Re: FindStringExact().. Tomasz Sowinski22-Mar-02 1:45 Tomasz Sowinski 22-Mar-02 1:45  While there's a possibility that you've found a Windows/MFC bug, I'd suggest reviewing your code. Maybe you have some spaces before/after numbers, etc. Tomasz Sowinski -- http://www.shooltz.com ** If you're going to rape, pillage and burn, be sure to do things in that order. ** Re: FindStringExact()..

Tomasz Sowinski22-Mar-02 2:09 Tomasz Sowinski 22-Mar-02 2:09  Try with setting 1st param to -1 instead of 0. If this doesn't help, try to output strings with TRACE and CComboBox::GetLBText.

Carlos Antollini22-Mar-02 2:17 Carlos Antollini 22-Mar-02 2:17  You need to start from -1 if you want that find the string from the beginning... Neha wrote nIndex=m_combo.FindStringExact(0, the_resstring); You are informing 0 and not -1.... Regards Carlos Antollini. Sonork ID 100.10529 cantollini Re: FindStringExact().. Tomasz Sowinski22-Mar-02 2:24 Tomasz Sowinski 22-Mar-02 2:24  Well, according to MSDN the search wraps at the end of combobox and starts from the beginning if you pass non-negative value, so it should have no effect. But it's worth trying anyway.

Taking care of scroll position 21-Mar-02 23:52 21-Mar-02 23:52  I have a problem while creating the Bitmap for an image not displayed on my view..... I create a Bitmap of my current view.. this is done perfectly as it takes care of the scroll position and other factors... but i want to create a bitmap of another image, which is not displayed on my current view. While creating this second bitmap, it has to be created with reference to the scroll position of my first Bitmap ... The object of creating this second Bitmap, is to map both index positions of the 2 bitmaps correctly, so that one bitmap can be merged into the other Thank You MFC Tictactoe alpha-beta pruning bug... John Cruz21-Mar-02 23:35 John Cruz 21-Mar-02 23:35  can anyone help me find my bug. i wrote a function that would search the tictactoe board for the best possible computer move. i am using alpha beta pruning to optimize my search. the function returns the score from the search and the row and column where the computer should move. ok here is the function... the PossiblePlayerMove function is the same thing but it searches for the best possible player move. int CComputer::CheckForMoves(const CBoard &rConstBoard,int nDepth, int nAlpha, int nBeta, int &nRow, int &nCol) { // Check for invalid data ASSERT(mnDepth >= 0 && mnDepth <= MAXDEPTH); // Check if the row and column return is a valid value ASSERT(nRow < MAXROW && nCol < MAXCOL); int nScore = 0; // The score from the search mnDepth = nDepth; // Set the Depth to the new depth. int Row = nRow; // Copy the Row and Column int Col = nCol; // Create a new Board and Copy the values of other board. CBoard Board = rConstBoard; // Base Case if (Winner(Board) || mnDepth == 0) { nRow = Row; nCol = Col; return Evaluate(Board); } else { // Try all the possible move on a different Board // then return the best move. for (int row = 0; row < MAXROW; row++) for (int col = 0; col < MAXCOL; col++) if (Board.IsEmpty(row,col)) { Board.SetCellValue(row,col,'O'); if (mnDepth == 0) break; nScore = PossiblePlayerMove(Board,mnDepth - 1,nBeta,nAlpha,Row,Col); // Set Row and Column nRow = Row; nCol = Col; if (nAlpha < nScore) nAlpha = nScore; Board.SetCellValue(row,col,NULL); if (nAlpha >= nBeta) break; } } return nAlpha; } i hope this is enough... by the way.. the possible moves function is the same thing ...

By the press of one button thanks Re: clearing boxs Jon Hulatt22-Mar-02 0:10 Jon Hulatt 22-Mar-02 0:10  You'd need to write that yourself, becuase noone knows which edit boxes and how many are in your dialog. Just SetWindowText() them all to a blank string. Sorry to dissapoint you all with my lack of a witty or poignant signature.

I always roll my own, because otherwise the user gets a million 'please enter a number dialogs in inappropriate times - for example if I empty the dialog I'll get one before I type in a new number.

DDX is Dialog Data Exchange and it's a MFC way of moving data between member variables of your dialog class and dialog controls. Are you using MFC?

But let's assume that this is the case. You need to use ClassWizard. On its second tab you can add member variables to your dialog class - each element you want to be cleared should be associated with variable. In your 'reset' handler you should reset the variables to appropriate initial values and call UpdateData(FALSE).
