You didn't actually read the link I posted, did you? Perhaps followed the links on that page to the place where you can probably download the SDK version and grab the security tools from it, maybe...

Hi all,
I have created a COM wrapper component in c#.net. I generated .tlb file out of it. Also I added reference to tlb file in VB 6.0 application and can able to call functions of COM wrapper.
In C#, i have declared a stringcollection to collect all the errors.But while mapping,this String collection is converted to Unknown in VB 6.0 and becoz of that i got mismatch error.
so i changed the stringcollection to Arraylist in C#.
This Arraylist is converted to String in VB 6.0 while mapping.
and i got error while i tried to retrive the string.
Plz give me suggestions on how to call a Stringcollection/arraylist in VB 6.0.
Thanks in Advance,
cheers

You cannot pass any System.Collection objects back to VB6. You'll have to convert this collection to an array of strings to send it back to VB6.

What are the differences?

I need to crete child Nodes
|
|

I am guessing that you have more than one episode per patient and more than one visit per episode. You can always write your own filter to create the XmlDocument you need by iterating through the rows and adding the appropriate nodes to the XmlDocument. Then you can call the Write() method of the XmlDocument.

Yes you are right... but i dont know how to write node by node using Dataset.. pelase can u help me
|
|
|
|
|
Try something like this:
Dim doc As XmlDocument = New XmlDocument()
Dim tableName As String = "myTable"
Dim node, attrib As XmlNode
Dim parentNode As XmlNode = doc.DocumentElement
For Each row As DataRow In ds.Tables(tableName).rows
node = doc.CreateNode(XmlNodeType.Element, "myElement", myNameSpaceURI)
attrib = doc.CreateAttribute("myAttribute")
attrib.Value = row("myAttributeColumn").ToString()
node.Attributes.Append(attrib)
parentNode.AppendChild(node)
Next
You just need to adjust this to fit your own table.

Why don't you use Gridview with checkedboxes?
lembayung wrote: do i have to create another table?
Yeah.. there will be three tables like Students, StudentCourse, Courses.

im new in vb so i dont much....regarding to ur reply, are you referring to vb.net?do we have gridview in visual basic?
|
|
|
|
|
Wow.
If you're that new to VB, you should be buying a book on winforms and reading it. Yes, VB.NET has a gridview control.

This is what ive done....there's no error when i compile the codes but...all the data is not saved to studentcourse table...why is it so?
For i = 1 To ListView3.ListItems.Count<br />
If ListView3.ListItems(i).Tag = "" And ListView3.ListItems(i).Checked = True Then<br />
<br />
sql = "insert into studentcourse( peid, pengkod, bioid) " & _<br />
"values ( " & _<br />
"'" & ListView3.SelectedItem.SubItems(1) & "', " & _<br />
"'" & holdPENG & "', " & _<br />
"'" & holdBIO & "')"<br />
<br />
db.Execute sql<br />
<br />
ElseIf ListView3.ListItems(i).Tag <> "" And ListView3.ListItems(i).Checked = True Then<br />
<br />
sql = "update studentcourse set " & _<br />
"peid = '" & ListView3.SelectedItem.SubItems(1) & "', " & _<br />

I'm running into a bit of a snag here;
I'm loading an excel spreadsheet using the following code
Dim Ole_connection As System.Data.OleDb.OleDbConnection
Dim Ole_command As System.Data.OleDb.OleDbDataAdapter
Dim Ole_dataset As New System.Data.DataSet()
Ole_connection = New System.Data.OleDb.OleDbConnection("provider=Microsoft.Jet.OLEDB.4.0;" & _
"data source=" & Str_filename & ";Extended Properties=Excel 8.0;")
Ole_command = New System.Data.OleDb.OleDbDataAdapter("select * from [Sheet1$]", Ole_connection)
Ole_dataset.Clear()
Ole_connection.Open()
Ole_command.Fill(Ole_dataset)
Ole_connection.Close()
I have no control over the data that I receive (the excel spreadsheet)
it's generated by a pbx system at midnight.
The problem is the spreadsheet is not as flat as I was lead to believe, the first sample data I was given was 9 column of data;
in the real version most of the spreadsheet is like that except for the first 7 rows of the spreadsheet which is branding and titles and one or two pieces of info that I do need (dates and a group name)
Is there any way for me to figuratively force the square peg into the round hole? forcing the dataset to be 9 columns large(this is never going to change) and just shoving the 7 first rows of un-flat data wherever it may fall?
|

