Don't think you can do font size :/
I was doing tool-tips for an inventory in a game I was making, and the best I could do was making a semi-transparent form that appears relative to the mouse X/Y co-ords on Mouse_Over :/
Soz :/

Hi Vijay,
Please know that the detault checkBoxes in DataGridView does not have any property to check whether the checkbox is in Checked/Unchecked state. However, on the basis Value property we can check the state in the following manner:
BEGIN CODE
Dim flag As Boolean = False
flag = Me.DataGridView1.Rows(3).Cells(9).Value
If flag = True Then
MsgBox("State is Checked")
Else
MsgBox("State is UnChecked")
End If
END CODE
Hope this helps .

I am trying to use .NET delegate to make the form responsive while doing data retrieval.
The form contains lots of controls including a tabcontrol with tabpages.
When i Click the Search Button to retrieve the data, i invoke the LoadRecord Delegate and the RetrieveRecord Method was called, but when i click the next Tab Page the form hangs. Can anyone help me with this?
Heres the codes..
frmBase
Code Snippet
Private Delegate Sub LoadRecordDelegate()
Private LoadRecord As LoadRecordDelegate
Protected Sub ExecuteRetrieveRecord()
LoadRecord = New LoadRecordDelegate(AddressOf RetrieveRecord)
LoadRecord.BeginInvoke(LoadCallBack, LoadRecord)
'Retrieving
End Sub
Protected Overridable Sub RetrieveRecord()
'Override this
End Sub
Private Sub LoadCallBack(ByVal result As IAsyncResult)
LoadRecord.EndInvoke(result)
'Done Retrieving
End Sub
frmMyForm
Code Snippet
class frmMyForm
Inherits frmBase
Protected Overrides Sub RetrieveRecord()
Me.SearchRecord(ReferenceNumber)
End Sub
Private Sub SearchRecord(RefNum as String)
'Some Codes to retrieve information based on the RefNum
'Populate the controls(textboxes,comboboxes,etc.)
End Sub
private sub BtnSearch_CLick
mybase.ExecuteRetrieveRecord
end sub
End Class

Hi,
seems to me you are making illegal cross-thread calls, i.e. accessing Controls by a
thread other than the one that created the Controls.
You can try this in .NET 1.x, or in later .NET versions provided you disable the
cross-thread checkking. Anyway it is the wrong way of doing things, it normally results
in a non-responsive or hanging GUI.
The right way to access Controls from an arbitrary thread is by using Control.InvokeRequired
and Control.Invoke; there is documentation and lots of examples everywhere.

first: all questions on the forum are urgent.

You start to print, request data and than print the data?
Is that your problem?

By keeping track of where you drew it and handling mouse events so you can redraw it.

Well, it's hard to know what you're doing wrong if you don't post the code.

I am using VB2005 to write an addin for Autodesk Inventor 2008, and I am having trouble understanding one part of the code that I have seen is some sample addin's posted by Autodesk.
When an addin loads it gets access to the running instance of inventor, thru an Activate method.
Public Sub Activate(ByVal addInSiteObject As Inventor.ApplicationAddInSite, ByVal firstTime As Boolean) Implements Inventor.ApplicationAddInServer.Activate
' This method is called by Inventor when it loads the AddIn.
' The AddInSiteObject provides access to the Inventor Application object.
' The FirstTime flag indicates if the AddIn is loaded for the first time.
' Initialize AddIn members.
m_inventorApplication = addInSiteObject.Application
When I create a form in the designer I believe I want to access this same running instance, so I declare a variable. How do I assign the invApp variable the same inventor application from the Activate method?
I feel there is something very basic here that i am missing.
Imports Inventor
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim invApp As Inventor.Application
End Sub
End Class
If anyone can answer or direct me to something that will help me understand this.
Greatly appreciated

this is a member variable, you should access it directly from your form. I see no reason for it not to be static, there will be only one.

I have a datagridview. I want to allow users to right click on any record. When they right-click, they will get options like Add/Delete...etc.
Can you provide a sample code or external link to an example in c#?

Hi,
In order to achive the desired behavior you need to add ContextMenuStrip on the form. Then you need to add the MenuItems for the context menu and write code for the respective MenuItem (i.e., for Delete or ADD). Then you can attach the ContextMenuStrip to your grid on FormLoad (or any other event as per your requirement) in the following manner:
BEGIN CODE
this.dataGridView1.ContextMenuStrip=this.contextMenuStrip1
END CODE
I hope this helps .

have a textbox and in that i want to disable copy paste option of the user in window application using vb.net. Please let me know the solution

You will need to handle keyboard events such as KeyDown/KeyUp and/or KeyPress. In the event handlers check if ctrl+v or ctrl+c is pressed. You will also need to make sure that user can't open context menu of the textbox.
