the dirty way :
<br />
string xmldata = new Webclient().DownloadString("http://your.desired.url/file.xml");<br />
XPathDocument myXPathDoc = new XPathDocument(xmldata);<br />
... //go on with your stuff.
maybe you want to structure it, add exception handling or use it in an async manner,
but it´s probably the right direction if you want to use a url instead of a local file.

I need to embed a cursor file into the application. How to do it?
The procedure what i have followed is:
* I added a existing cursor file into project.
* Changed the "Build Action" to "Embedded Resources".
* Code:
Cursor newCur = new Cursor("xyz.cur");
this.Cursor = newCur;
But it is throwing exception "Could not find file C:\App\rotate.cur".
I want to embed the cursor in my application.

In the solution explorer, go to the cursor file's properties and set Copy to output directory to Copy if newer.
Cheers,
Vikram.

hey there
i hav a lil problem with a toolStripButton
the following code is in my app
<br />
private void BtnSave_Click(object sender, EventArgs e)<br />
{<br />
method();<br />
}<br />
<br />
private void dataGridView_CellEndEdit(object sender, DataGridViewCellEventArgs e)<br />
{<br />
save = true;<br />
}<br />
<br />
private void FrmTimeCategories_FormClosing(object sender, FormClosingEventArgs e)<br />
{<br />
if (save)<br />
{<br />
string option = MessageBox.Show("Would You Like To Save The Changes?", "Question", MessageBoxButtons.YesNoCancel, MessageBoxIcon.Question).ToString();<br />
<br />
if (option == "Yes")<br />
{<br />
method();<br />
}<br />
else if (option == "No")<br />
{<br />
MessageBox.Show("Changes Will Be Lost");<br />
}<br />
else if (option == "Cancel")<br />
{<br />
e.Cancel = true;<br />
}<br />
}<br />
save = false;<br />
}<br />
<br />
private void btnDeleteRow_Click(object sender, EventArgs e)<br />
{<br />
foreach (DataGridViewRow row in dataGridView.SelectedRows)<br />
{<br />
TimeCatTable.Rows[row.Index].Delete();<br />
}<br />
<br />
TimeCatTable.AcceptChanges();<br />
SqlCommandBuilder sqlBuilder = new SqlCommandBuilder(dataAdapter);<br />
dataAdapter.Update(dataSet, "TimeCat");<br />
}<br />
<br />
public void method()<br />
{<br />
SqlCommandBuilder sqlBuilder = new SqlCommandBuilder(dataAdapter);<br />
dataAdapter.Update(dataSet, "TimeCat");<br />
<br />
save = false;<br />
}<br />
now the problem is this... the call to method() doens work in the toolstripbutton (btnSave) click handler. the program defenetly goes into it (i put a messagebox in to test that) but its doesnt save the changes to my database, but the method() in the formClosing handler does save it!
i put a normal button on the form aswell just to see and that worked too... im confused with this.
can anyone plz tell me why this happens?

HarveySaayman,
Are you getting any exceptions? Put a try{} catch{} around "method()".
Also, It might be a good idea to go through the "dataSet" rows in the "method()" and print out the values that you are about to update to actually check, the value which you want is in there.
Regards,
Gareth.

i tried the try catch block, no exceptions. if i call method() from the btnSaveClick messageboxes will show and variables do change but these two lines wont do what they are supposed to
<br />
SqlCommandBuilder sqlBuilder = new SqlCommandBuilder(dataAdapter);<br />
dataAdapter.Update(dataSet, "TimeCat");<br />
if a put a normal button on the form and call method() with that it works perfectly and also if the form closes and the dialog asks if u want to save. its just the btnSave (toolStripButton) that wont do it
thanx

When I'm trying to debug the sorce code downloaded from the following site, I got the exception, "An error occurred: Cross-thread operation not valid: Control 'stbMessage' accessed from a thread other than the thread it was created on."
"http://www.codeproject.com/KB/game/tictactoenetwork.aspx",
When I made exe to the solution, its working very fine.
Please guide me to debug the code.
Thanks and Regards,

Winforms controls are not thread safe. If you must update a control from another thread of execution, you should use a delegate and then call this.Invoke() from the form.

Hi: can anyone tell me how to set up an input class for XNA that works? I thought I've done it right, but when it checks input, nothing happens. (So far, it's only supposed to exit) I just want the basic idea o how I would go about doing this, even though it's simple. (I have Game1 class and Input class)
Thanks in advance.

Hi all,
I have write a service to automate a server application. To start the application I need some IPs which are stored in a database. I read the database and get required IPs on my service and run the server.
Up to now everything is ok.
Now I want to check that there is multiple instance are available. Because I can start only one server at a time. To do this I try to use MUTEX, as in C++(my server is written on C++). Can you guys give me a help. I don't know that higher concepts to handle in C#.
Thanks a lot. 
I appreciate your help all the time...

Multiple instance of what? I don't think you can have multiple instances of a Windows service anyway. If it's a regular app that you only want one instance of, C# has a Mutex in System.Threading which fits the bill. Google is your friend[^]
Cheers,
Vikram.

hello,
my web app use DirectoryServices to query Active Directory. On customer side i'm getting following error:
The time limit for this request was exceeded.
This error appears ~2 minutes (~120 s) after method FindAll() had been launched. Google this error description i found:
Active directory queies can take a bit of time to process so you may have to extend the time available from the default. You can do this by adding a <httpruntime> section to the web.config file with an executionTimeout attribute. Take a look at
<a href="http://msdn2.microsoft.com/en-us/library/e1f13641.aspx">http:
default value for executionTimeout attribute is 110 seconds. So it seems my error appears because of timeout.
BUT customer says - other LDAP tools didn't produce such error, and find objects quickly.
So, why is my search too sloooooooow?
thanks,
max

What OS? When I wrote some LDAP code on Windows 2000 using COM a while ago it was blazing. Then I executing the same thing on XP and it would take about 10 minutes. I never did figure out the problem.

Dear All,
I have a treeview with several parent and child node. If I click on a parent, I want to invoke a method. If I click on a child , I want to invoke another method. The same method for the parents , and the same method for the childs.
+ Parent Node 1
- Child node 1
- Child node 1
+ Parent Node 2
- Child node 1
This is the code I dreamed to achieve this. But .. for some reason it doesn't work. If I click on the child, it works .. however, the parent method is not fired when I click on the parent. Can somebody point me in the right direction with whatever it is that I'm doing wrong ?
private void treeView_AfterSelect(object sender, TreeViewEventArgs e)<br />
{<br />
if (e.Node.Parent.IsSelected)<br />
{<br />
MessageBox.Show("This is the parent node");<br />
}<br />
<br />
else<br />
{<br />
MessageBox.Show("This is a child node");<br />
}<br />
}
Thanks 
|

Do you mean the after select event is not fired, or do you mean that the wrong message box shows ?
I'd probably set the tree view items up with tags so you can tell what level they are on. Or check if the node has children, if the tree is only ever one level.

Christian,
Thank you for replying so quickly. The Afterselect is actually being called, and the second Messagebox ( when selecting a child ) comes up correctly .. but the first one isn't. Selecting a child with my code works fine, but not the parent. To me , that doesn't make sense, as it really checks if the parent is selected or not, or else it wouldn't make it to the else section and show the child messagebox.
