Hi,
I am using below code to delete a file from my application which works fine for some folders. When I try to delete file from system folders such as \program files\.. or windows\... folder i get access denied. What are the changes required so that whenever user tries to delete file from system folder, vista will show security popup which asks administration password which it normally does for system folders.
Here is the code..
if (File.Exists(Path.Combine(tstxUrl.Text, lvItm.Text)))
{
File.Delete(Path.Combine(tstxUrl.Text, lvItm.Text));
}
Thanks

He has to have administrator privileges. How much more clear could Vista be about that?

As John said you need to give your program administrator rights to do this.
This can be done in vs2008 by setting the UAC settings in your project settings (application tab, 'view uac settings' button).
This will however have the effect that every time the user starts the program vista will ask the user if he is sure that he wants to start the program since it requires administrator rights.
But why would you want to give the user the possibility to delete files in these folders? They are protected for a reason.

Thank you for your valuable help

Actually my application is similar to windows explorer, a file management tool, hence i required this functionality.

I am writing a database application using Csharp. The database can be access, sql server whatever.
I have 100 variables in one database table. The variable names are V1, V2,V3,...,V100.
I put 100 textBox controls on one Form. I hope users input data through these textBoxes.
the codes look like:
V1=textBox1.text;
V2=textBox2.text;
V3=textBox3.text;
....
V100=textBox100.text;
This is just too tedious.
I want to do this way:
Make a 100 elements array V[i], and use a for loop;
for(int i=0;i<100;i++)
{
V[i]=textBox[i].text;
}
I can do this in SAS program using Marco variable.I am wondering if I can do this in csharp.
Thanks.

for (int i=1; (i <= 100); i++) {
TextBox t = getControlByName (String.Format ("textBox{0}", i)) as TextBox;
if (t != null)
V[i] = t.Text;
}For an example of getControlByName() see this[^] article.

Thank you Ravi, would you like to change the vb.net function to a csharp function?

private void CreateTextBoxes()
{
for (int counter = 0; counter <= NumberOfControls; counter++)
{
TextBox tb = new TextBox();
tb.Width = 250;
tb.Height = 60;
tb.TextMode = TextBoxMode.MultiLine;
tb.ID = "TextBoxID" + (counter + 1).ToString();
// add some dummy data to textboxes
tb.Text = "This is textbox " + counter + " data";
phTextBoxes.Controls.Add(tb);
phTextBoxes.Controls.Add(new LiteralControl("
"));
}
}
In CreateTextBoxes method I loop through ‘n’ numbers of controls that we wants to create dynamically in phTextBoxes placeholder.
// Add DropDownList Control to Placeholder
private void CreateDropDownBoxes(DataTable dtTable)
{
for (int counter = 0; counter <= NumberOfControls; counter++)
{
DropDownList ddl = new DropDownList();
ddl.ID = "DropDownListID" + (counter + 1).ToString();
int nTotalRecords = dtTable.Rows.Count;
for (int i = 0; i < nTotalRecords; i++)
{
ddl.Items.Add(dtTable.Rows[i]["item"].ToString());
}
phDropDownLists.Controls.Add(ddl);
phDropDownLists.Controls.Add(new LiteralControl("
"));
}
}
In CreateDropDownBoxes method I have done the same thing by looping through ‘n’ numbers of controls, the value of ‘n’ which was stored in ViewState, and create them in a phDropDownLists placeholder control.
// Create TextBoxes and DropDownList data here on PostBack.
protected override void CreateChildControls()
{
// Here we are recreating controls to persist the ViewState on every post back
if(Page.IsPostBack)
{
CreateTextBoxes();
InitializeDropDownBoxes();
}
// Create these conrols when asp.net page is created
else
{
CreateTextBoxes();
InitializeDropDownBoxes();
// Increase the control value to 1
this.NumberOfControls = 1;
}
}
CreateChildControls method, here we are recreating control on every PostBack. If the page is created the first time we just create these controls and save 1 in the ViewState so we know that we have created these controls and assigned the controls id to 1.
// Increase the counter when button is clicked and add to view state
private void btnAnotherRequest_Click(object sender, System.EventArgs e)
{
NumberOfControls += 1;
}
In button event handler we just increase the counter by 1, and save its value to ViewState for later retrieval.
Once we have created these controls on ASP.NET page, retrieving data from these dynamically created controls is easy by using FindControl method.
// Read DropDownList Data
private void ReadDropDownLists()
{
int n = this.NumberOfControls;
for (int i = 0; i<n;>{
string DropDownListName = "DropDownListID" + (i+1).ToString();
DropDownList ddl = phDropDownLists.FindControl(DropDownListName) as DropDownList;
lTextData.Text += ddl.SelectedValue + "
";
}
}
And
// Read TextBoxes Data
private void ReadTextBoxes()
{
int n = this.NumberOfControls;
for (int i = 0; i<n;>{
string boxName = "TextBoxID" + (i+1).ToString();
TextBox tb = phTextBoxes.FindControl(boxName) as TextBox;
lTextData.Text += tb.Text + ("
");
}
}

