L_LTSCR_API L_INT L_CaptureFromExe(pBitmap, uBitmapStructSize, pszFileName, nResType, pResID, bCaptureByIndex, clrBackGnd, pfnCaptureCallback, pUserData)
Captures an image from the specified resource stored in an EXE or DLL.
Pointer to a bitmap handle that references the captured data.
Size in bytes, of the structure pointed to by pBitmap, for versioning. Use sizeof(BITMAPHANDLE).
Character string containing the name of the exe (or dll) from which the resource should be captured.
Specifies the type of resource to capture. Possible values for RETYPEENUM are:
|RESTYPE_BITMAP||Capture a bitmap resource|
|RESTYPE_ICON||Capture an icon resource|
|RESTYPE_CURSOR||Capture a cursor resource|
Specifies the index of the resource to capture. You can use MAKEINDEX or MAKERESOURCEID macros to convert the resource ids to strings.
Flag of the requested resource. Possible values are:
|TRUE||Indicates that pResID is the index position of the requested resource.|
|FALSE||Indicates that pResID is the resource ID of the requested resource.|
Background color for icons.
Optional callback function for additional processing.
If you do not provide a callback function, use NULL as the value of this parameter. If you do provide a callback function, use the function pointer as the value of this parameter. The callback function must adhere to the function prototype described in CAPTURECALLBACK Function.
Void pointer that you can use to pass one or more additional parameters that the callback function needs.
To use this feature, assign a value to a variable or create a structure that contains as many fields as you need. Then, in this parameter, pass the address of the variable or structure, casting it to L_VOID ;*. The callback function, which receives the address in its own pUserData parameter, can cast it to a pointer of the appropriate data type to access your variable or structure. If the additional parameters are not needed, you can pass NULL in this parameter.
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
This function is similar to L_CaptureFromExeDlg, but does not display a dialog box. It simply captures the resource identified by nResType and pResID, from pszFileName. The captured bitmap may or may not have a region, depending on the transparency information of the captured resource.
Use L_CaptureGetResCount to determine the number of resources in an executable.
