hi all,

I have an ATL activeX DLL, I created my own file extension ( say .xyz) and made regisrty entries for opening test.xyz for the activeX control in the IE.
I objective is to render the contents of test.xyz into the broswer.
I am facing following problem.

How to pass the filename( test.xyz) when you double click on the file into the activeX control to render the file in IE.

I searched on CP but did'nt find anything related to it. may be i was on the wrong way. Can someone help me ?

Thanks in advance,
Abhi

hi all,

Found answer myself. may this be useful for someone.

1. Implement IPersistPropertyBagImpl interface for your class.
2. Override Load Method
Something like this:

<br />
STDMETHOD(Load)(IPropertyBag* pBag,IErrorLog *pErrorLog)<br />
{<br />
   if(pBag == NULL)<br />
	return E_POINTER;<br />
   ATLASSERT(pBag);<br />
   HRESULT hr = S_OK;<br />
   CComVariant  UrlString;<br />
   hr = pBag->Read(L"src",&UrlString,pErrorLog);<br />
   return S_OK;<br />
}<br />

In UrlString you will have the filename of the file on which you have clicked.

Thanks

MoveFile(it0->c_str(), tempFile);
MoveFile(it1->c_str(), it0->c_str());
MoveFile(tempFile, it1->c_str()) == 0);

on the second call to MoveFile everything crashes?

What am I doing wrong???

How does one execute a simple filename swap???

I'm using VC++ 6, Windows XP home

TIA!

How do I print my voice mail?

What is the return value from the first call?

Thats a typo...ignore then == 0

When I say crash...I mean crash...like total application devistation...no error codes...more like an exception

This is a little vague. Does it stop on any particular line of code, like inside the string class?

First, are all the values correct for your strings? I'd be interested to know if tempFile is correct. I'm assuming this is a char[] rather than a stl:string?

Secondly, what about the return values from MoveFile - does the first one return TRUE? If not, what is the value of GetLastError.

How to control execution order

22-Aug-04 16:42

Hi All,

I have 3 files in a project: o.h, green.cpp and blue.cpp.

o.h________________________________________
1: #ifndef __O_H
2: #define __O_H
3: class CO
4: {
5: public:
6: int m_iName;
7: CO() {m_iName = 2;}
8: CO(int i) {m_iName = i;}
9: CO(const CO& c) {m_iName = c.m_iName;}
10: };
11: #endif

green.cpp________________________________________
1: #include "o.h"
2: CO gO1(2);

blue.cpp________________________________________
1: #include "o.h"
2: extern CO gO1;
3: CO gO2 = gO1;

To make sure this project execution correctly, I
must run these files with the order:
...
green.cpp [line 2]
...
blue.cpp [line 3]
...
----------------------------------------------
Expected: green.cpp [line 2] is ran before run
blue.cpp [line 3].

If you have any solution, please show me how I
can do that (in MS Visual Studio C++ 6.0).

Thank you, Confused | :confused:

In this case, the extern keyword will make the linker search other compiled modules for the declaraction of gO1. It will find this from green.obj, and thus make external linkage with this variable.

In the sense of execution order, after the compiler has compiled the modules, the linker must add them in the order green.obj -> blue.obj. Otherwise the generated code cannot resolve the symbol gO1.

In this solution, you are relying on the linker to determine the execution order. To have more control over the execution order, you should specify the main executable function ( int main(void) ), or the starting point function. Otherwise this piece of your code won't do anything.

One final option is to use the #include keyword at the start of blue.cpp to include green.cpp there. In this case, you also need to exclude green.cpp from the build. To do this, click on green.cpp in Solution Explorer, right-click, choose 'Properties' and mark it as 'Excluded from build'. Also, you don't need to include o.h in the blue.cpp anymore, as green.cpp already does that.

Thank you very musch.

That means we can not use MS VC++6.0 IDE to configure to
solve this problem?

It is ease to solve it by using link.exe in command line.
But I don't known why we can not use MS VC++6.0 IDE to solve it.

Can I hook the OnNewWindow event without BHO?
Because if you use the BHO,you must write information in the register. But I don't want to write information in the register.

Confusing Mouse Operations

radiox22-Aug-04 15:04

22-Aug-04 15:04

Just a quick question,

In my code I'd like to pick up a mouse click. I have this in my message map:

ON_WM_MOUSEWHEEL( )
ON_WM_LBUTTONDOWN( )

and these functions defined:

BOOL CMainFrame::OnMouseWheel( UINT nFlags, short zDelta, CPoint pt )
void CMainFrame::OnLButtonDown(UINT nFlags, CPoint point)

OnMouseWheel gets called and works fine, but OnLButtonDown never gets called.

Am I missing something terribly obvious here?

thanks in advance

Thank you Ivan!

That´s exactly what I want, but my member variables are from typ double (str is a string), so I have got problems. In addition I don´t know where I have to place my function m_sB = 1.56 * m_sA.

Sorry, I am new in C++.

Re: dialog, edit control - No.2

Ivan Cachicatari23-Aug-04 8:05

The expresion m_sB = 1.56 * m_sA, must be numerical values no strings.
In this case create new button control on your dialog and add click event for this control:

void CYourDialog::OnButtonClick()
{
 if(UpdateData())
 {
  m_dVariableB = 1.56 * m_dVariableA;
  UpdateData(FALSE);
 }
}

The m_dVariableB and m_dVariableA must be double(or any numerical type) and declared width classwizard.

Use the hungarian notation to identify and declare variables.

GDI Objects in Windows Task Manager

Jörgen Sigvardsson22-Aug-04 9:18

Jörgen Sigvardsson

22-Aug-04 9:18

I was looking at the task manager to see if I was leaking anything in my app. I saw GDI Objects increment when I did stuff. But it didn't decrement as much as it increment when I undid the previous operation.

I quickly created a WTL application using the WTL wizard, executed it and opened the about box. It didn't decrement fully either.

So, my question is; should I worry or is Windows garbage collecting GDI objects for later disposal?

Hi Jörgen,
I'm afraid I can't answer your question, but a tool I find very helpfull for finding leaks and even more so for code profiling is Glowcode at www.glowcode.com[^] Prety sure they have a trial version.
