Erhm, it looks like you're converting 1 to the declared integer 'status'... This makes everyone an admin :->

Hi,

How many records has your database and how do you know you have the proper row?

I would do it something like this:

<br />
String connection = "uid=sa; password=sa123; database=usermanagement; server=c113";<br />
<br />
SqlConnection con= new SqlConnection (connection);<br />
SqlCommand cmd=new SqlCommand ("select * from tbl_user_management where username ='" + txtUsername.Text + "'",con); // where clause ?<br />
                        <br />
SqlDataReader dr;<br />
//don't forget the try catch finally !<br />
con.Open ();<br />
dr=cmd.ExecuteReader ();<br />
<br />
if (dr.HasRows())<br />
	{<br />
	if (dr.Read())<br />
		{<br />
			// Don't understand these lines<br />
			Lbluser.Text = String.Empty;<br />
		        Lblpassword.Text =String.Empty;<br />
		        Txtusername.Text ="username";<br />
		        Txtpassword.Text ="password";  <br />
			// end Don't understand          <br />
		            int status = Convert.ToInt32(dr["status"].ToString());<br />
		}<br />
	}<br />
con.Close();<br />
switch (status)<br />
{<br />
	case 1: Response .Redirect ("admin.aspx"); break;<br />
	case 2: Response .Redirect ("Welcome.aspx"); break<br />
	default: break; // you could do something with a Error routine<br />
}<br />
<br />

Hi,

How do you run an application under different credentials?

I have created a small app which accesses active directory. One of its tasks is to move objects. However only admin credentials can move object as i wish to. I need to run my c# windows app under this username and password so that i can move these objects.

Thanks

PLease don't repost the question just because you didn't get the answer you are looking for.

The problem is that you cannot access a GUI object (like the listbox) from a different thread, other than the main application thread. You have to do an invoke back to the GUI thread for that. But if the binding itself is time-consuming, the Invoke will not help because you are again doing it on the GUI thread so your application will not respond during that period.

If you can isolate the time-consuming bit of the code, you can move that alone to a different thread and then Invoke back to the GUI thread when you are done.

How to pass a Control to a Method

Hi,

I have a small problem.
In a gridview I want to read out cellValues. It regards the reading of cellValues after Editing.
My Method

<br />
public string giveCellValue(Object typeOfObject, GridView gv, Int32 rowNumber, Int32 cellNumber, Int32 controlNumber)<br />
{<br />
return ((typeOfObject)gv.Rows[rowNumber].Cells[cellNumber].Controls[controlNumber]).Text;<br />
}<br />

If I want to read out a textBox object I want to do:
String ReadValue = giveCellValue(TextBox, gridMyGrid, 1, 0, 0);
For a Label I want to do
String ReadValue = giveCellValue(Label, gridMyGrid, 1, 0, 0);

That is where .NET shoots me and says I cannot pass the object as a variable.
How to overcome this problem.

Hi,

if you define giveCellValue(TextBox myTextBox, ...) then it will accept any TextBox,
but it wont accept a Label.

if you define giveCellValue(Control myControl, ...) then it will accept a TextBox,
a Label, and all other Controls; now you can access myControl.Text since Text is a
property that exists for all Controls; but you still would not be able to access
a property that exists just for some Controls.

The better way however is to define giveCellValue(string text, ...)
and call it like so:
String ReadValue1 = giveCellValue(myTextBox.Text, gridMyGrid, 1, 0, 0);
String ReadValue2 = giveCellValue(myLabel.Text, gridMyGrid, 1, 0, 0);

Doing so giveCellValue does not have to touch other, independent, Controls at all.
It is better from OO perspective.

Hope this helps.

entry point of OLE DB Provider

George_George19-Jul-07 0:18

19-Jul-07 0:18

Hello everyone,

I am implementing a simple C# OLE DB Provider (C# COM Server). For C# (managed code), I am wondering what is the entry point (which coclass and which method), client will invoke at first?

It is clear if I write my own client, but I am confused about other clients which I do not have source codes, for example, if I use Microsoft Excel (as a client) to invoke my C# OLE DB Provider, which is the entry point? Any reference materials or debug tools?

thanks in advance,
George

ArraySorting:

I have to Sort An Array using C#. I have declared the Array to be 50 element size. I have got the array elements from the user using for loop. If I print the original array, the elements I entered got printed very well. I
have used the Array.Sort(arrayname) function in the Array Class to sort the elements.
After sorting, I printed the elements. All the elements got printed as Zero. Can any one tell What may be the problem?

The code is:

static void Main(string[] args)
{
//
// TODO: Add code to start application here
//
int num_ele;
int[] num = new int[50];
Console.WriteLine("Enter the Num of elements in the Array");
num_ele = Convert.ToInt32(Console.ReadLine());
for(int i = 0; i

Hi,

that is how it looks if you test it with:
- no more thsn 25 numbers, all positive
- more than 25 numbers, all positive, of which several are zero

try it again with negative numbers !

The problem is you have a fixed array size of 50; if you enter fewer numbers, Array.Sort
will still sort those 50 numbers (the ones you did not enter all are zero).

Now listing the sorted array will include the extra zero elements, and if they happen to
be the smaller numbers, they come out first.

Furthermore your program will fail if the user asks for more than 50 numbers.
When entering the 51th number you will get an IndexOutOfRangeException.

This is how you can fix both problems:
- dont use an array, use another kind of collection (such as ArrayList, or List<int> )
- these classes automatically adapt themselves to the number of elements
- and they provide the same Sort facility

May I suggest you read a chapter on collections, then try to use them to your
advantage.

in the declaration, you (implicitely) initialised the array with 50 zeroes, Now, for instance, if the user inputs ten positive numbers, then the Sort method will move the reamaining 40 zeroes into the leading positions of the array, putting the user's entries in the last 10 ones (if you output the whole array then you see the mistake).

Hi,

I forgot to mention there is another overload of Sort() that accepts boundary information,
so that can solve your immediate problem; it still leaves you with the 50 limit:

public static void Sort (
Array array,
int index,
int length
)

in your case that would be: Array.Sort(num, 0, num_ele);

For general information on either .NET or C# I would recommend you buy at least one
book and work your way through it. You could also read what MSDN has to say about
ArrayList class for instance.

How do I add a base interface using ModuleBuilder.DefineType()

fpdeguzma7818-Jul-07 23:55

fpdeguzma78

18-Jul-07 23:55

I am using System.Reflection.Emit to create a dynamic assembly. I use ModuleBuilder.DefineType() to add a class type. I want to add a base interface e.g. "ICalculator" to my class definition but unfortunately i cannot figure out how to do this dynamically. The class constructor doesn't have any parameters. The "Interfaces" namespace has the "ICalculator" interface.

The class generated should be like this:

using Interfaces;

namespace ConcreteLibrary
{
public class ConcreteCalculator : ICalculator
{
public ConcreteCalculator()
{
}

#region ICalculator Members

public object Calculate()
{
// do nothing;
return null;
}

#endregion

}
}

How do I include the "Interfaces" namespace and the "ICalculator" interface to the "ConcreteCalculator" class? Your help would be very much appreciated.

Thank you in advance! Smile | :)

Haven't worked with MS Text Driver or any csv data but first thing that comes to mind is:

Make sure Regional settings are compatible with your .txt files. Maybe your list separator is not the same in both OS.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
