View 1 RepliesWhat 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.

Using VB 2008 Express, I've constructed a simple database type app for saving contacts. The table data I save at design time is always saved correctly but data entered at run time seems to get saved even after closing the app and VB. However, after restarting the computer, the newly entered data is usually gone. Why would this be? I've seen a few video tutorials on creating simple database apps and did everything they did and am getting the same problem. I thought it was a configuration problem so I actually re-installed Windows and VB 2008 Express (as well as 2010 Beta 2). I have noticed that in the database explorer, the .mdf file has a red x to the bottom right of the yellow database icon and when I click the + it seems to turn into a black plug. Is this normal?

View 3 RepliesI have made a application that detects already saved hotkeys and data assigned to them, so now whenever I press the hotkey to send the assigned data to active window it does sends the data to active but it won't stop sending data...I am calling my function that reads data from the database in timer device and the function that detects the hotkey...
Here is my code
Private Sub Hot_Checker_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Hot_Checker.Tick
gKey.CheckBox()
'is the object that calls the function to check the pressed hotkey
keyTemp = gKey.getHkey()
[Code] .....
trying to find the main error that is causing this to happen, after pressing the hotkey my app won't stop sending the data to the active window. My app should wait for the next hotkey press rather than sending data.

View 6 RepliesI am having a hard time figuring this out. It's about ExecuteNonQuery() method and sql server database. I done several testing and still getting the desired result which is data captured from application window and saved into sql server database table.

If i run the program in debugmode and then do a update it will be saved to the database.(must stop and run again to see the update. How to se the update directly?)
My main problem is that if a build the program and run it outside VS then update never being saved. How can i solve this. I tried using "commit"(maybe totaly wrong) but that didnt work.
I currently save the data the user input into the textboxes like:
[SAVEACCOUNTDATA]ACCOUNT[/SAVEACCOUNTDATA]
[ACCOUNT0]Graham[/ACCOUNT0]
[ACCOUNT1]McCann[/ACCOUNT1]

[ACCOUNT3]graham23s[/ACCOUNT3]
[ACCOUNT4]********[/ACCOUNT4]
when reading it back into the textboxes i was needing to chop off the surrounding parameters:
[]Just need this data[/]

View 4 Repliessince I still use VB6 and the code is in VB8, I can't find the solution.The sub below is executed in a button's click event, and is supposed to save data to his database. It seems to work fine : you can add persons (in a separate form), and see them appear in the datagrid. You can stop the program, go back to the VB editor, and run it again (without rebuild), and the previously added persons will still be visible in the datagrid. But...If you add some persons, then go to the editor and force a rebuild (for example by adding more code), and than run the code again, the the previously added persons are gone (nomore visible in datagrid)!To me, it seems that the problem is to effectively update the database. I have searched on the internet about this topic, and I read that you must "set" the UpdateCommand.
