I want to make an proposal to migrate an ERP like software from Delphi to .Net.The existing software is in Delphi 6 and it is a desktop application.I want to highlight the benefits of moving to .Net (May be Web application) rather than upgrading to latest version of Delphi.

I have data for the payment system:
- Credit card number (Visa, Mastercard, etc ...)
- Paypal
- Moneybookers
- NETeller
- Etc ...
how to set the table and columns.
Current proposal:
Column AttributeName, in which I have text (credit card number, name on credit, email, etc ...)
Column Value, in which I have data about a particular attribute.
I wish that all data is stored in one table.I do not wish for any payment system, use the new table, as for example:
tbl_creditcardnumber, tbl_paypal, tbl_moneybookers, tbl_neteller ....
I have created a dynamic web page . It gets loaded using a file keys.txt. This file holds the keys which are used to display a web page like panels order, text of labels , number of buttons and so on..It is consuming a web service written in delphi. All works fine but when 2 users try to access this service simultaneously then a error is displayed (Internal Server Error 500) "Access violation at address 0040404C in module "accelerate_gateway.dll". Read of address 00000000"Accelerate gateway is the name of delphi web service.It seems to me the problem of multi threading in delphi service ??But I have not done any multi threading in client asp.net page as well. ??It simply creates web service object and access its methods.As I am using a file contents to load a page, so I am concerned if it can create trouble as well ?? . Although I have used FileShare.ReadWrite in it.

in asp.net can i make public objects on my page, for example

a single object will be created for all users??? or each user will have a different object?
I'm working on a webforms aspx app (not MVC) and I'm not sure if I should just create separate pages or somehow make multiple views on the same aspx page for the following scenario: Basically, I need to give the user the option to view a set of data a few different ways (essentially different group by's from a data perspective)... the data is always the same, its just a matter of how to arrange on the page...
each way I need to present the data will essentially consist of 2 repeaters, one nested inside the other. The outer repeater will display a nice header section with the nested repeater showing the list of items under that heading. view by book title (title is outer repeater, with the book list being the nested repeater, yes, multiple books with same title for this example - the app has nothing to do with books, this is just to illustrate)

Or, view books by publisher (here the publisher would be the outer repeater and the list, with different fields compared to first view, is the nested repeater.

so what do I do here? Just making separate pages is simple and would work, but is there something else I should be considering? There will be 3 different views, so 3 pages total if I went that route. Something is making me think I should be doing this all within one aspx page? maybe just toggling the visible property of the repeater controls? but then I was thinking each of these repeater controls is databound, and I assume even if they are not visible they still incurred database hits to get the data, right? and that could be bad?
I am planning to create HR Management System using asp.net & sql server 2005. In this application we need to manage different kinds of Employee Documents like Offer letter,Salary certificate etc.. Now,What we need is we will store templates for these documents(ms word,excel) in the application and needs to genereate these documets corresponding to the selected employee like mail merge.
View 3 RepliesI have seen this for a long time, and finally decided to put the question up here. I have some applications that I need to maintain that were written in Delphi 2007 for .NET (ASP.NET 2.0). Normally, the first time I run the application (using IIS) I get the classic "Unable to start debugging on the web server. Unable to attach to ASP.NET worker process" message. I simply press F9 (run) again, and it runs. Sometimes I have to try running several times before it will actually run. I am running Windows 7 64-bit (and have seen the same effect on Vista 64-bit). I do have IIS configured for ASP.NET, and I do have the following code in my Web.config file.
<system.webServer>
<modules>
<add name="DbgConnect" type="Borland.DbkAsp.DbkConnModule,Borland.dbkasp,Version=10.5.0.0,
Culture=neutral, PublicKeyToken=b0524c541232aae7" preCondition="managedHandler" />
</modules>
<validation validateIntegratedModeConfiguration="false" />
</system.webServer>
The point is that I eventually can run the application in the debugger, sometimes even on the first try. Many times when I get the failure it happens about 15 seconds or so after I press Run, sometimes even after I've hit a page or two (or three) of the Web app. And, yes, when Delphi gets into this mode, I can simply run without debugging, and all is fine (unless I really want to debug). And, I can just keep on trying to run in the debugger and eventually it will just work.
It appears that Delphi's .NET debugger is somehow getting the idea that the application cannot run, and then gives up and stops the process (which as I've mentioned is sometimes clearly running). I know of other developers who have also seen this behavior. My question is, does anyone know how to stop this annoying behavior?
I am facing a decision now on how to make a "watch this item" function, like the one on ebay!I was thinking to make a SQL datatable with two fileds, for example: UserID and ItemID, anto store data there,
but I am afraid if I do it like this, my server performance will slow down. For example if I have about 10.000 users and everyone is watching just about 5 items, then my datatable will have about 50.000 entries. I am not really familiar with server performans when dealing with such big datatables. What do you think? Am I going to face problems with server performance
if I do it this way?Second method that I was thinking is to automatically create a datatable for every user in which ItemID will be stored later. With this method I will not have a huge datatable, but then I will have about 10.000 small datatables. Is this a better method?

View 4 RepliesI have inherited an ASP.net website that was originally started back in 2007. I believe that a lot of the codebase was written in version 1.1, patched to 2.0 where necessary. The client is still not happy with some features and has requested changes to be made. In "peeling back the onion skin" I found that the codebase is rather outdated. I have asked and received approval to upgrade the entire application (website plus VB library) to ASP.net 3.5. Besides following the standard help instructions in VS 2008 and the advise of other posters on this site, can anyone direct me to specific resources to utilize in reviewing the 1.1/2.0 codebase and selecting the best 3.5 constructs that are most compatible? Do you favor the approach of converting the codebase in VS 2008, or do you start with a clean slate and copy/paste code where necessary? The original codebase uses Anthem and Free Textbox libraries. Do you favor upgrading these libraries to 3.5 where available, or are there other (free) libraries that will do a better job?

Before you start using VS2010 RC, knowing that the RC version was launched with a serious bug as reported on the link below.The bug is related to the use of controls within containers in an ASP.Net application, and like almost every ASP.Net application has any container, it is impossible to migrate an application VS 2008 to VS 2010.Before you start any work or migrate to the IDE of VS2010 RC, you know this bug.
View 20 RepliesI have an existing application that displays Google Analytics data. Currently, it stores the username and password which I do not like, so I wanted to convert it to use OAuth. I have isolated the authentication method to get the token in hopes that all I would have to do is change this method:
public static string getSessionTokenClientLogin(string email, string password)
{
//Google analytics requires certain variables to be POSTed
string postData = "Email=" + email + "&Passwd=" + password;
//defined - should not channge much
[Code]....
Is there an easy way to convert this to OAuth? I can change the parameters, but I am hoping I do not have to make architectural changes to the rest of my app.
