Edit Sql Database Using Forms?
Apr 12, 2010
I'm trying to edit my sql database using VB Forms.I went ahead and connected my database to VB and I see how to pull data from my database to VB, but I'm not understnading how to use a form to add/edit/delete data from the database.Basically I would be looking to add to a table:
Table Name: People
Row 1: First Name
Row 2: Last Name
Edit would be the same type of thing except I think I would pull the data from the database to populate a table, than how would I save the changes after I changed the information To delete I'm assuming would be similar to edit I would simply pull the data from the database than using a delete button would delete it.What I don't understand is how to create the SQL statement in VB so that it'll execute it properly in my database.

When in "Add" mode, I have all controls on the form enabled with the exception of a listview that is disabled until the record is saved. The listview needs the primary key from the saved record in order for items to be added to the listview.
When in "Edit" mode, the form is populated when a record is selected on a search form. Specific controls are disabled. When a value in a control is changed, I have a RecordModified property that is set to True and then the Save button is enabled. I also have combo boxes that need to be populated but the selected value needs to correspond to the value pulled from the database

I have RTB witch I can edit with text by using .
RichTextBox1.text = RichTextBox1.text & "stuff" & VbcrLf
Great but I loose any editing to colour/font I may of done previously. Is there a way of just adding a new line. I am thinking along the lines of finding the last character then adding my new line.

I'm having trouble with setting a datagridview's cell in edit mode, or rather, to let the user type some input on load of a form (as in Excel or the like).
This is my code (after the dgv has been filled):
dgvTentander.EditMode = DataGridViewEditMode.EditProgrammatically
'(or dgvTentander.EditMode = DataGridViewEditMode.EditOnEnter)
dgvMyDGV.CurrentCell = dgvMYDGV.Rows(lastrow).Cells(TeCOL_Quant)
dgvMYDGV.BeginEdit(True)
The code correctly indicates that the cell is selected, and when the page is loaded I can still se the cell selected, but the cursor doesn't appear and nothing happens when I type.

Recently I've created a window database program(Tools Inventory); everything works fine except for the following two :
1. It doesn't accept modifications to the existing datas in the column & rows. (Error : Updates require a ValidCommand......)
2. Remove button does not delete the data in the database. It only works in the runtime.

I would like to loop through my database and edit a field. For some reason the last value of the FOR loop is being saved in the field. What should happen is that the ZonePos field should be filled with value 1 to how many records in the table. Currently lets say there are 5 records in the table, the value 5 is saved in all the rows.

I've been at this for a bit now, and I have tried using google extensively. I have my application set up: it is a HWID System available only to paid subscribers. I want buyers to be able to click on a 'buy now button', and once they successfully pay it automatically adds their information into the database the app uses. This way there is no waiting after payments. I know this is possible, because I've seen it done before - I just can't seem to find how it works?
