View 5 RepliesSaving New Selection From Combobox To SQL Database?
Jun 17, 2010I have an app I'm working on with multiple forms. One of the forms, frmLocationInfo, has textboxes and comboboxes which are automatically populated based on a combobox selection from a previous form, frmLocations. I've been able to get any changes made to frmLocationInfo's textboxes to save to the SQL database, however, when attempting to select a different item from any of its comboboxes, it's not saving to the database and instead, I receive a "Procedure or function...has too many arguments specified" error.
Here is the code for the Save button:

ComboBox Display On Screen And Saving Content To File
Apr 26, 2010What I am attempting to do is make a form for a tire shop. I want to put comboboxes on the left side of the form that the employees make choices from. I then want to put some kind of a table or grid looking thing on the right side of the form that will display their choices so that everyone in the shop can look at it see that "John is on bay 5 until 3:00pm". At the end of the day I want all of the combobox choices to save to a file..I dont really need the table or the grid thing to save..just the choices. If I want to do this, do I need to use that gridview tool? or can I make my own table thing to display the choices in.

Dec 7, 2011I have a datagridview which has columns which are bounded and unbounded. My problem is when the user enters several rows in the dgv, only the data found in last row is saved in the access table.

Saving Data From A DatagridView?
Sep 17, 2010What I have is a program that is going to monitor and store different stats about different email servers. The basic layout of the main form is a datagridview. Now this program does not need to store the information into a database as it is only going to run on one machine which is why I did not bind the datagridview to a dataset. Maybe using a datagridview is not the way I need to go but researching around the only other option would be to save the data to XML. However since the table does contain hidden fields with authentication credentials, I am a little bit hesitant about doing so.

Saving Data Using Datagridview?
Oct 22, 2009can anybody please help me with my problem. I have a database and I view the data using a datagridview, the problem is I cant update my database using the datagridview properly because there is an error in my codes. I just cant understand what I should do to make it run. I know there are lots of post about updating database using the datagridview but none of them is the one I am using. Please review my codes and tell what is wrong.

The error says that "the variable @a has already been declared..." As you can see I did not use the Me.Validate etc. to update my database because I do not know how to use them and I would like to focus on using this kind of codes in my program. This is the reason why the post about datagridview here are not useful for me.

Saving A Bound Datagridview - AutoSave Or Not
Sep 22, 2011I have a datagridview created for my windows form using 2005 and I'm debating which would be the best way to allow my users to save the records.
The datagridview contains a Delete Checkbox so if that's checked, I need to delete the record. They will never be inserting new records - just updating or deleting them.
Do you think it's best to give them a Save button and when it's clicked, save the records; or rather, have it auto-save after each modification. I'm not sure how this would work in conjunction with my Delete checkbox though.

From where it can be viewed and edited as well as saved back into the original file stock.txt as well as generating a separate file reorder.txt which includes data on what needs to be reordered and the date which updates on program exit. I have chosen to use datagridview something I'm unfamiliar with as I figure It'd probably be the most functional to meet my needs of displaying a lot of data clearly as much as 200 items.
View 22 RepliesDataGridView - Saving And Restoring Column Order?
Aug 26, 2010Sometimes I select a value in my Combobox by hand, and sometimes the value to show is chosen elsewhere in my program logic. I want to carry out a certain action only when I have chosen a value by hand, and not when the value is changed by the program. For this reason I use the DropDownClosed event (and not, for example, SelectedValueChanged or SelectedIndexChanged). This works fine, but if I set AutoCompleteMode of my Combobox to Suggest, selecting a value from the suggested list doesn't fire the DropDownClosed event (perhaps logical, as the actual drop down list doesn't actually open).
