No problems. Just make sure you get the parameter types correct in VC++.

Are you saying that the work continues as normal, but that the progress bar just stops?

Hi !
In my app, I'm using a class that I didn't develop (and I have no access to the source code), which implements a linked list where pointers are stored with the type long.
From this list, when I'm extracting a pointer at a specific index, I used to cast it into the needed type, for instance :
Entity* pEntity=(Entity*)MyList->GetPointerAt(3);
But now, I would like to get rid of these old C casts and use the C++ cast. Here is what I did :
Entity* pEntity=static_cast<entity*>(MyList->GetPointerAt(3));
But now, the compiler is rejecting this line, telling that the cast from 'long' to 'Entity*' is not possible.
Anyone could tell me how I should implement this cast with only C++ casts ?
Thank you for your help !
Jerome

You need to use
Entity* pEntity = reinterpret_cast < Entitiy* > (MyList->GetPointerAt(3)); because you are casting an number (your long-variable)into something completely different: A pointer to an Entity-Object.
Static_cast can cast between differnt types of numbers, but you need to get something stronger to cast a number into a pointer. And that is reinterpret_cast.
My opinions may have changed, but not the fact that I am right.

Can somebody explain to me what a callback function is ? is it just a recursive function or have I missed the point?

A callback function is one whose pointer you give to an object or function, and it gets called by the other object or function when a certain condition arises.
For example, the SetTimer() Win32 API function can take a pointer to a function that gets called when the timer period elapses. The function that you pass to SetTimer and gets called is the callback function.
A slightly different example is used with the EnumFontFamilies() function. You pass a pointer to a callback function, and the callback function gets called once for every font that matches the criteria specified in the call to EnumFontFamiles(). In this case, the callback function is called as many times as needed before the EnumFontFamilies() function returns, as opposed to SetTimer() above, where the callback function is called sometime in the future.
Hope this explains it more

Hello,
I have an application and want to add a simple HTML editor to it.
All I need is to allow the user to use bold, underline and italics to standard text - no scripts, activeX etc.
IHTMLView is a bit bulky for my needs and developing from scratch is not an option right now.
Does anyone know of an implementation that I could use, either free or for purchase (preferably free of course).
thanks,

What type of application do you have ?
if it is MDI, you could use two views of your document, one scrollview for editing, associated to a HTMLView for previewing.

Hello,
I'm also looking for a WYSIWYG HTML editor : bold, underline... Very simple. Java does include such a component in its SWING package.
My solution would be to use an ActiveX control but I can't find any. I'm not an ActiveX control but Web components should work fine for a desktop application, am I right ?
Actually I just found : XEditor (120$ !) at http://download.com.com/3000-2403-10184818.html?tag=lst-0-25
Google search for : ActiveX HTML Editor
http://www.itwriting.com/htmleditor/index.php (in C#) : I have no idea how he did it, he used the MS HTML engine !
codeproject search for : MSHTML
http://www.codeproject.com/dotnet/mfchtmledit.asp?target=mshtml
User comments : http://www.azsoft.free.fr/HtmlEdit/HTMLEdit.VC6.zip
I think that last link is the solution to our problem. Check out the demo it's perfect : bold, underline...

When I compile a program, I get a C1083 error message saying that my header could not be found. I checked out the MSDN site and it said I'm missing the C run-time library. How might I resolve this?
Thanks
VC++ 6.0

Missing the CRT library? More likely, your #include directives are wrong, (like using #include <myheader.h> instead of #include "myheader.h") or you haven't set up the include directories correctly (in VC6, that's Tools... Options... Directories, or for your project: Project... Settings... C/C++... Category: Preprocessor)
|
|

|

I've created and added my own header to the project. Why do I need the CRT library at all? I only am using one header file, the one I added.
#include "LinkedList.h"
I'm stuck on this one.
VC++ 6.0

|
|
|

CRT is the C runtime library. It includes the standard C functions, such as printf, strcpy, etc...
Which header can't it open, though? Post the full text of the error message. I still find it rather difficult to believe it's the CRT that causes this.

|

I'm still trying to learn the VC++ 6.0 compiler, it's more challenging than C++ itself. Anywho, I lost my code somehow. I'll see if I can recreate the C1083 error.
Thanks,
Dave

Use LoadLibrary(), same as an application

but if i use the loadlibrary(),i find i can't make it work
properly ,even in a application
a good man in china

Why doesn't it work? I've never had any problems using LoadLibrary() in a DLL or an application. Is the DLL located in the windows system directory or in the PATH?
