hi friends,
i want to insert value in a particular column of a row(datagridview) from a text box.
please help!

Sorry, but your question is not clear enough. Do you mean put the text from text box into grid?
In that case you can just access that particular column of the datagridview and then set it.
The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it.

I was curious, I work for a PC repair shop, and we use alot of applications to get certain jobs done, but I also have a certain amount of applications that I use for OS Support, is there any way to deploy applcations we use using the Deploy and Package wizard to install it on out customers computers, for example, adding Malwarebytes dotnet4 and java offline installer in a deployment package?

Have a look here[^]. This link describes how to use custom file types while creating a setup.

Hi,
I am trying to make a kind of desktop widgets using C#. So far, I've managed to create a window that gets added to the WorkerW window containing SHELLDLL_DefView. This way, my main form is inserted inside the desktop window over the wallpaper. This is exactly what I want except that I have a little problem. It seems like there is an opacity of 50% and a black is rendered as transparent. I don't know where this comes from and I don't know if I can change it. Does anybody knows what might be causing this and how can I fix it?
The code I used to do this is pretty simple. I find the handle to the WorkerW window that contains the SHELLDLL_DefView window as a child and then I call those functions to insert my own form inside as a child :
SetParent(this.Handle, hWndParent);
SetWindowLong(this.Handle, -16, new IntPtr(GetWindowLong(this.Handle, -16) | 0x40000000));
Here's how it looks when the form is in the desktop
Thank you

If you are trying to create a desktop widget then do some research with the Sidebar Gadget projects. The way you are doing it could be problematic.

After creating a VB.NET app in .NET Framework 4 I noticed that when I try using the application on several levels of windows whether it be XP/Vista or 7 it keeps throwing an error bout installing the suggested framework on the computer. How do I compile it so it is compatible with several OS's without the user having to install the .NET Framework in order for it to run?
|

Sorry to tell you, but if you build an application in dotNET 4.0, any computer that will attempt to execute the application will be required to have dotNET 4.0 installed, there is no way around that as the dotNET 4.0 assemblies provide the "under the hood" functionality that your application utilizes. About the only way to be a little more backwards compatible would be to target your project(s) to dotNET 2.0 and refactor any code that requires it to run in that mode.

.Net 4 apps require .Net 4
However you could add the .Net 4 prerequisite to you installer package to ensure it gets installed before your app runs.
|
|
|
|

If you don't need the latest features, you could target say 2.0 AND somehow tell your code will also run happily on higher .NET versions (for the rare situation a system has say 4.0 and no 2.0). I don't know the details, uncle Google knows for sure.
ADDED
Whatever targets 2.0 also runs fine on 3.0 and 3.5, as these are functional and technical supersets of 2.0
4.0 is a completely different thing; it is a functional superset too, but consists of all new files
1.0 and 1.1 should be considered obselete IMO.

You need the right framework installed.
Or you could use multitargeting to compile your program in another version of .Net (provided you are not using features specific to .Net 4). But then you would still need that framework installed.

Target the runtime version which you think would be installed on all your target client OS.

Hi,
I have read many times that ADO.NET is disconnected architecture.
But the datareader object requires open connection while fetching that data.
Please share your views on this.

Methinks it requires an open connection while fetching, and that it's closed when it doesn't. So, by default the connection is closed, and only opened when required.

That really depends on how you set up the reader. Closing the connection isn't obligatory - good practice, but not mandatory.

True, but the question was about the disconnected architecture. Whether one closes the connection (and the reader) doesn't change the principles.
Yes, it depends a bit on the reader, it might have been initialized with the argument to close the connection once the reading is done. You might also want to keep an open connection for a second command that gets executed, but the idea behind the disconnected architecture is to close the connection when you're done.
That depends on the programmer, and is a best practice again. It's not mandatory, you can open a single connection for your app and keep it open for the lifetime of the application. I'd rather see it closed, or better yet, encapsulated with a USING statement.

In that one case, no, it's not disconnected. In other cases, where a dataset is returned or some other operation, yes, it is.

DataAdapters use DataReaders -- but they're smart enough to open and close the connection as necessary.
