Hi guys,

I am using this project:

http://www.codeproject.com/internet/CustomBrowser.asp

added my own function, which when called returns this error:

object doesn't support this property or method


Here is my function:

void CCustomBrowserDlg::CB_AttachTemplate(int argc, char **argv)
{
      char TargetPath[500];

      CFileOperation fo;

      sprintf(TargetPath, "%s%s\\T\\%s\\%s.%s", ROOT, argv[1], argv[2], argv[3], argv[6]);
      fo.Delete(TargetPath);
      CopyFile(argv[4], TargetPath, true);

      return;
}


any idea why it's not working?

Cheers guys 'n gals!

Have you added the method declaration to 'CustomBrowserDlg.h' also?

jkr,

That's correct, and it seems now that I've sort of found the problem, but can't find the solution...

I've found out that I need to add the function into this file:

Idispimp.h

But I don't understand the structure of the file too well, could you kindly show me what I am supposed to do please? Once I see how one is done, I should be able to do the rest, no problems...

No, you'll have to add that to 'Idispimp.cpp' like

NOTE that the function then is

void CCustomBrowserDlg::CB_AttachTemplate(char *strVal, int nVal)
{
     char TargetPath[500];

     CFileOperation fo;

     sprintf(TargetPath, "%s%s\\T\\%s\\%s.%s", ROOT, argv[1], argv[2], argv[3], argv[6]);
     fo.Delete(TargetPath);
     CopyFile(strVal, TargetPath, true);

     return;
}

modeled after 'CB_CustomFunctionWithParams()'

Sorry, make that

     fo.Delete(TargetPath);
     CopyFile(strVal, TargetPath, true);

Hm, forgot the other parameter - then, we'll have to extend that to


     if(dispIdMember == DISPID_CB_AttachTemplate)
     {
          if(wFlags & DISPATCH_PROPERTYGET)
          {
               if(pVarResult != NULL)
               {
                   
                    VariantInit(pVarResult);
                    V_VT(pVarResult)=VT_BOOL;
                    V_BOOL(pVarResult) = true;
               }
          }
         
          if ( wFlags & DISPATCH_METHOD )
          {
               //arguments come in reverse order
               //for some reason
               CString cszArg1= pDispParams->rgvarg[1].bstrVal; // in case you want a CString copy
               CString cszArg2= pDispParams->rgvarg[0].bstrVal; // in case you want a CString copy
               
               pDlg->CB_AttachTemplate(cszArg1, cszArg2);
          }
         
     }


//...

void CCustomBrowserDlg::CB_AttachTemplate(CString SourcePath, CString TargetPath)
{
     CFileOperation fo;

     fo.Delete(TargetPath);
     CopyFile(SourcePath, TargetPath, true);

OK, it compiled this time, but when it came to calling the function, it waited 5 seconds and then displayed this:


The instruction at "0x10217c5f" referenced memory at "0x00000007". The memory could not be "read".



Any ideas?

I also just noticed, you got rid of my array, why? I need to be able to send an array...

I need to be able to keep the function like this:

void CCustomBrowserDlg::CB_AttachTemplate(int argc, char **argv)
{
     char TargetPath[500];

     CFileOperation fo;

     sprintf(TargetPath, "%s%s\\T\\%s\\%s.%s", ROOT, argv[1], argv[2], argv[3], argv[6]);
     fo.Delete(TargetPath);
     CopyFile(argv[4], TargetPath, true);

     return;
}

So what changes are required in:

if(dispIdMember == DISPID_CB_AttachTemplate)

Is there maybe a way to convert this:

CString cszArg2= pDispParams->rgvarg[0].bstrVal; // in case you want a CString copy

to make use of

CStringArray

and get the results like that? Or is there a lot of work required to make this work? I seriously need to get this working, and am starting to consider offering this question on CodeLance... Will leave it open for a few more hours before I do that though.

The function call needs an equivalent on the calling side.

Regarding the array: That functionality is is a lot more complex than it seems at first glance - let me see...

jkr,

I found a way of reading the values in as an array, but could use some help tidying it up so that it stores it as an actual array, and then parses the end result to my function. Would you mind taking a look at the code, and helping me finish it off?
