Not quite. ContexMenuStrip is a new Control, it works slightly differently and has
different events. Good old MainMenu still exists, it is not obsolete, but it does not show
in the toolbox by default. You can add it by right clicking the toolbox pane, and
Choose Items. (Chances are you will have to repeat this when you reopen the project)

If you want to use ContextMenuStrip anyway you will have to adapt, and a more recent
C# (C# 2.0) book would be appropriate...

Thanks

I tried to add Main menu to the toolbox before, but it was already there and showed up as the ContexMenuStrip. Now I tied it again and I see it three times in the list. One of these in the list is in a different directory and it is indeed the old control. I guess once you use it, it shows up different, (or maybe I missed it).

Different events for the newer control would explain allot. I will have to make the best of things until I get another book. I may just want to wait for Visual Studio 2008 which is supposed to be arriveing this month. I see they have a Wrox book out on this already, I really like the Wrox books.

Once again,
Thank you

Hello Developers,

I am trying to plot a sine wave graph and i want it to perform phase shift, frequency shift and amplitude shift. But i have no idea how can i achieve that. I have gone through ZedGraph tutorial and it just tells you how to plot a wave and thats it. But how to change its frequency, phase, amplitude during in time.
Is there any better tool other than ZedGraph for the same purpose or is it possible to do this using ZedGraph only...

Any help please
ta
James

Hi,

For starters I have never used ZedGraph. I do have some experience with several older
plotting components (pre-.NET!)

plotting libraries create a plot starting from either a table of (x,y) pairs, or
a method that evaluates y(x) for any given x within a user-specified range.

Assuming you managed to plot a sine wave, the only thing you must do now is apply
"phase shift, frequency shift and amplitude shift" to the data/method you feed into the
plotter. If you know what these things are, it is easy; if not, you should study your
material before trying to plot the results.

And I guess you would also want to show several curves at once to visualize the net
effect of all those shifts. That too is simple, every plotting library supports a
superposition of graphs (with shared or distinct scales, you'll want them shared).

Why using 'Go To Definition' on .net framework definitions not reveals implementations? [modified]

Sinan Akyuz10-Nov-07 10:56

When we right click and select 'Go To Definition' command on a definition which is defined by .net framework class library why we get only declarations instead of declarations with implementations? Is all the implementations hidden or is there a way to see them as C# code? Or at least can we see them as MSIL in VS2005?

thanks in advance.

You will be taken to the source in VS2008. There is no source supplied for the .NET Framework currently.

You can look at the MSIL if you wish, but I would recommend you get Lutz Roeder's Reflector as it will generate C# code.

Not quite, if you add a new resource file to your project, then add your files to that.

Alternitavely, you can embed the html file (so, set it as an embedded resource in its properties) and access it like this:

System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream("file.htm");

And that returns a stream to the file.

Data from form in DLL

Hello everybody,

here is my problem. I need to create a DLL that runs a form. On this form there are some Data created. I need to get acces to this Data from a Webform. I have allready created the DLL, but I can't run the form.

How can I start running a form in a DLL?
And how can I access data, that is created in this form in the DLL?

Thanks for your help.

I'm slightly confused. You want to get data from a web form or a win form? You need to run the form to get the data from it, is this data the user has just entered, or is the form getting data from somewhere else? If the user is entering the data, is this the same user that will see the webform?

Please clarify your situation because I don't understand it.

I want to get the Data from a win form. I need to run the form, because I'm using special controls to get the data from somewhere. The controls need a win form!

Now i want to display those data on a webform, because i want to host a page where I'm diplaying those data.

So no user is entering something, I just need the data from those controls. And they need a win form.

Am I clear?

You want to get the data from "somewhere". That is a bit vague, isn't it? Why does this data need to arrive through a winform control? It sounds like it is increadibly badly designed. The control should never know anything about where its data comes from, it just receives it.

So, where does the control get the data from? And, where did this control come from anyway?

Hiding columns in a datagrid

steve_rm10-Nov-07 7:35

steve_rm

10-Nov-07 7:35

Hello

VS 2003.

I am trying to hide some columns in a datagrid. The datagrid is bound to a typed dataset data source.

This is the code I have used to set the column width to zero. However, as there are many columns to hide I get left with a bold black line where the column should have been. So the customer doesn't want to see this. This is the code I used, just wondering is there a better way to do this.

Many thanks,

Steve

you can do it by using the flag, visible set to false, of the column as

if(col.HeaderText == "xyz")
{
col.Visible = false;
}
