Could you clearify the question? I don't really understand what you want to do, and certainly not how it has anything at all to do with pointers.

Am I smelling Database in here? If you want to manipulate data go for SQL, and yes you can do that in C#.

What are the errors you get exactly? Also a code snippet would be very helpful.

DriveInfo[] drivesInfo = DriveInfo.GetDrives();
foreach (DriveInfo drive in drivesInfo)
listBox1.Items.Add(drive.Name + " " + drive.VolumeLabel);

I would put the listBox1.Items.Add... in a try/catch , because you probably are asking your DVD-drive to tell you the VolumeLabel and if there is no DVD in it you will get an exception.

Hello Everyone
I was trying to write the algorithm that finds the anagram of words randomaly
for example hello
so far this is what i have
public void findAnagram(String prefix, String suffix)
{
String newPrefix, newSuffix;
if (suffix.Length == 1)
{
Console.WriteLine(prefix + suffix);
}
else
{
for (int i = 0; i < suffix.Length; i++)
{
newSuffix = suffix.Substring(1, suffix.Length);
newPrefix = prefix + suffix[0];
findAnagram(newPrefix, newSuffix);
suffix = newSuffix + suffix[0];
}
}
}
but for some reason it throws me a exception when i put it in main method
"Index and length must refer to a location within the string."
i am wondering if there is a better way to find a anagram of any word
thank you

As you're starting at 1, and it's 0 indexed, the Length property goes one character past the end.

Row associated with the currency manager's position cannot be made invisible
How to solve problem and hide each Row that i select at runtime without this error ?
My Code is :
int i = 0;
while (i < this.dataGridView1.Rows.Count)
{
DataGridViewRow GridViewrow = this.dataGridView1.Rows[i];
if (GridViewrow.Cells[0].ToString() == "True")
{
}
else
GridViewrow.Visible = false; //error in this line
i++;
}

Well I'm not totally sure, but I can tell you're having a BindingSource problem.
In my expirience, I wouldn't be able to edit almost nothing usingn BingdingSource or TableAdapters, because we can not mess with the internal managment of the .NetFramework.
Solution: Fill the DataGridView manually using sql querry, it should solve the problem.. (I mean manually exactly how it sounds.. row by row and Cell by Cell)
good luck.
(sorry my english)

After taking a break from Microsoft IDE's and working in Java land, I'm missing the Control-LeftClick to click through a definition to navigate to the definition.
In Visual C# 2005 this just feels too clunky requiring a right-click and selection of a menu item.
I don't suppose anyone knows an option/plug-in that performs this?
Regards,
Ray

In my VS 2003 it's currently mapped to F12. But you can define an alternative key combination in Tools->Options->Keyboard and then slect Edit.GoToDefinition and type in a desired key combination. In VS 2005 it will be similar.

That is also mapped to F12. You could change the mapping if you prefer.

hi
i add an Unbound DataGridViewCheckBoxColumn to my datagridView for user to select each record that he wants to print (print with DataGridViewPrinter Class), I want to invisible other records that checkbox is False or null,
but at RunTime when i set a checkbox to true and uncheck it again (set to false)
when i want to invisible that record .. the following error shown me :
Row associated with the currency manager's position cannot be made invisible
my code is :
foreach (DataGridViewRow _gridViewRow in dataGridView1.Rows)
{
if (_gridViewRow.Cells[0].Value != null)
{
if (_gridViewRow.Cells[0].Value.ToString() == "True")
{
_gridViewRow.Visible = true;
}
else if (_gridViewRow.Cells[0].Value.ToString() == "False")
{
_gridViewRow.Cells[0].Value = null;
ds_zamin1.Khaneh_1.Rows.RemoveAt(_gridViewRow.Index);
}
}
else
{
_gridViewRow.DataGridView.EndEdit();
_gridViewRow.Visible = false; //Error Occured In this Line
}
}

You cannot make selected row/cell inviible.
Use...
dataGridView1.CurrentCell = null;
|
|
|
|
|
Try this.
CurrencyManager cm = CurrencyManager)BindingContext[this.DataGridView1.DataSource];
cm.SuspendBinding();
this.DataGridView1.Rows[index].Visible = false;
cm.ResumeBinding();
