I am writing 2 activex controls. I wanted to pass a function pointer between them. Is this possible? Any clues how??

It's not possible.
You could aggregate the function in some interface and then pass the interface pointer between the controls.

I have an 8bit DIB as a bitmap resource.
The problem is that I can't paint the bitmap properly in 256 color mode. When the bitmap is displayed its colors look strange.
I use LoadBitmap to get the handle to the bitmap and then I blit it to the screen from memory context.
Is there any quick way to solve this problem ? How do I get the palette from the bitmap resource ?

Use LoadImage with LR_CREATEDIBSECTION so that your bitmap
is loaded as a DIB.
Then use GetDIBColorTable to get the bitmap's colors and
CreatePalette to make a palette from them.
Use SelectPalette to select your palette into the DC, and
then RealizePalette to get your colors into the system
palette.
Your bitmap should then look ok.

Hello.
For a c++ Prog. i get CTime-Object from a access-DB.
Converting into a Time-String for a Edit-Field is not
a Problem. But:
I have for Input three Date-Time-Picker, one for the day,
the month, and the year.
I've a great Problem to show the corrct dates in the
Date-Time-Picker.
First i'have tryed with a member on the dtp to convert
the format member.setformat("dd"). This was ok. The
DTP caught the systemtime korrekt in the form.
But now I want to initialisize these tree DTP's with
the Access CTime-Object. I'have tryed to split the
CTime-Object with Format %d,%m,%Y)an then with setwindow
text as Cstring. day and month was ok, but not the year
(1970, instead of 1980), by the same method.
Otherwise by storing i must store these three objects
(day,mon, year) into a CTime-Object.
Has someone a good idea for handling this?????????
Thanks....

Here is my problem
I want to check a specific folder in FTP for the checking of arrival of new file in a specific interval of time..i think i can do that by comparing the latest date/time of the file..how can i get the date/time of the file(or such file related info other than filename) created in a FTPfolder,i think there is no such member functions for CFTPConnection or CFTPFileFind..
help wanted..!!!

Haven't tried it, but perhaps this works:
CFTPConnection->OpenFile
CInternetFile(derived from CFile)->GetStatus
In the CFileStatus retrieved you have creation/modification times.

How to embed information data and retrieve it from other applications?
I have a proprietary data file format that contains graphical data. I would like to embed customer and job related data and be able to extract the data to display in other applications (i.e. Excel).
I would assume I could place the data in my file format anyway I want. But how does Excel or other application extract this data. Do I write a DLL with functions to extract the fields of information?
I’m open to any ideas but I’m limited to VC++ 6.0 (no .NET, C#)
Many thanks in advance

Just curious but does it have to be embedded? Because you could create an external comma delimited file or even an HTML file and use Excel, etc. easily. I found that comma delimited and HTML are more universal than a propietary data format.

|

|

Yes, you can do it. To be specific it should be ATL COM Dll which implemenets IDExtensibilty2 interface.
This COM dll will be loaded when excel comes up. When user chooses to open the selected file, a notification will be fired by excel application to all the listners of IAppEvents. At this stage, component should read from file and stuff it in Excel columns.
Check out more for COM add-in dlls in Office applications.

I want the data embedded because the file gets move around alot by the user, backups, floppy, etc. Learning from the past it's better to keep the data all together. I will agree csv and the like are easy to use.
Thanks for your thoughts

I've posted a question to this board before asking for help with getting a variable from a Dialog to be displayed in the current document. The only replies I got were on how to get the variable out of the Dialog (thank you very much for those, they helped), but not how to display it in the current document.
Can anyone help me? I can't find a tutorial on this, HELP!!! I know it has to be something easy, but I can't find it. I'm using and MFC MDI with Doc/View Arch. I need this in order to get some homework done for a class. Please, is there anyone who can walk me thru doing this?

What voew class did you use as the base class for your view? If it is a CFormView then you can actually add controls via the resource editor! And then use these controls to display data.
If it is a bare CView derived class you can either create these controls manually or you can use one of the text outputting functions to draw the text on the view. But I am not sure whether that's such a good idea.

Right now I would be happy just to get the data into the document so it can be saved into a file and then printed. I can get everything else to pretty much work, except getting the document to display. Why is this simple task so darn frustrating?!?!?!?
So how do you use the form view? I had intended to use editview for annotation and perhaps color, but I think Rich edit is what I need for that. Any suggestions?...besides throwing the computer out the nearest window...

Refer to Kb article http://support.microsoft.com/default.aspx?scid=kb;EN-US;q108587 to fetch the document or view class from anywhere in the MFC app.
Once you have the document pointer, store the (dialog) data in member variable of document class.
void CMyDialog::OnOK()
{
UpdateData(TRUE);
CMyAppDoc * pDoc;
pDoc = (((CMDIFrameWnd*)(AfxGetApp()->m_pMainWnd))->MDIGetActive())->GetActiveDocument();
pDoc->m_Data = m_szDialogdata;
pDoc->UpdateAllViews(NULL);
}
- UpdateAllViews inturn will call OnUpdate function internally. So, implement all the view presentation data on OnUpdate().
void CMyAppView::OnUpdate()
{
//load document using memeber variables
//if using formview, call
UpdateData(FALSE);
}

There is no point calling the base method as far as I can see. You're about to undo what it does anyhow.

How do you change the background color of a CListBox. There isn't a SetBkColor and I tried the CDC::SetBkColor unsuccessfully. I may have done it wrong but this is where I am stuck. Thank you for your help in advance.
