Bringing Java / Classic ASP Developer Up To Speed With C# WinForms?
Jan 12, 2010
We're starting a fairly large project that is going to be using all of the company's development resources and I've been asked to help bring up to speed and mentor a co-worker in C#/ASP.NET/WebForms 3.5 who has years of experience with Java and Classic ASP. What are your recommendations and best practices for helping an experienced developer learn the framework and become familiar with ASP.NET best practices? Books or resources? How often should I be conducting code reviews?

I know S#arp architecture is built for ASP.NET MVC. But I'm wondering if it can be used in classic ASP.NET (WebForms) or even desktop applications like WinForms or WPF.

I know how to switch to "Classic Mode" (from "Integrated Mode") in the full IIS via application pool settings. But I can't find how to do it in the current IIS Developer Express beta.
The MS Developer Express FAQ says it can be done, but not how. It's not in the WebMatrix GUI, as far as I can tell. Maybe customization of the Developer Express project file, but I don't see any documentation for that at all.
FYI, there is a Settings area where you can set SSL, CLR version (2.0 in this case), which is where I figure the Pipeline mode (Classic/Integrated) would be, but it's not there.

Normally, I use App_Offline.htm for taking the site offline. But occasionally, when I do that, the site just hangs (like in: browsers wait forever, server gives no response at all). This seems to happen on an updateable site when I change something, like a control and afterward, when it doesn't go quick enough (site hangs), I place App_Offline.htm in the root of the website.
In most cases, this immediately takes down my site. But occasionally it doesn't. In those cases, I cannot just stop the website (when I restart, the behavior continues). Stopping the application pool doesn't let me restart the same app pool. The only two solution so far is restarting the whole IIS web service.
I'd like to prevent this from happening. Is this a bug in IIS not "breaking all actions" when App_Offline.htm is found? I use IIS 7 with Windows 2008 SP2 64 bit.

My application is hosted on IIS6.0 web server. And we observed that the initial page load time is high (30-40 sec) and further page loads take only 5sec.To bring down the page load time, I have deployed the precompiled web solution on IIS.But unfortunately the initial page load time did not came down to larger extent.

I've got an SQL script that fetches results based on the colour passed to it, but unless I set the size of the variable defined as a varchar to (50) no results are returned.
If I use: like ''+@Colour+'%' then it works but I don't really want to use it in case it brings back results I don't need or want.
The column FieldValue has a type of Varchar(Max) (which can't be changed as this field can store different things). It is part of aspdotnetstorefront package so I can't really change the tables or field types.
This doesn't work:
declare @Col VarChar
set @Col = 'blu'
select * from dbo.MetaData as MD where MD.FieldValue = @Colour
But this does work:
declare @Col VarChar (50)
set @Col = 'blu'
select * from dbo.MetaData as MD where MD.FieldValue = @Colour
The code is used in the following context, but should work either way
<query name="Products" rowElementName="Variant">
<sql>
<![CDATA[
select * from dbo.MetaData as MD where MD.Colour = @Colour
]]>
</sql>
<queryparam paramname="@ProductID" paramtype="runtime" requestparamname="pID" sqlDataType="int" defvalue="0" validationpattern="^d{1,10}$" />
<queryparam paramname="@Colour" paramtype="runtime" requestparamname="pCol" sqlDataType="varchar" defvalue="" validationpattern=""/>
</query>
Also I can't set the size in <queryparam paramname="@Colour" paramtype="runtime" requestparamname="pCol" sqlDataType="varchar" defvalue="" validationpattern=""/>

I'm looking for a way to access a Java API from both a Java console application and an ASP.Net application.In short my Java API exposes a series of methods for dealing with invoices. All of these methods are essentially commands e.g.
GenerateAllInvocies
GenerateInvoiceNumber
PrintAllInvoices
PrintInvoiceNumber
All methods will interact with the database. I had believed Web Services was going to be my means for interop. But I have since been made aware of Java Stored Procedures in Oracle.

