error CS0234: The type or namespace name 'Management' does not exist in the class or namespace 'System' (are you missing an assembly reference?).

I want to use a context menu with a tabcontrol. How can I detect which tab was right clicked?
|
|

In the event handler for the MouseDown events of the TabPages, you can check:
private void tab_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
{
if ((TabPage)sender == tabPage1 && e.Button == MouseButtons.Right)
}
However, if the purpose of detecting right click on a tab page is to invoke the context menu, then such a detection is not even needed, as the same objective can be achieved without such detection in the following manner.
In the designer, draw a TabControl on you form. Draw the TabPages on this control as per your requirements (say, tabPage1 and tabPage2). Now, draw the context menu's for each TabPage as per requirements (say contextMenu1 and contextmenu2) with the required menu items. Select tabPage1 tab in designer and in its properties window, set the ContextMenu property to the value of contextMenu1 object. Similarly, the ContextMenu property of tabPage2 can be set to contextMenu2 object. Compile and run the program.
Now, when you right-click anywhere inside the area of tabPage1, you'll automatically get contextMenu1. Similarly, right-clicking anywhere in tabPage2 will show the contextMenu2 automatically.
Thus, there is no need for you to detect as to which tab was right-clicked.

Thanks for your reply. First of all I want to make one thing clear. I'm trying to click the actual tab, not the tabpage. I also want to use the same context menu for different tabs. Otherwise I would have no trouble finding out which tab was right clicked.
I have already tried your first aproach with one difference. I create the tabs dynamicly with the following code (somewhat pseudo):
TabPage tpNew = new TabPage();
tpNew.Text = "Some text";
tpNew.MouseUp += new MouseEventHandler(tpNew_MouseUp);
tcTabControl.TabPages.Add(tpNew);
The eventhandler tpNew_MouseUp is never called.
I can hook up the context menu a number of ways that I am aware of. Even on the TabControl itself, but I have no idea how to find out what tab were right clicked. Is it possible to fins out which of the headers that are under the X and Y coordinates when the mouse was clicked?

this.odbcConnection1.ConnectionString = strConnect;
I got error as below:

Is there a way in gdi+ to set text kerning?
I tried using SetTextCharacterExtra with current graphics HDC, but it seems
to work randomly.
For example with arial font it works up to size 13 (with extra spacing set
to 20)
Once I try to draw with size 14 it just ignores the setting.
Is there some limitation to that function, or is there any other I can use?
Thanks.

Hi, i've created a program and i want to install it on a computer. It says i have to install the .net framework before running the program. is there an other way to install it without the .net framework? (copy some dll to surtain directories??)

Nope. Not that anyone is going to support anyway...

The quick answer to your question is no. One of the most important part of the .Net Framework is the CLR “Common Language Runtime”. This block of code provides the environment in which .Net programs are executed in. You can download the .Net Framework from Microsoft free of charge at ( http://www.microsoft.com/downloads/details.aspx?FamilyID=262d25e3-f589-4842-8157-034d1e7cf3a3&DisplayLang=en ) This download includes all that is needed to run applications developed under .Net Framework.

Hi all. I haven't found an answer to this through quite some googling and searching, so I hope someone can provide some tips.
Here's the deal:
How can you call unmanaged code from a C# app?
Yeah, I know about a few ways to do it, but they all seem to rely
on the DllImport attribute initialized with the name of the DLL to be called at compile-time.
For instance:
[DllImport("msvcrt.dll")]
in my case, I will not know the name of the unmanaged dll to be called
until run-time. The name of the dll will come from a config file.
So, imagine
string unmanagedDll = this.GetUnmanagedDllNameFromConfigFile();
and now, is there any way to *programmatically* do the equivalent of
[DllImport(unmanagedDll)]
?
Thanks in advance for any suggestion,
F.O.R.

I am planning a new project and got some great ideas on how to do things.
Since it is version 2.0 of the project and the whole application needs a rewrite (the first version is approx. 3 years old now and was done without a decent design) I might as well try something new.
I want to build the application using the 3-tier design: GUI, Business Logic and Data-Access. I want to make it possible to both use a database and a webservice for the data-access. Also I want to add offline-capabilities to the application so that if the webservice fails the users can continue their work as normal.
So far my testing with hand written proxy classes for the webservices and the classes for the database is going great. It really seams to work, you can switch between them without much hassle.
But my big question is, should I use datasets or should I write my own custom business logic classes. I like the dataset because it's a lot easier and it works great. Hand-made business classes are not really my favorite since I don't exactly know how to pick that up.

I think you shouldn't think of the bussiness logic as a matter of chosing the right one between DataSet and biz logic classes.
Think about the key concepts such as transactions, security (authorization and authentication), work flow, retriving paged data, user sessions, etc..
By considering all these you are able to find a good, scalable, maintainable solution. However finding the right solution is a lot difficult.

I already have a good solution for security, the main problem is really the data. DataSets offer huge advantages when it comes to working speed. I don't need to write all the classes for my application instead I use a DataSet to retrieve and update data.
Do you know any examples of paged data access and using transactions combined with the use of datasets?

After reviewing the enterprise library I am pretty convinced that it would be quite useless to make something like that myself. The first tests look good and the framework is easy to work with (aside from the configuration wich is rather confusing sometimes)
Thanks for the help
