Hi,
I'm really hoping for an easy answer to this issue. I have a client device that uses a hardwired connection to communicate with its server if it is in a docking station. If lifted from the docking station the hardwired connection is disabled and it switches to its wireless connection. This is where remoting stops working on the serverside.
The client device has 2 network cards with different IPs, one for the hardwired connection and one for the wireless connection. When switching to wireless/hardwired the client is still able to send messages to the server, but apparently the server is still trying to reach the client on the connection it initially used so the return messages fail.
How is this fixed? Where is this fixed? I've tried to call RemotingServices.Configure again but it seems you can only call that once. Unregistering and re-Registering channels doesn't seem to work either. Any ideas would be greatly appreciated! Solutions even more!

You don't, call the Refresh() method to cause the form to repaint.

Actually, Invalidate() is what you call to force a paint event.

The application heartbeat status shall be written to the Event Log(event viewer) at regular interval of 15 minutes. It is done to know the status of application whether it is up and running. The application is pinged at the mentioned url and the status of the application is known.
I want to know if there is any implementation code for above requirement?
Thanks & Regards,
Praveen.

That you can find in IIS Error Log as well.

I didn't get you. what you mean by IIS Error Log.please elaborate.

If you want to check the errors generated in your web application then you can check IIS Log. But it is troublesome to check the error in the log. You can use LogParser which is free utility from Microsoft to check the errors for your web application. If you want to create a custom error logger which will ping and check whether the application is up and running or not and set the status to the windows event log, then I would like to recommend you to use Enterprise Library by Microsoft.

Hi there,
I want to add dynamically checkboxes to the datagridview rows which displays data on textchange event of a textbox using LIKE query.
On clicking checkboxes I want to go for further coding.
Please help.

Hi,
That question was raised by me itself but, I couldn't find right answer.
One who suggested me at design time instead of runtime.
Please help.

Does the textbox reside inside the grid view or some where else? Are you trying to say that on the textchanged event of the textbox, checkbox lists should be created with the data that depends upon the textbox's text right.
You can add a Template Column in the gridview. Drag a checkbox list in the ItemTemplate. Set the autpostback to true ande define an event. This event will be common for all checkboxes in your gridview. Now in the RowDataBound event of your gridview, just set the items of the checkbox list depending upon the data that you want to bind. As you have already set the event with the checkbox list, you can do what ever you want in the checkboxlist selected index changed event.
It's a bit long discussion but I hope something is clear now If I took your words right.

Sir,
Your first statement was right that I m having textbox outside to that of datagridview.
You gave the code which was in ASP.NET but,I m working on C# Windows.
Even I succeeded in adding checkboxes at runtime on textchange event of external checkbox on your behalf....Thanks.
But, now I m quering about how will I get the appropriated row record on clicking respective checkbox on the row ? Is there any event about databinding events to succeed further?
I want to check it for furher process.
Please help.

You can add a COLUMN of checkboxes, you cannot add a chackbox to a single row. I use the following:
DataGridViewCheckBoxColumn oDGC = new DataGridViewCheckBoxColumn();
oDGC.HeaderText = "Sel";
oDGC.Name = "Sel";
oDGC.AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCells;
oDGC.FlatStyle = FlatStyle.Standard;
oDGC.CellTemplate = new DataGridViewCheckBoxCell();
oDGC.CellTemplate.Style.BackColor = System.Drawing.Color.Beige;
oDGC.ThreeState = false;
oDG.Columns.Insert(iCol, oDGC);

}
public void bookmarkPaste(Word.Document aDoc, string bookmarkAdi, string data)
{
try
{
object bookmark = bookmarkAdi;
object missing = System.Reflection.Missing.Value;
object pasteType = Word.WdPasteDataType.wdPasteHTML;
DataObject clipDO = new DataObject();
if (aDoc.Bookmarks.Exists(bookmark.ToString()))
{
Word.Range rangeTbl = aDoc.Bookmarks.get_Item(ref bookmark).Range;
clipDO.SetData(DataFormats.Html,HtmlClipboardData(data));
Clipboard.SetDataObject(clipDO, true);

// Get lengths of chunks

Hello,
We have choosen to use Microsoft Enterprise Library in a project that I am involved with. We wan't to write messages to the windows event log with Enterprise Library. I have succeseeded to with that but I have a question with information regarding the stacktrace. When I look at the event log (Windows 2003 server) I have the full stacktrace listed in the event log and in the bottom of the written event I have the message. I wan't to know how to write only the message to event log. I don't wan't to see the full stacktrace.

How did you checking the use id and password? Where is the code? Did you check with String.Equal() or what ?
|

this is the Code I am using
SqlConnection Con1 = new SqlConnection("server=.;database=ab;uid=sa;pwd=max");
Con1.Open();
SqlCommand cmd1 = new SqlCommand("select UserName,Password from mads Where Username= '" + usrtxt.Text + "' and Password ='" + passtxt.Text + "'", Con1);
SqlDataReader dr = cmd1.ExecuteReader();
dr.Read();
if (dr.HasRows == true)
{
prj = new Project_Details(usrtxt.Text);
prj.Show();
}
dr.close;

SQL is case insensitive. You have to force SQL to turn on the case sensitivity for the select query. Just add the following clause with your select query:
COLLATE SQL_Latin1_General_CP1_CS_AS
Use COLLATE SQL_Latin1_General_CP1_CI_AS for case insensitivity.
It can solve your problem.

If this is your live code, Please be careful about SQL Injection.

Check out the following code:
if (string.Compare("hello", "Hello", false) == 0)
{
//do whatever you wish
}
The third parameter makes the string comparison case sensitive.

Hi, i have a problem about threads with windows forms.
When users's sessions ended, i want to show a dialog box to inform them to relogin and then to show the relogin form.
It was ok until i use threads in some forms to improve performance.
When a thread reveices a session error, it shows the relogin form. Actualy i use invoke on the main thread.
But while the dialog form is shown, another thread can make a service call and receive the same session error and so tries to show the same relogin form. But it is clear that only one instance of relogin form must be shown at the same time. So i have to use a locking mechanism. But since the thread that shows the dialog box is the main thread, this causes the main thread enter wait state. So the application freezes.
public bool Relogin() {
Interlocked.Increment(ref waitingThreadCount);
event1.WaitOne();
if(this.loginResult == null) {
loginResult = ReloginForm.Show();
}
Interlocked.Decrement(ref waitingThreadCount);
if(waitingThreadCount == 0) {
loginResult = null;
}
event1.Set();
return loginResult.Value;
}
