Hi all,

What can I use instead of the next line character ( \n ).

<code>
StreamWriter^ write = gcnew StreamWriter(holdSMSFileName);
write->Write("\n");
</code>

The \n character causes a problem in notepad.

Thanx in advance

Injecting Windows Application into an SDI View in C++

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

Declaring New type

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 ?

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

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);//i got unhandled exception after completing this statement
}

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.
