If the value of BITMAP-HANDLE is 0 or negative, an error has occurred. These errors are defined in acugui.def.
| Error | Value | Description |
|---|---|---|
| WBERR-UNSUPPORTED | 0 | The system does not support bitmapped images. Currently, ACUCOBOL-GT supports the display of bitmaps on Windows systems only. |
| WBERR-FILE-ERROR | -1 | A file error occurred when trying to open name. The most common cause is that name does not exist. Other possibilities include a permissions error or running out of file handles. |
| WBERR-NO-MEMORY | -2 | The system ran out of memory trying to allocate space for the image. |
| WBERR-NOT-BITMAP | -3 | The named file does not contain a device-independent bitmap. |
| WBERR-FORMAT-UNSUPPORTED | -4 | The format of the current image is not supported. |
| WBERR-MISSING-DLL | -5 | The runtime has attempted to load a .jpg file and the file ajpg32.dll cannot be found |
| WBERR-INVALID-HWND | -6 | The runtime cannot capture the current image. The window handle provided was invalid. |
| WBERR-INVALID-DATA | -7 | The runtime cannot access the bitmap object. This can happen if the window has been closed, or if the image is corrupt. |
| WBERR-INVALID-CLIPBOARD | -8 | The runtime has been denied access to the clipboard. This may be because another application has locked the clipboard. |
| WBERR-INVALID-PALETTE | -9 | The runtime is not able to create the palette for this image. The most common cause is that the image is corrupt or has a palette size that is not supported. |
