Visual C++ :: Resource Editor Failed To Initialize ActiveX
Feb 27, 2014
I'm working on a project which consists of several ocx loaded by one exe. The platform is WinCE. Now I'm on a process to create a new ocx. I do have a copy of those ocx projects in Win32 platform. These Win32 versions were only used to register ocx in local system and then put those on to application dialog by 'Insert ActiveX'.
Now the problem is those Win32 projects are so outdated, and unable to build. Getting too many linking errors to be solved.
I have build the new ocx and link that with exe manually by editing .rc file and all. But still no luck. New ocx is getting registered in WinCE device but failing to start application.
I would like to know in which way is the best to make ActiveX control for video. ActiveX control will need at least show picture and be able to go back in past, change resulation of picture and similar. How complex it is to do something like that? Is MFC best way to make it? Is there somewhere similar code?
I'm writing an ActiveX control. In one of the functions I'd like the user to be able to pass me a pointer to a buffer that they created which I can then fill with data and return a success/error code. What's the appropriate way to do this? I was thinking about just using an OLE_HANDLE type for the parameter and then casting that to pointer inside the OCX but I'm not sure if that's safe or the right way to do it.
I have an SDI / CView app (VS 2010). All works well until I minimize the app using the minimize button or drag it partially off of the screen. In the former instance, any attempt to restore the app results in an appcrash with a tight freeze up of the machine. In the later instance the same happens immediately.
In building the app, I scoured the web for code to accomplish the loading and display of the bitmap. After some experimentation I settled on overriding the OnPaint. Below is the code. Note that m_Map is a CBitmap member and IDB_BITMAP1 is a loaded bitmap resource.
Code:
void CMyDragViewView::OnPaint() { // CPaintDC dc(this); // device context for painting // TODO: Add your message handler code here // Do not call CView::OnPaint() for painting messages // http://msgroups.net/microsoft.public.vc.mfc/loading-bitmaps-into-main-window/563285 int x = m_Map.LoadBitmap(IDB_BITMAP1); TRACE1(" x = %d ", x); CPaintDC* dc = new CPaintDC(this);
[code]....
I suspect that the problem is OnPaint trying to repaint the bitmap which requires reloading it, but I don't know how to work around this.
I have a MFC Com Dll that has a CDialog. In the OnCreate event I create an ActiveX control. The dll is hosted inside an executable of mine. In this scenario everything works fine!
The dll is also called from an external executable and then a Debug Assertion in OCCSITE.cpp occurs when I create the ActiveX control. I suspect that in the executable there is no AfxOleInit. I spend some time with this problem and tried to CoInitialize, OleInitialize, AfxOleInitModule and even AfxOleInit in the dll. But all that does not change a thing. If I understand the mechanics then this is an intended behaviour and should be done in the host exe.
In my executable m_bNeedTerm is 0 and in the external one (where the ActiveX does not work) it is -1. In AfxOleInit this is explained as a special flag to prevent the dll from doing an unnecessary OleInitialize. But as I said even if I call OleInitialize myself I get the Debug Assertion and the ActiveX is not visible.
Is there anything I can do to make the ActiveX control work in the external application? Obviously I cannot Change anything in the application...
We want to generate dynamic resource file for VC++ where the data will come from database (Oracle).
For an example, When a user log in the system, at that time if User is an English User, then some data in english language needs to be loaded in vc++ resource file. If the user is French then French data will be loaded into the resource file.
Right now all the data are hard-coded in the resource file but we want to load it dynamically from database, based on the login-user language.
How to do this dynamic implementation as I am not able to find any such concept in google.
I`m working with MS Visual Studio 6. Trying to connect Word server with my window. This is call server in my class CXContainerView, inherit from CScrollView:
Found an online suggestion of using an rc2 file and cut and paste stuff from .rc file to .rc2 file to see which line causes the problem but don't know how to create a blank .rc2 file. Problem started after I ported from VC++ 6 to VS2010.
I used onctlcolor() method to set the background color for the controls & Dialog. I run my application, working good but after 15 mins the below error occured,
Application Error:
The Required Resource Was --------> Shown message box
Program Error:

what is the reason for that? How can i prevent my project from this problem.
I'm supposed to make a basic text editor using a doubly linked list, I have pretty much written most of it but keep coming across several problems. In certain places,all marked in the code, I get the error "expected a declaration" ive looked online and nothing ive found works. And secondly I also get the error" declaration has no storage class or type specifier" but i havent been able to find anything that works either.
I have an C++ application which uses Microsoft Web browser ActiveX control to launch any URL within the application. The browser is embedded in C++ form and It's working fine with all the feature Microsoft has exposed through Interface(IID_IWebBrowser2).But while any url that is using session cookie has been launched, even after closing the browser the session cookies are not getting deleted. For example if user login info is stored as session cookies,the url is using the cookies and getting launched without asking for user log in info.
But if I close the browser, and again relaunch , the cookies should be deleted and the url will not find the cookies to be used for log in . That is not happening here. Although this is session cookies , it's not getting deleted and being used by embedded browser. However, if the url is launched in IE, it is behaving as expected.
So, Do I need to delete the cookies explicitly? If Yes, How to do that?
Basically, I'm moving a VC project from my Windows 7 build machine to a new build machine that's running Windows 8.1. One of the pre-build steps (for a particular project) runs a script which needs to call the M4 macro processor (which is installed on my C: drive). I've been pretty careful to set everything up the same on both machines (including my PATH) but when I try to build the project on my Windows 8 box, MSVC's IDE shows me this error output when running the script:-
I've created a new dialog in my MFC dialog based application. the new dialog contains 5 control buttons. The following happens and I don't understand why?
1. click on buttonX. (result ok, OnBnClicked message is sent) 2. click on on any place of the application, but not on the dialog.(removing focus from dialog) 3. click again on buttonX (FAILED, OnBnClicked message is NOT sent). but if instead I click on any other button in the dialog (result ok, OnBnClicked message is sent).
And when I do:
1. ... 2. ... 3. click on the dialog area just to set focus on the dialog again 4. click again on buttonX. (result ok, OnBnClicked message is sent) **I need to do step 3 only if I want to click again on the buttonX! why?? I think it related to SetFocus() but I m not sure how.
I've tried different style like, tool windows, overlapped, popup. it happens in all the cases.
Code: class CToolsDlg : public CBDialog { DECLARE_DYNAMIC(CToolsDlg) public: CToolsDlg(CWnd* pParent = NULL); // standard constructor virtual ~CToolsDlg(); CToolTipCtrl m_ToolsTips;
Compilation is success full ,but i am observing that some junk value is there in the path variable. After Reaching If statement cursor went to final return statement ...
I have a method that does some extensive work (retrieves a list of emails from an imap server). What i wanted was to add a flash movie that would start playing when the method is entered and will stop when the method finishes. Something like this:
The flash movie plays, but the speed is horrible, almoust frame by frame (it actually matches the stepping of the foreach method that fetches the mails from the server as i can see it retrieving one mail - the movie plays one frame and stops; retrieves another mail - the movie plays another frame and stops.).
In the loop that retrieves the messages, i added Application.DoEvents(); so that is not the problem.
Now i am thinking of somehow playing that flash movie on a separate thread that will not hang synchronous with the retrieving mails loop but i don't know how would i do that...
I want to create a simple map editor in winforms. I would like for it to use a tile sheet from the user which they then can click on tiles from it and place it on the specified grid. Then export this as a binary file. Or perhaps it would be easier for the user to chose the grid size then have each grid space's number be able to be changed like 01,02,03 to represent an image. Then export this as a binary.
