Hello,
is there a possibility to draw controls like in a graphic-program in layers? My problem is, that i want to have for example a panel with a transparent-png-file as background drawed over a button, but the button should be visible if there's a transparency in the png file. - and maybe for every control inside my form?
Is there any way to draw them without having the restrictions of the Panels and Controls and so on?
Many thanks

Hallo
I'm developing a C# .Net2 application built around a DGV.
Is it possible to have the DGV data refreshed automatically as the underlying data change?
I mean, is there any way to automatically PUSH changes from database to the grid (or the BindingSource)?
Thanks in advance

I have a no idea what a DGV is. You can create triggers in your DB, and I believe in newer versions of SQL Server, they can run .NET code.

I think you ment DataGridView Control by dgv??
If you are using dataadapter object you can easily reflect changes to db. All you need is a timer control, and calling update method of this adapter in Tick event of timer.

Well, that's not very efficient, I assume that's what he's trying to avoid.

By looking the question that he asked i think this method is adequate for this question.
I agree that this is not the best way and not very efficient but anything not mentioned about performance, or other ways that already tried.

hallo and thanks for the replies.
By DGV I mean the DataGridView control, but it could be any control showing data.
Actually I was trying to avoid a timer, but the underlying database is a SQL2000 thus having no possibility of CLR into T-SQL.
As far as I understand, the logic flow would be:
data changes > trigger that broadcasts/sends a message > client application "listening" > performs a grid refresh
|
|
|
|
|
Sorry I thought you were trying to send data to database. Now i understood you are trying to refresh grid from database.
data changes > trigger that broadcasts/sends a message > client application "listening" > performs a grid refresh is the best way i think
|
|

Yes, your outdated database probably means you have no choice but to use a timer. Unless, you write some sort of external app that broadcasts to all users somehow, when data is changed. It depends on how many users you have, how often data changes, etc.

I have maximum 15 concurrent users (on that particular table in the db) with less than 10 changes per minute: hence, I think I'll go for a timer.
Only, I thought that newer .NET brought something better on the argument...
Thanks anyway

It's your database that is out of date, and your database that is the issue. The database needs to tell your program when it's been changed, or you need to keep asking, those are the two options.

If your implementation utilises BindingSource there are several events that you should consider investigating.
BindingSource.CurrentChanged
BindingSource.CurrentItemChanged
BindingSource.ListChanged
The last of these is most likely to be of use to you.
Here[^] is a link to the BindingSource reference on MSDN. I am struggling along on 53.6 Kbs at the moment otherwise I would have given links to the events themselves. 
Hope this helps.

I want to gather the Mac address in the diffrent subnet.
Now,My programe(C#) can obtain the PC and Printer's Mac address by SNMP.
But i can not obtain the switches' Mac address by the programe.

Maybe there are some forbidden in my VLAN.it is right?

Hi,
I am working on shared add-in in c# for Excel. Let us consider 3 components A,B,C. Where A is a Shim,B is Shared an add-in(used IDTExtensibility interface) which creates all tool bars, menu items for Excel and C is an automation add-in which contains UDFs.
I have static property in Automaion add-in(C) which set/gets Excel Application object. Whenever OnConnection(..) of shared add-in is called from the framework, I am setting the Excel application object using this property. So When I type some UDF in Excel, it uses this Excel application object for further work on Excel.
Recently I tried to remove the Shim and put the VSTO on it. When I use VSTo, it doesn't use shared add-in.Here also I set the Excel application object by using static property. Now I have I enabled this Auotomation add-in(add-in->Options->Automation Tab).But when I type some UDF in Excel cell, excel object is not available that is set from VSTO.How do I pass reference to Excel object to Automation add-in so that the same Excel Object is available in Automation add-in when we type some UDFs.
What I observed here is VSTO and Automation add-ins are working in different AppDomains.
Please help me.
Thanks.

Hi,
I'm trying to get WebDAV implementation using some open source called Sphorium and Casinni Webserver. It is able to reach the destination folder but some time i'm getting the following error.
"Documents in this folder are not available. The folder may have been moved or deleted, or network problems may be preventing a connection to the server."
What could be the cause?

You are more likely to get an answer if you post in the correct forum. Try Web Development (look at the side-bar to the left for forums list)

Check Directory Browsing permission. You must set directory browsing permission to true. This will allow to get it a list of files/folders.
