I am trying to create a OCX from a C++ dll., Here's the scenario I have a C++ dll and this dll needs to be called in VB.net program my boss want's me to create an OCX out of this.
C++ dll and use it in a VB.net class library, apparently I have created an OCX but it requires a form but the VB.net program is a class library.
I'm trying to create a simple webbrowser at my app.
code sample:
....
ATL::CAxWindow m_wndContainer;
ATL::CComPtr<IWebBrowser2> m_spWebBrowser;
HWND hWnd = m_wndContainer.Create(NULL,
CRect(0,0,200,100),
(LPCTSTR)0,
WS_CAPTION|WS_THICKFRAME|WS_OVERLAPPED|WS_MINIMIZEBOX|WS_MAXIMIZEBOX);
CoCreateInstance(CLSID_WebBrowser,NULL,CLSCTX_INPROC,IID_IWebBrowser2,(void**) &m_spWebBrowser);
...
everything is work fine except the fact the it seems that it create an IE version 7.0 and my machine have IE 8 installed.
it not suppose to create the IE according to my installed version?how do i suppose to do it?
How can I create a dialog as a DLL ? I have a SDI MFC app (CView is based on CFormView) and from a button I want to load a modal dialog, but that dialog must be developed as DLL ... I didn't find something that fit my needs on internet ... P.S. I have only VC6 !

View 3 Replies View Relatedhow to create, initialize, and maintain a memory device context that works as a local buffer for images? The idea is to maintain some large images in local DCs and bitmaps, and only bitblt them to screen in OnDraw().
What I did so far was was to define CDC and CBitmap objects as members of my View class, and then tried to initialize them with the sequence that begins at "// Initialize buffer". I placed that sequence in either OnInitialUpdate, or PreCreateWindow, or OnPrepareDC, or the view constructor, to no avail. The code always crashes in OnDraw, and I've noticed that the m_hDC member of myDevice is zero at that point.
Obviously, the initialization is wrong and MFC does (too many) things in the background which I'm not aware of.... My question was where can I read about that?
Code:
class CMyView : public CScrollView {
// ...
CDC myDevice;
CBitmap bmp;
CBitmap *oldbmp;

How can I create MS Word 'print layout' like interface. The attached picture says it all. Basically I want a shaded area around my document just like word so it gives a feel of the 'page'.
I was hoping I can override some function somewhere and along that lines tried playing around with below but that didn't work.
Code:
BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs) {
if( !CFrameWndEx::PreCreateWindow(cs) )
return FALSE;
// TODO: Modify the Window class or styles here by modifying
// the CREATESTRUCT cs
cs.cx = 250; // just playing around with size
cs.cy = 250;
return TRUE;
}
How can I do that?

View 1 Replies View RelatedHow can I implement the paradigm demonstrated by the code below to run on WinXP?
I want to fork a process or create a thread that shares global variables with the parent process/thread.
The child process/thread monitors the progress of the parent process/thread.
I cannot find documentation for a fork function per se, a Unix term. It might be called something different for WinXP.
I would be happy to use threads instead. But I'm rusty even with Unix application threads; and I know nothing of WinXP application threads.
So any turnkey implementation that demonstrates the simplest use of process or thread functions for my purpose demonstrated below.
In either case, do "forked" processes and threads share global address space in WinXP, as they do in Unix?
I would prefer to avoid the overhead of IPC mechanisms. The "overhead" includes my own relearning curve.
The GUI screwed up my indentation. I would try to correct it. But the proper indentation appears when I edit the posting. I suppose I need to insert real tabs. Haven't figured out how (yet).
Not even real tabs work; and I cannot get the "paste as text" button to behave as I expect. What is the trick for posting indented text in this GUI?

View 1 Replies View RelatedI am wokring on a project that has used an MFC DLL in conjunction with Outlook to send and archive mail. I need to be able to create folders for integration from an older mail system. I have looked online to see if there are examples in C++ (since I have to modify the existing C++ dll to include the funcitonality). I realize it is much simpler using VBA or C#, but I am limited with my choice. I essentially want to use the MFC type lib for Outlook 14 and use the CMAPIFolder,CFolders create folders in the Inbox.

I'm trying to create an edit box in a CView.So far, this is how far I've gotten:
With this code
Code:
// .h
CEdit m_MyEditField;
// .c
m_MyEditField.Create(WS_CHILD | WS_VISIBLE,CRect(40,40,500,Y+55),this,0x1552);
m_MyEditField.SetWindowText("this is my CEdit field");
As you can see, the edit box doesn't look like the ones in a dialog, which is what I'm trying to accomplish.
Is there possibly some other class I should be using for the edit box?Or another setting for .Create?

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.
What I observed in the OCCSITE.cpp:
Code:
_AFX_THREAD_STATE* pState = AfxGetThreadState();
if (!pState->m_bNeedTerm && !AfxOleInit())
return hr;
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...

Does it support 6.0 version?
An ImageList_Create() function (see here) takes 2 parameters: cx and cy which are the width and height of each image.
Everything is good if I know in advance what size my images will have. But what if I don't?
Let's say I select 32x32 and my images are sized as 16x16. What will happen with the image list? Or my images are 48x48 and the image list should grow to accomodate the extra space. Since on Windows image list is just one big bitmap, will the height of the image list shrink/grow to 16/48 or not? Is there a way to test such behavior?
The problem I'm having is to check whether the actual images will be truncated when they are bigger that the image list initial size or not or whether I will see some extra space if the images are smaller.
The closest way I see is this function, but I am not sure its the right one to apply to the image list itself and not to the image inside the list.

I am reading from a text file and want to create a program that will perform the same calculation for every oscillation.
The text file I'm reading from is attached to this post. A3.txt
The program that I've written is as follows:
Code:
#include <iostream>
#include <fstream>
using namespace std;
int main() {
ifstream inFile ("AP1.txt");
ofstream results_file ("APDuration.txt");
[Code]...
Where I'm having trouble is in having the inFile.seekg function iterate to the next series of values.
Here is what the data file looks like in a graph:
In a nutshell, my program will read the duration of each action potential from a point called "dVmax" (where the upstroke is at its maximum upward rate of change) to the point of 90% repolarization (on the downstroke where 90% of the total wave amplitude is subtracted from the volts at peak amplitude).
If you would like to test my program on one action potential, here is one action potential : AP1.txt

My setup is as follows:
There is function written C++, that must be compiled to DLL. This DLL is linked to some CAD (computer aded design) tool, that has special interface for it.
I want to add to this function some GUI (graphical user interface). So the creation of a window is necessary.
I've tried already with Win32, but without success.
The problem is that CreateWindow function requires application instance handle, that is provided by Windows itself when window is created in "normal conditions".
What I want to do is create a file that will ask the user to enter his info,n then store it in a text file The screen will ask the user if he wants to update his info. if he says yes then the screen will be cleared and the old info will be printed on the screen. The user will enter his new info that will be stored in a new file. My problem is that once the user finishes entering his input the program just closes D: and the rest of the program won't run.
Code:
int main()
{
string ans;
ofstream Xfile("original.txt");
cout <<"Enter your name and address please"<<endl;
cout<<"Press Ctrl+Z+Enter when you are done"<<endl;
string name_and_street;

I have a problem with creating a process and waiting until the main window of the new process was shown. I thought I can wait for it with
WaitForInputIdle(pi.hp,INFINITE);
But when the function returns, the handle of the main window of the new process is not available. If I include also a ::Sleep(), the new window is available. Sleep is a bad solution. How can I do it?
