How to delete data in a table which multiselected rows from a DataGridView?
|
|
|
|
|
how is the grid populated ? If from a datasource, probably remove from the source and rebind.

I have been trying to add System.IO.Ports to VB 2003. I have tried using framework 2.0, but it won't let me and earlier versions don't have it in the System.dll. Anyone have any ideas?
Thank You,
Brian

Seeing as it was new in 2.0, it's not gonna be there in 1.1 or 1.0, right ?

Right. Can I add 2.0 to a VB '03 project? That is what I was wondering and if you can, I have tried and it won't let me. Wondering if I was doing something wrong.

No, you can't. .NET 2.0 classes cannot be used under .NET 1.x. You also cannot load two different versions of the .NET CLR into the same process. In order to use that class, you'd have to upgrade to VS.NET 2005 and .NET 2.0.
The other solution is to find a third party library for .NET 1.1 that implements Serial Communications for you.

I guess I will have to look for a 3rd party. I am adding functionality to an exsisting application.

Sorry, but here goes.
I have some controls on my form that show in the properties dropdown. But I can't find out where they are on my forms, so I can't seem to select them. If I try to delete their code from the designer -- big problems. How can I figure out how to select those controls if I can't find them on the form?
Thanks

Select them from the dropdown, then look at the location property to see where it is on the form. Try right clicking on other controls in that same location and choose 'send to back' if you have a need to select the control on the form, it's probably off the form, or it's covered by somethign else.

Thanks.
Yes, I did that already... the problem really is that I'm not even sure what form the lost control is on. Is it possible to retrieve that information from somewhere? I was looking for a controls.add line in the designer but didn't see it.

Sorry, I don't mean that I can't find which form it's on, but rather where on the form it is (which tabpage, within which splitcontainer?)
Thanks

OK, that I'm not sure of.

OK, thanks. I think I'll try to start deleting things until the lost controls disappear! Or if that doesn't work just rename them and keep them hanging around as ghosts. A strange situation that they can't be selected or deleted from the properties tab or somewhere.

hi
As i understood u have certain controls on page that u r not visible or u r not able to find them or its hidden below some other control.
In my opinion u can create a new form add the necessary controls on the new page and delete the old page.

Hi,
if you know the name of the Control you want to manipulate, you can:
1.
use the combobox to get to its properties, then change its location (say to 50,50)
to make sure where it will be inside its parent;
unfortunately I don't see Parent as a property, hence:
2.
read the designer-generated code add look for a XXX.Controls.Add(...ControlName)
to find out that XXX is the parent.
If you don't know the name and don't see it, you're out of luck. I then hope you will use
better names next time.

Thanks to everyone for the excellent suggestions. They really helped me.
I think that the code for the objects, which should have been deleted, still existed in the designer. However the controls were never being added to the form which is why I couldn't select them.
I was able in the end to get rid of them by editing the designer.

I have an client server application with SQL Server Express as backend database. The server application runs fine but when i run the client application, it hangs sometimes after 30 minutes and sometimes after 1 hour and so on. There is no problem with the code or the application itself but is there any known problem with the sql server express that freezes the application.
I appreciate even a bit of information because it is driving me crazy...

Also the client and server application runs in a different terminal(PC).

Obviously, you are wrong.

No.
If the client and server are on different PCs, perhaps your network has issues ?

Question: Why was God able to create the world in just 6 days?
Answer: Because he had no installed base to worry about.
I've been given an old VB6 application and asked to create a modern version. It has so few users nowadays that I don't have to worry about them. So I have a free hand (within reason) to build it using easiest tools available.
Almost an ideal project, so I want to start out right, and set a standard for future developments.
What is the best platform to work with? VS8 Is my preference, but do you agree? What gotchas should I look out for (I haven't used it a lot yet)
I assume best practice, even for a small business package like this would be ASP.NET, right? What about a package of controls, like Teleric? Do you think they are worth the money? Which one does the best job?
Finally, what about generators, like IronSpeed. Are they worth the investment (money and learning time)?
Any suggestions/Advice, please.

why ? Why is it best practice to move from a windows app to a web app ? It might be, depending on the app, but what makes you think that ?

Good question. The answer might be: Ease of installation, Ease of updating, Possibility of making it (easily) into a hosted solution.
What downside to Web/ASP do you see?
Thanks David

I guess you have to define the requirements and how it needs to behave. Does it require a rich and responsive UI? If so, then the desktop is still the best bet despite AJAX etc. Does it need to be accessible from multiple platforms? Then ASP.NET is the way to go.
Note that if you go the desktop route you can deploy it from the web using ClickOnce technology. So that takes care of the ease of installation and ease of updating bit. The only other restriction is that the client must be Windows.

Requires user to be online
dependant on bandwidth
UI not as rich
requires hosting

Is there a .NET equivalent to the PHP pack function?
