Hi All,
This is my first message on this forum. I'm working on a project where i need to create custom installer class, which checks for .NET Framework and SQL Server 2005 before installing, if not found then i need to install the Framework and SQL Server 2005.

What i need to know is how can i check whether framework is installed or not(apart from checking in registry).. is there any way ??

If not installed then how can i install the framework while installing the application ??

Please suggest me a solution how can i achieve this ...

Thanks & Regards

Well, you can't check for .NET framework into an installer class: the class will need the Framework to run, so it will crash if there is no .NET installed.
To do what you want, look for Launch Conditions.

Right click on your setup project and press Properties, a window will open. Then, click on the Prerequisites button.
You will now see a list of packages that your application can depend to, check the ones you want to use and select Download prerequisites from the same location as my application to copy them in the output folder thogether with the msi file and Setup.exe.
If you have Sql Server installed on your machine you should have a Sql Server entry in the list, otherwise, look here.

Probably because not express versions of Sql Server are not freely redistibutable (you will need licenses for each machine on which you install it).
If your application is to be distributed on several client machines, then I suggest you to use Sql Server Express.

If you have problems with BMG, you should address them to this discussion page.

I assume you're talking about injecting?
If so, read this article:

http://www.codingthewheel.com/archives/how-to-inject-a-managed-assembly-dll[^]

and - you can create a dll in c# that just contains enums, which would give you a dll without any "classes"......

TcpListener.AcceptTcpClient OR TimeOut

It seems that I'm stuck on something small but I've been working on it for quite some time and I'm exhausted...

I have a method that returns a bool whether a TcpConnection was successful or not...

The method attempts TcpListener.AcceptTcpClient

however I want it to return false if no client has been connected within a specified time (e.g. 2000 milliseconds)...

How can I achieve this? I attempted the .BeginAcceptTcpClient and .EndAcceptTcpClient but these still block OR if I use the Thread.Sleep() I block the method from accepting any connecting client.. I need the result to be returned if a TcpClient is accepted or the operation 'timed-out' - whichever comes first. Please help!

something like this?

[pseudo C#]
private bool GetNext(out TcpClient client)
{
    client = null;

    while ((less than 2000 ms has elapsed) and (!TcpListener.Pending())
    {
        Sleep a bit
    }

    if (TcpListener.Pending())
    {
        client = TcpListener.AcceptTcpClient();
        return true;
    } 

    return false;
}

datagridview size

Hello,

I have a datagridview in my application.
I want to add an option that the user could resize the datagrid (table) as he wants (for example when the mouse is on the border of the datagrid, the cursor will change to resizing cursor and he could drag it (and so resize the datagrid).

How can i do it?

Most people arrange for the resize of the FORM rather than the control. If your DGV is set to dock.fill then it will be the control that expands when the form is resized.

OK, But i want the DGV to be resized inside the form. For example if the mouse on the border of the DGV, it's cursor will be changed to resizing cursor and the user could drag it to its new size.

There are loads of hits for this, on Google.

One of them was Allow the User to Resize Controls at Runtime[^], have a look and see if it helps.

So you have loads of unused/wasted space inside your form - I'd call this lousy design, a form should be reasonably tight with no wasted space on it.

Hi,
I used this tutorial : http://www.codeproject.com/KB/cs/ResizeControlsRuntime.aspx
I have below my DGV another control (DGV), but when i resize the first DGV (below the second DGV), the second DGV hides part of the resizes DGV (it's on top of it). I have a resize option to the second DGV too.
What can i do that the resized DGV will be always on top of all other controls (DGV)?
If i can't do it, what can i do so the first DGV will be always on top of other DGVs (when i resize it)?
