I'm using a list control with the LVS_EX_CHECKBOXES style. Is there any way I can disable this control, or make it read-only, such that the checkboxes cannot be un/checked, yet I can still use the scroll bar?

Thanks.

I did this on a project a few years ago, let me see if I can remember the details.
1. The check boxes are implemented using a state image list, so you'll need to make your own image list that has the check boxes in a disabled state.
2. When you want to disable the check boxes, set your image list as the list control's new state image list
3. Handle the notification that you get when the user clicks on a state image, and eat the message so the list control doesn't see it and toggle the check box.
4. When you want to re-enable the check boxes, swap the image lists back.

IDE .rc file trivia question

I mainly work in Visual C++ 6.0 and Embedded Visual C++ 4.0 (very close to VS 6.0). From time to time, the IDE will elect to change the definition of a dialog (seemingly at random but I doubt that).

before:

IDD_VERSIONS DIALOG DISCARDABLE 0, 146, 585, 292

after

IDD_VERSIONS DIALOGEX 0, 146, 585, 292

I've seen the IDE change it in both directions. Any ideas as to what exactly DISCARDABLE and DIALOGEX mean? Any ideas as to what is causing this? I have never seen any impact...

Curious.

It's the replacement for DIALOG. See here for more.

DISCARDABLE does nothing in 32-bit Windows. It's there for backward compatibility.

Are you trying to rename the identifier, like from IDR_MENU to IDR_CONTEXT_MENU? If so, can you not just type over the old identifer in the GUI, like we did on 6.0? Or maybe you already tried that and that is why you are asking? Blush | :O

May have to resort to changing the RC and .H files directly if that fails...

Peace!

After adding a new menu resource it's ID is IDR_MENU1. If I select the menu in the Resource Tree I can change the ID (Name) in the Properties window.

Not sure that is what you are looking for. Cool | :cool:

Creating Dialog Problems

I have a legacy system that I want to add a new dialog to. Whenever I create the new dialog through the resource tab, it creates my .H file in the 'externals' directory. Even if I move it from the exeternals directory to it's normal place with the .CPP, I still get errors that it can't find the IDD_DIALOG even though I have included the resource.h header file. Anyone have any clues as to what is happening? This is drivig me crazy! BTW, this is VC++ 6.0

Thanks

waiting for webbrowser::navigate

I'm hosting web browser control in my MFC dialog application (modified di lascia's CHtmlCtrl).
I need to Navigate to some url and wait for browser to complete and after this do some actions.
I'm using this code:

m_html.Navigate(url);

MSHTML::IHTMLDocument2Ptr doc;
doc = m_html.GetHtmlDocument();

while(1)
{
    if (!_tcsicmp(doc->readyState,"complete"))
        break;
    Sleep(200);
}

but it never break the loop. I think it's because IE is in the same thread and
I have to precess it's messages or something. How to solve this?
I've tried to implement some GetMessage/dispatch message calls in my loop but it didn't work.
I cannot wait for OnDocumentComplete message because I need to run some function with multiple navigations, waiting and DOM processing.
Anybody have experienced this? Is it normal IE behaviour or am I missing something?
Thank you.

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.

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.

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.

Convert static lib to import lib/DLL

MR MAB9-Jan-07 4:16

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 ?

Re: Convert static lib to import lib/DLL

MR MAB9-Jan-07 5:44

MR MAB

9-Jan-07 5:44

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
