How can I set environment variables automatically (e.g. using bat file) without going in Control Panel -> System Properties -> Environment and adding them manually?
Thanks,
Michael

did you try ::SetEnvironmentVariable ?

I think, Michael wants to create constant environment variable, whereas ::SetEnvironmentVariable works only for the current process.

if you say so...

HOWTO: Propagating Environment Variables to the System
ID: Q104011
The information in this article applies to:
SUMMARY
You can modify user environment variables by editing the following Registry key:
HKEY_CURRENT_USER \
Environment
You can modify system environment variables by editing the following Registry key:
HKEY_LOCAL_MACHINE \
SYSTEM \
CurrentControlSet \
Control \
Session Manager \
Environment
Note that any environment variable that needs to be expanded (for example, when you use %SYSTEM%) must be stored in the registry as a REG_EXPAND_SZ registry value. Any values of type REG_SZ will not be expanded when read from the registry.
Note that RegEdit.exe does not have a way to add REG_EXPAND_SZ. Use RegEdt32.exe when editing these values manually.
However, note that modifications to the environment variables do not result in immediate change. For example, if you start another Command Prompt after making the changes, the environment variables will reflect the previous (not the current) values. The changes do not take effect until you log off and then log back on.
To effect these changes without having to log off, broadcast a WM_SETTINGCHANGE message to all windows in the system, so that any interested applications (such as Program Manager, Task Manager, Control Panel, and so forth) can perform an update.
MORE INFORMATION
For example, on Windows NT, the following code fragment should propagate the changes to the environment variables used in the Command Prompt:
SendMessageTimeout(HWND_BROADCAST, WM_SETTINGCHANGE, 0,
(LPARAM) "Environment", SMTO_ABORTIFHUNG,
5000, &dwReturnValue);
None of the applications that ship with Windows 95, including Program Manager and the shell, respond to this message. Thus, while this article can technically be implemented on Windows 95, there is no effect except to notify third-party applications. The only method of changing global environment variables on Windows 95 is to modify the autoexec.bat file and reboot.

It'll be at its best when you just provide KB article ID or link, without copying whole article into the message board.

how can I change the background color of a datetimectrl?
I don't talk about the MonthCalCtrl that's quite easy (MCM_SETCOLOR).I tried to override the function OnCtlColor(EditCtrl...) but it don't work. I also tried it by the wm_paint message itself no chance.
Has someone an idea and can help me?

Hi !
I am trying to use a list control inside a window, not a dialog, so I can resize it. I tried to create a class the inherit from CListCtrl and on it's instance to use the Create function:
CErrReport::CErrReport(CWnd *pParent)<br />
{<br />
Create (WS_OVERLAPPEDWINDOW|WS_HSCROLL|WS_VSCROLL,CRect (20,30,200,300),pParent,1);<br />
<br />
}
On the paret window I used :
CErrReport *perr=new CErrReport (this);<br />
perr->ShowWindow (SW_SHOWNORMAL);
But the problem is that when the window starts I can't even click on it or move it or close it, nothing.....
What am I doing wrong ?????????????????///
Please help me
Thank you

Why not use resizable dialogs?
Alberto
|
|
|
|
|
If I use a resizable dialog, then the dialog itself is resized but the control size is fixed, no ?
If I create a dialog based application, and I click on the maximize button, all the control remian in the original size they were created, is there a way to expand them to the size of the whole dialog frame ?
Thank you
Shay

You should be able to intercept the WM_SIZE and then, for each control in the window, call SetWindowPos or something like that. The WM_SIZE gets called with the new size as parameters, so you can redraw your controls or child window accordingly.

Shouldn't it be created using the WS_CHILD style? All the controls are supposted to be child windows. Just an idea.

Well, I tried to OR inot the style WS_CHILD and it did not help....
Thank you...

How about message reflection? I can't remember if it's nescessary to make the control work properly.

what is message reflection ?

Look at TN062 in MSDN.
Sorry for not elaborating, but I really have to get home now (it's almost 5 pm in Denmark).

I think the style is wrong.
WS_CHILD|WS_VISIBLE| ....
don't WS_OVERLAPPEDWINDOW (WS_CAPTION, WS_SYSMENU, WS_THICKFRAME, WS_MINIMIZEBOX...)

suggestion
CErrReportListCtrl:public CListCtrl
{
};
CErrReport:public CWnd
{
private:
CErrReportListCtrl m_ListCtrl;
public:
CErrReport(CWnd* pParent,CRect& r=CRect(0,0,200,200))
{
Create(pParent,r);
}
void Create(CWnd* pParent,CRect& r)
{
Create(WS_OVERLAPPED|..,...,r,pParent,..);
m_ListCtrl.Create(WS_CHILD|WS_VISIBLE|..,.....,this,1);
}
void OnSize(nType, cx, cy)
{
//Maybe
if(GetSafeWnd()!=NULL)
m_ListCtrl.MoveWindow (0, 0, cx, cy);
}
};
CErrReport *p= new CErrReport(this);
The Listctrl is nested in the CWnd

I will try this one, it looks like it's going to work. I found a similar solution in a book but it was too complicated, yours looks better.
Thank you.

Can someone verify my thinking here - I think that a windows message can only be handled by a window-based class. Is this right?
For example: in a MFC app I can handle a message in the view, mainframe, etc. but I can't handle it directly in a non-window class that the view instantiates. (I know I could always call a function in the other class from the view's handler.)
thanks

Yes, this is true. The exception is WM_COMMAND, which can be handled by CCmdTarget derived classes, like CDocument, CWinApp or CYourOwnCmdTarget.

Thanks, Tomasz. I thought that was right, but sometimes it helps if you can find someone else that agrees.

If you really need to provide message handling stuff in classes not derived from CWnd, you may want to use CSubclassWnd by Paul DiLascia (the guy who writes C++ QA column in MSDN Magazine). Just search for CSubclassWnd in MSDN.
