okay, what does this mean?

error C2440: '=' : cannot convert from 'char [2]' to 'char'

I got 25 of these for that code.

"b" is a character string of length 2. If you want just the character 'b', then use single quotes.

Piping stdout to text box

Leo Smith21-Jan-02 6:08

21-Jan-02 6:08

I have what may be a simple question. I have a couple of DOS apps that I would like to have a Windows Front-End for. I know how to launch the apps from the windows app, but I want the output to be piped directly into text box (or something like that), instead of sending it to a text file then reading the text file one line at a time. Is there a simple way to capute or redirect the screen output to a window?

Thanks,

This bit sends cout to a console

<br />
	if( !AllocConsole() )<br />
		MessageBox(_T("AllocConsole failed."));<br />
	<br />
	m_hConsole = GetStdHandle(STD_OUTPUT_HANDLE);<br />
	freopen("CONOUT$", "wt", stdout);<br />
	cout = new stdiobuf(stdout);<br />

Yes, not that exact registry path but a protected one yes. How can that be done programmatically?

I am not sure if this is really helpful but I guess "if" it's possible
your answer can be found with these functions:
RegGetKeySecurity, RegSetKeySecurity and RegDeleteKey.
Take a look at MSDN.
Sorry if I could not help much!
Good luck!

ShellExecute parent handle ?

Newbie question ....

I want to execute ShellExecute(HWND hwnd,.....
so that I can run another executable while my program is still running.
The first parameter is a handle to the parent window.

Afraid I don't know what/where to use for the first parameter.

Any help would me appreciated! Smile | :)

Chances are passing NULL as the first parameter is OK for your purposes.

Thanks Joaquin,

Using NULL does compile!

I wrote:
int hrtn;
hrtn = (int)ShellExecute(NULL,"open","help.txt","","c:\\",0);

Hmmmm... It returns 42 which seems to indicate that it was successful, but nothing happens. Perhaps I missunderstand this call. I thought it would open an editor as a separate process.

BTW: running NT 4.0 SP5

Best regards,
Robert

You have passed "" as the lParameters parameter, when it should have been NULL.

Ummm... try ShellExecute(NULL,"open","c:\\help.txt",NULL,NULL,SW_SHOWNORMAL) (you know, I don't have my IDE handy to try these things out).

BINGO ! Yes it works. Pops right up as a separate process.

CEditView selection and modification

I was wondering about CEditView.

I'm having problem to making selections within a CEditView and how to modify the text in it. I'm also wondering how to make a control for it and how to get/modify the text in it.

Thanks in advance ...

CEditView::GetEditCtrl gives you access to the underlying CEdit control. On this control you can use the methods CEditView::SetSel, CWnd::GetWindowText and CWnd::SetWindowText.

I was wondering how I can have 2 or more new documents open by default each time my MDI application starts (instead of just 1).

In the InitInstance of your app, you can make a call on the document template that you registered to create a new empty document. Do this right at the end on of the InitInstance procedure:

pDocTemplate->OpenDocumentFile(NULL) ;

Stan the man21-Jan-02 2:03

21-Jan-02 2:03

I am trying to develop an edit box that can take input and whne you push "return" it will automatically send the text as ... to the View. Now, I would like to be able to use somethinmg similar to Updatedata to do this but just for this EDIT box. But I want a simple way to do this so that I don't have to post a message specific for this (and every other edit box) and then in the View ready each via a call to GetDlgItem etc.

Any suggestions?

Thanks in advance.

System Memory Management??

Don Miguel21-Jan-02 1:54

21-Jan-02 1:54

Hello,

Does anybody know how to check System Memory from my application, and if it is below some limit, warn the user? To be more clear: I implement a HTTP server, using threads for handling clients requests. Probably my code is not so good, having some memory leaks (?), but, during a time, process couldn't allocate enough memory, and I want to be able to check this, and warning. What kind of memory I shall take care? Is possible to handle this situation?

Many thanks,
Mihai
