Hi,
It is very simple.
If you are creating the PictureBox at design time then u can just go to the
Properties window -> events tab and select the event that u want to handle

If you are creating them dynamically in the code then
just declare the events and define the methods which will handle the events

Just put the string in the javascript code.

Example:

var str = '<asp:Literal id="MyString" runat="server"/>';

MyString.Text = aString.Replace("\\","\\\\").Replace("'","\\'");

Hi,

I have created a user control with Checkbox attached to the textbox. As a control, enabling/ disabling checkbox will enable/disable textbox and I can set bool values to Checkbox and string value to the textbox.

I have added this control to the DataGrid to alll exiting rows and column. To refresh the values to the user I have override Refresh mothod.

But now the problem is, even if I change the value for any cell, it is updaing same value for all cells where the control is placed. So is it possible to change the value of single cell?

Hi friends,

Am having a grid with TextBoxColumn in it..There a combo is placed for selecting the value for the textboxcolumn...

My Grid looks more like a table in the design view of MS Access..
Similarly,there are 3 columns ..one for FieldName,sec for Datatype and third for description...

In Access,when we select the datatype from the dropdown list and move to the next row,the datatype wont change even if we move through various rows up and down..

In my appln,after selecting and moving to the next row,and again back to the prev row(to tht part col),the selected text in the combo changes to that row(tht col) from which v r moving..

Kindly help me...

Thanx...

I have an MDI parent form "formMAIN" with the following code:

public formMAIN()<br />
{<br />
  InitializeComponent();<br />
  // blah blah blah<br />
  LoginForm loginForm = new LoginForm();<br />
  loginForm.ShowDialog();<br />
<br />
  if (LoggedUserName != "")<br />
  {<br />
    this.Text += " [" + LoggedUserName + "]";<br />
  }<br />
  else<br />
  {<br />
    // problem area... I want to close the main form if login failed...<br />
    //   IE... LoggedUserName will be ""<br />
  }<br />
  ...

The loginForm connects to the database, checks for matching user name and password and sets the formMAIN's static variable "LoggedUserName" if a match is found. I placed it in the constructor of formMAIN so that it would appear first.

I want to be able to close this main form immediately if the user closes the login form or clicks the "cancel" button on it... IE.. LoggedUserName will be blank when the focus returns to the formMAIN.

I tried "this.Close();" as well as Application.Close(), but it doesn't work. I'm guessing this is because it's in the constructor for the form, which obviously is not yet completely instantiated. I can't put it in the initialize area for the same reason.

I need some way to automatically perform the this.Close() operation 'after' the formMAIN completes initialization if the LoggedUserName value is still "" (IE.. failed log-in or user canceled the login form). How can this be done with the least amount of code?

Try calling

Environment.Exit(1);

WARNING: I'm not sure if this is the right way to do it, but it seems to do the job. You might want to see if somebody else comes up with a better solution.

Cheers,

Try putting your code into the form's Load() event instead.

Isn't an ocx a COM control ? If so, you can reference it using COM.

Right click on the "Toolbox | Windows Forms" and select Add/Remove Items.
Select the COM Components tab at the top. If the activeX is registered on the system it will be in the list. Select it and you will find it in the Toolbox list.

You can use System.IO.Directory.GetFiles to find files in a directory, and a StreamReader to read a text file.
