As Dave and Nish have said, CAPTCHAs are explicitly designed to defeat OCR. It may not be totally impossible, you're going to have to do a good amount of research to try and process them. Noone has written a CCaptchaOcrConverter class that you can just copy/paste into your application.

PS IF you don't even know all the right questions to ask, you're probably not the right person to be doing the actual research either.

Hi,

"Reference to a non-shared member requires object reference."
can anyone help on this..
Thanks in advance

The message is clear

you need an instance of the object in order to access a non-shared member. Maybe some code post will help us (and you).

code used:
Imports WSDemo.demoref
Public Class Form2
Dim mservice As New MTVAS
Dim basicDesc As New BCDT()
Dim mn As New TVAMT
Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
mn.originID = "test"
mservice.importTVAO(mn)
End Sub
End Class
Error:
Reference to a non-shared member requires an object reference.
If i double click on the error it takes me to the Reference.vb file underlined code as below
<system.xml.serialization.xmlattributeattribute(datatype:="integer"), _
="" system.componentmodel.defaultvalueattribute("10")=""> _
Public Property preferenceValue() As String
Get
Return Me.preferenceValueField
End Get
Set
Me.preferenceValueField = value
End Set
End Property
End Class
The first statement of the above code is highlighted.
Hope this helps

Is this an instance field, or a shared field. You use it as an instance field. However, the compiler error indicates it is actaully a shared field.
So, it should either be an instance field (remove the Shared keyword from its definition)
OR
the property needs to be marked as Shared and the Me. in the getter and setter need to be removed.

Hi,
I have an button in my vb.net form, to show my help file (sample.chm). But I need to show only one instance of that help file, even if the user hits the button second time it should open the existing help file which already opened not the new instance.
Thanks in advance.
Be simple and Be sample.

Will it be easy to disable the button when a new instance of the help window is opened and enable it when done with the help window.

Yes, but how do i know whether the help window is opened or not - to enable/disable the button.

Hi there
This is my first post on this excelent site. I have an application which today is a pretty standart application. Theres a form, and theres an object doing all the work.
Well, now i have to split it up. I have to make the work-process as a "server-side" service, or something similar.
And the interface a "client-side" interface, which can do some basic controlling of the "server-side application" and also receive status from the server.
The server can run on multiple machines, on multiple LANs, even on multiple Domains.
When i open the UI i have to be able to monitor each and every server, and the works thats being done there.
Now that interface... The interface can actually also be instantiated on multiple machines.
The server application is a production tool, used on plants throughout the world. Each plant can have X amount of machines running the production tool. Then let's say there as production planner who wants to monitor the production, localy at the plant. He logs on and receives messages from all the machines. He can also click on a process and end it (due to errors or what not).
Another chief of production planning at HQ also wants to see whats going on in Italy, but he resides in germany. So he also just opens his Interface.
I've thought about using Remoting or MSMQ. But if anyone has any other options for me to use, please tell me about it, and maybe refer me to some articles.
The application is developed in VB.Net.

I think you should use web services for this. The client application can be windows application or even a web application. If it is a web application then there is no need to install it on every client machine and it will be easier to maintain.

Guys, I want to put my reports on a web service, or single network location, from where I will be able to download a copy of the report, then load it, at runtime to use in a desktop application.
I tried to use the DownloadFile method of WebClients to directly download the *.rpt file, but IIS is not returning the file  – any suggestions?
Trying to use web browser or free download manager to see if I can download the file brings up an unknown server error. Permissions were changed to allow read & write, anonymous access granted, no change.
I also tried to use the publish as web service feature on the report, when i load the *Service.asmx file in a browser, I will see the shared methods of the report in the browser  , but attempting to load the reportdocument with that url fails, attempting to download that file downloads the HTML source for the page viewed in the browser, which cant be used to load into reportdocument .
Am I trying to do the impossible here?
There's no dumb question

I have a project that uses a web service to download report files. So it is possible. One issue we had was that we had to setup the MIME type of .rpt in IIS of the machines that hosted the web service. It won't let users download a file that it doesn't recognize the extention of. You could test this theory by trying to download a .txt file (or other very common file extention type) instead and seeing if it works.
Hope this helps.

Not sure, but try this: Should return the absolute value of the time difference, regardless of negativity.
math.abs(tspan.hours)
Abs is short for absolute value (and it is an available math function), expressed in mathematics as |value|.
Eg.
|8| = 8
|-8| = 8

hey i didnt ask how to show absolute value
see my ques is i have intime(19:45) and outtime(8:53)
so if i use time span then i am getting value (10:59)
but exact answer is (13:08)
now u got it my ques...........,
i need difference between two times.............

well subtract the intime(19:45) from (24:00) then add it to the outtime. This is the basic premise, i'll leave the task of applying it to your code, up to you.
