I digged out further and imagined that the problem i described, it will no longer be the issue at all. Can you please answer or help out the problem that I described. Because the problem now directed as this.
"How can Remoting Obj Uri be gernated at runtime at subscriber's end?"

Hello,
I have to work on one application that uses WCF web service. I know how to consume ASP.Net web service. May I know how consuming WCF web service different than ASP.Net service. Please, I want details for client only. Is it make any difference for proxy class.
Thanks in advance.

It is more or less similar if you are just calling the service operation without playing around with the requests or something else. Instead of adding web reference, add service reference. Or use svcutil to create the proxy class.

I have a function that loads data and configures the datagrid. I did this so that all the datagrids in the project would be the same. So I added a bit of code that is supposed to add row numbers to each of the datagrids.
<pre>
int numberofrows = DG.Rows.Count;
int len = numberofrows.ToString().Length;
string NumberForRow;
for (x = 0; x < DG.Rows.Count; x++)
{
NumberForRow = Convert.ToString(x + 1);
while (NumberForRow.Length < len)
{
NumberForRow = "0" + NumberForRow;
}
DG.Rows[x].HeaderCell.Value = NumberForRow;
}
</pre>
This code is fired as so
GF.LoadDataGrid(dgInvoices, DT, true,"InvoiceID,OrderID,Status,Date", "EVEN", "");
Where GF is GeneralFunctions class and LoadDataGrid is a method, the paramaters are dgInvoice is the DataGridView to load, DT is the DataTable, true/false is readonly, The first string is the Column headers, the second string is column spacing and the last string is columns that need to hidden if any. No the weird part. This line of code does not put in the Rowheader numbers. The DataGridView dgInvoices has an event tied to it that fills in another datagrid view with the detail of the invoice the call to fill that DataGridView is exactly the same
GF.LoadDataGrid(dgInvoiceDetail,DT,true,"ItemID,Description,Qty,Amount","EVEN","");
and for that datagrid the number do appear. I know that there is no difference between the two datagrids as on the form, I have copied and pasted the first datagrid to make the second datagrid so they are the same. Not sure what is going on.
Any help would be appreicated.
Thank you.

What length are you trying to get? this does not seem right. It looks you are trying to figure out how may digits are in a number. Is that right?
int len = numberofrows.ToString().Length;
int NumberForRow = 1;
foreach (DataGridViewRow row in DG.Rows)
{
if(NumberForRow < 10)
row.HeaderCell.Value = String.Format("{0:D2}", NumberForRow );
else
row.HeaderCell.Value = NumberForRow;
NumberForRow = NumberForRow+ 1;
}

True I am trying to find out how many digits are in the number so I can make the row headers all the same length. So if there are 1-9 rows the headers would look like 1,2,3,etc... and when there are 10-99 rows then 01,02...99, and 100-999 then 001,002,003...999 and this part works fine. The problem is that the row numbers don't show up at all in the first datagrid and they show up just fine in the second datagrid, using the exact same code.

For positive numbers this will do:
row.HeaderCell.Value = NumberForRow.ToString().PadLeft(requiredWidth, '0');

An update to the problem. I took the code above and made a separte function out of it. Then Added the call to it after the GF.LoadDataGrid call with the same result. No numbers. Then I added a button to the form that called the same function. After the page was rendered and I clicked said button and the numbers appeared. So it seems that for some reason after the numbers are put there and the grid is rendered the row numbers disappear. Not sure why?

Something like this won't do? (The DataGRidView has an unbound column added at column 0 for the index)
private void dataGridView1_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
{
foreach (DataGridViewRow R in dataGridView1.Rows)
{
R.Cells[0].Value = R.Index;
}
}
EDIT: Oops. Never mind. Just noticed you want to put it in the row header cell....which doesn't work in the above code.

Hey ,
I have this task but I don't know what I should do , Please help me.
task :
-------------
An integer that is greater than zero is said to be n-factored if it has n distinct factors other than 1 and itself. For example 12 is 4-factored because its factors are 2, 3, 4, 6. A prime number is 0-factored.
Write a function named isNFactored that takes two arguments, an integer and some value of n, and returns 1 if the integer is n-factored. The function signature is
int isNFactored(int value, int n)
|
|
|
|
|
if value n return reason
14 2 1 14 has two factors, 2 and 7
18 5 0 18 does not have 5 factors, it only has four (2, 3, 6 and 9)
25 2 0 25 = 5*5 but we are only interested in distinct factors so the 5 is only counted once.
36 7 1 36 has seven factors (2, 3, 4, 6, 9, 12, 18). Note that 6 is counted only once.
7 0 1 all prime numbers are 0-factored
-5 anything 0 the value must be greated than 0
and I do code know but I doesn't know what is meant by return type?
public static int GetFactorCount(int numberToCheck, int n)
{
int factorCount = 0;
int sqrt = n;
for (int i = 1; i < sqrt; i++)
{
if (numberToCheck % i == 0)
{
factorCount += 2;
}
}
if (sqrt * sqrt == numberToCheck)
{
factorCount++;
}
return factorCount;
}

