I cannot wait for OnDocumentComplete message because I need to run some function with multiple navigations, waiting and DOM processing.

Using OnDocumentComplete is the correct way to do what you need. I don't understand your stated reason that you cannot use it.

I need to do something like this

start:
Navigate()
Wait()
parse page, decide what to do
goto start

the OnDocComplete handler cannot jump back to my function (using also some local variables) and continue.

Your problem is you are using arcane design and code structure. Learn some modern development techniques like Object Oriented Design. In there you will find the solution to your problem.

This is very rough pseudo code. I don't really use goto but there are nested loops and relatively compicated alghoritm implemented in my function so I'd like to keep it as it is without adding some unneccessary synchronisation frameworks (only because of implementation details of IE) which would break readibility of the code. As response to OnDocumentComplete I could only post some messages to my dialog which would be running some pieces od alghoritm and I would also need many member variables to keep state of the function. This would make my code very complicated.
Ok I'll figure something out I just hoped I'll get some tips.

ODC can post a message back to your view window, or set an event, or set a flag, etc. to tell the view that navigation is complete and something else needs to happen.

Convert static lib to import lib/DLL

The WebBrowser is an ActiveX control and so you should be running message pump as opposed to calling Sleep. As another poster mentioned, the DocumentComplete event will be fired when the page loading is complete.

I have a static lib that we no longer can find the source code for. We want to continue to use the library, but have problems with it in the context of Visual Studio 2005. It uses I/O routines that are no longer supported. I would like to build a mini DLL around this library exposing the functions from the library that we use, but I'm not sure how to do this. I have a static library and an include file that contains export statements for the library. I thought about using dumpbin to get the symbols out of the library, but there are a lot of symbols and I'm not sure what out of the symbols I'm suppose to pull for a .def file.

Any one have ideas?

you only need the names (and declarations) of the functions and variables you're going to actually use.... right ?

Correct. The static library is already in use and could be used as is in Visual Studio 6.0. However, with changes made in Visual Studio 2003 and above to remove the _io routines, I can no longer link the static libary directly into VS2005. To solve this I assume that I can create a wrapper DLL/import lib on top of the static lib using Visual Studio 6.0, but I'm not sure I understand what I need to do to accomplish this. I only wish to expose the functions that I use. There are about 40 of them.

here's how i usually do it:

first, create a "DLL that exports some symbols" project in VC6.

for each function you want to export from the DLL, write a function that goes like this:

Whatever_API_return_Type MyDLLFunction1(params)
{
  return MyLibFunction1(params);
}
Whatever_API return_Type MyDLLFunction2(params)
{
  return MyLibFunction2(params);
}
etc.

then write headers for those functions:

_Whatever_API return_Type MyDLLFunction1(params);
_Whatever_API return_Type MyDLLFunction2(params);
...
_Whatever_API return_Type MyDLLFunction40(params);

build the DLL, being sure to set the proper #define flag to turn on function exporting (see the main header file for your DLL project).

then replace all your MyLibFunction* calls with the corresponding MyDLLFunction* call. link to the DLL's static lib, and that's that...

I was trying to avoid this, because I wanted to preserve the function names. However, this seems like a reasonable workflow, I will just cross my fingers that these functions are not used all over the place. Thanks for your help.

Hi
I know that there are some products that convert DLL to lib, but in your case I think you rigth with your idea.

The steps could be the following:

1. Build a new dll project in vs2005.
2. In your stdafx.cpp add #pragma comment(lib,"mylib.lib")
3. Include your .lib header file in the project.
4. Declare the new functions, maybe with new names.

I expect this steps help you

Copy the bytes from the file, up to the byte in question, into a temporary file. Then copy the remainder of the file into the temporary file. Close both files. Delete the original file. Rename the temporary file. Make sense?

Yes, it's even safer than an 'in place' solution. Smile | :)

I don't know a direct way.

As workaround, you may enumerate windows and call GetWindowThreadProcessId in your callback.
hope that helps
