OK, I found out the reason. 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++?

Shakesbeer String Class Operations Aidman5-Apr-03 12:31 Aidman 5-Apr-03 12:31  Is it possible to create a string/char-array class with overloading operations that could preformed these operations?: String = “Hello ” + “World”; Where two constant strings/char-arrays “Hello ” and “World” adds and inserts into the String class. So that the class String will contain the string/char-array "Hello World".

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++"?

The buttons in the same toolbar however are not aligned in the middle of the toolbar. It stays the top. When the size of the band is bigger than a button's height, it doesn't look very elegant. But if you look at IE toolbars, like the Address bar, when its height is bigger, the Go button stays in the middle. Does anybody know how to do that? The toolbar is similar to the one described by http://www.codeproject.com/atl/ietoolbartutorial.asp Thanks. VC++ BG Color Makover5-Apr-03 8:22 Makover 5-Apr-03 8:22  This is kind of off-topic so.... What is the prefered background color in order to reduce the strain on the eyes. The setting goes through properties->appearance... (just to clarify what I mean) under MS Win (or maybe under VC properties). Maybe each and one of you have different prefered color but is there a standard for this Sorry about the lousy English. ----------------------- Go USA Go Re: VC++ BG Color Nish Nishant5-Apr-03 9:23 Nish Nishant 5-Apr-03 9:23  I would think white would be best.
