I could be wrong, but I think the WebBrowser control needs to be on a form with a message pump in order to work. Since a Windows Service doesn't have a message pump, this could be what's causing your problem.
THe work around would be to not use a WebControl, but instead rewrite the code to use the HttpWebRequest methods instead.

Use the WebRequest class in System.Net. It's all pretty much self explanatory.

I have a for next loop which forms an integral part of my app ,it uses the no of lines in a richtextbox , but whenever i run it on the debugger i get that 1 is greater than RichTextBox.Lines.Length,so is there any other way to get the proper no of lines in the richtextbox????
|
|
|
|
|
RichTextBox1.Lines.Length
|
|
|
|
|
The only way to do it is RTB.Lines.Length. What "proper" refers to depends on the definition of the word and put forth by the person demanding it.
What do you mean when you use "proper" in this context? A line in a RTB can be many screen-lines long. To the RTB, it's a string of text that ends with a CarriageReturn character.
|
|
|
|
|
I found a solution , i changed the code from For index = 0 to RTB.Length to For Each String in RTB.Lines() and it started working,what i meant by proper was,irrespective of the no of lines in the rtb ,rtb.length always returned 0 ,now that i've resolved it i don't think it really matters

Hi All!
I'm a newbie programmer developing a Text Editor with built-in Text-To-Speech Capabilities.
I am writing this application using the VB .NET Framework.
I am having trouble using the Redo() Method in my code. When I use the Redo() keyword in my RedoToolStripMenuItem_click procedure I get an error saying that "Redo is not a Member of System.Windows.Forms.TextBox". My line of code that generates the error is as follows:
txtEditor.ReDo()
TxtEditor is the textbox in which I am trying to implement the method. How can I use the Redo method to be able to complete the RedoToolStripMenuItem_click Procedure?
Thanks
Josh

You must to use a RichTextBox to call the Redo method.
Trinity: Neo... nobody has ever done this before.
Neo: That's why it's going to work.

Thanks MatrixCoder! I've replaced the Text Box with a Rich Text Box and the Redo method works perfectly! 
I sincerely appreciate your quick and accurate reply to my question.
Thanks again!
Best Regards.

how new is new ? What other projects have you done ?

OK - very new. You can't invent keywords. there is no redo keyword. You need to write your own.
So, you need to keep track of the things you undo, so you can reapply them when you call redo.

i think you can't add more columns to a binded datagridview, but why don't you set the width of last column to fill the empty space

Hey Experts thanks in advance.
I am trying a client server application in vb6 using Winsock. The application works well on system where vb6 is installed but the problem i can't run the applications on clients in which vb6 hasn't been installed.
When i load the application it gives some sort of error message like winsock can't be detected or loaded.
I tried to recover by registering winsock from the command promt using
regsvr32/{path}/winsock.dll but again it can't be registered and error message is displayed "i.e winsock was registered but the entry point can't be detected !
And the application doesn't work
So plz anyone help me. Once again thanks in advance....

Hi I am new to .NET and just started coding in vb.net. I have a form (main form)that has a bound datagridview and when I click on one of the rows, I find the record and display it on a new form(update form). The textboxes in this new form are also bound to the same dataset. When I make changes to this record on this form, I am able to change the actual data in the database, but my row in the datagridview in the previous form does not change. I have to show the previous form to show the changes I made. How do I reflect my changes from my update form to just one row in the datagridview?
Please help! I tried everything, but nothing helps..
Thanks

Does anyone know how to select a specific row in a datagrid without having to click on the grey box to the left of each row?
IE if I have a datagrid "My_DataGrid" that looks like below:
Line# Name
1 Bob
2 Joe
3 Mike
If I use the code below and click anyware on the data Grid (Ie on the Joe field) I get UserName = Bob
private Sub My_dataGrid.Click()
dim UserName as string
My_DataGrid.refresh
UserName = My_DataGrid.Colums("Name")
end sub
If I click on the Grey Box to the left of Joe I get UserName = Joe
Any Ideas

try this
<br />
private Sub My_dataGrid.Click()<br />
dim UserName as string<br />
<br />
'My_DataGrid.refresh<br />
<br />
UserName = My_DataGrid.currentrow.cells(0)value end sub<br />
i hope your name column is first column in the datagrid row otherwise change the index as per your wish

Hi,
I have an application where on a lot of my ASP.NET pages i need to add text boxes which collect First Name, last Name, Age, Company Name etc and has a button which when clicked enters the above mentioned data into the database.It needs to be entered to the same database table all the time.No, I cannot use session info. I wanna know if it is possible to create a custom web control which does this? So I can add it to my tool box and drag and drop onto my pages as and when I need it. I havent seen instances where you can create a control which does db operation. I know you can use User controls(.ascx) but that way, it needs to be included in every project and every one can see the code and know whatz happening behind it. Help is appreciated. Samples are appreciated even more!!!
Regards
RH

I am trying to run an insert for each row on a datagridview that is selected (checkbox on 0 column index). My problem is that the @articleID parameter is not selected from the correct row. I want the to pick up the articleID from the row that is being iterated through. Looks like the currentrow syntax isn't working. Any suggestions?
<br />
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click<br />
Dim myCmd As New SqlCommand("sp_Create_NewPriceListLine", MDIParent1.Conn)<br />
myCmd.CommandType = CommandType.StoredProcedure<br />
<br />
For Each Row As DataGridViewRow In Article_searchDataGridView.Rows<br />
Dim include As DataGridViewCheckBoxCell = TryCast(Row.Cells("Select_Article"), DataGridViewCheckBoxCell)<br />
<br />
If Row.Cells("Select_Article").Value = True Then<br />
MDIParent1.Conn.Open()<br />
Dim discountID As SqlParameter = myCmd.Parameters.AddWithValue("@discountID", Me.DiscountIdTextBox1.Text)<br />
discountID.Direction = ParameterDirection.Input<br />
<br />
Dim articleID As SqlParameter = myCmd.Parameters.AddWithValue("@articleID", Me.Article_searchDataGridView.Item(7, Me.Article_searchDataGridView.CurrentRow.Index).Value) 'Me.Article_searchDataGridView.CurrentRow.Index).Value)<br />
articleID.Direction = ParameterDirection.Input<br />
<br />
Dim userID As SqlParameter = myCmd.Parameters.AddWithValue("@userID", MDIParent1.userid)<br />
userID.Direction = ParameterDirection.Input<br />
<br />
Dim myReader As SqlDataReader = myCmd.ExecuteReader()<br />
<br />
myReader.Close()<br />
MDIParent1.Conn.Close()<br />
End If<br />
myCmd.Parameters.Clear()<br />
<br />
Next<br />
End Sub<br />

Never mind....found the answer 
Dim articleID As SqlParameter = myCmd.Parameters.AddWithValue("@articleID", Row.Cells("DataGridViewTextBoxColumn1").Value) 'Me.Article_searchDataGridView.CurrentRow.Index).Value)<br />
articleID.Direction = ParameterDirection.Input

I'm not sure what you're asking. Have you tried the SelectedIndexChanged event or the ComboBox.Select method?
Trinity: Neo... nobody has ever done this before.
Neo: That's why it's going to work.
