what if you want different table styles pointing to the same table. The app that I am working on is one that is used to correct tests. There is more than one type of error. Right now I have all the data being retrieved and thrown into the same table. I may have to change this is base the query on the correction mode and insert the data into different datatables, I really should do this, but I am still curious of the present problem.
I would like to create tablestyles, which I though that I did, so that in the different correction modes different columns are displayed, but I get an error when I try to do this:
<br />
An unhandled exception of type 'System.ArgumentException' occurred in system.windows.forms.dll<br />
<br />
Additional information: The data grid table styles collection already contains a table style with the same mapping name.<br />
Now they are the same mapping name, because the mapping name is the name of the table right?
Thanks for the help

hey kowplunk, sorry about the delay in my response, i was out of town for a few days. 
anyways, the cleaner way to handle it would be to have the different data loaded into different tables and have the appropriate tablestyle handle the appropriate table. however, i can't say for sure that this is the case as i have no idea what the table structure looks like, what the resulting data looks like etc.
i guess if you have the same data but you want to display it in different ways you could just load everything into the same table, then when you need to change the way the data is displayed, release the mapping name of the current tablestyle (via code) and then set the mapping name of the secondary one. as you found out you can't have two tablestyles pointing to the same table at the same time.
however, if you're intention is to show different columns etc. at different points, i think you might be better off with the multiple table solution.

Thanks for the help. Actually the error message was pretty descriptive. In the different styles that I had there was column mapping names that were the same and it doesn't like that, but it is easy to change. Everything is working awesome now. Thanks again.

You didn't post the most important part of your code. What does the SQL statement look like? This is where your going to put your WHERE clause with your date information.
SELECT fields FROM tableName WHERE datefield BETWEEN @date1 AND @date2
Your @date1 and @date2 should be parameters in your SQL command and have corresponding SqlParameter objects created and filled. In your case, something like this:
dbcomm.Parameters.Add("@date1", SqlDbType.DateTime).Value = firstdate
dbcomm.Parameters.Add("@date2", SqlDbType.DateTime).Value = seconddate

Hi..
I assume that your datagrid has a datasource / datamember one table from a dataset.
if you add a new row to your table then the grid will show the new row as empty textboxes
example
'we asume that you have already a dataset ( named dataset1 ) and in the dataset is a table ( named table1 ).
private sub addrow
Dim newrow As DataRow
newrow = DataSet1.Tables("table1").NewRow
DataSet1.Tables("table1").Rows.Add(newrow)
end sub
this sub adds a row to your table and this row must be shown in the binded datagrid as empty textboxes.
Hope i helped you.
Ramaseb.

hii every one,
i need to convert from the doc file to html..not by using save as in the ms word.. coz it makes problems with the arabic laguage...it will be helpful if i know the structure of the doc file...
any one can help ??

You'll have a difficult time with this one. Your talking about writing an app that can load a .DOC file, the file structure of which is not simple nor easy to interpret, rendering it in a form that you can then go over and convert to HTML and images. This will be FAR from easy and I don't think there is alot of experience out there to help you. You might want to check out the Open Source sites, like SourceForge, and search for a Word document viewer to get you started. I don't know of any projects myself, but that doen't mean they don't exist.

On another question, is there any good Visual Basic example of how to draw a chart without having the program crash during the second time? Thanks in advance.

I want to return a value from textbox to other form when it opens, how to code the return?
my code:
In FORM1:
file_location = textbox1.text
Private Sub btnView_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnView.Click
Dim view As New frmView
MessageBox.Show(file_location)
If view.ShowDialog() = DialogResult.OK Then
End If
End Sub
Public Property ReturnView() As String
Get
Return file_location
End Get
Set(ByVal Value As String)
file_location = Value
End Set
End Property
In FORM2:
Dim AddJob As New frmAddJob
view = AddJob.ReturnView
TextBox1.Text = view
The problem is the view is nothing..it can't pass the value to form2..
does everybody know what's wrong with code? Thanks for your help..

If I'm reading this correctly you want to click on a button on form1 which contains a textbox and pass the contents of the textbox to Form2.
Simply set up a module with a variable mvarfile_Location as string. When you click on the button. Set this public/friend module level variable and show form2. In the form2 load event - retrieve the contents of this module level variable mvarfile_Location .
FORM1
*****
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim Frm2 As New Form2
mvarFileLocation = TextBox1.Text
MessageBox.Show(mvarFileLocation )
If view.ShowDialog() = DialogResult.OK Then
End If
End Sub
FORM2
*****
Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
me.text = mvarFileLocation
End Sub
End Class
Module test
Public mvarFileLocation As String
End Module
Of course you could use a class and properties etc. But basically you are putting the contents into a variable/property etc. accessible from both forms.
Alternatively
You could pass a reference to form2 from form1 and use this to directly access form1.

I am trying to iterate through a hashtable using an enumerator. I want to change some values as I go.
Here is a simplified version of my code….
ptr = hashTab.GetEnumerator<br />
<br />
While ptr.MoveNext<br />
hashTab.Item(ptr.Key) = "something different"<br />
End While
I get the following exception when I change a value – Collection was modified; enumeration operation may not execute.
What is the correct way to perform this type of operation?
John.

The problem occurs because you are completely replacing the item in the hashtable. This is not allowed during an enumeration.
If your hashtable contains objects, it is allowed to update properties of those objects. So one solution is to create an object (or type) that contains the string value.
Another solution is to build a new collection, and then discard the old one.

Hashtable belongs to readonly dictionary base object. Thu editing the content is not possible.what you can do ir remove the key and add it again with the new value:
hashTab.Remove ptr.Key
then...
hashTab.Add ptr.Key, “something different”

I'm trying to save a MS Word shape of the type msoDiagram into a separate file and to this end I thought if I could convert the diagram into an image , then I could easily save the image into a file. However I'm unable to figure out a way to convert the diagram into an image - anybody has any idea ?

if you are using MS Office 2003 you can print your document to MS Office Image writer, this will create a YourDocument.mdi file for you after you open it (by double clicking it) you can use the Save as... to save your file as image (YourDocument.tif)
Hope this will help
