Could you specify a little clearer what you are looking for?

Are you talking about actual dictionaries, with words and explanations or translations?
Or are you talking about the Dictionary class...?

Visual Studio can't evaluate this, can you?

public object moo<br />
        {<br />
__get { return moo; }<br />
__set { moo = value; }<br />
}

Showing a "Image" in a Datagrid

Hi all,

I am trying to show a "Image" in a DataGrid.
I have a new class I created that has 3 properties that are string and one that is of type image.
I create an Array of this class, and make the DataGrid source the Array.

But the image column comes up as a red cross in a white background, i.e. its not an image.

Can anyone give me some idea of best practice to show an image in a DataGrid please?

Regards

Tony

Hi Tony,

hope the following code works.

private void DataGrid1_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
System.Web.UI.WebControls.Image anImagine ;
if(e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item )
{
anImagine = ((System.Web.UI.WebControls.Image)e.Item.Cells[1].Controls[1]); anImagine.ImageUrl="icons/" + e.Item.Cells[0].Text.ToString() + ".gif";
}
}

When you create strings special characters require an escape sequence. Any unicode character can be escaped by using \u and the unicode value, \uFEFF is one I am using because of some pdf issue. Newlines are \n tabs are \t a \ is \\.

Transfering values (Global variable)

Good evening everyone,
I have a feeling it's a silly question Unsure | :~

but how can you transfer a variable from one object to another without having to create another instance of these objects.. say I have two open forms and I want to pass a value entered in one form to the other one.

Thanks a million Rose | [Rose]

If you decalre a member as public static, you don't need an instance to access it.

As an example, if you declared a string in class like this:

public sealed class MyGlobal
{
    public static string MyString = null;
}

You could access it from anywhare in your project like this:

MyGlobal.MyString = "hello";
MessageBox.Show( MainForm.MyString );

Hope this helps.

If the variable is a reference type, you won't be creating a new instance, you will simply be passing a reference to the existing object. If the variable is a value type, you can pass it as a reference:

...

int someVarIWantToPass = 0;
form2.PassVarByRef(ref someVarIWantToPass);

...

TcpChannel Remoting - Proxy Possible?

I found a bit of code that allows you to add a webproxy to an HttpChannel
(http://dotnetjunkies.com/WebLog/chris.taylor/archive/2004/01/24/6050.aspx)

but even this approach would not work for TcpChannel. Is there some other way to implement a proxy functionality on a tcp channel?

Well, maybe you should look at custom sinks ... just an idea .. I'm not sure at all here WTF | :WTF:

I've used sinks, but to my knowledge the last sink on the client side is the Transport Sink, and that cannot be customized or overridden.

Does anyone know how to concat on the displaymember of a combobox? I am trying to contatenate two fields together. Here is my code.

cboLocation.DataSource = ds;
cboLocation.DisplayMember = (string.Concat("Locations.LocationName", ' ', "Locations.LocationNo"));
cboLocation.ValueMember = "Locations.LocationNo";

When I did this, only the Locations.LocationNo shows. Need help.

what is your data source , if you are executing a query against a db , simply change your query to select Locations.LocationNo , (Location.LocationName + ' ' + Location.LocationNo) as LocationName from Locations

ProgressBar Marquee does not scroll

Thank you very much for reading and helping me.

I am now working with my degree final year project. I want to use a progress bar with style set to marquee to show a progress. However, I found that the progress bar does not scroll while I am running my project.

I have tested in a new project with only putting a progress bar with style marquee. It works smoothly. On the other hand, even if I new a form in my working project (the FYP one), and just putting a progress bar on it, it still cannot work. I also found that the appearance of the progress bar is flatten just like a disabled textbox.

May I know is there anything I have set it wrong?
I am new with C#. Thanks a lot for guiding me!

Thank you Zoltan. I guess that I did not include EnableVisualStyles() before newing the form.

I tried this and the progress bar did run.

I wonder why it does not need to enable visual style if I put a progess bar with marquee as style in a brand new project. D'Oh! | :doh:

Because, by default, EnableVisualStyles is already turned on. Start a new Windows Forms project, then open the Program.cs file and you'll find it.
