Hi there!
I have a COM dll built in VC++ 6.0, and I use it in a Web application written in VB.NET. I'm having some strange problems, throuing some exceptions and other things...
I suspect the COM dll, but I just can't figure why. If I use it from a regular windows application it seems to work fine, no problems.
So, I was think if there is a way to debug into the COM from the WEB app I could see some more things. Does any one knows how to do it, or have any suggestion for my problem?
Thanks for you time.

Hey all,
I'm trying to get an application up and running using Master Pages and their content pages using events to check user input. The problem that I'm encountering is how and where to declare the events so they fire just within the page that is accessed and its master page.
I've used events before but not with master pages, ie: all content pages are aspx pages. Is it necessary to create seperate classes to handle the interactivity with the events, and if so how do I interconnect them with the content pages?
The data I've come across on Google is very generic so far and handles only one master page with one content page. I only have two master pages, but it is running me through the ringer trying to figure this out.
I know that this jumbled question probably sounds like the ravings of a simpleton, but if y'all could give me a push in the right direction I would really appreciate it.
Thanks in advance.

To access master page controls from the content page do something like this.
<br />
protected void Page_Load(object sender, EventArgs e)<br />
{<br />
this.Init += new EventHandler(Page_Init);<br />
}<br />
<br />
protected void Page_Init(object sender, EventArgs e)<br />
{<br />
DropDownList ddl = (DropDownList)this.Master.FindControl("ddl");<br />
ddl.SelectedIndexChanged += new EventHandler(ddl_SelectedIndexChanged);<br />
}<br />
protected void ddl_SelectedIndexChanged(object sender, EventArgs e)<br />
{<br />
}<br />
|
|
|
|
|
Does this mean that I declare the event delegate on the master page?

No, thats not necessary. You just add the event in the content page.
|

Before my next question let me first thank you for all the help you've given me thus far, I do appreciate it.
When I've used events before I had to add classes that handled the event information ie: Custom data Classes, EventArgs, and Custom Handlers. Is this still necessary with the above declaration?
<edit>
I can provide code samples if it'd help.

You are attaching the delegate to the event with the += operator. Does that answer your question?

|
|
Yes it does thank you.

You have to add it to the Controls collection on the page.

Hello,
Thank you for your reply. I know it's simple. But it is not working when I add.
Page.Controls.Add(panel)
to the above page.
Please, send me a working one.
Thank you

You originally said "I am using ASP.NET 2.0. I am trying to add textBox programmatically."
So, why did you add the panel? You should add the text box.

Hi, I am creating a forum type. This forum consists of many sub forums in it for example: Computers, Gadgets, Music etc.... Users will login to use this forum for their own use of trading objects and bidding on object. The problems I am facing right now that I don't know are these:
1. I know how to make a datagrid with pages (After 10 post it creates another page) .. but I don't know how to access the second page of that datagrid. Can anyone help me in this pls?
2. How to upload pictures using asp.net in Ms Access database not sql.
3. How to make links from a datagrid (each row has a link) to a specific page. How can I make this happen because i dont know how to grab a specific link that the user chose.

1. look here, when the pagination is on, it comes in number format, like 1,2,3,... or in Previous/Next format.
consider the previous next format. when you are in page 5, and click next, the next page index is 6. so e.NewPageIndex = 6.
2. I will prefer to keep the images in a folder in the webserver, and keep the path of the images in database. This is done the way I have told in my previous mail.
3. Lets say your object id is objid in the database and you are binding the datagrid with a datatable which get filled from the database table of objects.
Now the column will be something like this
<br><asp:TemplateColumn HeaderText="Object ID" Visible="False"><br><br> <ItemTemplate><br><br> <a id="lnkID" runat="server" href='Newpage.aspx?id=<%# DataBinder.Eval (Container.DataItem, "ID") %>'>><%# DataBinder.Eval (Container.DataItem, "ID") %></a><br><br> </ItemTemplate><br><br></asp:TemplateColumn><br><br>
For more on datagrids, read my article
How to create the id of <td> and <tr> generated by DataGrid in ASP.NET and use it by client-side JavaScript.
Hope this will do.
