Is there a way to code a ContextMenu so it looks like the Windows Start menu?
OK first how do you assign image to a item in menu so you see the icon and then text?

Hi
I develop a mobile device with a Touch-Screen (1024*768) with XP-Embedded. The application should be region/language independet.
The standard XP On-Screen-Keyboard is too small.
Can I manipulate the size of the buttons programmatically?
or
Is there a way to program a multi-language keyboard myself?
or
Does anybody know a good 3rd-Party-Tool/Library programmed in C#?
Thanks and best regards,
Martin

WHat would the coding be to open an XML file when the application loads?
its saved in the applications folder under Settings\\Settings.xml
In the end we're all just the same
|
|
|
|
|
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load("FILENAME.XML");

i write a function and i can not to call it
how can i call the fanction with btn_click.
private bool format(string date)
{
bool format;
if (date == "1384/04/03")
{
format = true;
}
else
{
format = false;
}
return format;
}
private void Button2_Click(object sender, System.EventArgs e)
{
date=txtdate.Text;
format(date);
}
|
|
|
|

The code you posted seems to be fine (it worked for my vs).
Could it be that the Button2_Click() Method isn't called.
Check the EventHandler for Button2 - there should be something like:
this.button2.Click += new System.EventHandler(this.Button2_Click);

i found the answer.
classname p= new classname();
p.format(date);

I have a button and the code on its this:
btnStartMnu.Image = System.Drawing.Image.FromFile("Themes\\WinME2\\WindowsMEButton1.bmp");<br />
Sound.Play("Sounds\\Camera.wav",PlaySoundFlags.SND_ASYNC);<br />
MessageBox.Show("Theme changed to Windows ME 2!", "Theme Changed");<br />
string appPath = Path.GetDirectoryName(Application.ExecutablePath);<br />
m_appSettings.Save(appPath + "\\Settings\\Settings.xml");<br />
m_saved = true;
When you click button, it changes its image and then saves the info in a XML file. What I want to know is how to add code so it will change the colour of a panel called pnlleft to red and panlright change its colour to yellow. How would you do this?
Also is there a way to change a fileMenu colours well?
In the end we're all just the same

|

Hey,
as long as you are in the same class you can simply use
pnlleft.BackColor = Color.Red;
(same with the other panel)
for the filemenu it is bit more complicate - the can only change the backcolor of one item - so the only way i know to change it all would be to go through every item.

Create a DateTimeFormatInfo for the calendar you are using. Use that in the DateTime.Parse or DateTime.ParseExact method to parse the date. Use try...catch to catch the FormatException exception that occurs if the string format is incorrect.

How do bind a data using DataReader?
|
|
|
|
|
Hi,
First build a connection string and then initialise the command and reader object as
Write this in the event when you want it to be done:(i have used MSAccess as database)
OleDbConnection conn=new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\new1.mdb");
conn.Open();
OleDbCommand cmd=new OleDbCommand("select * from Table1",conn);
OleDbDataReader rdr=cmd.ExecuteReader();
rdr.Read();
DataGrid1.DataSource=rdr;
DataGrid1.DataBind();
This is a simple example..
YOu try out for more samples..
Feel free to ask anything regarding this..

hi
try this:
1. open connection
2. SqlCommand objSqlCommand = new SqlCommand();
3. SqlDataReader objSqlDataReader;
objSqlDataReader = objSqlCommand.ExecuteReader();
objSqlDataReader.Read();
grid.DataSource = objSqlDataReader;
grid.DataBind();
objSqlDataReader.Close();
3. close connection

Hello everyone,
Greetings from Brazil! As shown in the code below, is it possible for me to add the new objects for tipoDT and sementesDT without having to do it one-by-one? Like, for example, getting the values automatically from the tables?.... How would I do that? The sementesDT table is quite large and would take me forever to add the new objects one-by-one! Here's the code:
public frmBA()
{
tipoDT = new DataTable("tabTipoSemente");
tipoDT.Columns.Add("CodTipo", typeof(int));
tipoDT.Columns.Add("Tipo", typeof(string));
tipoDT.Rows.Add(new object[] { 0, "Nocivas Probidas" });
tipoDT.Rows.Add(new object[] { 1, "Nocivas Toleradas" });
tipoDT.Rows.Add(new object[] { 2, "Sementes Silvestres" });
sementesDT = new DataTable("tabSementes");
sementesDT.Columns.Add("CodSemente", typeof(int));
sementesDT.Columns.Add("CodTipo", typeof(int));
sementesDT.Columns.Add("Semente", typeof(string));
sementesDT.Rows.Add(new object[] { 0, 0, "SubCat0-Cat0" });
sementesDT.Rows.Add(new object[] { 1, 0, "SubCat1-Cat0" });
sementesDT.Rows.Add(new object[] { 2, 0, "SubCat2-Cat0" });
sementesDT.Rows.Add(new object[] { 3, 1, "SubCat3-Cat1" });
sementesDT.Rows.Add(new object[] { 4, 1, "SubCat4-Cat1" });
sementesDT.Rows.Add(new object[] { 5, 1, "SubCat5-Cat1" });
sementesDT.Rows.Add(new object[] { 6, 2, "SubCat6-Cat2" });
sementesDT.Rows.Add(new object[] { 7, 2, "SubCat7-Cat2" });
sementesDT.Rows.Add(new object[] { 8, 2, "SubCat8-Cat2" });
InitializeComponent();
tipoBS = new BindingSource();
tipoBS.DataSource = tipoDT;
TipoComboBoxColumn.DataSource = tipoBS;
TipoComboBoxColumn.DisplayMember = "Tipo";
TipoComboBoxColumn.ValueMember = "CodTipo";
unfilteredSementesBS = new BindingSource();
DataView undv = new DataView(sementesDT);
unfilteredSementesBS.DataSource = undv;
EspecieComboBoxColumn.DataSource = unfilteredSementesBS;
EspecieComboBoxColumn.DisplayMember = "Semente";
EspecieComboBoxColumn.ValueMember = "CodTipo";
filteredSementesBS = new BindingSource();
DataView dv = new DataView(sementesDT);
filteredSementesBS.DataSource = dv;
}
Thank you very much for your attention, time and help and I'm looking forward to your reply.
Best regards,

What tables ? If you mean in a database, then yes, that's what a dataset is really for.
