Get rid of the Try/Catch block for now and let the code throw the exception. We need to see the exception messsage to know what it's complaining about. Your code is hiding the exception behind a non-description messagebox that doesn't give any useful information.

That's not the entire exception. What does the Message property say in that exception?

Hey
I have an application integrated with Microsoft Outlook 2003. This application also runs Macros in Excel and then saves the workbook. The save can take a reasonable amount of time, so at the moment I bring Excel to the front so the user can see the program hasnt crashed.
This is a bit of a bodge and looks untidy so is there a way to get Excel to notify my application of when it has finished saving?
I though about trying to hook into the Save event and then callback when it has done but I was wondering if there is a simpler way so that I can just implement a progress indicator or another way of telling the user the app is busy.
Thanks
Dan

I don't see how this is going to work. The Save method in the Excel object is going to be a blocking call, blocking your UI thread(!). So I don't see how you can put up a progress bar and update it while your UI thread is blocked.
|
|
|
|
|
You could use a BackgroundWorker that processes all the information in the background and reports back to your application the progress of the procedure. You would then have a progressbar update with the progress (you might consider a never-ending/repetitive progressbar if you cannot track the time of the save event).

I recorded an actual Macro and it looks like this.
Application.CommandBars("Web").Visible = False
Range("A28").Select
Selection.Hyperlinks(1).Follow NewWindow:=False, AddHistory:=True
Range("A29").Select
ActiveWindow.SmallScroll Down:=3
What I actually have is thousands of rows populated, Three rows are visible with data in the top three rows of my active sheet, 26, 27 & 28 in this example.
When I first open the spreadsheet, I need to make the WEB toolbar go away, this part is good.
I then need to click on the very last hyperlink in 'A' column, I think it may be refered to something like lastused range????? This example is 'A28'.
I then need to put the cursor in the next available empty cell past the lastused range in the 'A' column and post it in the very top left corner, (as though it was in cell A1 ready to work).
This empty cell was in the fourth row so I did three smallscroll to get it to the top row in view.
When I record the macro as you see above it records the actual cell number, this will not help me but I know someone here can please.
I also need the macro to run slowly giving the internet time to upload the hyperlink and then revert back to finish the macro, it just zips right through it now and does not end up in the correct cell when completed.
Thanks in advance for any help, I didnt see a VBA forum, flame suit on.
Lastly, is there a way to make the WEB toolbar stay gone, it wasnt in view by default prior to some MS update I am guessing???

As I have said before I have textboxes bound to the DataGridView. When the user updates a value I have them click on a "Save" button where I get the values that find the row from the current row in the DataGridView and then call Row.BeginEdit, set the values, then call Row.EndEdit.
Only after sorting will the row change event occur (I am verifying this by checking for BindingSource.PositionChanged) and it only happens if I change the value within the sorted column and when it changes rows the row it changes to gets that single changed value.
This is so strange and Im not sure what to do about it.

Let's see the code that's making the changes. Why are you setting the values in the data in code? Why not just bind theTextBox to the fields?

They are bound but I guess Im not sure how to apply those changes except for changing rows.
Dim searchKeys() As String = {value1, value2, value3}
Dim updateRow As DataRow = DsCirculars1.tblAPCirculars.Rows.Find(searchKeys)
Try
With updateRow
.BeginEdit()
.Item("FirstName") = uxFirstName.Text
.Item("LastName") = uxLastName.Text
.Item("Address") = uxAddress.Text
.Item("City") = uxCity.Text
.Item("State") = State.Text
.Item("ZipCode") = uxZipCode.Text
.EndEdit()
End WithThis does work when there is no column sorted and only causes the row to change if I change a value that is within that column.

OK. If the datagrid and the textboxes are both bound to the dataset in the same binding context, you don't need any of this code.
All it takes is something like this:
'
' Code to connect to database and fill a DataTable, or DataSet.
'
' Setup the bindings...
BindingSource1.DataSource = myDataTable
DataGridView1.DataSource = BindingSource1
SomeTextBox1.DataBindings.Add("Text", BindingSource1, "SomeColumnName")
SomeTextBox2.DataBindings.Add("Text", BindingSource1, "SomeColumn")
SomeTextBox3.DataBindings.Add("Text", BindingSource1, "OtherColumnName")
That's it, no other code to set anything really. Unless you're doing something that isn't so straight forward??

Im not doing anything that isnt straight forward but when the user types into the textbox, without moving to another row how is the data refreshed and saved without doing something like I did?

So long as the textbox's are bound in the same binding context, managed by the bindingsource) as the datagrid, you don't have to do anything. It happens automatically!
Try it! Start a new project. Create a form with a DGV and a couple of textboxs on it and add a bindingsource object to the form. Write some SQL to fill a datatable with a few columns of data and bind the BindingSource to the DataTable. Bind the DGV and the TextBox's to the BindingSource, like in my previous post, and try it! It might just surprise you.

