JVariant out

[PDV PDVMIPV]

Hi

I needo to call this function:

HRESULT CreateIadsTimeArray( int RequestedPoints,  VARIANT* TimeArray ) ;

I tried with this code:

JIVariant varTimeArray = JIVariant.EMPTY_BYREF();

dispatch.callMethodA("CreateIadsTimeArray", new Object{NDATA, varTimeArray});

but a the end the variable varTimeArray don't contain the Array of Dispatch that it should be contains.

Can you help me?

Okay,  then please try OUTPARAMforType(IJIDispatch.class,true);

[PDV PDVMIPV]

Below the error with the code  JIVariant varTimeArray = JIVariant.OUTPARAMforType(IJIDispatch.class, true);

Exception in thread "main" org.jinterop.dcom.common.JIException: The stub received bad data. Please check whether the API has been called in the right way, with correct parameter formation.

Okay, do you have a native sample ? We can have a look at the Wireshark capture.

[PDV PDVMIPV]

Unfortunally I don't have the source code of the DLL.

The test was made with a special simplification of the dll.

I have the DLL that i really need to use.
This DLL works perfectly with J-Integra,
if you want, I can send to you the dll and java code that use in java with j-integra?

About the Wireshark I don't know how I can use it, the dll that I call is localized locally in my machine.

Thanks

[Vikram Roopchand]

Okay , please send the code to the support address.

thanks,
best regards,
Vikram

I sent to you the DLL and my code at address: vikramrc@users.sourceforge.net

Do you recive it?

How to pass in and out method parameters to a method call?

Example:

void CheckPasswordExist( string Command, uint32 ReturnCode , uint32 PasswordExists);

Here I have to set a value for in parameter Command.
Output will be passed to password exists.

I tried with this code:
JIString cmd = new JIString("Admin");

JIVariant result = dispatch.callMethodA("CheckPasswordExist", new Object {
                                                                                                                     new JIVariant(cmd),
                                                                                                                     new JIVariant("ReturnCode", true),
                                                                                                                     new JIVariant(""PasswordExists", true)
                                                                                                               }
                                                                                                         );

Is this correct way of passing in and out parameters?

[Vikram Roopchand]

Hi,
     Please have a look at JIVariant Javadocs for Out params.

thanks,
best regards,
Vikram

[wmiquest]
