Web Reference Null

[clafean]

I am building a app using a web reference. This particular app is currently configured for the desktop. I have modified working existing c# code. All of the methods work correctly except the ones that need to pass a null value into.

An example c# call: jt.SetOutputInfo(xmp_user, xmp_pass, jtid, "PDFO", 1, null, null, null);
is replaced by jt.SetOutputInfo(xmp_user, xmp_pass, jtid, "PDFO", 1, null, null, null)
(I have a variable null dimmed as c set to null_value().)

This is not working. I have also attempted "", to no avail. This symptom is consistent with all methods that require null values to be passed.

I have been working on this all day and am at the end of my wits... anyone have any help?

Re: Web Reference Null

Perhaps a bit more info, the variable I am trying to pass a null into is a value pairs type variable. The null works in c#- can anyone provide an insight as to how to set this variable in AA?

This is the info on the method:

public bool SetOutputInfo(
string inTicketID,
string inType,
int inMedia,
string inFolder,
string inFileName,
Parameter[] inParams
)

Here is a c# example:

jobTicketWS.SetOutputInfo(uName,
password,
jobTicketID,
"PDFO",
1, "", "",
null);

Here is a VB example:
jobTicketWS.SetOutputInfo(uName, password, jobTicketID, "PDFO", 1, "", "", Nothing)

BTW, the only reason this is in the Mobile and Browser app section is because it uses a web reference and it will ultimately be deployed as a browser based app.

Re: Web Reference Null

A character variable set to a null value is not the same as a null. Pass null_value() directly, such as:

jt.SetOutputInfo(xmp_user, xmp_pass, jtid, "PDFO", 1, null_value(), null_value(), null_value())

Re: Web Reference Null

Thanks Lenny. I had already tried that and just tried it again with the same result; still not working. Here is the error I get: (for this one I have the two character fields set to "", which is working in other methods, but I get the same error regardless)

When I try to create what I think matches a value pair variable:

dim inParams as p
dim inParams.m_Name as c = "ASSET_POLICY"
dim inParams.m_Value as n = 2

and then pass inParams I get this error:

Re: Web Reference Null

The first error is saying there is because there is no method prototype that takes the number and type of arguments you have supplied.

The second error is indicating that an Xbasic P cannot be implicitly converted to a .Net class of the expected type. You will need to dim a Parameter[], then pass that. This should work with it null, or with it containing actual values.

Re: Web Reference Null

Are you suggesting that I dim the Parameter[] in AA? If so, how? Otherwise, can you please be a bit more specific?

Re: Web Reference Null

That is exactly what I am suggesting. But I can't be more specific because You have not provided the details of the exact class you are trying to use. But to point you in the general direction, here is how you would do it with a .Net NameValueCollection

dim Collection as System::Collections::Specialized::NameValueCollection
Collection.Add("Name", "Value")

Re: Web Reference Null

I think we are getting close... this is the code for the method:

[System.Web.Services.Protocols.SoapDocumentMethodAttribute("XMPieWSAPI/SetOutputInfo", RequestNamespace="XMPieWSAPI", ResponseNamespace="XMPieWSAPI", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
public bool SetOutputInfo(string inUsername, string inPassword, string inTicketID, string inType, int inMedia, string inFolder, string inFileName, [System.Xml.Serialization.XmlArrayItemAttribute(IsNullable=false)] Parameter[] inParams) {
object[] results = this.Invoke("SetOutputInfo", new object[] {
inUsername,
inPassword,
inTicketID,
inType,
inMedia,
inFolder,
inFileName,
inParams});
return ((bool)(results[0]));
}

Re: Web Reference Null

This is what I get with the Collections namespace:

Re: Web Reference Null

I used System::Collections::Specialized::NameValueCollection as a general example and was not suggesting it would work for you. You need to instantiate the correct class for the object you are working with. Your post #8 indicates that what you need is a System.Xml.Serialization.XmlArrayItemAttribute. You can create one with

dim inParams as System::Xml::Serialization::XmlArrayItemAttribute(.f.)

Re: Web Reference Null

That results in an a5 error:
