I am writing a class to create our own toolbar in Win32. For Dialog boxes I create a dialog template dynamically and then call CreateDialogIndirect. I want to create a toolbar with the WS_EX_TOOLWINDOW style set, so that the caption and system menu are the smaller size. Am I right in thinking that this means I need to create a *window* with this style, draw the background grey and then add my buttons ? This is a major pain as it means I can't inherit from my dialog class....

Dialogs can certainly have the WS_EX_TOOLWINDOW style. Are you trying this and it's just not working?

It doesn't work if I set the style to include this value, but using SetWindowLong works just dandy - I was about to post and say I'd got it working 
I have another problem though - I am currently creating a lot of windows that all have their own 'button' on the status bar, but when I click on some of them they are not shown. I tried handling WM_SHOWWINDOW, to find it's not being called. Can you suggest what I might need to do to fix this ?

How is what you want different from the edit box and rich edit control provided by the resource editor ?

Hi,
Am using an owner drawn list control, and I handle the WM_MEASUREITEM message to set the item height. Problem is, this message is sent only when a window is created (or so the MSDN documentation says). I'd like to set the item height, in response to user button clicks (to provide for the effect of zooming items)-this would let the user increase or decrease item heights by clicking buttons. Problem is, as noted earlier, the message is sent only when the list control is created-how do I set the item height, without destroying and creating the control again?
Any help is much appreciated.

The fact that there is no way to set an item's RECT and that ListViews only supports LVS_OWNERDRAWFIXED leads me to believe that you are, unfortunately, out of luck...
Unless, you only have one column in the ListView in question, then might I recommend moving to a ListBox instead... its WM_MEASUREITEM suffers the same problem ( only ever getting called once ), but you can set an items RECT at runtime ( like when the user clicks on it ).
void CMyZoomListBox::OnSelchange()
{
if ( -1 != m_nLastSelection ) {
SetItemHeight ( m_nLastSelection, m_nNormalSize );
}
m_nLastSelection = GetCurSel ();
SetItemHeight ( m_nLastSelection, m_nZoomSize );
Invalidate ();
}

I asked this same question for SendMessage HERE once before. However, it appears as though the solution for SendMessage does not work for PostMessage.
I want to pass a CString as one of the parameters of PostMessage. How is this done?

Well, you can pass a pointer to a CString, however this will work only if the receiver of the message to is in the same process as the sender, otherwise the pointer will be meaningless. You also have to make sure that the CString object exists long enough for the receiver to use it. Since posted messages are handled asynchronously, you'll need to arrange this part yourself.

Assuming the target window is in the same process, you can send a CString via PostMessage like this:
void SendTextToWindow(HWND hwndTarget, UINT uiMessage, LPCSTR lpszText);
{
CString* pText = new CString;
(*pText) = lpszText;
::PostMessage(hwndTarget, uiMessage, (WPARAM)pText, 0);
}
Then, in the message handler for uiMessage,
LRESULT OnSomeMessage(WPARAM wParam, LPARAM lParam)
{
CString* pText = (CString*)wParam;
ASSERT(pText);
delete pText;
return 0;
}
I have used this, but I do not recommend it because there is a potential that the message could not make it to the target window and thus the CString never be destroyed. Also, this only works if the target window is in the same process. Ultimately, if you really need to do this often, I would recommend creating a manager class (something line CStringMessageManager), and have it be responspilble for deleting CString objects created and passed via PostMessage.

I went ahead and posted the code I use to deal with this situation. You can find it at

I wrote a program by dialog project , that works excellent.
Now I need to convert it to DLL.
---------------------------------------------------------
I opened project (MFCAppWizars(dll)).
I attached the recource dialog and all his class (CMainDlg).
I opened also exe project for test the dll and there I wrote:
HINSTANCE hInstance;
hInstance = LoadLaibrary("main.dll");
---------------------------------------------------------
My questions:
1. Where have I write CMainDlg::DoModal() if I want that it wiil shown immidietly when this dll will act ?
2. How can I get and return parameters ???
3. How can I acted this dll from the another exe program ???
------------------------------------------------------
PLEASE !!! HELP ME !!! 
Thanks![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

Do not use LoadLibrary for this case.
In dialog class declaration (header file) put:
#ifdef DLL_BUILDING
#define DllExportImport __declspec(dllexport)
#else
#define DllExportImport __declspec(dllimport)
#endif
class DLLExportImport CMyDialog : public CDialog
...
In project settings of dll add DLL_BUILDING define
The same header, do include in exe project.
(As You can see, this time CMyDialog class will be defined as dllimport).
In link tab (project settings) of exe project, add path (relative or full) to .lib file generated during build of dll.
It will work

Although I dont just understood it.
Thank you!

Create DLL project. In this project, create header file. In this header write:
In dialog class declaration (header file) put:
#ifdef DLL_BUILDING
#define DllExportImport __declspec(dllexport)
#else
#define DllExportImport __declspec(dllimport)
#endif
class DLLExportImport CMyDialog : public CDialog
...
In project settings of dll add DLL_BUILDING define
That's all for now for dll project. Compile and forget.
Let's go back to exe project.Include the header, You have created in the dll.
The difference, is that when building dll, DLL_BUILDING macro will be defined, so DLLExplortImport will be changed by preprocessor into __declspec(dllexport). When building exe project, You won't have DLL_BUILDING defined, so __declspec(dllimport) will be used.
In link tab (project settings) of exe project, add path (relative or full) to .lib file generated during build of dll.
For more information, see msdn and search for dllexport or dllimport.
uki?

An so what's the point about COleDropTarget?
|
|
|
|
|
Why do you need to put it in a DLL?

Does "COleServerItem" have something to do with strctured storage?
Thanks.

To be honest I don't think it's possible on Win2k...

You probably have to replace som input DLL( _very_ dangerous ).
What if the user installs a servicepack?
