private void Navigate()
{
//this.tabControl1.SelectedTab = this.tabPage1;
//this.tabControl1.SelectedTab = this.tabPage2;
//this.tabControl1.SelectedTab = this.tabPage3;
//this.tabControl1.SelectedTab = this.tabPage4;
//this.tabControl1.SelectedTab = this.tabPage5;
}
This is what I have. I need with I click the Next button it on to tab 2 if I press again tab 3 and so on. I click the previous button it goes backward.

So keep track of which tab you're on and use that as the basis for navigation.

Need help in writing this.

Name 2 buttons "btnPrev" and "btnNext". Name a tab control "tabControl1". Create "Click" event handlers for the two buttons and put the code in them like this:
private void btnPrev_Click(object sender, EventArgs e)
{
if (tabControl1.SelectedIndex > 0)
tabControl1.SelectedIndex--;
}
private void btnNext_Click(object sender, EventArgs e)
{
if (tabControl1.SelectedIndex < (tabControl1.TabCount - 1))
tabControl1.SelectedIndex++;
}

Hi,
I found several answer about typedef with "using" but it doensn't fit to my problem...
I'd like to do something like this in C#
typedef float Real;
because, someday I may need to create my own class Real and then I wouldn't need to replace every word (I know I could use the visual studio editor "Replace All" option, but I think it's too dangerous if I'm in the middle of a project that could have up to 1000s of files.
Thanks,
Dirso

However, you could create a wrapper class at the expense of speed. It really is unfortunate that you cannot inherit base types in .NET.
Another option which is more sloppily elegant ... Create a new class whose only method is a static, implicit operator that converts between itself and the type you want.
Then declare your code using floats in the following manner:
float myFloat = ((MyClass)5f);
When it comes time to change the value of the float change the implicit operator's type and you will get compile time errors showing you every location that needs to be changed.

What have you tried so far? In what way does it not fit?

C# has a very natural equivalent for this:
The C# equivalent of:
typedef float Real;
is simply:
using Real = System.Single;
Note that you can't use the C# aliased name on the right side, it must be the 'proper' type name.

My problem about that is that I'd like to define it once, not in every single file.
Thanks anyway for trying,

Oh, then pass your code through the C-preprocessor, it's good at hiding details like that.

I have a reference to a web service, which has its URL "hard-coded" (not really, because it is part of the settings).
Here, we must fetch application settings elsewhere (it is the SSO configuration store).
I could do the following:
MyWebService s = new MyWebService();
s.Url = "some url";
s.MyMethod();
But I would prefer the following:
MyWebService s = new MyWebService("some url");
s.MyMethod();
I noticed that the C# code generated declares the MyWebService class as partial. Is there a way I could provide a partial implementation of that class, where there would be a constructor taking a URL as its parameter?
I tried, but it did not work. I remember that you could do it with editor-generated typed datasets.

I would guess you can create a partial class with a constructor that takes the URL. You said this didn't work - what happened exactly?

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.

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?
