Delete Or Unload Current PDF From Reader Plugin In WebBrowser?
Nov 25, 2009Background: I am creating PDF with PrinceXML.I want to adjust the tracking on a paragraph in the PDF. So I select a unique piece of text, match it in the starting document, add a tracking attribute to the text, and re-create the PDF using PrinceXML.I have to delete the current PDF in order to create the revised PDF.When I was using the AxAcroPDF1 control in VB.NET all I needed to do was
1) If File.Exists(sPDFoutputName) Then File.Delete(sPDFoutputName)
Now I am trying to do the same thing but instead of using the AxAcroPDF control I am trying to do it with WebBrowser [Why am I doing this? Adobe places a burden on the developer to maintain a list of who has the program (Reader) to comply with US export law. This is an unacceptable requirement for the program.]
2)WebBrowser1.Navigate(sPDFoutputName + "#" + sPDFargument)
I want to jump to the same page that I was on so set the page to open in the sPDFarguement variable.Now when my program tries to delete as in #1 above I get error message that file is locked/in use.Question: How do I unload/close/unlock file in the webbrowser so I can delete it?The closest idea that I have found that almost works is to copy the xxxPDF to another file: displayPDF and only display the latter.With this I can delete and recreate a new xxxPDF. The problem again hits me when I try to delete the displayPDF. I have also tried to navigate to a dummyPDF but still displayPDF remains locked.

View 1 RepliesUpdating The Current Record On The DataGridView?
Jun 22, 2011Visual basic 2010. I am having a problem with updating on a DataGridView that has me confused.
I have a DataGridView on the first tab page that is displaying data in a DataTable.
On the second tab I am updating the current record on the DataGridView.
The text fields on the second tab are bound to the DataTable in the following manner
rnameTxt.DataBindings.Add(New Binding("Text", TableData, "rname", True))
When I move to the second tab the correct data appears in the text fields.
When I modify a field on the second tab the modified data appears in the DataGridView, on the first tab page. But when I check for changes in the DataTable in the following manner
Dim ModifiedRows As DataTable = TableData.GetChanges() I do not see the modified row - i.e. ModifiedRows = Nothing? Why is the modification not being identified???

So this is what needs to happens if the focus is on the DataGridView when the user hits the Tab key it moves the focus to first text box.

DB/Reporting :: Bind These Textboxes With Current Datagridview Position?
Apr 10, 2008On one of my forms i have a datagridview binded to an Access database. It displays only first and last names of my customers in a datagridview.What i want to do now is, when i double-click on one of the customers another form will open and display details for this customer (detailed view - textboxes).
What i have accomplished so far is that when i double-click on a customer in datagridview a form opens with details (linked to the same binding source as datagridview). But the problem is that it always opens the first record even if i dobule-click second or third in datagridview.I don't know how to bind these textboxes with current datagridview position?

IDE :: Add Data From DataGridView To Database When The Current Row Lost Its Focus?
Oct 3, 2009I have a small doubt: (VB.Net 2005, MS-Access 2007)Is it possible to add the current row from DGV to DB as soon as the row lost its focus..i.e. whenever i add a new row in DataGridView it should automatically get inserted into the database without pressing any buttons... Bcoz i need to add more new rows dynamically & hence i find little difficult in clicking the ADD button again and again to insert each and every Record.

View 3 RepliesDatagridview - When User Switches Around Columns It Won't Print In Current Order
Oct 27, 2011When user clicks on a button on my form, it sends the datagridview on that form to another class that [basically] does a bunch of stuff and shows a dialog with a print preview. Everything works perfectly fine, except that if a user switches around columns it won't print them in that current order. For example, if user moves the LastName column before FirstName column, then it should print in that order, but it prints in the column order that the datagridview was originally loaded. The dgv1, is the datagridview that was originally loaded, not the current one. [Code]

Row Delete From DataGridView?
Nov 23, 2009I'm new to VB and using a datagridview for the first time. I've spent the last 2-3 days trying to get row deletion to work and can't do it. I've tried every piece of code I can find on the internets, and none of them are doing it.I have the selection mode set for full row, with a delete button on the form. Clicking it will delete the row from the DGV, but the changes are not going back to the database. Here is the code I'm using right now in my delete button event handler:

The row disappears from the DGV, but not from the database. I've gone back and started from scratch a few times now
