There is several ways to approach this.
First, get a reference to the Document object within the AxWebBrowser.
The best time to get this reference is on the DocumentCompleted event.
This will give you access to the underlying objects contained within.
You can optionally tie into the eventing of the browser object itself. But you'll need a reference a COM library Microsoft Internet Controls and another one for Microsoft HTML Object Library.
With references to these two libraries, you can declare the Document object WithEvents. Assign the Document to local (withevents) variable. Then place code in the event of that variable's event procedures.
This techique I've used, and you can ultimately do pre and post processing on any HTML objects that show in the page. In addition, you can gain full control over the Styles used within the HTML. For instance, you can set Styles dynamically on the HTML elements once you gain a reference to them.
Lastly, you can gain access to the Window object contained through the reference to the Document object. Then you can detect any of the areas the mouse is over or on.
Hope this helps!

Hi in sqlserver stored procedure i am doing some calculations...,
See the below procedure:
select a.empid,b.empName,c.Whrs,c.srg,case when srg=0 then @Outsunday else @Insunday end as days,c.Bassalary,
(Bassalary/(days*Whrs)) as onehour,
sum(AppWHours) as TWhrs,Sum(AppOtHours) as TOThrs
from tblMonthHourDetails a,tblemployeemaster b,tblsalarydetails c where
a.empid=b.empid and a.empid=c.empid and
b.projectid=@projectid and datepart(mm,[SDate])=@months and datepart(yy,[SDate])=@Years group by a.empid,b.empName,c.Whrs,c.srg,c.Bassalary
In that above procedure using case condition i am getting one column "days" like...,
That days value i want to use to calculate for onehour column,
if i give there days(highlighted in above procedure) value its telling error msg like invalid column days like...,
but i want to use that value there how to use...,
Plz any one solve my probs.....,
Magi

You can do a nested query, but this is probably better:
case when srg=0 then (Bassalary/(@Outsunday*Whrs)) else (Bassalary/(@Insunday *Whrs))end as onehour

Stored VB.Net procedures consisting of many subroutines and a few functions
working with one SQL Server 2005 datbase. The problem is as follows:
Sub A receives a table name, a query name, and a directory path name.Using
Dim RecordTypeSet As SqlDataReader
Dim RecordTypeConnection As New SqlConnection
Dim RecordTypeCommand As New SqlCommand I open a reader
from the sql located at directory path name & query name
and While RecordTypeSet.Read()
I create a record which I want to store in the table name provided.
In order to do this I call a SUB B with the record and the Table name.
Sub B builds an insert query and using
Dim SummaryConnection As SqlConnection
Dim SummaryCommand As SqlCommand
Dim SummaryReader As SqlDataReader
SummaryConnection = New SqlConnection("context connection = true")
SummaryConnection.Open()
SummaryCommand = New SqlCommand(sql, SummaryConnection)
SummaryReader = SummaryCommand.ExecuteReader()
errors out on SummaryConnection.Open()
end sub B
wend

What's the error?? Why does everyone leave out the error description when they post "I have a problem!"?
Does the method that this error occurs in have the SqlProcedure attribute on it?

With SqlProcedure Attribute I get a deployment error on SUB_A
because it has a Byref Class instantiation to return data to the caller

This is utterly useless. Copy and Paste the code in a post. The "Sub_A" crap leaves out details that are required to see what's going on.
You also didn't answer my question. Does the "sub" have an SqlProcedure attribute? Copying and pasting the code probably would have showed that! And, the EXACT error message would help more, not your interpretation of it.
The "context connection = true" only works inside an SqlProcedure attributed function. Without it, you may as well use a seperate connection using a normal connection string.

I did not originally have the sql server attribute declared

It "aborted" with what error message?!! Do you actually want help? This is the third time you've been asked for the error message. Why are you being so evasive?
I'd love to help, but I'm not going to read through the code looking for the cause of an error until I know what error I'm supposed to be looking for.

Running the code last provided
"Error The context connection is already in use. occurred in Module: sbUpdateSummaryProfitnLossTableRecord"
"Error 5 occurred in Module: sbUpdateSummaryProfitnLossTableRecord" was obtained from my error handling
I captured the following output.
A first chance exception of type 'System.InvalidOperationException' occurred in System.Data.dll
A first chance exception of type 'System.IO.FileNotFoundException' occurred in Clrtest
I think I am trying to use MARS in this environment. Is this even possible?

Hello,
[VS 2005]
I have created a user control that has a tab control, text boxes, combo boxes. I have a typed dataset with some datatables and tableAdapters for doing the inserts and the delete, and updates.
I build the control and when I want to use this control in another project.
1) open a new windows form project
2) Create a new tab on the tool box
3) Choose items
4) Browse to the dll in the release folder.
My question when I add the dll it also adds the typed dataset, table adapters. I have done something wrong as I think it should be the control itself and not the table adapters and the dataset. As when I click ok with the above selected it add them to my toolbox.
Can anyone explain about this, and if I have done done something wrong.
Many thanks for your help,
Steve

How to get or to collect all objects or controls in a form using vb.net? For example of controls are Textbox, Combobox and check box.
|
|
|
|
|
Every form has a Controls collection. This is where you'll find all the controls on the form. There's a little bit of a "gotcha" though. Controls can have Control collections of their own, so you can end up having controls inside other controls, like RadioButtons in a GroupBox or Panel.
You can enumerate the controls like this:
For Each c As Control In Me.Controls
If TypeOf c Is Panel Then
Dim tb As Panel = DirectCast(c, Panel)
' do whatever you want with the Panel you found
End If
Next

The code is nice and all, but where's he going to get the ChilkatZip2 class library from?

You can use the #ZipLib to do this. Find it here[^].

You'll have to create a custom label control for this, easily done by inheriting from the existing Label class. You'll need to add a Timer to your control, and a couple of properties and methods so you can set the blink rate and start and stop the blinking. Then it's just a matter of making the foreground color match the background color and changing it back to what it's supposed to be on every timer tick.

Use a timer to set the Visible property of the label to either true or false.
