1. Add a "Key Press" event for the text box.
2. And add the below code in the Key press function
if(!char.IsLetter(e.KeyChar))
{
e.Handled = true;
}
This solution ll help you not to enter any integers in the text box.
Thanks & Rgds,

I have a UserControl that contains a collection of custom controls that inherit from Panel. I have configured an ActionItem to display the collections dropdown list (which opens the collection editor when clicked). I also have an ActionItem (property) which displays the current count of the collection. Everything works OK and I can Add and Remove items using the collection editor and the count field gets updated. However, when I create a designer for the child control, which inherits from ParentControl designer you get this stange problem. Adding controls using the SmartPanel option updates the count OK. Removing controls the first time updates the count OK. After that the SmartPanel will refuse to refresh. Calling the DesignerActionUIService.Refresh() method has no effect....I am stumped! If I change the designer to inhertit from ControlDesigner instead of PareControlDesigner it works fine but I need to be able to add controls at design time....help anyone?

There have two form which is form1 and form2.
In form1 user have to keyin the right password which we give them. If user keyin in teh textbox the password and click (OK button).If the password is same with the password we set.They can link to other form.
FOR FORM1:
private void textBox1_TextChanged(object sender,EventArgse)
{
// The password character is an asterisk.
textBox1.PasswordChar ='*';
// The control will allow no more than 4 characters.
textBox1.MaxLength = 4;
//
}
private void button1_Click(object sender, EventArgs e)
{
Form Other = new Form2();
Other.show();
}
*****What should I add in this two object so that:
1: In textbox keep user input
2: Verify in OK button object with our password to log in to form2.
TQ VERY MUCH.....

I assume the following.
You want the user the enter the password in one form.
If the password, matches with some default/inbuilt/from the database password,
then it should go to the second form.
I also assume that you have a default password stored for comparison.
We'll Here it is.
You have to validate the password in the same form.
Form1 fm1 = new Form1();
Form2 fm2 = new Form2();
string DefaultPassword = "pass";
string PasswordCharacter = textBox1.Text;
if (PasswordCharacter==DefaultPassword)
{
fm2.Show();
fm1.Hide();
}
I hope this helps.

Just put a check to validate the user entered password with the default password. If both are same, the show the form2. Thats it..
public partial class Form1 : Form
{
Form2 form2 = new Form2();
public Form1()
{
InitializeComponent();
Password.PasswordChar = '*'; //Masking Char
}
private void Form1_Ok_Click(object sender, EventArgs e)
{
string strDefaultPassword = "ABCD"; //Keep ur default passowrd
string strEnteredPassword = Password.Text;
if(strEnteredPassword == strDefaultPassword )
{
this.hide();
form2.ShowDialog();
}
else
{
MessageBox.Show("Wrong password entered");
this.Close();
}
}
}
Thanks & Rgds,

Hi
I have a DataGridview control. I want that, when user enters in NewRow I fill some cells with default values and Focus on costum cell. But i got an Error :
(Operation is not valid because it results in a reentrant call to the SetCurrentCellAddressCore function.)
And my code :
<br />
private void dGridViewWork_RowEnter(object sender, DataGridViewCellEventArgs e)<br />
{<br />
if (e.RowIndex == dGridViewWork.Rows.Count-1)<br />
{<br />
dGridView.Rows[e.RowIndex].Cells[0].Value = "1001";<br />
dGridView.Rows[e.RowIndex].Cells[4].Value = true;<br />
dGridView.CurrentCell = dGridViewWork[1, e.RowIndex];
dGridView.BeginEdit(true);<br />
}<br />
}
An error refers to the line that Focuses on Cell[1,x].
Can you help me? Tanx.

I did not get what you meant by that exactly.
Still assuming that you are trying to access the row 1.
By default you can access only the 1st (0th row).
i u want to access, you need to add more rows.
else you will get error when you refer to the first row, or any cell from that row, i.e. Cell[1,x].
Still please tell me more about it.

Hi and Tanx
Dear friend Cell[1,x] means Cell[ColumnIndex,RowIndex]. I know it's funny but when we want to set CurrentCell we first type columnindex.
For example imagine we are at Row number 6 (Last Row) and user press Enter key. DataGridView create new blank row, Now i want to set First Cell's value to 7 programmatically and automatically move cursor to Second cell, then goto input mode . But there is an Error in focussing to second cell in 'RowEnter Event'.
Please Help.

Finally i found the solution to my problem so i am sharing the solution here.
The values that are printed on the report can be accessed from the code by this code.
CrystalDecisions.CrystalReports.Engine.ReportDocument a = new CrystalDecisions.CrystalReports.Engine.ReportDocument();
str value=a.Rows[0][20].ToString();
The Rows property contains the data on the front page of the report.

Is it possible to convert a .mdb (MS Access) file to a binary file? I tried to find a solution/converter for it but was not able to do it.

Yes.

You didn't say what sort of binary file. Keep in mind that an mdb file is a type of binary file too.
|
|
|
|
|
A kind of serialized, sequential-access textfile which can be used together with FileStream for example.
|
|
|
|
|
Well, that's not a binary file. Do you want to export some data to CSV?

I'm not sure if that is possible except in the 2007 Microsoft Office System - Microsoft were touting that kind of functionality at their roadshow so I'm guessing it's new.

http://regexlib.com/Search.aspx?k=ip+address
code below matchs ip
string RegString = @"^(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9])\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9]|0)\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9]|0)\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[0-9])$";
Regex RegObj = new Regex(RegString);
if (!RegObj.IsMatch(ipString))
MessageBox.Show("error", MessageBoxButtons.OK, MessageBoxIcon.Error);
|
|
|
|
|
This will match the pattern of an email address using a regex expression:
public bool EmailValid(string email)
{
string _expression = @"^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}" +
@"\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\" +
@".)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$";
return System.Text.RegularExpressions.Regex.IsMatch( email, _expression );
}
Hope this helps
