I have an application that queries records from a Visual FoxPro 8.0 table. I created an install project for this application an included the Vfpoledb merge module. When running the installed application on the development computer everything works fine. But when I install it on a Vista computer and try running it comes back with the error 'Cannot register Vfpoledb.1'. I'm installing it under the admin account. Any ideas on how to fix this problem? Thanks.

If you mean the exe that is your application then you can't.
If you're moving an exe file within your application, then you can use the System.Diagnostics.Process class and it's Start method to start the exe.

Your can use your code to start it:
System.Diagnostics.Process.Start(anotherlocation+filename);

Create a Control and do your own drawing instead of using 168 labels!
If you've never created one before it's pretty easy. The code below will simply draw the control's Text at it's point 0, 0 using it's ForeColor and Font properties - and sets the default size for the control to 100, 100.
You can use this as a base to get started.
using System.Drawing;
using System.Windows.Forms;
public class ClockGrid : Control
{
public ClockGrid()
{
Size = new Size(100, 100);
}
protected override void OnPaint(PaintEventArgs e)
{
Point textPoint = new Point(0,0);
using (Brush brush = new SolidBrush(ForeColor))
{
e.Graphics.DrawString(Text, Font, brush, textPoint);
}
base.OnPaint(e);
}
}

Wouldn't it do displaying a Digital clock with time like 08:02:10 ?? You could easily show date too (08:02:10 08-March-2009)

TRy not to use so many controls since they consume a lot of resources.
To test the true performance use Release mode and not DEBUG mode.
There are plenty of articles discussing custom controls and overriding OnPaint.
Here is a small sample:
///
/// A custom control
///
public class MyUserControl : UserControl
{
#region Constructors and Initializers
///
/// Initializes the <c>ChartControl.
///
public MyUserControl()
{
SetStyle(ControlStyles.UserPaint, true);
SetStyle(ControlStyles.AllPaintingInWmPaint, true);
SetStyle(ControlStyles.DoubleBuffer, true);
SetStyle(ControlStyles.ResizeRedraw, true);
SetStyle(ControlStyles.Opaque, true);
UpdateStyles();
InitializeComponent();
}
#region Event Overrides
protected override void OnPaintBackground(System.Windows.Forms.PaintEventArgs pevent)
{
//Do Nothing
}
protected override void OnPaint(PaintEventArgs args)
{
//Paint logic (first call graphics.Clear(BackgoundColor)
// Start drawing
}
#endregion
}

Hello Friends,
How can i change the size of an Array at runtime in C#.Net.
In VB.Net, i can do it using "ReDim" & "Preserve" keywords.
Is there anything similar in C#.Net, so we can change the size at runtime?
Thanks and Regards,
Nagendra.

Can we use MultiDimensional ArrayList?
|
|
|
|
|
I hope multidimensional arraylist can be done by, Each element of the ArrayList would then be another ArrayList.
ArrayList a = new ArrayList();
a.Add(new ArrayList());
|
|

|

ok thanks, i'll try this.

Hi,
In all .NET languages one-dimensional arrays can be resized, see the Array.Resize() method in the documentation. "This method allocates a new array with the specified size, copies elements from the old array to the new one, and then replaces the old array with the new one."
When you need to resize an array several times, or if you just don't know what size to choose at the start, you are probably better off choosing another kind of collection. The old ArrayList still exists, but it is better to use a generic list (that's List<T> ) which provides type checking and better performance. These collections grow and shrink dynamically without copying their content [ADDED] all the time (in the current implementation they grow by rounding up their capacity to the next power of 2 and copying only then).[/ADDED]

Actually List<t> does copy all its elements when it needs to grow.
Go to System.Collections.Generic.List<t>.set_Capacity(int value) in for example Red Gate's .NET Reflector..

Right. I keep forgetting that. Back to the home-made linked lists then.

i am developing a windows mobile C# application, how to save application settings? The user should be able to update these settings, but the settings want to be retrieved next time application starts. Do i need to use registry key? or xml config? any other good way to achevie this??
|

Try and save the data to a path such as:
Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
You can serialize your data in xml/binary format.
I prefer not to write to the registry, that is dirty.

the article does not change the date setting as control panel.the article only changes date format to string in run time. what i want is to change the date format as i am changing from control panel.
this means i want to change computer date format from c# application and it should affect control panel too.
