Hello

VS 2005
I have a web serivce and created the MSI websetup project. Its just a simple web service. However, when i run the setup i get this following message. I can understand that file or reference to a file is missing. but I can't understand what file it is, and how to find out what file it is looking for.

Exception occurred while initializing the installation
System.IO.FileNotFoundException: could not load file or assembly.
file:///C:\Windows\System32\Software\myProject\PC1\ or one of its dependencies. The system cannot find the file specified.

Many thanks for any suggestions,

Steve

What you can do is that you can check the reference node in Solution explorer to know how many assemblies are using in your webserice.

There is one property called "Delete Query" in SqlDataSource. You can set the delete command there.

Or register the Deleting event of the SqlDataSource and set the query there.

Hi, i'm kinda new to the whole asp.net side of developing. I've created a web page with a combobox and textbox. I have a Database with a table (Postcodes).

First of all, how do i populate the combobox with data from this table (column: towns) and, second of all, when i change item, how do i make the textbox display the postcode (a.k.a. zip code) (column: postcode).

I am using visual basic as my language in visual studio 2005 with a seperate codepage for my aspx page.

Please check out my articles:

Menu is messed up when the datagrid is too long??

Hi,
I have a problem when I display a datagrid that contains too many rows the asp.net menu control is messed up in Internet Explorer. The only solution to this problem is to page the datagrid but I can't do that coz the user can edit and add data in it...so I don't know how to handle this problem??

Messed up meaning the menu is supposed to be horizontal with a certain style but when displayed it becomes vertical and the styles and colors are gone!!! The menu items become links?? And I noticed that this happens only when the datagrid displayed in the same page contains too many rows.
Can someone tell me why does that happen and if there is a solution to this problem??

Creating and using a dll as a code-behind file

chris_wanaka11-Aug-07 17:35

11-Aug-07 17:35

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

My requirement is that when i log out, then again when i open the url , and puts the same emailid then its password should automalically come in password textbox.

Is there anyother way to achieve this.

Thanx

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!
