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.

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

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.

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

[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)] makes sure it is saved - put that in front of your control property
|
|
|
|
|
if u have custom properties on that control property, be sure to use [DefaultValue(false)] on the properties if they are primitive types (int,string etc.).
If u have object properties use the [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)] attribute and go into that object and use the [DefaultValue(false)] attribute.
etc. etc.

I have an RTF which is being used do text editing. When an existing text document is placed in the control, it automatically adjusts lines based on the text fitting inside the window. However when I issue a editWindow.GetLineFromCharIndex() it returns a line number (3 for example) which is outside of the internal editWindow.Lines property within the control.
So line 3 may visually be the 3rd line of text. Yet internally all of the text only exists on line 1.
Is there any way to get the Lines property of the RTF to match the visual lines created via WordWrap???
Thanks!

I am new to C# and looking for a little help. I need to programmatically
add users "User Logon Name" / "WinNT logon" to the windows 2000 Active Directory. I need to control/add other properties, but for now this is the main objective.
I have successfully added pre-Windows 2000 users with DirectoryEntry & NetUserAdd, but can't find the syntax to add a WinNT logon name.
I am using Visual Studio.Net 2003
Thank you,
markaelkins@gmail.com
Other properties that I need to control/add: (password, Full name, pre-Windows 2000 logon, User cannot change password, Password never expires, Description, Office)

I have a progress bar. I would like to display a transparent label OVER the progress bar to show the % completed. It seems like all of the techniques related to creating a transparent label only make the label's background transparent relative to its parents background rather than relative to any sibling controls that might be draw UNDER it. Does anyone know of a way to draw a transparent label so that the text area of the label displays the content under the label rather then the background color of the parent container?
thanks.

A more appropriate way would be to extend the ProgressBar control and draw the label yourself. Putting a transparent control over it will require owner drawing anyway (to mask out everything but the text, which isn't easy if you want anti-aliased text) and will require more memory since another control is required (controls are windows and too many is very expensive).
So, extend the ProgressBar class and draw the text in the middle like so (just a basic example):
public class ProgressWithText : ProgressBar
{
Brush textBrush;
public ProgressWithText()
{
SetStyle(ControlStyles.UserPaint, true);
textBrush = new SolidBrush(ForeColor);
}
protected override void OnPaint(PaintEventArgs e)
{
base.OnPaint(e);
e.Graphics.DrawString(Value.ToString() + "%", Font, textBrush,
(RectangleF)Bounds);
}
protected override void OnForeColorChanged(EventArgs e)
{
base.OnForeColorChanged(e);
if (textBrush != null)
textBrush.Dispose();
textBrush = new SolidBrush(ForeColor);
}
}If you want to change the color of part of the text when the actual progress bar moves under the text, you should consider painting the whole thing (easier in the long run), which isn't too hard. Search for "progress bar" on this site for a number of good articles about owner-drawn progress bars.

Thanks, however when I go to compile this code, the compiler tells me that I can't inherit from ProgressBar because the class is sealed.
|
|
|
|
|
Hmm...so it is. I must apologize. I've never had a reason to extend it and other controls are sealed that I have extended. Progress bars are very easy to create. Please follow my suggestion to search this site for "progress bar" and you'll find lots of articles how, including progress bars with gradients, custom pictures, and more; some even provide sample code that shows how to draw the percentage text (similar to how I did it above).
