I have been tasked with writing a Windows Application that needs to manage multiple processes. The application needs to layout the users main screen by placing the Windows frames of each application/process at specific locations defined in either the registry or some kind of INI file. My first thoughts are to construct an SDI C++ application with Multiple Views for each process that I need to manage.
Does anyone know if it is possible to inject into a View a application process.
Thanks for your time.

please elaborate... u want to add a CProcess to CView???? I think i have done this.. i mean the thing u want to achieve but not CProcess in a CView!!!! this is absurd i think
|
|
|
|
|
Yes,
I think that to add CProcess to CView is something that I would like to try. So that I can have multiple views in my application each one displaying a different Windows process. I can then switch between each view and therefore each individual process.
Many Thanks,
Alan

I want a new data type which is essentially a float that is something like
<br />
typedef float LogData;<br />
However when i assign a float to LogData without explicit cast, i want the compiler (VS.net 2003) to signal a warning. Is there any way to do this? i just want to make sure that i accidently dont use the wrong "data types" in the wrong places. Thanks.

In fact, there won't be any warning because the two types are exactly the same ! I don't understand why you want to have a warning...
Even if you accidently use a float instead of a LogData, there won't be any problems because they are exactly the same. So, what's the problem ?
|
|
|
|
|
Yeah i guess i was getting a bit paranoid about type's. Thanks .....

Why would you want LogData ld = (LogData) 5.0 instead of just LogData ld = 5.0?

How can i browse for for particular type of files, when i use CFileDialog object for selecting files my application crashes,is there any other functionality for browsing
files?
|

|

When i browse for file, after selecting i got Microsoft, error which popups one dialog box which send, dont send, debug buttons, when i tried to debug i got unhandled exception error

How to declare CFileDialog?
|
|
|
|
|
CFileDialog thinly wraps the windows file dialog control. Nearly every app I've seen uses it's
functionality or extends it.
It's got alot of settings, including how you give it a list of file types to browse for.
WELL documented!

Instead of finding other crazy solutions, why don't you simply debug your program ?
If you are stuck (after using your debugger to locate the problem), you can still post some relevant code here, with a detailed explanation, so that we can help you.

When i debug the application i got unhandled exception error msg
my code for browsing files is..
static TCHAR BASED_CODE szFilter[] = "Windows Setup file (*.exe; *.EXE; *.msi ;*.MSI)|*.exe ;*.EXE;*.msi;*.MSI||";
CFileDialog oFileDlg(TRUE,"exe","",OFN_FILEMUSTEXIST|OFN_NOCHANGEDIR, szFilter);
oFileDlg.m_ofn.lpstrTitle = "Select the Installable Application";
if(oFileDlg.DoModal() == IDOK)
{
m_strSetup = oFileDlg.GetPathName();
GetDlgItem(IDC_SETUP)->SetWindowText(m_strSetup);
}
Now can u help me

So, it has nothing to do with the File Dialog. Did you check with the debugger what was returned by GetDlgITem(IDC_SETUP) ? And also what was contained in m_strSetup ?
Chances are that you have a memory violation (that would be nice to explain what you get when you have an exception), probably because GetDlgItem(IDC_SETUP) returns NULL.

Does the IDC_SETUP control exist at this point? Step into the code using the debugger.

Are you sure IDC_SETUP is a valid control?

The "crash" doesn't mean you are using the wrong function, it just means you are using it incorrectly.

Hi,
AfxGetMainWnd()->SendMessage(WM_COMMAND, SetCursorPos(r.x,r.y))
The above code works fine
but
CPoint r;
AfxGetMainWnd()->SendMessage(WM_COMMAND, SetCaretPos(r));
doesn't work since SetCaretPos is a void function.
so how do I sendmessage for SetCaretPos(r)
Thanks

Those aren't messages they are APIs - part of Windows.
Call them directly anywhere:
SetCursorPos(r.x,r.y);
That's it.
Read up on the caret....it's a little more involved. There's only one caret for the system.
|

|
|
|
SetCaretPos and SetCursorPos are functions you dont need to use SendMessage

Hi,
Thanks for the reply
I realised my mistake.
