How do they get into your drop down list to start with ? That's obviously where the problem is.

Well, I believe I just followed the steps outlined in the MS documentation to do this. I set my main form's IsMdiContainer property to true. I added a menustrip via the designer. The entries are added by setting the MdiWindowListItem property of the menuStrip to the desired menu item (In my test case, "windowToolStripMenuItem") from within the designer and then I call the following when I want form2 to show:

form2.MdiParent = this;
form2.Show();

The problem seems to me to be when I handle the FormClosing and set e.Cancel = true. I don't know what is going on behind the scenes to manage the list of windows that show up in the menu. I can call Hide() on form2 from its parent window, form1,and when I use the control to show form2 again it shows up in the window list as I would expect.

Anyway, thanks for the quick response.

How to save page as MHT with ASP/C#

Hey guys, I'm having a hell of a time trying to figure out how to save the current web page as an MHT from within my current asp application.

Basically, I want to do THIS (see link), but have it work under C# (not C++).

http://www.codeguru.com/cpp/i-n/ieprogram/article.php/c4397/

It doesn't like ANY of the commands, it says the directives are all wrong.

For what it's worth, I have MSADO15.DLL added as a reference.

Thanks,

Todd

Hello folks.

I am writing an application which has two text boxes (call them A and B). B is a hexdump representation of the text in A. So far, so good. What I want that when text is selected in A the corresponding hex characters are highlighted in B, and vise versa.

I started with TextBoxes, but I needed to know when the selection in one box changed and TextBox doesn't tell you this. RichTextBox has the SelectionChanged event - perfect - so I switched to RichTextBoxes.

But now, whenever my selection extends beyond a space, RichTextBox starts selecting the entire word(s). I can't get it just select what I drag the cursor over. I have checked the AutoWordSelection property and it is set to false - I even checked it at runtime to see if had changed, but it is false at the moment my selection is being changed.

Does anyone have any ideas? Can this #!&^ "feature" be turned off in RichTextBoxes? Or can I go back to TextBoxes and get notification of a change to the selection?

Hi Clive,

I dont think you can change the selection mode the way you want it.

Even Wordpad does it like that: as soon as a selection crosses a word boundary, it extends to contain complete words only (so not only with spaces, try e.g. a period).

And yes I too dislike that.

Read config file with OpenExeConfiguration? [modified]

Hello. Right now I admit defeat and don't know how to do this. I have a configuration file that I have to load at runtime and interpret. This works fine for all the settings in the appSettings sections but I don't know how to get the value from the system.diagnostics section.

This is an example of an config file (in "real" a lot bigger;))

<configuration>
  <appSettings>
    <add key="Hello" value="World" />
  </appSettings>
  
  <system.diagnostics>
    <switches>
      <add name="Trace" value="4" />
    </switches>
  </system.diagnostics>

</configuration>

To load the file I use the OpenExeConfiguration method and most of the data I can get to, but not the "Trace" value from the system.diagnostics.

<code>// Get the configuration file.
System.Configuration.Configuration config = ConfigurationManager.OpenExeConfiguration("c:\\projext1.exe");

MessageBox.Show(config.AppSettings.Settings["Hello"].Value);  //this shows OK

ConfigurationSection sel = config.Sections["system.diagnostics"]; // Here I find the section, but then...  ???
</code>

Does anybody have any idea on how to get the value? A possible solution might be to load the file into XML, but I'm still hoping on using the Configuration object. Hope you can stand my bad english and thanks to enybody that have a suggestion.

Edit: formatting... Sigh | :sigh:

Be sure that you are: using System.Diagnostics
Then, in your code, you can use the configured switch by creating a TraceSwitch with the same name as in your config file:
TraceSwitch appSwitch = new TraceSwitch("Trace", "");
The value you want to retrieve is appSwitch.Level (which in your case will be Verbose, as you have the value set to 4 in your config file.

Graphing in C#, Possible?

gvanto8-Jan-07 8:04

8-Jan-07 8:04

I would like to draw a graph of a vector of float values and was just
wondering if this is possible in C#?

Basically, just being to draw lines (by giving it co-ordinates) would suffice, however,
have the capability to draw a vector (graph plotting) would be ideal...

Any help much appreciated!

hi Gerry,
Vector/advanced graphics is supported in Framework 3.0. if you are working with 1.1/2 version of the framework, this should be helpful

Look up the System.Drawing namespace. In the Graphics class you will find methods for drawing any shape you like.

I think what he is referring to is creating your own custom control that will draw the graphics how you want using the Graphics object provided in the OnPaint method of UserControls.

Yeah absolutely right Thomas,

For example, I'd like to have something like:

<br />
double [] dblArray = new double[5];<br />
<br />
//Here populate dblArray with say: {0.30, 10.45, 23.61, 10.20, 57.10}<br />
<br />
<br />
//Plot the array with: (plotting ie. joining the points)<br />
PlotArray(dblArray);<br />
<br />

Any ideas on how to start with PlotArray( ) ?

Thanks for the help guys, much appreciated!

Then you need to get MSDN fixed where you live since it is an invaluable resource for windows developers.

The best way to start is to look at the documentation for the Graphics class we are telling you about.
