How does one set Originator (or From field) in an e-mail. I have tried setting RecipType to 0 together with RecipAddress and RecipDisplayName but keep getting an error when I try to set the RecipType to 0. Does anyone know how to do this and why is there such a woeful lack of documentation on this control?

View 6 RepliesIm writing an app which connects to a SQL Server database, via datasources / datatable.When Im looking at my .xsd I can see DataTables containing DataColumns. Each DataColumn has a 'NullValue' property which defaults to '(Throw exception)'.Because I have nulls in my tables I have gone through the fields and set all System.String fields to NullValue = 'Empty', System.int32 field to NullValue = 0.

What i am trying to do is set up a datagridview on a form that shows the summary data. The time is controlled on the form by a trackbar (output to textbox) and I started setting up a loop using (For/Next) to isolate firstly the matching entries in field 3 (time). This works fine. I then used compute to sum the the field 2. However what i want to do is to loop through table 2 and where entries match i.e. where Field 1 in table 2="A" sum matching entries in table 1 where the DateTime matches.

In our projects we use setting variables to store user setting for the applications. Moreover, with every latest version of the applications, we upgrade these variables to retain user settings.Normally, this works fine, but recently one of my end user reported an error i.e.Configuration System failed to initialize". The error is related to user.config file. Therefore we requested the user to send us his file.After received the folder, we noticed that it contains 3 files (3begfjb.newcfg,3begfjb.tmp and user. config). 3begfjb.tmp is an empty file, while 3begfjb.newcfg and user.config are identical files. We tried to open these files but the data in user.config isn't proper xml rather its unreadable formatted file.Do any you guys had experienced this sort of issue or any ideas how and what may have created these files and corrupted user.config file.

I want to change the DoNotMail boolean value represented by a Gridview checkbox and automatically update in the database if the checkbox is checked from 0 (False, Will Mail) to 1 (True, Won't Mail) here is the code I used. [code]...
is it possible to do a two way sync on the entire gridview when the user hits a button so you don't have to do an update every time a row is changed? because the user might check the box and then check another box then uncheck a box and it would be a lot of updates...

I am creating a database in VB.NET for a movie rental place. I currently have three forms;
Member Information
DVD Information
Borrow DVDs
What I would like to do is when I am viewing a member's details, if I click a button 'Borrow DVD for Member', the member's ID number transfers over to the Borrow DVDs table in the Member ID which also would hold some information from the DVD Information table, but I'm sure if i can figure out how to do this firstly, I will be able to apply the same rule and work it out myself.I have been trying to use a query statement like;
INSERT INTO [Borrow DVDs].[Member ID] [IN goodstuffvideos.mdb]
SELECT [Member Information].[Member ID]
FROM [Member Information]
but that has been coming up with error codes and completely not working.
Borrow DVDs table fields are: Borrow ID, Member ID, DVD ID Number, Hiring Fee, Borrowing Limit?
DVD Information table fields are: DVD ID Number, Title, Rating, Hiring Fee, Borrowing Limit Member?
Information table fields are: Member ID, Family Name, Given Name, Address, Town/Suburb, Postcode?
The error coming up is; Error in INSERT statement. Unable to parse query text.And under that it says The query cannot be represented graphically in the Diagram and Criteria Pane.

View 3 RepliesI think the way to do this in VBnet involves binary math? -- no "easy" way I don't think (like picbasic mybyte.0 = 1 mybyte.1 = 0 etc).I know you can read a bit by using convert.toint32 (2^0) (2^1) etc. and comparing to an integer value but my head is going in circles on how to set (write) a bit value. I need bytes because I intend on writing to the serial port.If bit0 is 1 then mybyte bit 0 = 1.
