if the user is logged in as you say, you must already have read the table to identify him, so you already know how to obtain data from a table.

hi
I have on the form a datagrid that user information is entered as a factor. Now I want to print the invoice. It is this good? Is how do I do?
|

Your question made no sense at all as written. You haven't given any coherent details about what you've done, how you've done it or what your code is supposed to do beside print an invoice.

I developed an application in C # where I have 4 text boxes and a datagrid with 4 columns and multiple rows and a button.
The button should generate an xml file.
I can create the xml file and write the data from text boxes, but not the DataGrid.
Anyone can help me?
At this moment i have this code:
In the button action
XmlTextWriter writer = new XmlTextWriter("teste.xml", Encoding.GetEncoding("ISO-8859-1"));
Writer.Formatting = Formatting.Indented;
// for the textboxes:
WriteStartElement("textbox1");
WriteElementString(textbox1.text);
WriteEndElement();
WriteStartElement("textbox2");
WriteElementString(textbox2.text);
WriteEndElement();
WriteStartElement("textbox3");
WriteElementString(textbox3.text);
WriteEndElement();
WriteStartElement("textbox4");
WriteElementString(textbox4.text);
WriteEndElement();
WriteStartElement("textbox4");
WriteElementString(textbox4.text);
WriteEndElement();
For the datadridview xml output strutured shoud be like this:
<Tabela>
<Tabela-Linha numero="1">
<Id>01</id>
<Nome>Teste1</Nome>
<Cargo>xxx</Cargo>
<Extensao>500</Extensao>
</Tabela-Linha>
<Tabela-Linha numero="2">
<Id>02</id>
<Nome>teste2</Nome>
<Cargo>xxxx</Cargo>
<Extensao>501</Extensao>
</Tabela-Linha>
</Tabela>
Can anyone help me?

How about foreaching the <a href="http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.rows.aspx">Rows</a>[<a href="http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.rows.aspx" target="_blank" title="New Window">^</a>] collection of the grid, writing the contents of all the <a href="http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.columns.aspx">Columns</a>[<a href="http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.columns.aspx" target="_blank" title="New Window">^</a>] using the method you already used?
object value = dataGridView1.Rows[RowIndex].Cells[ColumnIndex].Value;

How about using a serializable object as the datasource for the grid then serialize the object?

Does .NET Framework 4.0 have every thing in it that .NET Framework 2.0 has. If I have a program that worked on .Net Framework 2.0 will it necessarily work on .Net Framework 4.0.

And to be safe you really need to fully test it.

Microsoft has a very good track record when it comes to backward compatibility. So, it must work barring some minor issues. Check the link in the first answer for known issues.

Mostly, but some things have been obsolesced, which makes developing for multiple versions difficult.
One example:
Reader = new System.Xml.XmlReaderSettings()
{
ValidationType = System.Xml.ValidationType.Schema
,
# if DotNet_2_0 || DotNet_3_0 || DotNet_3_5
ProhibitDtd = false
# endif
# if DotNet_4_0
DtdProcessing = System.Xml.DtdProcessing.Parse
# endif
,
XmlResolver = new System.Xml.XmlUrlResolver()
{
Credentials = System.Net.CredentialCache.DefaultNetworkCredentials
}
} ;
And unfortunately there are no built-in macroes defined for the version so you have to define your own.

Hi Guys,
I have a PictureBox control in a WinForms application where I need to display the image at the maximum height allowable by the screen size without changing the image's height to width relationship.
The Picture box is docked to the right of the form. Setting the image height is easy enough but calculating the width is problematic as screen pixels aren't square.
How can I calculate the width with the image displayed to it's maximum height without distorting the image? I don't know the actual screen measurements; only the resolution.
Thanks......

Have you tried setting the PictureBox's SizeMode property to Zoom??
|
|
|
|
|
I don't think you can unless the height to width ratio of the picture box exactly matches that of the image. Your resulting image will either be distorted or too wide/narrow for the picture box. This article[^] explains the issue and offers a solution which may help you; the code is C++ but should be easy to understand.

PictureBoxSizeMode.Zoom will perform an isotropic rescale such that the image fits one or both dimensions of the PB without clipping.
MSDN explains it rather well here[^].

Thanks; isn't it just so easy in C#?

Thanks. The solution shown in the C++ article shows how to size the image and then it's just a matter of setting the PictureBox ClientSize to the image size. This seems to size the image correctly and maintains the ratio.

And, as Luc pointed out above, the PictureBox looks after things automatically.

Yeah, it's about the only useful feature it offers.
I can't understand why people insist on painting on top of a PB, then find it difficult to correlate mouse location with picture pixels.

|
|
|
|
Probably because they don't make proper use of the documentation.

Hi All,
I have an array of UserRights (class that holds the rights for an individual table) called arrTables and an array of controls called arrControls (10 of each type of control needed). The arrControls are displayed/listed on a Windows form (TableName, ViewRights, EditRights...) so that the data for 10 tables can be viewed at one time. I've bound the data to the form controls using the following code:
for (int iLoop = 0; iLoop < 10; iLoop++)
{
ctrlQAControls[iLoop, 0].DataBindings.Clear();
ctrlQAControls[iLoop, 0].DataBindings.Add(new Binding("Text", arrTables, "TableName"));
currencyMgr.Position++;
}
When I try and display the form to the user data from the 10th table stored in the arrTables array is displayed in all 10 sets of controls. I learnt that the CurrencyManager holds the value of the Current possition and that is the reason for these results.
Is there a way around or an alternative way to implement this without hacing to use a datGridView or other list control?
Thank you

It sounds as though you should be using a view of the data instead of binding to 10 different datasource all at once.
But since you appear to want 10 seperate data navigations going on at the same time you'd use 10 BindingSource objects, each having its DataSource property set to the table you want it to navigate over, then set each controls DataSource property to the BindingSource it should be using.

Hi Dave,
Thank you for your reply. I've attempted to follow the steps above only the array of controls doesn't have a DataSource method, so I'm unable to set the DataSource of the controls in the array to a BindingSource. Here is what I have:
BindingSource bs1 = new BindingSource();
bs1.DataSource = arrTables;
ctrlQAControls[0, 0].?!?;
Could you tell me how I would go about assigning each controls DataSource property, in the array to a given BindingSource?
Thank you