I have Edit mode and Add mode, when the user chooses Add mode I clear the textbox bindings and when the user chooses Edit mode I use the following code.
uxFirstName.DataBindings.Add("Text", BindingSourceCirculars, "FirstName", True)
uxLastName.DataBindings.Add("Text", BindingSourceCirculars, "LastName", True)
uxAddress.DataBindings.Add("Text", BindingSourceCirculars, "Address", True)
uxCity.DataBindings.Add("Text", BindingSourceCirculars, "City", True)
uxState.DataBindings.Add("Text", BindingSourceCirculars, "State", True)
uxZipCode.DataBindings.Add("Text", BindingSourceCirculars, "ZipCode", True)
Unless I choose the find the row and edit it, nothing in the DataGridView changes until I change rows in the grid. Am I missing something? Binding seems to be much more complicated in 2.0 than it EVER was in 1.1 and I cant seem to find the information I need in order to make this work the way I want it to.

Is the real trick here to just call BindingSource.EndEdit in order to have that change applied if I am trying to have the user push a "Save" button for familiarity purposes?

Did ya try it?  It's very possible that's all it's going to take. On top of that, maybe refreshing the DGV.

Can someone tell me the difference between these similar dataset writing routines?
The data writing subroutine:
Private Sub New_Bindings(ByVal intOrdinal As Integer, _
ByVal strCode As String, _
ByVal strName As String)
drCurrent = MyDataSet.Tables("tblBindings").NewRow()
drCurrent!Ordinal = intOrdinal
drCurrent!BindingCode = strCode
drCurrent!BindingName = strName
MyDataSet.Tables("tblBindings").Rows.Add(drCurrent)
Call Show_Changes("Sub New_Bindings", MyDataSet)
End Sub
After each row is written into the dataset I have another subroutine that prints out the results called Show_Changes.
Case one – The data is placed directly into the subroutine call.
I’m writing 5 rows to the dataset like this:
Call New_Bindings(1, "TST1", "Record 1")
Call New_Bindings(2, "TST2", "Record 2")
Call New_Bindings(3, "TST3", "Record 3")
Call New_Bindings(4, "TST4", "Record 4")
Call New_Bindings(5, "TST5", "Record 5")
Output screen results after each row addition:
Sub - Sub New_Bindings
TableName: tblBindings
1 TST1 1 Record 1
Sub - Sub New_Bindings
TableName: tblBindings
1 TST1 1 Record 1
2 TST2 2 Record 2
Sub - Sub New_Bindings
TableName: tblBindings
1 TST1 1 Record 1
2 TST2 2 Record 2
3 TST3 3 Record 3
Sub - Sub New_Bindings
TableName: tblBindings
1 TST1 1 Record 1
2 TST2 2 Record 2
3 TST3 3 Record 3
4 TST4 4 Record 4
Sub - Sub New_Bindings
TableName: tblBindings
1 TST1 1 Record 1
2 TST2 2 Record 2
3 TST3 3 Record 3
4 TST4 4 Record 4
5 TST5 5 Record 5
This works just fine. All the records have been written to the dataset and I can use the BindingNavigator control to go from record to record.
Case 2 – The data is placed into the subroutine via variables.
Call New_Bindings(CInt(txtOrdinal.Text), txtBindingCode.Text, txtBindingName.Text)
Output screen after the same five rows are added.
Sub - Sub New_Bindings
TableName: tblBindings
1 TST1 1 Record 1
Sub - Sub New_Bindings
TableName: tblBindings
1 TST2 2
2 TST2 2 Record 2
Sub - Sub New_Bindings
TableName: tblBindings
1 TST3 3
2 TST2 2 Record 2
3 TST3 3 Record 3
Sub - Sub New_Bindings
TableName: tblBindings
1 TST4 4
2 TST2 2 Record 2
3 TST3 3 Record 3
4 TST4 4 Record 4
Sub - Sub New_Bindings
TableName: tblBindings
1 TST5 5
2 TST2 2 Record 2
3 TST3 3 Record 3
4 TST4 4 Record 4
5 TST5 5 Record 5
As you can see the dataset is not the same. The method of data entry is the same except that case 2 uses variables instead of literals. Obviously .NET handles these two similar data entry methods differently, but I haven’t a clue as to how or why this occurs.
Here is the entire code for this one form:

Satips:
I don't know exactly where the application fails. There are two different methods of entering data that should produce the same results, but don't.
Cleako asked for the code on Friday 1 Jun 07 when I first posted it. Today I reposted the question showing exactly what is happening and attached the code at the bottom of the letter so if some one needed the code they could look at it.
Do I need to get with Microsoft for a resolution to this problem?

I asked for the Binding portion, I apologize for not getting back with you. I honestly dont know why you are having an issue with this because it looks correct, it looked correct before, and unless you changed it Im sure it's still correct. What you are doing is one of the most basic functions of ADO.NET.

Thank you for reassuring me I wasn't a dummy  .
I attached the entire form class just in case there was an issue with the data binding portion or something else.
I have one other resource looking it over. If he can't find the problem then I'm being forced to use one of my complementry support intances.
Thank you,

You expect people from the forum to write your code? Perhaps you should try to start to write your own code, then if you run into specific problems ask a question and we will try to help you with your questions.

hi guys
The problem im having is datagridview rowindex matches the binding dataset.table index, as long as I don't click on one of the column headers to change the datagridview sort order. can anyone help me getting rowindex to be the same no matter if i sort the DGV or not.
Thanks in advance
