Please see the function ::GetComboBoxInfo(..),
you can access the list in this way
and then move it at the new calculated position
(bottom -= GetItemHeight(..)*delCount) 
They sought it with thimbles, they sought it with care;
They pursued it with forks and hope;

I use VC6 , so I have not access to GetComboBoxInfo method ... but I try to retrieve rect drop down window information with GetDroppedControlRect(...) method ... I write you if I succeed it ! Thank you !
|
|
|
|

// I use VC6...
It should be possible :
void CYourDialog::Test()
{
CComboBox* pcBox = (CComboBox*) GetDlgItem(IDC_COMBO1);
if (pcBox->GetSafeHwnd()) {
pcBox->ShowDropDown(TRUE);
COMBOBOXINFO sCBINFO = {0};
sCBINFO.cbSize = sizeof(COMBOBOXINFO);
if (::GetComboBoxInfo(pcBox->GetSafeHwnd(), &sCBINFO)) {
if (sCBINFO.hwndList) {
CWnd* pcList = CWnd::GetFromHandle(sCBINFO.hwndList);
CRect cListRect;
pcList->GetWindowRect(cListRect);
cListRect.bottom -= 20;
pcList->MoveWindow(cListRect);
}
}
}
}
They sought it with thimbles, they sought it with care;
They pursued it with forks and hope;
They threatened its life with a railway-share;
They charmed it with smiles and soap.

I will try this , but tomorrow morning , and I will write you . Thank you !

I have tried it too,
you can call the function at any time :
void CYourDialog::AdjustComboBox(CComboBox* pcBox)
{
if (pcBox->GetSafeHwnd()) {
COMBOBOXINFO sCBINFO = {0};
sCBINFO.cbSize = sizeof(COMBOBOXINFO);
if (::GetComboBoxInfo(pcBox->GetSafeHwnd(), &sCBINFO)) {
if (sCBINFO.hwndList) {
CWnd* pcList = CWnd::FromHandle(sCBINFO.hwndList);
CRect cListRect;
pcList->GetWindowRect(cListRect);
cListRect.bottom = cListRect.top;
pcList->MoveWindow(cListRect);
}
}
}
}
They sought it with thimbles, they sought it with care;
They pursued it with forks and hope;
They threatened its life with a railway-share;
They charmed it with smiles and soap.

What are you saying? GetComboBoxInfo() has existed since Windows 98, about the same time that VS6 came out.

At my method list of CComboBox I have not this method : GetComboBoxInfo() ...

You're letting IntelliSense dictate what you (don't) have access to?

As GetComboBoxInfo requires windows 98 or above, make sure corresponding platform sdk is with you. I think February-2003 version is the last one that can be neatly compiled by VC6 compiler.
Also just ensure that the #define WINVER in your program meets the windows version for GetComboBoxInfo in winuser.h.

I have not installed any SDK ... this meen I can't solve the problem without SDK ? My VS6 is naked !

I want to make myself an AutoComplete combo box ... but I give up and use this[^] solution ... thank you all !

Dear all,
I have a console application that writes data to shared network drives. No problem if I launch it from command prompt or Windows explorer. But things go wrong if I call it from a Windows service created with sc command, The appliaction runs in memeory that is for sure, but for some reason it cannot get acess to network drives. ( both the console application and the windows service are wriiten in VC8 )
Please Help
Regards

Please, do not cross post. Yu have already got an answer here[^]

Thanks, But I need to know How to use my CreateProcess function from the service so that it can read or write any loaction on the system.
|

Hi,
The reason why you are able to access the drive in when you normally run the executable from command prompt is that when u are executing it as normal exe you are running that application in the User account from which you have logged on . And that user has the privileges to access the network. But , when you install the executable as a service , by default if you see in the task manage it runs under 'SYSTEM' account . And you might be knowing that the 'SYSTEM' doesn't have rights to access network resources.
There can be two solutions to this problem.
1. As Sauro Viti already pointed out in the link he gave you , to map the drive as persistent.
2. There is one more approach that can be followed. If you open the service manager by typing in the 'services.msc'you can go to your service and in the properties of your service there is a logOn tab where you can specify the account as any other account than 'System' you can either start service from your own logged on user account or through 'Network Service'. When you do this .. the service can access any network component and drive even if they are not persistent also.
To achieve this programmatically you can look into 'CreateService' function at
http://msdn.microsoft.com/en-us/library/ms682450(v=vs.85).aspx and can set the parameter 'lpServiceStartName ' to 'NT AUTHORITY\NetworkService'. This will start your service under 'Network Service' account and then you are done.
3. You can also try by making the service as interactive by specifying SERVICE_INTERACTIVE_PROCESS in the servicetype parameter flag of your CreateService() function but this will be limited only till XP as Vista and 7 donot support this feature.
Hope the solutions help you.. Let me know if this worked for you .

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 :
http://msdn.microsoft.com/en-us/library/aa379608(VS.85).aspx
This should solve your problem.

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

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->nCellIndex, pCellInfo->nSubCellIndex, &PhAnnContainer, CONTAINER_ACTION_ANNOTATION_RECTANGLE);
But still i am no tgetting any coordinate values.
Any idea will be helpful
Thanks
Raj

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).

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.

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.
