There is a question about run dotnetframework1.1 application and dotnetframework2.0 application at the same time.
Is anybody tell me the solution for this? Thanks very much!
OS: Win2003 64bit

If you have web application deployed on IIS,then every virtual directory should be mapped to corrrect version of ASP.NET ISAPI exetention.You can configure it by aspnet_regiis.exe.So every Virtual directory will run on 1.1,and for 2.0,you also need to register it,after registering it you'll get dropdown for ASP.NET version in the properties of your Virtual Directory and selecting ASP.NET tab.
Cheers!!

The server's OS is Win2003 64bit
Installed dotnetframework1.1(32bit) and dotnetframework2.0(64bit).
There has no ASP.NET choose in IIS.

Its means you have installed IIS after .NET Framwork.
If you want this, From the command prompt , go to Framework Directory
e.g : c:\windows\microsoft.net\Framework\V2.05732
then run aspnet_regiis Command 
cheers,

I reinstall the .NET Framwork1.1(32bit) and .NET Framwork2.0(32bit) by aspnet_regiis.exe -i
But also have no the ASP.NET option.

As you said,OS is 64 bit.So install the 64 bit framework,32 bit wont work

Hi again. I have another question hopefully someone can help me with. I've found articles online where it is said that an Interface does not have a GetType() function as it is not derived from 'Object'. This seems true since when trying to work with the IDataObject interface, there is no GetType() function.
The problem is, as my last post addresses, I'm trying to change code from C# to VB for drag and dropping from Outlook. The original C# code is shown below. The very Odd thing I don't understand is how in C# GetType() works with IDataObject. Inside the DragDrop event of an Windows Form object e.Data.GetType() is usable, but this is not the case in VB.
I have the below code converted to VB but the New constructor does not work since there is no GetType() functions "visible."
Thanks again!!
private System.Windows.Forms.IDataObject underlyingDataObject;
private System.Runtime.InteropServices.ComTypes.IDataObject comUnderlyingDataObject;
private System.Windows.Forms.IDataObject oleUnderlyingDataObject;
private MethodInfo getDataFromHGLOBLALMethod;
public OutlookDataObject(System.Windows.Forms.IDataObject underlyingDataObject)
{
this.underlyingDataObject = underlyingDataObject;
this.comUnderlyingDataObject = (System.Runtime.InteropServices.ComTypes.IDataObject)this.underlyingDataObject;
FieldInfo innerDataField = this.underlyingDataObject.GetType().GetField("innerData", BindingFlags.NonPublic | BindingFlags.Instance);
this.oleUnderlyingDataObject = (System.Windows.Forms.IDataObject)innerDataField.GetValue(this.underlyingDataObject);
this.getDataFromHGLOBLALMethod = this.oleUnderlyingDataObject.GetType().GetMethod("GetDataFromHGLOBLAL", BindingFlags.NonPublic | BindingFlags.Instance);
}

Hi David,
I am having the same problem, I can get the oleUnderlyingDataObject ok but I am unable to get the method getDataFromHGLOBLAL.
The last line of code returns nothing...
Did you find a resolution to this?
Regards
Bill Terrington
Public Sub New(ByVal underlyingDataObject As System.Windows.Forms.IDataObject)
'get the underlying dataobject and its ComType IDataObject interface to it
Me.underlyingDataObject = underlyingDataObject
Me.comUnderlyingDataObject = DirectCast(Me.underlyingDataObject, System.Runtime.InteropServices.ComTypes.IDataObject)
'get the internal ole dataobject and its GetDataFromHGLOBLAL so it can be called later
Dim innerDataField As FieldInfo = CType(Me.underlyingDataObject, Object).[GetType].GetField("innerData", BindingFlags.NonPublic Or BindingFlags.Instance)
Me.oleUnderlyingDataObject = DirectCast(innerDataField.GetValue(Me.underlyingDataObject), System.Windows.Forms.IDataObject)
Me.getDataFromHGLOBLALMethod = CType(Me.oleUnderlyingDataObject, Object).[GetType].GetMethod("getDataFromHGLOBLAL", BindingFlags.NonPublic Or BindingFlags.Instance)
End Sub

Sorry but I never did find the solution. Not sure if you are using the same code I was (Providing for drag and drop from Outlook)?
I ended up using the original C# code and creating a C# library that my VB program referenced.
Then I ended up using an online code converter and now the program is in c# anyway...
Sorry couldn't be more helpful.

I have already created a c library but was hoping to avoid
the overhead if possible.
Thanks for the reply anyway.

