Re: Parsing the results of an .ASP page from within VC++

If you are using MFC, then you could use the CHttpConnection and CHttpFile classes to retrieve the results of the ASP page. In terms of parsing it, you are then just parsing a text stream, so i can't really help without knowing what it looks like, but it would probably be easier if the ASP page generated an XML document - you could then use an existing parser rather than having to write your own, making the whole process fairly trivial.

Great, thanks. That's exactly what I was looking for. I should have dug around in MFC a little more before posting.

Changing an Edit boxes height?

Is it possible to adjust the height of an edit box so that it is only as tall as the text?

It's taking up valuable real-estate!

One solution is SetWindowPos(). Use GetTextExtent() to get the text height and width.

Can someone walk me through this?

Here is one possible solution. Do try it out first to see if it works because I have not tried it.

CFont x = GetDlgItem(IDC_EDIT)->GetFont();
LOGFONT z = x.GetLogFont();
CSize height = x.lfHeight,
weight = x.lfWeight;

see CreateProcess, WinExec and spawn. or see "system" if you want to launch from a shell.

you can call FindExecutable() which returns you the executable file's path associaated with the given file.

then call shell execute on that Smile | :)

Try this one - for starting the executable associated with file and wait until the exec. is finished.

	SHELLEXECUTEINFO si;<br />
	memset( &si, 0, sizeof(si) );<br />
<br />
	si.cbSize = sizeof( SHELLEXECUTEINFO );<br />
	si.fMask  = SEE_MASK_NOCLOSEPROCESS;<br />
	si.lpFile = szFileName;<br />
<br />
	BOOL bRet = ShellExecuteEx( &si );<br />
<br />
        if( bRet && si.hProcess )<br />
	{<br />
		// wait for process to end, process handle is stored in<br />
		si.hProcess<br />
	}<br />

hope this helps

Are you talking about the .net Framework or MFC ? I Assume it's for .net

There's no visual GUI builder for VC++.net yet, you need to do it by hand in the code.

Is DLLMain required?

Jawache27-Mar-03 6:55

27-Mar-03 6:55

I'm trying to convert some static libraries we have to DLLs. I'm trying to keep the code as portable as possible so I really would not like to use any windows headers.

1) Can I just leave out the Dllmain function and just use
delspec(dllimport/export) etc... for the class declarations.

2) Is it possible to just change some project settings to covert a project from a static library to a dll? (I remember in my makefile/*nix days all i had to do was change a flag).

Cheers

Have a look at this. It's a pretty decent overview of your DLL options from within VS.

NIC speed?

I'm trying to programmatically determine the current and maximum speeds of the NIC(s) installed in a local PC from VC6. The Net*() APIs don't reveal anything too obvious so far...

Hopefully I won't have to look at registry entries, as the layout of these have changed time and time again from 95 to 2K3...

Any suggestion?

if you want to you can use system("pause") which is just like the DOS command, it will ask the user to press any key to continue, include stdlib.h

HtmlHelp HH_DISPLAY_TEXT_POPUP format

Telefonen27-Mar-03 4:29

27-Mar-03 4:29

I'm using HtmlHelp to display help text as text popup (when pressing F1). Does anyone know if I can have different fonts in a message? Or is just plain text allowed? Confused | :confused:

The help pop-ups in CFileDialog can contain different fonts and images.

This is my code for displaying text pop-ups:

BOOL CMyView::OnHelpInfo(HELPINFO* pHelpInfo) <br />
{  <br />
  static CString theMessageString = "Help message Using different fonts";<br />
  <br />
  HH_POPUP hPop; // HTML Help popup structure<br />
  <br />
  // Initialize structure to NULLs	<br />
  memset(&hPop, 0, sizeof(hPop)); <br />
  <br />
  // Set size of structure<br />
  hPop.cbStruct= sizeof(hPop);		<br />
  <br />
  // Yellow background color<br />
  hPop.clrBackground    = RGB(255, 255, 208);	<br />
  hPop.clrForeground    = -1;<br />
  hPop.rcMargins    = CRect(-1,-1,-1,-1);<br />
  hPop.pt               = pHelpInfo->MousePos;	<br />
  hPop.pszText          = theMessageString;<br />
  <br />
  HtmlHelp(this->GetSafeHwnd(), 0, <br />
    HH_DISPLAY_TEXT_POPUP, (DWORD)&hPop);<br />
  return TRUE;<br />
}
