As I said already: The Size object is immutable. That means that once created it does not change. You cannot set the Height of a Size object because that would change the object, you have to create a new Size object and use that
In your code that means the line
dataGrid1.Size.Height = groupBox3.Size.Height + dataGrid1.Size.Height; cannot work because you are attempting to set the Height property on an immutable object. (If the property is on the left hand side [LHS] of the equals operator then that is a set operation, if the property is on the right hand side [RHS] of the equals operator then that is a get operation)
So, going back to what I said, you have to create a new Size object. Something like this would work
Size newSize = new Size(dataGrid1.Size.Width, groupBox3.Size.Height+dataGrid1.Size.Height);
dataGrid1.Size = newSize;
By the way, you should really attempt to name your controls (and all variables) with sensible names. groupBox3 and dataGrid1 are not self-explanatory. You will have difficulty in determining what you were trying to do if you come back to look at the code later.
Does this help?

You could put the groupbox in a panel, and then when you hide the groupbox, set the Dock property of the datagrid to DockStyle.Fill

thx for tip!

And you may try :
dataGrid1.BringToFront();

Hi guys
I am trying to write an application, which can load test my ASP.NET Web Service.
Basic idea is:
I have lot of functions in my web service. I want to execute each function (Right now i am doing it using SOAP) and
then want to calculate processor time, cpu utilization, request-response time etc. Can you tell me some good
articles about that, from where i can get some relevent information? Also can you tell me some basic article about
calculating performance counters?
Thanks
Sumit

Hi all,
Salamander's .NET Protector makes a claim that it completely prevents decompile and disassembly of C# applications, which means that the source code cannot be seen in ILDASM and Reflector etc. They also claim that their product is better than an obfuscator. However, their product pricing being so exhorbitant (US$ 1899 or so per license, which is even much more than the pricing of MS Visual Studio Professional Ed.), I first wanted to confirm whether it is really a useful product? Is it a worthwhile product and is it worth its value? Secondly, do you think that their claims about the product are true claims?
Can anybody who has used that product share his experience?
Thanks in advance.

How many licenses will you need? If this was being bought for the company I work for, we'd probably only get one license because it won't be an everyday task by people. It will be a task done towards the end of the project (and maybe a few times during [for testing purposes]) so, unlike Visual Studio, it won't need to be on everyone's machine. Probably it would just be needed on one machine.

You might like to look at a book such as Head First Design Patterns. It explains design patterns in a very easy to understand way with examples. The examples are in Java, but they don't use much of any frameworks (because they are teaching you to create your own framework) so it is easy to see how to do the same thing in C#.
Also, don't be overwhelmed by the size of the book - its full of pictures and diagrams and it is very light reading.

I am building a setup using Visual Studio .NET 2003.
The requirement is, during installation process we need to ask user for License key. If key is valid, user should be allowed to go ahead with completion of setup. If user exits the key request form, setup should rollback.
The key application for key acceptance and validation is ready. It returns true if key is valid, else it returns false.
How can we check these values during installation and commit or rollback the installation accordingly?
Thanks in advance.

Hello,
Now, I develop communication tool using udp protocol.
When I send data, I use send() in C#'s Socket class.
If a recipient tool is exist, a sender send it.
If not, sendTo() waiting some seconds.
Maybe after 10 seconds, the error occured.
I'd like to send it no waiting whether recipients is exist or not.
I investigated Socket class( expecially, SetSocketOption ),
But I have no idea.
If you have some ideas, please tell me.
Thank you in advance for your kindness.

1. You can use ODBC and read Excel data. That data you can store anywhere you want.
2. Using Excel.Application object, you can read information form Excel sheet and save it to array or where ever you want.

I have say a 100x100 array of gray values (0 to 255). How can I create a 8bpp bitmap from this array such that 0 maps to black 255 maps to white?
In particular how to you set the ColorPalette for a 8bpp image; I want 0 to map to black 255 to white?
I tried following code but its giving me problems:
PixelFormat pf = PixelFormat.Format8bppIndexed;
byte[] Scan0 = CalculateIntensityValues();
Bitmap bmp = new Bitmap(100, 100, 100, pf, Scan0);
how to convert Scan0 from byte[] to IntPtr?
|

Scan0 is a pointer to the bitmap data. The easiest thing to do is to create the bitmap, then get access to the pointer and set the values in an unsafe block. None of this code is setting up a palette, as far as I can see.

Dear *.*
I'm a c#-rooky *g*. How can I call word/outlook from an existing c#-app. The users just want to start word or outlook by pressing a simple button within the form.
An additional nice feature would be for example submitting the email-adress to outlook or something like this.
regards
Klaus

You need to add reference of Word and outlook libraries in your project. Then you can do whatever you want using Application objects of these libraries.
If you are using Office Xp, library 10.0 will be available on your system. And if it is 2003, you will see library 11.0
Enjoy
