关于F4 Help帮助窗口的参数F4METHOD的设置

本文介绍了如何解决SAP升级后F4 Help对话框变为MODAL导致的问题,提供了设置F4METHOD为Control方式的方法,并分享了修改F4IF_INT_TABLE_VALUE_REQUEST代码的步骤,以实现Modal窗口到非Modal窗口的转变。同时,文章还涉及了SAP检查ActiveX状态的代码段。

最近由于升级,sap的F4 Help对话框变成了MODAL对话框,以前编写的程序出现一些问题(DYNP_VALUES_UPDATE和F4IF_INT_TABLE_VALUE_REQUEST) 。解决办法如下:

1、用sap *用户登录系统,点击菜单HELP->Settings...->F4 Help的Display选择Control方式。该参数将存在USR05表中,将影响F4GMETHOD参数。

2、用新的登录用户登录 ,点击菜单HELP->Settings...->F4 Help的Display选择Control或者System Defaults方式。该参数将存在USR05表中,将影响F4METHOD参数。

3、修改F4IF_INT_TABLE_VALUE_REQUEST代码如下:
* immer modal laufen
*{   INSERT         PRDK900023                                        1
  IF dynp_update = space OR return_tab IS REQUESTED or
     callcontrol-pvalues ne 'D'.
*}   INSERT
  CLEAR: ocx_help_info-dynpprog, ocx_help_info-dynpro.
*{   INSERT         PRDK900023                                        2
endif.
*}   INSERT
就可将Modal窗口变为非Modaless窗口。

4、对F4METHOD和F4GMETHOD访问的SAP标准代码

### STM32CubeMX Version 1.28.1 Configuration and Usage for STM32F4 MCU In the context of configuring and using an STM32F4 microcontroller with STM32CubeMX version 1.28.1, several key points are important to ensure proper setup and functionality. #### Managing Embedded Software Packages To manage or update the embedded software packages specifically for the STM32F4 series within STM32CubeMX version 1.28.1, one should navigate through the interface by clicking on “Help” followed by selecting “Manage embedded software packages”. In this dialog box that appears, it is essential to choose **STM32Cube MCU Packages**, where updates can be applied to keep firmware libraries up-to-date[^1]. For users who have encountered issues accessing online resources due to myST login problems, obtaining a specific firmware library such as `STM32Cube_FW_F4_V1.28.0` from alternative sources allows for local installation without needing internet access during package management[^4]. However, when working with STM32CubeMX version 1.28.1, always verify compatibility between the toolchain versions and target MCUs like STM32F4. #### Debugging Interface Selection When generating projects targeting STM32F4 devices via STM32CubeMX v1.28.1, attention must be given to debugging options. By default, configurations may not automatically set up debug interfaces (e.g., SWD). Therefore, explicitly enabling these settings ensures correct pin assignments for debugging purposes similar to considerations made for other families like STM32F1 which defaults to no-debug mode unless changed[^3]. ```python # Example Python code snippet demonstrating how to check installed Cube Package version programmatically. import subprocess def get_installed_cube_version(): result = subprocess.run(['STM32CubeMX', '--version'], capture_output=True, text=True) return result.stdout.strip() print(get_installed_cube_version()) ``` This script provides a method to retrieve the currently installed STM32CubeMX version information but does not directly relate to configuring STM32F4 MCUs inside the application itself.
