Can somebody provide me some links or code which will read a JPEG,GIF and display it in a window .Iam doing a MFC project 
|
|

did you try searching this site? (maybe in the Bitmap and Palettes section?)
there are like a dozen articles that show you how to do this.

You can display JPEG, GIF with the help of List Control (CListCtrl). One method "SetBkImage()" of CListCtrl class allowed JPEG,GIF images to display.

Take a look at CxImage. It's a great image processing library with support for TONS of different image formats.

Good Luck!

If you are using MFC 7, you can use the new CImage class.

1) Create a SDI application deriving you view from CHtmlView and display a HTML page with an image format of anything you want.
or
2) Embed a webbrowser control in a dialog application and do the same thing.
or
3) If you are using MFC 7 you can derive you dialog from CDHtmlDialog and display the html page.

why does my Autocompletion don't work. I'm my Constructor it does work, but wenn i make a function it doesn't work anymore.
the program compiles without errors
|
|

|
|
There are probably several reasons why it doesn't work consistently. I venture to say that most experienced C++ developers have accepted that it doesn't work all the time, and we simply don't rely on it.
The most common cause for it not working is when there's a syntax error higher in the source code.

I am Playing Enhanced MetaFIles around the Rectanges,Ellipses .. etc with rotation.But taking lot of time for play around the objects.How to imporve the speed?I don't show the end user to How I am playing?
((IMP: Actually I am loading files are derived from eps.
ie means I was opened eps files in corel draw the saved as Emf file.
But If run emf file derived from corel draw(directtly) no prob))
I wrote following code for ellipse
ENHMETAHEADER *pEnhHeaderData;
pEnhHeaderData = (ENHMETAHEADER *) meta_data;
hemf = ::SetEnhMetaFileBits( pEnhHeaderData->nBytes, (unsigned char*) meta_data );
GetEnhMetaFileHeader(hemf, sizeof(emh), &emh);
int x_radius=w/2;
int y_radius=h/2;
for(int i=0;i<360;i+=30)
{
//First File
hdcEMF = CreateEnhMetaFile (NULL, NULL, NULL, NULL) ;
angle=360-i;
EnumEnhMetaFile (hdcEMF, hemf,EnhMetaFileProc, NULL,(RECT *)&emh.rclBounds) ;
h1 = CloseEnhMetaFile (hdcEMF) ;
double a1=(i*3.14)/180;
int x_point1 = rect.left + center.x + cos(a1) * x_radius;
int y_point1 = rect.top + center.y + sin(a1) * y_radius;
SetRect(&rect1,x_point1-ezpn_frame_edge,y_point1-n_frame_edge,x_point1+ezpn_frame_edge,y_point1+ezpn_frame_edge);
pDC->PlayMetaFile(h1,&rect1);

Hi all,
I have a SDI applicaction that shows a modeless dialog box to inform the user about the progress of certain calculation.
I do the following:
CWnd* pWnd;
....
pWnd = GetDlgItem(IDC_EDIT1);
pWnd->SetWindowText(_T("Calculating...."));
I get an assertion error in the SetWindowText line.
Any ideas?
I'd appreciate any help.
Thanks.

You should check before if your IDC_EDIT1 has been created. If there is no window, you can't send it a message to update its window text;)
In short, you can not set the text in the constructor. Set in in OnInitDialog()
My opinions may have changed, but not the fact that I am right.
|
|
|
|
|
But I can't set it in OnInitDialog, becuase it is a text that I wnat to change constantly, informing the user about what the applicaction is doing!

Then create a function like UpdateText(const char* text) in your dialog class and call it from your main app like that: pWnd->UpdateText("foo");. Make sure to check in your UpdateText function, whether the handle to the Edit control is valid.

Then you simply have to make sure that your edit-control is created before you call SetWindowText().
My opinions may have changed, but not the fact that I am right.
|
|
|
|
|
|
pWnd = GetDlgItem(IDC_EDIT1);
if(::IsWindow(pWnd->GetSafeHWND()))
pWnd->SetWindowText("text");
This should work.
But I suggest you creating a function in a dialog that will do this thing for you, read my post above.

Okay, with this code I don't get the error, but I never get the text either, because it seems that it's never a window. Why? I have created the modeless dialog with Create:
BOOL bCreaDialog=pDialog->Create(IDD_DIALOG2,this);
I have tried with the function in the dialog code, but I have the same problem. No change. It seems that the control does not exist????????
ANy ideas, pleazzze!
|
|
|
|
|
Have a IsInitialized() function in your dialog-class, returning a bool. That bool variable is set to false in the constructor, to true at the end of OnInitDialog().
Now, before you call SetWindowText() you check that IsInitialized() is true.
Better still, you use the 'Gregor S method'.
My opinions may have changed, but not the fact that I am right.

Using MSDEV6 I run a tool, redirecting the tools standard output to the MSDEV output pane. I find this output pane is limited in the number of lines (a few thousand, as it seems).
Does anyone know what the limit is, and more to the point does anyone know how to increase the number of lines the output pane can hold?
TIA
Bernd

Hi,
I have to pass a BSTR string which is read from a xml file(using simple C-style fopen,fgetws methods) to a COM method. Within the COM method this BSTR string is to be passed further to a method that takes _bstr_t as a parameter. The problem arises when the BSTR string is to be passed further to the method contained within the COM method. The conversion from BSTR to _bstr_t converts only a portion of the string and not the complete string.
Since _bstr_t is just a wrapper over BSTR, it must take BSTR and form a object of _bstr_t,but the object is not showing the complete string passed to it. How do I solve this problem??
Thanks and Regards,
Abhishek.

Try using the BSTR in the _bstr_t's constructor, e.g. _bstr_t stuff(/*BSTR here*/);
This should solve your problem

ASSERT_VALID(pd);
m_add.GetAddress(m_ipsource ) ;
pd->ipad=m_ipsource;
class2 c2;
CDialog::OnOK();
