You can also use _access().

You can also use GetFileAttributes()
You can also use CreateFile and try to open Existing
You can also use FindFirstFile
You can also use CFile
You can also use fopen

Hi,
I have a simple C++.net DLL test app that I am having trouble with.
The test consists of a Dialog style app which (on the press of a button) calls a function inside the DLL, which in turn attempts to open a dialog.
The dialog in the DLL does not open. The constructor is called, however the creation of the dialog returns with a minus one value. I believe this is because the runtime is looking for the dialog resource in the main app and not the dialog. I have tried multiple times to fix this, but have been unsuccessful
Can anyone help?
Below is a snippet of the code with the call to domodal. Thanks.
DLLEXPORT void PopUpaDialog(void)
{
//AFX_MANAGE_STATE(AfxGetStaticModuleState());
AfxMessageBox("Before Popping up the LVTest Dialog");
INT_PTR nResponse = 9999;
LVTest dlg;
nResponse = dlg.DoModal();
switch ( nResponse ) {
case -1:
AfxMessageBox("Dialog box could not be created!");
break;
case IDABORT:
// Do something
break;
case IDOK:
// Do something
break;
case IDCANCEL:
// Do something
break;
default:
AfxMessageBox("Default message after LVTest dialog");
break;
};
AfxMessageBox("After Popping up the Dialog");
}

If my memory serves me well, this is precisely the piece of magic you need so that some GUI inside a MFC extension DLL works all right. Any particular reason why you have it commented out?

Joaquín, thanks for your response.
Well, when I have that line uncommented I get a violation access error atemptign to access location zero in "dlghtml.cpp", at teh lines I have highlighted. Any ideas, or anything I might try?
BOOL CDHtmlDialog::OnInitDialog()
{
AfxEnableControlContainer();
CDialog::OnInitDialog();
RECT rectClient;
GetClientRect(&rectClient);
// if we've been created from the dynamic template
// set the caption
if (!m_lpszTemplateName)
SetWindowText(m_strDlgCaption);
// check if there is a browser control on the dialog
// already
CWnd *pCtrl = GetDlgItem(AFX_IDC_BROWSER);
LPUNKNOWN lpUnk;
if (pCtrl)
{
lpUnk = pCtrl->GetControlUnknown();
if (lpUnk && SUCCEEDED(lpUnk->QueryInterface(IID_IWebBrowser2, (void **) &m_pBrowserApp)))
{
m_wndBrowser.Attach(pCtrl->m_hWnd);
m_bAttachedControl = TRUE;
}
}
if (m_pBrowserApp == NULL)
{
// create the control window
m_wndBrowser.CreateControl(CLSID_WebBrowser, NULL,
WS_VISIBLE | WS_CHILD, rectClient, this, AFX_IDC_BROWSER);
lpUnk = m_wndBrowser.GetControlUnknown();
if (FAILED(lpUnk->QueryInterface(IID_IWebBrowser2, (void**) &m_pBrowserApp)))
{
m_wndBrowser.DestroyWindow();
DestroyWindow();
return TRUE;
}
}

Ummm... I've done a cursory search on the Internet and come up with nothing conclusive. You might want to try moving the AfxEnableControlContainer(); line to your CDLLApp::InitInstance.

Hi,
I have a little problem arranging multiple toolbars in a mfc app.
I have one toolbar and 2 dialogbars we should be placed in ONE row at top of the mainframe. When I say allign top each control gets an extra row => 3.
Than I saw the docking-side-by-side article which works fine, but when I resize the app (smaller) the bars wrap. After sizing back each control has its own row => 3. Another drawback is that floating and rearranging by hand is possible. I want a fixed layout! The user isn't allowed to change the position of the bars!
So, I hope you can help me. I must be a little flag or something but I can't find it. 
Thnx.

I have been trying to open an MFC application in splitter panes. However I cant find any sample project that would show me how to do it.
If anybody could point me to some example that I could use or an extensive example on splitter panes, i'll really appreciate it.

I was wondering if anyone has created a calculator using the stacks and any help would be useful. I guess my biggest problem with it is that I am trying to figure out how to read the data in and get it to how I need it. My teacher will give us an input file to manipulate and her expressions will have a space in between each char. SO what I was doing is using a getline to stop at a space and read all of these in as a char string. Then once I have these I will perform the isdigit to determine whether it is a digit or operand so then I can start converting to Postfix and later evaluating. I am sorry if this is kind of misleadig but I am just mainly having trouble with what I should read it in as and how I should convert it to something that is useful. Please help if at all possible. Thanks Alot

Yes, I did back in college.

Do you still have the source code? I am trying to find an example so that I can get some ideas of how to do mine. Any info or suggestions would be great. Thanks

I'd bet 10 people would give David a stern scolding if he did your homework. What I suggest you to do is post the code that you are having problems with and ask questions about it...

BTW, there are several sources for calculator apps on this site. I doubt they are reading anything from files though...
