PRB: Using the SelPrint Method of the Rich Text Control

• Microsoft Visual FoxPro for Windows, versions 5.0, 5.0a on the following platforms: NT, Win95

SYMPTOMS

The example code from Help for the SelPrint method of the Microsoft Rich Text Control causes syntax errors when saving after it is pasted into the Click method of a command button as directed by Help. Additionally, once the syntax errors are fixed, the contents of the Rich Text control do not print on the Windows 95 platform but no error messages are received.

CAUSE

The example code in Help for the SelPrint method of the Microsoft Rich Text control is Visual Basic code.

Even after converting this code to Visual FoxPro code, the contents of the Rich Text Control cannot be printed on the Windows 95 platform. The specific cause of this behavior is under investigation.

RESOLUTION

The example code for the SelPrint method can be changed into the following Visual FoxPro code to eliminate the syntax errors and get the contents of the Rich Text control to print when Visual FoxPro is running on the Windows NT 4.0 platform.

As stated in Help, the following code should be placed in the Click method of a command button. A CommonDialog control should also be placed on the form with a command button and a Rich Text control:

   cdlPDReturnDC=256
   cdlPDNoPageNums=8
   cdlPDSelection=1
   cdlPDAllPages=0

   Thisform.CommDlg1.Flags = cdlPDReturnDC + cdlPDNoPageNums
   If Thisform.RTF1.SelLength = 0
   Thisform.CommDlg1.Flags = Thisform.CommDlg1.Flags ;
   + cdlPDAllPages
   Else
   Thisform.CommDlg1.Flags = Thisform.CommDlg1.Flags ;
   + cdlPDSelection
   EndIf
   Thisform.CommDlg1.ShowPrinter
   Thisform.RTF1.SelPrint(Thisform.CommDlg1.hDC)

STATUS

Microsoft is researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

The name and version of the Rich Text control varies depending on which version of Visual FoxPro or Visual Basic has been installed on the computer.

Look in the Tools, Options dialog box, Controls tab in Visual FoxPro to check which version of a control is installed. Unfortunately the dialog box displaying the controls is not wide enough to show the version number of the Rich Text control. The actual file version can be obtained by viewing the properties of the .ocx file in Windows Explorer.

The Microsoft Rich Textbox Control, version 1.0.2922, is installed by Visual FoxPro 5.0. The file name is Richtx32.ocx and is found in either the Win95\System or the WinNT\System32 folder depending on the operating system.

The Microsoft RichText Control, version 5, version 5.00.3714, is installed by Visual FoxPro 5.0a. It is also named Richtx32.ocx and is found in the same locations as the version installed by Visual FoxPro 5.0.
