Blue, Green, Red
};

In the UI i will show the colour values in the List Control.
when i add or edit the enumeration member, that change should reflect in the UI.
This is the scenario.....

waiting for your valuable suggestions

Thanks

Sebastian

How does that help ? He can read it and display it, but not use it in code.

if he want to deal with color(add new color or modify the values), storing
the value in xml file and read it agian when needed will be a good
option.

But here i a doing the same thing with .inc file.
Is there any performance difference...
Or is there any other alternative to do this without storing in any file

No.

Are you using ASP.NET ? The answer is still no. ASP was and is crap. This is way better. If you want something visible everywhere, put it in a class, and you can get to it anywhere. Or, put it in a base class for your page. This is the same advice I gave you when I answered this question yesterday.

Sebastian T Xavier wrote:

Blue, Green, Red

.NET has a Colors enum, but it's pretty big, it may not suit you. Either way, your enum is visible everywhere, by default, as all your code is in a project, and can be accessed via the classes that contain them.
