Question

I was just wondering how to pass SQL to crystal report. Right now I am only able to load a premade report onto my crystal report viewer. Now, I want to be able to put in parameters for building my reports. Here’s some code…

    private void btn_InventoryReport_Click_1(object sender, EventArgs e)
    {
        ReportDocument inventoryReport = new ReportDocument();
        inventoryReport.Load("C:\\Users\\Wilson Kao\\documents\\visual studio 2010\\Projects\\Wincent Warehouse Management Studios\\Wincent Warehouse Management Studios\\InventoryReport.rpt");
        inventoryReport.Refresh();
        crv_Report.ReportSource = inventoryReport;
        crv_Report.Refresh();
    }

Right now, I want to be able to add SQL to filter out the report, something like this

da.SelectCommand = new OleDbCommand("SELECT * FROM InventoryView WHERE vid = @vid", cs);
da.SelectCommand.Parameters.Add("@vid", OleDbType.Integer).Value = vid;
//Make Report Based on this SQL

I tried this : http://csharp.net-informations.com/crystal-reports/csharp-crystal-reports-sql-query.htm

but it said i’m missing an assembly or something like that (prob a 64/32 bit incompatibility) but hopefully theres something else I can do. Thanks!

Solved. Looked into the bug and it said that I actually needed to move some of the dlls into something called dotnet1 folder (it wasnt there I had to create it myself). After that I had to modify app.config and it worked. awesome