Hi
I am using C# and Visual Studio 2005 to develop a Windows Application. I use the designer to bind a DataGridView to a table in a MS Access database.
When I use the designer the following code is automatically generated in the Form_Load method:
this.procPatientList_AllInfoTableAdapter.Fill(this.patientStatusDataSet.procPatientList_AllInfo);
I try to update the database when changes have been made to the data in the DataGridView, but cannot find what to use or how to do it. In the past I used to write my own code and could do updates. I am trying now to learn about the built-in functionality, but I am struggling.
Neither procPatientList_AllInfoTableAdapter nor patientStatusDataSet has any Update methods.
Any assistance will be appreciated.
Thanks.

Dave Kreskowiak(CodeProject) tought me to Stop using wizards when am doing my Daatabase work.
wizards have limitation and its not easy to debug if you did not write the code for yourself. i suggest you start writting your data layer so that you can see what is the Problem. as you said you use to write the code your self, why did you stop because its the best way of doing things, i have an Article that can get you started on how to update a Datagrid.

You have to create a third Image painting both of your source images into this new image, then you can set the PictureBox to this third image.
No, I can't write the code for you. I simply don't have the time right now.

Been a while since I worked with this but from what I remember you can pas a printersettings and a pagesettings object with the report.open method.
See if that helps you.

Thankyou very much for your suggestion. But please explain me with a sample.
THank you again

As I said in my original reply it's been a while so I don't know the exact code.
But normally you should have an instance of your report
and that instance should have a open method in which you can pass the objects pagesettings and printersettings

Dear all,
I'm trying to get my computer to listen on a port and pass on the received data ( after some modification ) over Multicast. I'm receiving data on the socket every second. I wrote the code below and it works perfect.
The problem that I require some assistance with is pretty simply. Everytime a string of data is received, the socket is closed and new socket is opened to wait for the next string. When the next string of data comes in, it gets processed and the socket is closed again. This means that after a period of time, lots of socket connections are made. One of them is active and the others are in a TIME_WAIT state ( and that list keeps growing ) Is there a way around this ?
Int32 port = 31008;
IPAddress localAddr = IPAddress.Any;
server = new TcpListener(localAddr, port);
server.Start();
Byte[] bytes = new Byte[256];
String data = null;
while (true)
{
client = server.AcceptTcpClient();
data = null;
NetworkStream stream = client.GetStream();
int i;
while ((i = stream.Read(bytes, 0, bytes.Length)) != 0)
{
data = System.Text.Encoding.ASCII.GetString(bytes, 0, i);
data = data.ToUpper();
byte[] msg = System.Text.Encoding.ASCII.GetBytes(data);
SendMulticast(MultiCastIP, MultiCastPort, msg);
}
client.Close();
}
kind regards,
Rick

The TIME_WAIT state for a period of time is normal/default socket behavior.
If you're absolutely sure all data is sent, then you may be able to set the
LingerState to on/0sec:
LingerOption lingerOption = new LingerOption (true, 0);
client.LingerState = lingerOption;
You also should call Close() on your NetworkStream
