I have a method (name=HelloCSharp.Rand(), see below "QUESTION HERE") that's uses "uint" as parameter and return type - therefore not CLS-complaint and I was expecting a compiler error. Problem is, there was NOT a compiler error (or error of any kind)... THanks.
namespace SomenameSpace
{
using System;
public class NukeIt
{
public NukeIt(){ }
//NO PROBLEM HERE: This method NOT CLS-compliant and generated a compiler warning as expected.
public uint Rand(uint nSeed) {return nSeed;}
}
class HelloCSharp : HelloVB
{
public HelloCSharp()
{
}
public override void Hello()
{
base.Hello();
Console.WriteLine("Hello, C#");
}
public new int Add(int val1, int val2)
{
return val1+val2;
}
//QUESTION HERE: "uint" is NOT CLS-compliant and should generate a compiler warning, but, it did NOT??
public uint Rand(uint nSeed)
{
return nSeed;
}
[STAThread]
static void Main(string[] args)
{
HelloCSharp hello = new HelloCSharp();
hello.Hello();
}
}
}
Thanks!

if your code is cls compliant, it means that ANY .NET language can run your code, but if it is not CLS complint, i.e. uses features only available in C#, then only C# applications can run your code.

I can populate a dataset and create a datagrid, but now it is time to do something with it.
I have a datagrid which shows a list of contacts. I want to be able to click on a row and have it execute a method. ( open a new form to edit the contact )
Are there any tutorials, or quick times one could advise?
Thanks!

Thank You, that is a great reference.
This question is related. I can get the CurrentRowIndex, but I would like to get a value of one of the cells instead.
<br />
txtCustomerID.Text=this.dataGrid1.CurrentRowIndex.ToString;<br />
I would like the text box "txtCustomerId.Text" to reflect colume "CustomerID" in dataGrid1
|
|
|
|
|
i think my problem was that i need to refer to the data set instead of the data grid.
i just declared my data set globally so i could access it anywhere.
<br />
txtCustomerID.Text=ds.Tables["Contacts"].Rows[this.dataGrid1.CurrentRowIndex][0].ToString();<br />

Hello,
Does anyone know of a method to keep the .NET Framework updated automatically/programatically similar to how Windows updater works?
I know that dotfx.exe can be downloaded and ran, but this cotains a large amount of files. If there anything at there that can detect just which files have changed and allow my program to install just those files?
Does C# have any built in functions to perform checks and updates on the framework?
Thanks

Dang! How much I wish Microsoft included an automatic update feature. Too bad there is nothing built in.
However, it wouldn't be that hard to check for newer versions on the local computer (just use the Reflection classes). I'm just not sure how to check for newer version on the internet. Maybe there is an RSS feed for MS product versions? Try looking for some resource like that

I found this article (http://windowsforms.net/articles/appupdater.aspx) on a .NET Updater Component that is also used in the .NET Terrarium game. This is one solution to keeping your app up to date, but doesnt look to be able to detect and keep the *.NET Framework* itself up to date.

I haven't looked at it yet. But, wow, that a neat feature. I looked at the older version earlier, and it didn't have that feature.

The dotnetfx bootstrapper (dotnetfx.msi) exactly fits your need, since only the .msi file is downloaded and run (small file), and then the rest is downloaded if required. There are articles on MSDN.
As a sidenote, dotnetfx[^] command-linez

The dotnetfx is a Redistributable, it is all of the framework. Not a small file.
And it does not update portions of the framework. Windows Update already updates
framework installs with patches and service packs and also has new versions of the
framework. A boot strapper performs checks at install time and if the framework
is not installed then it installs it. At least that is my understanding of it.

I think you should re-read my post.
I have made a clear distinction between dotnetfx.exe (the full redistribuable, >20 MB) and dotnetfx.msi (the bootstrapper, which is a small file).
May be dotnetfx.msi is not the exact name of the bootstrapper (I saw this a year ago, so I don't remember the actual name) but you get the idea.

Can you post a link to the dotnetfx.msi?

It's a merge module, whose name is dotNETFXRedist_x86.msm, which you can find in your install folder <installdir> \ Common7 \ Tools \ Deployment, as well as on the VS.NET CD1.
The trick is actually based on how you populate the setup (your .msi file) with merge modules.
Depending on it, you can check at install-time a module against a given version BEFORE the appropriate merge module gets downloaded or not from the net or any other location.

Now you are talking about something else.
You either have the framework or not. There is no way
to install part of it or update it. Thats Microsoft's job.
If you are talking about doing a Setup that downloads the required
files if they are needed, then if the framework is not installed
you are stuck downloading the 20 meg framework. But that is
different than what the original poster was asking.

There is no dotnetfx.msi. It is the msm you spoke of but it is
still a 20 meg file.

You don't get it. The .mcm file is only downloaded if a particular condition is true. Taking advantage of late downloading of .mcm files is a feature of Windows installer and only requires a particular use of the technology.
In my company, the setup team did exactly that for our products. It wasn't the dotnet merge module, but you get the idea.
To remind the list (something I wasn't sure of in the original post) :
dotnetfx.exe ==> 20MB (MS site)
dotnetfx.msm ==> 20MB (VS.NET cds)
dotnetfx.msi ==> does not exist. We are in fact more talking about the actual setup.msi, and it's your .msi file.
Good luck!

You are right. I have reread his post. I have certainly read the post too fast and it was first obvious to me the guy was talking about "how to download an upgrade to the .NET framework without including it in the initial setup files?".
Now if I get it right this time the question is "how do I upgrade from .NET 1.0 to .NET 1.1 by only changing the appropriate dlls?". Unfortunately, this is an invalid question. Not only the .NET frameworks are made to work on a side-by-side basis, the biggest issue the guy will encounter is that when MS builds the .NET framework, all assemblies have explicit and hardcoded dependencies, strong names, etc., so changing only a fraction of the .NET framework and expecting it to work is just wrong.
Of course, one thing to remember is that VTBL issues with function names, etc. are still a problem with .NET and cause breaking changes, just like with plain C code. With only one function name being renamed in one of the dlls, you'll get a wild and wonderful .NET framework exception next time some code tries to call that function (function that won't be found, obviously).
So no, it is not impossible to upgrade the .NET framework incrementally.

I need some help with creating an image icon (to be used in a menu) from a string. I need to do this cause I must support multiple languages, so just painting an icon won't be sufficient.
Does anyone have a good suggestion of the best way to do this? It needs to fit into a button of a pre-specified size.

The only way I can think of is to:
1) Make stream(with binaryreader - to read a file - and memorystream - memorystream reads from binaryreader) of data.
2) Create bitmap of this stream(System.Drawing.Bitmap.FromStream).
3) Create a handle to an icon from bitmap(bitmap.GetHicon)
4) From HICON, create Icon(System.Drawing.Icon.FromHandle)
Yes, that should be a solution, not knowing if it is the fastest

Hi all,
Can anyone tell me how I can trap the event of minimizing and closing a C# windows appliction? I'm only referring to when the user hits the minimize or close button on the form's control box. I need to set a flag for my application to do something when this event occurs and I'm not sure how.
Thanks
