thanks very much. I could add it.
Will try working on it.
But a quick question....
i need to plot large number of points say,250,000 points in one attempt.
Will this control handle it? Or will it be slow after say 50,000 point or so...?

I haven't worked with the control much. But I hope that you will be able to use this control upto quite an extent.
Somethings seem HARD to do, until we know how to do them.

I'm working on adding the hot-switching of languages to my app, though I have ran into a few problems. I have created sattelite dlls for each of the translated resources. I create a language selection menu at run time with the help of this[^]article. I am able to update the menu and progress bar but unable to update the main dialog. The dialog is contained within the language dlls and contains many controls (with text). So, after calling LoadLibrary how do you update the main window? BTW this is a non-MFC app.

Well, unless there is an easier method, I stored all the controls text into the string table and created a function to reset the text for each control

I have a MDI application. From CDoc, how can I get a handle on the
active document. I can do this for a SDI application:
<br />
CFrameWnd *pWndMain = (CFrameWnd *)AfxGetMainWnd();<br />
ASSERT(pWndMain != NULL);<br />
<br />
CDocument *pDoc = pWndMain->GetActiveDocument();<br />
ASSERT(pDoc);<br />
<br />
POSITION pos = pDoc->GetFirstViewPosition();<br />
<br />
CView *pView = pDoc->GetNextView(pos)<br />
How can I rewrite this code for an MDI? Please any response
any one can give me will be greatly appreciated.
Sincerely,
Danielle Brina (an overworked graduate student)

MDIGetActive() instead of GetActiveDocument should do it.

Any chance you can show me more code? I cant type:
CDocument *pDoc = pWndMain->MDIGetActive();
because MDIGetActive is not a member of CFrameWnd.
How would you rewrite that portion of code that I
posted earlier for an MDI?
Sincerely,
Danielle Brina

What's wrong with calling AfxGetMainWnd(), which is a global function, followed by GetActiveDocument()?

I have created my own Excel reader which opens and reads the compound files using the ISorage and IStream classes. Everything works perfectly, but I would like to make it a little more user friendly. Here is the code used to open the file:
WCHAR wcFilename[1024];
MultiByteToWideChar(CP_ACP, 0, filename, strlen(filename)+1, wcFilename, 1024);
IStorage *pStorage = NULL;
IStream *pStream = NULL;
HRESULT hr;
hr = ::StgOpenStorage(wcFilename, NULL, STGM_READ|STGM_SHARE_EXCLUSIVE , NULL, 0, &pStorage);
if(FAILED(hr)) {
return 0;
}
When you try to open an excel file with MS Excel, and the file is already in use, it opens it as read only. I want to add the same functionality to my code, but so far I have been unable to. StgOpenStorage always returns with the 'File unavailable' (locked) error. Does anybody know of a method of doing this?

Ehm, remove the STGM_SHARE_EXCLUSIVE flag.  You're telling StgOpenStorage to open the file as read only, but you don't want to share it with anyone. Since the file is already open, you obviously can't be granted exclusive access to it.

I have tried a variation of just about all the flags, none of which work. The STG_E_SHAREVIOLATION is returned for each. After spending quite some time searching the web for an answer I have concluded that there isn't one. However, I am going to try copying the file to the temp directory and opening it from there. This app is a simple reader, the file would not be modified in any way at all.

Creating a temp copy of the file seems to work. For anybody with a similar problem here is the modified code:
if(FAILED(hr)) {
if(hr == STG_E_SHAREVIOLATION ) {
char tmpPath[MAX_PATH];
char tmpName[MAX_PATH];
GetTempPath(MAX_PATH,tmpPath);
GetTempFileName(tmpPath,"TMP",0,tmpName);
if (!CopyFile(filename,tmpName,FALSE) )
return 0;
MultiByteToWideChar(CP_ACP, 0, tmpName, strlen(filename)+1, wcFilename, 1024);
hr = ::StgOpenStorage(wcFilename, NULL, STGM_READ|STGM_SHARE_EXCLUSIVE , NULL, 0, &pStorage);
if(FAILED(hr))
return 0;
}
else
return 0;
}

Does StgOpenStorageEx() work any better?

I have a problem regarding keyboard navigation in child controls of dialog boxes. I have mentioned the style of the child controls to Tab stop while desining the dialog boxes . It works fine when I test the dialog boxes from Layout->Test menu option in Developer Studtio. But when i run the program the keyboard navigation does not work.
Can any one tell me the solution?

If you create your dialogs using the DialogBox API then there is nothing further to do. However if you have modeless dialogs (CreateDialog API) then you need the IsDialogMessage API in you main-message loop.

Hi,
I'm trying to program a custom control using VS2005 MFC AppWizard.
The framework code built by the wizard produces several errors, when I try to built it:
for instance:
IMPLEMENT_OLETYPELIB(CEchoCtrl, _tlid, _wVerMajor, _wVerMinor)
error C2065: '_tlid' : undeclared identifier
error C2065: '_wVerMajor' : undeclared identifier
error C2065: '_wVerMinor' : undeclared identifier
Any ideas how to fix this bug?
Thanks a lot in advance.
Matthias

I've had this happen when trying to add OLE automation support after my project was already created.
I had to use the GUID generator tool, to create a GUID in the IMPLEMENT_OLECREATE format and place something like the following in my Application implementation file. Your needs may be slightly different but maybe this'll help you work out the details. For what it's worth...
// {EF6B41DD-E766-45d8-B731-5923AF4B105A}
const GUID CDECL BASED_CODE _tlid =
{ 0xef6b41dd, 0xe766, 0x45d8, 0xb7, 0x31, 0x59, 0x23, 0xaf, 0x4b, 0x10, 0x5a } };
const WORD _wVerMajor = 1;
const WORD _wVerMinor = 0;
