Hey all,
I was wondering if there is a way to make specific rows in the checkedlistbox disabled (no able to toggle the check mark). I want to be able to list some options which are mandatory and have others optional.
If there is a better control for this, I'd happily switch ;D
Thanks!

CheckBoxList1.Items[0].Enabled = false;
Where 0 is the index of the item to disable. You could do this in a loop or bind a bool value from your datasource depending on how you're populating it (the CheckBoxList).

What are you casting the item as? When I do that it doesn't work because it's an object, and doens't have the enabled property.

Are you doing this as winforms or asp.net? Either way the CheckBoxList control has an Items property, the Items property takes a collection of ListItem objects, ListItem objects have an Enabled property.

Hey all,
Couple questions for this topic. Firstly, can someone tell me if it's "legal" to update files for my application (stored completely within the folder specified during installation) without prompting the user?
Secondly, I had two avenues I was considering going with this.
A) Keep track of all files in the folder by CRC32, post to a website which checks against the database to see if it matches the latest file, if not, download and overwrite (or if non-existing, just download of course).
B) Keep a tar ball on the server and check the Application.ProductVersion of the application against the server, if it's not the correct version, Process.start() my update manager, close the application (update manager will wait until the process is closed), download the tar ball, and extract (force overwrite).
I think option B) is the easier option in terms of managing, however, I cannot find a way to tar/untar a folder. C# has GZip and Deflate which, I guess, are fine for single files, but not folders. I found 2 libs out there (vwm-cvs and SharpZip, I think), but have found limited documentation. I'd like to just be able to include a dll and be on my way, or use existing features of the framework (optimal).
Any suggestions on a better way to do this or how to make one of these ways work and remain manageable?
Thanks!
Mike

Are you thinking perhaps of ClickOnce[^]?

I can't stand clickonce ~_~ I use that for another application we have and it's too restrictive.

I have the following code:
string sProvider = "msdaora";
string sServer = "CIS-SERVER";
string sDatabase = "ORA92SID";
string sUserName = "kevin";
string sPassword = "abcdefg";
string sConnStr =
"Provider = " + sProvider +
";Data Source =" + sDatabase +
";User Id =" + sUserName +
";Password =" + sPassword + ";";
OleDbConnection oConn = new OleDbConnection();
oConn.ConnectionString = sConnStr;
try
{
oConn.Open();
}
catch (OleDbException e)
{
Console.WriteLine(e.Message);
}
I am getting the error "ORA-12154: TNS:could not resolve service name".
I'm new to Oracle so I don't know what this means. I don't think there's an Oracle provider for .Net installed on this PC, so I'm guessing I'll have to use the default MS provider 'msdaora'.
Of course, I could be totally lost here too.
Everything makes sense in someone's mind

actually this is OOT of this forum, but you have to install oracle client in your installed machine and define service name in tnsnames.ora
for detail try this link[^]
there are many promising results
hope it helps

The problem is that when the provider tries to read TNSNAMES.ORA, it doesn't find entry for CIS-SERVER. Check that there is a definition for this server and the name matches.
TNSNAMES is located in oracle home under \NETWORK\ADMIN or it is routed to somewhere else using TNS_ADMIN either in environment variables or registry.
Hope this helps,
Mika
P.s. I think that you should next time post this kind of question to SQL and Databases forum

Hi, everyone
Now, I'm use to data paging in DataGridView. When I search data on DataGridView that is just show data in present page. I would like get all data rows of DataTable that is being data paging on DataGridView.
For example: pagesize = 5, DataTable have two pages.
data in 1st page:
name age
John 21
N.John 20
Nancy 20
Tomath 21
Jan 22
and data in 2nd page:
name age
Jany 20
Alpha 21
Don 22
Bony 20
Tomy 22
One-page is present page. I'm beginning search data at "name" column as 'Tom'. It is just show one row in DataGridView. This data is correct when it show two rows in DataGridView. That is all. Did the way solve this problem? Can anyone help me?

Hi there.
I want to get ImageFormat of an image ?
How can I do it ?
Thanks in advance.

Reader the header in the image file. The bitmap class also has a PixelFormat get property along with other properties that when combined should provide enough information.

Yesterday was some day, sorry, I had just recently went over some code that was identical up here at the office. MS usually uses enum for that sort of thing I assumed it was an enum and type the suggestion by rote without even thinking about it. Now here I am looking at it and laughing at myself for the error. And people like Leppie think I am never wrong :p
Sorry for the error and thanks for the spot.

Hi all, just a couple of questions relating to SmtpClient and the Send() method.
According to MSDN the method blocks until the e-mail is transmitted. I don't really have a need (at least not now) to send e-mails asynchronously so for my purposes this is fine. But what exactly does it mean if the "e-mail is transmitted"? Does that mean I can relax in the knowledge that the recipient will receive his e-mail the next time he connects to his mail server or am I simply guaranteed that my SMTP server received my command and passed it on without problems?
In other words, if the function returns without throwing an exception, is that a guarantee that the recipient will receive the message or can something still go wrong after that point which will only be caught if I send the message asynchronously and implement a callback when it's delivered successfully?
Finally, if someone would be so kind as to illustrate to me how you would wrap your SmtpClient.Send() method with exception handling so as to ensure that an e-mail is sent or the failure is reported properly I would appreciate it very much. Don't worry about illustrating how to set up the SmtpClient, I know how to do that.
