Good. Glad someone else answered properly. I was under the impression you were trying to accomplish something else. I thought you wanted Form2 to remain open and clicking on the button in Form2 changed some values or output in Form1.

Hi,
How to perform delete with datagridview.Please provide me code for this delete operation.
Thanks in advance.
|
|
|
|
|
You have to delete the datarow from the underlying datasource. The gridview will update itself to the new situation.
DataTable.Rows[index].Delete();
Simple as that
WM.
What about weapons of mass-construction?

datagridview.Rows.Clear();<br />

My code:
New line:
TLNode tln1 = new TLNode(1, treeList1.Nodes, new_item.Name_Link.Text, new_item.Link.Text);
treeList1.Nodes.Add(tln1);
This is new folder:
TLNode tln1 = new TLNode(1, treeList1.Nodes, new_folder.textEdit_New_Folder.Text, "");
tln1.HasChildren = true;
TLNode tln_children = new TLNode(2, tln1.Nodes, "", "");
tln1.Nodes.Add(tln_children);
treeList1.Nodes.Add(tln1);
If TreeList hot have folder - Ok! (new node can have focus)
If TreeList have folder and it is close - Ok! (new node can have focus)
If TreeList have open folder - new line in TreeList not can have focus.

I'm using the System.Diagnostics.Process class to launch processes. I would like to trigger an event when a process exit. Do I have to use the Process.Exited event. How do i use it?

Yes, unless you want to use the WaitForExit method.

Set the EnableRasingEvents property to true, and prescribe to the event as usual.

process.EnableRaisingEvents = true;
process.Exited += new EventHandler(process_Exited);

Hi,
I've been seeing of lot of Lua everywhere lately and i was planning to use it in one of my C# projects. i found this:
Lua interface[^]
basically what my application does is scrpae some information off a webpage. Since the website pattern could change anytime, i decided to use Lua for do the screen scraping. What would be better -
have my C# application get the source of the wepage and pass it to the Lua interface for data extraction and then have Lua return the extrcated data to my program
--or--
Make Lua, get the source of the webpage itself, extract the data itself, and then pass the data to the C# Program
I'm really confused (like I always am ). Could someone help me out here?

That depends on the reason why you want to use Lua for this. If it's good for requesting web pages, use it for that, otherwise not.

Well, after all I've read on the Internet my heads ringing with one thing. Thye all say Lua is excellent for small scripting, stuff like AI, data extraction etc. I came across this sotware called FreePOPs[^]. It basically lets you use your email client with email sites such as Yahoo and Hotmail which natively dont support POP access. They use Lua as the Screen Scraping code. When the design of the emil site changes, the software doent work and you can just download a fresh working version of the screen scraping script. Now, would this help you to reach a decision.

Hello All,
I'm using a BackgroundWorker to check database permissions in the background while my GUI is servicing request from the client. The user enters the db host name, username and password then a BackgroundWorker thread gets kicked off to retrieve the list of databases that are available on the specified host. When the correct information is passed into the textboxes everything works fine. When the user enters wrong information (like a wrong password), I would like to display an error message and disable the combobox that holds the list of available databases.
I'm doing all the database work inside a method called bgWorker_DoWork() which is triggered by the BackgroundWorker.RunWorkerAsync() delegate. It is in this method where I catch an OleDbException that gets thrown when the login to the database fails. Inside my bgWorker_RunWorkerCompleted() method I look at the RunWorkerCompletedEventArgs to see if there were any problem while running the bgWorker_DoWork() method however even when an exception has been thrown RunWorkerCompletedEventArgs.Error is always null. Am I missing something else that I should be doing or is this a bug in the framework ?
|

Are you sure your bgWorker_DoWork() method throws an exception? Did you try stepping through the method under the debugger?
Regards
Senthil

How can I open (popup... not in browser) notepad from browser.
For example: I have some .txt file in my database. I want to open it from browser, where user can edit the .txt file and at this time database will be update internally.
OR
I have some file which I want to open in notepad from browser, it will be display on popup.
JUST LIKE:
Windows Platform where we use
System.Diagnostics.Process.Start(@"C:\Documents and Settings\Billah\My Documents\Data Grid.txt");OR
System.Diagnostics.Process.Start("notepad.exe",@"C:\Documents and Settings\Billah\My Documents\Data Grid.txt");
If I start a process from ASP.NET using System.Diagonistics.Process.Start method. It start in the background (we can see it in task manager), but I can't see it on the browser.
private void Page_Load(object sender, System.EventArgs e)<br />
{<br />
System.Diagnostics.Process.Start("Notepad.exe");<br />
}
IIS Admin Service runs as a local system
So, how can I see the notepad which runs at background?
Thank you
BILLAH

Also, you should realise that it is running it on the server, not the client. If you have the client browser running on the same machine as the server then you are obviously getting confused about what is running as part of the server and what is running as part of the client.
You cannot run applications on the client because it is a security risk for the person using the client.

Create a page with a big text box and load the text in to that. On the post back you can update the database.

Dear Colin Angus Mackay,
Thank you for your reply.
I want a popup notepad which will retrieve data from database. Now it will display in IE. If possible, please Send me a project which display a popup notepad with data or without data where user can edit text and save it in Hard Drive.

Notepad cannot retrieve data from the database. It is beyond the scope of the application.
