Hi how's it going. In the middle of coding a banking application for a project. Part of it involves mortgage interest repayments. Was wondering if there was any way of logging the time a new record was created and added to the database and then adding interest to the balance owed periodically every 30 days..
View 3 RepliesCan anyone tell me why "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound." I keep getting an error "Invalid Operation Exception was Unhandled" error. All I am attempting to do is allow the user to select products from a list(or a second datagridview) and have it added to the datagridview so they do not have to type in every cell since the other cells are not visible because they do not purtain to their needs. Plus they will be able to save all items at the same time.

I have two datagridview's both are databound. First one shows items for sale and the second stores all the items that were sold. I am trying too transfer selected rows from one to the other but no matter what I keep getting told "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound."
View 2 RepliesI have a datagrid that loads at form time with the current database Information, when the user types in there username and password it updates into the database like a registering program, but the problem is i can only see the updated database when i restart the program. here is my code for INSERT [code] You'll notice im using Command Method instead off a Adapter, as i only had problem after problem with the adapter the command method seemed to be the better option as it worked straight away. When ive researched ive got information like used "SetDataBindings" also just so you know i don't have the option for some reason, also Refresh() Doesnt work either.

The idea with this form is to add the futures which is calculated when the button is pushed but I need the list to update every time and show the values each time to which the previous value is added to the new calculation, e.g. of what it should look like in listbox:
Year 1: $1,290.93
Year 2: $2,724.32
Year 3: $4,350.76
etc....
I have been working on this a while and I am at a standstill, I was given a function to clear the form everytime it calculates but I don't know how to implement it, I am new to VB. Here is what I have so far:

View 1 RepliesBelow:
datBrakePointsX.Rows.Add(strA)
produces the error 'Rows cannot be programatically added to the DataGridView's rows collection when the control is databound.'
To my knowledge, this is an empty grid. I am adding data manually and the code below works if I remove the line. The problem is I need to add the next line.
Private Sub cmdAddX_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdAddX.Click
' Find the first blank cell
For c As Integer = 0 To datBrakePointsX.Rows.Count
If Len(datBrakePointsX.Rows.Item(0).Cells(c).Value) = 0 Then
datBrakePointsX.Rows.Item(c).Cells(0).Value = c

2. and another beginner question.. how to i declare a string that spans multipe lines? i tried with the + operator like in c#, but it doesn't work.
Access <asp:table> table rows added by javascript in asp.net webform . Apologies for the duplicate question but I'd really like an explanation why this is the case. It is probably due to my lack of understanding on how browsers process HTML tables on submission to the server.If I have a <HTML> table or an <asp:table> control on an aspx page and I add rows to it client-side using JQuery / Javascript, why can I not include these added rows in a post-back to the server?
I've been trying to get this to work and it looks like I can't do it based on the answer to the previous question. But can someone explain why this is the case? The table itself can be returned in the post-back but the only rows present are the rows that were part of the table when it was sent to the browser originally - it does not include the rows added by the browser.there was a way to include these new rows in the post-back, the same as any client-side user input?

if could modify the following code for me so that it save data row by row from a DataGridView into SQl Server. Currently, the code saves data from all rows at time instead of saving only the recently added data in a row or rows when the user clicks a button.[code]...
View 1 RepliesI have a DataGridView which I AllowUserToAddRows behavior enabled. I want to be able to force that only one row be added at time, then if the user clicks the save button the row is inserted into the database, and then another row may be added if the insert was successful.
The reason I want to do this is to get the last inserted id and insert that information into another table.

I can finally filter my DataGridView every time a checkbox is checked or unchecked. However, I do not need it to filter out all of the messages each time a row is added, so I just need to check the current message. The following sub's demonstrate how I am doing this.
Public Sub FilterAllMessages()
'Show all rows
For Each showBand As DataGridViewBand In MessagesDataGridView.Rows
If showBand.Visible = False Then showBand.Visible = True
Next
[Code] .....
Great, they both work as intended...but I believe I am losing out on efficiency with the way I have this. I have tried adding another public sub CheckMessage() to run through the row, pretty much doing what each long list of If/ElseIf checks does.
IN the FilterLastMessage() I just call CheckMessage(), and in the FilterAllMessages() I call it like this:
For Each band As DataGridViewBand In MessagesDataGridView.Rows
CheckMessage()
Next
This isn't working as it is unable to get the index for each message when I have it FilterAllMessages(). I'm just wondering about making the 2 sub's above more efficient so I can have it CheckMessage() just once, instead of it doing basically the same thing twice. Also, the messages all go on to a DataGridView, and this will be constantly writing messages to the window. After a while I would imagine that this will bog down the program, so I am wanting to keep the number of messages that are displayed < 2000. How is the most efficient way to achieve this?
I have a form in which I add 9 labels in Run Time with .add method inside a panel. When I try to remove those labels in Run Time using For Each Loop, only 5 labels get removed. My code is given below.Code to Add Labels
While rs1.Read()
channelid = rs1("s_id")
Dim channelLabel As New Label[code].....
When i run the loop without .remove and .dispose it alerts .Text of all Lables present inside that Panel and With .remove and .dispose it does not remove all Lables and does not alert all .Text. In other words it misses 1 after 1.
I have this application which has one class. I need to return a recordset of data to the calling form. If i use Properties to return, it can only return only a single value at a time.

View 1 Repliesi am using vb.net 2005 and i want to know the event name for a listview that happens every time an item is added.
View 1 RepliesI found that there was the Settings.Properties collection as well as the Settings.PropertyValues collection, and hopefully i'm not doing extra work here, but i'm creating both, and then assigning a value to the Settings(PropName).
Defaultly, in my "static" settings (through the IDE designer window and such) I have 9 settings/properties, and at run time when I'm processing, the Settings.Properties.Count doeos indeed equal 9.
Now, in the process of my application I generate some "saved" control properties myself, and actively "add" them to the Settings:
For Each prop As String In Me.Keys
Try
name = Layout & "." & _control.Name & "." & prop
[Code]....
This seems to work fine, and after the repetitive code (cycling through a collection) is finished, the Setting.Properties.Count does indeed equal 79, for the 70 new properties added.
I not only execute a My.Settings.Save() when the application exits, but I know I also have the SaveMySettingsOnExit set to true, but the next time i load up the app, my settings.properties.count is back to 9.
