Hello,
i use this control in dialog based application and i want to assign a CString value to them!
I mean, show html content without calling .Navigate(...);

// sample
CString csHtmlContent = L"<html><body>some very large text</body></html>";
CWebBrowserCtrl2 cWeb;
// here assign CString-value to cWeb!

Is that possible, any suggestion for this problem?
It can be any other control who can show html content!

Thanks for any help!

You can write the HTML text into a temporary file and open that file in your web control using Navigate method by prefixing file:// in its URL.

Some thing like this,

        CComPtr<IDispatch> pDispDoc;
	CComVariant spVar(_T("about:blank"));
	m_Explorer.Navigate2(&spVar, 0, 0, 0, 0); // Just to initialise a blank doc
<br>

	pDispDoc = m_Explorer.get_Document();	
        CComQIPtr<IHTMLDocument2> spDoc(pDispDoc);

	VARIANT *param;
	<big>CComBSTR spbStrHtmlText(OLESTR("<html><body>some very large text</body></html>"));</big>	SAFEARRAY * psfArray = SafeArrayCreateVector(VT_VARIANT, 0, 1);	
	SafeArrayAccessData(psfArray,(LPVOID*) & param);
	param->vt = VT_BSTR;
	param->bstrVal = spbStrHtmlText;
	SafeArrayUnaccessData(psfArray);
	<big>spDoc->write(psfArray);</big>	
        SafeArrayDestroy(psfArray);</br>

See also [IHTMLElement::innerHTML ^]
And have a look at IHTMLDom objects to have more controls over internal html nodes.

The reason it gives you 200 spaces may be because of the field properties you have set in your database. You might have set it as fixed length string field of size 255. Try to make it a variable length string field.

Not possible to set variable length string because database object is return struct variable with fixed length character using pro*C.

suppose i have try to declare structure member variable like character pointer or void pointer when
it return memory leak . I have developed this application using Pro *C language.

ShellExecute(NULL, "open", "pathToYourDocFile", NULL, NULL, SW_SHOWNORMAL);

See info on parameters here: MSDN: ShellExecute[^]

I used the code sent by you but it not opening the document. Below is the code
void CNUITApp::OnHelpUsermanual()
{

ShellExecute(NULL, "open", "C:\\Doc1", NULL, NULL, SW_SHOWNORMAL);
// TODO: Add your command handler code here
AfxMessageBox(_T("Feature not available gg"),MB_OK|MB_ICONINFORMATION);
}

Is your file really called "Doc1" ?

I suggest you use the following line:

Pre Office 2007

ShellExecute(NULL, "open", "C:\\Doc1.doc", NULL, NULL, SW_SHOWNORMAL);

or
Office 2007

ShellExecute(NULL, "open", "C:\\Doc1.docx", NULL, NULL, SW_SHOWNORMAL);

office 2003 is loaded in the system.
I will be giving only the exe to the customer, so we specify the path like this then we need to keep on changing the path where ever the document is copied. How to ovecome with this issue?

enhzflep4-Nov-08 0:57

Just use a relative path.

E.g

AppFolder
|
|--FolderA
|--FolderB
\--Help

if exe is located in AppFolder, and .DOC file is in Help folder:

ShellExecute(NULL, "open", "Help\\YourFile.doc", NULL, NULL, SW_SHOWNORMAL);

if exe is located in FolderA, and .DOC file is in AppFolder:

ShellExecute(NULL, "open", "..\\YourFile.doc", NULL, NULL, SW_SHOWNORMAL);
