hi all,
txtcaseNo.DataBindings.Add("number", dset13, "case");
txtrentstart.DataBindings.Add("date", dset13, "rentstart");
txtrentend.DataBindings.Add("date", dset13, "rentend");
txtrentduration.DataBindings.Add("number", dset13, "rentduration");
cmbCOHour.DataBindings.Add("date", dset13, "COHour");
txtcurrencytype.DataBindings.Add("text", dset13, "currencytype");
txtdailytotap.DataBindings.Add("number", dset13, "dailytotal");
txttotal.DataBindings.Add("number", dset13, "total");
this code gives an error like this: cant bind number ?
my database fields are :
number, date/time, date/time, number, date/time, text, number, number respectively. how should i change the first properties in binding (bold parts)?
help please,
thanks in advance.

i think what ever u have witten in bold letters are data types of coloumns
of table but u should put controls property to bind there
like if txtcaseNo is text box then data binding should be
txtcaseNo.DataBindings.Add("Text", dset13, "case");
where Text is text property of textbox to be bind.

I don't know if this is the right board for this, if not I'm sure someone will tell me.
I am developing a C#.NET application for the market, which will be sold over the internet by making a trial version (with limits on facilities and use time) available free, and providing an unlocking mechanism on receipt of payment. All standard stuff - except I've never done it before.
Can anyone recommend a good guide to how to do this, or even a developers' toolkit for generating/recognising keys and all that stuff.

hi all,
i have a few textboxes and a datagridview.
SelectionMode is 'FullRowSelect'. when the selected row changes, i want to change the textboxes.texts to change according to the data in datagridview.
i have a code like this :
txtKullanici.Text = dataGridView3.Rows[dataGridView3.SelectedRows.Count -1 ].Cells[0].Value.ToString();
txtSifre.Text = dataGridView3.Rows[dataGridView3.SelectedRows.Count -1 ].Cells[1].Value.ToString();
txtSifreT.Text = txtSifre.Text;
cmbYetkiS.Text = dataGridView3.Rows[dataGridView3.SelectedRows.Count -1].Cells[2].Value.ToString();
in which event should i put these codes ?
help please,
thanks in advance.

Never worked with DataGridView, but after a quick glance at the docs I would say SelectionChanged sounds suitable.

Try this:
private void DataGridView1_RowEnter(object sender, DataGridViewCellEventArgs e)
{
if(DataGridView1.CurrentRow != null)
textbox1.Text = DataGridView1.Rows[e.RowIndex].Cells[0].Value.ToString();
}
Regards.

First : you must write a code in Managed C++ to wrap your Unmanaged C++ code.
Second : Use your Managed C++ Classes in your C# Code.

how to insert values from controls to different interrelated tables in database
-- modified at 3:28 Tuesday 6th June, 2006
|
|
|
|
|
The best way is to write a stored procedure and call it with the values from your controls.
What's the database ? Have you looked on the site for examples ( in the articles section ) ? What about msdn ? You can use google to search msdn by putting site:msdn.microsoft.com at the end

Hello!
I have the code below, but I really don´t know how to make it work in C#.
"Type" in C# is like "struct" ??
Should I use "ref BrouseInfo lpbi" in order to refer to my "struct" or "Type" in the SHBrowseForFolder calling and/or declaration???
Const BIF_RETURNONLYFSDIRS = 1
Const BIF_DONTGOBELOWDOMAIN = 2
Const MAX_PATH = 260
Private Declare Function SHBrowseForFolder Lib "shell32" ( _
lpbi As BrowseInfo) As Long
Private Declare Function SHGetPathFromIDList Lib "shell32" ( _
ByVal pidList As Long, _
ByVal lpBuffer As String) As Long
Private Declare Function lstrcat Lib "kernel32" Alias "lstrcatA" ( _
ByVal lpString1 As String, _
ByVal lpString2 As String ) As Long
'Tipo para def
Private Type BrowseInfo
hWndOwner As Long
pIDLRoot As Long
pszDisplayName As Long
lpszTitle As Long
ulFlags As Long
lpfnCallback As Long
lParam As Long
iImage As Long
End Type
nextcode :
Private Sub cmdSearchFolder_Click()
Dim lpIDList As Long
Dim sBuffer As String
Dim szTitle As String
Dim tBrowseInfo As BrowseInfo
'Personaliza a procura
szTitle = "Type the source folder for the search : "
With tBrowseInfo
.hWndOwner = Me.hWnd
.lpszTitle = lstrcat(szTitle, "")
.ulFlags = BIF_RETURNONLYFSDIRS + BIF_DONTGOBELOWDOMAIN
End With
lpIDList = SHBrowseForFolder(tBrowseInfo)
If (lpIDList) Then
sBuffer = Space(MAX_PATH)
SHGetPathFromIDList lpIDList, sBuffer
sBuffer = Left(sBuffer, InStr(sBuffer, vbNullChar) - 1)
'This is the Textbox
txtFolder.Text = sBuffer
End If
End Sub

Use System.Windows.Forms.FolderBrowserDialog
