I am trying to write a code to save and open data that is in my application. My application contains hundreds of text boxes, combo boxes and labels. I have created an array for each set of data, i.e.,
glist(0).store=combobox1.value
glist(0).cat=combobox2.value
glist(0).it=label3.text
glist(0).quan=label4.text
glist(0).total=label5.text
up to glist(89).
Is there a way to write a code to loop through the array and save the values so that they can be opened at a later time in my application? The array will contain Doubles and Strings.

View 10 RepliesI work in an engineering design house and programming is not my actual profession. And I am relatively new to VB .net (previous i had worked in vb 6)
I am working on an in house application. I am coding a simple application in vb .net. This applications takes a few inputs from user and calculates a result. Now I want to implement a simple functionality that user should be able to save the input and results just like most of the windows programs can in a new file format. And user should be able to open the save file when desired.
I am trying to create a console application that does the following:
1) read a text file

I have designed and published my small created app with WINDOWS FORMS using VB 2010 EXP on Windows 7. I can only install the app on the machine that I used to develop the app.I want to install the app on another computer but I cannot. I usually have error reports.
Example:Unable to install or run this application. This application requires Microsoft Common Language Runtime 4.0.3 to be installed on your computer.
what can I do to be able to install the app on a different computer which does not have .Net and does not have visual basic 2010 installed.
find items, they get added to your inventory. But the problem is is that what you have say like 3 items in your inventory, and you close the application, all the items will go away because there's no way to save. So how would I make like the program to where it saves like a .DLL file (preferably .DLL not .TXT so users cant edit easy)? Is there a way to do this like maybe when they get an item, it
View 8 RepliesThis is probably a pretty novice design question. I'm trying to work my way through a number of requirements and give the users the experience they're looking for.I've written a tool that does big calcluation-type things. It currently consists of a class library and command line tool (separate .NET projects.) We're using an Access database format as the file type because it can keep all the various tables together in one file. A few other items about the application: There are not many users. There are no concerns with scalability. There are not great concerns with updates. Desktop is desired. Not web.Using VB and .NET 3.5 SP1
I now need to develop a GUI front end that will allow typical File/Open and File/Save type operations.Users expect that they can open a file, edit it some, then either choose to save it or close it unsaved without any changes being written back to the file. Saving it would obviously save all changes affecting all tables back to the file.
Does it then make sense to use a temp file for something like a proxy then? To, when a user "opens" a file, copy the source Access file to a local temp file and then use that for the editing session? Then, if the user "saves", copy the local temp file back to the source path?
Update: [tagged with ms-access tag too] Also, I omitted the fact that users would expect typical File / Save As functionality too. I think the design I've put in question in this post is what is traditionally called the Proxy design pattern. Has anyone tried this (successfully!) with Access database files before? Words of caution or advice?

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?

My problem is probably ignorance as to how the DGV works, anyway, the problem.I have a bound datagridview which is used to collect user input. Data for 3 of the 7 fields is entered by looping through the rows and progmatically entering common data anfter a 'Save' Button is pressed:
For I = 0 To DG1.RowCount - 2DG1.Rows(I).Cells(4).Value = TextBox1.Text 'OperatorDG1.Rows(I).Cells(5).Value = TextBox2.Text 'DateDG1.Rows(I).Cells(6).Value = TextBox3.Text 'Time NextDG1.Update Prior to this loop I delete the last unused row if its not a new row:
DG1.CurrentCell = DG1.Item(0, DG1.RowCount - 2)If DG1.CurrentCell.Value.ToString = "" ThenDG1.Rows.RemoveAt(DG1.RowCount - 2)DG1.Update()End If
At this point the DGV looks the way it should...All fields completed correctly and no un used ro except for the new row.
After saving :Me.ItemTableTableAdapter.Update(Me.StockMoveDataSet.ItemTable)The 'Operator', 'Date', and 'Time' are not saved to the database for the first row only I have tried EndEdit, Update, refocussing the currentcell/row all to no avail.

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:
Private Sub StaffBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles StaffBindingNavigatorSaveItem.Click
Me.Validate()
Me.StaffBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(Me.GartisDataSet)
End Sub
First of all I am using vb.net(2008) and i have an application which connects to a database and is able to modify it.
My problem is that when I modify a row and try save, It doesnt save to the database although when I add a new record it does save.
Code I use to Save
Me.Validate()
Me.MessagesBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(Me.ServerDataSet)

PS: When I Delete the row it works but when I try updating the database by saving it it doesnt work. Is the Database row event handler able to help my case?
