# Mass Mailer Notes

Local version of MassMailer available at:  [\CAMM NET\Mass Mailer\CammnetThreadedMailer_10172013](\CAMM NET\Mass Mailer\CammnetThreadedMailer_10172013)

*Code notes based on **CammnetThreadedMailer.exe** decompiled by dotPeek.*

## Functions

#### OnStart

This function runs the various services (RunSolicitations [**ProcessNewSolicitations**], RunAddendums [**ProcessAddendums**], RunAwards [**ProcessAwards**], RunCancellations [**ProcessCancellations**], UseTestEmailAddresses) if they are true when MassMailer service is started. 

MassMailer appears not to use DB views. It instead calls to tables such as vendor, vendoraddress, commcodelookup, and the like. Vendor email addresses are grabbed from **vendoraddress**.

#### ProcessNewSolicitations

First set **sql1** equal to the following query. Next, create **DataTable1** - Collect SolicitNums (for use with queries, and Email body/subject):

```sql
SELECT DISTINCT solicitnum, sflag FROM emailtracking WHERE sflag = '0' AND emaileddate is null
```

If there is at least one row of data, then create four more dataTables.

**dataTable2** - Collect specific solicitation's Title, CloseDate, Type, AddendumNum (for Email Body):

```sql 
SELECT solicittitle, TO_CHAR(solicitclosedate, 'MM/DD/YY')" + " solicitclosedate,  solicittype, addendumnum" + " FROM solicitation" + " WHERE solicitnum = " + (string) row1.ItemArray[0] + "  order by addendumnum DESC
```

**dataTable3** - Collect specific solicitation's CA information (for Email body):

```sql
SELECT paname, paemailaddr, paphoneareacode, paphonenum, paphoneext" + " FROM pauser WHERE panum IN (SELECT panum FROM requisition r, solicitinstance s" + " WHERE r.reqidnum = s.reqidnum AND r.reqlinenum = s.reqlinenum" + " and r.reqinstancenum = s.reqinstancenum AND s.solicitnum = " + (string) row1.ItemArray[0] + ")"
```

**dataTable4** - Collect specific solicitation's CommdityDesc (for Email body):

```sql
SELECT commoditydesc FROM newcommcodelookup WHERE commcode IN (" + "SELECT commcode FROM solicitcomm WHERE solicitnum = " + (string) row1.ItemArray[0] + ")"
```

**dataTable5** - Collects all email addresses based on commodities of specific solicitation (for Email TO field):

```sql
SELECT DISTINCT vemailaddr FROM VENDORADDRESS" + " WHERE vemailaddr is not null and vendornum IN (SELECT vendornum FROM NEWCOMMODITYCODE" + " WHERE commcode IN (SELECT commcode FROM SOLICITCOMM" + " WHERE solicitnum = " + (string) row1.ItemArray[0] + "))"
```

Then use **stringBuilder1/2** to build an email with text either about on-line or offline solicitation. 

Then create an **EmailObject** with emailAddresses from **dataTable5**.

*For each* row in VENDORADDRESS, collect **vemailaddr**, **vendornum** and add them to **emailObjs**. When not in test mode, use **SendMassMail** function to send **stringBuilder1/2** contents as a "New Solicitation" email from [e-mail] to the specific vendor email address. Repeat until the end of **dataTable5** is reached.

```csharp
//dataTable5 is vendoraddress records where commcodes match the ones neeeded per solicitation.
foreach (DataRow row2 in (InternalDataCollectionBase) dataTable5.Rows)
{
    EmailObject emailObject = new EmailObject();
    //grab Email Address field (vemailaddr)
    emailObject.EmailAddress = (string) row2.ItemArray[0];
    if (!this.shutdownRequested)
    {
        //grab vendornum for use with emailObject.
        string sql2 = "SELECT to_char(VENDORNUM) FROM VENDORADDRESS WHERE VEMAILADDR = '" + (string) row2.ItemArray[0] + "'";
        string str2 = "";
        if (this.IsGoodEmailAddress(((string) row2.ItemArray[0]).Trim()))
            str2 = (string) this.ConnectOracle(sql2, cn).Rows[0].ItemArray[0];
        emailObject.VendorNum = str2;
        emailObjs.Add((object) emailObject);
    }
    else
        break;
}
if (!this.useTestEmailAddresses)
	//send email with built string body contents to specified vendor email address
    this.SendMassMail(subject, stringBuilder1.ToString(), stringBuilder2.ToString(), "[e-mail]", "New Solicition", (string) row1.ItemArray[0], emailObjs);
else
    this.SendMassMail(subject, stringBuilder1.ToString(), stringBuilder2.ToString(), "[e-mail]", "New Solicition", (string) row1.ItemArray[0], this.BogusEOs);
```
