Actually i want to dev. Activex control or one of my Visual Basic project

You mean print to the printer ? If your mapping mode is MM_TEXT, you'll find everything is stupidly small, because an A4 page can have 4000x6000 'pixels' and so you get a postage stamp in the corner from your code created for 800 x 600. I set up a flag to make the code in OnPrepareDC/OnDraw/OnPaint not execute at all, because what I'm working on, I want a different result when I print ( a report ) anyhow. I do all my printing in OnPrint. If you *do* want the printing to be the same, the trick is to draw things relative to the DC size, which you get from GetDeviceCaps(dc, HORZRES) and VERTRES. Either way this is how I do my OnPRint, because I don't know ahead of time the DPI of the printer my users will be using. If you do this and draw with stretch blt, you'll be able to get your bitmaps to print OK. For text, you need to use a function that takes a DC and allows you to specify a font size in points. I think CFont has CreatePtFont, but I'm not sure ( it's something like that, but I learned about it here about a week ago ). In GDI+ you specify fonts in points automatically. When I moved to GDI+ I finally got all my fonts perfectly as I requested them, the same in my preview ( which I draw myself in a seperate function ) and my page. This is essentially because GDI+ IMHO behaves more as I expected it to in terms of the size of the font returned ( although it just may have been because I'd never discovered CreatePtFont ).
Sorry if this rambled a little - if you need more info, just ask. I can post some code to do it tomorrow at work if you're still stuck.

Hi,
I am working with Disconnected Recordsets in a Component Function.I am passing the Recordset pointer from the Server to Client.There is no problem here.However , when I run the client for the First Time the Connection and Recordset objects are opened and I can get the records at the client(The server maintains these Records in MS Access DB).When I run the client for the second time and so on I get the COM error that "The application requested an operation which cannot be performed on an Object which is already open ".The error is due to Recordset opening at the start of the function .But, I am closing the REcordset at the client side.
How should I open and close the REcordset in that case to avoid this error ?
Thanx in advance for the help .
Regards,

How can I paint all the components of a CFrameWnd without using bitmaps?

DrawFrameControl() can be used to draw caption buttons, scollbar buttons etc. If that is what you meant.

How do you add the current date on to the project using COleDateTime? And where do you add the code?
Nicole
|
|

|

Where do you want to add the date ? In your about box ? The menu bar ?
GetSystemTime will give you the info you need, COleDateTime has a constructor that takes this info if you *need* this object for some other reason and what you do with it depends on what you want to do with it.

Well, thats kinda what I meant, it's close. But I really meant how to draw that stuff on there. And I don't wanna just use the windows frame components I wanna make my own version of them and then paint them on the Frame window.
|
|
|
|
|
Ah - so you're not really that interested in the date, you want to draw your own window frame ?
WM_NCPAINT is the message you want to catch - it indicates you want to paint the non-client area of a window (i.e. the frame).

Hi,
I need a dialog window to display controls in more than
one screen. I check the scrollbar in the property of the dialog.
But when the program run, I still only can get one screen display
no matter how I move the scroobar. What's the reason for the problem?
Thanks for your help!

Are you saying you actually want to move the other controls within the dialog box by means of the scroll bar?

Hello. I am using ODBC to connect to an access database. I have a treectrl in my application that lists all of the records from a particular field in the database. I need to be able to click an item in the treeview and switch to the corresponding record of the item clicked. I already know how to get the item clicked in the treeview, but now I can't figure out how to switch to the record that was clicked in the treeview. I'm also not sure I am going about it the best way. Right now I am attempting to use a filter, which I thought was easy, but I can't get it working for the life of me. I'm sure I'm missing something easy. Could someone lend some help. Thanks in advance. Here is some of the code from the OnSelchangedTree class which gets the item clicked in the treeview. (Should my filter code be somewhere else?)
m_pSet->m_TestParam=text; // the item clicked in treeview
m_pSet->m_strFilter = "[Test] = ?";
m_pSet->Requery();
My program compiles, but when I click on an item in the treeview it gives me a popup message saying "Too few parameters : Expected 2".
Thanks for any help.

