Nope, didn't understand a thing!
Sorry, but I understand each word, but put together like that I didn't understand any of the sentences...

I have never used devcomponents but I assume they are the same as anything else - if you need to run a procedure that is going to take more than a few milliseconds you should launch a thread (look at the BackgroundWorker possibly) to do it on so the UI's thread doesn't lock.

nice solution , but is this problem is regular in automation programs ?
i mean get really slow/slow when the size of the data get increased ?
|
|
|
|

Not necessarily but it depends on how you code the data access stuff. Poor code, poor data validation etc or caching/displaying a lot of data is always going to be slow. Good code and only caching/displaying a sensible amount of data at once will be fast - all other things being equal.

Hello guys. I am copying one ArrayList into another ArrayList. However, I am calling ToArray() on my source ArrayList. Later when I try to retrieve values from my target ArrayList, it only gives my System.String[], instead of string values. Here is what I am trying
public void CopySetting(ArrayList mySrcArrayList)
{
myTargetArrayList.Clear();
myTargetArrayList.Add(mySrcArrayList.ToArray(typeof(string)));
}
public GetValues()
{
foreach (Object obj in myTargetArrayList)
{
string str = (string)obj.ToString();
}
}
So what could be wrong here? Thanks for any help.

ahhh. It is Target ArrayList. I think I could not modify my original code properly.

that's the main problem when you work with ArrayList, Add method simply accepts any object you pass. here you are adding the string[] returned by the source.ToArray operation. to Add the array range you should use array.AddRange.
My personal recommendation is to avoid using ArrayList in your application and use Generic lists.
public void CopySetting(ArrayList mySrcArrayList)
{
myTargetArrayList.Clear();
myTargetArrayList.AddRange(mySrcArrayList.ToArray(typeof(string)));
}

Yeah don't use ArrayList unless there is some good reason you don't want type safety. Even if the initial list is a heterogenous one in this case, so you want an untyped list, you should definitely be using List<String> as the target, since you're only adding strings to it.

Hello everyone i'm a biginner of c# programming someone can help me to improve my skills. I need sample project to exercise my learning. thank you

The first place you should try when stuck on something is MSDN. C# Sample Applications[^] is a good p[lace to start.

You can learn by reading a few books on C#.
There will be a number of samples that you could try from these books.

I have created a windows form chart and it is very small the only way I can change its size is by stretching the chart but it is only a percentage of the charts container size, I have spent forever going through the properties and I cannot see what is affecting it, here is an image of it:
http://deucalion0.co.uk/chart.PNG[^]
You can see the white are is the size of the chart but it is nowhere near the same size, can anyone tell me why?
Thank you!!

Without knowing what you're using for a chart control or if you made your own, it's pretty much impossible to help you.

I apologise for the lack of information in my question!
I am using this:
using System.Windows.Forms.DataVisualization.Charting;
The code for my chart properties in the designer file is as follows:
chartArea1.Name = "ChartArea1";
this.chart1.ChartAreas.Add(chartArea1);
legend1.Name = "Legend1";
this.chart1.Legends.Add(legend1);
this.chart1.Location = new System.Drawing.Point(0, 0);
this.chart1.Name = "chart1";
series1.ChartArea = "ChartArea1";
series1.Legend = "Legend1";
series1.Name = "Plots";
series2.ChartArea = "ChartArea1";
series2.Legend = "Legend1";
series2.Name = "Regression Line";
this.chart1.Series.Add(series1);
this.chart1.Series.Add(series2);
this.chart1.Size = new System.Drawing.Size(1212, 771);
this.chart1.TabIndex = 13;
this.chart1.Text = "chart1";
this.chart1.Click += new System.EventHandler(this.chart1_Click);
I am new to this kind of project So forgive me if there is still something missing.
Thank you!

The code isn't here, but you may have set the size of the ChartArea1 in the designer to be a fixed size instead of Auto.
I preffer to remove all of the default collection items that dropping the chart object on the form adds, including all Legends, ChartAreas, Series, Annotations, ... and just create everything in code and add them to the appropriate collectiosn manually instead of modifying what's there. I did this without any problems:
Dim chartArea As New ChartArea("TestChartArea1")
chartArea.AlignmentOrientation = AreaAlignmentOrientations.All
chartArea.AlignmentStyle = AreaAlignmentStyles.All
Chart1.ChartAreas.Add(chartArea)
Dim legendArea As New Legend("TestLegend1")
Chart1.Legends.Add(legendArea)
Dim series As New Series("Series1")
series.ChartArea = "TestChartArea1"
series.ChartType = DataVisualization.Charting.SeriesChartType.Line
series.XValueType = DataVisualization.Charting.ChartValueType.Int32
series.YValueType = DataVisualization.Charting.ChartValueType.Int32
For Each p In New Integer() {1, 2, 3, 4}
series.Points.AddXY(p, p)
Next
Chart1.Series.Add(series)
