You can also use _access().

Dll dialog problem

BeerFizz1-Nov-04 7:48

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");
}

//AFX_MANAGE_STATE(AfxGetStaticModuleState());

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. Mad | :mad:

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.

Calculator Using Stacks

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