Translate C#:
FieldInfo innerDataField = this.underlyingDataObject.GetType().GetField("innerData", BindingFlags.NonPublic | BindingFlags.Instance);
TO VB:
Dim innerDataField As FieldInfo = CObj(Me.underlyingDataObject).GetType().GetField("innerData", BindingFlags.NonPublic Or BindingFlags.Instance)

Thanks Fred. Although it certainly has been awhile since I posted that. Where were you then!?
hahaha. Just a joke.
When I couldn't figure it out I ended up using a .NET library to keep the C# code as it was. Then as it turned out, because I needed more C# experience, I ported my program over to C# and didn't need the code in VB anyway.
All kidding aside. Great work.

Hello. I am trying to implement drag and drop in my application (from Outlook messages and message attachments) I found the code on a Code Project post, but it is for C#. My application is written in VB, so I'd rather convert the code to VB than add a required DLL to what my program requires.
I need help with the below lines of code. Where I need help is at the CreateStream function for example. I cannot find a equivalent for the "return" section of "[return: MarshalAs(UnmanagedType.Interface)]"
Can you help me?
Thanks.
[ComImport, InterfaceType(ComInterfaceType.InterfaceIsIUnknown), Guid("0000000B-0000-0000-C000-000000000046")]
public interface IStorage
{
[return: MarshalAs(UnmanagedType.Interface)]

Hi! I'm using a Windows form user control in a Vb6 application. I'm having some problems while using the control in Vb6 application.
1. I'm not able to set the value of a combo box in the user control programmatically. i.e At the run time I'm running some code which is not setting the value of the combo box in the Vb6 form.
2. When I click on some Vb6 control on the form then user control gets hidden. I'm adding the user control dynamically at run time.
3. Some module level variable were not able to retain there values in the user control but when I changed them to "Shared type" they were able to retain their values. Similarly progress bar is not able to retain its property values.
I tried searching on the net but could not find any suiable solution.Any kind of help is appreciated.
Thanks

What does this have to do with the .NET Framework?
only two letters away from being an asset

This is related to InterOp and I could not find any forum specific to Interop here so I put it in the dot net framework.

I am devloping an application in which I wan to bind gridview using xml data which comes from database ..
How can I bind the gridview using SqlAdapter and dataset objects ?
I have following code but it doesnt make column as per xml data in grid view
It shows all data into single column ..
I dont know whether I am make some mistake in inserting or retrving the data...
Whether I have to store the xml as document type or as storage type ?
I have following code which I use to bind the grid view ...
Dim sqlString As String = "Data Source=ADSERVER\..........."
Dim sqlConnection As New SqlConnection(sqlString)
Dim xr As Xml.XmlReader
Dim ds2 As New DataSet
Dim dt As DataTable
sqlConnection.Open()
Dim cmd As New SqlCommand("Select data from xmlTest where PKID=63", sqlConnection)
xr = cmd.ExecuteXmlReader()
ds2.ReadXml(xr, XmlReadMode.InferSchema)
dt = ds2.Tables(0)
VGridControl1.DataSource = dt
Which displays the in the single column as it is in database...

Have you checked you dt,That it is having single column as DB or according to your XML schema?
Cheers!!

I have xmltest table in datatbase and the data column which has the xml datatype
but I have a code of reading the xml data as follows
conn.Open();
SqlCommand command = conn.CreateCommand();
System.Text.StringBuilder builder = new
System.Text.StringBuilder();
command.CommandText = "SELECT XmlDesc FROM XmlTest WHERE ID = " + ID.ToString();
SqlDataReader reader = command.ExecuteReader();
if (reader.Read())
{
1)how to use in vb.net ?
-----> SqlXml sqlXmlValue = reader.GetSqlXml(0);
XmlReader xmlReader = sqlXmlValue.CreateReader();
while (xmlReader.Read())
{
2) How to use in vb.NET
---> builder.Append(xmlReader.ReadString());
builder.Append(" ");
}
txtXmlDesc.Text = builder.ToString();
}
else
txtXmlDesc.Text = "No Value";
now I want to convert this code in to vb.NET
what shoud I use at 1 and 2 ?
insted of SQLXml which is in c# what should I use in vb.net ?

SqlXml is a .NET class not specific to C#. IMO stick with C#, VB is dead and VB.NET is a poor attempt to keep VBers relevant.

I am trying to set a no. of pictureboxes containing an image( image being a transparent image) of its own. Is there any way to set these pictureboxes over one another so that the image of one picturebox below another picturebox can be seen( as the images set over them are transparent)????
|
|
|
|
|
You can't do this with pictureBoxes - even though the image contains transparent areas, the pictureBox will only show the background colour of the parent control (or anything you paint manually in the PaintBackground event of parent control). You may have better luck doing the painting yourself rather than relying on pictureBox - this will give you more control over what happens when you layer images like this.
