what you mean by load file?
if you mean you want to load the file in browser without creating on disk,
well it can be done but with a trick like this:
Read the file from db(access) into string variable and then write that string variable into a temp html file and execute that htmlfile in browser, and after loading the file into browswer (may be 1 or 2 second delay be required) delete that temp html file
let see if this works

I did it before, it works , but this solution ,for network with different permission may cause some problem.
I want load browser directly with htmltext, without create and save file.

well then you need to use memory stream as the source for the browser to read the html contents, but im not sure about this that either browser will read from this memory stream or not
what else can be done is you embed the browser control (if IE) in your application and then try to send html text to that browser control programmically

If you want to load HTML file in a webbrowser control, Its the straight forward way to set the property value of DocumentText of the Webbrowser with the HTML string.
Example,
If your Webbrowser control has instance name, webBrowserControlMyBrowser then
string htmlString = " Hello World ";
webBrowserControlMyBrowser.DocumentText = htmlString;
In this way, You dont need to create a file, save and delete etc, moreover, you dont even need to wait for couple of seconds to load. Its the DIRECT way.

No, It was implemented in VS 2005, I've just see that you use VS 2003 in some previous messages

I am creating a new window app and am having difficulty with resetting focus to a form instead of opening multiple instances of the form. I have a menu to open formA for example from the MainForm menu. I want to have the logic be something like (from click of menu from MainForm)
If formA visiblity == true then
{ set focus to formA}
else
{ formA.show}
I can't seem to get the syntax for the if condition and the set focus command back to formA if it is already open.
Any help would be appreciated, thanks!

if (formA.Visible == true)
{
formA.Select();
}
else
{
formA.Show();
}

I tried this but still it does not function correctly. If formA is not visible then it open a new instance no problem. the problem is if I go back and try and open it again, instead of selecting the previously opened form, it opens a new instance via formA.Show() even though copy of formA is open.
If I change visible == true, then it believes an instance is already opened even though one is not opened.
if (formA.Visible == false)
{
// shows new formA form
formA.Show();
MessageBox.Show("New Form");
}
else
{
// Reset focus to currently opened form
formA.Select();
MessageBox.Show("Reset Focus to form");
}

It looks like you partially wrote it in VB
The syntax for the if statement is:
if ()
{
}
else
{
}

Hi,
In my form one datagridview control is there,insert button When we click on insert a new row is added to the datagidview.If we enter values in that new row and click on save button ,the newly inserted row is updated to database.To get this what code i have to write in save button click.
Please help me.
Thanks in advance

first you must set the gridview DataSource:
dataGridView1.DataSource =DS.tables["x"];
then u must add row to the DataTable for exmaple :
a = a+1;
b = textBox1.Text;
dt.Rows.Add(new object[] { a, b});
after click the button to update data in database:
scb = new SqlCommandBuilder(DA);
DA.Update(DS, "tbhazine");
