Took me a while to get it going, but it worked an absolute treat, thank you for the response Norm. Much Appreciated, Alan. "When I left you I was but the learner, now I am the Master" - Darth Vader:mad:

Hi again, you`ll be glad to know that I finally finished the damn programming, yay :-D . I used the CDualGridCtrl that was on this web-site (I forget the author, but whoever he/she is thanks - there will be a mention in the final project). I would have liked to use Chris's grid control, but as you said, it can accomodate all my needs with a few hours invested. I didn`t have a few hours to invest as I have to have some sort of draft ready by Monday, and I didn`t want to p*ss about on a part of the project which is insignificant, yet necessary. But thanks to all who helped, Speak soon, Alan. "When I left you I was but the learner, now I am the Master" - Darth Vader:mad:

I found an easier way. MSDN help says that, by default, the CSpin thingy's range is set to Min:100 Max:0, and by clicking the down arrow sends the current value nearer the minimum value, which is why it goes up, its heading for 100. All I did to get it to work properly was call : CDialog::DoDataExchange(etc.) { ... min , max myCSpinThingy.SetRange(0 , 10); } and it worked no problem. Just thought I`d let you know, since I wouldn`t have got there in the end if it weren't for you, Cheers Ravi, Alan. "When I left you I was but the learner, now I am the Master" - Darth Vader:mad:

In response to your answers : 1. Yep, thats why I asked if you could do it in C++. 2. Its definately the easiest function, and the most appropriate for what I want. 3. I am seriously thinking of doing your OnPaint overriding advice, cos I've had a look at Chris's non-MFC code, and I must be honest, I`m struggling to understand it. Thanks for your response though, Alan. "When I left you I was but the learner, now I am the Master" - Darth Vader:mad:

Hi all, OK I`ve managed to get it going, and am just seeking a little reassurance. What I`ve done is created a (fully filled out) BITMAPINFO structure, and a (filled it out manually) BITMAPFILEHEADER structure. I`ve then used ar.Write(theBITMAPFILEHEADER, sizeof(BITMAPFILEHEADER)); ar.Write(theBITMAPINFO, sizeof(BITMAPINFO)); ar.Write(pBits, theBITMAPINFO->bmiHeader.biSizeImage); Now, I seek reassurance cos when I compare an image that exists on my HD, to an identical copy that I saved using my app, the newly saved image is 2 bytes shorter (in at least one case). I`ve tried re-loading the new image in paint, everything seems fine, do I just leave it? Or is this a problem that could potentially send my computer kaput? Cheers all for your responses, Alan.:-D "When I left you I was but the learner, now I am the Master" - Darth Vader:mad:

Hi U can override SaveModified which is the function which gets called when the 'Save' or 'Save As' Happens, This is the function that prompts the Saving and then calls DoFileSave-->DoSave. So if u want to tailor to ur own needs i would recommend that u copy the original code and modify to tailor ur needs, U can find the source in 'doccore.cpp'(mfc src). regards, Prem

Thankyou guys, I can now finally put my mind at rest! There was me thinking my new Pentium 4 machines were bunk, when all along it was those bloody vectors! Interesting note you made with regards to the difference between an array of 10 integers and a vector of 10 Todd, even I was suprised by the excessive routine it goes through, geeze. Well, I must say cheers to all you guys for coming up with the solution, at least we all know not to use vectors in a similar situation again, AND we know why.

No worries - glad to help. Christian After all, there's nothing wrong with an elite as long as I'm allowed to be part of it!! - Mike Burston Oct 23, 2001 Sonork ID 100.10002:MeanManOz I live in Bob's HungOut now

Here's some code for changing the font in a combobox... LOGFONT lf = { 0 }; (void)lstrcpy( lf.lfFaceName, _T("MS Sans Serif") ); lf.lfHeight = -MulDiv( 10, GetDeviceCaps( GetDC()->m_hDC, LOGPIXELSY ), 72 ); VERIFY( m_font.CreateFontIndirect( &lf ) ); m_ctlCombo.SetFont( &m_font ); Best regards, Mark www.mjsoft.co.uk

After I had written the question, for some unknown reason (I`ll call it fate), this exact same solution came into my head. I was, in fact just about to delete this thread thinking that no-one would respond so quickly, amazing. I would, however, like to thank you for responding and re-affirming this solution, because it came from nowhere in my head, and I always tend to think "is this the best solution - mmmm I dunno", but since your response I have no fear. Thanks Roger, very much appreciated, Alan.:-D P.S. your solution seems pretty damn good, if thats "a bit rough" I feel quite inadequate :-D. "When I left you I was but the learner, now I am the Master" - Darth Vader:mad:

