Hi,
If I want to save an uploaded file to subfolderX I can use this:
objFile.SaveAs(Server.MapPath("subfolderX\" & savedFilename))
OK, no problems. But now I want to check that subfolderX exists, and create it if it doesn't. So I do this:
If Not System.IO.Directory.Exists(Server.MapPath("subfolderX")) Then
System.IO.Directory.CreateDirectory(Server.MapPath("subfolderX"))
End If
OK, no problem. This works.. on my local machine. When I try it on my ISP's server I get an error: "Could not find a part of the path e:"
When I contacted them they suggested I try hard-coding the fully qualified network path instead:
If Not System.IO.Directory.Exists("\\iisX\domains\x\....\subfolderX") Then
System.IO.Directory.CreateDirectory("\\iisX\domains\x\...\subfolderX")
End If
This works - but why doesn't Server.MapPath, esp given that it DOES work for saving files??!! This doesn't make sense to me...
I don't want to use the hard-coded version if possible, as it doesn't lend itself well to the application's portability.
Any deas, anyone...?
thanks
Phil

Try printing out what path the Server.MapPath() method returns, and see if this helps.
The reason the createdirectory doesn't work seems to have to do with the fact that your application is hosted on a different machine internally in the hosting company, since you have to give them the full networkpath.
How about it if you try with the Tilde "~" character (implying the current application)?
Server.MapPath("~/subfolderX")
Kind regards - Jakob

I have - it gives "e:\...." (etc)

Same as above.

Weel, yes... but why then does
objFile.SaveAs(Server.MapPath("subfolderX\" & savedFilename))
work fine but
System.IO.Directory.CreateDirectory(Server.MapPath("subfolderX"))
not? That's the really puzzling thing.
thanks

I dont think anyone other than your hosting comany could possibly give you a definitive 100% accurate answer - but the chance of finding and speaking to a programmer there that understands such matters is slim!.
I can tell you that Server.MapPath works better the more of the path it has to go on. So, in your case you say that this works:
objFile.SaveAs(Server.MapPath("subfolderX\" & savedFilename))
so you are giving it quite alot to go on
Server.MapPath("subfolderX\myfilename.ext")
the one you say does not work has less to go on
Server.MapPath("subfolderX")
if you know the folder above subfolderx, you might try prepending that to give MapPath more of a hint, but I cant guarantee that will make any difference whatsoever.

Thanks - but didn't help.
This is so odd - the line that checks if the folder exists works:
If Not System.IO.Directory.Exists(Server.MapPath("subfolderX")) Then
because if I replace subfolderX with one that does already exist then it returns true; but if subfolderX doesn't then
System.IO.Directory.CreateDirectory(Server.MapPath("subfolderX"))
fails with a "Cannot find part of path" error. As I can create folders by hard-coding the network path I assume it isn't a permissions thing. (Unless there are different permissions to creating network folders from virtual ones..? Never have understood this side of things...) And saving files works.

Indeed....!
Oh well... thanks for trying folks

Hello There
There is a search form in my scenario in which user will fetch say 100 records in one go. and then he has button "Next 100". Now I am adding the next button dynamically . but the addhandler is not working.
Can any one help me how to make sure that handler should work. The code is
' I have a server side table in which I am adding rows and cells
Dim cellBtnPrevious As New System.Web.UI.WebControls.TableCell
Dim btnRow As New System.Web.UI.WebControls.TableRow
Dim BtnPrevious As New System.Web.UI.WebControls.Button
Dim BtnNext As New System.Web.UI.WebControls.Button
Dim BtnWidth As New System.Web.UI.WebControls.Unit(100)
BtnPrevious.Width = BtnWidth
btnNext.Width = BtnWidth
BtnPrevious.Text = "Previous"
BtnNext.Text = "Next"
AddHandler BtnNext.Click, AddressOf NextRecords
AddHandler BtnPrevious.Click, AddressOf PreviousRecords
cellBtnNext.Controls.Add(BtnNext)
cellBtnPrevious.Controls.Add(BtnPrevious)
btnRow.Cells.Add(cellBtnNext)
btnRow.Cells.Add(cellBtnPrevious)
tblContents.Controls.Add(btnRow)
'' The definition of one function is
Private Sub NextRecords(ByVal sender As System.Object, ByVal e As System.EventArgs)
'' code here
end sub
Thanks

I am defining relationship between datatables by using oracle as the backend.
It works fine in sql but in oracle it prompts an error "OBJECT REFERENCE NOT SET TO AN INSTANCE OF AN OBJECT"
my code for SQL is

Dim adapter1 As New SqlDataAdapter(str1, conn1)
adapter1.Fill(ds1, "categories")
adapter1.SelectCommand = New SqlCommand(str2, conn1)
adapter1.Fill(ds1, "products")
ds1.Relations.Add("categories_products", ds1.Tables("categories").Columns("categoryID"), ds1.Tables("products").Columns("categoryid"))
Dim categories As DataTable = ds1.Tables("categories")
DataGrid1.DataSource = ds1.Tables("categories")
DataGrid1.DataBind()
DataGrid2.DataSource = ds1.Tables("categories.categories_products")
DataGrid2.DataBind()

