View 1 RepliesThis is the hardest part of LinqtoSql database handling operations in visual basic 2008 I ever encountered,w/c is the update operation cause Ive been posting this thread several times from the other forum site but noone yet was able to answer my question,examples were given but its not efficient cause it won't specify based on the codes i gave and i know its not easy but im still hoping that one of the answerers of this forum will be able to resolve this particular linqtosql operation codes. I used textboxes in manipulating all data into the database such as displaying records, adding records, & updating records, basically I used with textboxes in doing those database operations. I will give you 3 block of codes w/c corresponds those database operations I used and differentiate from each other inorder for us to determine why one of them has no progress or won't do its operation w/c is the update operation...

I would like you to identify,differentiate, or troubleshoot the block of codes#3, or anyhow, why it has no progress at all or it won't edit and change the records but it runs and no error in regards with its code, and the other 2 blocks of codes were able to successfully do its operations.I was just wandering why only the block of codes#3 is not doing its operation successfully when you change the record being displayed in the textbox.Is there a possible way to edit records in the textboxes?If there is.... Is it possible to debug the block of codes#3 to successsfully do its operation? If you could possibly give an example,can you based it on the block of codes#3?

I know this will have been asked a zillions time before, but I have searched and searched and still can't find an answer,At the moment I have a sort-of-ok php page that uploads picture to the server, emails it then deletes it - same as everyone else.
But, I have been thinking (ALWAYS dangerous) I want to change this so that I can have a simple aspx with smpt varification sent email with an attachment. "Without" up-loading to the server - is this possible and "VERY" simple, as I am just starting out with this stuff.

how to update database with vb.net form
View 1 RepliesI am trying to update a Database via a form. In the update button I Have the below code

It's an appointment scheduler with a calendar layout. You double click a time slot, window pops open for info, then you click save and it saves/updates. Based on which doctor you select from a drop down list, only their patients will show and any appointments you add will be assigned to that doctor. I got that working.Then I wanted to see if I could use a custom form rather than the default popup form, so just as a test, I threw some textboxes on the main form to see if I could get the data from them. Those worked too.Now, when I try adding a new form that will pop up with those same textboxes on it, I get the error "Object reference not set to an instance of an object". Here is my code:
Code: With TestAppointmentDataBaseDataSet1 Try Dim NR As TestAppointmentDataBaseDataSet.AppointmentRow NR = TestAppointmentDataBaseDataSet3.Appointment.NewAppointmentRow NR.ID = Form1.txtOwner.Text NR.Patient_Name = txtFirstName.Text + txtLastName.Text 'NR.Reason1 = txtReason.Text 'NR.Phone1 =
[code]....
That's in the save button routine. I was getting this error at every TestAppointmentDataBaseDataSet line, and for some reason VS has about 6 different numbered versions of this. I don't know why there are so many, but I think that may be why it's screwing up. I got rid of all but one of those errors by trying each numbered version of the data set until the error went away, but now I can't get the last one away. I commented in the code above where the error occurs.
