hello, have some troubles getting some code working.
if you can have a look.

I have the code below, and it does insert only 2 menu items:
"Check Out" and "Delete File".
More than this at "::InvokeCommand(LPCMINVOKECOMMANDINFO pCmdInfo)"
how do I make the difference between what menu item was clicked ?

thanks

::QueryContextMenu( HMENU hmenu, UINT uMenuIndex, UINT uidFirstCmd,
                    UINT uidLastCmd, UINT uFlags )
{
const int size = 4;
const char* menuLabels[size] ={
                         "Check Out",
                         "Check In",
                         "Download",
                         "Delete File"
                         };

int menuItemPosition = uMenuIndex;
UINT menuItemID = uidFirstCmd;
for(int i=0; i<size; i++)
{
     MENUITEMINFO menuItemInfo;
     memset( &menuItemInfo, 0, sizeof(MENUITEMINFO) );
     menuItemInfo.cbSize = sizeof(MENUITEMINFO);
     //menuItemInfo.fMask=MIIM_DATA | MIIM_FTYPE | MIIM_ID | MIIM_STRING;
     menuItemInfo.fMask = MIIM_DATA | MIIM_TYPE | MIIM_ID;
     menuItemInfo.fType = MFT_STRING;
     menuItemInfo.wID = menuItemID++;
     menuItemInfo.dwItemData = menuItemID - 1;
     menuItemInfo.dwTypeData = (LPSTR)menuLabels[i];
     menuItemInfo.cch = strlen(menuLabels[i]);
					
     InsertMenuItem(	hmenu, menuItemPosition++, TRUE, &menuItemInfo );
}

Is it possible for an ActiveX control to access the DOM of the page?

Hi everybody!!

I'm developing a web application that has embedded an activeX control. For some specific purposes I need the activeX to access the DOM elements of the page that contains it, but I don't know if this is possible. So, I need to now: first if this can be done and if so, how I could do it.
Any help or ideas will be appreciated.

Thanks

yes its possible, get IHTMLDocument2 pointer/object and you can access the element info, using several Interfaces provided by IE. look in MSDN for IHTML** interfaces...

Late binding from COM client

Hi I am reading this article:
http://www.ddj.com/cpp/184403558
It says:

Suppose you want to call methods on a COM object or Automation Server, but have no header files, type library (discussed later), or any programmatic information about the object. Late binding is what makes this possible. In fact, with late binding you can even instantiate and use a COM object [2] on a remote machine.

And in his code:

wcscpy(progid, L"comcalc.calc"); <br />
CLSIDFromProgID( progid, &pclsid); <br />
HRESULT hr = CoCreateInstance(pclsid, NULL, CLSCTX_ALL, IID_IDispatch, (void **)&idsp);

While late binding , If we have nothing (no need) about COM object in remote server. How could CLSIDFromProgId work? Something must be registered in client computer before executing this line so we need dll/exe file(server) itself. Am i wrong?

I don't understand how CLSIDFromProgId could work here.
Thanks...

IMHO the above code snippet is executed on the remote machine, where the COM server is registered.

AFAIK has the Outlook COM-API a lot of collections, so can find all objects in the right collection. You got to find the right one (first in the docs and than in your program).

IWebBrowser2 Behavior is Different from IE7 in Vista

Hi,

I've managed to create my own custom web browser using IWebBrowser2. Also, I managed to
configure HostUI things so that the browser uses theme. Now my final problem;

The ajax behavior is different from IE7 even if I use Vista to run my own browser application.
In IE7, when I click link which executes Javascript then "click" sound does not happen, but
my own browser like other customized browsers using IWebBrowser2 or MSHTML, makes
"click" sound and the web application's ajax behavior does not work like IE7.

How can I make my own browser's ajax behavior like IE7? I've created my browser application
using C and I can upload my code if needed.

Has anyone experienced this problem? It seems that as I said before, all other browsers which
uses IWebBrowser2 or IE's engine does show this behavior.

Thanks in advance.

Hi All,
I am currently developing an Addin for Outlook 2000 and have to intercept the Send Mail event. Before sending the mail item I need to modify the Subject line to something other than original and then send the mail. I have tried DispEventAdvise but not with any success. Any pointers/suggestions are highly appreciated.

Somethings seem HARD to do, until we know how to do them.

