Hi,
You can use like this.....
CShort(str) => (short)str;
* str = any var. or exp.

Im not sure if (short)str works for - lets say a string.
Better use Convert.ToInt16(str)!
( So I tried:
<br />
string str = "22";<br />
short s = (short)str;<br />
with C#3 and this will not even compile! (As I thougt - you can't cast a string to a short - and before you bother: some types have inbuild implicit cast operators to handle those situations!)

System.Convert.ToInt16 is the closest equivalent.
In general, the System.Convert methods are closer to how the VB conversion macros work than the 'hard-core' C# casts.
The C# casts are closer (but not identical) to VB's DirectCast.

I want to display color with corresponding color name in combo box.In my program i used for this image list.In that i stored bmp images.But i want to display color name also.How i do that .My code is
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim items(Me.ImageList1.Images.Count - 1) As String
For i As Int32 = 0 To Me.ImageList1.Images.Count - 1
items(i) = "Item " & i.ToString
Next
Me.ComboBox1.Items.AddRange(items)
Me.ComboBox1.DropDownStyle = ComboBoxStyle.DropDownList
Me.ComboBox1.DrawMode = DrawMode.OwnerDrawVariable
Me.ComboBox1.ItemHeight = Me.ImageList1.ImageSize.Height
Me.ComboBox1.Width = Me.ImageList1.ImageSize.Width + 18
Me.ComboBox1.MaxDropDownItems = Me.ImageList1.Images.Count
End Sub
Private Sub ComboBox1_DrawItem(ByVal sender As Object, ByVal e As System.Windows.Forms.DrawItemEventArgs) Handles ComboBox1.DrawItem
If e.Index <> -1 Then
e.Graphics.DrawImage(Me.ImageList1.Images(e.Index), e.Bounds.Left, e.Bounds.Top)
End If
End Sub
Private Sub ComboBox1_MeasureItem(ByVal sender As Object, ByVal e As System.Windows.Forms.MeasureItemEventArgs) Handles ComboBox1.MeasureItem
e.ItemHeight = Me.ImageList1.ImageSize.Height
e.ItemWidth = Me.ImageList1.ImageSize.Width
End Sub
Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
Select Case (ComboBox1.SelectedIndex)
Case 0
TextBox1.ForeColor = Color.Red
Exit Select
Case 1
TextBox1.ForeColor = Color.Yellow
Exit Select
End Select
End Sub
End Class
When i add the following code in combobox1_Drawitem
e.Graphics.DrawString(items(e.Index), Me.Font, Brushes.Black, e.Bounds)
It is not working bcs when i set a color name in items(e.index))it is common to every image.How can i solve this problem.

Hi all,
Does VB.Net 2003, Supports XML Commenting. I tried this Function But it is not giving the desired output
'''<summary><br />
'''Function To make Connection to SOL server and Return the SQL Connection<br />
'''</summary><br />
'''<param Name="sServerName">The ServerName to be connected</param><br />
'''<param Name="sDataBaseName">The DataBase to be connected</param><br />
'''<remarks><br />
'''If the Function Succeeds it will return the Connection , Else it will return nothing<br />
'''</remarks>
Thanks
Dana

No in VS2003 only C# supports XML-Comments.
VS2005 supports those in VB.net too.

Thanks for the reply CKnig
Oh God.Any other Way ?

Hmm.. maybe there is some way by adding code-attributes to the methods but I don't know exactly which.

Not out of the box, but there's an add-in that provides the functionality. It's called VB Commenter and was part of Powertoys for VS 2003. However, it seems to be rather difficult to locate now. It's not clear whether it's contained in this:

I want to display color image with corresponding color name in combo box.I got to display color in combobox not corresponding color name.
The code is
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim items(Me.ImageList1.Images.Count - 1) As String
For i As Int32 = 0 To Me.ImageList1.Images.Count - 1
items(i) = "Item " & i.ToString
Next
Me.ComboBox1.Items.AddRange(items)
Me.ComboBox1.DropDownStyle = ComboBoxStyle.DropDownList
Me.ComboBox1.DrawMode = DrawMode.OwnerDrawVariable
Me.ComboBox1.ItemHeight = Me.ImageList1.ImageSize.Height
Me.ComboBox1.Width = Me.ImageList1.ImageSize.Width + 18
Me.ComboBox1.MaxDropDownItems = Me.ImageList1.Images.Count
End Sub
Private Sub ComboBox1_DrawItem(ByVal sender As Object, ByVal e As System.Windows.Forms.DrawItemEventArgs) Handles ComboBox1.DrawItem
If e.Index <> -1 Then
e.Graphics.DrawImage(Me.ImageList1.Images(e.Index), e.Bounds.Left, e.Bounds.Top)

Select Case (ComboBox1.SelectedIndex)
Case 0
TextBox1.ForeColor = Color.Red
Exit Select
Case 1
TextBox1.ForeColor = Color.Yellow
Exit Select
End Select
End Sub
 How i display corresponding color name in that combo box.

well - you managed to show the images .. the text is much simpler. Just add the following line just after your e.Graphics.DrawImage line:
<br />
e.Graphics.DrawString(items(e.Index),me.Font,Brushes.Black,e.Bounds)<br />
(didn't test it so there might be a typo but I guess you get the idea)
BTW: you should but handle the case where the current cell is focused - normaly you use the e.DrawFocusRectangle() but this is not the way here - maybe just draw a shading (with an almost transparent brush) over your picture?

I cant get .In Imagelist i used bmp image to set that color.When i typed the code that u given.Its not worked.Pls help me
|
|
|
|

sorry - did miss the problem with the items-list
you need to declare this not as a local variable in the constructor but as a private class field.
BTW: if you would say what error message you get we could help you better

Hi,
I want to encrypt a string in a text field and decrypt the value and display in another text field. Can anyone provide me a code for this in vb.net. Thanks in advance..
|
|

|

Have a look at the "System.Security.Cryptography.RijndaelManagedTransform" class.
The MSDN-help will provide you with infos and examples how to use this.

Hi,
The simplest method of doing this is change the asci value of each character in the string to encrypt and to decrypt string convert acsi to its orignal value.
Hope this helps![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)
