How To Bind XML To Form Controls
May 2, 2012
I have the following XML file:
<?xml version="1.0" encoding="utf-8" ?>
<root>
<Language code="0" control="form" attribute="text">
<NL>Upload expansies</NL>
<UK>Upload expansions</UK>
</Language>
[Code] .....
I would like to bind the text between the NL or UK tags, based on a setting, to the control with the name in the attribute "control".
I started with this:
Dim xf As New Xml.XmlDocument
xf.LoadXml(My.Resources.Languages)
I am thinking I need to do something like a search in the xmldocument for the specific control, then get the text from the children.

I have a form called studentForm which has a studentCombobox, studentTextbox and a studentDatagridView
In the constructor of the studentForm I need to bind studentCombobox to the StudentbindingSource of the main form and to bind studentDataGridView to appropriate binding source in the mainForm.So that this datagrid view displays all the bookings for the studentID currently selected in studentComboBox
studentComboBox.DataSource = MainForm.StudentBindingSource
studentComboBox.DisplayMember = "StudentID"
studentDataGridView.DataSource = MainForm.StudentDataSet
studentDataGridView.DataMember = "Names "
This is the code I wrote in the constructor

I want to loop through all the controls on a "panel" and bind them to a datatable. I'm finding it hard to detect the "end of the panel" - as I also have group boxes and such on the panel. At first I was using the "parent" control - but that doesn't work with group boxes.

I've started to write an application in Visual Studio 2010 (VB) and I have trouble finding a way to create a button that starts a timer that after 3 sec displays next record of a database (something like slide show). I have a form with 3 textbox (id, field1, field2) and 2 buttons (start and stop).

I have a slight problem With an enumaration of child controls on a form. The following code will not get but about have the controls that are on the form. The controls show that the count is correct but when it goes through the loop it skips over some of the controls. If you run it through the enumeration two or three times it will get all the controls a few at a time. The solution uses two forms, one that has the controls and the other that labels are made and displayed on. The Tx is just a index to add a number to the label.name and rename the label. So each label is identified seperately. This works for all the the controls that are seen in the for each loop.

I am trying to bind data from a text box on my form to a field in my database table. First of all I have created a DataSet, BindingSource and Table Adapter in the forms Design view, but I am having from there. Under the properties of each text box I have set the DataBindings (Text) to the field in the table under the forms instance and DataSet rather than the Projects Data Sources. I am very rusty at Visual Studio 2005 and that is all I have to work with.

Using VB 2008. We have an app with a third party grid on it works well enough. This is a small utility within a bigger suite, and adding/updating it involves a simple EXE copy. The issue I am trying to address is that not all customers will have the 3rd party controls on their systems, and we want to avoid deploying them if we can.
Can I build the app so that if the controls are present, the app uses them. But if they are not present, I use a simpler control? I picture using a 'launcher' form that tries to load Form2 with 3rd party. if it errors, then just load Form3 with common controls. But can I even get to that point? With missing controls, will the app even load? I understand Late Binding for objects, but this is a control right on the form. Can I late bind a control and add it to form dynamically perhaps?

I have a module level sub that I use to clear text fields etc on my forms:
CODE:
The problem I have is in the last few lines of code as I'm not really sure how to access the text boxes contained within the tab controls (of which there are many tabs and many text boxes).
This is the closest I've got but I am getting an "option strict on disallows late binding" error on the tabCtl in the following line.

Inside a form, I would like to display a pdf file which is already available in my resources (template file "untitled"). In this pdf file, I have some fields which get their values from some texboxes in another form. My aim is, when the user triggers the button to call this form, it should insert the values inside the pdf file and display the output pdf inside the form.I have written the code to an extend but could not finish it myself after my many trials... Now here are the two things I cannot manage:I can use a directory to read the template pdf "untitled1.pdf". But my aim is to use the file inside my resources. can save the output file in a directory but this is not I want to do. I want to display the output pdf.

I'm currently developing an application with a reasonably complex DataGridView that allows the user to build the lines of a sales document: Quantitiy, Description, Price, etc with some additional fields to help calculate price based on cost or discount i'm sure you get the jist - all this means we're not just diplaying data but adding and manipulating it - It also means there's mainly decimal fields, nit just simple text fields
Now, i'm new to VB.net, so i've perhaps done things a bit backwards during my learning curve, namely designing and coding my DGV before creating the underlying database table and binding to it - so as i'm sure you can image there's a bit recoding to do to allow for the fact that it's now bound to a datasource.
I'd got the DGV working just how a wanted it to, but now that i've bound it to a datasource i'm hiting multiple problems with: Formating the appearance of figures in the DGV Problems with blank fields while enering data (before the i try to save the data back to the database) How the DGV is functioning - it seems to behave differently when adding lines to a new sales document than it does when adding lines to an existing sales document
And given that when saving edits to an existing line i need to provide a valid update command i'm begining to think that it might be easier to scrap the databinding altogether and just Select, Add and Edit the database with code rather than binding the DGV in the IDE
I've read various threads about avoiding databinding due to it's limitations, but i've also read that it's far better in later versions of Visual Studio and .net. and i'm using VS2010
I'd just like some advise as to whether my gut feeling is right or whether i should persevere with databinding the DGV. i've noticed some quirks of databinding while working with other controls such as text and combo boxes, but i've overcome these and the result seems to be easier than coding the data transfer manually.
But i'm really struggling with databinding the DGV and the fact that i'm dtatbinding to a seperate table to the rest of the controls is leaning me away from databinding
