if it is a standard ct terminal:

search for the ct-api
(Card-terminal Application Programming Interface)

or you can search for a documentation
of the ctrsct32.dll

or you search for ct-bcs
Card Terminal Basic Command Set

i got one here, but it is in german OMG | :OMG:

Debug with .NET 2003

Hi !

I just started developping with Visual .Net in C++ (unmanaged).

I'm facing a strange behavior in the debugger : if I go step by step in my code (F10), the debugger just step over many lines of code, and the variables viewer let me see that the object I'm debugging is in a very strange state, many member variables being uninitialised (which was supposed to be done in my constructor).

Did you already had such a strange behavior ? Is it possible to solve it ?

Thanks !
Jerome

Is this an existing piece of code converted from VC6 to VC7 or is it new code?

If existing code, try a complete clean of the DEBUG directory and compile again.

How to reposition Modeless Dialog box on resizing application window

Hai all,

I use a modeless dialog box in my application.

when I resize the application window, I can not change the position of the modeless dialog box, correspondingly.

How can i prevent it?
Also, the window for the modeless dialog in the task bar is also seen.

Simply, I am trying to make the Modeless Dialog box to be a part of my application window.

Please help me,

With Thanks and Rgds,
Arun

If my understanding of your problem is correct, you are trying to use a modeless dialog to look as if its a "pane" within your application. If this is correct, read on:

1. Make the dialog a CHILD dialog
2. In the parent window, handle the WM_SIZE message and then merely resize the child dialog.

For example (a WTL eg):

<br />
void OnSize(UINT uiCode, CSize sz)<br />
{<br />
  CRect rect;<br />
<br />
  GetClientRect(&rect);<br />
  if ( ::IsWindow(m_MyChildDialog.m_hWnd) )<br />
  {<br />
    // do some manipulation on the rect if needed...<br />
    rect.DeflateRect(10,10,10,10); // here I'm just decreasing the overall size of the rect<br />
    m_MyChildDialog.MoveWindow(&rect);<br />
  }<br />
}<br />

That should be all you need to do.
Let me know if I've missed your question completely.

Cheers,
Peter

How To read an exe application from VC++6.0

Hi,

I know how to run a VB exe file from VC++6.0 but have been trying to read the contents of the exe from VC++. Like if the VB application has ODBC coding in it then I would like to read the kind of API calls that it is making through VC++ application. Is it possible to do like that?. Is it possible to intercept an exe program and know what all objects it is accessing? If yes then how do I do that?

Thanks in advance.

I think what you are looking for is an "API hook." There are several examples here at CP. You can also Google for more.

Another way would be to parse the EXE itself by examining the .idata section (i.e., import table) of the file. It lists the functions called in other DLLs.

Detecting Mouse Movements Across an IE Control

27-Jun-04 22:30

I'm using MFC to host IWebBrowser2 in a child window (as a CWebBrowser2 control). I want the parent window to be informed whenever a WM_MOUSEMOVE message occurs on the child.

I can't figure out how to do this. I'm hoping someone smarter here can help me.

Basically, when hosting IE in a control (and I'm using MFC), how can my parent window be notified if the mouse moves across the control???

Thank you very much for your help!

You can use the DOM events to do that. You can hookup the HTML window or the document objects mouse move event.

The easiest way i can think of using MFC is to watch for WM_MOUSEMOVE in the parent window's PreTranslateMessage() function. You won't get any information on what HTML element the mouse is over though, so if you need that then do it Rama's way.

Tab Order suddenly began going backwards

ohadp27-Jun-04 22:23

27-Jun-04 22:23

I have an application with several dialogs, all have logical Tab-Ordering.

Everything was great up until a month ago when suddenly, the tab order began changing. Some dialogs presented a reverse tab-order and some a very puzzling tab-order.

I've checked my resources with the built-in resource-editor in VC, checked the .rc file, used an external viewer and the order looks like it's suppose to look, but my application decides to twist it.

What could cause this sort of behaviour ?
Where should I look for the causes of this problem ?

Is it possible that the dynamic creation of controls can cause this kind of behaviour ?
How are dynamically created controls treated with tab-ordering (I'm asking although my dynamic-controls do not have the WS_TABSTOP style) ?

thanks

Please re-write your question. I am not going to write a 50 page report on how to use 1394 on windows. I think I'd know the correct answer if I knew what question you needed answered.

There is a big different between having something that works on USB that you need to make work with 1394, and a new program you are writing from scratch.