Sending string from COM to C# under Vista problem

Hi,

I'm experiencing and issue regarding System.AccessViolationException : Attempted to read or write protected memory that occurs since Vista. On XP's or previous, everything run fine. To be more specific. I have a C++ ATL/COM object (created in VS 6) that is wrapped in C# .NET 2.0 . Problem occurs when handling Strings.

I've created COM using standard tools in VS 6.

this is the method definition from Interface IDL file :

[id(9), helpstring("method GetString")] HRESULT GetString([out] LPSTR* word, [out, retval] int* count);

Inferface .h Header file :

STDMETHOD(GetString)(/*[out]*/ LPSTR* word, /*[out, retval]*/ int* count);

Code Inferface.c file :

STDMETHODIMP CLicenser::GetString(LPSTR* word, int *count)
{
     // helper class is some class that provides information that we need...

     *count = this->helperClass.GetCount();  // count works fine anytime.
   
     *word = this->helperClass.GetWord();  // this causes Attemped to read or write protected memory...
     // *word = "some text";  // !!! this works fine, if former line is commented out, this method throws
                                           // no Exception !!!.

     cout << "word:" << *word << endl;  // word is displayed correctly in console window (Console is created by
                                        //C# application) everytime
   
     return S_OK;
}

Method definition in C# wrapper looks like:

int IClassNameObject.GetString(out string);

Anytime this method is called, it finishes properly (also including that Console output word:[whatever word contains]), besides in Vista, it throws that System.AccessViolationException with name of that (GetString) method after it finishes.

Method is Supposed to return a count and fill a supplied string.

If u need I can create sample project / dll , I don't have one now....

From your description, it looks like the problem is with the helperClass member. How does that work?

If not used in any other projects I would strongly recommend that you stick to Automation-compatible types, so here you would use a BSTR rather than LPSTR. .NET understands Automation types better than raw types.

If you can't do this, you need to ensure that the marshalling and memory model are followed correctly. You need to tell MIDL that the parameter is actually a null-terminated string (use the string attribute in addition to out) so that the data is marshalled correctly. Otherwise it assumes that the LPSTR points to a single char.

For returning a string, you must return a new buffer allocated with the system allocator, CoTaskMemAlloc. I suspect what's happening is that .NET is trying to free the returned pointer by calling CoTaskMemFree and in Windows XP, you were getting away with it.

Hi,

I wasn't able to replace LPSTR with BSTR. My knowledge about C++ is limited and I did not find corresponding conversion.

Anyway, I added string attribute and started using CoTaskMemAlloc on C++ side and so far it's working under Vista too, so thank you very much!

Sending array from C# to ActiveX component

Hampus@foi6-Dec-07 20:49

6-Dec-07 20:49

I am trying to send an array from my C# app to an ActiveX component. The array consists of floats and I have used the following declaration:

DISP_FUNCTION(MyCtrl, "SetArrayFunc", SetArrayFunc, VT_EMPTY, VTS_PR4 VTS_I2)
where SetArrayFunc looks like this:

void MyCtrl::SetArrayFunc(float *NewBuffer, short Length)

In my C# app i try the following:

ThisCtrl.SetArrayFunc(ref MyBuffer[0], (short) MyBuffer.Length);
Where of course MyBuffer is an array of floats.

However it seems as though only the first element of the array is transferred.
I have also tried using VTS_VARIANT but that did not work either.

Is there anyone here who has an idea how to solve this?

I would change SetArrayFunc to take an OLE SAFEARRAY. Then you should be able to pass the array directly.

I'm not sure how to do that, simply replacing VTS_PR4 with SAFEARRAY gives me the following error:
"error C2275: 'SAFEARRAY' : illegal use of this type as an expression", so I guess that was not how you meant?

SAFEARRAYs are fairly complicated. You'll need to read a bit of documentation on how to use them. If you don't have the info on your own computer, I think you can look it up on msdn.microsoft.com.

Create safe array of variants where variant elements will contain the floats. Let me know if this helps.

Hi,
I want to create a phone number control. It has text boxes for a USPhone number, an international phone number and international country code. I want it to display the USPhone field and d so in a formatted manner. If the record's Country is blank or "US" or "Canada"...

I think I can create the control. Will I be able to import it into Access and use it on a form that is bound to a table, such that I can bind this control to several fields in the table?

Thanks!
