Include a reference to his assembly in your project and then do the following:

ExpressionEval eval = new ExpressionEval(txtFunction.Text);
object output = eval.Evaluate();
if (output != null)
{
  // You have your answer. Do what you want with it.
}

Populate outlook and outlook express new email with HTML content from winfom

hello all,
I need an example how to populate outlook and outlook express with html body.
The user can edit the mail within his client before submission.

The scenario would be like this:
====================================
1. In winform configuration the user will define his mail client.
outlook or outlook express
2. On winform user will click send mail.
3. New mail form of the user client will popup, filled with :
from: , to: and the messaqge body populated with html rendered at winform.
4. While new mail client is open, the user can edit the mail message and the submission action will be triggered by the user.

Thanks
Tsachi

Hi to all!!!
I have a class & in constructor I call for "webBrowser = new WebBrowser();"
There I get thread state exception (ActiveX control '8856f961-340a-11d0-a96b-00c04fd705a2' cannot be instantiated because the current thread is not in a single-threaded apartment.).

The interesting thing is that the first time i call that class no exception is made.
Then I destroy that instance and make a newone that throws exception.

I use that class for some gdi+ stuff, I also use background worker.

thx

Hi,

I suggest you create all WebBrowser instances in the main or GUI thread.
Since your class constructor contains "new WebBrowser()" it too should only be instantiated
by the main thread, not by a BackgroundWorker thread.

datagridview checkbox field [modified]

There is a checkbox field in the datagridview control.
In the datagridview_cellclick() event I have a condition so that the user is allowed or not allowed to check this box.
Not sure why this does not seem to have any affect because the condition is met correctly but when the grid is populated then the checkbox does indeed appear as if the if statement has no affect.

This is what I am doing in the cellclick event
And there is nothing else that makes that field to have a check in the checkbox field.

if...
...
dgvSecurityPricing.Rows[e.RowIndex].Cells["Price"].Value = false

Not sure why in _CellFormatting event this gets set to true

Thanks

I doubt you can easily, why would you need to ? Isn't it mostly for reading different formats ? Which ones does it support that GDI+ doesn't ?

I what to serialize a class with Static Variables. But the Static variables are not serializing.

{
String fP = "\\SerializClass.txt";
Stream file = File.Open(fp, FileMode.Create);

SessionManager SM = new SessionManager();

IFormatter formate = (IFormatter) new BinaryFormatter();

Formatter.Seralize(file,SM);
file.Close();
}

SessionManager Class :

Clas SessionManager
{
SessionManager
{
}
Public Static String Name;
Public String RollNo
}

Here I can get the RollNo when I deseralize the file but not Name.

Plz Help me in Seralizing the Static Variables also .

You are serialising the instance of the class, but the static variables are not instance members, they are class members.

You can't serialise a class, as you can't create a class by deserialising. You can only serialise an instance of a class.

Hi all,
My question is very simple;
I have two arrays :

double[] arr1 = new double[] {1,2,3};<br />
double[] arr2 = new double[] {10,20,30};

I want to store to and than read these arrays back from an XML file.
Could someone please send a small piece of code written in C#.

Thanks.
Cengiz EKEN.

You're not going to believe this, but I spent 15 minutes writing code, and it got lost.

Basically, you can store the array as a string, use the Split method and double.TryParse to find the values, and I'd be putting them in a list, and create a list of lists.
