I am working in vb2008. Is there a simple way to clone the contents of a datarow in a datatable into a new datarow instance that can be added elsewhere in the table. Can I create a new instance of a datarow and set it equal to an existing datarow?
View 5 RepliesSee the code below which is triggered on a datagridview row validation event where the datagridview datasource is a datatable.
The messagebox shows that it loops around as expected populating the datarow with the expected values (NOTE: There are no primary keys as this is a college assignment with specific requirement and all fields can be nullable).
I had to use ImportRows as AddRows would always error due to "This row belongs to another table" the odd thing was the values were different and again the table contains no primary keys.
The code below runs but never adds a datarow to the dataset datatable "Bookings", does anyone know what the problem might be?
CODE:
I'm trying to delete the selected row in a gridview from the datatable but it seems like it's not deleting. in if statment Table.Rows.Count = 0 is not working and I'm trying this with one row in the grid view.
Protected Sub GridView1_RowCommand(sender As Object, e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles GridView1.RowCommand
Dim index As Integer = Convert.ToInt32(e.CommandArgument)

I have a listbox and its source is a DataTable, when i click a button i want to get the selected datarow somehow, maybe the index number of it so i can edit its values etc.

This is bug in VB 2008

Table has Two Fields (ExprID, Expression)

The Problem is, When i becomes 2, Table Data also becomes "q", Why....?
I have created a datatable and now i need to print it,so i did the following:
Private Sub PrintDocument1_PrintPage(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage
Dim xPos As Single = 20
[CODE]...
The code works fine.But in the above code as you can see that i am printing the each rows content of the datatable one by one and after printing all the contents of a single row i am looping the code again for printing each and every row present in the datatable. So i want to know that inspite of printing each and every data present in the row of the datatable,is it possible to print the entire datarow at a time and then loop through all the rows present in the datatable?
I have a datatable with 2 columns named TimeStamp and value. After I populate the table with rows, I am using the table's compute method to get the max value like this....
MyTable.Compute("MAX(value)", Nothing)
Is there is a way to get the row (or more specifically the TimeStamp value) where the max was found?
I have two datatables with similar structures that I want to make one existing row to be updated from another datatable.
For example, "tableA" has three columns: "one", "two", and "three"; with "one" being the primary key...
and "tableB" has three columns as well: "one", "two", and "three"; with "one" being the primary key.
Say there is a row on tableA that is different than a row on tableB (with a matching primary key). What I wanted to do, as efficiently as possible, is to take the that row from tableB and replace the one on tableA so it'll be modified.
I'm not sure if there's an easier way of doing that instead of using loops for setting the row's items.

View 1 RepliesI've got a VSTO3 Word addin that makes use of custom ribbons and taskbars, etc.
Now, Office 2010 comes along and there's this nifty new BACKSTAGE concept, which I'd like to hook into. However, from what I can tell, doing it with VSTO requires Vsto 4, which requires VS2010, which isn't an option.
Soooo. I started looking online and have found all sorts of examples of, essentially, piggybacking the backstage XML onto whatever Ribbon xml I define and returning that as the value of GetCustomUI. All good, except if you're using VSTO3, there doesn't appear to be any way to "hook" into the call chain for GetCustomUI. It's all "automagically" handled for you by the OfficeRibbon and RibbonManage classes.
I know I +COULD+ convert the addin to a shared addin and just implement the IDTExtensibility interfaces directly. I'd lose all the vsto goodness (yeah, that's debatable) but I'd gain access to the GetCustomUI call.
Anyone every tried to get access to GetCustomUI +WHILE+ using VSTO though? Is it even possible?
I thought I could create a wrapper class for RibbonManager, but lo, MS has gone and done what looks to be some supreme violation of encapsulation. The RibbonManager implements the nice and easy IRibbonExtensibility interface, and yet, where that interface is passed around, they actually check the passed object to be sure it's of the actual type RibbonManager! Ugh, so much for any kind of wrapper.

How To Design an Outlook AddIn to capture New Mail Event In Vb .net. I've been able to use code to read the number of unread email messages in an Outlook Inbox. I'm trying to design a plug-in which will be more functional and Catch whenever the SendReceive event is fired. Can anyone point me in the right direction?
I am writing an outlook addin that is supposed to check for any new email messages. I am trying to attach to the send/receive action that occurs within Outlook (Either auto S/R or manual S/R). I have read on a forum online that there is no such event as a Send'Receive, how ever you can use a NewMailEvent. Can anyone demonstrate how this could be done in VB 2005/2008?

I wrote a C# Excel automation addin (Excel 2010 64bit, VS 2010) to provide some additional user-defined-functions in Excel. Now, the addin works fine besides the fact that the two methods "OnDisconnection" and "OnBeginShutDown". are not called when I close Excel which is a problem for me. Also, while Excel seems to shut down properly, the instance is still running in the background after the excel-window has disappeared. So, apperently the problem is that Excel is not shut down properly.

View 8 RepliesI currently need to build a Automation Add-in for Excel. This add-in will load a recordset from Database to Excel. I would like to have function A() that I input in Cell as a formular. This function A() call a the add-in to load the data from Database to Excel. The data should be a matrix. So that means I would like to set in Excel worksheet a range of data by just calling single function in a cell. (I am sure there should be some way to implement it)As I know if I develop a shared Add-in by VB(or VB.Net) and in the add-in, I can get an Object of Excel.Application. By this Excel.Application object, I can get full control of Excel inside the Add-in. That means if I define a sub that load datamatrix from database and using the Excel.Application object I can populate the data matrix to the Excel.
I have done much research on internet and I now have built a shared Add-in for excel. I should say this add-in works fine without invoke the Excel.Application Object that I have tested. But when I call the Add-in function that invode Excel.Application Object from Excel I got an error as below:

View 2 RepliesI have a VB.NET project in Visual Studio 2008 that I created a specialized addin for. The addin prompts the user to select a database table, takes a template form class's files, copies them to another directory within the project, and renames the form class within the copied files. It then opens the new form and adds controls to it based on the fields in the database table.
The copying of the template form causes the background compiler to give 'duplicate member' errors, such as "Private Sub InitializeComponents(...) has multiple definitions with identical signatures," even though I renamed the files of the new form and the class name within them. Sometimes these errors go away before the new form is opened, but when they stick around the new form doesn't open correctly, and it throws an error instead. I implemented some code to wait until there are zero errors in the error list before trying to open the new form. This has helped sometimes, but for some reason sometimes the errors don't go away at all until the addin is closed.
How to copy the template form and rename the copy without the background compiler ever noticing duplicate members. If that's not possible, then perhaps someone has an alternative?
Here is my code that copies and renames the template form:
Private Sub CreateDataForm(ByVal tableName As String, ByVal displayName As String) ', ByVal subDataForms As IList(Of Object))
Try
Dim dataFormClassName As String = "frm" & MakeValidName(displayName)
Dim dataFormFileName As String = dataFormClassName & cVBSuffix
