我始终没有办法得到另一个程序中的右键菜单的句柄,我真怀疑这个东西是否存在
我的目的是点击另一个程序中右键菜单的某一项,给个demo当然更好了

so one method is get the menu's id . and send a message wm_command to the wnd. it's will run
你得到菜单项的ID后发wm_command给窗口
用spyxx来坚试消息,用vc打开exe文件,看看他的菜单id也行。
我试过发送wm_command消息到窗口,可以的,很感谢,但是我同样是没有菜单的句柄的.问题解决,马上给分,分不够可以再加
我要点击的菜单的条目数和内容都是变化的,如果有菜单句柄我就可以通过它来得到菜单的数目或者是内容,当然如果本来就是创建了很多的右键菜单而是分别显示的话,那就更好.我在msdn和sdk里面都找不到获得contextmemu句柄的办法,不知道是怎么回事
2.在另一个程序中选右键菜单的第一项
3.在spy++中找2中对应的消息(窗口句柄及消息参数)
4.用SendMessage给3中的窗口发消息
other:没法监视文字(它可能不是传统意义上的菜单),还是监视消息参数比较好.
Creating a Resource List
The following example creates a list of every resource in the Hand.exe file. The list is written to the Resinfo.txt file. The code demonstrates how to load the executable file, create a file in which to write resource information, and call the EnumResourceTypes function to send each resource type found in the module to the application-defined callback function EnumTypesFunc. See EnumResTypeProc for information on callback functions of this type. This callback function uses the EnumResourceNames function to pass the name of every resource within the specified type to another application-defined callback function, EnumNamesFunc. See EnumResNameProc for information on callback functions of this type. EnumNamesFunc uses the EnumResourceLanguages function to pass the language of every resource of the specified type and name to a third callback function, EnumLangsFunc. See EnumResLangProc for information on callback functions of this type. EnumLangsFunc writes information about the resource of the specified type, name, and language to the Resinfo.txt file. Note that the lpszType in EnumResTypeProc is either a resource ID or a pointer to a string (containing a resource ID or type name); lpszType and lpszName in EnumResNameProc are similar. To use an enumerated resource, take the resource name or ID and call the appropriate function. For example, to load a string resource (RT_STRING), if lpszName in EnumResNameProc gives the resource ID (either directly or in a string that starts with the pound sign (#)), call LoadString. Otherwise, lpszName points to a string containing the resource name, so do the following: call FindResource or FindResourceEx with the resource name to get the resource handle;
call LoadResource with the resource handle to get the global handle;
call LockResource with the global handle to get a pointer to the resource data.
The Updating Resources code follows a similar pattern for a dialog box resource. char szBuffer[80]; // print buffer for EnumResourceTypes
DWORD cbWritten; // number of bytes written to res. info. file
int cbString; // length of string in sprintf
// Declare callback functions.
