HomoloCzh have recently received a small partner, said demand is to have a write c # scanning, access to other functions winfrom image control is embedded in java Swing them, so that small partners very upset ah, and has been studied from the year ago period using a variety of methods.
jcob, comfyj, jawin, jni, jna so many ways. (Either directly dll calls a method, called indirectly with some C a shell package, and then use java call, or even have come direct calls coming exe) clearly talk winfrom current demand is fitted into stepped swing which involves
Between procedure calls and embedded development, so it is quite difficult. Small Internet to find partners for a long time, did not find the information for reference. The last to give up.
I do also out of curiosity, although most of them are now doing java focus on back-office services. Performance server architecture of control CS rarely do with java SWING, but because of a small partner chat knew this thing, then go online looked really very few similar requirements post, almost no one done it before is not currently recommended do not know the future will not, because from then 1.4 java jdk not been updated swing piece, and this piece of founding the Web. But it happens in the degree of your mother and chat, I found a post that is java SWT word document can be displayed, and then I thought there should be a door try holding the attitude, did not think really successful ha ha. We did not talk much and paste the code process
Principle: The SWT display video box control, and then on the swing SWT interface, interactive call and then implemented by SWT dll method calls package
premise: use of OCX or dll must be registered in the system registry, installation control installation or by a command packet regsvr32 xxxx.dll
The JVM 1. First digit (32-bit or 64-bit) org.eclipse.swt.xxx.jar introduced which corresponds to the project to see if the number of bits of the JVM does not know Baidu on their own, there are many ways of
There is one kind cmd teach you to execute java -version
2. To call the ocx environment variables into the system directory, or jdk bin directory, or load your own
Here 2.1 is the interface implementation class code
*
* Procedure:
* Face acquisition control installation 1.
* 2. Verify or install dll ocx regsvr32 xxx.ocx already registered in the registry 32 or xxx.dll is the regsvr
* 3. run the software, 64, 32, or confirm JVM32 Please load position org.eclipse.swt.x86.jar, 64-bit load the org.eclipse.swt.x64.jar
* 4. 64 64 JDK dynamic load library, JDK load 32-bit 32-bit dynamic link library
* 5. direct executes the main function of the operating face acquisition program
