C# - Web Service - Currency Input

Feb 11, 2011

Web service API: I noticed that some companies like to pass integer as the "currency" amount, rather than pass a decimal data type with a decimal place ($ 100.29) is there a good reason why they choose integer for currency over decimal data type? Example, they do this

100 = $1.00
10043 = $100.43

Why not do this

1.00 or 1 = $1
100.43 = $100.43

C# - Using Forms Input To Upload File To Web Service

Feb 12, 2011

I am using ASP.NET 2.0 and trying to use a simple Form to upload a file to a web service. I have the action attrib set to the url of my web service. However, in firefox, I can't see that it is making any call to that service at all. NOTE: I can throw int the below "Action" value to a browser minus the name of the web method and get a page showing the available web method so I believe the URL for the "Action" attribute is correct.

<form id="fileUpload" action="http://localhost/AcmeABC/services/FileUploadService.asmx/ImportRates" method="post" enctype="multipart/form-data">
<input type="text" id="fileName" name="fileName" />
<asp:FileUpload runat="server" id="fileArray"/>
<input type="submit" value="Submit" />
[WebService(Namespace = [URL]/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ToolboxItem(false)]
[ScriptService]
public class FileUploadService : System.Web.Services.WebService {
[WebMethod]
public void ImportRates(string fileName, byte[] fileArray) {
try {
MemoryStream memoryStream = new MemoryStream(fileArray);
}
catch (Exception ex) {
string error = string.Format("Error thrown for file {0} with {1} error.", fileName, ex);
}
}

How can I see what is going on since I don't see any call be made. I am also of the opinion that this might not be the best approach. I am new to the entire web development space so I am trying to find better ways of handling problems.

VB.NET Web Application Input Box / Input Box That Comes Up When A User Clicks 'Find' Button?

Aug 4, 2010

I would like to program an Input Box that comes up when a user clicks 'Find' button. It asks 'Please enter an employee number'. Then it takes the employee number typed into a text box and searches a dataset for that specific employee record.

I know that it should be server side because the client may not have the proper javascript installed or diabled. Therefore, can someone give me some code to put in code behind that can pop up an input box and use the input after, if this can be done?

Use Same Currency Symbol And Formats?

Apr 4, 2011

I have a field that I display via:

String.Format({0:c},amount)

This produces the string "$28.28" However, when I try to convert back to a decimal amount, I get an incorrect format exception:

amount = Decimal.Parse(amount.Text, NumberStyles.Currency)

I also tried it with NumberStyles.AllowCurrencySymbol with the same results. I verified that the value in amount.Text is "$28.28". Am I missing something? Shouldn't these two operations use the same currency symbol and formats?
