View 1 RepliesI have this method which does not build, it errors with the message:
Cannot implicitly convert type 'System.Web.HttpPostedFile' to 'System.Web.HttpPostedFileBase'
I really need this to be of type HttpPostedFileBase instead of HttpPostedFile, I have tried boxing and it does not work:
foreach (string inputTagName in HttpContext.Current.Request.Files)
{
HttpPostedFileBase filebase =HttpContext.Current.Request.Files[inputTagName];
if (filebase.ContentLength > 0)
{
if (filebase.ContentType.Contains("image/"))
{
SaveNonAutoExtractedThumbnails(doc, filebase);
}
}

View 2 RepliesUsing C# I was trying to develop the following two. The way I am doing it may have some problem and need your kind advice. In addition, I dont know whether there is any existing method to do the same.
private static String HexConverter(System.Drawing.Color c)
{
String rtn = String.Empty;
try
{
rtn = "#" + c.R.ToString("X2") + c.G.ToString("X2") + c.B.ToString("X2");
}
catch (Exception ex)
{
//doing nothing
}
return rtn;
}
private static String RGBConverter(System.Drawing.Color c)
{
String rtn = String.Empty;
try
{
rtn = "RGB(" + c.R.ToString() + "," + c.G.ToString() + "," + c.B.ToString() + ")";
}
catch (Exception ex)
{
//doing nothing

return rtn;

So, I've been programming for a number of years. Finding some intricately asinine issues w/ ASP.NET and VB.NET as I learn them. How about this one:
[Code]....
The issue is not Date1
The issue is Date2.
No kidding. I had to String.Format Date1 for some odd reason, even though I'd already validated it. And, yes, I tried to parse and convert Date1 but I kept gettting the typical "Argument 'Date2' cannot be converted to type 'Date'." error. (Did you catch the copy & paste? I didn't edit it from my existing error, but Date2 should be Date1.) Yeah, that's the error I'm getting now with the above ...
"Argument 'Date2' cannot be converted to type 'Date'."
Date2 is a system defined type. Why can't the system convert and/or simply use it's own pre-defined type?

View 1 RepliesI am looking into making a voting system for an event.
I would like to base the voting system off of MAC addresses. I would like to get the voters mac address, check to see if they have voted within the last 5 minutes, if they have not, let them vote and add their mac address and current date-time to a table as a record. If they have voted within the last 5 minutes, i would then inform them and tell them to try again later. If it has been longer then 5 minutes, i would clear their record from the database, let them vote and add a new record with their mac address and date-time.
The problem with using IP, is that most of the people voting will be on the same network (large organization) and i believe the ip the website would pickup would be the same.
I want to log all errors happened in my App to sql db. I'm passing all exception properties like (ex.Message, ex.Source, ex.StackTrace, ex.TargetSite and ex.InnerException) to stored procedure.
The problem is that when I try to pass the ex.InnerException as string to stored procedure I got this error:
Cannot implicitly convert type 'System.Exception' to 'string'
I tried ex.InnerException.ToString() and Convert.ToString (ex.InnerException) but no success.

I am getting the "Unable to convert MySQL date/time value to System.DateTime" error because from what I can tell I have a record with 0000-00-00 00:00:00. Now while the data should never be that (it should be null) there are cases when this might happen and I don't want my entire application to crash because of it. I am using NHibernate and I tried adding change my connection string to allow zero datetime so the connection string configuration looks like:
<property name="connection.connection_string">
Server=localhost;Database=user_system;User ID=root;Password=root;
Allow Zero Datetime=true;
</property>
However I still receive that error. How can I allow NHibernate to allow zero values for timestamp/datetime/data/time?
I am importing data from Excel sheet to a database. The table in the database has a special column where I store Interior.ColorIndex of each row in Excel. Then I display the data in a GridView. I need its rows to have the same or close colors as corresponding rows in Excel. I cannot find how to convert the color information I store in my database into System.Drawing.Color (in other words, to RGB) to apply to my GridView.

We are designing a system that has functionality that is essentially the same at the presentation layer and the exposed API layer. My question is what technique / strategy to use so we can get the most reuse out of our code with performance in mind? Here's a simplified example: A user can add a Customer via a web form. This will fire the Customer.Create() method. An API consumer / user can add a Customer via a SOAP / HTTP-POST to a web service which will call the Customer.Create() method.
Imagine these layers:
PRESENTATION
|
|
WEB SERVICE API (Customer.Create() is available here
|
|
FACADE Business Object Interface - Customer.Create() signature is here
|
|
BUSINESS Business object - Customer.Create method() is fleshed out here
|
|
DATA ACCESS - Writes data
The presentation layer SOAP calls the Create() web method, which calls the facade's Create() method which calls the business object's Create() method which wires via the data access layer.
Questions:
Is there a concern about performance in using the API's web services in our presentation layer, or are there alternatives to connect the presentation layer directly to the facade? If so, what technology to use (WCF, Remoting, Web Services, etc)?

View 2 RepliesI have created a method i.e. getAddress as mentioned below. protected void getAddress(string Address)
{
myAddress = "New";

When I run directly as

It works perfectly, but when I run as
string txtProperty.Text = getAddress("some address);
It giving me following error

It seems this not the correct way to call this?
