Info Not Saving In A Database?
Apr 11, 2010
I created a database in access 2007, linked it to my project in visual studio 2008 (vb). When I enter some data using the UI, it does not save it in the database, and it's gone as soon as I run the program again. I dragged the textboxes from the datasource panel, onto the UI..
this is the code that was automatically generated by vs for the save button:
[code]Private Sub StaffBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles StaffBindingNavigatorSaveItem.Click

I have a database, and I am creating many forms that pull info from the db and write info to the db. I have a form that asks for a set of information. One of the box is a combobox that has a list of values. I have a button at the bottom
of the form that will allow the user to enter a new value to the values that populate the combobox if the user does not see the value they need. This will obviously populate a new form to create the new value.
I want the information on the first form to not be lost when the user hits the button to enter a new value for the combobox, yet I also want the combobox to display the new value.
Is there a way to save the information from the form and repopulate the form with the info the user entered? If I reload the form undoubtedly the form will repopulate the combobox and my new value will be there, since I have it reading and pulling info from the db on loading the form.

I have this form that i need to save on Mysql database but i'm stuck on what I should do.
This form needs to be done every 3 or 4 months. Every saved information stays saved in a row.
This form has alot of radiobuttons,textboxes and comboboxes that I save into mysql database But I also have a datagridview inside that form that needs to be saved as well , So here is where im stuck
I need to keep things simple and efficient. heres two example of what i can do but don't know what to use.
On MYSQL
Example 1:
-User1 Review 1-
Row1(review1) ----info--info---info---info---info----info---
Row2(review2) ----info--info---info---info---info----info---
Row3(review3) ----info--info---info---info---info----info---

I am trying to get my project to be able to save the data been input from a user. I have uploaded a screen shot of the dialog I am currently trying to use. You will see that I have got a combobox for member at the top. What I want is when the "new" button gets clicked then I can add the desired information then click "Ok buttton which will then save the information.
I want to be able to select members from the combobox after multiple have been recorded to be able to delete or edit them. I have got as far as "changing" the combobox to a textbox for input purposes. I have tried a few attempts to get it. I am getting "ConfigurationErrorsException was unhandled"

I'm making a program where the user fills out info, then they click one button and the program takes a screenshot of the form, then they click another button and the screenshot gets saved. I'm having a couple problems with my code though. For one, I'm trying to make the screenshot go to an invisible picturebox to make saving easier, but I cant figure out how to make the image go to the picturebox. The other problem is that I want it to automatically save without showing the dialog, but so far, it won't save.

I have a gridview with four template fields that I need to be able to put info into to save to the database. When I hit the edit button and my columns change into edit mode I can enter information just fine. But when I try to loop through the control to get the information it doesn't pick anything up?

So I'm having more database problems. The specific problem I am having is that I am trying to update a DataGridView to display new information that was input into the database programmatically. I have tried several methods, but none have worked, and one actually "broke" the program. So I am in need of some more assistance.
Here is the current code that I am trying to use to update the view (this contains pretty much everything that I have tried up until this point):

I have been tasked by my boss to create an application that takes information from an excel database holding sales figures, margins, budgets etc calculates all the figures and exports the totalled values to a table and graph also in excel. Although this is fairly easy, there is some complications I am dealing with. In the database there are many territories, and each employee has 1 or more territories.I'm not sure what I have done wrong, however the totals are not adding up properly. My code is:

class names (i.e. Year6 Dragons)
Students names (i.e. Sarah Jessica Parker)
I want the design to look very similar to the form used in MS Access for the query wizard, which will allow me to choose a class and then specific students.

What I am trying to do is get specific info from a database and what I am getting is the first entry.
I have made a database connection, made the top bar not visible and I have inserted a text box and multiple labels. My MDB database has 3 columns (street, city, postcode) and multiple rows.
What I want is when a user enters a postcode in the text field the other labels get the info related to it. I.E. when a user enters "FY1 3DL" the labels update to "King street" and "Blackpool". With the code below I get the first row from the database.
Code:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.StreetsTableAdapter.Fill(Me.WcipcodeDataSet.Streets)
End Sub

I'm writing a program in VB.Net and loading the info into a SQL database. Debugging it works fine on my machine that I am programming it on, it connects to the database and runs through all the info perfectly. However trying to get it to run on another machine it will not connect to the database. I realize the reason for this is the connection string, it's looking specifically at the file directory for the database. How do I change this so that it will function on any machine. The program is only intended to run on one machine at a time and not over the internet.
