How to copy new data from server to a local database.

Can somebody tell me what is the easiest way to copy new data from MySQL database placed on server to a local Access 2003 DB on my computer? (Using Visual Basic 2005 PRO)

I want to copy whole rows (about 25 columns: strings, doubles, booleans and one BLOB).

Thanks

you need two connections that return two datatables once you have your datatables you can do something like this If the table schemas are the same :

MyAccessDT.Merge(MySQLDT)

How to convert text in GridView col into a hyperlink?

Hi,

One of the fields in a GridView control contains a unc path to a local area network folder [eg:\\servername\foldername].

Each record in the GridView may have a path to a different folder.

I would like to be able to click on the path in the GridView and have the folder open - instead of having to copy the text into the Start | Run dialog box of my pc.

I've looked at converting the column into a hyperlink control [by making it a Templated control] & I've tried this code:

<Columns>
<asp:hyperlinkfield datatextfield="Path"
datanavigateurlformatstring="Path"/>
<asp:BoundField DataField="Path"
HeaderText="Online"
SortExpression="Path" />
</Columns>

. . . and I get an error because the app is trying to open a folder in the directory where the web site resides rather than the folder that is indicated in the path [Text] in the column.

I'm trying to figure out how to tell asp.net to open the folder indicated by the unc path in the field . . .Confused

I'd appreciate any help I can get.

Thanks!

Robin

What most likely is happening, is all links in a website by default are relative, so you end up with a link to something like this

http://localhost:12345:\\servername\path

Which obviously isnt going to work. You can fix it by prefixing it with something it recognizes as a file path, rather than a relative path.


Try replacing your <asp:HyperLink /> with this:

<Columns>

<asp:TemplateField>

<ItemTemplate>

<asp:HyperLinkText="TextField"id="myHL"runat="server"

NavigateUrl='<%# "file:///" + DataBinder.Eval(Container.DataItem, "Path").ToString() %>'></asp:HyperLink>

</ItemTemplate>

</asp:TemplateField>

</Columns>

Thanks, Hans! That worked.

I have one more question, though. In the Text = "TextField" - I would like the text that displays be the actual path that is coming in from the database.

So - instead of TextField [hard-coded literal] in the GridView I'd like it to have something like this -\\ServerName\FolderName [what is in the field for each record].

How would I do that?

Robin


Text='<%# Databinder.Eval(Container.DataITem, "Path").tostring() %>'


Thanks, Bryan. Perfect! I tried playing around with that line of code from Hans . . .
