you cannot convert a string to a form, I would hope that is obvious. You could make the tag of the item the form that your string refers to, and then grab it from there, or build a map of strings to forms.

Array declaration and asigning value of array to combobox

Hello Experts!!

I am declaring one array (having size 10) as an integer and bind array data to grid combobox.It works well but in combobox it shows values as well as zeros....means if array contains 3 values then remaining values shows zero(remaining 7).
How to taggle with this? Combo shows like this->1,2,3,0,0,0,0,0,0,0...I dont want that zeros

My code is

<pre>Dim o As New design
Dim i As Integer = 0
Dim rowArray As String()
Dim no(10) As Integer //Declaration
rssearch = New ADODB.Recordset
rssearch.Open("select srno from design", con, ADODB.CursorTypeEnum.adOpenDynamic, ADODB.LockTypeEnum.adLockPessimistic)
While Not rssearch.EOF
o = New design
o.dsrno = rssearch.Fields("srno").Value

Dim row1() As String = {o.dsrno}
Dim rows() As Object = {row1}

For Each rowArray In rows
no(i) = rowArray(0) // Assign value one by one
i = i + 1
Next rowArray

o = Nothing
o = New design
rssearch.MoveNext()
'i = i + 1
End While

CType(dgvbottom.Columns(8), DataGridViewComboBoxColumn).DataSource = no // Display values in combo

This is why you should use dynamic lists instead of fixed arrays. The control is doing exactly what you asked it to. Use List<int> instead.

hi,

an int array of dimension 10 always contains 10 numeric values, they get initialized at zero.

solutions:
1. give your array the right dimension
2. use a collection instead of an array, say a List Of Int

You are working with a completly different control. The DataGridView does not have the concept of the Template column. Google working with DataGridView, there are plenty of examples out there.

You need to work with datagridview and add 2 additional columns, for example DataGridViewLinkColumn. For each one of those columns add events, for example:
AddHandler DataGridView1.CellContentClick, AddressOf Lnk_CellContentClick

Private Sub Lnk_CellContentClick(ByVal sender As Object, ByVal e As DataGridViewCellEventArgs)
Select Case e.ColumnIndex
End Select
End Sub

Infopath: help with implementing code

I have been provided these two code sources:

http://www.outlookcode.com/codedetail.aspx?id=88

and

http://www.outlookcode.com/codedetail.aspx?id=83

to generate a new meeting request in Outlook. My goal, is to use code (i've been told these will do what I need) to be able to send a new meeting request via an infopath form. The reason I want this done in Infopath is so that I can generate a print view form for users to have a custom brochure. I would like for users to fill out the form in infopath and upon clicking the submit button, have the meeting request send in outlook. I am not very familiar with coding, so if someone could walk me through the steps to implement this (or another) code to make this happen, I'd greatly appreciate it.

Thank you.

Programming is somewhat more complicated then browsing for code-snippets and mixing them. You might consider outsourcing your project if you have no practical experience.

My apologies, I know that this isn't the answer you had hoped for.

DateTime.Now should work since whenever you change Windows clock BIOS time changes as well.

Concerning XSDs....

LostMonkey6-Jul-09 0:50

All,

This may be a silly question, but what is the accepted "norm" when using XSD files in a project?

For me I see 2 ways to use them...either make a huge one that is a schema of your database and define all the relationships etc within it.

OR

Define lots of little ones that perform certain tasks, for example you may create an XSD that might contain just the schema, relations etc for a Customer/Order/Order Line/Product scenario.

I can see the big all in one file being a bit slow when creating objects from it but easier to maintain, but I can see the smaller one being more task focused but a bugger to maintain...or is that the trade-off?

So, generally, what is the "best" usage for a given scenario or what is the accepted "norm" when dealing with these files??

Thanks,

Monkey

If you use XSD's as a definition of your datamodel i would surely choose for one definition. Otherwise you will get the same problems as 2 apps each having a seperate database that must communicate with eachother (how do you maintain integrity then?)

Hi there, hope someone can assist me on this.

Ive got a datatable that gets Data from SQL.
Now what I want to do is add a unbound Image datacolumn to this datatable.

But the image must be a linkbutton.
When its gets click it should redirect to a page carrying over the other datagrid Colums as parameters.For instanse

-------------------------------------------
Col1 | Col2| Col3| Col4 | NewImageColumn
--------------------------------------------
Row1 Row1 Row1 Row1 Row1
Row2 Row2 ROw2 Row2 Row2
Row3 Row3 Row3 Row3 Row3

Lets assume the DataTable has 3 rows
When clicking on the NewImageColumn on lets say row 2
it should Redirect(pgSomepage.aspx? Row2.Col1 & Row2.Col2 & Row2.Col3 & Row2.Col4
