Hi Kushagra,

Thanks a lot for your help. I will just try with the methods you described.
I have also came accros some posts where it is said to use CreateProcessAsUser function to launch the child process. But I could find a proper code to get the "Token Handle" to be used as a parameter to this function. Could you please help me in this area. ?

with thanks and regards

For doing this .. First you will have to make the service as 'INTERACTIVE' as I mentioned in the earlier reply. Then if u are using the function CreateProcessAsUser() you will have to fallow the process as mentioned in this link :

This should solve your problem.

How to get the co-ordinates of rectangle

Hi all,
I dnt know whether its a right forum for this question.If any one can help me it will be helpful to me.

I am drawing a rectangle using LeadTools.

Here is the code :

void CImageViewerView::OnAnnotationRectanle()
{
  m_ImageViewer.SetAction(CONTAINER_ACTION_ANNOTATION_RECTANGLE,CONTAINER_MOUSE_BUTTON_LEFT,FALSE);
m_ImageViewer.EnableActionCallBack(TRUE);
	   m_ImageViewer.SetAction(110, CONTAINER_MOUSE_BUTTON_RIGHT, DCACTION_ACTIVEONLY);
}

How can i get the co-ordinates
1) m_ImageViewer.SetAction : Sets the rectangle for left mouse button.
2)m_ImageViewer.EnableActionCallBack: Returns if the rectangle is drawn.
3)I want to use GetAnnotationContainer() for returning the co-ordinates.

m_ImageViewer.SetAction(110, CONTAINER_MOUSE_BUTTON_RIGHT, DCACTION_ACTIVEONLY);

This is working fine for me,I am changing the rectangle action to Right Mouse button

Here is the API :
   L_INT GetAnnotationContainer(L_INT nCellIndex,L_INT nSubCellIndex,HANNOBJECT * PhAnnContainer,L_UINT uFlags);

I have this in .h file

typedef struct tagDISPCONTAINERCELLINFO
{
   L_UINT uStructSize;
   L_HDC  hDC;
   L_INT  nCellIndex;
   L_INT  nSubCellIndex;
   RECT   rcRect;
   RECT   rcBitmapRect;
   L_INT  nX;
   L_INT  nY;
}
DISPCONTAINERCELLINFO, * pDISPCONTAINERCELLINFO;

When i am trying to use the same

pDISPCONTAINERCELLINFO pCellInfo;

void CImageViewerView::OnAnnotationRectanle()
{
  m_ImageViewer.SetAction(CONTAINER_ACTION_ANNOTATION_RECTANGLE,CONTAINER_MOUSE_BUTTON_LEFT,FALSE);
m_ImageViewer.EnableActionCallBack(TRUE);
	   m_ImageViewer.SetAction(110, CONTAINER_MOUSE_BUTTON_RIGHT, DCACTION_ACTIVEONLY);
 m_ImageViewer.GetAnnotationContainer(pCellInfo->nCellIndex, pCellInfo->nSubCellIndex, &PhAnnContainer, CONTAINER_ACTION_ANNOTATION_RECTANGLE);
}

But i am getting memory cannot read for pCellInfo->nCellIndex (Run Time error)

If any one knows what i am doing wrong,please help me

Thanks
raj

You're accessing memory through an uninitialised pointer (pDISPCONTAINERCELLINFO pCellInfo;). In this situation the behaviour you're getting is exactly what's expected.

Hi,
I corrected with

DISPCONTAINERCELLINFO pCellInfo;
m_ImageViewer.GetAnnotationContainer(pCellInfo-&gt;nCellIndex, pCellInfo-&gt;nSubCellIndex, &amp;PhAnnContainer, CONTAINER_ACTION_ANNOTATION_RECTANGLE);

But still i am no tgetting any coordinate values.
Any idea will be helpful

Thanks

Here's the API you gave in an earlier post:

Here is the API :
   L_INT GetAnnotationContainer(L_INT nCellIndex,L_INT nSubCellIndex,HANNOBJECT * PhAnnContainer,L_UINT uFlags);

