    Transfer Data between C++ and Excel

    The simple way is: Create a file in '.csv' or '.slk' format. Then open the file with 'ShellExecute' command. NOTE: These formats don't support graphs, only data.

    Disable System Keys?

    This problem only occurs in Dialog Based Projects, or in dialogs. You can overwrite the OnCancel() function: void CYourDlg::OnCancel() { } then change the id of the cancel-button and add to this button the original OnCancel: void CYourDlg::OnCancel() { CDialog::OnCancel(); } In...

    Converting Micro-Focus To RM/Cobol-85

    Thanks Betty, In fact you can use both in MF-Cobol: pic 9(02) comp-x. pic x(02) comp-x. comp-x is used to store unsigned binary data. If you use 'pic x' the physical size of the item is exactly the size you define, and if you use 'pic 9' the size is calculated: pic x(02) comp-x is 2 bytes. pic...

    Converting Micro-Focus To RM/Cobol-85

    Obviously Betty never worked with MF-cobol. Pic x(2) comp-x copiles very well. I would appreciate she first checkes things before acusing me of puting code on this forum that will give compile errors.

    Converting Micro-Focus To RM/Cobol-85

    In MF comp-x is unsigned binary starting with the high-order bytes. For example: pic x(4) comp-x value 1 would be hex: 00 00 00 01 pic x(4) comp-x value 255 would be hex: 00 00 00 FF so: pic x(1) comp-x is 1 byte maximum value 255. pic x(2) comp-x is 2 bytes maximum value 65535. pic x(4)...

    Best way to run an external program.

    OK, this code works with notepad: it will put your executable in the foreground, in the clients rectangle: STARTUPINFO si; PROCESS_INFORMATION pi; memset(&si, 0, sizeof(si)); si.cb = sizeof(si); si.dwFlags = STARTF_USESHOWWINDOW | STARTF_USEPOSITION | STARTF_USESIZE...

    how can I auto-validate a dialog after it displays?

    in OnInitDialog: SetTimer( 1 , 100 , NULL ); Add WM_TIMER and then: void CYourDlg::OnTimer(UINT nIDEvent) { if ( nIDEvent == 1 ) { KillTimer( 1 ); AfxMessageBox( ........... ); } CDialog::OnTimer(nIDEvent); }

    Is it numeric

    If you create a derived class from CEdit and overwrite the fuction OnChar() ( WM_CHAR ) than you can prevent alpha-characters coming in to the control: void CYourClass::OnChar(............) { if ( nChar < 48 || nChar > 57 ) { MessageBeep( ( WORD ) ) - 1 ); return; }...
