I am using PowerPoint automation to display PowerPoint file from my project. But sometimes the PowerPoint file is displaying behind my main application. How can I get the handle of the PowerPoint window from my project?
|
|
|
|

You can keep your application behind the ppt by using
this->SetWindowPos(&this->wndBottom,,,,,)
Also to get your ppt window, you can use FindWindow("WindowName",NULL);

_Application app;
app.CreateDispatch( "PowerPoint.Application" );
.........
SlideShowSettings m_pptSlideShowSettings;
.........
// Run the slide
m_pptSlideShowSettings.Run();
How can I get the handle of the running slide window?
What will be the "WindowName" name in the function FindWindow("WindowName",NULL);

Sorry for the typo that's the classname of the applicaiton. If you want to catch using the name displayed on the title bar, you should past it as the second argument.
Open a notepad, minimize it. Then run the below code:
HWND h = FindWindow(NULL,"Notepad");
ShowWindow(h,SW_MAXIMIZE);

Hello,
I have a project without document-view architecture. I added a (TableF)childframe derived from CMDIChildWnd and a (HeadView) childview derived from CView which is a member of childframe. When I execute, the childframe that is the window is been made properly with the view but the window gives debug assertion error while closing.
class TableF : public CMDIChildWnd
{
DECLARE_DYNCREATE(TableF)
protected:
TableF();
protected:
virtual BOOL PreCreateWindow(CREATESTRUCT& cs);
protected:
virtual ~TableF();
HeadView Heading ;
afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);
DECLARE_MESSAGE_MAP()
};
class HeadView : public CView
{
//protected:
public:
HeadView(); // protected constructor used by dynamic creation
DECLARE_DYNCREATE(HeadView)
public:
//Operations
public:
virtual void OnInitialUpdate();
//protected:
public :
virtual void OnDraw(CDC* pDC); // overridden to draw this view
public :
virtual ~HeadView();
#ifdef _DEBUG
virtual void AssertValid() const;
virtual void Dump(CDumpContext& dc) const;
#endif
}
The above are the view and frame classes.

Usually the error messages are quite informative: you should probably post the whole error message. Moreover it is a good idea to mark for us, in your code, the asserting line.
You should properly post code snippets using the code block button.

Hello,
I have a project without document-view architecture. And I wanted to ask if ChildView member of the Childframe can be derived from CView.I am deriving a childview from CView and this childview is a member of childframe . When I execute the window is opened but while closing I am getting the above error.
Thanks for your reply

I have an MDI app with a docking property pane using CMFCPropertyGridCtrl. The property pane is updated with document and multiple modeless dialog property data using OnSetFocus() to populate the appropriate data depending on which document or dialog has the focus.
The problem is if I have the focus on a dialog with a document also open and want to change a property by selecting the property pane the focus is changed to the document first thus changing the property pane data to the document data.
Basically what is happening is whenever the main frame (i.e. docking pane) is selected the last document view also receives the focus (first). Is there any way to prevent the document view from receiving the focus when the docking property pane is selected?
Thanks
JC

WAVEFORMATEX structure is said to replace the old WAVEFORMAT structure. With WAVEFORMATEX for waveInOpen, the Subchunk1Size is set as 18 somewhere by the API ( ? ). And it is treated as non-PCM when Subchunk1Size is not 16. How to set the value of Subchunk1Size to 16 when I am creating a wav file? Thanks.
Reference: WAVE PCM soundfile format [^]

I have a very basic MFC Dialog Program and a Stack ADT.... My Question is where can i declare an instance of the Stack ADT in the GUI Program so that i can manipulate the members inside with the button clicks....
Thanks in Advance...
|
|

GUI Programming is not for the aliens. They still have classes & objects. Your STACK-ADT is just another class. So your dialog class is just going to "use" that class or "contain" an object of that class.
<br />
1.Open up the solution explorer, <br />
<br />
2.Select the headers folder, <br />
<br />
3.right click, add-existing-items, add your "Stack-ADT" header, <br />
the same way for the cpp files into the "source" folder.<br />
<br />
4.Include "stac-adt.h" in to your Dialog class (Your "GUI").<br />
<br />
5.Now everything's ready for use. <br />
<br />
6.You may create the stack object inside your dialog class, <br />
may be it a member or a temp object inside a function. <br />
<br />

my project is about DSL download organiser to limit the download and upload of a pc connected throught a server to the internet, i use the c++ code, and buffers to save data as bytes in it and test if the size < limit or = but i dont know how i can know if a pc download or upload, and how i can copy the data (downloaded) from the internet explorer to the buffer, to test if the size is ok or not.
so what is the function to know if the pc use the internet to download or upload.
what is the function to add the data downloaded to the buffer as bytes.
10x
the code:
if(download) ??????????
{
void downloadlimit( )
{ AnsiString IP;
For(int i=0; i<nbofpc;i++)>
Switch (IP)
{Case ‘10.15.1.157’: buffer[limitbypc] = fputs(data); ?????? how i can copy the data as bytes to the buffer
(If(sizeof(data)) == sizeof(buffer)
WriteString (“you can’t download more”); break;
Case ’10.15.1.158’: buffer[limitbypc] = fputs(data); break;?????????
If(sizeof(data)) == sizeof(buffer)
WriteString (“you can’t download more”); break;
……………
Case’10.15.1.164’: ……….; break;
}
}
Return 0;}}
if(upload) ??????????
{
void uploadlimit( )
{ AnsiString IP;
For(int i=0; i<nbofpc;>Switch (IP)
{Case ‘10.15.1.157’: buffer[limitbypc] = fputs(data); If(sizeof(data)) == sizeof(buffer)
WriteString (“you can’t upload more”); break;
Case ’10.15.1.158’: buffer[limitbypc] = fputs(data); break;?????????

You need to hook the gateway and watch out for the incoming & outgoing packets, extract their IPs & make thing accordingly. I'm not sure about other ways of doing it, But I'm little surprised at people throwing requirements like these to freshers.

I am trying to use radio buttons in Studio 2008 and I don't find it as easy as it used to be in VC++ 6.0 or maybe even in Studio 2005.
Here is what I have. I have a group box that contains three sets of radio buttons.
Set 1: (altitude) meters or feet
Set 2: mach or velocity
Set 3: (if velocity, units) ft/sec, m/sec, mph, knots
I layed this out by creating a label for each set and then putting down the buttons for the current set I was building.
Static label 1: Altitude is: (then I put two radio buttons - meters, feet)
Static label 2: Specify: (then I put two radio buttons - mach, velocity)
Static label 3: Units for velocity: (then I put down 4 radio buttons....)
When I click a button in Set 1, i want it to update a variable - m_nAltitudeFormat.
When I click a button in Set 2, i want it to update a variable - m_nMachOrVelFormat.
When I click a button in Set 3, i want it to update a variable - m_nVelOptFormat.
Studio2008 doesn't do the simple things (??) that previous versions of Studio used to like create the message mapping.... help! (when i tried cut/paste old method, got into more trouble.)
Thanks,
John John
