I think having .NET skills and Java skills covers a lot of bases. Add some real experience with web application development (including client-side scripting) and solid experience with relational database design/development and you're in very good shape.
What do you enjoy doing? Do you like database programming? web programming? building desktop applications? lower level programming for, say, device drivers? does a particular business appeal to you, such that marrying your technical skills to specific business processes is appealing?
I'm not surprised that you would get so many different suggestions for what skills would "have the brightest future ahead". What you enjoy doing is what would give you the brightest future.

I want to pass the value of the selected item in a dropdownlist to a label. The dropdownlist is inside a FormView and
the label is outside in the main form. I'm trying to do this by implementing an event handler for the event
OnSelectedIndexChanged.
I cannot get it to work as I get an error:
Object reference not set to an instance of an object w.r.t code: Label1.Text = myDDL.SelectedItem.Value.ToString();
Here's the ASP/HTML
...
<asp:formview>
....
<insertitemtemplate>
....
<asp:dropdownlist id="DropDownList1" runat="server" datasourceid="SqlDataSource1"
datatextfield="StaffID" datavaluefield="StaffID" selectedvalue="<%# Bind("StaffID") %>" autopostback="True" onselectedindexchanged="DropDownList1_SelectedIndexChanged" ondatabound="DropDownList1_DataBound">
....
....
<
<asp:sqldatasource id="SqlDataSource1" runat="server"
connectionstring="<%$ ConnectionStrings:MyConnectionString %>"
selectcommand="SELECT StaffID FROM Staff_tbl">
...
<asp:label id="Label1" runat="server" text="Label">
Here's the event handler (c#)
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
DropDownList myDropDownList = (DropDownList)FindControl("DropDownList1");
Label1.Text = myDropDownList.SelectedItem.Value.ToString();
}
My FindControl clearly isn't doing what I think it should.
I can get this to work if the dropdownlist is not inside a FormView where there is no need to use FindControl.
E.g.
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
Label1.Text = DropDownList1.SelectedItem.Value.ToString();
}
But unfortunately I NEED to have the dropdownlist inside a FormView.
Thanks

Your drop down list will be rendered on the client with a name like FormViewName_DropDownList1.
|
|
|
|

Thanks - I had omitted to specify the container (FormView1). Was
DropDownList myDropDownList = (DropDownList)FindControl("DropDownList1");
but should have been
DropDownList myDropDownList = (DropDownList)FormView1.FindControl("DropDownList1");
Many thanks

How about something like this?
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
DropDownList myDropDownList = (sender as DropDownList);
if (myDropDownList != null)
Label1.Text = myDropDownList.SelectedItem.Value.ToString();
}

I have just installed the .NET Framework 1.1 on my machine. But the web application I was developing can no longer access the database I have. I keep getting the error.....
System.Data.OleDb.OleDbException: Unspecified error
Now I know it has something or other to do with permissions. And Have been messing around with every option I can find but still it doesn't want to access it.
Another strage thing it is doing, is I have a number of different .jpgs for the different webforms. And because when I upload it to my webhost it doesn't recognise the file path c:\webapplication....etc etc I simply store all the .jpgs in the root folders and just access it by Image1.jpg instead of having a path name. Right now one of my webforms beckground is blank, if I change it to Image4.Jpg it shows up, if I change it back to Image5.jpg it goes blank again, despite both files being in the root folder.
Any help would be appreciated.

It's ok I found and fixed the problem. For reference the problem was....
In the .NET Framework 1.0, ASP.NET applications use the TEMP folder that is designated by the environment variables to store temporary files. In .NET Framework 1.1, ASP.NET applications use the profile folder for the local ASPNET account to write temporary files. This profile folder is C:\Documents and Settings\ServerName\ASPNET\TEMP. The ASPNET account has permissions to write to this folder.

Hi all
I already posted something similar but i ll be morz accurate now. I want to download a file from my web server from a remote computer. I heard it might possible to use a hyperlink and then to do a right click + Save As so the user can chose the directory where he wants to save the file. But i don t know how to do that so i ask if someone can help me with my prob.
Thx a lot

just point the href of your hyperlink to the document on your server's file system.

I am calling API of our own through dot net code to create a pdf file.After 1016 files created during report generation it's stop creating pdf files. I thing it is all because of Memory Leak. How do i force garbage colleter to release memory. I am using gc.collect() after that gc.gettotalmeory(true). How i reduces the cpu utilization it's show 100 %.
Can any one help me ?
Thanks in advance

I'm guessing the API to which you're referring is your own in-house COM object? If the memory leak is in the COM object, the .NET garbage collection won't help you, as it's not managed code.

How do i find out memory leak in my code. If it is in API how do i find it?