|

Would using p/invoke to open the Excel sheet as a COM object work as an alternate option for you?
|
|
|
|
|
I'm not certain, never used that before, so I am googleing it as type this;
Maybe a bit of background on what I'm doing will help
Every day our phone system gives us an excel spreadsheet of over 2000 rows, other then the aforementioned un-flat data in the 7 lines, the sheet contains;
this wont show up properly here but
-A small header
Workgroup: WG-NBA-Montreal (continued)
Username: username (Active)
Agent Name: Testing, The fish
-Titles for every column:
" Logged-in Time Frame or Reason Unavailable""Logged-in Time or Time Unavailable" | Begin Time | End Time | Originated
Logged-in Time Frame 11/5/2007 12:04:17 11/5/2007 20:25:54 08:21:37 23
Pre-Shift Unavailable 11/5/2007 12:04:17 11/5/2007 12:08:30 00:04:13
Initializing Unavailable 11/5/2007 12:04:17 11/5/2007 12:04:17 00:00:00
Break Unavailable 11/5/2007 14:44:15 11/5/2007 14:44:15 00:00:00
-several more rows for one agent
- then the header portion for the next agent and row of data for him, and so on and so forth.
This is from the sample I was given so the data is fake. but the format is right
anyway what my application does is load the sheet into a table and then I parse for each agent the various states they are in during the day and build a report that says when they are late, when they take breaks that are too short or too long based on bounds that are configured.
right now this is done manually so I'm just automating the process to shave a few hours of aggravation for the person who has to read those 2000 lines
everything was working fine with the sample data, but once those 7 lines of header came in everything got scrapped and most of what was there before is now null.

Since you will be opening the Excel file not as a recordset, but as a spreadsheet, you will be able to write your parser anyway you want, so I imagine your requirement should not be so difficult to implement.
Hope you got the information you needed on p/invoke?
|
|
|
|

It may just be my Google skills that are sub par but all I'm finding is books for sale and how to insert a spreadsheet as an object in a form.
|
|
|
|

I guess I should have also mentioned that you can find this as Microsoft Office Interop too... sorry 
Does this help? http://www.codeproject.com/KB/office/office_automation.aspx[^]
I know it talks about exporting to Excel (and is in C#), but the code to open an Excel file is present and a few of the Excel cell and range operations are also demonstrated...
There are also a few other Interop articles on CP, though I haven't actually read through those.
Hope this helps

how do you delete empty elements ("") from an 1 D array? I have mixture of numbers (0-24) and "" characters. I want to strip out all the elements with the " char.
Thanks
EM

You can't delete any elements from an array. You can't change the size of an array once it's created.
You can create a list and add the items to it, like:
Dim result As New List(Of String)()
For Each s As String in someArray
If s.Length > 0 Then result.Add(s)
Next
Experience is the sum of all the mistakes you have done.

I have a form with an imagecontrol (2 icons) and 2 listviews. I have loaded file names and icons into the first listview control. I have set the tag property of the item in the first listview to the directory path of the file.
I need to allow the user to pick the files he/she wants from the first listview and add them to the second listview via a button. When I use the code below the icon does not appear. Furthermore I have to use the .Text property of the NewItem variable in order to add it to the second listview. My goal here is to be able to add the item to the second listview and I also need to add the tag property of the item in focus from the first lisview to the tag property of the item in the second listview.
Once the files have all been added to the second listview I load them into an array via another button. I am noticing that as I loop through the items in the secondlistview that although the variable X shows the files, both the name and tag properties are "".
Is this because I used the .TEXT property as stated above? How do I work around this?
Private Sub Button10_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button10.Click
Dim NewItem As ListViewItem
NewItem = listView1.FocusedItem
NewItem.ImageIndex = 2
listView2.Items.Add(NewItem.Text)
NewItem.Tag = listView1.FocusedItem.Tag 'Transfer Tag of item in listview1 to item in listview2
listView2.AutoResizeColumns(ColumnHeaderAutoResizeStyle.HeaderSize)
End Sub
"***************************************************************************************
Private Sub Button5_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button5.Click
'Load selected files into array
Dim Y As Integer
Dim X As ListViewItem
Dim Counter As Double
Y = listView2.Items.Count
ReDim FileArray(Y-1, 1)
Counter = 0
For Each X In listView2.Items
FileArray(Counter, 0) = X.Name
FileArray(Counter, 1) = X.Tag
Counter = Counter + 1
Next
End Sub

To move items from one ListView to another, you don't have to create a new ListViewItem. Just remove it from one ListView and add it to the other:
For Each item As ListViewItem In SourceFilesListView.SelectedItems()
SourceFilesListView.Items.Remove(item)
SelectedFilesListView.Items.Add(item)
Next
