I recently had the pleasure of being featured on Azure DevOps Podcast.  The host, Jeffery Palermo, interviewed me about a topic I’m passionate about “SQL Server For Developers”.  These are features available within SQL Server that make some specific development tasks easy to implement.  Some of these features include: File Streams: “Pointers” that allow you to store a BLOB within the SQL Server File Groups and maintain security over it, not storing it in a DB and bloating the table size. Temporal Tables: Tables that automatically maintain historical changes to every record with a time span of those changes. FileTables: Tables that duplicate a structure of a specific folder, giving developers the ability to quickly query the files one they’re dropped in the folder.   I discuss these topics and more on the podcast.  For the full podcast, please visit http://azuredevopspodcast.clear-measure.com/sam-nasr...

A situation came up where a Windows Forms application required 2 combo boxes filled with customer IDs.  A caption of that form is shown below, where a user must select “From Customer ID” and “To Customer ID”.  Since both combo boxes were populated from the same data column, the natural thing to do was to use the same code for filling both with the same data.  However, this caused an undesirable effect.  When the user selected the “From Customer ID”, the “To Customer ID” was automatically populated with the same value.    To resolve this problem, 2 separate DataTable objects must be used, dtFrom and dtTo.  Although both objects are populated using the same method (dm.GetCustomerIDNames()), keeping the objects separate will prevent one control selection from effecting the other control.  See sample code shown below.               p...

Listed below is an example of using Sorting and Filtering on ADO objects.  This examples utilizes an Oracle DB, but ADO objects can be used with various databases.  In this situation, the entire data table is retrieved in memory.  When needed, that data table can be sorted using a specific column or filtered using the SELECT method with the specified predicate.           public void ProcesssData()         { //Retrieve entire data table into memory gPOLines = RGNdm.GetLineNumsByPO(PO);  //Create a VIEW from the in-memory data table var newView = gPOLines.DefaultView.ToTable(false, "PART_ID", "PO_NUMBER", "CREATE_DATE", "VENDOR_NAME", "INITIATED_BY"); //SORT by desired field gPOLines.DefaultView.Sort = " PART_ID ASC ";   //SELECT (filter) for specific criteria                 DataRow[] filte...

Handling exceptions is a critical task in any application.  When an exception is logged, it needs to have sufficient detail so it can be researched at a later time.  In addition, as a developer, you want to extract and log as much detail about it as possible.  Some of those details include the file name and line number where the exception occurred.  Listed below is a method that handles exceptions, extracts the message, file name, and line number for logging.             private void ProcessEx(Exception ex, string details = "")         {             int lineNumber = 0;             const string lineNumberMarker = ":line ";             string traceText = ex.StackTrace + "";  /...

While working with Oracle SQL Developer , you may encounter the following message when the password is near expiration.   5   A database warning was encountered performing the requested operation:   ORA-28002: the password will expire within 5 days 28002. 00000 -  "the password will expire within %s days" *Cause:    The user's account is about to expire and the password            needs to be changed *Action:   change the password or contact the DBA Vendor code 28002     To change the password: Open the Connections tab (View > Connections) Right click the database where the password needs to be changed Select “Reset Password…”     A pop-up form (see below) will appear prompting for the old and new passwords.     That’s it.  Seems simple but if you’re not familiar ...

Overview : I have a Windows Form application, built in .Net 4.7.2 using Visual Studio 2019.  The form has 3 PartID combo boxes, allowing the user to select 3 distinct part IDs from a finite list of parts in the drop down.     Problem : When the combo box was being filled with values in the drop down list, the following exception was thrown.   Exception : System.AccessViolationException   HResult=0x80004003   Message=Attempted to read or write protected memory. This is often an indication that other memory is corrupt.   Source=<Cannot evaluate the exception source>   StackTrace: <Cannot evaluate the exception stack trace>   Code :         private void cbPO_LostFocus(object sender, EventArgs e)         {             FillPartID1(poLines);      ...
