Error When Adding Dataset To Mdi Child
Dec 11, 2009
I am using VB.NET 2008 Express. I had a project with a mdi parent and several child forms. On the child forms, I created a datagridview by dragging the necessary table from the dataset(s) from the data sources window.
Main form - PastorBase
Child form - IllustrationList
When I try to debug it, I run into several errors from the code of the IllustrationList.Designer.vb file in this section [Code] However, the moment I make any change to the control by modifying properties or simply resizing it on the form, my change in this code is lost. So I am repeatedly having to change these lines (there are about five per child form). I am uncertain of what I am doing wrong. Should the dataset, etc. be added to the parent form and then called from the child form? Is there some setting I need to change somewhere?

I have a MDI app in development that uses parent-child datasets. My problem is when I update a dataset on one child form I then need to update the dataset on another child form. I know the dataset update has been commited to the source as when I reload the second child form the changed values are displayed.
[Code]...
Main.CarTableAdapter.Fill(Me.RCCarV2DataSet.Car)Unfortunately when I close the form that executes the above code the "Main" form which is still open should display the new values in the bound controls but it doesn't. The only way I can get the changes to display is to close and reload the "Main" form.

I'm working on a program that allows me to edit XML data in a DataGridView. I have most everything working but I don't like my current TreeView Structure. I load the XML data into a DataSet and edit it there, so that is what I'd prefer to base my TreeView on. I've tried a few things such as..

basically what I want to do is compile a program from my program(parent) to a seperate program(child) which is a module I have created.
When I compile my child program from my parent program I want to add a .exe resource to the child and when the child program runs I want to run the resource I added.

So I'm adding a tab panel to a child window. A lot of our controls here are user defined but this looks like an ExtJS issue. When I add a tab panel, and then try and add controls and stuff to that panel, everything is cut off on that panel.
Here is the code I am using:
Using ViewDetailsWin As New Pages.ChildWindow
With ViewDetailsWin
.IconCls = Model.WorkflowStepDefinition.SmallIcon
.Ref = "viewDetailsWin"
[code].....
I can't even see the dropdown at all unless I scroll on the tiny little scroll bar it creates. It gives like a quarter inch on the screen to see anything inside the tab panel. There is no size property on the tab panel from what I can see.

Updating a VB6 prog in VS2005 on Windows 7. The prog has an MDI + child forms and there are a number of content types, with varying numbers of controls being set up and positioned from setup files.On forms which are not child forms I can easily add controls at run time like this:
Dim lab As New Label
With lab
.Left = 0 : .Top = 0
.Width = 800 : .Height = 800
[code]....
This doesn't work on a child form, no label is visible. Can't see any obvious problem in quickwatch.

[Code] I have a panel as the base of my custom control and I am adding other panels to it, along with a flow layout panel(myInnerContainer). I know the code above isn't going to work because when I try to add the regular panels to the main control, they will attempt to be added to the flow layout panel myInnerContainer, and cause a circular error. [Code] but intellisense doesn't display anything which leads me in the correct direction for adding only the buttons to the flow layout panel (myInnerContainer).

I was asked to create a program that inserts records into one parent table and multiple child tables. My question is, how do I know what the PK is for the parent table, so that I may add it as a FK in the child? The PK for the parent is an auto number. As I stated in my title, I'm using VB.net, mySQL, through an ODBC connection. I have to do this through the code and cannot use stored procedures.
my transaction looks like this:
Dim cmdText As String = "INSERT INTO candidate(first_name, last_name, phone1, phone2, email1, city, " _
& " state, country, zip,primary_contact_id ) VALUES (?,?, ?, ?,?,?, ?,?,?,?)"

I have an XML file and I have a function to which this XML is passed as string. I have loaded this string in Xmldocument and I need to insert few children nodes under one node. This function returns the modified XML string. I want that whenever this function is called, new child nodes are added, currently, It adds child nodes once.Do I need to overwrite the XML file ? If so, How can I replace the node with new node ( with new child nodes added) so that It has child nodes added before the function is called again ?
My code looks something like this:
Dim doc As New XmlDocument
doc.LoadXml(applicationXml)
Dim parentNode As XmlNode = doc.GetElementsByTagName("prList").Item(0)

I am using ADO.NET Datasets in my VB Applications. I have a typed dataset with one Parent table and many child tables. I want to generate Identity Key when I insert data into Parent Table and then update the data in all child tables with the Same key (As Foregin key).At last, I want to update the dataset in Database(SQL Server08).Well, the above thing can be possible by first inserting Parent Table in Database directly, get the Identity column and than use to for Child tables.

I am not sure I am getting the concept of referencing nodes in a treeview. When I hard-code nodes like:
tnParentNode = New TreeNode("ABC")
tvReports.Nodes.Add(tnParentNode)
tnParentNode = New TreeNode("Some Other Company")
[code]....
I get two parent nodes and one child off Some Other Company. However, when I pull information from a couple of tables to set up the parent and then the child nodes, I only get the parent nodes.So I pull the main parent nodes from one table and the child nodes from another table.This code pulls the parent nodes without any problem:
strSQLText = "SELECT lID, sCatName FROM Category ORDER BY iSortOrder DESC"
reader = GetReader(strSQLText)
While reader.Read
[code]....
But this does not add the child nodes. I am assuming it is because of the first line in the above reader.read while loop. I must not be referencing the proper parent node but I am not sure how to do it.

