Re: How to access data from a control on one from from another form?

First the info you've provided isn't suffecient to judge the problem, but I'll take few guesses here.
1- The way you use to copy the array -ignoring the MessageBox of course- is quite wrong. You should use Array.Copy() or Array.CopyTo() static methods instead.
2- Failure of the static array ecludes that discarding the values of the CheckedIndices when closing the form is the problem.
3- Make a breakpoint and see the values of:
a. count
b. CheckedIndices.Count
c. indice.Count

Waiting for your reply.

well nader

the way i'm copying indices like this is due to the requirement of my problem.
the code i mentioned above is actually a function of form A. when i access this function from Form A, it works fine. But as soon i call the function from Form B it gives the exception. the complete function is:

public int[] GetCheckedIndices()<br />
	{<br />
	int count=Global.Instance.Count_Indices;<br />
	indice = new int[count]; <br />
	MessageBox.Show(count.ToString());<br />
	for(int i=0;i<count;i++)<br />
	{<br />
	indice[i] = TableListBox.CheckedIndices[i];<br />
	MessageBox.Show(indice[i].ToString());<br />
	}<br />
	return indice;<br />
	}//end function

now TableListBoxis the name of me checkedListBox
and CheckedIndices is its property.
indice has been declared as "public static int[] indice".

CheckedIndices.Count has the index of the items that have been checked in the chckedListBox.
ope this gives u enough information to understand the problem

awaiting you reply.

Things are starting to clear up a bit, but don't be frustrated when I tell you that you still didn't answer all of my questions. I'll put them straight this time:
1- Do you call GetCheckedIndices() from FormB directly? please post the code in FormB.
2- What is Global.Instance.Count_Indices?
3- When the above method is called by FormA. What are the numerical values of:
count, indice, TableListBox.CheckedIndices
4- Again when you call the same method from FormB; What are the respective values?

Forgive me if I didn't get a clear idea, or if I'm asking too much misleading question, but I'm trying to cover all the possibilities here.
Waiting for your reply. I hope that my next reply would be the answer.

There is nothing built in to .NET that I'm aware of. The closest you'll get is say: 1 November 2006. You would have to create a custom class to handle this.

Try using the DirectX 9 SDK. Examples are included. But if you're a novice at C# then I suggest you learn the basics first, since directx isn't so simple to begin with...

Well, if you have some expercience already, I assume you already know about gdi. I'd use that to display the image. If you need a way to go fullscreen, just google. There's plenty of examples. Also, there's a p/invoke thingie for playing sound. If you insist on using directX, I don't see why you would, just use the examples that come with the sdk.

You can have a MSI project to setup right. That would manage your install and deinstall seamlessly. To create a MSI project you can access New -> Project -> Setup and Deployment project in your Visual Studio.

Holding the form untill all controls are painted

Hi all,

I have an application that fetches data from a web service, and then displays the data into the datagrid on a form.
I have put some images so that the form looks similar to the Web page developed for the same application.

Now the problem is when i show the form the form displays and then all the controls are slowly painted on it.

What i want is the form should not be displayed until all the controls are fully painted on the form. So that it does not flickers.

Any ideas, pointers in this regard will be appreciated.

Thanks & Regards,
Pramod

Capturing RightClick on DataGrdiView

Hi every 1,
I have a project in which I am using DataGridView and I have to show ContextMenu on the grid.
The problem I am facing is, I need either the Index of the cell where the user "Right Clicks" or get it selected some how... The reason I can't do it is that the when I assign context menu to the DataGridView it takes over the RightClick event of the DataGridView meaning that it will never be fired.

If any1 can suggest a feasible solution to it I will be great full.

iterating through tabpages in a tabcontrol

Hi,

I'm trying to check if a certain tabpage is selected.

This is how i tried it:

foreach (TabPage tabControl in this.tabControl1)
{
if (this.tbp1)
{

}
}

I didn't find any property which represents "selected" for this.tbp1.

And i also got an error in the foreach statement which says:

foreach statement cannot operate on variables of type 'System.Windows.Forms.TabControl' because 'System.Windows.Forms.TabControl' does not contain a public definition for 'GetEnumerator'

How can i iterate through my tabpages in a tabControl and check if a certain tabpage is selected or active?

Thanks in advance!

Hello,

You have to compare the Index property of the TabPage, and the SelectedIndex property of the TabControl.

foreach (TabPage tp in this.tabControl1.TabPages)
{
    if(tp.Index == this.SelectedIndex)
    {
        //tp is the Selected TabPage
    }
}

Hope that helps!

All the best,

Martin
