help with DirectX Steven M Hunt5-Apr-03 16:50 Steven M Hunt 5-Apr-03 16:50  Hi. I have a VERY basic DirectX program from a book and every time i have tried to compile it, i get an unresolved external symbol error on IID_IDirectDraw7. My friend had the same problem with DirectX. I included ddraw.h and ddraw.lib(using the linker), what could possibly be causing the problem? -- Steve Re: help with DirectX Philip Patrick6-Apr-03 1:43 Philip Patrick 6-Apr-03 1:43  Don't remember what I "libbed" for it, but I did a text search for this symbol in all LIB files in DirectX and then tried to link each of returned one by one.

Steven M Hunt6-Apr-03 11:21 Steven M Hunt 6-Apr-03 11:21  I found the problem when searching through a basic DirectX code example on this site. Aparently the book forgot to mention dxguid.lib, which supports the definition of IID_IDirectDraw7. -- Steve Making a large bitmap fit in a CDialog or CFormView? DanYELL5-Apr-03 16:24 DanYELL 5-Apr-03 16:24  I have a large bitmap. I can condense the bitmap's size and make it display in a dialog, but then the picture is fuzzy. It's fuzzy before I add it to a bitmap. I can make the large bitmap appear with scrollbars, but it doesn't look right. Is there any way to take a large bitmap and make it appear naturally and clearly within the dialog? Please any response any one can give me will be greatly appreciated. Code is always appreciated.

Shakesbeer Odd behavoir of ::EnumChildWindows Abin5-Apr-03 14:18 Abin 5-Apr-03 14:18  I'm trying to enum all child windows of a given non-null parent window, so I use ::EnumChildWindows. I have defined a callback func BOOL CALLBACK EnumChildProc(HWND hwnd, LPARAM lParam) and passed it to ::EnumChildWindows as the second parameter. The problem is that ::EnumChildWindows always returns FALSE and the callback function EnumChildProc never gets called no matter what. I then call ::GetLastError to check the trouble, but it returns 0, which means "operation completed successfully" is it not? So what gives? Thanks.

So what gives? Are you running Win9x? According to MSDN, any windows functions that are actually implemented as 16 bit code will not set the last-error code. Window management functions are among those that don't.

Abin6-Apr-03 13:31 Abin 6-Apr-03 13:31  That's because the window I passed in to ::EnumChildWindows does not have any child window... MSDN only said ::EnumChildWindows returns zero if failed, but did not say it also returns zero if all child windows have been enumerated.

Write this Method an call it in OnPaint(); First you have to add the Bitmap to your Resources void Classname::PaintPic(){ CBitmap pic; CWnd* wp = GetDlgItem(IDC_STATIC_BITMAP_GLASROHR); CDC *pDC = wp->GetDC(); CDC imageDC; imageDC.CreateCompatibleDC(pDC); rohrbild.LoadBitmap(IDB_BITMAP_ROHR_GETELLERT); imageDC.SelectObject( &pic); //here chose dimensions and offset pDC->BitBlt(3, 3, 400 , 200, &imageDC, 0, 0, SRCCOPY); imageDC.DeleteDC(); wp->ReleaseDC(pDC); } Re: How can I load a picture (jpg or bmp) into Picture Property with VC++? ATC6-Apr-03 5:14 ATC 6-Apr-03 5:14  Hi Heiko, Thank you for your guide, but can you help me a bit more? Let say I have a "Mypicture.bmp" ... how can I do like you said: "First you have to add the Bitmap to your Resources"? Many thanks Re: How can I load a picture (jpg or bmp) into Picture Property with VC++? Heiko20036-Apr-03 7:45 Heiko2003 6-Apr-03 7:45  Ok, I will try Click Insert->Ressource Click on Bitmap then the Button Import Browse to you disired file (Mypicture.bmp) (if you could not see the file in the directory don't forget to chose all files (*.*) ) Now you have added a Bitmap Ressource from a file. now you can use the methode i've copied call it in the Dialogmethod OnPaint. You can add the OnPaint method with the aid of the classwizard. (The Message who calls this method is WM_PAINT) I hope now that i could help you otherwise ask again Heiko Re: How can I load a picture (jpg or bmp) into Picture Property with VC++?

You just have to overload the + operator and the += operator. In fact taking a look at the CString source might help you. There are also some very good non-MFC CString-type classes here on CodeProject.

If I get your question, the answer is no, you cannot overload + to concatenate two char arrays. At least one argument must be a user-defined type. --Mike--    THERE IS NO     THERE IS NO    BUT THERE IS MAGIC PIXIE DUST  BUSINESS GENIE  CODE PROJECT Homepage | RightClick-Encrypt | 1ClickPicGrabber "You have Erica on the brain" - Jon Sagara to me Re: String Class Operations Aidman5-Apr-03 18:49 Aidman 5-Apr-03 18:49  Michael Dunn wrote: What do you mean by "pure C++"?
