first: all questions on the forum are urgent.
second: I do not understand all parts of your question.
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.

Hi,
I have a MDI application and I want to get the child form which is currently in focus/on top/being used.
I've tried using logic like this to loop through all the MDIChildren:
<br />
array<system::windows::forms::form^>^ children = this->MdiChildren;<br />
for each (System::Windows::Forms::Form^ form in children){<br />
if(form->TopMost){<br />
System::Windows::Forms::MessageBox::Show(form->Text->ToString());<br />
}<br />
}<br />
</system::windows::forms::form^>
but it doesn't work.
|
|
|
|
|
I guess you should access the form's Active proprety
|
|
|
|
|
What you're looking for is the ActiveMdiChild[^] property of your MDI parent form.

Hi,
I have to run a C# windows service in .net in which i have to generate popup message box reminder every one hour. i dont want to run it as a application, as each and every time we have to run it manually daily. i cant find a message box in windows service. can anybody please give me an idea of how to do it in an automatic service so that no manual process should be done. once they switch on the system, the service should start automatically and should generate popups once an hour. Pls help.
Thanks and Regards

Erhm, too bad... You have to find another solution... A Windows Service does not support a GUI. You may want to develop a diffrent application which does support GUI (WinForms app.) and start start using the Process.Start() method from your service.
|

Maybe, just maybe, you can program something like a NET SEND command ? That shows 'like' a messagebox.