It is really easy to count the number of prime factors of a number. I will not give you the implementation, but can help you with the algorithm.
1. Define a factorCount variable and initialize it to 0.
2. Define a factor variable and initialize it to 2.
3. If factor is equal or bigger than the number to check, goto step 6, else, continue by step 4.
4. If factor divides the number to check:
4.1 Increase factorCount by 1.
4.2 Divide the number to check by factor.
4.3 Go to step 4.
5. Increase factor by 1.
5. Go to step 3.
6. Return factorCount.
That is all.

You probably need to start by researching any algorithms that solve the mathematics of this question. Once you know that solution it should be a simple matter to convert it into the programming language of your choice.
Is this really a .NET question?
I must get a clever new signature for 2011.

Try something and post the code here (if you face any issues).
Someone will try and help you.
The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it.
My latest tip/trick
|

Since the function signature is quite misleading from a C# point of view, let me give you some hints:
the return value is actually a boolean: "returns 1 if the integer is n-factored", and implicitly 0 otherwise - that's a stone-age coding praxis typical of C or COM. Now you can start to interpret the parameters: "value" should be the integer number for which to find the number of factors, and "n" the number of factors. I.e. if "value" has "n" factors return 1, otherwise 0.
Now take the code you've posted, and make little changes: calculate "sqrt", then compare "factorcount" and "n" for getting the return value.

I have a CustomerInfo form which is an Mdi form to the main form. The CustomerInfo form a has TabControl with 4 TabPages on it.
From the Main form
CustomerInfo CI = new CustomerInfo();
In the form constructor event i have the following pseudeocode
LoadGeneralTab()
LoadOrderTab()
LoadInvoiceTab()
LoadPayHistoryTab()
Each of these functions loads several Datagrids with information.
Then from the main form
CI.MdiParent = this;
CI.Show();
The CustomerInfo form shows up as expected and all is good. But when I click on the orderTab or invoiceTab or the payHistoryTab it takes a long time to switch over to it. And the speed of the switch seems to be the amount of information contained in the datagrid views. What I don't understand is why this is happening as it seems to me that all the grids have been populated with information in the constructor so what is taking so long to switch over. I have done this before and not had the same problem. And help would be appreciated.

Doesn't that answer your question. That implies you need to look closer to how the data is retrieved. May be you need to optimize your query. It is kinda hard to tell without looking at the code.
|
|
|
|

No not really, It does take some time for the CustomerInfo form to show up, and I assume that is because it does take time to load all the information on each of the tabs. But once the CustomerInfo form is displayed all the information should be loaded. So switching between tab pages should be quick. But it seems that the tabs are being reloaded everytime I switch over to them.

I guess the Controls (DGVs) that haven't been visible yet (those not on the first tab page) still haven't been rendered at all; so clicking on a tab will first cause the DGV to be actually created (including its Handle property), then the data being loaded into it.
You could force this to happen sooner, IIRC reading Control.Handle suffices to make sure it really exists. Of course adding this to your Form.Load (or Shown) event will postpone its rendering of everything, including the first tab.
A better way to handle the situation could be this, and I would recommend it anyway whenever the database accesses might take more than a second:
- launch a thread to access the database, do not touch the Controls from that thread;
- in the mean time, make sure all Controls really exist (Handle!);
- when the database thread is done, make it signal the GUI thread and start showing the data.
A BackgroundWorker would be good, having the DB stuff in its DoWork and the show-in-GUI stuff in its RunWorkercompleted handler.

It's the grids doing it, not the database access as such.
If you can "page" the results for the grids, only loading as many rows as will be displayed, it should speed up a bit.

I'm writing a program that uses net framework 4. another person will use this program in his own computer. Is it necessary for he/she to have net framework 4 installed in his/her computer? which version he/she will require?
Thanks,

If you build it to run on .Net 4, the target machine will need to have .Net 4 installed.
Will Rogers never met me.

They will need .NET installed on there machine. Framework 4.0 will be required. It must also be a Windows operating system and in fact if it is Windows 7, it should have it already installed.
Best to create a installation for your app that will handle the dependency for .NET. Test the installation before releasing.
It shouldn't be a big deal.
