PROBLEM: WHEN I CHOOSE NEW WINDOW FROM THE MENU, I DO GET A NEW SET OF CFORMVIEWS, I CAN SWITHC BETWEEN THE TWO NEW FORM VIEWS, BUT WHEN I CLICK ON ONE OF THE PRE-EXISTING FORM VIEWS, I GET AN ERROR, IT'S DESCRIPTION IS SOMETHING LIKE ASSERT(isChild(CRuntimeClass *p).

I want sth like: after I click 'ok' on a messagebox, a IE window (Doc/View)pop up. However, I don't want to use shell comment to call a compiled execuatable file from a Dialog based application, I want Doc/View and Dialog be within the same project because there will be some parameter passing staff. by the way, I don't want the Doc/View to be nested inside the Dialog as Mr. Guenego's http://www.codeproject.com/docview/dfv.asp
anybody has idea?

You can do this by creating a normal doc/view app and display the message box in InitInstance of the app class.

Hi.
I want to use the function "PostMessage" to post a message to a dll from other dll. But I dont know whether it can be realized.

to a dll or to a class or window which is contained in a dll
and your dll is loaded when your app loads presumably?

hi,
I want to post a message to dll. in the dll there is not window or dialog.

Unless there is a window with a message loop in your dll, then PostMessage would be useless.
Perhaps you should describe what you are wanting to do.

PostThreadMessage() will post a message to a thread that has a GetMessage() loop running.

Thank you for the reply.
Do you tell more details about PostThreadMessage or any source codes?

No. You'll either need to call a function in the other DLL, or use some other form or IPC.

I’m trying to use Wininet to access web pages. If I use InternetOpenUrl, I can access a stock quote off of Yahoo. If I try and use an alternative involving HttpSendRequest, I get an “object not found” error. I have tried different ideas for the Open Request, but with no success....
What am I doing incorrectly?
// the code here in “OnButtonUrl” works
void CHttpAppDlg::OnButtonUrl()
{
HINTERNET hOpenHandle, hConnectHandle, hResourceHandle;
CHAR lpszBuffer[256];
DWORD dwRead, dwFlags, dwStatus;
CString strStatus;
CHttpRequestDlg dlg;
if (IDCANCEL == dlg.DoModal()) return;
m_strResult.Empty();
// Initialize WinInet and create the Internet session
hOpenHandle = InternetOpen("HttpApp/1.1", INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0);
if (!hOpenHandle) return;
hResourceHandle = InternetOpenUrl(hOpenHandle, http://finance.yahoo.com/q?s=intc",NULL,0,0,0);
if (!hResourceHandle)
{
InternetCloseHandle(hOpenHandle);
return;
}
if (!QueryInfoStatusCode(hResourceHandle, dwStatus))
AfxMessageBox("Error in QueryInfoStatusCode");
else
{
if (HTTP_STATUS_OK != dwStatus)
{
CString strMsgFormat("HTTP Status Code: %d, Reason: %s"), strMsg;
if (!QueryInfoStatusText(hResourceHandle, strStatus))
strMsg = "Unknown";
strMsg.Format(strMsgFormat, dwStatus, strStatus);
AfxMessageBox(strMsg);
}
else
{
while (InternetReadFile(hResourceHandle, lpszBuffer, 255, &dwRead))
{
if (dwRead == 0)
break;
lpszBuffer[dwRead]=0;
m_strResult += lpszBuffer;
}
}
}
//cleanup
InternetCloseHandle(hResourceHandle);
InternetCloseHandle(hOpenHandle);
//update dialog
UpdateData(FALSE);
}
This code in “OnOK” does not work. It returns a error 404 “can’t find object”
void CHttpAppDlg::OnOK()
{
LPCTSTR lpszAcceptTypes[] = {"Accept: */*", NULL};
HINTERNET hOpenHandle, hConnectHandle, hResourceHandle;
DWORD dwError = ERROR_INTERNET_FORCE_RETRY, dwErrorCode;
CHAR lpszBuffer[256];
DWORD dwRead, dwFlags, dwStatus;
CString strStatus;
CHttpRequestDlg dlg;
BOOL result;
if (IDCANCEL == dlg.DoModal())
return;
m_strResult.Empty();
// Initialize WinInet and create the Internet session
hOpenHandle = InternetOpen("HttpApp/1.0", INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0);
if (!hOpenHandle) return;
// check to see if the user wants to use SSL
dwFlags = (dlg.m_nPort == 443) ? INTERNET_FLAG_SECURE : 0;
// establish the connection with the HTTP server
hConnectHandle = InternetConnect(hOpenHandle, "www.yahoo.com",
80, NULL, NULL, INTERNET_SERVICE_HTTP,0,0);
if (!hConnectHandle)
{
InternetCloseHandle(hOpenHandle);
return;
}
// create the HTTP request
hResourceHandle = HttpOpenRequest(hConnectHandle,"GET","http://finance.yahoo.com/q?s=intc",
"HTTP/1.1", NULL,(LPCTSTR *) &lpszAcceptTypes,0, 0);
if (!hResourceHandle)
{
InternetCloseHandle(hConnectHandle);
InternetCloseHandle(hOpenHandle);
return;
}
// keep sending until authentication is successful
while ( ERROR_INTERNET_FORCE_RETRY == dwError)
{
result = HttpSendRequest(hResourceHandle, NULL, 0, NULL,0);
// dwErrorCode stores the error code associated with the call to HttpSendRequest.
dwErrorCode = result ? ERROR_SUCCESS : GetLastError();
dwError = InternetErrorDlg(GetSafeHwnd(), hResourceHandle, dwErrorCode, FLAGS_ERROR_UI_FILTER_FOR_ERRORS |
FLAGS_ERROR_UI_FLAGS_CHANGE_OPTIONS |
FLAGS_ERROR_UI_FLAGS_GENERATE_DATA,
NULL);
}

