Do you understood my Suggestion ?

Do you understand the Dave's solution , and my case ? I don't need to add handlers for each controls.
|
|
|
|
|
At first you need to use to KeyEventArgs from the Event. They telling you directly that (for example) the Shift-Button is pressed.
Then : you need to connect this method to each Control, which could have the Focus. And also to the Form.
|
|
|
|
|
1) I have enabled the KeyPreview property on the form.
2) after I've used this event :
Private Sub MyForm_KeyDown(sender As Object, e As KeyEventArgs) Handles MyBase.KeyDown, MyBase.KeyUp
If My.Computer.Keyboard.ShiftKeyDown Then
........
Else
..........
End if
End Sub
Only with these 2 steps, almost everything Is working. So when I'm on the form , I can focus any control , and if I press the shift button , the event is working.
The only thing that doesn't work is when a MessageBox is showing. After that , the event doesn't fire when I release the shift button.

The MessageBox is another Form ...
What about calling your method "MyForm_KeyDown" additional by a Timer ...?
|
|
|
|
|
And what if I release the shift key after the time is expired ?
|
|
|
|
|
The Timer repeats it's Tick as long as the Timer itself is activated.
So ... if you ask für the state of the Shiftkey you will get this Info by the next Timer.Tick
You only have to decide, which Timer-Intervall is the right value for you. I would suggest something between 100 milliseconds and 500 milliseconds.

Hello !
I'm trying to implement a Event Log on my vb.net Application + Sql server database.
I have an Event table that keep all the event that are happening when using the database , and where it's necessary the event record can contain link to the Table and record related with this event.
The idea is working , but I have 2 problems:
1) The Event table is growing very fast . Do you think it's better to keep inside my main database , or to move to another database ?
2) I need a suggestion about the events that are related to Deletions. Since I can't keep a link to these records ( because they are deleted ) , how can I inform the users about the deleted record related to this event ?
Thank you !

I'd put it in a separate database on the server, with its own backup policy. I'd also recommend to not broadcast "every" message, but to have the severity as a setting.

"Record X has been deleted". The only way to say what was in record X is by keeping a copy and not deleting it.

Can you explain this , because I don't understand it.
Thank you !

You are now sending multiple types of messages, and they flood your table?
If you don't need all those messages everytime, then you might want to consider to "not send" them until you throw a switch somewhere. As in, only get the messages you are interested in, when they are relevant.

Still I'm not clear what you are saying.
I store any kinds of events like :
- A new record is added
- A record is deleted
- A record is modified
- A report is created
- A database backup/restore is made
- A Import/Export is made
....
So for what kind of messages are you talking about ?
Thank you !
|

Any of the above. If you need all of those messages, then yes, you'll to reserve space for them.
Do you really "need" them all, all the time? Or could you live with the fact that "modification" messages are only sent if it was configured to send them?

I need them because the company's administrator want at any time to see what the users have done at a specific day or time.

Then it will become a large table; it works the same as with old fashioned books - if you are going to write a lot of them, they will require more space.

So , your final suggestion is to keep this table inside the main database , or to have another database that will keep only the Event table ?
|

That has already been answered.

Sorry , then maybe it's a misunderstand for me.
On your first post about my question , you wrote :
Quote: I'd put it in a separate database on the server, with its own backup policy. I'd also recommend to not broadcast "every" message, but to have the severity as a setting.
Now I don't understand , why we have done all this conversation with each other ? If I should use another database , why I should not keep all the events , as you have suggested ?
Thank you !

Hello,
I'm working on a Excel Add-in project in VSTO professional.
What I try to accomplish seems simple, but I cannot figure it out.
I have an excel XLL addin in resources.
On thisaddin.startup I save the xll file in folder in my documents.
What I want to do in the run time is to go and register/add this XLL addin to excel application.
Basically want to replicate following manual steps:
file->options>addins->excel addins->Browse to my folder--> add
Thanks a Lot!

CR is not installed by default, nor automatigally included. You'll need to add it to your setup as a prerequisite. Depending on what software you are using to build a setup that could be an MSI or a merge module.

Hi,
I've spent the last few days looking at approaches to creating a 3D display of data points (as a small sphere) and lines (linking the spheres & as a co-ordinate axis).
I did think that DirectX was the solution, but it appears to be not supported for VB.NET under the V4 .NET Framework (?).
So I have installed XNA v4.0 as this seems to be the 'new' way of performing 3D graphics.
My goal is to have a form with a picturebox or appropriate control that I can write "data points" on to in a 3D space. I also want the user to be able to zoom and pan to view the data.
I have had no luck finding straight forward examples in VB (I'm not a c# guy). I have found examples that write circles and lines to a 2D space using XNA but nothing more complex than that.
I would really appreciate any suggestions on where to find a good VB.NET resource for XNA. A post of some sample code would be even better !
Thanks in advance.
Regards
RS

Getting XNA to show in a WinForm is not a simple task; 3D graphics are not part of the Framework.
You could start here[^]. There's two more options, both "not easy". You could try and find a DirectX3D tutorial, or go for OpenGL[^] - which would have my preference, as it is available on multiple platforms.
