I am new to Microsoft Report Viewer and trying to a use for the first time. I have just created a blank report in Visual Studio and added a textbox with the valie:
=Fields!vehicle_chassis_number.Value
In Visual Studio, hee is my Code:
data_set = new DataSet();
reportViewer1.ProcessingMode = ProcessingMode.Local;
LocalReport rep = reportViewer1.LocalReport;
rep.ReportPath = @"C:\Users\Jassim\Documents\Visual Studio 2008\Projects\Taajeer\Taajeer\Report1.rdlc";
sql_connection = new SqlConnection("Data Source=.\\SQLEXPRESS;initial catalog=rent_a_car_company;integrated security=true");
sql_connection.Open();
sql_command = new SqlCommand("sp_get_agreement_by_id", sql_connection);
sql_command.CommandType = CommandType.StoredProcedure;
sql_command.Parameters.Add("@vehicle_id", SqlDbType.Int).Value = 1;
sql_adapter = new SqlDataAdapter(sql_command);
sql_adapter.Fill(data_set);
sql_adapter.Dispose();
// sql_connection.Close();
ReportDataSource dsReport = new ReportDataSource();
dsReport.Name = "Invoice_sprocInvoiceView";
dsReport.Value = data_set.Tables["Invoice"];
rep.DataSources.Add(dsReport);
reportViewer1.LocalReport.DataSources.Clear();
reportViewer1.LocalReport.DataSources.Add(dsReport);
reportViewer1.RefreshReport();
rep.Refresh();
this.reportViewer1.RefreshReport();
but I am getting this error message:
Error 1 The Value expression for the textbox ‘textbox3’ refers to the field ‘vehicle_chassis_number’. Report item expressions can only refer to fields within the current data set scope or, if inside an aggregate, the specified data set scope.

How can I prevent the user from closing a Windows Form if a certain TextBox.Text is empty please?
|
|
|
|
|
Hi,
hook into the Form.FormClosing-event and check if the Textbox is empty. If it is, you can display a message box and set the event value e.Cancel = true. This will prevent the form from closing.

hi
This code is helpful for u
write this code in constructor or form load
this.FormClosing += new FormClosingEventHandler(Form1_FormClosing);
then write this method
void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
// Here write whatever condition u want to check
// the condition will true means write this code
e.cancel =true;
}

Take a look at the various resources, MSDN, Google etc, for 'Validation' this will give you lots of ways to achieve your aims.

do not forget to set e.Cancel = false in the starting of event. If you dont then you will unable to exit the program once you set e.Cancel = true

this shows error in c# program...
hoe to assidn it correctly
strToken[tokenIndex++] = a[0];
the quieter u become more u hear
|
|
|
|
|
is it an 'index out of bounds error'?
|
|
|
|
|
Hi,
what does the error say? Maybe it is a type conversion problem. Can you give us the types of strToken and a?
Regards
Sebastian
|
|
|
|

string token is initialised as 0
a is the given input in single dimensional array
error msg is
cannot increment array using ++
the quieter u become more u hear

Is your variable tokenIndex from type int?
Could you post the whole code snippet, please?
|
|
|
|

this is the full code i need to convert ti to c#
{ int tokenIndex = 0;
char strToken[512];
int tokenIndex = 0;
int cntTokens = 0;
int iSymbol = -1;
int prevDictSymbol = -1;
char [] strToken = new char [512];
char [] b = new char [2];
b [0] = '#';
b[1] = '9';
while (b[0] != '\0' )
{
tokenIndex = 0;
while ((b[0] != ' ') && (b[0] != ',') && (b[0] != ';')
&& (b[0] != '#') && (b[0] != '\0')
&& (b[0] != '&') && (b[0] != '-'
)
)
strToken[tokenIndex++] = b[0];
b ++;

That code does not even contain the line you were originally asking about, and it makes no sense whatsoever.
|
|
|
|
|
I pasted this code into Visual Studio and it worked (except that tokenindex is declared twice as the strToken array also).
Please provide the converted code, because that's where the error is.

using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace genAddrTokenVector
{
class Program
{
public void input()
{
int tokenIndex = 0;
//int cntTokens = 0;
//int iSymbol = -1;
//int prevDictSymbol = -1;
//string a;
//Console.WriteLine("ENTER VALID ADDRESS: "); //gets input
//a = Console.ReadLine();
//converting the address to upper case
//a = a.ToUpper();
// Console.WriteLine(a );
char[] strToken = new char[512];
char[] b = new char[15];
b[0] = 'p';
b[1] = 'l';
b[2] = 'o';
b[3] = 't';
b[4] = '.';
b[5] = '4';
b[6] = '5';
b[7] = ';';
b[8] = 'x';
b[9] = 'x';
b[10] = ';';
b[11] = 'b';
b[12] = '&';
b[13] = 'd';
b[14] = ',';
// string s = new string(b);
//Console.WriteLine(b );
while (b[0] != '\0' )
{
tokenIndex = 0;
while ((b[0] != ' ') && (b[0] != ',') && (b[0] != ';')
&& (b[0] != '#') && (b[0] != '\0')
&& (b[0] != '&') && (b[0] != '-'))
Console.WriteLine(b );
strToken[tokenIndex++] = b[0];
b ++;
}
strToken[tokenIndex] = '\0';
}
class main
{
static void Main(string[] args)
{
Program s = new Program();
s.input();
}
}}}
this is my coverted code... it has some errors as well
the quieter u become more u hear
|
|

|

It is not strToken[tokenIndex++] what creates the error, it is the next line:
b++
You can not increment an array. What do you want to achieve with this command?
|
|
|
|
|
i have to increment array elements one by one......
then how to implement tat b++ command
thank you very much for your support
the quieter u become more u hear
|
|

The same way as for the strToken char array. You need another int variable as an index for b.

char strToken[512];
this initialisation shows error in one of my program... how to use this code in C#
thanks
the quieter u become more u hear
|
|

You have to write it like this:
char[] strToken = new char[512];
Btw does the answer before solved your b++ problem?
|
|
|
|
|
no even after initialisation it shows this error msg
Error 3 Operator '++' cannot be applied to operand of type 'int[]
the quieter u become more u hear
|
|
|
|

As said before, you cannot use the increment operator on an array. If you want to iterate through the b-array also, you have to use another index variable, like intbIndex. Then you can use the increment operator.

I used the below code and it worked fine
int tokenIndex = 0;
string[] strToken = new string[3];
string[] a = new string[2];
a[0] = "9";
strToken[tokenIndex++] = a[0];
Console.WriteLine(strToken[0]);