Try:
hConnectHandle = InternetConnect(hOpenHandle, <code>"finance.yahoo.com"</code>, 80, NULL, NULL, INTERNET_SERVICE_HTTP,0,0); and
hResourceHandle = HttpOpenRequest(hConnectHandle,"GET", <code>"/q?s=intc"</code>, "HTTP/1.1", NULL,(LPCTSTR*) &lpszAcceptTypes,0, 0);

Yes, it works. I was also able to do a "POST" which is what I was after in the first place.
Thanks so much for taking the time to read and answer my question.

Hi there,
I've read articles on how to create tooltips for buttons and other objects but nothing on just plain text. I would like to create tooltips for my submenu items on the IDR_Mainframe. How can I go about doing this?
Thanks!

I'm currently in the process of adding Unicode support to a website that acts as a file repository. Users are able to upload/download files to this site via http or webdav. Currently, if a user uploads a directory to the site, we use a 3rd party activex component from Software Artisans that creates a zip file archive of the folder on the client workstation, then uploads, and unzips the archive on the server side. I'm currently adding unicode support for our Japanese, Korean, Chinese, etc users. I've discovered that the zip archive component that we use, has very weak support for unicode filenames & foldernames. It appears that it's not unicode aware, but relies on code page conversions. If both the user workstation and the server are running the same default codepage, the zip archive process works fine. If the two are not the same, the files are corrupted upon unzipping.
Looking around, from what I can tell, WinRar is the only archiver that appears to be unicode aware. Unfortunately, there don't appear to be any 3rd party activex components that are capable of creating a rar file. And Rar Labs doesn't appear to have a developer sdk.
Does anyone have any ideas, or know of any examples I can look at regarding adding support for creating unicode aware file archives? Are there any other file archive formats that are unicode aware besides rar? Is tar capable of archiving unicode filenames?

Thank you, thank you, thank you! This is exactly what I'm looking for, and initial testing shows that it does support unicode. I should have come here looking for tips much sooner!

All,
I am trying to use the Picture Control tool from the toolbox to add a picture to my main display window. The picture would be a small box located to the right of text string. When I create the picture control, there is an "Image" field whose description reads as follows:
Image: When Type is Icon or Bitmap, specifies the identifier of the image to use
So, I set the Type filed to either Icon or Bitmap. But, I am unable to enter a file location of the image that I would like to load. When I enter the string C:\Red Button.bmp into the Image field it comes back with the error:
The identifier contains illegal characters
The bigger picture here is that I have a list of voltages and temperatures being displayed numerically. Next to each one I would like to display either a green, yellow, or red small rectangle to indicate whether the engineering readings are ok or need some type of action. I thought I could just use the picture control to put up pictures of solid colored rectangles, and that the code might be able to change these on the fly somehow.

why don't you just draw a rectangle and specify the color of the solid brush depending on what the reading is?
If it's broken, I probably did it

I'm working in Visual C++ (non-MFC). All the information in the help structure seems to show Visual Basic examples. Can you point me to a help topic that would show me how to do what you are suggesting? Yes, if I can call a routine that draws a rectangle of a certain size and color on my main display, that is all that I need to do.
