^Does that make sense?

Well anyway:

User clicks X, i ask if they're sure they want to close, they say 'no', how do i stop the app from closing at this point?

In your form, override the OnClosing method:

protected override void OnClosing(CancelEventArgs e)
{
   DialogResult result = MessageBox.Show("Sure you want to exit?", "Confirm", MessageBoxButtons.YesNo);
   if(result == DialogResult.No)
   {
       e.Cancel = true;
   }
}

Setting the e.Cancel property to true will stop the app from closing.

Session Variable Questions

Hi,

I am using session variables in .NET 2.0.

How do I loop through all the sessions variables to see what has been populated?

And how do I kill/destroy a specific session variable? Lets say I have declared a session variable like Session["MyName"] = "Ma"; and Session["MyLastname"] = "Se", how do I only destroy/and release back to memory Session["MyName"]?? I mean if I were to loop through all the session then it should not exist at all.

I hope someone can help soonest.

Regards,
mase

Session.Keys contains all keys for the session variables.

Use Session.Remove to remove a specific session variable.

Hi Ok, I'm filling my dataset. Next I want to know the row number of value at columns[0] that equals to somthing like 1001 (primary key).

Sample : myTable( Id  , Name , Phone )
      0:          1000, mark , 687668
      1:          1001, tom  , 436536
      2:          1002, jack , 564632
      ....

Now I want to get index (row number) of row in order to (Id=10001).
It should return 1.

Hello

Data rows don't have indexes stored in them. Yoiu will have to iterate thor DataTable.Rows one by one and get the index that you reach.

If you only want to get a reference to the row why not using DataTable.Select() method?

int count = 0;
foreach (DataRow dataRow in myTable)
{
if (dataRow["Name"] == "tom")
{
break;
}
++count;
}

count will return 1.

Very simple - took me so long to work out that the need for this indicates to me that it isn't the right way to go about coding but no one can tell me why?

pageBaseType Attribute

Hi,

I just have a query on this attribute, using .NET 2.0.

I have a BasePage class, which resides in the MyWebsite.Framework.BaseClasses namespace.

How do I specify this in the <pages> element, I'm not sure what the assembly is??

And how would the code behind page look like for an aspx page that uses this BasePage class?

Usually I would "import" this namespace and have that page extend from it, like so:
public partial class UpdateOrderItems : BasePage
{
}

I hope someone can help.

Hi,

I written a form application which is needed to activate when it receives a event from a hook procedure. the hook procedure sends the WM_COPYDATA message to my forms app. When I receive this message from hook I want my form app to be activated and shown to window. In the event handler of the message I tried to set the visible property of form to true, but it didn't work. Also Focus returns false.

How can I cahive this activating of application upon receiving the event?

Hello

If that's it then just like stancrm told you WindowState = FormWindowState.Normal should work! If not, try to add Activate() after it.

I thought WinXP doesn't allow anybody to hook the F12??!! Strange!

TabControl .net problem

Beast Forever21-Aug-06 1:36

21-Aug-06 1:36

Currently I am stacked from what Im doing. My problem is that I have a tabControl and inside the first tab, I want to have two divisions the left division (for menus) which comprises of buttons like button1 button2. Then on the rigth division displays the respective content for the button1 and button2.

For example, button1 when clicked, it will display a datagrid of a table. Then on the button2 once clicked displays a text box and a button etc...

Is this possible? What I want is to design those things at design time. Then I just called it. Is this possible?

If you could create me a simple prj like this or point me to a certain tutorial that is same as my scenario that will be great.

Please help, bec I cant start at all.

Hello

It's not just posiible, it's also easy with several ways.

1- Create you Menustrip, dock it to the left, make the text of each button vertical.
2- Make all your controls and put them in small sizes on the tabpage, you'll resize them later.
3- Set all controls Visible = false
3- Now, if it will be only one control at a time, handle the click event of each menu button, and on each button make all controls Visible = false, and Dock = None, except the one you want to show => Visible = true, and Dock = fill;
4- If it will be more than one control, put them all in a panel, or a group box, and handle the group box or panel just as in step 3.
5- Don't forget to initialize your tabpage with the first control you wish to view

This was just one way. Improvise!! Smile | :)

What do you mean excactly with 'like ICQ'?

Maybe you can use the msn API, or skype beta API? I don't really know if ICQ has an API too, maybe it has? Try a search on google...

Hello

You will have to use windows API to do this. The function is

::SetWindowPos(m_hWnd ,       // handle to window
                HWND_TOPMOST,  // placement-order handle
                rect.left,     // horizontal position
                rect.top,      // vertical position
                rect.Width(),  // width
                rect.Height(), // height
                SWP_SHOWWINDOW // window-positioning options);

search for how to handle unmanaged calls from C#, and dllImport.
