Hi.
I have created a class that read data from the database and i want to display this data on labels.
here is my class
public void SeachProduct(string PBarcode,string PName,string PPrice)
{
Barcode = PBarcode;
ProductName = PName;
Price = PPrice;
SqlConnection conn1 = new SqlConnection();
conn1.ConnectionString = "integrated security=SSPI;initial catalog=Phusa;server = za211149;persist security info=False";
conn1.Open();
try
{
SqlCommand cmdSearch1 = new SqlCommand();
cmdSearch1.Connection = conn1;
cmdSearch1.CommandText = "SELECT ProductName,Price FROM Products WHERE Barcode=@Barcode";
SqlParameter Bar = new SqlParameter();
Bar.ParameterName = "@Barcode";
Bar.Direction = System.Data.ParameterDirection.Input;
Bar.Value = Barcode;
cmdSearch1.Parameters.Add(Bar);
SqlParameter Nam1 = new SqlParameter();
Nam1.ParameterName="@ProductName";
Nam1.Direction = System.Data.ParameterDirection.Output;
Nam1.Value =ProductName;
cmdSearch1.Parameters.Add(Nam1);
SqlParameter Pri= new SqlParameter();
Pri.ParameterName = "@Price";
Pri.Direction = System.Data.ParameterDirection.Output;
Pri.Value = Price;
cmdSearch1.Parameters.Add(Pri);
SqlDataReader dr1 =cmdSearch1.ExecuteReader();
if(dr1.Read()==true)
{
//MessageBox.Show("Product found");
ProductName= dr1["ProductName"].ToString();
Price = dr1["Price"].ToString();
}
else
{
MessageBox.Show("Product not found");
}
}
catch(Exception ex)
{
MessageBox.Show(ex.Message);
}

conn1.Close();
}

To make your code work as it is now, you have to use the "ref" keyword on the parameters, so that the method can change the strings that you send into it:
public void SeachProduct(string PBarcode, ref string PName, ref string PPrice)
and
search.SeachProduct(Barcode, ref ProductName, ref Price);
To use reference parameters in this ways is rarely used, though. Store the values in the search object instead, and expose them through properties.

Hello
Wait a minute!! I thought setp program does that for you?!! Check the Add/Remove programs in the control panel after you install your app. Otherwise why would you make a setup?!!!

I am displaying images in my application. I want to display the images dynamically by assigning absolute path to the image controls. When i deploy my application in the web server, i could'nt view the images in the browser since it checks for the clients local path. How to solve this.
Thanks in advance.

This is a web app ? If so, how are you managing to load images locally ? If not, how are you loading them and how does the server fit in ?

You need to point to the images using the path to the server, such as www.mysite.com/images/img.gif. If you put a local path, then you'll get a local path.

Any images that you want to display have to be accessible through the web server. You have to use the virtual address of the image, not the physical address, as the browser will be getting the image through the web server, not through the file system.

I implemented an ActiveX control in C#. The interface looks like this:
public delegate void FooDelegate(string bar);
[InterfaceType(ComInterfaceType.InterfaceIsDual)]
public interface IMyActiveX
{
// ...
event FooDelegate Foobar;
}
Now, I'm stuck. I've got a client application for my control written in C++ / MFC and I can't figure out how to subscribe to the event.
Anyone?

Is it possible to determine programmatically whether a perticular software is installed in our system.
For Example
I need to know whether MS Office is Installed in my PC Using C#
If u have solution for this perticular problem then reply me soon with sample Application in c#
|
|
|
|
|
Yes, it's possible.
Check COM object by GUID or COM-interface name in registry.
My english is not so good. Please, correct my errors.
Best regards, Alexey.

Hi,
First of all what do you mean by -
pashje wrote: add a load screen
I guess you want to show a progress bar or some thing like that ?
If i am correct you will have to add multi-threading into ur application, wherein your progress bar will be in some other thread than ur application and would update as you complete the tasks in the application.
You will need some communication medium between the two threads such as global variables ( for example ).
Hope i guessed correctly !

Yep, you are right.. All I need is that! But my problem is with that percentage. I mean how should I make the progress bar increment correctly (for instance the job working on background will accomplished after 50 sec.. then every second my progress bar will increment 2 percent. but actually my program do not know how many seconds the job will take.. so just make a guess ? )

Hi,
You can subdivide the job into some small jobs for which you can assign some predefined percent. Suppose for example u want to copy say 100 files ( I consider this as ur complete job ) then u can increment the progress bar value after each file is successfully copied.
I think this is the only alternative to just depending upon time. You will have to divide your job in some small parts. this is ur best chance for a correct result.