If it is a server control then you set the text like this:
YourButtonName.Text = "whatever";
if it is a HTML input tag then you set the value attribute.

http://livedemos.peterkellner.net/AJAXDemo/
anyone has any ida how i can start on this?
I downloaded MembershipEditorAtlas1.zip and used asp.net configuration to configure it.
But it keeps giving the error
The type specified in the TypeName property of ObjectDataSource 'ObjectDataSourceMembershipUser' could not be found.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Anyone has any idea... i really urgently need to get this to work... thanz

There are a couple things which you might want to check:
+ Where is the type specified in the TypeName property defined? (In the App_Code folder or in a seperate assembly)
+ Check the assembly reference if any.
+ Check if the type name in the TypeName property is qualified or not?

Gave up on earlier post of using imageButtons and command arguements, but can't get the following to work either. When trying to delete a row, and using the SELECT rows, I get an error of the selected index out of range even though I'm asking it to select the record in the dataset based on a primary key field (the rows commented out). When using the FIND rows, it stops on the row.delete() line with an error of "Object reference not set to an instance of an object." Really frustrated and would appreciate some help.

I have two pages A and B.
ON page A, I have three drop down boxes ( month , year, and unit_abbr and they have cascading and Auto post backs) and click button to run a report. What I am trying to do is keeping selected drop down list values after the postbacks. The problem right now is when I come back to page A after I browse page B , the selected values in dropdown boxes are set back to the default ( in my case most recent month, year, unit_num). How can I keep the selected values inside of dropdown lists while I am browsing around different pages? If I select month = 1 year 2006 unit_abbr = D11 to run the report on page A, then go to the different page to browse around different report and when I come back to Page A, the selected parameters in those drop down lists should be set to month = 1 year 2006 unit_abbr = D11
Here is my code using session variable:
<asp:label id="Label4" runat="server" text="Select Year:" forecolor="Black" font-bold="True" font-names="Arial" font-size="8pt">
<asp:dropdownlist id="DropDownList2" runat="server" datasourceid="SqlDataSource3" datatextfield="year" datavaluefield="year" font-names="Tahoma" font-size="8pt" autopostback="True" onselectedindexchanged="DropDownList2_SelectedIndexChanged1">
<asp:label id="AccountStatus" runat="server" font-size="16pt" visible="False" width="87px">
<asp:label id="Label5" runat="server" text="Select Month:" forecolor="Black" font-bold="True" font-names="Arial" font-size="8pt">
<asp:dropdownlist id="DropDownList1" runat="server" datasourceid="SqlDataSource2" datatextfield="month" datavaluefield="month" font-names="Tahoma" font-size="8pt" onselectedindexchanged="DropDownList1_SelectedIndexChanged" autopostback="True">
<asp:label id="Label7" runat="server" text="Select Region:" forecolor="Black" font-bold="True" font-names="Arial" font-size="8pt">
<asp:dropdownlist id="DropDownList4" runat="server" autopostback="True" datasourceid="SqlDataSource6" datatextfield="region_name" datavaluefield="Region_num" font-names="Tahoma" font-size="8pt" onselectedindexchanged="DropDownList4_SelectedIndexChanged">
--Here is code behind
public
partial class Dashboard : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack && ((this.Session["MMselectedvalue"] != null) && (this.Session["YYselectedvalue"] != null)
if (!Page.IsPostBack && ((this.Session["MMselectedvalue"] != null) && (this.Session["YYselectedvalue"] != null) && (this.Session["Unitselectedvalue"]) != null) && (this.Session["Regionselectedvalue"] != null))
{
this.DropDownList1.SelectedIndex = Convert.ToInt32(this.Session["MMselectedvalue"]);
this.DropDownList2.SelectedIndex = Convert.ToInt32(this.Session["YYselectedvalue"]);
this.DropDownList3.SelectedIndex = Convert.ToInt32(this.Session["Unitselectedvalue"]);
this.DropDownList4.SelectedIndex = Convert.ToInt32(this.Session["Regionselectedvalue"]);
GridView4.DataBind();
}
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
this.Session["MMselectedvalue"] = this.DropDownList1.SelectedIndex;
}
protected void DropDownList2_SelectedIndexChanged(object sender, EventArgs e)
{
this.Session["YYselectedvalue"] = this.DropDownList2.SelectedIndex;
}
protected void DropDownList3_SelectedIndexChanged(object sender, EventArgs e)
{
this.Session["Unitselectedvalue"] = this.DropDownList3.SelectedIndex;
protected void DropDownList4_SelectedIndexChanged(object sender, EventArgs e)
{
this.Session["Regionselectedvalue"] = this.DropDownList4.SelectedIndex;
But, the problem is the data controls of drop downboxe ( sql datasource) are overwriting the session varialbles, so it set back to the default value...
How can I keep the session variables after the data binding ( sql datasource for drop downboxes)? ,and How can I ditermine whether it's just a postback ( changing selected values on the same page) or the user is actually changing the page( navigate different pages and come back to the same page).?
