Is it correct to create a struct that is nested within a class e.g.
public partial class _Default : System.Web.UI.Page
{
protected struct SupportStruc
{
protected string var1
protected string var2
}
SupportStruc supporter = new SupportStruc();
protected void Page_Load (..) {
supporter... //var1 and var2 are not displayed here...
}
}

It's neither correct nor incorrect.
I try to limit nested types to private types only used from within the outer type, and you'll find that the .NET Framework has only very few public nested types.

Thanks, I agree with that, as a matter of fact I wanted to use the inner struct from the outer class. The problem is that Intellisense did not display any of the fields of the struct...

I want to control some hardware by internet. In order to do that I want to use ASP.NET and C# language. Suppose I want to turn on a LED which is placed in a PCB board. That PCB board is connected to a computer which has internet connection. From remote distance I will do some thing so that that LED will be turned on. If any body know some things abut the above meter please inform me as soon as possible.

ASP.NET does not do that. To do this inside the browser, you would need an activeX control. Unless the LED is on the server, then it's easy.

As nicely and truely said by Christian, you have to use activex control with in your asp.net page which itself will take care of the interaction with the hardware. So whatever code you want to write to controll the hardware, have to be written inside the activex control. Your asp.net page will only call the methods that you have defined in the activex control to maintain hardware. This is not an easy job though but there is nothing called impossible. So all the best.

Hi,there
Here is my case, we are developing a Web application for a client. By now everything else is fine, except a map issue. What client want is when adding a company record in the system, the company's address needs be typed, but except that, client have offered an image of their city in Photoshop file format. Client want the address can be roughly reflected on the image.
That is they can zoom, pan the image to the location according to the address (address data is not assocated with image in this case, they really just want some simple manipulation), and do some mark on the image and return as a hyperlink something, so next time when they view a company record, the click the link, system can bring the image out and go to the mark which corresponding to the
company's address.
So as you can see, it's not a strict GIS or map application, but it still need lots of image, graphic, map manipulation. I have looked at Google map, Sharpmap, however, given the system budget and timeframe, I don't think they could be applicable in this case.
I'm thinking to get some image or map manipulation library and develop an in-house function for this system, and spend about 1-2 weeks time(although they want it in one week). If anyone who can offer some ideas, advice, suggestions, that'll be greatly
appricated.
Cheers.

Hello, I build an ASP.NET 3.5 Website.
I have a registration form that has an email address field,
I use SQL Server 2005 to storethe Data.
I would like to know how can I validate if the email address is already in use or not instantly during the registration process.
I'm looking forward to hear from you soon.

execute
select * from tableOfTheTable where EmailId='EmailIdYouAreAboutToSave'
if this query result is 1 row, that means that emailID is already in use and is stored in DB.

I need ajax implementation for tab strip control in my asp.net web page. the first tab contains some input controls and only when the user enters values into the first tab then the next tab to be active and so on. the user should be able to edit fields in previous tabs but should not be able to go to next tab before completing the current tab.
|
|
|
|
|
are you using atlas tab strip control..
If so, then just place it inside one UpdatePanel... thats all.
|
|
|
|
|
You have to use JavaScript validation in order to check whether the required data is filled or not and make the next tab active.

Hi, after some hours dealing with the above error message, i am afradid need help on this:
i have a DetailsView control, inside it i have some templatefields, one of them is a radiobutton list.
When, in Edit mode, the user changes the radiobutton seleccion (onselectedindexchanged = "RefreshDropDownList"), i need to recharge another templatefield wich is a DropDownList, with new values on it. The DropDownList is bounded to some ObjectDataSource and my purpose is "swap" to anthoer ObjectDataSource when the user changes the RadioButtonList selection.
The method RefreshDropDownList is:
protected void RefreshDropDownList(object sender, EventArgs e)
{
if (((RadioButtonList)sender).SelectedValue == "1")
{
if (odsAreasCU.SelectMethod != "GetAreasPubProyecto")
{
DropDownList ddl = ((DropDownList)dvCU.FindControl("DropDownList20"));
ddl.DataSourceID = odsNewObjetDataSource.ID;
ddl.DataTextField = "Name";
ddl.DataValueField = "CodObj";
ddl.DataBind();
}
}
else
{
}
}
When it passes over "ddl.DataBind();" line, a green arrow exception arises with the following message:
'DropDownList20 has a SelectedValue which is invalid because it does not exist in the list of items'
DropDownList20 is the one on this aspx page code:
<asp:TemplateField HeaderText="Area" SortExpression="Area">
<EditItemTemplate>
<asp:DropDownList ID="DropDownList20" runat="server" DataSourceID="odsAreasCU"
DataTextField="Nombre" DataValueField="CodObj" ForeColor="#006666"
SelectedValue= '<%#DataBinder.Eval(Container.DataItem,"Area")%>'
Width="200px" ondatabinding="DropDownList20_DataBinding"
ondatabound="DropDownList20_DataBound"
onselectedindexchanged="DropDownList20_SelectedIndexChanged1"
AppendDataBoundItems="True">
<asp:ListItem Value="0">(sin área específica)</asp:ListItem>
</asp:DropDownList>
</EditItemTemplate>
Any help or suggestion on this would be appreciated, i am really dissapointed with this bug.
Greetings.

Hi,
If you are trying to use the selectedvalue proeprty and the selected value does not fall with in the available value colections in the drop-downlist then you will get this error. It is preferred to insert the value in the drop-down list if it does not exist. Just check the sample code:
if (DropDownList1.Items.FindByValue("Gurgaon") != null)
{
DropDownList1.Items.FindByValue("Gurgaon").Selected = true;
}
else
{
DropDownList1.Items.Add(new ListItem("Gurgaon"));
}
I hope it helps.
