Dialog Box and Custom Controls

[leandrojardim]

I downloaded the hyperlink custom control in John's website but how do I install a new custom control in the dialog editor toolbox? I click on the custom control button and I enter the class name HyperlinkCtrl32 and also link with the correct library hyperlink.lib but it doesnt work. I am using RC2.

Does is possible to use the dialog editor to design a normal overlapped window and after modify its window class and window procedures to make a child window with it?

And what functions and structures I can use to create a custom control and load it in the dialog editor?

Thanks!

Far as I know, you can't add anything to the Dialog Editors toolbox... you have to load custom controls each time. 

Are you including the header (.h) for the control in your resource script?
Are you including the header in your source code (.c) that handles the dialog?
Is there a registration call needed to initialize the control's class name?

Probably... but why would you want to?

I will caution you against over-use of the dialog editor.  It's not really intended as a gui design tool, it's mostly for the creation of pop-up dialogs; child windows that do things like search or ask for passwords and such.  The main GUI for your program is almost always better made in your code... particularly since it's likely you will want the user to be able to resize it.

And what functions and structures I can use to create a custom control and load it in the dialog editor?

Take a look in the "User Contributions" section... There you will find EasySplitter, a custom control for resizeable windows, which includes the source code.

On Johns side there are two hyperlink controls (hlink and hyperlink) both from Alexander Stoica.
From the second it is said: "but this control can also be used from the Pelles C Dialog Editor. "

Load dll before creating dialog for classname "HyperlinkCtrl32".

Code: [Select]

HMODULE hMod = LoadLibrary("HyperLink.dll");for example

Code: [Select]

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpszCmdLine, int nCmdShow)
{
HMODULE hMod = LoadLibrary("HyperLink.dll");
return DialogBox(hInstance, MAKEINTRESOURCE(1001), NULL, (DLGPROC)MainDlgProc);
}

The problem was that I did not use the command "Open custom control" in the Dialog menu.

What could be wrong with this control? It show up in the dialog editor but when I rexecute it within a dialog it blocks the executable program from opening the dialog window...

Code: [Select]

The problem was that I did not use the command "Open custom control" in the Dialog menu.

Can you explain this a little bit more detailed. I can not find what you are talking from.
The help says that there are also dialogs

• new temporary custom control
• rempve custom control
• select custom control

which I can not find too.

The Dialog menu only shows up in the toolbar when you are editing a dialog in the dialog editor. First you must load the dll into memory with that command. After you loaded it, you need to click on the button with a "small head" in the toolbox and select a control from te list.

Man, you did it again! It worked like a dream. How I could not understand that?!
