Database Won't Update From Popup Form

Aug 14, 2009

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.

Update A Database Row With The Update Command?

Feb 11, 2010

is there a way to update a database row with the update command by first defining all parameters and then all values just like you can in the insert command? "insert into table1 (parameter1,parameter2,....) values (value1, value2,....)"something like "set table1 (parameter1, parameter2) values (value1,value 2,...) where ...."?because I only know the syntax to define each parameters value "set table parameter1=value, parameter2=value2... where"

I was using 2 forms, the first one has general data capture and the second one is a calendar form. On Form1 I have mulitple windows controls. A Textb ox and beside a Calendar button. When I click on a Calendar Command button, it should open calendar form and once the user selects the date, the date should be placed in the text box on the form1.

I dont want to use several global variables b'coz I might need multiple validations as above. Please help me on this.

Update Open Child Mdi Form Textbox From Parent Form?

Feb 3, 2012

I have a date selector on mdi parent that updates a property when date is changed. When I open a child form, it grabs the property just fine. However if I change the date again after the child is open the date does not change on the child unless I close and reopen the form as expected. What would be the best way to automatically update all open child forms when the date is changed on the parent at anytime? running a timer to parse the date property is impractical.

Update A Database With A New Row?

Jul 8, 2011

Ill start this by saying im still very new to VB, ive had some programming expereice here and there since high school, but never really did much with it till now.Ive got a small app that im working on for a side project, i want to add the details of a given days records from a simple POS system i have built up so far. At this point i have all of the information generated and i cant seem to get the app to commit it to the database. I have seen tons of posts on this, and i have followed a bunch of them to no avail. Im sure this problem is because i have the code written wrong, and i cant get it figured out. Here is the code that im using to try to save the data:

Dim hoursworked As TimeSpan = dtpEndTime.Value.Subtract(dtpStartTime.Value)
hours As Double = Math.Round(hoursworked.Hours + (hoursworked.Minutes / 60), 2)

Update Database Using SQL Through VB?

Jun 12, 2011

I'm currently working on my A2 computing project, and I am having slight difficulties updating and saving the data in my database when it is entered on a form in VB. I cannot find any reason why it wouldn't work, but if someone could suggest a better way to do it, it would be great as everything else works. It's in the btnsave at the bottom, and when you click the button on the form it come up with a very unuseful error, which is no help to anyone.

This is the code for the edit details form, where on loading, the customers details which are currently in the database are already there, and they can change things on it and save it to update their details if anything changes.

Public Class EditMyDetails
Dim con As New OleDb.OleDbConnection
Dim dbProvider As String

Best Approach To Update A Database?

Jul 18, 2009

I am writing a program to assist Paramedic students in learning the Drugs that they have to know in order to pass their classes. I have created an Access database to hold all the information on these drugs, but not every student that will use this program will need to learn all the drugs contained within this database.

Right now I have 43 drugs in the database and still growing.

What I want to do is to present to the student the drugs and have them say "Y" or "N" as to whether its on their required list to learn. That way they only work on the ones that they need to.
