One has to include the .NET runtime as well as Installer support in an executable assembly for taking care of the machines which do not have .NET installed on it. This makes the program (to be distributed, say on Internet) size increase by a huge margin.
My question is - suppose the assembly is converted into native code before distribution, and is then distributed (either with or without Installer ; and either installed into the Catche or otherwise), will it still require to bundle .NET runtime for supporting machine which do not have the same?
So, the question basically is will an assembly converted into native code (using ngen utility) run on a machine which does not have .NET runtime installed thereon?
|
|
|
|
|
Yes, since ngen only works for the machine it is used on.
See, if you write a program and generate an image with ngen, you cannot simply "pass" that image along. Read the docs and you will see, what I mean.
But it might be sufficient to say that ngen-images depends on processor properties, operating system, version of the operating system, version of the .net-framework and so on...
Cheers Sid.

Does it means that the native code prepared on one machine cannot be distributed as it will not work on another machine due to the "image" problem?
If so, then is it possible to use ngen to create the native code at the time of installation of the assembly through a setup program on the client machine? Will the .NET runtime be required to be bundled together in the setup? And, will it be a big size setup / Installer program again?

Basically, the problem is that the images cannot be simply copied to other computers. So the anwer would be, yes, the .NET runtime has to be installed.
Think about it: The .NET Class Library is part of the .NET Framework. Now, even IF you could simply copy the NGEN-Generated images over, you still would need to
a) Work around the PE-Executable Format
b) Work around the missing Class-Library
c) Work around Windows not knowing what to do with your image
...
The runtime-installer is not too big. Many computers already have it installed as a part of regular updates, for example, WinXP SP1 or SP2.
This may be a problem if you plan to distribute your app as "download only", which would require you to warn people about the requirement and hint them as to where they can get the .NET FW (Microsoft / WindowsUpdate).
Remember, you only need the FW - and thats about 15 MB (if I got that right).
Cheers

hi,
As far as I have seen, there is no easy way to enter multiline text (while preserving spacing formatting, etc.) into a regular text box or rich text box. So I created an application that does this for you. You paste or enter your text into a rich text box, then click a button to generate the code with the formatting information (such as "\r\n", etc.). This is basically a way to batch convert your text into a format that can be inserted into another application to send that text programmatically into a regular text box or a rich text box. I hope you find it useful. You can download it here:

IXMLDOMNode nodefld1 =thisXDocument.DOM.selectSingleNode("my:myFields/my:field3");
nodefld1.text = obj2.ReadfileInfo();
where obj2 is a object of a web service , which return a string of base64
and field3 is a file attachment .

How do i make an msi project in visual studio .net be a silent install all the time?
|
|
|
|
|
It's not done in the project, but in the command line that launches the msiexec processor that runs your .MSI install. An .MSI is a database, not an application.
msiexec /q /i myApp.msi

I'm a C#/.Net newbie, so be gentle... 
I've added an MSChart control to my form and would like to populate it with data. My data is a single dimension (of size > 0) array of ints (eg: sales per region). I haven't been able to find any documentation on how to do push this array into the control and would appreciate a pointer.
(edit)
The "array" needs to be a dynamic collection of ints, a la an MFC CUIntArray. It will be populated (with approx 5-10 ints) just before I load the chart control. Looks like I have to a SetData() (i.e. set the control's Data property to point to my collection) but am stymied as to how to do this.
Sadly, this didn't work:
ArrayList counts = new ArrayList();
counts.Add (5);
counts.Add (10);
counts.Add (20);
counts.Add (15);
counts.Add (3);
axMSChart1.ChartData = counts;
(/edit)
Thanks!

Figured it out! It was as easy as:
double[] counts = new double[3];
counts[0] = 5.0;
counts[1] = 15.0;
counts[2] = 25.0;
axMSChart1.ChartData = counts;

Hello I need a little help.
I have three array lists for this example.
ArrayList one = new ArrayList()
ArrayList two = new ArrayList()
ArrayList three = new ArrayList()
I would like to do a foreach or for loop that can cycle through the items in the three Arrays. Instead of doing 3 foreach loops around my values like this:
foreach(int a in one)
{
foreach(int b in two)
{
foreach(int c in three)
{
get array valuse here
}
}
}
Hopefully that makes since. Thanks for the help.

There is no one liner for this problem. If you REALLY want it I have two possibilities:
1. Write an own IEnumerable implementation which takes theses three lists and then exposes an IEnumerator which can handle these after each other.
This only make sense if oyu are doing this really often.
2. Add all items to one list and enumerate over the merged list.

Do you want to do it the hard or the easy way?
The easy way would be to use the IE, which can sort of be loaded into your App.
The hard way would be using the HttpRequest, which can obtain files from a web-server. You then need to draw that.
Writing a simple browser is not too hard - getting things displayed the way they are supposed to be, however, is.
Cheers
Sid

okay...
Can you show me how to use the IE in my application?
I can load the file into the users internet browser, but thats not what I want.
Or
How to show the it using the HttpRequest, but the file I want to show, is only on the users computer, not on a server.

This often means that the file cannot be written to by the account that the code is running under. Check your NTFS permissions for the file and the folder it's in.
If the operation succeeds for the first attempt to open a connection but fails subsequently, it often means that Jet cannot write to the log file in which it tracks concurrent operations (a file with the same name but a .ldb extension, in the same directory).

I would like to write an application that overlays information on external application windows.
My plan is to draw the information on a transparent window that is positioned over the external application window. In order to do that I would like to track some information from the external application, like position, size and z-order so I can reposition the transparent window accuratly. Ideally I would like a way to read these parameters and get events when the parameters changes.
I would like to write my application in csharp. How could this be done? Is there a way to accomplish this using the .net API or do I have to use the native Windows API? Is there perhaps a simplier way to accomplish the same task? Does anyone have any references to source code which solves the problem (or a similar problem).

I found some Javascript code on the Internet and it works very well for what I need to use it for. I want to do the same thing in c# code. Does anyone know of a program that converts javascript to c# code? If not does anyone know how to run javascript from a c# program?

Look into these methods for running javascript from within your asp.net app.
RegisterClientScriptBlock()
RegisterStartupScript()

One thing you can do is compile the JavaScript code as JScript.NET (look at jsc.exe compiler in the DotNet SDK).
Once compiled as .NET code, C# code could call the JScript.NET functions without hassle.

Hello everyone. I have an interesting problem that I need help with. I'm sure someone else has already had this problem. I have a custom control (either win or web because I have both doing this) and this control contains other controls such as a label and richtextbox. Well I have a few public properties that set properties on the internal controls but I also have a property that exposes the internal control as a property. My problem is that when I goto the designer and set properties though the control exposed though the property none of the settings are kept, however if I set the properties on the exposed control in code behind everything works fine.
Any help would be apprciated
-Richard
