The only thing I can think to try, without seeing if the dialog box is doing something strange, is to change changing the parent of the dialog box.

You can try the parent of the ActiveX control:
this->GetParent()

and if that does not work, try the desktop window
GetDesktopWindow()

Did you find a solution for this problem. I have the exact same behavior here. Everything works fine until I want to drag the window around. Then the dialog freezes and only keyboard navigation is possible.

I would really appreciate some hints!

I can't wait to port my app to 64bit but it's in MFC! Will vs2005 support MFC's move to 64bit or is it not even an issue to worry about?

Creating tooltip for TBBUTON in ATL

I have been able to create tooltips for static controls. Now I am trying to create a tooltip for a toolbar button. I have created a toolbar button with the following code:

<br />
TBBUTTON Button;<br />
<br />
TCHAR* pButStatsCaption = _T("Get Stats!");<br />
   int iIndex = ::SendMessage(m_hWnd, TB_ADDSTRING, 0, (LPARAM)pButStatsCaption);<br />
   Button.idCommand = IDM_GETSTATS;<br />
   Button.fsState = TBSTATE_ENABLED;<br />
   Button.fsStyle = TBSTYLE_BUTTON | TBSTYLE_AUTOSIZE;<br />
   Button.dwData = 0;<br />
   Button.iString = iIndex;<br />
   Button.iBitmap = 1;<br />

I then create a tooltip with:

<br />
hwndTip = CreateWindow(TOOLTIPS_CLASS, TEXT(""), WS_POPUP | TTS_ALWAYSTIP, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, NULL, (HMENU)NULL, NULL, NULL);<br />

Finally, I create a tool with:

<br />
   TOOLINFO toolInfot<br />
<br />
   toolInfo.cbSize = sizeof( TOOLINFO );<br />
   toolInfo.uFlags = TTF_IDISHWND | TTF_SUBCLASS;<br />
   toolInfo.hwnd = m_hWnd;<br />
   toolInfo.uId = IDM_GETSTATS;<br />
   toolInfo.hinst = NULL;<br />
   toolInfo.lpszText = "Testing 1 2 3";<br />
   toolInfo.lParam = NULL;<br />
   ::SendMessage(hwndTip, TTM_ADDTOOL, 0, (LPARAM) (LPTOOLINFO) &toolInfo);<br />

However, nothing works. Can anyone please help? Thanks in advance.

MFC Application To Browser

Grahamfff4-Mar-05 10:33

I have been using Visual Studio .Net to develop Windows applications, but was thinking of using Web Pages as part of the GUI; i.e. via a Browser.

I have a general question.

Is it possible to link a Web Browser and a Windows MFC application such that the Browser will request data (Pages etc) but the Windows aplication can share/use this data to record/log data. Or could the Browser be an integral part of the MFC application doing the communications between other computers.

Currently I use MFC to do the application, but would like to use Web pages for the GUI part, I think it might be easier? The application runs scripts, displays data from other PC's etc hence the need (I think) to retain the MFC application.

The Web Server (which may be embedded in the application) will be on any computer that we require data from.

I dont know if this is the correct forum, but any comments suggestions please.

Graham.

It is easy if you use the WebBrowser Control in .Net 2.0. But some advanced customizations(http://msdn.microsoft.com/library/default.asp?url=/workshop/browser/hosting/wbcustomization.asp[^]) are hard to implement even in .Net 2.0
A sample of webbrowser application can be found at http://www.microsoft.com/mind/0798/webbrowser.asp[^]

SDI PROJECT-Creating an INI FILE

jerry1211a4-Mar-05 10:04

Hello,

I want to create an ini file for a SDI project I am working on. At some point I think I need to use:

AfxGetApp()->WriteProfileString(szSection, szWindowPos, szBuffer);

to write to the file. How do I create/name the ini file in the Windows folder?

I will also need to read from it. I want to store the values of all my varibles in the doc file in that folder, when the app is closed.

Thanks.
Jerry

You can use WritePrivateProfileString and ReadPrivateProfileString to go back and forth from an INI file.

Unless every user of your program is going to be an administrator, I would not read/write to an INI file in the WINDOWS folder.
Better to select a folder ALL users would have read/write access to.

binary file stream

I am trying to open a file stream to read a binary file.
The open command is:

ifstream file;
file.open((char*)str , ios::in|ios::binary);
...
char c;
file>>c;

It seems to work fine EXCEPT on some specific values such as decimal 12.

It drives me crazy.
Does anyone know how to do it right?

Keep it simple

Thanks David,

The platform is the visual c++.

I took a small binary file and tried to re-print it with printf ("%d",c);.

Some of the values were missing.

Oded.

Linking property sheets and multiple views ?? how do I ??

ur_unholyness4-Mar-05 7:20

4-Mar-05 7:20

I have an application with multiple views and a single document, and I have them all initialized from the application class's InitInstance function. In one of the views, which is a form view derived one, I have added 4 property sheets dialogs, and their CPropertypage classes etc. etc. to get them to work, and addded a CPropertySheet derived class and added these dialogs using AddPage and stuff, and now it is working properly. Also, I have modified the program in a way that I am able to view all the view windows at once(no dialog to select a view on execution) and these propertypages are also created on the initialization of the application (Modeless sheets). Now the real task of developing thses property sheets was that each page on the property sheets will present a number of options for a corresponding view, like page1 will provide options for view1, page2 for view2 etc. Now how do I link the events, such that for example, I need to call a function in view1, I add a button to page1 of the property sheets, and when I press it, the function is called. Is there a way to do this?

Dynamically Opening Files for Output

ChemmieBro4-Mar-05 7:18

I have a pretty simple logger COM component that I am building right now that simply logs entries to a text file when the "LogEntry" call is made. However currently it only logs to one file and that file is declared at construction.

I am now trying to add both a "public" and "private" functionality.

First, I need to check a conditional that the "LogEntry" is either public or private. If it is public, I do everything the same as I do now, if it is private, I need to log it to it's private file.

I am trying to find a way to dynamically enter into a file.

I have tried this already:
I declared a std::map<string, ofstream=""> object. The string is the FileName.
I decided to use a map to make sure I open the file the first time I log to the private file. I run a .find on the string to see if the file is there.
If the file is there, I log to it. If it is not there, I open the file and log to it, leaving it open for future logging.

None of this is working for me.

Since there will be many different clients using this logger component, I need a way to determine which file to log to as they will all have separate files. Then log to that file. But since I don't know how many clients I will have, I need this to be dynamic.

Any help will be appreciated.
Thank you.

If there is a separate instance of your COM object for each client, then make the handle to the log file a private member of each COM object instance. You will then log to the correct file for each client.

If you also open the log file for exclusive write access, then no other client will be able to open the same log file for writing.

Your public file's sharing should be modified to allow multiple clients to open filehandles and write to it. You should protect the writing process with a mutex or some similar synchronization object so that they don't all actually ever write to it at the same time.

Also , what is the Apartment Model ?
perhaps you can change that and then try using the handle to log file as private member.
