The synchronization app is exactly the kind of app that should be implemented as a windows service even without the UAC prompting issues.
UAC has imposed some architecture changes, configuration files should be place in “Application Settings” directories or isolated storage which are accessible without elevation. Similarly plug-ins can be placed and loaded from those 2 locations. A self updating app could be achieved be installing a basic exe to program files and then loading the bulk of the app code into app settings so it can be replaced if needed or UAC elevation for this feature is completely understandable and the standard practice (Firefox, OpenOffice, etc) all prompt for elevation when updating.

I have t1,t2,t3, 3 threads, and 1 AutoResetEvent(ar),
Is ar able to synchronize the three threads?
|
|
|
|
|
what do you mean by "synchronize three threads"? could be many things, such as: have the starting thread wait for all of them to finish; have all of them to wait for a common event; etc.
Whatever it is, the answer is: yes. The way to get it done will be different however.

i think synchronizing itself has a lot of meaning... like is all 3 threads running together? or is it waiting for autoresetevent set method, and which thread is waiting for which thread? at foldersync i recently create, i use 3 autoresetevent to control 3 threads.... L

Hi,
When i type any value in a cell of a DataGridView a new row is added automatically in the DataGridView, but if i select any value from a combobox, in some case a new row is generated, but not in some cases.
I need to generate a blank row when i click on any cell of the last row.
Thankyou
YPKI

What you are running across is the limitation and inconsistency of editing in a list control (DGV). Most developers will not supply inline editing unless it is for a trivial set of data (1 cell only).
What I suggest you do is pop a dialog when the user double clicks (for edit) or clicks an add button. In the dialog you have complete control of the data. When the user has completed editing and closes the form then reload the list control and select the edited item.
Never underestimate the power of human stupidity

hi! everyone!!
I am using Windows application. I want to get single,single value from listview(contains two column) when I click a row.
my 1st column name is 'code'and value is '123' and second column name 'desc' value 'good'
If i click its return value but gives this type of value:
listview1:{123}
code sample:
private void listView1_Click(object sender, EventArgs e)
{
ListViewItem value1 = (ListViewItem)listView1.Items[0];
string val =Convert.ToString(value1);
}
please guide me,
thanx and regards

Phil pointed you to another ListView property: SubItems, which is indexable.
Did you read up on it? did you perform a little experiment?
BTW: when you know a column isn't text (say a number), and you want its value, then don't use Convert or ToString(), just cast!
|
|

|

hey you can use given code to get value based on row on which you click.
string txt = listView1.Items[listView1.FocusedItem.Index].SubItems[0].Text;
if you need value of both second column you have to change value of SubItems to column index as
string txt1 = listView1.Items[listView1.FocusedItem.Index].SubItems[0].Text;
string txt2 = listView1.Items[listView1.FocusedItem.Index].SubItems[1].Text;
you can also use loop with SubItems for getting value..

There is a similar thing i have written for Web.
Group GridView Data[^]
Please check if it could help you. (But it support only 1 level of grouping at a time.)

Google for a drill-down grid. I doubt that there'll be a free version that can be used (with a consistent look) in both web & forms though.

If you're going to use it in web apps, then, try jqGrid for asp.net.

Here is the obvious way (just an example):
byte[] arrARGBValues = { 255, 255, 0, 0, 255, 255, 0, 0, 255, 150, 255, 255 };
int lengthARGBValues = arrARGBValues.Length;
int lengthSubArrays = lengthARGBValues / 4;
byte[] arrAValues = new byte[lengthSubArrays];
byte[] arrRValues = new byte[lengthSubArrays];
byte[] arrGValues = new byte[lengthSubArrays];
byte[] arrBValues = new byte[lengthSubArrays];
for (int i = 0, j = 0; j < lengthSubArrays; i += 4, j++)
{
arrAValues[j] = arrARGBValues[i];
arrRValues[j] = arrARGBValues[i + 1];
arrGValues[j] = arrARGBValues[i + 2];
arrBValues[j] = arrARGBValues[i + 3];
}

when you have an array (or any other collection) of colors, you can manipulate them directly. There is no need to first display them (i.e. their string representation) in a ListBox and then parse those strings, that approach is so wrong.
Here is an example of what one can do, without ListBox, without parsing text:
Color[] colors=new Color[3];
colors[0]=Color.Yellow;
colors[1]=Color.Red;
colors[2]=myImage.GetPixel(0,0);
or
List<Color> colors=new List<Color>();
colors.Add(Color.Yellow);
colors.Add(Color.Red);
colors.Add(myImage.GetPixel(0,0));
...
then
int sumRed=0;
int count=0;
foreach (Color color in colors) {
sumRed+=color.R;
count++;
}
int averageRed=sumRed/count;
see? no ListBox, no strings, no problems. Also less code, and much faster.

oh because my array consist of many entries made up of A, R, G, B. i dont think i can make use of your methods as listed above.

and that is completely silly, why would you mix up things that you later on need separately?
