Re: How to knew that a NT/2000 User has logon on? - C / C++ / MFC Discussion Boards

The ActiveX is designed to make it difficult for you to use in an application. The pdf.ocx is not the real thing - the actual ActiveX control carries names like pdf42.ocx etc.

However, the class Id for the real ActiveX is

CLSID const& GetClsid()
{
    static CLSID const clsid
        = { 0xca8a9780, 0x280d, 0x11cf, { 0xa2, 0x4d, 0x44, 0x45, 0x53, 0x54, 0x0, 0x0 } };
    return clsid;
}

Use that in the normal CWnd derived class that the wizard will generate for you to hack it!

My problem is that when I try to have Class wizard generate something it reports the error I mentioned in my first post.

I know. This is because the pdf.ocx is only an automation interface OCX for the real pdf ActiveX control.

Use the Class Wizard and select the pdf.tlb, it will generate the Automation interface and empty event interface for you, say CPdf.

You may search your system to find the real ActiveX or use the ClassWizard to generate a wrapper for any simple ActiveX control, then delete everything with the exception of the Create and GetClsid methods.

Replace the GetClsid method with the one I have provided in my earlier reply. Create the window, use GetControlUnknown method to retrieve IUnknown interface, and the IDispatch interface from the IUnknown. Pass the IDispatch interface to the CPdf instance, and use the CPdf instance to control it. It has LoadFile, which you can use to open a file etc.

If it is getting confusing, write to me privately, I will try to help. If interested, I could write an article with sample for CodeProject Wink | ;)

Hi.

I am trying to upload a variable and file thru POST thru HTTP. The script is not getting both. IE works fine and I tried to use same headers as of IE> but still it doesnt work.
I also tried to send one variable thru multipart/form-data. but its not working.
Here is the code for sending one variable.

	CInternetSession session;<br />
	CHttpConnection *http=session.GetHttpConnection("192.168.0.2");<br />
	CHttpFile *pFile=http->OpenRequest(CHttpConnection::HTTP_VERB_POST,"/bluestar/post1.php",NULL,NULL,NULL,"HTTP /1.0",INTERNET_FLAG_RELOAD);<br />
	<br />
	CString sContent;<br />
	sContent= CString(HTML_BOUNDARY)+"\r\nContent-Disposition: form-data; name=\"packet\"\r\r";<br />
	sContent+="Faizan";<br />
	CString sEnding="\r"+CString(HTML_BOUNDARY)+"\r";<br />
<br />
<br />
	sContent+=sEnding;<br />
	CString sPacket;<br />
	CString str; <br />
	sPacket="Accept: */*\rAccept-Language: en\r";<br />
	sPacket+="Content-Type: multipart/form-data; boundary=" + CString(HTML_BOUNDARY)+"\r";<br />
	sPacket+="Connection: Keep-Alive\r";<br />
	str.Format("Content-Length: %d\r",sContent.GetLength());<br />
	sPacket+=str;	<br />
<br />
        pFile->SendRequest(sPacket,(LPVOID)(LPCTSTR)sContent,sContent.GetLength());<br />
	char szData[200];<br />
	int iRead=0;<br />
	while((iRead=pFile->Read(szData,200))>0)<br />
	{<br />
		szData[iRead]=NULL;<br />
		TRACE("Read back is %s\n",szData);<br />
		m_eRec+=szData;<br />
	<br />
	}	<br />
	UpdateData(FALSE);<br />
<br />
	pFile->Close();<br />
	http->Close();

Has anybody done this before using multipart/form-data.

Try this code:

CInternetSession session;<br />
CHttpConnection *http=session.GetHttpConnection("127.0.0.1");<br />
CHttpFile *pFile=http->OpenRequest(CHttpConnection::HTTP_VERB_POST,"/scripts/uploadf.cgi",NULL,NULL,NULL,"HTTP /1.0",INTERNET_FLAG_RELOAD);<br />
CString sContent;<br />
sContent= CString("--7d3335262f08b6")+"\r\nContent-Disposition: form-data; name=\"uploadfile\" filename=\"c:\\dccard.xml\"\r\n\r\n";<br />
sContent+=szXMLDocument;<br />
CString sEnding="\r\n"+CString("--7d3335262f08b6--")+"\r\n";<br />
sContent+=sEnding;<br />
CString sPacket;<br />
CString str_data; <br />
sPacket="Accept: */*\rAccept-Language: en\r\n";<br />
sPacket+="Content-Type: multipart/form-data; boundary=" + CString("7d3335262f08b6")+"\r\n";<br />
sPacket+="Connection: Keep-Alive\r\n";<br />
str_data.Format("Content-Length: %d\r\n\r\n",sContent.GetLength());<br />
sPacket+=str_data; <br />
pFile->SendRequest(sPacket,(LPVOID)(LPCTSTR)sContent,sContent.GetLength());<br />
pFile->Close();<br />
http->Close();

Is it possible to make some change in a small rect part of this bitmap?
not in whole bitmap.Like making that small part transprint or anyother
......effect?

i forgot to tell, bitmap is not resource. I'm loading it

hey,

does anyone know how to insert text into an avi file?
there's a filter that does this, aware motion ... something,
but i wanted to know how to do something like that,
any help would be very ... um, Confused | :confused:

... helpfull Smile | :)

Hi !

I'd like to put a bmp on a button. It is an arrow, so I've drawn this arrow in the ressource editor, using grey for the background, and blue for my arrow.

The problem is, when the user does not use the default Windows theme (with gry windows ...9 or under XP theme), the background of my bitmap stays grey, whereas the rest of the windows has another color. How can I do to have the background color of my bmp be read as "transparent" ? Do i have to manually blit the bitmap everytime the window is being redrawn ??? (I hope not...)

Thanls for the help...

~RaGE();

Why u don't make the background transparent? I thinks its the green monitor button in the icon editor.

Thanks, Mark

Because I have used a bitmap, and not an icon. Roll eyes | :rolleyes:

Let's use an icon Big Grin | :-D

Thanks for the help.

~RaGE();

button->properties->styles.bitmap(click) Smile | :)

button->properties->extended styles.transparent(click)

i hope it will work Smile | :)

no no... i'm not right..
you can make your background transparent in the icon editor...
click the oranje/rose monitor.

sorry Smile | :)

See if this article is of any help.

Hello,
when i like to overwrite data in a file with new data, how i do it?

I have a file where i save the filenames entered in the "save as" dialog window.

Thanks, Mark

Hi,
use "CFile::modeCreate" mode.
It will truncate the file to 0, if the file is already exists(overwrite). Otherwise, it will create a new file.

Hope this helps
regards
~Hari~

Thanks! I haven't found a good howto about CFile in the web yet. Always the same stuff like in the VC help..
