Hi Jimmanuel. I have used the below and I get an error when it does the calculation. Am I doing this right?
int lastUsedRow = objSheet.Cells.SpecialCells(Excel.XlCellType.xlCellTypeLastCell,
Type.Missing).Row;
And this is where I add it into the formula.
objRange = objSheet.get_Range("E1", System.Reflection.Missing.Value);
objRange.Formula = "=SUM(J4:J[lastUsedRow])";
objRange.FormulaHidden = true;
objRange.Calculate();
objRange.Font.Bold = true;
objRange.Font.ColorIndex = "5";

|
|
objRange.Formula = string.Format("=SUM(J4:J{0})", lastUsedRow);
it might also be a good idea to do some error checking to make sure that lastUsedRow is valid. I don't know what would happen if you tried summing from J4 to J0 for instance . . .

I have a server that upon receiving a client request would create a socket in order to send/receive data to/from the client. I'd like to be able to send this socket to another application - through http - so that this app could "talk" with the same client using the same socket. Is it posible? If not is there another way to keep the server-client connection alive to be used by another app?

Not under normal circumstances, but far back in my mind I recall seeing someone blog about this on MSDN blogs a good 3-4 years back. (I did a search, but cant find it now)
Your other alternative is using Remoting, and let the other application communicate with your socket on via the socket-holding application.

You can use the builtin stuff, but I prefer NSIS. InnoSetup is also very simple and easy to use.

Hello,
I am beginer in C# programming..
When I add button on the form, and run the project- form doesn't change at all (the button doesn't exist on form). I put Visible= true in property for that button, but it seems it doesn't work..
What is the problem, and how can I solve it?

I don't know. You've not explained HOW you are adding the button.
|
|
|
|
|
I just dragged and dropped on the form, and set Visible= true..
When I debug and entered into the InitialComponent method, there are code for that button
(....this.btnSend = new System.Windows.Forms.Button()...)
|
|
|
|
|
Is it in a container that is not visible, such as a panel or groupbox?
|
|
|
|
|
No, it isn't in any container..
|
|
|
|
|
You are using form.Controls.Add(...); right? Because if not, then thats the problem.

I use this.Controls.Add(this.btnSend) in InitialComponent method..
|

If you're manually editing the InitialiseComponent method, then any changes will be lost when you use the Form Designer

Some snippet of XML is added to the project file that tells it about the assembly.
An item is added to the tree view that represents the solution to show that the reference has been added to some project. You'll see this if you expand the appropriate references section.
I'm sure other things happen at the point of addition in the IDE, but I really don't see how any of this is relevent to anything.
