You can easily add build configurations in to your project VC7 so that the same project builds ObjectARX modules for both AutoCAD 2000/2002, and AutoCAD 2004, but the trick is to force VC7 to build your AutoCAD 2000/2002 target with the correct headers and libraries. In addition, you have to make sure your source code compiles correctly with both old and new ObjectARX SDK versions. This will likely require some conditional compilation if your code uses parts of the SDK that have been modified in ObjectARX 2004.
Input point monitors are invoked for all string and digitizer events when a point is being acquired, or when forced entity picking is enabled. Input point monitors can view the final point position and can display a ToolTip string. The ToolTip string can be set by using the appendToTooltipStr and additionalTooltipString parameters when creating the input point monitor.
You have two option for migrating your apps : restart from scratch (and see , already posted), or add new features by maintaining a mapping layer between the C++ and C# code. While C# is quite good as far as calling native code go, it's still some pretty complex code to write. If you either use P/Invoke or C++/CLI, both will force you to know much deeper detail about the platform than would be required for a pure C# solution. Also, you'll spend an awful lot of time marshalling data between managed and native code. A better option may be COM, though I hope you like ATL programming.
AutoCAD Toolsets such as AutoCAD Architecture or AutoCAD Map 3D include one to many workspaces beyond the default AutoCAD workspace. You can force a specific workspace, such as the Map 3D Planning and Analysis workspace to load every time you open Map 3D with the /W switch. Additionally, this switch is also helpful if you have client-specific interface customizations (such as a custom Ribbon tab for client-specific LISP routines).
We will introduce a new data type: ads_name. This type of data is used to save the results of successfully selected objects. Generally, the object is selected
Users can obtain and modify the object features. The old ads and modern API ObjectARX are completely different. Before discussing the differences between ADS and ObjectARX in acquiring object data, let's take a look at the definition of ads_name.
The ads_name data type isArray of two long ElementsTherefore, you cannot use the value assignment operator to make an ads_name object equal to another ads_name object. This is similar to the ads_point data type mentioned above. Just like the ads_point data type,
2.Acedentsel ()[Ads_entsel ()], acdbentget () [ads_entget ()], acdbentmod () [ads_entmod ()], acdbentupd () [ads_entupd ()]
Remember that the selection set is also an ads_name object (I know this may cause a lot of confusion ). We will soon discuss the selection set. As mentioned above, ads and ObjectARX are completely different in obtaining and changing object data. We will discuss the ObjectARX method in the following sections.
Acdbentget ()The function returns a single-chain table in the result buffer. You can use the rbnext field of the resbuf object to traverse and detect the linked list of the result buffer. If Rb is a resbuf result buffer, the syntax is as follows:
You can also change the values in some result buffers. After the final result is complete, call the acdbentmod () function to modify the internal data of the object. As you can see, this function requires a resbuf object. You can use
The acdbentupd () function is used to observe the modification effect of each acdbentmod () function call. In essence, adsrx is used to process the linked list of the result buffer. The ObjectARX method is completely different from this method, and the difference is huge. For users with large amounts of old data, because of adsrx, these functions can still be used in ObjectARX (Autodesk put ads in ObjectARX ). Since this book is about ObjectARX, the discussion of acdbentget (), acdbentmod (), and acdbentupd () functions ends here.
Return to the acedentsel () function because it is still widely used in ObjectARX. The definition of the acedentsel () function is described as follows:
The acedentsel () function stops running and waits for user input. The entity name is returned in entres, and the point used by the selected entity is returned in ptres. The STR parameter specifies the string displayed before the acedentsel () function is paused. The STR parameter is optional. If it is null, AutoCAD displays the default prompt "select objects :". When you specify a complex entity to respond to the acedentsel () function, the title of the multiline or block is returned. If the acedentsel () function is successfully called, rtnorm is returned. If the call fails, rterror is returned. If you cancel the call (Press ESC), rtcan is returned. The acedentsel () function can be used with the acedinitget () function, as shown in the previous example.Code. How is the acedentsel () function used in ObjectARX? AutoCAD uses graphs as databases for processing. Each entity in each open AutoCAD drawing has a unique AutoCAD database object ID associated with it. With the ID number of the object, we can open the AutoCAD entity to determine the type of entity to be processed. Then we can use the object acquisition and setting method (function) to operate the object. Once an ads_name object is available, we can obtain the ID of the associated AutoCAD database object (Data Type: acdbobjectid ).
The following is the function definition for obtaining an AutoCAD database object ID: The ads_name object is the result of the success of selecting an object using the acedentsel () function.