I have this in .h file

typedef struct tagDISPCONTAINERCELLINFO
{
   L_UINT uStructSize;
   L_HDC  hDC;
   L_INT  nCellIndex;
   L_INT  nSubCellIndex;
   RECT   rcRect;
   RECT   rcBitmapRect;
   L_INT  nX;
   L_INT  nY;
}
DISPCONTAINERCELLINFO, * pDISPCONTAINERCELLINFO;

And here's the updated code you just posted (I've corrected the incorrect escaping):

DISPCONTAINERCELLINFO pCellInfo;
m_ImageViewer.GetAnnotationContainer(pCellInfo->nCellIndex, pCellInfo->nSubCellIndex, &PhAnnContainer, CONTAINER_ACTION_ANNOTATION_RECTANGLE);

The pCellInfo variable is still not inititalised! In fact this code is worse, it will not even compile: pCellInfo is not a pointer (despite it's name suggesting it is) but is used as if it is (pCellInfo->nCellIndex).

Outlook bar with variable number of controls fails to draw

old_hacker28-Sep-10 17:48

28-Sep-10 17:48

Using a COutlookBar, and adding a different set of controls each time the app runs, depending on user's access rights. Somewhere in the bowels of the MFC class is code that saves the window state in the registry and retrieves it when you run the app again, so as to reposition the docked panes etc. as the user left them. This works OK if the set of controls added to the outlook bar is the same as the last time the app was run; however, if not, the code seems to screw up the calculation of the window size or position, with the result that it fails to show the outlook bar at all.

Is there a recommended way to add/remove controls from the outlook bar, to achieve what I need? Hiding the controls works as far as displaying the bar is concerned, but it also means that the user can enable them again from the 'Navigation Pane Options' button, so that's not an option.

How to get control of another code's dialog box

I'm not sure this is possible - is there a way that I can do the following - I'd like to modify the text in the the filename Edit box of a File Save dialog in a 3rd party program (for which I don't have the source code). Could I do this by using Spy++ to get the handle to the dialog and the Edit box, then use my code to modify the text?

Thanks!

Tom

Yes, I think it is called automation. It takes figuring the dialog's handle, the textbox's handle (or its tab position), then sending some characters using SendKeys. I tend to identify the foreground window (using user32's GetForegroundWindow) to improve the reliability.

Warning: whatever you do it won't be fool proof (unless you can use an API the app provides). There always is a possibility something unexpected happens, e.g. another dialog pops up informing the user about an exceptional situation; and the interactive user might be interfering too.

[ADDED]
Automation may also stop working when the system load changes dramatically (so operations suddenly exceed the timeouts you have installed), when the app's settings (or the system's regional settings) get changed, when a new version of the app gets installed.

How to make the release version of a visual studio 2008 c++ project so i can step in and debug?

the trouble i am having is the debug works fine but the release crashes.
so i want to step into the release version....
it could be done in vc6...how to do it in vs2008?

You can debug a release version but the code tends to have been moved around a bit by the compiler. Make sure you're building with debug information (right click on project->settings, C++->general, debug information format set to program database) and then copy the PDB file to the directory you're running your code from. If it doesn't remove the bug try disabling optimisation as well - it makes debugging easier.

Cheers,

Ash

thank you Ash!

I did what you said...

Make sure you're building with debug information (right click on project->settings, C++->general, debug information format set to program database)

then I set a breakpoint in the release version of the code (in the IDE) and ran it expecting it to stop at the breakpoint. But it did not and the breakpoint did not look colored anymore. It just ran on and crashed.

I would like the code to stop executing at the breakpoint so I can step in and proceed line by line.

thanks!

Generally, you go to the trouble of debugging a release version because the debug version is working and you want to see why optimizations are screwing up the release version. If you turn off optimizations, you have the debug version.

Hi!
I've declared a protected variable in a base class. I've assigned value and print the variable in a derived class. It prints correctly. I've printed the same variable inside another derived class. But it prints nothing. How to print the variable that is altered inside another derived class?
