• Windows Forms Cloning Forms

  Hello, I have a series of forms that are very similar, but they contain different editable fields, and different columns in a DataGridView.  I would like to ensure that all of the Forms and controls have the same property settings in order to ensure that they appear and behave identically.  Right now, I am using a written checklist and sometimes I miss an item (my bad!). I've thought about creating an abstract Form class and subclassing my cloned forms from it, but that didn't work out very well due to the customization code that was necessary for each Forms view.  Is there an easy way to save the properties of a Form and DataGridView, and then to programmatically apply them to a new Form and DataGridView   ...Show All

• Visual FoxPro Can't access DBF with memo through ODBC (was Memo field conversion)

  I am using a Microsoft ODBC Driver to connect to 4 DBF files . One of them has Memo Fields in it and I am not able to see this particular table when I try to import it in Access. All the others I am able to see and they do not have memo fields. Any idea guys How I can fix this The thing is I am no FoxPro Expert , I get DBF files from some one and my requirement is to import these in Oracle Tables through an ETL tool. But before doing that I am trying to pull these files in Access and while doing so I am not able to see the Table with Memo Fields. I asked the user to change these fields to fixed length. They resent me the new table (no memo fields) and now access recognizes the table. So I was wonde ...Show All

• SQL Server Flat File Connection Manager HeaderRowsToSkip not modifiable at runtime?

  I have been working with flat file connection managers for a while now, and I have found it very useful to set properties on all types of SSIS objects using expressions that are set to SSIS package variables. We have recently moved towards using a centralized application configuration infrastructure, so we are now loading up all application configuration information from our own system -- it's actually based off of the 2.0 ConfigurationManager. I have developed a custom control flow task that will retrieve all of the SSIS variable information from our own application configuration system and set all of the SSIS variables as the first step in a package. When I have been using this to set the SSIS Variables which are used in exp ...Show All

  I have a Ipaq Pocket PC.  It connects to a bluetooth GPS Receiver (COM6).  Whenever I try to open this COM Port using the SerialPort component I get an IOException.  I have even tried listing all COM ports on the PPC, and opening each one inturn.  Some work and some throw an IOException. Does anyone have a suggestion I think you will find that even though an IOExeption is raised, the serialPort is still open. put a try catch block around the open method, and do nothing. after opening the port, try reading/writing to it.

• .NET Development DataTable.Merge() method help, not persisting changes

  vb2005 hi, im implementing a sort of AutoBackup feature for a bound form in my app. every 5 minutes i save the datatable's changes to a XML file. if my app crashes, next time i load the form i get the recover screen, which loads the XML file back in, merges it with the current working datatable (last saved one from database). problem is when i update the datatable back to the database. the columns that i merged back are not being persisted to the database. the only way to get them to persist is to go to the TextBox bound to the column, make any change there, and then update the datatable. something is wrong here, let me show a bit of the code: '''' THE CODE THAT SAVES EVERY 5 MINUTES TO XML STORAGE: If MySQLDataset.HasChanges() T ...Show All
