Re: C#: how to get estimated download time

You estimate it based on how much you still need to download, and how much you're getting per second.

DoDragDrop and MouseClick event

Hi All,

I'm implementing drag/drop in my windows forms 2.0 / c# application.

In my control's MouseDown event handler, i'm calling DoDragDrop appropriately. But, the call to DoDragDrop seems to prevent other mouse events (MouseClick, DoubleClick, etc) from firing.

Is there a way round this? I need to be able to distinguish between a mouse-down drag starting event and a double click.

Thanks

I was doing something similar to what you are doing using DragDrop for a TreeView control and trying to use Click, Double Click, etc. and I found no way around it.

Hope this helps

Hi Mike,

Thanks for your post. If you're interested, i found the solution.

You're not supposed to call DoDragDrop from the MouseDown event. Instead, you should use the mousemove event, and call DoDragDrop where the L button is down and the mouse has moved outside of the rectangle centered around the point that the mousedown happened, of size SystemInformation.DragSize.

This example http://msdn2.microsoft.com/en-us/library/system.windows.forms.control.dodragdrop(vs.71).aspx[^] demonstrates the method perfectly.

I hope that helps you.

Is there any possibility to enable scripting in internetexplorer using c#

Thanks In Advance

Christian Graus17-Apr-07 23:58

You mean via ASP.NET, or when you have a client app running on the target machine ? If the latter, then perhaps, but I doubt it. If the former, then, no way. Your C# code is never going to run on the client.

Thank you for that response.My problem is i have to navigate to a link in a new browser on click of an image, code for that in page_load event like

strURI = window.open('test.aspx',null,'location=yes',null)
"imagebutton.attrubutes.add("OnClick",strURI)",

if the java script is disabled in the browser how to achieve this?

Thanks In Advance

I am not usig ASP.NET but from my experience with php I can say this:

You have two solutions. The first is to generate the web page as shown to the user in the server. In the generated page, avoid using JavaScript, but create hard coded links.

The second solution is to detect that JavaScript is blocked (I am sure you can find the techniques on one of the many JavaScript sites) and kindly ask the user to switch JavaScript on.

Fortunately you cannot switch JavaScript on at the server side. This would cause a serious security leak for clients that chooses to block JavaScript. I think this is a reason why server side scripting is far more attractive than client side scripting.

The best way is to build your link the normal way, with a button or anchor tag.

Hi all, I have a .net remoting system (server, client and remotable object). Now I need the client to be able to call a remote object method passing an object by reference as a parameter. That object is a class written by me and inherits from MarshalByRefObject, but I don't know how to set the configuration file: it keeps giving me security exceptions... The examples found over the internet didn't help me much. Someone could help me?

The actual exception message is:
System.Runtime.Serialization.SerializationException: Because of security restrictions, the type System.Runtime.Remoting.ObjRef cannot be accessed. ---> System.Security.SecurityException: Request failed.
at System.Runtime.Serialization.FormatterServices.nativeGetSafeUninitializedObject(RuntimeType type)
at System.Runtime.Serialization.FormatterServices.GetSafeUninitializedObject(Type type)
...

Thank you,
Alessandro

Composite control error - need expert help

I imagine if you googled, that would be the most common regex example on the web.

aspx is irrelevant, regex is regex.

Hi to all,

I develop a composite & users control that contains class and struct in a collection.

when i try to put values in them i get error in design mode but the control works fine when executing the project.

how can i fix it? i think it has to do with the attributes but i dont know excactly.

here is the code of the control

1 [DefaultProperty("ColumnName")]
2 [ToolboxData("<{0}:PanelForm runat=server>")]
3 public class PanelForm : Panel,PoentaListBasic
4 {
5 List _executeParam;
6 public List ExecuteParam
7 {
8 get
9 {
10 if (this._executeParam == null)
11 {
12 _executeParam = new List();
13 _executeParam.Add(new ControlParam(this.SqlParameterName, this.SqlParamType, this.SqlParamSize, this.ColumnValue, ParameterDirection.Input));
14 }
15
16
17 return _executeParam;
18 }
19 set
20 {
21 if (_executeParam == null)
22 _executeParam = new List();
23 _executeParam.AddRange(value);
24 }
25 }
26 }

1 public struct ControlParam
2 {
3 public ControlParam(string paramName)
4 {
5 this.paramName = paramName;
6
7 }
8
9 string paramName;
10 public string ParamName
11 {
12 get
13 {
14 return paramName;
15 }
16 set
17 {
18 paramName = value;
19 }
20 }
21 }

the error in the design says:

Error Creating Control - fieldPnl

Cannot create an object of type 'System.Collections.Generic.List'1[[ControlParam, Dal, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]' from its string representation '(Collection)' for the 'ExecuteParam' property.

and this is what i see on the page containing the control

<po:PanelForm runat="server" ID="fieldPnl" ExecuteParam="(Collection)" >
