You'd be amazed how many people didn't know this. I have a whole host of bug reports from testers saying that the shortcut keys weren't working right.

Adding to Nish's response, this is a particular annoying new feature of XP.

You can disable it using XP powertoys I think

It's nothing new to NT5.1, it's been there since NT5.

Hi there,
I recently run into big trouble while mixing ON_MESSAGE and ON_COMMAND handler (nasty assert in Win32-release, but not in Win32-debug). VC didn't complain, eeeks, I'm really glad I found it after hours...
Now I'm confused. May I ask two questions:
1. What is the difference between COMMANDS and "normal" window messages (okay WM_COMMAND is an own message), what is this concept though for?
2. I'm using context menus (sending COMMANDS), plus I'm using build-in hotkeys (now sending normal messages with SendMessage()). How should I combine both, should I send WM_COMMANDS from my OnKeyDown() method?
Thx 4 pointing me into right direction again!

i use createview(), which is memeber function of Class CMainFrame, to create a record-view based on a dialog in a Command-message handler. code as follows:
void CMainFrame::OnViewConfdef()
{
CView *t_pCurrentActiveView = GetActiveView();
CCreateContext *t_pCretContext = new CCreateContext;
t_pCretContext->m_pCurrentDoc = GetActiveDocument();
t_pCretContext->m_pCurrentFrame = this;
CRuntimeClass *t_pRunTC = RUNTIME_CLASS(CHuiYiDefView);
t_pCretContext->m_pNewViewClass = t_pRunTC;
t_pCretContext->m_pLastView = t_pCurrentActiveView;
CView *t_pView = (CHuiYiDefView*)CreateView(t_pCretContext);
if(!t_pView)
{
AfxMessageBox("error!");
exit(1);
}
t_pView->ShowWindow(SW_SHOW);
t_pView->OnInitialUpdate();
SetActiveView(t_pView);
RecalcLayout();
delete t_pCurrentActiveView;
}
The class CHuiYiDefView is derived from the class CRecordView. And the class CHuiYiDefView is linked with a dialog recource.
The following code "enum { IDD = IDD_CONF_DLG }" is added by AppWizard.
I face a problem that the pointer t_pView returned by createview() equals to NULL after I place the controls, Microsoft Ado Data Control and Microsoft DataGrid control, onto the dialog.
All codes i write pass the compile and have no errors. But I cant create the view correctly.

How Do I send a window message to another window that I have no source or control over to maximize?
Here is what I have so far.
In PretranslateMessage I
catch the F10 key and
BOOL CTestCapTabDlg::PreTranslateMessage(MSG* pMsg)
{
BOOL bMsgHandled = FALSE;
switch (pMsg->message)
{
case WM_KEYDOWN:
{
switch (pMsg->wParam)
{
case VK_F10:
// It is easy to substitute another key here but should I use SendMessage(WM_MAXIMIZE,...) to send through the pump? break;
Best Wishes,
Baldwin

You need to capture the respective window handle (HWND) so that you can use the ::SendMessage API to send the WM_MAXIMIZE. You can use the EnumWindows to do that... enumarate the windows, discover which one you need, get its handle and send the message.

Yes, I know but I don't always know the name of the application or the contents of the titlebar. I just want to send a message to maximize all open windows.

Hi,
I've installed InstallShield for VC++ 6
I've made a setup program, but how to
remove an icon when Uninstall runs..
I've created an icon using AddFolderIcon,
but how do i remove, when user presses uninstall.
Please help
Sameer

Icons created by AddFolderIcon are automatically logged for uninstallation (I' ve done it in the past and the icons actually went away on uninstallation.) Is this not working for you?

I want to create a simple G/L program (General Ledger) that can be readily distributed to clients who have no DB applications installed. Where do I begin? I know Access fairly well, and can find my way around a SQL Server system, but my target audience most likely will have neither. I've got MSDE and MDAC, but I don't understand the difference, and a couple of hours browsing through the MSDN documentation hasn't made me one bit smarter. Could someone kindly point me in a sensible direction?
|

MSDE is a cut down version of SQL Server. It is a database in its own right where MDAC is the DLL's and files needed to talk to the various databases.
You'll probably need to install MDAC onto your clients machines. If you want to use MSDE as your database you'll need to install that too. MSDE is a nice database system, much better than Access.

can anyone give me an example of how to use the hidecaret() funtion in a simple text program?
thx,
-ryan
|
|
|
|

If it's CWnd object, simply call the HideCaret() function. If this is a dialog box, you'll have to call it individually for each edit box, means you'll need to sub class them. Moreoever I am talking theory here without having actually tested it. So beware

When you say "a simple text program" I take it that you mean a program having a main(), and in that case you have no business messing about with the GUI.
Specifically, there is no documented way to get the HEND of the console window you are running inside (since you might actually not be running inside a window).

Is this safe :-
(CONST BYTE*)(LPCTSTR)m_str
I am casting a CString to a CONST BYTE* for use with RegSetValueEx(...)
Nish
p.s. It's working fine now! But I just wanted to make sure, it's okay.

Hi Nish. Rest assured, this is perfectly safe (as long as you don't let this pointer live its own life and use it only on calls like the one you're dealing with, but you already know that.)

Thanks Joaquin,
That's what I wanted. Solid assurance. And I got it from you

Nish,
Note that to cast a CString to a (CONST BYTE *) is a safe in this case. Since RegSetValueEx method is looking for a (const BYTE *) and is just going to write the data a byte at a time to the registry, this works.
BUT, this would not be true if a function wanting a (CONST BYTE *) was going to look at it as a BYTE array of text characters. If compiling for a UNICODE release CString characters are 16 bit instead of 8 bit. Remember a BYTE is 8 bit for non-UNICODE and UNICODE both. So this could be a problem in other situations.
Also, note that your cast above would NOT work if you complied for UNICODE and told the RegSetValueEx method that the length of your data was CString::GetLength(). It would return the number of text characters not the number of bytes.
In cases where you want complete compatibility, use the MFC and ATL string conversion macros. See the MSDN article String Conversion Macros.
void CMyClass::HandleString(LPCTSTR szPath)
{
if(szPath != NULL)
{
USES_CONVERSION;
char *s = T2A((LPTSTR)szPath);
...
}
}Nish, I'm sure you already know this, I mainly posted this for any new programmers who might need help with casting.

Thanks for the tips, Jonathan. I was actually using GetLength() and had overlooked the problems that would occur for a UNICODE build.
