The size of the array is the same, because I am using the parallel array.

OleLoadPicture() is currently refusing to load a JPEG file created in Adobe Photoshop 7.0, it returns E_FAIL. From looking at documents on the format of JPEG files I have determined that the signature is not standard but the file is a JPEG of some variety. The correct signature does exist about 300 bytes into the file and if I ignore everything before the signature the image will load but the rendered results are not correct. The image will load in both Paint and the Windows XP image viewer so I'm happy the image itself is ok.
Does anybody have any suggestions as to why OleLoadPicture() fails?

Hi guys
I'm trying to understand how it works serialization in Doc/View architecture
I have a view with some controls associated to booleans.
When I do a Open File I want to read the booleans from the file and then update the view.
I've tried to Serialize in Doc and then Update in OnUpdate in View but the controls are not refreshed. What is the correct order to do these things?
I'm doing something wrong?
Best Regards

Do you have something like:
class CMyDoc : public CDocument
{
public:
bool bValue1;
bool bValue2;
};
void CMyDoc::Serialize(CArchive& ar)
{
if (ar.IsStoring())
{
ar << bValue1;
ar << bValue2;
}
else
{
ar >> bValue1;
ar >> bValue2;
}
}
void CMyView::OnUpdate( CView* pSender, LPARAM lHint, CObject* pHint )
{
CMyDoc *pDoc;
pDoc = GetDocument();
m_xbReady.SetCheck(true == pDoc->bValue1);
m_xbMixed.SetCheck(true == pDoc->bValue2);
}

Hi David
If I have to serialize a CArray variable how I have to implement in Serialize?

{
if (ar.IsStoring())
{
}
else
{
}
m_arr.Serialize(ar);
}

I am not sure the application, but let me try to give an example from what I've done.
First you must open the file where you serialized the data, here is a sample serialize code...
I would advice that if these are settings for the view and in no way have anything to do with the document data, then do not store the values in your document. Rather create a new file called ViewSettings.dat and save the values in that. Lets say ViewSettings.dat is in your c:\\Program Files\\Program folder. Where Program is your program In the sample below we will assume that bEnableWindow is the variable you wish to serialize.
in CView's OnInitialUpdate call the serialize function passing an archive of the file.. Here's how to do it.
void CView::OnInitialUpdate()
{
CView::OnInitialUpdate();
try
{
CFile fileViewSettings( _T("C:\\Program Files\\Program\\ViewSettings.dat"),
CFile::modeRead );
CArchive arViewSettings( &fileViewSettings, CArchive::load );
Serialize( arViewSettings );
}
catch (CFileException* e)
{
// if the file has not yet been created then initialize default values //
// and also create the file to where the values will be serialized.
e->Delete();
bShowVisible = TRUE;
CFile file( _T("C:\\Program Files\\EGames\\Settings\\FrameSettings.dat"), CFile::modeCreate);
// At this point we should either have set a default value for bShowVisible if the file
// had not yet been created, or if it had then we have successfully loaded it in.
myButton.EnableWindow( bEnableWindow );
}
void CView::Serialize( CArchive& ar )
{
if( ar.IsStoring() )
{
/* Save your variables
example:
ar << bEnableWindow ; Where bEnableWindow is the boolean
for enabling your control.
*/
}
else
{
/* Else load in your variable
example:
ar >> bEnableWindow ;
*/
}
}
I hope this gives you an idea! Questions?? my email is nateinstein@hotmail.com I've been doing doc view for the past year religiously and have 3 serialize functions for just one class lol.

Sorry accidentally forgot to edit a paste I made, in the mode create file the path should be..
Program Files\\Program\\ViewSettings.dat"), CFile::modeCreate

Serialization is evil. I'd recommend for simple stuff, just use a plain old text file or INI file. You can use CStdioFile to read in and write text files pretty easily.

Hi !
I have a constant which I want to use in many classes.
What I think I should do is put this constant in a header file, and include this header file in each cpp file of the classes which will be using this constant.
But, if I declare my constant like this :
const char* MY_STRING = "My string";
the linker complains that MY_STRING is already defined somewhere.
If I declare it that way :
const char MY_STRING[] = "My string";
Why is the first way not working ?
Thanks !

Have a look at the extern keyword.
_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do?? 
(doesn't work on NT)

How about just
#define MY_STRING _T("My string")
It annoys purists, but it works

I want to use accelerator keys in my modeless dialog, but PreTranslateMessage is not called. Anyone know how to solve this?
|
|
|
|
|
Interesting.
What keys did you map?

At the moment just Ctrl-F. But I don't see why that matters.
For some reason PreTranslateMessage is not called, so the TranslateAccelerator method is not called, with as result that non of my accelerator keys work.

I've seen this question asked here before, although I don't remember the answer. I suggest you do a Search for it.
Regards,
Alvaro
Can I ask you a question?
|
|
|
|

I found a similar post, but still don't know how to do this. I can't imagine I have to make a seperate message loop to handle accelerator keys, like the previous post suguests.

In the mdi project I could set cx and cy in the precreate function of the mainframe. But in the dialog based proj, how do I set the initial size of my dialog?
Thanks,

One solution is inside OnInitDialog().

Thanks. I used MoveWIndow because I couldnt decide what parameter 1 of SetWindowPos should be..
