Does the class that was generated have the namespace you're trying to use ?

You mean the reference.cs that's created when I add the web servce reference or the name of the entire class I'm trying to create?
If it's the former then I think so... my solution and project are both called PayPalAPI and in it I have created a new class called APIWrapper.cs which, when compiled, is to be used to call PayPal services from other .Net apps. The namespace of this class is PayPalAPI. The namespace of the reference.cs that was generated after adding the WS is PayPalAPI.PayPalSvc. (I had to rename the WS from com.paypal.www to 'PayPalSvc' when I added it.)
Does that help or have I confused you?
Thanks for bearing with me - I've used web services before so can't understand what's happening here!

'PayPalAPIInterfaceService' is what you can't find - where did it come from, and does it appear in your code ? Could it be a reference to something that was renamed when you renamed the WS ?

'"PayPalAPIInterfaceService" description' is what the WSDL screen shows when you type the reference to the PayPal web services (http://www.paypal.com/wsdl/PayPalSvc.wsdl) and hit "go". It says "1 service found - PayPalSvc" and the name is com.paypal.www. I rename that to PayPalSvc and click "Add Reference". The code below in my wrapper class then tries to access PayPalAPIInterfaceService. (I've marked the error lines with "//GETS ERROR HERE".... that's where the compiler says it can't find PayPalAPIInterfaceService.)
If you want I could zip up the project and email it to you or make it downlaodable from my server... it might be easier to see waht's going on - let me know if that would help.
Thanks again,
Mike

Actually, if you could give me the URL to generate the web reference, that may be just as good.

I'm not sure what happens if you try and add it without a local certificate from PayPal (to use it's API)... I have the cert for our merchant account installed in the PErsonal and Other People certificate stores.

I was able to add the web service, but it did not wrap "paypalsvc" in another namespace, I was able to create and manipulate objects using PayPalSvc.Classname varName = new PayPalSvc.Classname(). I'd search across the project for 'PayPalAPIInterfaceService', and see where it's expecting to find it. It does not appear within the webservice, the problem is elsewhere.

Ok, well thanks for trying.
I'm now starting from scratch with a very simple forms app that uses the service (the code I had for the APIWrapper class was from the "PayPal Hacks" book) so will see what luck I have with that.
I also now have a direct technical support contact at PayPal so hopefully if the problem persists he will look at it.
Many thanks for your help.... it was much appreciated.

I want to get a date with the "dd/MM/yyyy" format in C#.net, but when I write the code like
date_txt.Text = System.DateTime.Today.Date.ToShortDateString;
In the textbox it shows 2005-08-03, this format. And it can't be written into the access source database.
Does anybody know how to get "dd/MM/yyyy" this kind of date format and write it into access source database???
By the way, if I want to display some record between two dates, any ideas???
Many Thanks
Asura

The display format is independant of the way the date gets stored in Access. The default display format depends on your locale settings. To write dates to access (or any database, for that matter) the best approach is to use parameterised queries, and pass the date as a parameter of oledbtype.Date, which maps directly to System.DateTime (access uses the double seconds since 1899 as its storage type).
To display the date, you could specify the format:
<code>
date_txt.Text = System.DateTime.Today.ToString("dd/MM/yyyy")</code>
To display a date between two dates, use a parameterized query:
<code>string myQuery = "Select * from MyTable where MyDateField Between ? and ?"
OledbCommand myCommand = new OleDbCommand(myQuery, mYDbConnection);
myCommand.Parameters.Add("@StartDate",startingDateTime);
myCommand.Parameters.Add("@EndDate",endingDateTime);
OleDbDataReader dr = myCommand.ExecuteReader;
while(dr.Read())
{
...
}</code>

Thanks for your code. Could you tell me how to declare the variable as OleDbType.Date please, because I tried that, and it says that OleDbType.Date is a field but not a class. Therefore I still don't know how to pass the date as a parameter. Also, if I want to change the local settings, where can I find it please?
Thanks in advance

Are you sure that you can't use a date with that format with Access? That date format follows the ISO 8601 standard, and it is unambigous. I have never had any problems with that date format.
The dd/MM/yyyy format on the other hand is ambigous. The date 03/08/2005 can be interpreted either as 2005-08-03 or 2005-03-08.
I am not convinced that it's the date format that is the problem. How do you enter the date into the database?

I used a number of ways of writing the date information back into the database. For example,
DataTable table = ds.Table["Customer"];
table["date"] = System.DateTime.Today.Date.ToString("dd/MM/yyyy");
||
table["date"] = Convert.ToDateTime(System.DateTime.Today.Date.ToString("dd/MM/yyyy"));
||
table["date"] = System.DateTime.Parse(date_str);
I try the above ways, but none of them works.
Could you tell me how you enter the date into the database please??

Each of the methods you tried involved converting a string to a date. That means that you rely on the culture specified by default to correctly interpret the date. Obviously the default culture is not the one you wish to use, so it doesn't.
Provide a DateTimeFormat for the culture you wish to use. I would use a swedish CultureInfo (LCID 1053) to parse a date in swedish format:
string dateString = "2005-08-05";<br />
table["date"] = System.DateTime.Parse(dateString, new CultureInfo(1053).DateTimeFormat);

I was just wondering what you guys are using to protect the applications written in any language under the .Net Framework. Do you prefer the exe packers and crypters, or some other schemes?
Which scheme is the best to implement, and presents a good ratio between a price/time to implement/protection it offers?
Thanks.

Hi Damir,
Its realy difficult to protect a .NET Application, because the application is only IL-Code (with a win32 loader) and you can recreate the code of it really good.
Try Lutz Roeder's Reflector[^], for instance with the System.dll (Framework Namespace System).
One solution is to use a obfuscator. The obfuscator renames all variables and methodes in useless terms, like a12423.
But a have no tip for a special product.
A communication version (free for students and freeware authors) of the dotfuscator is part of visual studio 2003. See: http://preemptive.com/products/dotfuscator/Editions.html[^]
A free alternative is the Aspose Obfuscator/[^].
An other idee is to pack all used dll's in one stream and embedded this stream as embedded resource in the application. Unpack this stream at runtime and load the dlls from this unpacked memory. Its simple possible to crypt the embedded stream.
A example implementation is descript in the magazin Dr. Dobb's Journal March 2005.
Reducing the Size of .NET Applications[^]
Hope, it's help a bit

I have a form with FormBorderStyle set to Sizable, and no minimize or maximize buttons, and no ShowInTaskbar. It displays the default Windows Forms icon in the title bar, even if I set the Icon property to null in the constructor.
Is there a way to have a sizable dialog without that little icon in the caption? How?
Thanks!

The only way to do it is to set the icon to an image that matches the color o the title bar. You can't not have an icon there.

There are two other ways:
1st way:
It's most like the idea of Dave.
Use a icon where all pixel are transparent.
2nd way:
Set the borderstyle to sizeable Toolwindow. The caption bar is a bit smaller.
