In Net 2.0 you can use System.Security.AccessControl namespace for various options but in .Net 1.1 the only option is using P/Invoke

Dear sir:
I have written one test page for up-loading the large file.

上传
In my HttpModule, I call the function

But I cann't get the correct pointer. Null is returned from this function.
I donn't know the reason, Do you know this reason?
Thanks!:

Hi,
I have designed some programs on SWT and Swing using Java. There are many similar features that both c# and java have. When programming with Java I was using just one window(form) and than embed a necessary panel to it. Panels are designed seperately and named differently. For example one panel named SavePanel.java is used to save an entry(think about an address book). When the saving process is done, other panel named SearchPanel.java is called to the window. So when the user presses a button, a panel that is related to that process is called to the form.
In C# I can't find any feature like this. When I create a panel, I cannot add buttons or textboxes to them. The visual editor cannot show them.
I don't want to design one form for saving and one form for searching. Just one form is enough. According to the process that user wants some part of the form will be change. And changing part have to be designed easily using visual editor.
If any of you made something like this before, or any idea similar to this problem, please help me. Any articles, documents or related websites will be helpful.
Thanks

You have to add and remove UserControls to your main Form. A UserControl for Save and one for Search. Depending on what to do, add either of them to the Form.
UserControls can be designed with the Designer (Editor).

There is more than one way to attempt to solve this problem but I would encourage you to log a little time with the Mutex class.
Have fun,

Each time the event fires, you are creating a new DataTable object, adding a row to it and binding it to your control. This means that you are discarding any data that you had previously bound to the control. If you want to append your new row of data to the data you have already created you should replace
DataTable dt= new DataTable();
with...
DataTable dt = null;
if (gdvDistributorSlab.DataSource == null)
{
dt= new DataTable;
}
else
{
dt = (DataTable)gdvDistributorSlab.DataSource;
}

I have two forms. Form1 with a listbox (with 3 items) and a button. When this button is clicked form2 should open. On Form2 there is a tabcontrol with 4 tabpages. When Form2 loads I want it to show with just 3 tab pages. So on Form1 i have the following variable defined:
public int countItems
{
get { return listBox1.Items.Count; }
}
On form2 I have made form1 public ( public Form1 frm1; ) and in the form2 load event i have the following:
if (frm1.countItems == 3)
{
tabControl1.TabPages.Remove(tabPage4);
}
This complies with no errors but when the application is run and the button is clicked to bring up form2, the following error appeas for the line if (frm1.countItems == 3):
Additional information: Object reference not set to an instance of an object.
Can anyone tell me where I am going wrong?

hi
set the count-value in the form2 constructor e.g.
Form2 form2 = new Form2(listBox1.Items.Count);
form2.Show();
in the constructor of form2 remove your tabpage.

Do we need to do anything regarding session management or it is automatic? If I am using IIS server. I run the script called Installsqlstate.sql and two table created in the tempdb.
Be Well

First a link to MSDN that you should take a look at:
ASP.NET State
Sesion Management is automatic and you can use the Session property on the Page to access the Session-local data.

If you're using IIS, then the session ID is created for you automatically.

Can anyone tell me if the following can be done directly in .net without having to delve into p/invoke?
- The drive Z:\ can be mapped to C:\blah\ or c:\wibble\
- I have a load of filenames in the form C:\ paths
- I need to filter out the ones that correspond to the current Z:\ mapping (e.g. I need to ask the system where Z:\ is pointed, and string compare the filenames with the given path)
Can anyone help? (I just need the bit that tells me the location of a subst'ed drive.)
Cheers,
benjymous
