On the surface it doesn't make sense, but I recall 'PJ Arends' mentioned something about it in one of his articles, and now I see something similar to it in another article, which is causing me to try and remember the real reason behind its use.
Here's the code.
BOOL CALLBACK CMyApp::searcher(HWND hWnd, LPARAM lParam)
{
DWORD result;
LRESULT ok = ::SendMessageTimeout(hWnd,
UWM_ARE_YOU_ME,
0, 0,
SMTO_BLOCK |
SMTO_ABORT_IF_HUNG,
200,
&result);
if(ok == 0)
return TRUE;
if(result == UWM_ARE_YOU_ME)
{
HWND* target = (HWND*)lParam;
*target = hWnd;
return FALSE;
}
return TRUE;
}
Is there a reason for the reassigning of a value to the same variable in this manner?

You might want to pose this question to Dr. Newcomer.
The only other thing that I can offer is that:
HWND *target = (HWND *) lParam; equates to:
HWND *target;
target = (HWND *) lParam; which is different than:
*target = hWnd;

Your explanation makes a lot of sense and I believe is the reason for what's being done.
Thanks.

I saw that David explaned that it was not a reassignment.
I hope someone knows the anwser to the implied question: What is the reason behind this?
I consider that more important, because I would have just returned the handle to hWnd or 0, instead of returning TRUE or FALSE. It would have been a lot simpler.

Searcher is an EnumWindows callback function. Nowhere in the documentation (that I could find anyway) do you have access to the return value from the callback function. It is only used by the EnumWindows function as a signal to continue or stop the search. The LPARAM parameter however is guaranteed to be consistant through out the EnumWindows process. The idea behind the code is to return the HWND of the found window to the process that called EnumWindows, and it is done through the LPARAM variable.

I think he is Indirectly trying to modify lParam.

Dear All,
I am using the IWebBrowser control as part of my project. My application browses to the internet. Whenever i browse to a certain web site, the url on the address bar does not change to match the current web page.
I am trying to get the current URL using the following method.
CString currentURL = m_webBrowser.get_LocationURL(); (where m_webBrowser is an instance of CExplorer1)
this only works if the url is manually entered in the address bar. however, If a certain web page is pursued through clicks, the above does not give any results.
In a nutshell,
can someone tell me how to retrieve the current URL of a particular web site being browsed ? (in both case, when the url is typed or if resulted from link clicks)
your suggestions would be highly appreciated.
Cheers

Handle the event BeforeNavigate2 of the web browser control..The parameter VARIANT* URL, will give you the url of the page it is going to load....

I had a similar issue. After installing the VS2005 Pro as well as the VS2005 C++ express, I got a package load error each time I started VS2005 pro OR the vs2005 C++ express editon. I uninstalled and reinstalled several times and got the same result. I also tried using the uninstall exectutable from Microsoft to no avail.
Finally I took the following steps:
1. uninstalled EVERYTHING that had to do with Visual Studio, and .NET components (2.0, 1.1, 1.0), SQL Server and MSDN, MSXML. I mean everything. I followed the uninstall directions given in the dialog after uninstalling Visual Studio and removed/uninstalled the items in the order specified.
2. Then I went to the WINDOWS\assembly directory and deleted EVERYTHING under that directory.
3. I went to "Program Files" directory and deleted everything that had to do with Visual Studio and .NET (2.0, 1.1, 1.0) and SQL Server and MSDN.
4. I also went to the following directories and deleted everything and all directories that had to Visual Studio, SQL Server, MSDN and .NET (2.0, 1.1, 1.0)
"Documents and Settings\<username>\Application Data\Microsoft"
"Documents and Settings\<username>\Local Settings\Application Data\assembly"
"Documents and Settings\<username>\Local Settings\Application Data\Microsoft"
5. Finally I deleted all tempory files in all temporary directories and cleared the internet cache and temporary files using IE
6. I also went to "My Documents" and deleted the Visual Studio stuff there.
After all that I reinstalled VS2005 Pro and VS2005 C++ express and I no longer get the errors.

I looked for articles on this before asking a question on this
forum. But...
How can I add a local hotkey to an application only? I want to
add the hotkey CTRL + A and I want it to popup a dialog box.
Anyone have any sample code, instructions, or a simple demo
project?
Please, any response any one can give me will be greatly
appreciated.

I assume you are talking about an accelerator. If so, you first need to add an entry to the accelerator table. Per MSDN:
1) Select the new-item box at the end of the list.
2) Type the key you want to use as an accelerator. The Accel Properties page appears, with the focus in the Key box.
3) Select an ID from the drop-down list in the ID box.
4) Change the modifier and type, if necessary. The modifier specifies whether the key you chose is a combination formed with CTRL, ALT, or SHIFT. The type indicates whether the key is an ASCII or a virtual key value.
5) Press ENTER.
You'll then need to call LoadAccelerators() to load the table. In your message pump, use TranslateAccelerator().

Take a look at RegisterHotKey, UnRegisterHotKey, WM_HOTKEY.

Can you use getchar() for this?

Hi all,
I am Visual C++ junior in the begginer level. I encounter the problem when using some functions built in c file (such as printf("..."); ....) for my project GUI Visual C++ MFC.
ex: when button is clicked then function prinf("..") will be called. But Errors occur when I build solution.
void CButtonTestDlg::OnBnClickedButton1()
{
printf("test printf used in GUI MFC"); // error here.
}
How can I reuse all functions in c file supplied for specific device by manufacture. Thanks

Well, you cannot use printf because there is no standard out in a Win32-based program. You can either use message boxes or change a static text item. You can start by replacing that printf statement with
MessageBox(_T("message box text in GUI MFC"), _T("test"), MB_OK);

Ah, it helps me a bit. Thank you.
But I have a long list of functions and few external c files.
For example:
my dlgfile.cpp in GUI has
void CButtonTestDlg::OnBnClickedButton()
{int num1 = 5; int num2 = 10; int result; int error =1;
result = sum(num1, num2); //error unresolve external symbol "int .."
result = extern sum(num1, num2); //remove above lin , extern error
//extern displayError(error, result); //erro internal compile
displayError(error, result); //error unresolve external symbol "int .."
}
my ExtFile.c has
int sum(int num1, int num2)
{int SUM;
SUM = num1 + num2;
return SUM;
}
void displayError(int error, int result)
{ printf(sum %d \n"result);
switch (error)
{case 1: printf("error 1"); break;
case 2: printf("error 2"); break;
default: printf("error unknown"); break;
}
}
... other function()
Any ideas thanks.
MilkyWay
