I think you just need to order your data source on level, and just create the nodes within a loop - no need for a case statement. Level 0 will not have a parent, otherwise, PID should be the parent node.

You can try Solution Explorer for access the form.
Secondly may be your form.resx file contants are missing or deleted.
If you are saying about Forms Group Box then you can select the Object from Property window and set it's property for visible and location and Size also.
if any other query pls contact.

Is there an easy way to get the infomtion from a DataGrid and dump it into MS Excel using VB6?
|
|
|
|
|
|
I am using VB6 - the datagrid I want to export to Excel is about 5000 records 20 colums wide.
Is there a way to dump the entire datagrid at once or does one need to read each record/cell and transfer it to Excel?
|
|
|
|
|
You can export the data from Datagrid to MSEXCEL.
How can it possible pls contact ?

Store the node object that is being replied to, and add the new reply as a child to that node.

Why are you displaying only the "billno" field in the report? Would you not need to display other details too?
Fields placed in the PageHeader will appear once every page - so if your database contains 4 bills, the report will contain 4 pages, with each page header containing one of the billno fields.
You cannot directly display multiple billno fields horizontally. In any case, what if there are thousands of records in the table? You will need to look into creating a temporary table with as many fields as you want to display horizontally in your report.

hi,
first choose section Expert which show all the section of your Report on left hand side and related option on right hand side.
Now choose Details section and check the Checkbox with name "Format with multiple column". when you check this option, one extra tab(name "Layout") is added in panel located at Top-right corner.
click on layout tab and set Detailsize ,Gap between Details and printing direction related field
after appropriate setting ,click on ok button.This action Change the width of details section.Now place the bill number related field in detail section and run the report
hope this helps

You can use dataset to print the data from Exe to Print.
it's no needful for connection by database.

Hello, I was wondering if u can help me out with this one....
I have a datagridview with 5 columns, the first one is a Combobox Column... I've managed to fill it up with a datasource...know what I'll like to know is how to fill the remaining 4 cells of the row, based in the code i've selected in the first one...
I've been searching a lot and i've found some examples of how to capture the event of the combobox...
<br />
Private Sub dataGridView1_EditingControlShowing(ByVal sender As Object, ByVal e As DataGridViewEditingControlShowingEventArgs)<br />
Dim editingComboBox As ComboBox = CType(e.Control, ComboBox)<br />
If Not editingComboBox Is Nothing Then<br />
AddHandler editingComboBox.SelectedIndexChanged, AddressOf editingComboBox_SelectedIndexChanged<br />
End If<br />
End Sub<br />
<br />
Private Sub editingComboBox_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)<br />
Dim comboBox1 As ComboBox = CType(sender, ComboBox)<br />
' Display index<br />
MessageBox.Show(comboBox1.SelectedIndex.ToString())<br />
' Display value<br />
MessageBox.Show(comboBox1.Text)<br />
End Sub
Here's a picture of the form...
http://img90.imageshack.us/my.php?image=screenin9.png
This isn't helping that much because what i'll like to do is this:
Get the Code of the zone "Zona" in the picture...(i dont know how to  ) and based on that go to the DB and based on a store procedure get the remaining information
Well thanks a lot... if u can tell how to capture the event of change a value in the combobox will be more than enough 
Greetings from Lima - Peru

You might want to take a look at the grids CurrentCellDirtyStateChanged and CellValueChanged events. The CurrentCellDirtyStateChanged event triggers as soon as any change is made in a cell, although the actual new value of the cell is not "known" in that event. The CellValueChanged event triggers as soon as the user exits a modified cell, and the changed value of the cell is known in that event. I've done some crazy stuff in the past where I've programitically moved off a cell when the CurrentCellDirtyStateChanged event triggers, captured its new value via the CellValueChanged event, and then programtically returned to the cell. You can get the new value of the cell in the CellValueChanged event with code similar to the following:
NewValue = dataGridView1.CurrentRow.Cells(e.ColumnIndex).Value.ToString()
