I have a dialog with a webbrowser control (via the CWebBrowser2 class). Now I want to display a html page in the control by passing a string that contains the actual html page. Is this possible? And if so, how do I do this?
|
|
|
|
|
i was never able to get it to accept a string. i have always had to write the page text out to a temp file, then tell the browser to read that file.
-c

It's possible, but it's a little ugly. Here's some code I think I found in the MSDN. I was just poking around with it for a while, not using it in a production environment, so it's not too clean.
USES_CONVERSION;
IDispatch * a_poDisp = c_oWebBrowser.GetDocument();
if( a_poDisp )
{
IHTMLDocument2 * a_poDoc = NULL;
a_poDisp->QueryInterface( IID_IHTMLDocument2, (void**)&a_poDoc );
if( a_poDoc )
{
HRESULT hresult = S_OK;
VARIANT *param;
SAFEARRAY *sfArray;
CString sHtml = ???
BSTR bstr = SysAllocString(A2COLE(sHtml));
sfArray = SafeArrayCreateVector(VT_VARIANT, 0, 1);
hresult = SafeArrayAccessData(sfArray,(LPVOID*) & param);
param->vt = VT_BSTR;
param->bstrVal = bstr;
hresult = SafeArrayUnaccessData(sfArray);
hresult = a_poDoc->write(sfArray);
if( sfArray != NULL )
{
SafeArrayDestroy( sfArray );
}
a_poDoc->Release();
}
}

I found a very easy way to do this. Just insert "about:" in front of the string and pass it as the url in the Nagivate method.

Is it possible to disable the frame, so the user cant resize it anymore?
I have a FormView project, and I dont want the user to be able to resize the frame. I'm not sure how this could be done.

Try this... it's based on a dialog resizing, but it must work in the same way in your environment...
void CDialogResDlg::OnSizing(UINT fwSide, LPRECT pRect)
{
if (!this->bAllowResizing)
{
if (pRect->bottom - pRect->top != 400) pRect->bottom = pRect->top + 400;
if (pRect->right - pRect->left != 400) pRect->right = pRect->left + 400;
}
CDialog::OnSizing(fwSide, pRect);
}hope this helps...

You can just take of the WS_THICKFRAME window style. For example, in MFC override your main frame's PreCreateWindow function and do something like this:
cs.style &= ~WS_THICKFRAME;
You can take off other styles there, too, if you want (like if you don't want them to maximize or minimize the window). Look up "window styles" for more info.

In my CDialog-derived class, I want to call a method after the dialog has been shown, with no input from the user. If I call my method from OnInitDialog, the dialog is not shown until my method returns.
I tried using PostMessage in OnInitDialog to start the method, but the message was not caught. SendMessage worked, but the dialog was not shown before the method call.
Is there a simple way to do this?

PostMessage() is the way to go. The fact that it did not work indicates the message map was not quite right.
#define PM_CHANGE_FLAT (WM_APP + 0x123)<br />
<br />
static const UINT UDM_BLOW_NOSE = ::RegisterWindowMessage(_T("UDM_BLOW_NOSE"));<br />
<br />
<br />
BEGIN_MESSAGE_MAP(CMyDlg, CDialog)<br />
ON_MESSAGE(PM_CHANGE_FLAT, ChangeFlat)<br />
ON_REGISTERED_MESSAGE(UDM_BLOW_NOSE, BlowNose)<br />
END_MESSAGE_MAP()<br />
<br />
<br />
BOOL CMyDlg::OnInitDialog() <br />
{<br />
<br />
PostMessage(UDM_BLOW_NOSE);<br />
PostMessage(PM_CHANGE_FLAT);<br />
<br />
return 0;<br />
}<br />
<br />
<br />
LRESULT CMyDlg::BlowNose( WPARAM, LPARAM )<br />
{<br />
return 0;<br />
}<br />
<br />
<br />
LRESULT CMyDlg::ChangeFlat( WPARAM, LPARAM )<br />
{<br />
return 0;<br />
}

Thanks for your quick reply
Where did CUpdateThread come from?
I would like to have my message responding method within the CDialog-derived class that is posting the message.

Hi, i need to know how to make my app check wether its connected to the internet. I need this cause my app needs to check for updates and i don't want the dial up dialog (for dial-up connections) appearing every 5 minutes. How can i stop it from popping up, so that it only checks for updates when it really is already connected to the internet?
Thanks
Kuniva

calling the InternetGetConnectedState function should not popup a dialup box.

Hi,
Im writing a program in C++, using the windows.h header file to develop an application. Im capturing images from a camera and then saving them in a default folder.
I want to allow the user to be able to browse through their file directories and choose which folder they want the images to be saved to. But, I cant find a simple solution. I would have thought there would have been a defualt control that allowed you to do this. But all the ones I have seen require you to set imagelists and things for the bitmaps to use for the folders.
I would GREATLY appreciate any help with this problem. Ive looked around on msdn, and on this site too. What is the easiest way to do it? Apart from simply asking the user to paste the folder path into a text box.
Cheers for any help

Look up SHBrowseForFolder() in MSDN Library

ShBrowseForFolder is what you are looking for, search around codeproject for samples, and/or how-to.

Thanks to you both for the quick responce 
Ill give it a try.

try this code:
BOOL BrowseForDir(char *cpPathName, HWND hParent)
{
BOOL bRetval = FALSE;
BROWSEINFO sBI;
memset(&sBI,0,sizeof(BROWSEINFO));
sBI.hwndOwner = hParent;
sBI.pidlRoot = NULL;
sBI.pszDisplayName = cpPathName;
sBI.lpszTitle = "Select the folder To Save To:";
sBI.ulFlags = BIF_RETURNONLYFSDIRS;
sBI.lpfn = NULL;
LPITEMIDLIST pidl = SHBrowseForFolder(&sBI);
if (pidl)
{
SHGetPathFromIDList(pidl,cpPathName);
bRetval = TRUE;
}
return bRetval;
}

I have found that some ADO methods (Update, Delete)
doesn't work with tables having high number of fields.
Is this problem real ??
How can I manage big tables with ADO ?
Tanks a lot !

|
|
|
|
Huh!?
Can't be...
What error do you get? Or what doesn't work exactly?

The 80004005 error is generated and the string in the exception is: "Query too complex"
This assertion is generated when I try to update an
existing record or to remove it.
Instead, when I try to add a new record and when I fill
it, or when I browse the big table, none exception is
generated !!!
I really don't know how to solve this problem !!!
