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.)

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.
Hack on...

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

I have a Windows Development course project and my part of the project is to create the event logging module that uses the Windows Event Viewer. I have referenced Windows NT Event Logging By James D. Murray and Programming Server-Side Applications for Microsoft® Windows® 2000 by Jeffrey Richter, Jason D. Clark. These were a big help, but I can't seem to get Event viewer to link to my message DLL. Event Viewer has the logs I create, but when I double click on the event to look at the properties the following message is displayed.
The description for Event ID ( 100 ) in Source ( Logger ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. The following information is part of the event: dfgdfhfd, dfhfdhdsfhdsfh.
"dfgdfhfd, dfhfdhdsfhdsfh" are the two test strings that I passed into the event log that are supposed to be use with the message DLL to produce "Username: dfgdfhfd, Password:dfhfdhdsfhdsfh" in the Description. I have checked the path I set in the registry for the message DLL and it is correct. Does anyone have any insight into what I'm missing?

You have created the message files and compiled them with the "message compiler" (mc.exe)?
You are _really_ sure your DLL containing these messages is in the registry:
HKLM\System\Current...\Serives\Eventlog\Applications\MyFooApp
and that there is a REG_SZ or REG_EXPAND_SZ entry with the name EventMessageFile pointing to your message DLL?
If you are really, really sure this is OK, I think you have to elaborate.

First off,Thanks for the response---I appreciate any help you can offer.
I was going to post my code with my question, but I'm new to this board and didn't see an attachment box anywhere. Is it possible to upload small attachments?
I have compiled the message file using the MC.exe with several different parameters(every source I have found uses slightly different parameter). I then use RC.exe to create the .res file. I then use link.exe to create the DLL from the .res file. I'm not sure any of this is completely correct.
I use a CRegKey object(m_RegistryKey) in a wrapper class I wrote and call my member function below. I have tried #define MY_LOGGER_REG_PATH "SYSTEM\\CurrentControlSet\\Services\\EventLog\\Application\\Logger" and I still get the same description, Logger is just stored under Application instead of EventLog.
#define MY_LOGGER_REG_PATH "SYSTEM\\CurrentControlSet\\Services\\EventLog\\Logger"
void LogRegisterMod::CreateRegKey()
{
// prevents re-creation of registry key if it already exists
// if(this->m_RegistryKey.Open(HKEY_LOCAL_MACHINE,MY_LOGGER_REG_PATH) != ERROR_SUCCESS)
{
// creates or opens(if key already exists) the registry key
this->m_RegistryKey.Create(HKEY_LOCAL_MACHINE, MY_LOGGER_REG_PATH);
// sets the type of event the log supports
this->m_RegistryKey.SetValue(EVENTLOG_WARNING_TYPE | EVENTLOG_INFORMATION_TYPE | EVENTLOG_ERROR_TYPE,"TypesSupported");
// sets the HD path to find the event message DLL/EXE
this->m_RegistryKey.SetValue("C:\\Data\\CodeRock\\CS499\\Logger\\LoggerMessage.dll","EventMessageFile");
// sets the number of catergories in the message DLL/EXE
this->m_RegistryKey.SetValue(1,"CategoryCount");
// closes the registry key
this->m_RegistryKey.Close();
}
}
This is my message file.

That is however how it's intended to be used. You should usually not add any keys to the Eventlog key (since that in fact is creating a new event log!), only its three existing subkeys.
What might be a problem for you, is that according to documentatin the EventMessageFile value must be of type REG_EXPAND_SZ. From your code it seems you're using a plain REG_SZ. This probably isn't a problem in your case since you're using hard-coded paths, but when given the choice to do it "right". 
Another thing to look out for is that (again if my memory serves me) is that you need to add the value ParameterMessageFile (also REG_EXPAND_SZ) for event messages with replacement values. I think this is your current problem.

I have looked at the REG_EXPAND_SZ parameter before and that is used to expand %SystemRoot% to the local machines Root path. I think I have to find an API function to declare REG_EXPAND_SZ because the MFC function specifies REG_SZ automatically.
There are three message files that can be specified: ParameterMessageFile, CatergoryMessageFile, and EventMessageFile. I have added all three and pointed then to the same DLL. According to the books, the DLL can contain all three types in one file. My current DLL only has catergories and events. It gave me the same error message. I have looked at other event log registry values and some have all three specified, some have Category and Event, others have only event. I will try this again. The books say how important Logging is, but I haven't found a good example of source code that implements logging yet. As important as Logging is, VS 6.0 doesn't have a Message compiler integrated. Logging looks like it was added as an afterthought.
