View 5 RepliesModify Code From Existing SerialPort?
Sep 21, 2009I've seen this great example of serial communication in VB.NET[URL]..I try to use it in a project I am working on but somethings are not clear to me.1: Now the send and received data is shown in one RichTextBox but I would like to split this into two RichTextBoxes (RtbSend and RtbReceived).It is unclear to me how and were data is assigned to the RichTextBox?
2. the received data is shown in the Richtextbox as one long line, I would like to get a new line for every send message.So for example: I I send "test" four times, I would like to see:The example describes that "comPort_DataReceived" is executed when data is waiting in the buffer. Where can I see the eventhandler responsible for this? How does it know data is waiting?The problem is this kind of coding is a bit to difficult for me. I want to understand the code before I implement it into my project. I understand most of the code but this is unclear to me.
Modify The Code Behind The Database In VB2010?
Sep 22, 2011mostly the data inside the datatable is always typed by ourselves, while in this case, i want the computer itself do caculate or whatever and then input in this table and finally the chart will get the data inside the table and then draw the line automatically.is there any sample codes for me to know....(Above is just a simple idea, actually my project is to record the time spent in 2 status(working and idle) and then do the database table. but the GUI should look similar to the image above)

VS2008 Query - Modify Code To Search For Items Containing Specified Characters
Jul 3, 2010SELECT ContactID, FirstName, LastName, Male, Female, Email, Address
FROM Contact
WHERE (FirstName LIKE @FirstName + '%')
The above query works and returns values on first names that begin with whatever item I type in a text box.
How can I modify that code to search for items containing specified characters instead of just searching for items that begin with the specified characters. I would still need to use a wildcard because it is a search field. see below for an example
For example can I query the FirstName column to display people who's name contain the letters "an" in that order a before n but anywhere within the word e.g.
- Anna
- Jane
- Samantha

DataRow Collection - Update Requires Valid Delete Command?
May 1, 2010I'm going through a book which is teaching me some basic coding principles of the language. The current section is detailing how to set up a master child form using two tables linked with a foreign key. The master table is displayed as a number of text boxes, and below is a grid with the child table which shows related records to whatever master record you happen to be checking out. At the top of the screen are the default navigation controls that are added with the grid. The master table is named Person and the child table Book. They are linked using a foreign key and have cascade set up on them.
The book informed me of the code required under the save icon on the navigation control so that when it is clicked both tables will be updated as required. It is as follows:
If Validate() Then
'Make sure editing has completed on both master and child tables
Me.BookBindingSource.EndEdit()
Me.PersonBindingSource.EndEdit()
[Code] .....
I have double checked that the code matches that shown, so this should in theory work fine. But if I manually delete a record from the Book (child table) grid and then click the Save icon on the navigation bar it comes up with the error "Update Requires A Valid DeleteCommand when passed DataRow collection with deleted rows".
Why changes made are not permanently saved to the database? I gather that it's using a "copy" of the data in the database but how do I get the code/form to make changes to the actual underlying database records as well as just the copy? I find this system very unusual, if someone deletes a record in the application why would anyone want this to be just done temporarily?
