Question

Code not running - not returning to exit point - noob issue

Asked by: ProWebNetworks

Hey Guys,

I have a form that I am opening, and in the form load procedure I have it calling 2 other procedures:

LookupPriceInfo();
Load_cboTax1();
lblPriceID.Text = PubVar.PriceID;

Then it sets a label.text - however it is as if the code is never getting a chance to execute the 2 items after LookupPriceInfo() - I do not know why my code stops running and does not continue in sequence, it is almost like it is branching off and I am somehow forgetting to send it back to where it started so it can resume.

Below is the code to: LookupPriceInfo()

Thanks!

        {
            
            cn.Open();
            cmd.CommandText = "sp_LookupPriceByPriceID";
            cmd.CommandType = CommandType.StoredProcedure;
            param = cmd.Parameters.AddWithValue("@PriceID", PubVar.PriceID);
            da.Fill(tbl);
            row = tbl.Rows[0]; 
            lblCustomerName.Text = row["CustomerName"].ToString();
            lblCustomerNumber.Text = row["CustomerNumber"].ToString();
            lblProductNumber.Text = row["ProductNumber"].ToString();
            lblProductName.Text = row["ProductName"].ToString(); 
            
          cn.Close();
           cmd.Dispose();
          da.Dispose();
        
        }

is the code you posted, for LookupPriceInfo()?

 

by: ProWebNetworksPosted on 2009-11-02 at 13:30:38ID: 25723962

yes

 

by: HainKurtPosted on 2009-11-02 at 13:31:29ID: 25723969

did you put a breakpoint LookupPriceInfo(); and debug?
when it hits on this line, press F10 to go to next line, if it gives exception you will see..

probably you have these three command in try except block like this

try {
  LookupPriceInfo();
  Load_cboTax1();
  lblPriceID.Text = PubVar.PriceID;
} catch (ex) exception {
...
}

if something happens on LookupPriceInfo, it jumps out of try except block... you need to debug and see whats happening...

 

by: ragbnPosted on 2009-11-02 at 13:31:56ID: 25723974

Looks like there is some exception happening. Use try Catch in your each method and also you can use try case in your main method and see where exception is thrown.

That is what was happening, I checked the output window and saw an exception being thrown. Thanks. I wonder why my code did not simply crash instead of continue to run. I have not employed error handling anywhere.

Oh well, this helped me troubleshoot my issue.

Thanks!
