Creating and using a dll as a code-behind file

Hi,

I would like to use a .aspx.vb code-behind file to create a dll which I can then use as my .aspx page's code-behind file in place of the .aspx.vb one.

The reason I would like to do this is that I would like to distribute existing code from my 'sandbox' in an application I'm developing for a client, but do not want to provide the client with the .aspx.vb source code.

I am using Visual Basic / Visual Web Developer 2005 Express Edition (ASP.NET 2.0).

So far I have tried:
1. Importing the .aspx.vb file into a new VBEE project and trying to build the project. This doesn't work because the references to controls on the .aspx page aren't recognised in the VBEE project.
2. Investigating the possibility of using the code compiled when the site is built be the .NET framework. I have looked all over the place for an answer/dll file, but haven't come up with anything.

Well I've run out of ideas on this so if anyone is willing to help that would be great. If you've not got a complete answer, just some ideas of where to go to investigate further would be great.

Many thanks,
Chris

This is a function in the browser, and the user decides if the function should be used or not.

You can't control this functionality programmatically, and there is no way that you can set the value of a password textbox using code.

Need help with opening new ie window from a databound DropDownList

I am lost. Please someone help! Smile | :)

What I am working with:

VB with code-behind, databound dropdownlist with columns of linkname and linkaddress

I have been unable to successfully figure out how to write a javascript function that opens a new window in IE when the selecteditem is changed.

Can anyone help me?
Smile | :)

To do exactly what you are asking for is (AFAIK) impossible using only Javascript. To open a new window in a specific program (in this case IE) requires you to run an executable on the client computer.

To open a new browser window, however, is easy:

onchange="window.open('PageToOpen.aspx','_blank');"

You can add the value of the selected item as a querystring:

onchange="window.open('PageToOpen.aspx?someNiftyName='+this.options[this.selectedIndex].value,'_blank');"

You also can set the onchange attribute from code behind:

TheDropDownListControl.Attributes("onchange") = "window.open('PageToOpen.aspx','_blank');"

I'm sorry I am still not understanding it...

Here is what I have:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

End Sub

Protected Sub DropDownList1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles DropDownList1.SelectedIndexChanged

End Sub

I guess I am not as savvy as I thought. Where do these codes go? Is there javascript involved? I also forgot to mention I am coding this in asp.net in a web form not a windows app.

Thanks for your help!

In the markup code. In the aspx page.

Yes. You have to use Javascript to open a new browser window. That can not be done using ASP.NET code.

The event happens in the browser, and the new window has to be opened in the browser, so there is no reason to use a server event to do it.

I also forgot to mention I am coding this in asp.net in a web form not a windows app.

As you are posting in the ASP.NET forum, I took that for granted.

ok Here is how far I have gotten. Please let me know I am so close!

Javascript:

function openOrange(selObj,restore){
var theFullString = selObj.options[selObj.selectedIndex].value;
if (restore) selObj.selectedIndex=0;
var theLength = theFullString.length;
var endPos = theFullString.lastIndexOf("~");
var theUrl, theTarget, theParent;
if (endPos > 0) {theUrl = theFullString.substring(0,endPos);}
else {theUrl = theFullString;}
endPos++
window.open(theUrl);
}

PageLoad event:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
DropDownList1.Attributes.Add("onchange", "javascript:openOrange(this,1)")
End Sub

Got it to work finding some javacode for a jumpmenu. Anyone know how to clean it up?

Hi,

Is there a way of creating help documents something similar to the MSDN Help 2008? I have a web app and I need to create help files for my classes and methods, constructors, etc.

It must preferably be free, but price shouldn't be an issue.

Silly little thing with GridView and DetailsView

Hi all.
Ive got a silly little problem irritating the hell out of me. I binded a GridView to a collection in the code, as we had to loop through several tables to retrieve the correct specific record. So I did the same for the DetailsView and everything seems to be working, in terms of they both show the correct details. But the irritating problem is that when i select a record in the gridview to display it in the detailsview, I have to click the "Select" link once, which seems to highlight the row, and then click "select" a second time to display its details.
This irritates me as I know from when I used smart tags before, I only had to click once.
Does anyone have an idea whats wrong? or what i need to do?
Much Appreciated

Hi,

I am created a web application such as, if user want to upload photo. He can drag photo from window explorer and drop it on animation control over the web page and upload it by simply clicking the upload button. The paths of these photos are inserted into html select control.

So, my qery is,
is any ActiveX control which I can use for uploading the files ?

Here I am not using the InputFile control so I am not able to upload the files on server.

By "File.copy(source, destination)" I can upload the file locally.

Any one can give me answer for this? Rose | [Rose]

I have this code:
lable.text = hr.GetDataByReturnRequestNumber(((TextBox)FormView2.FindControl("DropDownList3")).Text, ((TextBox)FormView2.FindControl("AreaTextBox")).Text, Convert.ToInt32(((TextBox)FormView2.FindControl("OrgCodeTextBox")).Text), Convert.ToDateTime(((TextBox)FormView2.FindControl("InsertDateTimeTextBox")).Text));

and I got these 2 errors:
1- cannot implicity convert type 'DH.RequestFormDataTable' to ''string'
2- Unable to cast object of type 'System.Web.UI.WebControls.DropDownList' to type 'System.Web.UI.WebControls.TextBox'.

can any body help me with it please.....

Re: casting problem

Guffa11-Aug-07 2:34

Is the method returning a DH.RequestFormDataTable? Then you can't put that in the Text property of the label. What is it that you want to put in the label?

I suppose that DropDownList3 is a DropDownList and not a TextBox? So why are you trying to cast it to a TextBox?