The following is a piece of ObjectARX code using the acedentsel () function: This function returns the acdbentity pointer with the pent. note how to use the acedentsel () function to select an AutoCAD entity.
Take a look at the acdbentlast () function. AutoCAD always knows the recently generated object, which can be found through the acdbentlast () function. The acdbentlast () function is defined as follows:
The acdbentlast () function finds the nearest entity in the graph, and stores the most recent (undeleted) primary entity name in the graph database into the result. It can be selected even if the nearest object is outside the screen or on a frozen layer. The most recent entity refers to the recently created entity, soThe acdbentlast () function can be used to obtain the entity name of the entity just added to the AutoCAD database.If the acdbentlast () function is successfully called, rtnorm is returned; otherwise, rterror is returned.
For complex entities with blocks and multi-segment lines, ADS FunctionsAcednentsel () and acednentselp ()(Representing the selection of nested entities) Select attributes (assuming that a block entity is selected and the attributes of the block have been defined) and vertex information (assuming that a multiline is selected ). Compared with the acednentsel () function, Autodesk recommends the acednentselp () function. The acednentselp () function adds updated content than the acednentsel () function, so we only discuss the acednentselp () function.
Below isAcednentselp ()Function Definition: this is a complex function with many parameters. The acednentselp () function pauses running and waits for user input. It returns an entity name (saved to entres) and a vertex (saved to ptres) used to select an entity ). The value of pickflag is false or true, which is used to specify whether the acednentselp () function can interact with humans (that is, allows users to select the point corresponding to the input point ). If the value of pickflag is false, the acednentselp () function prompts you to specify an object. The initial value of the ptres parameter is ignored. If the value of pickflag is true, the initial value of ptres is used to select an object. I have almost never used pickflag to be true. For details about other parameters, see adsrx. If STR is null, AutoCAD uses the standard "select objects: "
Prompt. The parameter I'm most interested in is entres, which stores one vertex or attribute.
3.9 applications Program Further analysis of the key points of the Instance
The acedgetxxx () class function is used after the first circle is created in the application instance maid. Now let's take a look at these functions. In the while loop, we ask whether you need to draw another circle. As long as the user does not answer "no", it will constantly ask the user to draw circles. Let's take a look at the first two rows of the while loop:
The keyword table in the acedinitget () function is "Yes No". The first parameter is null, so we can accept null input. We could have used rsg_nonull to force users to enter "y" or "N ". In general, the default options of AutoCAD are represented by Angle brackets. Here is . If you enter "Y", the kW value of the string is "yes ". If you enter "N ",
", The kW value will be" no ". However, if you press enter only, KW is an empty string. In this case, the rtnone case of the switch statement is used to copy "yes" to the kW buffer zone. Remember that the acedinitget () function only applies to the acedgetxxx () class function that follows it. When you run the application again, try to enter some letters that are not "y" or "N ".
Generated. You will receive a prompt repeatedly until you press y, N, or enter.
If you want to draw a circle, the program will go to the else branch of the IF statement and ask the user to select the center of the circle, as shown in the following code:
Here, rsg_nonull is used to call the acedinitget () function, because we need to select a center. In the next acedgetpoint () function call, note that the first parameter is null. Remember that in the acedgetpoint () function, the first parameter can be used as a reference point for selecting a vertex. This is the first point, so we use null. If you want to select the center of the circle, try to press ENTER
Key, and the system will prompt you to select the center of the circle again.
When the circle radius is input, we use the acedgetdist function to replace the acedgetpoint () function, because the response of the acedgetdist function allows us to select a point or enter a distance value from the keyboard. The following code uses the acedgetdist () function:
Note how to use the combination of rsg_nonull, rsg_nozero, and rsg_noneg to call the acedinitget () function. This is because we need to use the acedgetdist () function that follows the setting of the acedinitget () function. The first parameter in the acedgetdist () function is CP, which is the previously selected point. A rubber band line is drawn from the point CP. After the second point is selected
The distance from the point CP to the second point is saved to the variable rad, which is a variable of the ads_real data type. However, you can also press a value on the keyboard. We do not allow zero and negative input, which is why rsg_nozero and rsg_noneg are also included when the acedinitget () function is called.
In the User-Defined printentinfo () function with an ads_name parameter, we call the acdbentget () function to retrieve the result buffer list. If the call is successful, the result buffer linked list contains the data structure of the object, as shown in the following code segment:
We use the rbent-> rbnext field to traverse the table and check the value of the rbent-> restype field. This field indicates the Data Type stored in the rbent-> resval field.
