I have a requirement to add one line of text automatically to the end of the all web pages in a web site in IIS (all virtual directories under the web site). I am trying to write an HttpModule using ASP.NET/VB.NET which can do this. Do anybody have some sample code to share?

Thanks in advance.

You can see the sample code in the howto below, also you should understand the application events so that you can apply the custom http module in the right way:

ASP.NET for Pocket PC

Hi guys,

I'm actually quite new to ASP.NET programming. The program that I'm building now is related to coding an ASP.NET web service for my Pocket PC.

My question is, can ASP.NET run on Pocket PC? If yes, do I need any special applications or just Visual Studio 2005 could do the job?

Another problem thats bugging me is the fact that the screen for Pocket PCs are smaller, so do I need to set a specific height and width for my website, or do all Pocket PCs auto shrink the website to fit their screens?

Thanks

No. ASP.NET is a server side technology and is designed to run on a server system.

Try some websites on your PocketPC and see. I tend to use the low graphics version of websites if available. Some services, such as gmail, detect if it is being used via the browser on a PocketPC and adapt themselves to the smaller screen and lower bandwidth availability. Some ASP.NET controls will adapt the HTML they render to the smaller formfactor, but it still requires some work from you to get it working well on all systems.

The Async nature of the database connection probably won't be felt by the end user because the whole web page has to be defined before it can be rendered to the client and it can't render itself until the query returns.

The alternative is to create a control that can be displayed to tell the user to wait. That is, when the user presses the button that initiates the lengthy query they are presented with a "please wait" message until the new page is available.

Newbie needs table help

12-Jun-06 4:54

I have these three tables in my database - outcome (primary key:outcome_id), assessment(primary key:assessment_id) & outcome_plan(foreignkeys: outcome_id & assessment_id)

I have created a dynamic table at runtime taking the headers from the Outcome Table with dtOutcome = Outcome.GetAll(m_ConnString) and the Row headers from the Assessment Table with Assessment.GetAll(m_connString). I need to fill in the individual cells with the info from the third table with Outcome_Plan.GetAll(m_connString) - naturally I need to drop the info into the corresponding rows and columns. Can someone please start me off on this?

I understand that I need to loop through the column records first find a match for column and then loop through corresponding rows until I find the correct one and then insert the data into the right cell. Not sure of where to start with syntax in vb.net

Thx, Tammy

Read rule number 4 in this[^].

You can't use a server control to call the javascript to validate the form. When the event runs to handle the server event, the form has already been posted. You have to call the function from client script.

Here is an example on how you verify a form using client script:
Javascript: Validate form[^]

You can put a validator in edititem template. In EdititemTemplate give your textbox a ID.
YOu can do soemthign liek this:

<EditItemTemplate>
<asp:TextBox runat="server" ID="tbProjects" Width="255">
</asp:TextBox>
<asp:RequiredFieldValidator ControlToValidate="tbProjects" </asp:RequiredFieldValidator>
</EditItemTemplate>

You can replace requiredfield validator with anyother kind of validator.

Hope thisone works for you!!

There is no 'Click' event, that's true, but there are several events serving mouse click, depends on where in datagrid you click. What event exactly are you looking for? Probably SelectedIndexChanged (when you select a row), I suppose...
Anyway, select your grid in Page Designer, then right click your grid in Page Designer and select Properties. In properties window click on events icon ('lightning' icon) and u will see all supported events of datagrid.

I'm not sure if this is your problem, but deploying your Crystal Reports Viewer in a Web environment requires you to have licenses...

I never understood how exactly the license thing worked (in web environment or windows forms environment, ...), but you can read about it on the internet.

hope this helps...

Coulda, woulda, shoulda doesn't matter if you don't.