I agree with Mike, but I would make it if (m_pPointer == NULL) instead. It just looks better to me because it flows more like the way you speak the same phrase. I've never heard anyone say "If NULL is the pointer...", but instead, people say "If the pointer is NULL...".

no problem. actually, that's a chunk of code i got off of codeguru a couple of years ago - it's always worked well for me. just sharing the wealth. -c POKE 808,234

Thanks for the response Christian, I`ve decided to go and do it the Alpha Blend way, for the reasons you said. I already had a DIBSection, and the method became alot faster again. I also didn`t have to worry about masks and stuff either, which was the main problem I encountered with TransparentBlt (as Tomasz rightly pointed out). Cheers for all the help guys, very much appreciated.:-D "When I left you I was but the learner, now I am the Master" - Darth Vader:mad:

OK, I have actually managed to solve the problem, but I`d still appreciate it if you could tell me whether this code is efficient, and if not an alternative approach to solving the problem. The code below is generated from the OnAquisitionClick() function (which does all the TWAIN stuff) and passes the results to the AcquireImage() function, both of which are located in the MainFrame class of an MDI app. right here goes: void CMainFrame::AcquireImage(HBITMAP hbitmap, TW_IMAGEINFO& info) { CBitmapDoc* pBitmapDoc = NewDocument(); //new doc. CBitmapFrame* pBitmapWnd = (CBitmapFrame*)NewWindow(pBitmapDoc); BYTE* lpVoid, *pBits; LPBITMAPINFO pHead; lpVoid = (BYTE*)GlobalLock(hbitmap); pHead = (LPBITMAPINFO)lpVoid; if(pHead->bmiHeader.biCompression != BI_RGB || pHead->bmiHeader.biBitCount != 24) { GlobalUnlock(lpVoid); return; } pBits = (BYTE*)lpVoid + sizeof(BITMAPINFOHEADER); HBITMAP newbitmap = CreateDIBitmap(pBitmapWnd->GetDC()->m_hDC, &pHead->bmiHeader, CBM_INIT, pBits, pHead, DIB_RGBCOLORS); if(newbitmap) { pBitmapDoc->m_hAppliedTools.push_back(newbitmap); //stores all the layers in order for drawing later. pBitmapWnd->SetMinMaxWndSize(pHead->bmiHeader.biWidth, pHead->bmiHeader.biHeight); pBitmapWnd->AddDYNAMenu(m_hFilters, m_hTools); pBitmapDoc->SetTitle("Acquired"); m_hBitmapTemplate->InitialUpdateFrame(pBitmapWnd, pBitmapDoc, TRUE); return; } else AfxMessageBox("Cannot create new image acquisition graphic"); } The one thing I do notice is that although I get all my information from hbitmap, if I try to use that Handle, the image is not drawn at all! I think, now that I`ve got this working, I may be able to figure out some better code to the job (I noticed some areas when I was just typing it out). One other thing, hbitmap may have been ascertained from the scanner as a HANDLE and not a HBITMAP (what I mean by that is that I could pass a HANDLE to one of the TWAIN acquire procedures and it still works). The handle is then passed to the procedure above. Hope you can enlighten/reassure me on my code. Thanks again Chris, Alan:-D "When I left you I was but the learner, now I am the Master" - Darth Vader:mad:

Sorry, don`t know what you mean by "DeCSS source", so i`ll have to say no and let someone else claim credit.:-D AEGC

Many thanks Nish. I needed to know that that was the best (quickest) way of going about squaring a variable (integers). Thanks again, Alan.:-D AEGC

How do i get the library? do i have to re-install it? Would you mind if I used an implementation of your code from the WDJ site? (I was talking about that - couldn`t remember site name off top of my head though). Cheers for the response, again, Christian, Alan.:-D AEGC

I have finally found what was going wrong! I had selected the wrong hbitmap into the DIBSECTION (it was the background layer), thats why it was flicking up so quickly, it was being replaced by the new black background I just created. Just thought I`d post the solution in case anybody else has a similar problem. My thanks go Chris on majorly helping me through the subject. I`ll also thank Christian for his part on getting me on the right road to success. Cheers guys, Alan.:)
