Hi Colin,
I changed it back as it was before:
for (int = 0... 50, i++)
What do you mean by preset the textbox's up?
I tried that, but it doens't recognize the 'Text' property.

You have a loop that gets the text boxes that you need then processes them. The way it is finding the text boxes is inefficient. Do this step only once on the form load by populating a TextBox array. When you need to loop over all the text boxes, you are looping over a pre-built textbox array which is much more efficient than lookin up each textbox by name.

Hi Colin,
I changed that now.

Yustme wrote: TextBox[] textBox = new TextBox[50];
That initialises a new EMPTY array of text boxes
Yustme wrote: textBox.Text
You are attempting to get the text property from the ARRAY. You need to iterate over the array
e.g.
for(int i=0; i<50; i++)
{
TextBox currentTextBox = textBox[i];
if (this.answer[i] == int.Parse(currentTextBox.Text))
{
}
}

Hi Colin,
That worked good, thanks!
Somehow my answer[i] is reversed. It contains the answer of the first label in the last index, instead of in the first index.
How can i change the way the array is filled?

How are you filling it now?

Hi Colin,
I think i found the problem.
It was the way that C# generates the code where it put label1 at the bottom and label2 above it and so on.
I changed that. So it works fine now.

Hi,
i am using c# and sql server 2000. i want to execute this below query in my application using oledb dataadapter.
sql query:
select preferencevalue from ParticipantPreference for xml raw;
(also the above column contains an XML data as a value in it.)
this query gives me an xml formatted correct output when i use SQL dataadapter.
If i use oledb dataadapter my result is in BYTE array format...
plz help me.
|
|
|
|
|
I think it has something to do with oledb. Can you try the following with that byte array?
byte[] data = ...;
ASCIIEncoding.GetString(data);

I wrote a program needs to connect to remote servers,
my problem is - my program throw an exception when i try to connect from firewalled or proxy environment. the question is:
How can i import IE settings to my program?
OR "at least"
How can i the proxy settings in my program?
please help me with a piece of code or at least ClassName
please reply...
|
|

|

Well, as far as getting the proxy settings from IE -- You can grab the ProxyServer value from HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ProxyServer (REG_SZ); how you use this depends on what you're connecting to obviously...
<br />
RegistryKey key = Registry.CurrentUser;<br />
key = key.OpenSubKey(@"Software\Microsoft\Windows\CurrentVersion\Internet Settings");<br />
Console.WriteLine(key.GetValue("ProxyServer"));<br />

throw new Pop3Exception("Connection to server "+ popServer + ", port " + port + " failed.\nRuntime Error: "+ex.ToString());

Hi all,
I retreive some data (Attendance data) from SQL Server and show it in dataGridView object. After that, I want for example use the data to count the number of attended days and absent days for a single person. There is time and date column, and I want to use it to calculate attended and asbsent days without sending additional query, Just use the retreived data in DataGridView for that pourpose.
Example for a single row with data :
FingerprintID | DateTime | FunctionKey | InOut
11200 7/12/2006 11:44:00 AM 1 Yes
It's important to know that I can't modify the current database structure, I have to use it as it is.
so, how can I do that?
|
|
|
|
|
If you're using a dataset to display the data you can iterate through the rows in the datatable inside the dataset that is being displayed. There you find these fields that can be used to calculate the absent days, etc.
e.g.:
foreach(DataRow row in dataSet1.Tables["SomeTable"].Rows) {<br />
<br />
}

i think it is a simple question but i am not able to figure it out.
My problem is that i am using a combo box in the form and i have only two items predifined in it. I want the user to choose only one of these two items and not being allowed to change or right in the combo box. Meaning i want the combo box not to be editable.
N.B: i am using VS2005
Thanks in advance

my requirement is when the user clicks logout button on my application. i have manually close the already displayed messagebox and have to show the login screen. Is there any option to manually(thru code, as like as user pressed cancel button on the messagebox) close the message box.
Note: Here iam not talking about timeout messagebox, i want to manually close the message box.
Thanks and Regards,
Srini
