如何用其他程序启动CAD并加载arx程序同时打开dwg文件

vager

请高手指点!

fpgzs

在启动目录在创建一个ACAD.RX文本文件，里面写上要加载的ARX文件名，每个文件占一行!

        STARTUPINFO si = {0};
    si.cb = sizeof(si);
        PROCESS_INFORMATION pi;
        BOOL bRetVal;

        bRetVal = CreateProcess("AutoCAD可执行文件所在路径 '同时打开dwg文件名'", NULL, NULL, NULL, FALSE, 0, NULL,
                                                        "启动目录：ARX文件所在路径", &si, &pi);

        if (!bRetVal)
        {
                AfxMessageBox("启动CAD失败！");
        }

用VB的方式要简单些！

用Vc也很简单
自动加载arx程序

AcadApp::ErrorStatus

acrxRegisterApp(

AcadApp::LoadReasons alr,

const char * logicalName,

const char * regPath,

int regkeyindex,

bool bDwgU = false);

alr Input load reason (or multiple, logically ORd load reasons) that should apply to the application. If multiple load reasons are logically ORd, the result must be cast to the type AcadApp::LoadReasons.
logicalName Input logical name for ObjectARX or ObjectDBX program to load
regPath Input registry path to where the application's demand load information is located
regkeyindex Input index of rootkey string to prepend to regPath
bDwgU Input Boolean indicating whether to register the application under the Autodesk/ObjectDBX area of the registry

This function will make an entry in the "Applications" subkey tree of AutoCAD's section of the HKEY_LOCAL_MACHINE part of the system registry. The entry's key will be logicalName and will have two subkeys for each of the values reasons and regPath.

regPath should be a path in the system registry to where your application-specific command demand load entries, path and file name of your ObjectARX application, and logical name for your application are located. It must not include the rootkey since that will be prepended based on the reKeyIndex value. logicalName will be appended onto the end of regPath before writing it to the registry.

regkeyIndex is an index indicating which of the following root key strings will be prepended to regPath before writing it into the registry as the string entry for the regPath subkey value under the logicalName key:

0 for the string "\\\\HKEY_CLASSES_ROOT"

1 for the string "\\\\HKEY_CURRENT_USER"

2 for the string "\\\\HKEY_LOCAL_MACHINE"

3 for the string "\\\\HKEY_USERS"

For example, if AutoCAD's section is:

HKEY_LOCAL_MACHINE
    SOFTWARE
        Autodesk
            AutoCAD
                R14.0
                      ACAD-606348324:606348324then

acrxRegisterApp((AcadApp::LoadReasons)(AcadApp::kOnProxyDetection |
AcadApp::kOnCommandInvocation), "TestApp", "SOFTWARE\\MyApps", 2);

will result in the following:

HKEY_LOCAL_MACHINE
    SOFTWARE
        Autodesk
            AutoCAD
                R14.0
                    ACAD-606348324:606348324
                        Applications
                            TestApp
                                LOADCTRLS: REG_DWORD: 0X5
                                REGPATH: REG_SZ: \\HKEY_LOCAL_MACHINE\SOFTWARE\MyApps\TestAppand AutoCAD will expect to find "Commands", "Loader", and "Name" keys with entries under them at \\HKEY_LOCAL_MACHINE\SOFTWARE\MyApps\TestApp. For example, such a subtree might look like:

HKEY_LOCAL_MACHINE
    SOFTWARE
        MyApps
            TestApp
                Commands
                    DOIT: REG_SZ: DOIT
                    MOVEME: REG_SZ: MOVEME
                Loader
                    MODULE: REG_SZ: MyTestApp.arx
                Name
                    TestApp
                Groups
                    GRPNAME: REG_SZ: GRPNAMEIf bDwgU is true, the application will be registered under the Autodesk/ObjectDBX area of the registry. In addition to AutoCAD, all ObjectDBX applications can search for it there.

Returns AcadApp::eOk if successful.

Returns AcadApp::eKeyExists if an entry already exists and cannot be overwritten.

Returns AcadApp::eRejected if the write could not be completed.