I got asked to write a java application for my company. I'm a seasoned .Net developer so this is all new ground to me.My task is to produce an invoicing application that has several high level tasks such as:Build single invoiceBuild all invoicesMy company want to be able to call these tasks from a java console application - passing in relevant commands and parameters to invoke the tasks. They also want to be able to invoke the same code from an ASP.NET application.

Why is there a need to explicitly call GridView.DataBind() to render the gridview. Why wouldn't it render by itself automatically like how it happens in Window Forms?

We have an ASP.net application but some screens are deemed too slow to use by our users.As a result, we are trying to provide a WinForms-based alternative to those data-input centric screens so we can use richer controls like Grids with immediate screen updates and feedback for the user.
Ideally, I would like the users to login to the WinForms application using the same credentials they use in the ASP.net application?
Is it possible?I've found this post ( http://stackoverflow.com/questions/1172069/net-authentication-for-both-web-and-winforms ) but it isn't really answering the question from my point of view... We are not using WebServices, or WCF at the moment and do not plan to use it unless it is really the only way to achieve this.

I work with many diverse technologies, and don't possess the time to evaluate every single UI framework, so I'd appreciate hearing other coders' experiences with various frameworks.
The stuff I've worked with so far (and my perceptions):
WinForms: DevExpress (love the looks, hate the API and bloat), Krypton (free!, looks good, but limited), Telerik (don't like the looks)WPF: have only used WPF Themes pack. Asp.Net: Telerik MVC Controls (love it), jQuery UI (looks great)

I need to know whether there will be any problem using win forms control as a custom control in my web app. Problems can be anything related to display, environment where the site is run.
Reason for using is I am not getting the treeview events in web which are there in win app. I need to implement drag drop of treeview nodes to a listbox.

in asp.net we can handle the RowDataBound event of the GridView control. this event fires when every row is added to the gridview.
i want to be able to handle this event in the gridview in a winforms application but i cannot find a similar event. my question is what is the event name that allows me to do the same as RowDataBound in asp.net?

How can i create a window that holds Patient data in it? The 2 records that you see is in List View. I would then using ContextMenuStrip for text "View Details". When View Details is clicked i need to show the context. For web development this could be done via Javascript,div and panels. How that should be WinForms?

Given:
<input id="datepicker" type="text" />
Where the id = datepicker tells the javascript to attach all the datepicker code to the form element, how do I turn this into a server control?
For example:
<input runat="server" id="datepicker" type="text" />
Doesn't work because ASP.net generates it's own ID's.
Edit
<asp:TextBox runat="server" ID="dateTo" class="datepicker"></asp:TextBox>
Renders as
<input name="ctl00$mainContent$dateTo" type="text" id="ctl00_mainContent_dateTo" class="datepicker" />
And doesn't work!

From a class library, I need to determine at run-time whether I'm running in an ASP.NET app or a WinForms/console app. There have been several other questions asked on the subject, but all of those solutions require adding a reference to System.Web. If at all possible, when running my console and WinForms apps, I don't want to load the System.Web assembly into memory just for one line of code out of thousands.

I'd like to create a custom datasource that is shared between a Winforms and Webforms project. This functions as a middle layer for a reporting tool(DevExpress Reporting). The Webforms project is a designer for these reports. So we want for the reports to be capable of going to the server to get data and such. So our datasource would abstract away all the communication overhead. Then, for consistency, the datasource would also run on the server for reporting, except for their would be no communication.
What would be the best course of action? There doesn't seem to be such a thing as a DataSource in Winforms. Is DataSource not the thing I'm looking for?
Edit: After some research, it appears that IDataAdapter may be good for my purpose. Any opinion on that?

After developing ASP.NET apps exclusively for several years I'm about to start developing Winforms apps. What are the gotchas that I should be looking out for with this changes? For instance the way object lifetime is managed in the winforms paradigm. I'm sure there must be plenty of gotchas / differences between the two that I need to be mindful of.