I have a treeview. The root nodes have images set at 30x30 - is there a way to add child nodes with NO image or a smaller image? I can do a blank image, but each child is spaced far apart! I would like the child nodes to be like there is no image... tight and close to each other.

I i'm attempting to add child nodes to a treeview inside a background worker's doWork() method.
I'm getting an exception because I'm in a different thread, and need to use the invoke() method.
Can anyone point me in the right direction?

I am having trouble adding a row to a databound datagridview on a parent form from a child form. I have two forms, one contains a datagridview that is bound to a table using 'datagridviewbindingsource' and contains an 'add' button. The second contains a checked listbox that is populated correctly and has a "Cancel" and an 'OK' button - when i check several items in the child form, i would like to hit okay and update the bindingsource of the datagridview on the first form with the checked items.
Code:
in form1 when btnAdd is clicked
dim f2 as new form2
'call it as a dialog to check for the cancel button
f2.ShowDialog()

I have a dataset that is being populated from a text file.
OrderNumber,Name,Model,Cost
123,john doe,product1,20.99
123,john doe,product2,10.75
There can be multiple of the same order number. In the dataset, I want to have a column "line number" and I want to put in it the value of the linenumber (in this case 1 and 2) per order. In sql , I was able to accomplish this by inserting rownumber() and grouping by order number. Can this be done in .net?

I have a piece of code that works for adding multiple rows to a dataset but I think that it is a lot of code and thought maybe someone may know a better way of doing it. I need to add rows to the dataset based on the selection of a combo box. ie if the user selects 15 the the program adds 15 rows to the dataset.
Case cboQty.SelectedItem = 3
Try
Dim dr As DataRow

I'm trying to add a new record in the DataSet in the master table. I'm not including a value in the unique ID field because it is added automatically by the server. At the moment I add second new row it throw me an error �Column 'ContactID' is constrained to be unique. Value '' is already present.� Do I need to set value of id column manually? How?
da.Fill(ds, "tblContactsProfil")
daAddress.Fill(ds, "tblContactsProfilAddress")

How do I do this for a different dataset? I'm trying to rule out database problems so I made another one and added it, but now I need a table adapter for this one instead of the old database because it keeps giving me an error. I don't see any place to add them and I'm getting extremely angry at these databases.

I add a row to the DataSet using the following code:
Dim NewRow as DataRow
NewRow = gds.Tables("TitleDataSet").NewRow
NewRow("Title") = txtTitle.Text
NewRow("Local_number") = nubLocalnumber.Value
NewRow("Number_suffix") = txtNumberSuffix.Text
etc.
This code executes without errors but the bound DataGridView remains unchanged (without including the new row). Obviously I am doing something wrong or I am omitting a vital command. What do I need to do in order to make the new row appear in the DataGridView? I did not choose to bind the DataGridView directly to the database table because the database is selected by the user at execution time. Instead I bound the DataGridView to the DataSet. I included the command:L
dgvTitle.AllowUserToAddrows = True
but that did not have any effect.
Solved. Was missing the final command:L
gds.Tables("TitleDataSet").Rows.Add(NewRow)

i am making a table through vb.net code (htmltablecell, htmltablerow..) no this table populates with an sql query and works perfectly. but inside this table in one tablecell, i need to add a dropdownlist which shall require a completely differernt query and shall run on its own on each row. so the code is as follows
Sql = "..."
rd = ExecuteReader(SqlCnn, Sql)
Dim newcounter As Integer = 0
While rd.Read()
[code]....
the ??? in the code is where the dropdownlist shall get populated each time with its own datareader and while loop and query.

In a project, I have a dataset with two table adapters. Without warning while I was modifying one of them in design mode, I received this error. I have typed the contents of the dialog box exactly as they appear - so no additional information was given, and the error code was "-1".

I have a question about using writeXml. When I use this method, it writes to the specified xml file like this:
<safety><Incident>
<Name>Jason</Name>
<AGE>23</AGE>
</Incident>
<Incident>
<Name>Frank</Name>
<AGE>25</AGE>
</Incident></safety>
But, I would like to add these nodes to a parent node, i.e.:
<safety><SomeNode><Incident>
<Name>Jason</Name>
<AGE>23</AGE>
</Incident>
<Incident>
<Name>Frank</Name>
<AGE>25</AGE>
</Incident></someNode></safety>
I am creating the xml by first creating a dataset (connects to an SQL db and runs a query, filling the dataset) and using ds.WriteXML(myPath)

I have two forms....Mainform is filled with controls that are databound to a datasource.....then I have a child form that is used to edit data from parent form.......the data that is displayed on the child form uses the Filter() method of the binding source to display data only for the customer selected......
The child form has the standard OK and CANCEL buttons set up as dialog result.......after I edit the content in child form, the changes are displayed on the child form correctly......but when closing the child form and going back to the parent form the changes dont appear there unless I restart the application.....I also tried adding the tableadapter.update/fill method in the 'OK' dialog result event handler and it still doesnt work......
How can I make the changes take effect on the parent form without restarting the application?
