What 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.

can 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.
I am doing a small project and I am using vb.net with MS access database. I am facing a Concurrency issue sometimes when I try to save data in the datagried view. I have added the datagried view by dragding and drop the table from the data source. Only one user is using the form to save data at one time. I think it works properly unless I moved from record to record then it gives me an error. "Concurrency, 0 records updated from expected 1....."

I have a dataset along with code for validation. When I use a datagridview and setting the EditMode to OnEnter I get the red exclamations telling me that I have an error when this is needed. This works all good. when I click the save button on the BindingNavigator, the application saves the record even when this validation is showing. How do I filter up this validation code through a datagridview and stop the program saving the data? If you need the code for more information, I will add this to the forum.

Currently I am saving data from my applications by saving a text file via a stream reader as a string. I have come to a problem. In my current application, I have an array of the following structure:
[Code]...
I don't need the actual code, but rather, what "strategy" should I use to do something like this:
Somethings I can't change... and must remain as-is:
1. I have to use vb.net to create my vb.exe executable.
2. I have to use a standard DataGridView, NOT bound to any datasource.
3. The text in some columns is obtained from various XML files.
4. The text in the remaining columns is entered by the user (or left blank).
When he exits the program, I have no problems saving (and later reloading) the entire grid. (I just use a small text file.... or should I be using a SQL database?)When the user hits my "refresh" button, the grid is cleared, and step #3 runs again... but there might be some XML files that have been add or removed. So I "match up" the rows it finds in the refreshed grid, with those "user input cells" that I previously saved to a text file.
I got it to work, but it has to compare 100s of "old rows" to each of 100s of "new rows" and find the "similar rows", and "fill in" the prior user data into certain cells. (Thousands of comparisons.)
I need to control a device with a GPIB port. I have the commands that I need to use to do this; but I don't know which is the sintaxis in Visual Basic.
For example if I need to send a instruction like "START:0.01" to the external device which are the libraries that I have to include?, how should I write the programming line to do this?
The main tasks that I need to program are sending data, receiving data, and saving data
I 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. For example, if the user enters 2 rows of data, when he clicks the save button, there are 2 rows saved in the access table but both rows contain the data of the last row in the dgv. Below is the code of the save button.

What I am trying tot achieve is the following:User inputs data in one form that saves to the dataset table no problems. On an edit screen I want the current data saved to appear in this page within all the relevant fields but when saving I want this data to add to the dataset table as an additional line of data so the transaction records are kept.I want to add a new datarow regardless of it saving one change or all 7 changes that are possble.
e.g. Line 1 - user inputs 7 cells of data Line 2 - user amends 2 cells of data Line 3 - user amends 1 cell of data an so on. Unfortunately the terminology for certain items above may not be correct as I am still new to this programming and still on a massive learning curve.At the moment I do not have the code for what I am trying to achieve as I really dont know where to start with it.I am currently able to save the data and have it appear in the "edit" panel however only the cells changed are saved an it overwirtes the initial input.

I 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.
I am able to save the datagridview as an excel sheet but everytime I do it, the previously saved file gets replaced which I do not want. I want the file to be saved with a new name everytime.

View 11 Replieswhat I am trying to do is get a program to load data from a text file with multiple lines in the form "Name, Type, Stocklvl, Price, Location, Reorderlvl" then display it all in a data grid. 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.