If I remember correctly changing the where (filter) or order by (sort) clause in an ODBC recorset makes the Requery equivalent to a Close and Open with a new sql query string, so you can try that route without losing anything. If you've used the MFC wizard for the class, you're limited to a SELECT * or whatever's set up in the RFX stuff (i.e. same cols as in DoFieldExchange) but you can override GetDefaultSQL to fiddle a bit with WHERE clauses and the like.
But I'm not sure the requery is what you want in this context. You want to make the record current and display the data.
Hmmm - you might want to look at the DDX_FieldLBIndex function - no experience with it myself, just came on it in the MSDN. If there was something of this sort for a tree you'd be set, I think - or maybe a list is a better paradigm.
With the tree, worst case, you'd end up cycling through records till you found the one the user clicked on wanted then you'd display it. This is what the DDX_FieldLBIndex saves you from, I think, unless you want to cache all the records before displaying the tree.
later...
Oops - now that I think of it, you should be able to cache the record number and Move to it - maybe as itemdata in the tree. Might need code to check in case another user deleted it - see IsDeleted.

Hello, the codegurus around the world.;)
As long as you search the string, you need 'search_word' format.
However, you search the number, you don't need ' '.
Also, this rule may depend on the database type.
If you use Access database, you need this.
The below code is used for Access Database.
CString msg, strSQL;
long id;
m_pSet->Close();
int result = keyword.Compare("[ID]");
if(!result) {
id = atol(m_searchword);
}
if(status){
if(!result) strSQL.Format("%s = %d", keyword, id);
else
strSQL = keyword+ " = '" + m_searchword + "'";
msg = "No matching records to "+m_searchword;
}
else {
if(!result)
strSQL.Format("%s Like '%d%s'", keyword, id, "*");
else
strSQL = keyword + " Like '" + m_searchword + "*'";
msg = "No matching records begining by " + m_searchword;
}
m_pSet->m_strFilter = strSQL;
m_pSet->Open();
Have a nice day!

Thanks. I got it working using the code I already had actually. My problem was that I was returning zero records because my hItem was of the type char whereas my access database record was of the type CString. So, I took care of that and my code worked!! : )
However, now when I Requery, the arrows at the top of the program to move to the next or previous record remain accessible for clicking even though there is only one record that matches the filter. When it is clicked, then all the buttons are "greyed" out. Any ideas? Thanks again.

I've been reading pages and pages of the old posts here, and it seems people are using OnPaint to do the drawing at times.
In Class Wizard (VC++5), when I select WM_PAINT message the info box explicitely says:
"Indicates a window frame needs repainting (do NOT use for views)
So this means, they don't want us to override it in View class? For this reason, I have only used OnDraw so far to draw EVERYTHING. Am I missing something here? Whats the difference between OnPaint and OnDraw?? Thank you.

OnPaint is a WM_PAINT handler. OnDraw is an MFC construct that lets you use the same code for drawing on the screen and printing. Notice how OnDraw has a CDC* paramter - MFC sets up the device context correctly for you and passes that to OnDraw.
So yes, OnDraw is the right function to use.

ahh I see. Thanks, that's clear. So I just ignore WM_PAINT OnPaint then, and get on with OnDraw. It's puzzling though, when people talk about OnPaint... They might just as well say OnDraw in the first place if thats what they're referring to by OnPaint or WM_PAINT...
Thanks again.

If you use OnPaint, you can select when the device context is called, by moving the call to CPaintDC. This is useful because there is no point in double buffering if you draw to your memDC and the screen has been blanked by CPaintDC - you still get flicker.
The alternative is to do your double buffering in OnPrepareDC, which is called prior to OnDraw and the DC from OnPrepareDC is passed to OnDraw. However, as a lot of examples use OnPaint, it's hardly surprising that a lot of people use it as well ( myself included from time to time ).

So, there's no point in double buffering in OnDraw?? What I've done so far is to use memDC to do rendering then BitBlt to pDC, and also override WM_ERASEBKGRND to prevent erasure of background.
So what I should do is to use OnPaint instead, don't override OnEraseBkgrnd, and draw using memDC (backbuffer) then at the VERY last minute I call CPaintDC (causing screen blank) to get dc for BitBlt?
